Technical field [0001] The invention relates to a mobile communication system, in which the mobile station device measures the quality of reception of signals received from the base station device and transmits information on the quality of reception to the base station device, while the base station device allocates resources based on the reception quality information received from the mobile station device and applies to the base station device and the mobile station device, which are used in the mobile communication system.
Background of the invention [0002] The demand for data communication in the field of mobile communication systems has been growing recently. To adapt the increase in data communication due to data transmission requirements, various techniques for greater frequency utilization have been proposed as such. One technique for improving the efficiency of frequency use is access to orthogonal frequency division multiplication ( OFDMA - Orthogonal Frequency-Division Multiple Access). OFDMA refers to the modulation method used for all cells in a communication area of cells to communicate with each other using the same frequency and can achieve faster data communication.
[0003] For scheduling transmission packets in an OFDMA system, it is well known in the manner in which a mobile station apparatus transmits a channel quality indicator (ang. CQI - Channel Quality Indicator), which is information indicating the quality of the downlink link reception status for subcarriers in a wide band, while the base station device performs packet scheduling based on CQI subcarriers in a wide band received from each mobile station device.
[0004] In addition, a technique is also well known in which for scheduling transmission packets in an orthogonal frequency division multiplexing system. OFDM - Orthogonal Frequency-Division Multiplexing), which uses many subcarriers, and mobile station devices estimate each state of the downlink channel (frequency characteristics, i.e. frequency-dependent transmission loss characteristics) and transmit to the base station device information obtained by quantizing each channel state, while the base station device determines the subcarriers to be allocated for each mobile station device based on the transmitted information (Patent Document 1).
[0005] Fig. 14 shows a prior art communication method between a base station device and a mobile station device. After receiving information about the downlink from the downlink used to measure the quality of the reception from the base station device, the device
- 2 mobile stations measure the quality of each channel based on the downlink information to create a propagation path channel profile.
[0006] The channel profile created by the mobile station device is transmitted from the mobile station device to the base station device as reception quality information via an uplink. Based on the reception quality information, the base station device performs adaptive modulation and coding or selective frequency scheduling for signals transmitted from the base station device to the mobile station device.
[0007] For the transmission of reception quality information to a base station device by a mobile station device, in Evolved Universal Terrestrial Radio Access studied under the consortium
The Third Generation Partnership Project (3GPP - Thrird Genration Partnership Project), which is an international standardization project, is being examined whether reception quality information is transmitted via a dedicated uplink control channel (physical uplink control channel, hereinafter referred to as "PUCCH" - Physical Uplink Control Channel).
[0008] For example, in Non-patent Document 1, a method has been proposed for transmitting, in transmitting reception quality information from a mobile station device to a base station device, reception quality information by using PUCCH or PUSCH depending on the type of services differing in the information required reception quality.

Presentation of the invention
Problems to be Solved by the Invention [0014] However, there is no specific description in the prior art about mapping relevant information while transmitting uplink data and reception quality information from a mobile station device to a base station device.
[0015] As used herein, the phrase "relevant information mapping" refers to the specific mapping of relevant information (uplink data and reception quality information) as transmission data, i.e., their specific mapping in a PUSCH resource unit (minimum unit of time-frequency block PUSCH) in the simultaneous transmission of uplink data and reception quality information from the mobile station device to the base station device.
[0016] In the event that the uplink data and the reception quality information are simultaneously transmitted from the mobile station device to the base station device, the base station device may separate the respective data by recognizing the mapping of the uplink data and the reception quality information. The base station apparatus can extract only reception quality information from simultaneously transmitted uplink data and reception quality information, and effectively transmit downlink data by performing adaptive modulation and coding and / or selective frequency scheduling based on the information obtained.
[0017] The amount of information from the control signals transmitted from the base station apparatus to determine the mapping of the uplink data and the reception quality information simultaneously transmitted from the mobile station apparatus must be kept small. Downlink resources would be inefficiently used if the base station device transmitted control signals to determine the mapping of relevant information each time in transmitting reception quality information from the mobile station device.
[0018] In addition, there is another need to reduce any delay in changing the mapping of uplink data and reception quality information simultaneously transmitted from a mobile station device. If there is any significant delay in changing the mapping of the respective information while transmitting the uplink data and the reception quality information from the mobile station device, there would be another significant delay until the reception quality information arrives at the base station device. The base station device uses adaptive modulation and coding and / or
- 4 selective frequency scheduling for the downlink data according to the reception quality information transmitted from the mobile station device.
[0019] If there is any significant delay in transmitting reception quality information, the modulation and coding and frequency band used for transmitting the uplink data most appropriate for the mobile station device will change. Even if the base station device performs adaptive modulation and coding and / or selective frequency scheduling based on the reception quality information with a significant delay, it will fail to control the mobile station device in a manner appropriate for the mobile station device at that time. This would result in inefficient use of downlink resources.
[0020] In addition, a modulation scheme and coding rate ( coding rate) to be determined in the transmission of the uplink data are determined by the base station device estimating the path propagation environment based on the uplink data or the reference signal transmitted from the mobile station device. Therefore, in the event that the uplink data and the reception quality information are simultaneously transmitted, if the modulation scheme and the encoding rate of the reception quality information cannot apply to this uplink data specified by the base station device, the probability of successful transmission of the reception quality information decreases .
[0021] The description above also applies to ACK (/ NACK Hybrid Automatic
Repetition Requests HARQ - Hybrid Automatic Repeat Request) for downlink data, which is also uplink information, such as reception quality information. Thus, the amount of control signal information transmitted from the base station device to determine the mapping of the uplink and ACK / NACK data simultaneously transmitted from the mobile station device to the base station device must be kept small. Also, the delay in changing the mapping must be small. In addition, the modulation scheme and the ACK / NACK coding rate simultaneously transmitted with the uplink data must apply to the uplink data specified by the base station device. Any specific descriptions of these three conditions: the amount of information control information to determine the mapping of the respective information, the delay appearing in the change of the mapping of the respective information and compliance with the modulation scheme and the coding rate of the uplink data are not provided in the prior art.
In summary, what is important is how to determine a method of simultaneously transmitting uplink data and reception quality information as well as uplink and ACK / NACK data from the mobile station device to the base station device. To address the problem, the amount of control signal information must be taken into account to determine the mapping of relevant information from the base station device, the delay occurring in the change in mapping of relevant information, and compliance with the modulation scheme and encoding rate of the uplink data determined by the base station device.
[0023] The invention was made in the light of such circumstances and provides a mobile communication system, base station equipment and mobile station equipment, which can reduce the amount of control information to determine the transmission method for simultaneously transmitting uplink data and reception quality information, as well as uplink and ACK / NACK data, reduce the delay appearing in the change of transmission method and perform mapping of the uplink data and the reception quality information as well as these uplink and ACK / NACK data, in accordance with the modulation scheme and encoding rate of the uplink data determined by the base station device.
Means for solving the problems [0024] To achieve the above objectives, the invention provides the following means. Namely, the mobile communication system according to the invention is directed to the mobile communication system according to claim. 1.
[0025] In addition, the mobile communication device according to the invention is directed to the mobile station device according to claim 3.
[0026] In addition, the method of communication of the mobile station device in the mobile communication system is directed to the method of communication according to claim. 5.
[0027] According to the invention, because the base station device transmits control information to the mobile station device to determine the transmission format for the mobile station device for the simultaneous transmission of uplink data and reception quality information, and the mobile station device simultaneously transmits to the base station device uplink data and information about the quality of reception based on a specific transmission format in case of receiving control information from the base station device, control signal transmission for determining the mapping of relevant information may be omitted and downlink resources may be efficiently utilized. In addition, if the transmission format is determined based on the method of allocating the uplink resources, the uplink data mapping and the reception quality information may be changed, and the transmission of control signals to change the mapping of the respective information may be omitted. As a result, the delay appearing in changing the mapping of the respective information can be reduced.

Best methods for carrying out the invention [0030] Various embodiments of the invention will now be described with reference to the diagrams.
FIRST EMBODIMENT [0031] The mobile communication system according to the invention will be described first. The mobile communication system includes a base station device and a mobile station device. FIG. 1 is a block diagram showing a schematic configuration of a base station apparatus according to a first embodiment of the invention. Base station apparatus 100 includes data control unit 101, modulation coding unit 102, mapping unit 103, reverse fast Fourier transform unit (IFFT), radio transmit unit 105, radio receive unit 106, fast Fourier transform unit (FFT) 107, unit 108 demodulation decoding, data extraction unit 109, scheduling unit 110, information transmission control unit 111 and antenna 112. The information transmission control unit 111 includes the modulation coding control unit 111a and the selective frequency scheduling unit 111b.
[0032] Transmission data for transmission to each mobile station device and control data are input into the data control unit 101 at the base station device 100 and all data is transmitted sequentially to the mobile station devices according to the instructions of the scheduling unit 110. Modulation coding unit 102 applies modulation and error correction coding to signals input from data control unit 101 based on the modulation scheme and coding rate determined by the modulation and coding control unit 111a and sends each data to the mapping unit 103. The mapping unit 103 maps the data input from the modulation coding unit 102 to each subcarrier based on the frequency selective scheduling information provided by the frequency selective scheduling unit 111b and sends each data to the IFFT unit 104.
[0033] IFFT unit 104 applies inverse fast Fourier transform to data input from mapping unit 103, then converts the data input into the digital baseband signals and finally sends signals to the radio transmission unit 105. In the radio transmission unit 105, digital-analog conversion is applied to signals sent from the IFFT unit 104 and the resulting signals are then converted up to a frequency suitable for transmission and transmitted to each mobile station device via antenna 112.
[0034] Scheduling unit 110 performs scheduling for both downstream and upstream links based on control information, such as resource areas available for each mobile station device, intermittent transmit / receive cycles, data channel format, and buffer state. The modulation and coding control unit 111a determines the modulation scheme and coding rate to be applied to each data based on the reception quality information transmitted from the mobile station device and sends it to the modulation coding unit 102. The selective frequency scheduling unit 111b applies selective frequency scheduling to each given based on the reception quality information transmitted from the mobile station device and sends the result to the mapping unit 103.
[0035] Fig. 2 is a block diagram showing a schematic configuration of a mobile station device according to a first embodiment of the invention. Mobile station apparatus 200 includes data control unit 201, modulation coding unit 202, mapping unit 203, inverse Fast Fourier Transform Unit (IFFT), radio transmit unit 205, radio receive unit 206, Fast Fourier Transform unit (FFT) 207, unit 208 demodulation decoding, data extraction unit 209, reception quality control unit 210 and antenna 211. The reception quality information control unit 210 includes the reception quality information generating unit 210a and the reception quality measurement unit 210b. It should be noted here that the receiving unit is composed of a radio receiving unit 206, a 207 FFT unit, demodulation decoding units 208, data extraction units 209 and a reception quality information control unit 210, while the transmission unit is composed of data control unit 201, units 202
- 9 modulation coding, mapping units 203, inverse fast Fourier transform units (IFFT) and radio transmission units 205.
[0036] Transmission data for transmission to the base station device and control data are input to the data control unit 201 of the mobile station device 200 and this data is transmitted sequentially to the base station device. The modulation coding unit 202 applies modulation and error correction coding to the signals input from the data control unit 201, and sends each data to the mapping unit 203. The mapping unit 203 maps the data input from the modulation coding unit 202 to each subcarrier and sends each data to the IFFT unit 204.
[0037] IFFT unit 204 applies inverse fast Fourier transform to symbol sequences introduced from mapping unit 203, converts them to temporary baseband digital signals and sends them to radio transmission unit 205. In the radio transmission unit 205, the digital-analog conversion is applied to the output signals from the IFFT unit 104 and the resulting signals are converted up to a frequency suitable for transmission and then transmitted to the base station apparatus via antenna 211.
[0038] The reception quality measurement unit 210b of the reception quality information control unit 210 measures the quality of the reception of signals received from the base station apparatus. The reception quality information generating unit 210a generates the reception quality information to be transmitted to the base station apparatus based on the information measured by the reception quality measurement unit 210b.
[0039] A receiving unit composed of a radio receiving unit 206, 207 FFT units, 208 demodulation decoding units, data extraction units 209 and reception quality information control units 210 receive control information to determine the transmission format of the information to be transmitted using an uplink from the base station device and based on the specified format, recognizes the transmission format for transmitting uplink data and reception quality information, as well as uplink and ACK / NACK data.
[0040] A transmission unit of data control unit 201, modulation coding units 202, mapping units 203, IFFT units and radio transmission units 205, simultaneously transmits uplink data and reception quality information as well as uplink data to the base station apparatus. and ACK / NACK in a transmission format recognized by the receiving unit.
[0041] Fig. 3 shows an exemplary uplink data mapping and reception quality information transmitted from the mobile station device to the base station device according to the first embodiment of the invention. FIG. 3 represents figure 1 and figure 2. For each form, the vertical direction represents the time axis and includes here fourteen OFDM symbols as an example of resources allocated by the base station device. Many known reference symbols (pilot signals, later designated 'RS') used to estimate the propagation path for data demodulation, different numbers
10 reception quality information and uplink data between Form 1 and Form 2 are mapped to these fourteen OFDM symbols.
[0042] On the other hand, the horizontal direction represents the frequency axis. By adopting the PUSCH resource unit (the minimum PUSCH time-frequency block unit) as one resource block, the base station device allocates the resources of one resource block in form 1 and these two resource blocks in form 2, towards the frequency axis.
[0043] The mobile station device transmits data using PUSCH according to the resource allocation determined by the Physical Downlink Control Channel, which will be referred to as "PDCCH" from the base station device. In other words, this downlink control channel (PDCCH) is a signal enabling uplink transmission (i.e., L1 / L2 allocation).
[0044] In this embodiment, the mobile station apparatus performs mapping of information in simultaneous transmission of uplink data and reception quality information according to resources allocated by the base station apparatus using L1 / L2 allocation.
[0045] More particularly, form 2 of Fig. 3 shows that the mobile station device allocates using the L1 / L2 allocation from the base station device, resources having the number of fourteen OFDM symbols towards the time axis and one resource block towards the frequency axis, and performs mapping of uplink data and reception quality information related to allocated resources. Here, the element consisting of the OFDM symbol and one subcarrier is referred to as the "resource element". In this example, if the resource block is composed of twelve subcarriers, the number of resource elements for one OFDM symbol and one resource block is twelve and the number of resource elements in one resource block is 168.
[0046] Similarly, form 2 of Fig. 3 illustrates that the mobile station device allocates using L1 / L2 allocation from the base station device, resources having the number of fourteen OFDM symbols in the direction of the time axis and two resource blocks in the direction of the frequency axis, and performs mapping of uplink data and reception quality information related to allocated resources.
[0047] Here it can be determined in advance what type of resources the base station device allocates using the L1 / L2 allocation and according to how the mobile station device maps the uplink data and the reception quality information. Thus, according to an embodiment, it is predetermined that in the event that the base station device allocates resources having the number of fourteen symbols towards the time axis and one resource block towards the frequency axis, the mobile station device performs mapping of uplink data and information on the quality of reception represented by figure 1. Similarly, it is also predetermined that in the event that the base station device allocates resources having fourteen OFDM symbols towards the time axis and two resource blocks towards the frequency axis, the mobile station device performs mapping of uplink data and reception quality information. represented by figure 2.
[0048] Because when allocating resources to a mobile station device using L1 / L2 allocation, the base station device knows in advance what type of mapping is (e.g. form 1 or form 2) of the uplink data and the reception quality information transmitted simultaneously, the base station device may separate the uplink data and the reception quality information. Then, the base station device may apply adaptive modulation and coding and / or selective frequency scheduling to downlink data based on dedicated reception quality information.
[0049] Next, Form 1 and Form 2 presented above as an example of mapping uplink data and reception quality information simultaneously transmitted from the mobile station device to the base station device will be described in more detail. Form 1 has more information about the quality of reception in the direction of the timeline (including fourteen OFDM symbols here). In this form, the reception quality information transmitted from the mobile station device to the base station device is mapped to be more tolerant of temporary changes in the propagation path. On the other hand, form 2 has more information about the quality of reception in the direction of the frequency axis. In this form, the reception quality information transmitted from the mobile station device to the base station device is mapped to be more tolerant of frequency changes in the propagation path.
[0050] Similarly, Fig. 4 shows yet another example mapping of uplink data and reception quality information transmitted from a mobile station device according to the first embodiment of the invention. On the left side of the figure, a figure similar to figure 1 in Fig. 3. Figure 3 from Fig. 4 shows that the reception quality information can simply be mapped at a lower (or higher) frequency for resources allocated by the base station device. With this simple mapping, the base station device can separate uplink data and reception quality information without any complicated processes.
[0051] Similarly, Fig. 5 shows yet another example mapping of uplink data and reception quality information transmitted from a mobile station device according to the first embodiment of the invention. On the left side of the figure a figure 4 is shown similar to figure 1 in fig. 3. Form 4 is significantly different from form 1 in that the reception quality information is mapped towards the frequency axis in a dispersed manner and in that the uplink data is placed where there was reception quality information. Each area for information about the quality of reception is composed of one or more groups of resource elements. Thus, as shown in form 5 of Fig. 5, by mapping information on the quality of reception towards the frequency axis in a dispersed manner, more tolerant mapping against frequency changes in the propagation path can be achieved, while a resource of the same size as Form 4 is still used to transmit reception quality information (although four resource element groups in the form of 4 and two resource element groups in the form of 5 are used as one OFDM symbol, the character size is the same, because the second form uses two resource blocks in the direction of the frequency axis).
[0052] Furthermore, fig. 6 to 8 show an exemplary mapping of uplink data and reception quality information transmitted from a mobile station device according to the first embodiment of the invention. These figures are significantly different from Fig. 3 to 5 in that in each embodiment the mapping of the uplink data and the reception quality information is represented with a gradation pattern. Figures depicted on the left side of Fig. 6 to 8 are shown as figure 1 'associated with figure 1 shown in Fig. 3.
[0053] In Fig. 6 to 8, conceptually, gradation patterns show that uplink data and reception quality information are also mapped in a single resource element in a mixed manner. More specifically, they are mixed before being mapped to a resource element. In these figures, the black part and the white part of the gradation pattern indicate reception quality information and uplink data, respectively. The uplink data and reception quality information are mixed before mapping to the resource element and then mapped to twelve resource elements, for example. Thus, conceptually, one resource element contains part of the reception quality information and part of the uplink data.
[0054] Form 1 'in Fig. 6 shows the mapping of uplink data and reception quality information in the case where one resource block is determined by L1 / L2 allocation. In the form 1 ', the uplink data and reception quality information are mapped in a mixed manner in four OFDM symbols from fourteen OFDM symbols. On the other hand, figure 6 in Fig. 6 shows the mapping of uplink data and reception quality information when two resource blocks are determined by L1 / L2 allocation. In this embodiment, 6 of the four OFDM symbols of the fourteen OFDM symbols, uplink data and reception quality information are mapped as mixed-transmitted resources and are further mapped using two resource blocks in the frequency direction. Figure 6 from Fig. 6 is a character who has been mapped so that the amount of information about the quality of reception can increase as the number of allocated resource blocks increases. Also for form 1 'and form 6 the black part showing information about the quality of reception with gradation is presented with the same density. This indicates that the relations of the uplink data and the reception quality information combined in form 1 'and form 6 are the same.
[0055] Form 1 'in Fig. 7 is similar to the 1 'form shown in Fig. 6. Also figure 7, like figure 6 in fig. 6, mapping the uplink data and reception quality information in the case where these two resource blocks are determined by L1 / L2 allocation. In this embodiment 7, in two OFDM symbols of the fourteen OFDM symbols, the uplink data and reception quality information are mixedly mapped as transmitted resources, and are further mapped using two resource blocks in the frequency direction. Thus, character 7 is a character that has been mapped so that the amount of reception quality information cannot increase as the number of allocated resource blocks increases. Also for Form 1 'and Form 7, the black portion showing gradation reception quality information is shown at the same density, indicating that the ratios of mixed uplink data and reception quality information are the same.
[0056] Form 1 'in Fig. 8 is similar to the 1 'form shown in Fig. 6. Form 1 'and form 8 are significantly different in that each part of the block in the gradation pattern, indicating the reception quality information, is presented with different density. For example, the black part of form 8 has a lower density. This implies that the ratios of the mixed uplink data and the reception quality information in the form 1 'and the form 8 are different, and implies that the relations of the uplink data and the reception quality information are mixed before mapping to the resource element. In fig. 8 it is shown that the amount of total reception quality information information to be transmitted in the form 1 'and form 8 is the same.
[0057] The details will now be described with reference to a more specific example. For the form 1 'of Fig. 8, assuming that the reception quality information with the number "4" and the uplink data with the number "6" are mixed in a resource having one symbol and one resource block, then for form 8, the reception quality information with the number "2" and the uplink data with the number "8" would be mixed up in such a resource. Thus, the amount of reception quality information contained in the resource of one symbol and one resource block becomes smaller. However, compared to form 1 ', form 8 has a double number of resource blocks in which uplink data and reception quality information are mixed for transmission. Thus, the reception quality information transmitted over the entire form 1 'and this in the whole form 7 have the same amount of information.
[0058] If the uplink data and reception quality information as shown in Fig. 6 up to 8 are mixed before mapping to a resource element, and the base station device receives information mapped in a distributed manner into multiple resource elements, then the base station device can be folded to be able to extract the received information as one integrated information (quality information receive, uplink data) after receiving all distributed resource elements.
[0059] As described above, with the conceptual mapping shown in Fig. 6 up to 8, where the uplink data and reception quality information are mixed before mapping to the resource element, the mobile station device does not require specifying where the resource element containing the uplink data and the reception quality information should be mapped and can effectively perform the tasks needed to mapping information to a resource element. Such mixing of the uplink data and the reception quality information can be done by, for example, entering the reception quality information on the modulation symbol to the place where the uplink data was, and by applying, for example, discrete Fourier conversion to information.
[0060] The mobile station apparatus may perform mapping of the uplink data and the reception quality information as shown in Fig. 3 up to 8, depending on the resources allocated by allocating L1 / L2 from the base station device. To describe the fig. 6 more specifically, the mobile station device may change the ratio of the uplink data and the reception quality information to be mixed, depending on the resources allocated by allocating L1 / L2 from the base station device. Briefly, referring to Fig. 8, the mobile station device can change the density of the black part,
- 14 indicating information on the quality of reception, depending on the resources allocated by the L1 / L2 allocation from the base station device. It should be noted here that the mapping of information described above is only an example and for example the mapping shown in Figs. 3 to 8 can be combined and any mapping of uplink data and reception quality information for simultaneous transmission from a mobile station device may be possible.
[0061] The method of mapping reception quality information on groups of resource elements described above can be roughly divided into two parts. One is for increasing the amount of reception quality information resources relative to those resources allocated for the uplink data. For example, as in forms 1, 1 'and 6, in the case where four groups of resource elements are mapped in one resource block as reception quality information, if two resource blocks are allocated, the reception quality information is transmitted in eight element groups resources. The second is to change the mapping so that the amount of resources (number of resource elements) of the quality of reception information can always be constant, depending on the resource allocation for the uplink data. An example of this mapping is each of the mappings in the form 2, 3, 5, 7 or 8. In this embodiment, the modulation scheme and coding rate used for the reception quality information are set as fixed.
[0062] Now the first and second mapping methods described above are defined as "information enhancing type" and "information retaining type," respectively. It will also describe how to control each type of mapping method. First, the control method for the type of information increasing mapping method will be described in the base station device. When performing an information enhancing mapping type, the base station apparatus may transmit RRC signaling to the mobile station apparatus, including information indicating the minimum amount and / or maximum amount of resources at which the reception quality information may be mapped.
[0063] It should be noted here that, for example, the minimum amount of resources at which reception quality information can be mapped can be set as the amount of resources of reception quality information (e.g. number of modulation symbols, number of resource elements, amount of information, etc.) that can be mapped in one resource block. Thus, this is the maximum amount of reception quality information resources that can be mapped in one resource block. Meanwhile, the maximum amount of resources at which reception quality information can be mapped can be set as the maximum amount of resources for reception quality information (e.g. number of modulation symbols, number of resource elements, amount of information, etc.) that can be mapped in resource blocks allocated by the base station device.
[0064] The mobile station apparatus continues to perform mapping of uplink data and reception quality information with an information enhancing type (see forms 1, 1 'and 6) based on the number of resource blocks and / or the size of the transport block allocated by L1 / L2 allocation before reaching the minimum amount of resources in which information about the quality of reception can be mapped (maximum amount of information about
- 15 reception quality for mapping in one resource block), set by signaling RRC from the base station device.
[0065] In addition, in case of, when the calculated resources based on L1 / L2 allocation in mapping reception quality information exceed the maximum amount of resources, in which information about the quality of reception can be mapped, set by signaling RRC from the base station device, the mobile station device maps uplink data and information about the quality of the reception and so, that the amount of resources does not exceed the maximum amount of resources set by the base station device, by reducing the amount of resources in the direction of time to map reception quality information, as shown in the form 7, or by reducing the amount of uplink data reduction to reduce the ratio of resources to mapping reception quality information, as shown in the form 8.
[0066] Furthermore, in the case of when the calculated resources based on L1 / L2 allocation in the mapping of reception quality information fall below the minimum amount of resources, in which information about the quality of reception can be mapped, set by signaling RRC from the base station device, the mobile station device maps uplink data and information about the quality of the reception and so, that the amount of resources does not fall below the minimum amount of resources set by the base station device, by increasing resources in the direction of time to map reception quality information, as shown in the form 7, or by increasing the amount of uplink data reduction to increase the resource ratio for mapping reception quality information, as shown in the form 8.
[0067] In this way, the base station apparatus transmits RRC signaling containing information indicating a minimum amount and / or a maximum amount of resources in which the reception quality information can be mapped. After receiving the signal, the mobile station device changes the mapping of the uplink data and the reception quality information and transmits them simultaneously. Thus, even when the resources for transmitting the reception quality information calculated based on the L1 / L2 allocation are larger (i.e. when uplink data having a larger amount of information is transmitted), it is possible to avoid the transmission of reception quality information with a certain amount or more (i.e. reception quality information having too much information) by the mobile station device, and a significant increase in uplink load caused by the transmission of reception quality information can be avoided. Also, even when the resources for transmitting reception quality information calculated based on L1 / L2 allocation are smaller (i.e. when uplink data having a smaller amount of information is transmitted), the mobile station device may transmit the reception quality information with some or more (i.e. information on the reception quality set by a minimum amount), and the quality of the reception quality information can be kept above a certain level. Moreover, by setting a minimum amount that can be calculated based on the allocation of L1 / L2 as the minimum amount, you can avoid the transmission of reception quality information that falls below the minimum amount by the mobile station device. Here, by defining the equation for the resources to transmit information on the quality of reception so that it does not exceed the maximum quantity and not
- 16 fell below the minimum amount, each of which can be calculated based on the allocation of L1 / L2, the maximum amount or minimum amount need not be set by using RRC signaling.
[0068] Next, a control method for a mapping method in a base station device of the information retaining type will be described. When the mobile station device performs a retaining mapping type information, the base station device may transmit to the mobile station device RRC signaling containing information indicating a certain amount (value retained later) of the resources in which the reception quality information may be mapped. It should be noted here that retaining the amount of resources in which information about the quality of the reception can be mapped can be defined as a certain amount of resources (e.g. number of symbols, number of resource elements, amount of information, etc.) information about the quality of resources, which can be mapped in resource blocks allocated by the base station. If RRC signaling from the base station device sets the stored value to the size "10", the mobile station device maps the uplink data and the reception quality information having the size "10", no matter what the number of resource blocks and / or transport block sizes are allocated by L1 / L2 allocation.
[0069] In addition, in the case of when the amount of resources calculated in the mapping of reception quality information exceeds the saved amount of resources, in which information about the quality of reception can be mapped, set by signaling RRC from the base station device, the mobile station device maps uplink data and information about the quality of the reception and so, that the amount of resources does not exceed the saved amount set by the base station device, by reducing the amount of resources in the direction of time to map reception quality information, as shown in the form 7, or by reducing the amount of uplink data reduction to reduce the proportion of resources to map reception quality information, as shown in the form 8.
[0070] Furthermore, in the case of when the amount of resources calculated in the mapping of reception quality information falls below the amount of resources saved, in which information about the quality of reception can be mapped, set by signaling RRC from the base station device, the mobile station device maps uplink data and information about the quality of the reception and so, that the amount of resources does not fall below the stored amount set by the base station device, by increasing the amount of resources in the direction of time to map reception quality information, as shown in the form 7, or by increasing the degree of reduction of uplink data to increase the amount of resources for information on the quality of reception, as shown in the form 8.
[0071] In this way, the base station apparatus transmits RRC signaling containing information (stored value) indicating a number of resources at which reception quality information can be mapped. After receiving the signal, the mobile station device simultaneously transmits uplink data and a certain amount of information about the quality of the reception. Thus, the mobile station device can transmit a certain amount of reception quality information regardless of the resources allocated by L1 / L2 allocation.
[0072] Fig. 9 is a sequence diagram of the operation of the base station device and the mobile station device according to the first embodiment of the invention. First, the base station device allocates resources for the mobile station device for transmitting uplink data using L1 / L2 allocation (step S61). Here it has been assumed that resources are allocated according to form 1 in Fig. 3. Then, after receiving the L1 / L2 allocation from the base station device, the mobile station device simultaneously transmits uplink data and reception quality information with information mapping (from form 1, here) associated with the allocated resources (step S62).
[0073] Then, the base station device again allocates resources for the mobile station device for transmitting uplink data using L1 / L2 allocation (step S63). Here it has been assumed that resources are allocated according to form 2 in Fig. 3. Then, after receiving the L1 / L2 allocation from the base station device, the mobile station device simultaneously transmits uplink data and reception quality information with information mapping (from form 2, here) associated with the allocated resources (step S64). Here, the mapping of the uplink data and the reception quality information related to the allocated resources by the base station device using the L1 / L2 allocation can be predetermined.
[0074] As described above, by determining in advance the mapping of the uplink data and the reception quality information according to the allocation of the uplink data resources from the base station device and by the mobile station device performing the mapping of the uplink data and the reception quality information according to the allocation of the uplink data resources from the base station device . transmission of control signals to determine the mapping of relevant information is not necessary. As a result, inefficient use of downlink resources can be reduced. In addition, as the mapping of information in the simultaneous transmission of uplink data and link quality information is changed according to the method of allocating uplink resources, any control signals for changing the mapping of the respective information are not required and the delay in changing the mapping of the respective information may be reduced.
[0075] According to a first embodiment, the base station apparatus allocates resources for uplink data. However, due to mapping the reception quality information simultaneously transmitted with the uplink data in accordance with this resource allocation, the base station device consequently allocates resources for the uplink data and the reception quality information.
[0076] The first embodiment of the invention described above can be used when the uplink and ACK / NACK data are transmitted simultaneously. Thus, by determining in advance the uplink and ACK / NACK data mapping according to the allocation of the uplink data resources from the base station device and by the mobile station device performing the mapping of the uplink data and ACK / NACK according to the allocation of the uplink data resources from the station device baseline, control signals to determine the mapping of relevant information (uplink data and
- 18 ACK / NACK) are not necessary. As a result, inefficient use of downlink resources can be reduced. In addition, as the mapping of information in the simultaneous transmission of uplink and ACK / NACK data is changed according to how the uplink resource is allocated, any control signals to change the mapping of the respective information are not required and the delay in changing the mapping of the respective information may be reduced.
SECOND EMBODIMENT [0077] According to a second embodiment, the mobile station apparatus determines a modulation scheme and coding rate to be applied to reception quality information transmitted simultaneously based on the modulation scheme and coding rate applied to the uplink data allocated by the base station device using L1 allocation / L2.
[0078] The base station apparatus allocates resources for uplink data using L1 / L2 allocation and determines the modulation scheme and coding rate applied to the uplink data. After receiving this signal, the mobile station device determines the modulation scheme and coding rate to be applied to the reception quality information based on those applied to the uplink data. It should be noted here that the modulation scheme and coding rate to be applied to the uplink data by the base station device using the L1 / L2 allocation and those for use related to the reception quality information of the mobile station device can be predetermined.
[0079] Fig. 10 shows the content of a predefined table in a mobile communication system according to a second embodiment of the invention. As shown in fig. 10, the modulation scheme and the coding rate to be applied to the uplink data by the base station apparatus are associated with those to be applied to the reception quality information. As shown in Fig. 10, is predetermined when the base station device determines the use of the QPSK modulation scheme and 1/8 coding rate for the uplink data, then the mobile station device applies the QPSK or BPSK modulation scheme and the 1/8 or 1/16 coding rate information on the quality of reception for transmission. In addition, for example, it is predetermined when the base station device determines the use of a 16QAM modulation scheme and a 1/4 coding rate for uplink data, then the mobile station device uses a 16QAM or QPSK modulation scheme or a 1/4 or 1/1 coding rate 8 for information on the quality of reception for transmission.
[0080] Thus, for example, by a base station apparatus determining the use of a 16QAM modulation scheme and a 1/4 coding rate for uplink data, then the uplink data to which the 16QAM modulation scheme and a 1/4 coding rate are used, and there is information about the quality of reception, to which the 16QAM or QPSK modulation scheme and the coding rate 1/4 or 1/8, are simultaneously transmitted from the mobile station device. It should be noted here that the coding rate applied to the uplink data and the coding rate applied to the reception quality information may be
- 19 calculated from the modulation scheme and the size of the transport block to be transmitted. Thus, the modulation scheme and transport blocks to be transmitted can be predetermined.
[0081] This connection between the modulation scheme and the encoding rate of the uplink data and those of the reception quality information can be mapped in a one-to-one or one-to-many manner. For the one-to-many mapping method, blind decoding described below will be used with multiple modulation schemes and uplink data coding rates associated with the modulation scheme and uplink data coding rate, demodulating the reception quality information in the base station device.
[0082] Generally, in the case where a high modulation scheme and a high coding rate are used to transmit information, a larger amount of information may be transmitted. On the other hand, in the case where a low modulation scheme and a low coding rate are used, very reliable information may be transmitted. As described above, by specifying in advance the modulation scheme and coding rate applied to the reception quality information related to those applied to the uplink data by the base station device, the modulation scheme and the coding rate of the reception quality information simultaneously transmitted with the uplink data can be compatible with those for uplink data, increasing the likelihood of successful transmission of reception quality information.
[0083] When determining the modulation scheme and coding rate to be applied to the uplink data using the L1 / L2 allocation for the mobile station device, the base station device may decode the corresponding information based on the modulation scheme and the encoding rate of the reception quality information because the station device the base knows the modulation scheme and coding rate of the reception quality information simultaneously transmitted with the uplink data. It should be noted here that in the event that the connection between the modulation scheme and the encoding rate of the uplink data and those to the reception quality information is mapped in a single duplex manner, decoding will be performed for all possible modulation schemes and encoding rates (blind decoding) and then the results will be checked by a cyclic redundancy code ( CRC - Cyclic Redundancy Check) for correct modulation. The base station device applies adaptive modulation and coding and / or selective frequency scheduling to downlink data based on correctly demodulated reception quality information.
[0084] Fig. 11 is a sequence diagram of the operation of the base station device and the mobile station device according to the second embodiment of the invention. First, the base station apparatus determines the modulation scheme and coding rate applied to the uplink data using L1 / L2 allocation (step S71). It is assumed here that the modulation scheme A and the coding rate B are defined as the modulation scheme and the coding rate applied to the uplink data. Then, after receiving the L1 / L2 allocation from the base station device, the mobile station device applies the modulation scheme and coding rate associated with modulation scheme A and coding rate B to
- 20 information about the quality of the reception. It is assumed here that the modulation scheme C and the coding rate D are used for information on the quality of reception associated with the modulation scheme A and the coding rate B, respectively. Then, the mobile station device simultaneously transmits to the base station device the uplink data to which the modulation scheme A is applied. and coding rate B, and reception quality information to which the C modulation scheme and coding rate D are applied (step S72).
[0085] Then, the base station apparatus again determines the modulation scheme and coding rate applied to the uplink data using L1 / L2 allocation (step S73). It is assumed here that the modulation scheme E and the coding rate F are defined as the modulation scheme and the coding rate applied to the uplink data. Then, after receiving the L1 / L2 allocation from the base station device, the mobile station device applies the modulation scheme and coding rate associated with the modulation scheme E and the coding rate F to receive quality information. It is assumed here that the modulation scheme G and the coding rate H are used for the reception quality information associated with the modulation scheme E and the coding rate F, respectively. Then, the mobile station apparatus simultaneously transmits to the base station apparatus, the uplink data to which the E modulation scheme and the F coding rate are applied, and the reception quality information to which the G modulation scheme and the H coding rate are applied (step S74). The modulation scheme and the coding rate of reception quality information associated with those applied to the uplink data by the base station device using the L1 / L2 allocation are predetermined herein.
As described above, the modulation scheme and the coding rate of the reception quality information simultaneously transmitted with the uplink data are predetermined according to those used for the uplink data determined by the base station device and the mobile station device may use the modulation scheme and the foot encoding to receive quality information according to the modulation scheme specification and coding rate to be applied to the uplink data. As a result, the reception quality information transmitted from the mobile station device to the base station device may follow the modulation scheme and the uplink data coding rate, increasing the probability of successful transmission of the reception quality information.
[0087] According to a second embodiment, the base station apparatus determines the modulation scheme and coding rate to be applied to the uplink data. However, as the modulation scheme and the encoding rate of the reception quality information simultaneously transmitted with the uplink data may also be determined, the base station apparatus consequently determines the modulation scheme and the encoding rate of the uplink data and the reception quality information.
[0088] The second embodiment of the invention described above can also be used when uplink and ACK / NACK data are simultaneously transmitted. Thus, by specifying in advance the modulation scheme and the ACK / NACK coding rate simultaneously transmitted with the uplink data according to the specifications for those to be applied to the uplink data from the base station device and through the device
- 21 mobile stations applying the modulation scheme and coding rate to ACK / NACK in accordance with the specifications for those to be applied to the uplink data from the base station device, ACK / NACK transmitted from the mobile station device to the base station device may follow the modulation scheme and the rate encoding uplink data, increasing the likelihood of successful transmission of reception quality information.
THIRD EMBODIMENT [0089] In connection with the first and second embodiments described above, the specific operating example of the base station device and the mobile station device will be described as the third embodiment. FIG. 12 shows the L1 / L2 allocation transmitted from the base station device to the mobile station device, information about the reception quality transmitted aperiodically, information about the reception quality transmitted periodically, uplink data from the mobile station device to the base station device, and the form of transmission for simultaneous transmission of the uplink data or uplink data and reception quality information. Periodic transmission of reception quality information from the mobile station device to the base station device can be achieved, for example, by transmitting the base station device with the allocation of L1 / L2 including one-bit information, by transmitting the mobile station device information about the quality of reception to the base station device after receiving the signal. Meanwhile, the periodic transmission of reception quality information from the mobile station device to the base station device can be achieved, for example, by transmitting RRC signaling with the base station device containing information setting periodicity to transmit reception quality information from the base station device to the mobile station device, by transmitting the mobile station device with information on the quality of reception with the periodicity of the base station device after receiving the signal. FIG. 12 shows, as an example, slot operations 1 to 10. Also on the right side of fig. 12 the processing flow of each slot is shown. In this figure, for the clarity of the processing flow, only some arrows are shown, so the arrow relating to the slot 1 indicates the processing flow from the base station device, and the other arrows referring to the other slots indicate the processing flow from the mobile station device that will be described in detail below.
[0090] Fig. 13 shows a predefined table of the modulation scheme and coding rate used in the third embodiment of the invention. The mobile station apparatus for which the modulation scheme and the coding rate are determined for the uplink data by allocating L1 / L2 from the base station device, applies the modulation scheme and the coding rate to the reception quality information using the table defined in Fig. 13. For example, if the base station device specifies the QPSK modulation scheme and 1/8 encoding rate of the uplink data, then the mobile station device uses the BPSK modulation scheme and the 1/4 encoding rate for reception quality information.
Returning to Fig. 12, the operations of each slot will be described. The base station apparatus transmits RRC signaling containing a minimum amount and / or a maximum
- the quantity and retained amount of resources in which information about the reception quality can be mapped for a mobile station device for simultaneous transmission of uplink data and reception quality information. For the sake of clarity, the minimum value, maximum value and retained value of the amount of information in which the reception quality information can be mapped are set to 10, 50 and 20 respectively. Here, these values are set only as an example, the minimum value and / or the maximum value and the stored value of the resources in which the reception quality information can be mapped, can be set, for example, using the number of modulation symbols, the number of resource elements for mapping quality information receiving and amount of information (number of bits) of information about the quality of reception before mapping the information about the quality of reception onto the elements of resources. In addition, in gap 1, all minimum values and / or maximum values and stored values are not necessary to set.
[0092] The slot 2 is a slot that is set in advance by the base station apparatus for transmitting reception quality information periodically. In slot 2, using L1 / L2 allocation, the base station device allocates resources used for the mobile station device to transmit uplink data. After receiving the signal, the mobile station device simultaneously transmits uplink data and reception quality information with the retaining information type of the mapping method using allocated resources.
[0093] Furthermore, the operation of the mobile station device in the slot 2 will be described. In the slot 2, the mobile station device transmits uplink data and reception quality information with the type of mapping method retaining information to the base station device. The information saving type of the mapping method is a mapping method for transmitting a certain amount of reception quality information with the stored quantity set by RRC signaling.
[0094] In particular, the stored value at which the reception quality information can be mapped is set to 20 by signaling RRC from the base station apparatus. In this case, using L1 / L2 allocation, the base station device sets one resource block to be used as resources, QPSK modulation scheme and 1/8 encoding rate for transmitting uplink data. Referring to the table shown in Fig. 13, this means that the modulation scheme and the coding rate of the reception quality information are set to BPSK and 1/16, respectively . With this control from the base station device, the mobile station device transmits, using one resource block, the uplink data to which the QPSK modulation scheme and 1/8 coding rate are applied, and the reception quality information with size 20 to which they are applied BPSK modulation scheme and 1/16 code rate. Thus, the number of resources used for this reception quality information is 320 (i.e. 20 * 1 * 16).
[0095] Also using L1 / L2 allocation, the base station apparatus sets to use two resource blocks as resources, QPSK modulation scheme and 1/8 encoding rate for transmitting uplink data. Referring to the table shown in Fig. 13, this means that the modulation scheme and the coding rate of the reception quality information are
- 23 set to BPSK and 1/16 respectively. Thus, with this control from the base station device, the mobile station device transmits, using two resource blocks, the uplink data to which the QPSK modulation scheme and 1/8 coding rate is applied, and the reception quality information with size 20, to which uses the BPSK modulation scheme and 1/16 code rate. Thus, the number of resources used for this reception quality information is 320 (i.e. 20 * 1 * 16).
[0096] Also, using L1 / L2 allocation, the base station apparatus sets two resource blocks to be used as resources, a QPSK modulation scheme, and a 1/4 encoding rate for uplink data transmission. Referring to the table shown in Fig. 13, this means that the modulation scheme and the encoding rate of the reception quality information are set to BPSK and 1/8, respectively. Thus, with this control from the base station device, the mobile station device transmits, using two resource blocks, the uplink data to which the QPSK modulation scheme and 1/4 code rate is applied, and the reception quality information with size 20, to which BPSK modulation scheme and 1/8 code rate are used. Thus, the number of resources used for this reception quality information is 160 (i.e. 20 * 1 * 8).
[0097] The slot 3 is a slot that is set by the base station apparatus for transmitting reception quality information aperiodically. The slot is also set by the control from the base station device to transmit the reception quality information in a triggered manner. In slot 3, using L1 / L2 allocation, the base station device allocates resources used for the mobile station device to transmit uplink data. After receiving the signal, the mobile station device simultaneously transmits uplink data and reception quality information with an information increasing type of mapping method using allocated resources.
[0098] Furthermore, the operation of the mobile station device in the slot 3 will be described. In slot 3, the mobile station device transmits uplink data and reception quality information with an increasing type of mapping method to the base station device. The information increasing type of mapping method is a mapping method for transmitting, according to the resources allocated by allocating L1 / L2 from the base station device, the reception quality information with the amount of resources to map the reception quality information, increased in the range of minimum value and / or maximum set value by signaling RRC.
[0099] In particular, hereby the minimum and maximum values at which the reception quality information can be mapped are set to 10 and 250, respectively, by signaling RRC from the base station device (here, the minimum value and the maximum value are set with the modulation scheme BPSK and coding rate 1/16). In this case, using L1 / L2 allocation, the base station device sets one resource block to be used as resources, QPSK modulation scheme and 1/8 encoding rate for transmitting uplink data. Referring to the table shown in Fig. 13, this means that the modulation scheme and the encoding rate of the reception quality information are set to BPSK and 1/16 respectively. With this control from the base station device,
- 24 the mobile station device transmits, using one resource block, uplink data to which the QPSK modulation scheme and 1/8 coding rate are used, and information about the reception quality with size 10 (10 * 1 * 1 * (1/16 ) / (1/16)), to which the BPSK modulation scheme and coding rate 1/16 are applied. Thus, the number of resources used for this reception quality information is 160 (i.e. 10 * 1 * 16).
[0100] Also, using L1 / L2 allocation, the base station apparatus sets three resource blocks to be used as resources for transmitting uplink data, QPSK modulation scheme and 1/8 coding rate. Referring to the table shown in Fig. 13, this means that the modulation scheme and the encoding rate of the reception quality information are set to BPSK and 1/16 respectively. Thus, with this control from the base station device, the mobile station device transmits, using three resource blocks, the uplink data to which the QPSK modulation scheme and 1/8 coding rate are applied, and the reception quality information with size 30 (10 * 3 * 1 * (1/16) / (1/16)), to which the BPSK modulation scheme and coding rate 1/16 are applied. Thus, the number of resources used for this reception quality information is 480 (i.e. thirty * 1 * 16).
[0101] In addition, using L1 / L2 allocation, the base station apparatus sets up to use three resource blocks as resources, a 16QAM modulation scheme, and a 1/4 encoding rate for transmitting uplink data. Referring to the table shown in Fig. 13, this means that the modulation scheme and the encoding rate of the reception quality information are set to QPSK and 1/4, respectively. Thus, with this control from the base station device, the mobile station device transmits, using three resource blocks, the uplink data to which the 16QAM modulation scheme and 1/4 code rate is applied, and the reception quality information with size 240 (10 * 3 * 2 * (1/4) / (1/16)), to which the QPSK modulation scheme and coding rate 1/4 are applied. Thus, the number of resources used for this reception quality information is 480 (i.e. 240 * (1/2) * 4). Here, this mapping method is an increasing type of mapping method for resource blocks, modulation scheme and coding rate.
[0102] Alternatively, using L1 / L2 allocation, the base station apparatus sets three resource blocks to be used as resources, a 16QAM modulation scheme, and a 1/4 encoding rate for transmitting uplink data. Referring to the table shown in Fig. 13, this means that the modulation scheme and the encoding rate of the reception quality information are set to QPSK and 1/4, respectively. Thus, with this control from the base station device, the mobile station device transmits, using three resource blocks, the uplink data to which the 16QAM modulation scheme and 1/4 code rate is applied, and the reception quality information with size 30 (10 * 3 * 1 * 1), to which the QPSK modulation scheme and coding rate 1/4 are applied. Thus, the number of resources used for this reception quality information is 60 (i.e. thirty * (1/2) * 4). Here, this mapping method is an increasing type of mapping method for resource blocks, and a retaining type of mapping method for modulation scheme and coding rate.
[0103] Also, using L1 / L2 allocation, the base station apparatus sets four resource blocks to be used as resources, 16QAM modulation scheme, and 1/4 code rate
- 25 for transmitting uplink data. Referring to the table shown in Fig. 13, this means that the modulation scheme and the encoding rate of the reception quality information are set to QPSK and 1/4, respectively. Thus, with this control from the base station device, the mobile station device transmits, using four resource blocks, the uplink data to which the 16QAM modulation scheme and 1/4 code rate is applied, and the reception quality information with size 320 (10 * 4 * 2 * (1/4) / (1/16)), to which the QPSK modulation scheme and coding rate 1/4 are applied. However, since the maximum resource value at which reception quality information can be mapped is set to 250 by signaling RRC from the base station device, the mobile station device transmits reception quality information with size 250 to the base station device. Thus, the number of resources used for this reception quality information is 500 (i.e. 250 * (1/2) * 4).
[0104] In slot 4 in Fig. 12, the base station apparatus transmits the normal L1 / L2 allocation. After receiving the signal, the mobile station device transmits uplink data to the base station device. A similar operation will be performed in slot 8.
[0105] Similar to slot 2, slot 7 is a slot that is positioned in advance by the base station apparatus for transmitting periodically information on reception quality. In slot 7, using the L1 / L2 allocation, the base station device allocates the resources used for the mobile station device to transmit uplink data. After receiving the signal, the mobile station device simultaneously transmits uplink data and reception quality information with the retaining information type of the mapping method using allocated resources. The information saving type of the mapping method is similar to that from slot 2.
[0106] Similar to slot 3, slot 10 is a slot that is set by the base station apparatus for transmitting reception quality information aperiodically. The slot is also set by the control from the base station device to transmit the reception quality information in a triggered manner. At slot 10, using L1 / L2 allocation, the base station device allocates resources used for the mobile station device to transmit uplink data. After receiving the signal, the mobile station device simultaneously transmits uplink data and reception quality information with an increasing type of mapping method using allocated resources. The information enhancing mapping method type is similar to that from slot 3.
[0107] As for the type-keeping mapping method information carried out in slots 2 and 7, as well as increasing the type information and retaining type information mapping method carried out in slots 3 and 10, the amount of information used for the reception quality information and the number of modulation symbols used for data an uplink can, for example, be calculated as shown in the equations below. Let Nrb, Md and Cd be the number of resource blocks, symbol rate for the modulation scheme, and coding rate, respectively, allocated by allocating L1 / L2 to transmit uplink data. In addition, let Mc and CC be the symbol foot for the schematic, respectively
26 modulation and coding rate of the reception quality information set according to the predetermined table as shown in Fig. 13. Then, let MaxR, MinR (if the Mo symbol rate and Co coding rate are used) and ConR be the minimum value, maximum value, and retained amount of information, respectively, in which the reception quality information can be mapped, which are set by RRC signaling with base station devices. Here, the minimum value, maximum value, and retained value of the resources in which the reception quality information can be mapped are set as the amount of reception quality information, e.g. the resources can be set with the number of modulation symbols or the number of resource elements for mapping quality information reception before mapping reception quality information to resource items.
[0108] First, the information enhancing type of the mapping method may be determined by the following equation. The Mc symbol rate for the modulation scheme and the Cc coding rate of the reception quality information may be defined as a function of the Md symbol rate and the Cd coding rate for the uplink data and predetermined by the table based on the specification and so on as shown in Fig. 13:
(Mc, Cc) = f (Md, Cd) [0109] Thus, the number of Nsc modulation symbols used for the reception quality information from the mobile station device can be represented using Mc and Cc as follows:
Nsc = Bc * Mc * 1 / Cc * α [0110] Here, as the information enhancing mapping method type is a mapping method for transmitting information on the quality of reception with the amount of information, information on the quality of reception increased in the range of the minimum value and / or the maximum value that are set by RRC signaling from a base station device, Bc can be defined as follows:
Bc = MAXMIN (MaxR, MinR * Nrb * Mc * 1 / Cc * 1 / Mo * Co, MinR) [0111] Thus, the number of Nds modulation symbols used for the uplink data can be represented as follows:
Nds = Nrb * 168 - Ncs - γ
[0112] Where α, β, γ are coefficients and change with other factors, such as the number of reference symbols contained in resource blocks or spread coefficients used for information, etc.
[0113] Next, the information retaining type of the mapping method may be defined by the following equation. The Mc symbol rate for the modulation scheme and the Cc coding rate of the reception quality information may be defined as a function of the Md symbol rate and the Cd coding rate for the uplink data and determined in advance by the table as shown in Fig. 13:
(Mc, Cc) = f (Md, Cd) [0114] Thus, the number of Ncs modulation symbols used for the reception quality information from the mobile station device can be represented using Mc and Cc as follows:
Nsc = ConR * Mc * 1 / Cc * β [0115] Here, as the information-retaining mapping method type is a mapping method for transmitting information on the reception quality with a certain amount of information, information on the reception quality by a stored value that is set by signaling RRC from a base station device, Bc can be defined as follows:
BC = ConR [0116] Thus, the number of Nds modulation symbols used for the uplink data can be represented as follows:
Nds = Nrb * 168 - Ncs - γ where α, β, γ are coefficients and change with other factors, such as the number of reference symbols contained in resource blocks or spread coefficients used for information, etc.
[0117] In this way, the base station apparatus transmits RRC signaling containing information indicating a minimum amount and / or a maximum amount of resources at which reception quality information can be mapped. After receiving the signal, the mobile station device changes the mapping of the uplink data and the reception quality information and simultaneously transmits it. Same, even when resources to
- 28 transmission of reception quality information calculated on the basis of L1 / L2 allocation is larger (i.e. when uplink data having a larger amount of information is transmitted), transmission of link quality information with a certain amount or more (i.e. information about the quality of reception having too much information) by the mobile station device and a significant increase in uplink load caused by the transmission of information about the quality of reception can be avoided. Also, even when the resources for transmitting reception quality information calculated based on L1 / L2 allocation are smaller (i.e. when uplink data having a smaller amount of information is transmitted), the mobile station device may transmit the reception quality information with some or more (the reception quality information set by the minimum amount) and the quality of the reception quality information may be maintained above a certain level. In addition, by setting a minimum amount that can be calculated based on the allocation of L1 / L2 as the minimum amount, you can avoid the transmission of reception quality information that falls below the minimum amount by the mobile station device. Here, by defining the equation for the resources for transmitting information on the quality of reception so that it does not exceed the maximum quantity and that it does not fall below the minimum quantity, each of which can be calculated based on the allocation of L1 / L2, the maximum quantity or minimum quantity must be set at using RRC signaling.
[0118] Also, the base station apparatus transmits RRC signaling containing information indicating a stored resource value at which reception quality information can be mapped. After receiving the signal, the mobile station device simultaneously transmits uplink data and a certain amount of information about the quality of the reception. Hereby, the mobile station device may transmit a certain amount of reception quality information regardless of the resources allocated by L1 / L2 allocation.
[0119] Also, by a mobile station device using the information-retaining mapping method type in transmitting uplink data and periodic reception quality information, a certain amount of reception quality information may be periodically transmitted to the base station device. Meanwhile, by the base station device using the information-enhancing mapping method type in transmitting the uplink data and the aperiodic reception quality information, the reception quality information that applies to resources allocated by L1 / L2 allocation can be transmitted by the base station device.
[0120] According to the first and second embodiments of the invention described above, the base station device may transmit control information to determine the transmission format (resource information (mapping to resource element) and / or modulation scheme and / or coding rate) information (uplink data and / or reception quality information and / or HARQ ACK / NACK) transmitted on the uplink, while the mobile station device may transmit to the base station device information on the uplink based on the transmission format determined by the base station device.
