Mobile communication system, method and mobile station device

Technical Field The invention relates to a mobile communication system in which a mobile station device measures the reception quality of signals received from a base station device and transmits the reception quality information to the base station device while the base station device allocates resources based on quality information. reception of the mobile station received from the device, and relates to the base station device and the mobile station device which are used in the mobile communication system.

Background Art [0002] Recently, a need for data communication has been growing in the field of mobile communication systems. As such, different techniques for better frequency application have been proposed to adapt to the increasing data communication caused by the demand for data transmission. One of the techniques to improve the frequency application is orthogonal frequency division multiple access (OFDMA). OFDMA refers to the modulation method for cells in the communication area consisting of cells for their communication with each other using the same frequency and can perform faster data communication.

[0003] Regarding the scheduling of transmission packets in the OFDMA system, it is well known how the mobile station devices transmit a channel quality indicator (CQI) to the base station device which is information indicative of the quality of the link state reception. descending 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 of the mobile station devices.

Furthermore, a technique is also well known in which, for scheduling transmission packets in an orthogonal frequency division multiplexing (OFDM) system using multiple subcarriers, mobile station devices evaluate the status of each downlink channel (frequency response, this is frequency dependent transmission loss characteristic) and transmits, to the base station device, information acquired by quantizing the states of each channel, while the base station device determines the subcarriers to be assigned to each of the mobile station devices based on the transmitted information (patent document 1).

[0005] Fig. 14 illustrates a method of prior art communication between a base station device and a mobile station device. After receiving the downlink information used to measure the reception quality from the base station device, the mobile station device measures the reception 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 information about the reception quality using the uplink. On the basis of the reception quality information, the base station apparatus performs adaptive modulation and coding or frequency-dependent scheduling for signals to be transmitted from the base station device to the mobile station device.

[0007] In the case of transmission of reception quality information to a base station device by a mobile station device, in a developed universal terrestrial radio access network tested under the Third generation partnership project (3GPP), which is an international standardization project, it is investigated that the reception quality information is transmitted using a dedicated uplink control channel (physical uplink control channel), hereinafter referred to as "PUCCH"). It is also investigated that uplink data and reception quality information are simultaneously transmitted using the uplink shared channel (physical uplink shared channel), hereinafter referred to as "PUSCH").

[0008] For example, in a non-patent document 1, a transmission method is proposed for transmitting reception quality information from a mobile station device to a base station device, reception quality information using PUCCH or PUSCH depending on the type of services different in the requested quality information. reception.

Non-patent document HUAWEI "Further considerations on the multiplexing method of Shared Control Channel in Uplink Single-Carrier FDMA", QUOTING ON THE INTERNET, 11 November 2005 (2005-11-11), R1-051430, describes a method of multiplexing a shared control channel in a single carrier FDMA an uplink in which the signaling of the physical layer for the uplink is divided into two categories: data dependent signaling and signaling independent of the data. For example, information about the reception quality is signaled independently of the data. The signaling independent of the data is the time multiplexed in a predetermined time-frequency limit.

Problems to solve

[0009] However, the prior art does not have specific descriptions for mapping relevant information in the simultaneous transmission of uplink data and reception quality information from a mobile station device to a base station device.

[0010] As used herein, the phrase "mapping relevant information" refers to a specific mapping of relevant information (uplink data and reception quality information) as transmission data, i.e. their respective mapping on a PUSCH resource unit (minimum unit of PUSCH time-frequency block) during simultaneous transmission of uplink data and reception quality information from the mobile station device to the base station device.

[0011] In the case where the uplink data and the reception quality information are simultaneously transmitted from the mobile station device to the base station apparatus, the base station apparatus can separate the respective data by recognizing uplink data mapping and reception quality information. The base station apparatus can extract reception quality information from simultaneously transmitted uplink data and reception quality information, and efficiently transmit uplink data by performing adaptive modulation and frequency dependent coding and / or scheduling based on the extracted information.

[0012] The amount of information of the control signals transmitted from the base station apparatus for determining uplink data mapping and reception quality information simultaneously transmitted from the mobile station device must be small. Downlink resources would be used inefficiently if the base station device would transmit control signals to determine the mapping of the respective information each time during the transmission of the reception quality information from the mobile station device.

[0013] Furthermore, there is an additional need to limit any delay in changing the uplink data mapping and reception quality information simultaneously transmitted from the mobile station device. If there is any significant delay in changing the mapping of relevant information in the simultaneous transmission of uplink data and reception quality information from the mobile station device, another significant delay could occur until the reception quality information reaches the base station device. The base station apparatus uses adaptive modulation and coding and / or frequency dependent scheduling to downlink data based on the reception quality information transmitted from the mobile station device.

[0014] If there is any significant delay in transmitting the reception quality information, the modulation and coding and frequency band used for the uplink data transmission most appropriate for the mobile station device will change. Even if the base station device performs adaptive modulation and coding and / or frequency dependent scheduling based on the reception quality information with a significant delay, it will fail to control the mobile station device in a manner appropriate to the

- mobile station equipment at this point in time. This will result in ineffective use of downlink resources.

[0015] Furthermore, the modulation scheme and coding rate to be determined in the uplink data transmission are determined by the base station device evaluating the propagation path environment based on uplink data or reference signal transmitted from the mobile station device. For this reason, in the event that uplink data and reception quality information are simultaneously transmitted, if the modulation scheme and the coding rate of the reception quality information can not be compatible with those associated with the uplink data determined by the base station device, the probability of successful transmission will decrease. information about the quality of reception.

Disclosure of the Invention [0016] The above description also relates to an ACK / NACK of hybrid automatic repeat request (HARQ) for downlink data that is also uplink information, as is reception quality information. This is the amount of information of the control signals transmitted from the base station apparatus to determine uplink data mapping and ACK / NACK transmitted simultaneously from the mobile station device to the base station device must be small. In addition, the delay in changing the mapping must be small. Also, the modulation scheme and the ACK / NACK encoding rate simultaneously transmitted with uplink data must match those relating to uplink data defined by the base station device.

[0017] In summary, it is important to determine how to simultaneously transmit uplink and ACK / NACK data from a mobile station device to a base station device. For addressing the problem, it is necessary to take the amount of control information information to determine the mapping of relevant information from the base station apparatus, the delay occurring in changing the mapping of relevant information, and compliance with the modulation scheme and coding rate of the uplink data determined by the base station.

The invention has been prepared from the point of view of these circumstances and provides a mobile communication system, a base station device and a mobile station device that can limit the amount of control information for determining the transmission method for simultaneous transmission of uplink and ACK / NACK data, limiting the delay occurring in changing the method of transmitting and executing uplink data mapping and ACK / NACK, according to the modulation scheme and uplink data rate coding determined by the base station device.

FIRST EMPLOYION EXAMPLE [0029] First, a mobile communication system according to the first embodiment of the invention will be described. The mobile communication system includes a base station device and a mobile station device. Fig. 1 is a block diagram showing a schematic

Configuring the base station apparatus according to the first embodiment of the invention. The base station apparatus 100 includes a data control unit 101, a modulation coding unit 102, a mapping unit 103, a 104 Inverse fast Fourier transformation unit (IFFT), a radio transmission unit 105, a receiving 106 radio unit 107, a fast transform unit 107. Fourier (Fast Fourier transformation, FFT), decoding demodulation unit 108, data extraction unit 109, scheduling unit 110, transmission information control unit 111 and antenna 112. Transmission information control unit 111 includes a unit 111a controlling the modulation coding and the 111b unit. serializing depending on the frequency.

[0030] The transmission data to be transmitted to each mobile station device and control data is provided to the input of the data control unit 101 in the base station apparatus 100, and each data is transmitted sequentially to the mobile station devices in accordance with the instructions of the scheduler unit 110. The modulation coding unit 102 applies modulation and correction coding to the signals supplied from the data control unit 101 based on the modulation scheme and coding rates determined by the modulation coding unit 111a, and sends each data to the mapping unit 103. The mapping unit 103 maps the input data from the modulation coding unit 102 to each subcarrier based on the frequency-dependent scheduling information provided by the scheduler 111b and sends each data to the IFFT unit 104.

[0031] The IFFT unit 104 applies the inverse fast Fourier transform to the input data from the mapping unit 103, then converts the input data to the temporary digital baseband signals and finally sends the signals to the transmit radio unit 105. In the radio transmission unit 105 transmitting to the signals sent from the IFFT unit 104, a digital-to-analog conversion is used, and the resulting signals then have a frequency up to a frequency suitable for transmission and are transmitted to each mobile station device via the antenna 112.

[0032] The scheduler 110 performs both downlink and uplink scheduling based on control information, such as resource areas available for each mobile station device, intermittent transmission / reception cycles, data channel format, and buffer state. The modulation coding unit 111a determines the modulation scheme and code rate to apply 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 frequency-determining entity 111b applies frequency-dependent scheduling to each data based on the reception quality information transmitted from the mobile station device and outputs the result to the mapping unit 103.

[0033] Fig. 2 is a block diagram showing a schematic configuration of a mobile station device according to the first embodiment of the invention. The mobile station device 200 includes a data control unit 201, a modulation coding unit 202, a mapping unit 203, an inverse fast instant transform (204) unit 204, a radio transmission unit 205, a receiving radio unit 206, a unit 207.

- Fast Fourier Transform (FFT), decode demodulation unit 208, data mining unit 209, reception quality information control unit 210 and antenna 211. Receive quality information control unit 210 includes a control unit 210a generating reception quality information and a quality measurement unit 210b. reception. It is to be noted here that the receiving unit comprises a radio receiving unit 206, an FFT unit 207, a decoding demodulation unit 208, a data mining unit 209, and a reception quality control information unit 210, while the transmitting unit comprises a data control unit 201, a modulation coding unit 202, a mapping unit 203, a fast reverse Fourier transform unit 204 (IFFT) and a transmitting radio transmission unit 205.

[0034] The transmission data to be transmitted to the base station apparatus and control data is provided to the input of the data control unit 201 in the mobile station device 200, and the data is transmitted sequentially to the base station device. The modulation coding unit 202 applies modulation and correction coding to the signals fed from the data control unit 201 and sends each data to the mapping unit 203. The mapping unit 203 maps the input data from the modulation coding unit 202 to each subcarrier and sends each data to the IFFT unit 204.

[0035] The IFFT unit 204 applies the inverse fast Fourier transform to the sequence of input symbols from the mapping unit 203, converts it to the temporary digital baseband signals and sends it to the transmit radio unit 205. In a radio transmission unit 205 transmitting to signals sent from the IFFT unit 124, a digital-to-analog conversion is used, and the resultant signals then have a frequency up to a frequency suitable for transmission and are then transmitted to the base station apparatus via antenna 211.

[0036] The reception quality measurement unit 210b of the reception quality information control unit 210 measures the reception quality of signals received from the base station apparatus. The reception quality information unit 210a generates reception quality information for transmission to the base station apparatus based on the information measured by the unit 210b of reception quality measurements.

The receiving unit comprising the receiving radio unit 206, the FFT entity 208, the decoding demodulation unit 208, the data mining unit 209, and the reception quality information control unit 210 receives the reception quality information from the base station apparatus for determining the transmission format of the information to be transmitted at using uplink and based on a specific format, it recognizes the transmission format for transmitting uplink data and reception quality information, as well as uplink and ACK / NACK data.

[0038] The transmitting unit comprising the data control unit 201, the modulation coding unit 202, the mapping unit 203, the IFFT unit 204 and the transmitting radio unit 205, simultaneously transmits, to the base station device, link data.

- 10 as well as information on the reception quality, as well as the uplink and ACK / NACK data in the transmission format recognized by the receiving unit.

[0039] Fig. 3 illustrates exemplary mapping of uplink data and reception quality information transmitted from a mobile station device to a base station device according to the first embodiment of the invention. Fig. 3 shows Fig. 1 and Fig. 2. For each embodiment, the vertical direction represents the timeline and here includes fourteen OFDM symbols as an example of resources allocated by the base station apparatus. Many known reference symbols (pilot signals, hereinafter "RSs") used to estimate the propagation path for demodulation of data, a different amount of reception quality information and uplink data between form 1 and form 2 are mapped to these fourteen OFDM symbols.

[0040] On the other hand, the horizontal direction represents the frequency axis. Assuming a PUSCH resource unit (minimum PUSCH time-frequency block unit) as one resource block, the base station device in the direction of the frequency axis allocates resources of one resource block in form 1 and two resource blocks in form 2.

[0041] The mobile station device transmits data from the base station apparatus via PUSCH according to the resource allocation defined by the downlink control channel (physical down- wise control channel), hereinafter "PDCCH"). In other words, the downlink control channel (PDCCH) signals for allowing data transmission in the uplink (i.e., allocation L1 / L2).

[0042] In an embodiment, the mobile station device performs information mapping in simultaneous uplink data transmission and reception quality information according to the resources allocated by the base station apparatus using the L1 / L2 grant.

[0043] More specifically, the embodiment 1 of Fig. 3 shows that the mobile station device is allocated, using the L1 / L2 grant from the base station apparatus, resources in fourteen OFDM symbols in the direction of the time axis and one resource block in the direction of the frequency axis, and performs uplink data mapping and reception quality information associated with allocated resources. Here, an element consisting of one OFDM symbol and one subcarrier is called a "resource element". In this example, if one resource block consisting 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.

Similarly, embodiment 2 of Fig. 3 shows that the mobile station device is allocated, using the allocation L1 / L2 from the base station apparatus, resources with fourteen OFDM symbols in the direction of the time axis and two resource blocks in the direction of the frequency axis, and performs uplink data mapping and reception quality information associated with allocated resources.

[0045] Here, it is possible to determine in advance which resource type the base station device allocates using the L1 / L2 allocation and, accordingly, how the mobile station device maps uplink data and reception information. This is, according to the embodiment, determined

It is in advance that in the case where the base station device allocates fourteen OFDM resource resources in the direction of the time axis and one resource block in the direction of the frequency axis, the mobile station device performs uplink data mapping and reception quality information represented by the form. It is likewise also determined in advance that in the case where the base station device allocates resources in fourteen OFDM symbols in the direction of the time axis and two resource blocks in the direction of the frequency axis, the mobile station device performs uplink data mapping and quality information. reception represented by character 2.

[0048] Since, when allocating resources to a mobile station device using L1 / L2 allocation, the base station knows in advance what is the mapping type (e.g. form 1 or character 2) of uplink data and reception information transmitted simultaneously, the base station device can separate uplink data and reception quality information. The base station apparatus may then apply to the uplink data an adaptive modulation and coding and / or frequency dependent scheduling based on the retrieved reception quality information.

[0047] Next, form 1 and embodiment 2 will be described in more detail above as an example of uplink data mapping and reception quality information transmitted simultaneously from a mobile station device to a base station device. Form 1 has more information about the quality of reception in the direction of the timeline (including the fourteen OFDM symbols here). In this embodiment, the reception quality information transmitted from the mobile station device to the base station device is mapped so as to be more resistant to temporary fluctuations in the propagation path. On the other hand, figure 2 has more information about the quality of reception in the direction of the frequency axis. In this embodiment, the reception quality information transmitted from the mobile station device to the base station device is mapped so that

[0048] Similarly, Fig. 4 illustrates further exemplary 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 that of Figure 1 is shown. Figure 3 of Figure 4 shows that the reception quality information can be simply mapped at a lower (or higher) frequency for the resources allocated by the base station device. With this simple mapping, the base station apparatus can separate the uplink data from the reception quality information without performing any complicated process.

[0049] Similarly, FIG. 5 shows further exemplary uplink data mapping 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 form 4 similar to the form 1 of Fig. 3 is shown. Form 4 is significantly different from Form 1 in that the reception quality information is mapped in the direction of the frequency axis in a distributed manner and in that the uplink data is inserted. in a place where information about the quality of reception was available. Each region for reception quality information consists of groups of one or more resource elements. In addition, as shown in the embodiment 5 of Fig. 5, by mapping

Information about the quality of reception in the direction of the frequency axis in a distributed manner can be achieved more resistant to frequency variations in the propagation path, while using resources of the same size as in the form 4 for transmission of reception quality information (although for one OFDM symbol in form 4, groups of four resource elements are used, and in the form of a group of two resource elements, the size of the form is the same, because the last character uses two resource blocks in the direction of the frequency axis).

[0050] Furthermore, FIGS. 6 to 8 show exemplary uplink data mapping and reception quality information transmitted from a mobile station device according to the first embodiment of the invention. These figures are substantially different from FIGS. 3 to 5 in that in each embodiment uplink data mapping and reception quality information is shown with a gradation pattern. The figures shown on the left of FIGS. 6 to 8 are shown as a form 1 'associated with the embodiment 1 shown in FIG. 3.

[0051] In FIGS. 6 to 8, conceptually, the gradation patterns show that uplink data and reception quality information are mapped equally in one resource element. In particular, they are mixed before they are mapped to the resource element. In these figures, the black part and the white part of the gradation pattern indicate, respectively, information on the reception quality and the uplink data. The uplink data and the reception quality information are mixed before mapping to a resource element and then mapped to, for example, twelve resource elements. This is, conceptually, one resource element contains part of the reception quality information and a portion of the uplink data.

[0052] The form 1 'of Fig. 6 shows the mapping of uplink data and reception quality information in case one resource block is defined by the allocation L1 / L2. In the 1 'form, uplink data and reception quality information are mapped mixed into four OFDM symbols from fourteen OFDM symbols. On the other hand, the embodiment 6 of Fig. 6 shows the mapping of uplink data and reception quality information in case two resource blocks are determined by the allocation L1 / L2. In form 6, in four OFDM symbols of fourteen OFDM symbols, uplink data and reception quality information are mapped as resources transmitted in a mixed manner and further mapped using two resource blocks in the frequency direction. Figure 6 of Figure 6 is a form that has been mapped so that the amount of information on the reception quality can be increased as the number of allocated resource blocks increases. In addition, in the case of form 1 'and form 6, the black portion representing the quality of the reception with gradation is shown with the same density. This indicates that the uplink data relations and reception quality information mixed together in the form of 1 'and in form 6 are the same.

[0053] Form 1 'of Fig. 7 is similar to Fig. 1 in Fig. 6. Furthermore, Fig. 7 shows, similarly to Form 6 of Fig. 6, uplink data mapping and reception quality information in the case of two blocks. resources are determined by the L1 / L2 allocation. In form 7, in two OFDM symbols of fourteen OFDM symbols, uplink data and reception quality information are mixedly mapped as resources transmitted and further mapped using two resource blocks in the frequency direction. Hence

- Figure 7 is a figure that has been mapped so that the amount of reception quality information can not increase as the number of allocated resource blocks increases. In addition, in the case of the 1 'and the form 7, the black part showing the quality of the reception with gradation is presented with the same density, indicating that the ratios of the mixed uplink data and the reception quality information are the same.

[0054] The form 1 'shown in Fig. 8 is similar to the embodiment 1' shown in Fig. 6. Form 1 'and form 8 are substantially different in that each of the black parts in the gradation pattern indicating the reception quality information is represented with different density. For example, the black portion of form 8 has a lower density. This implies that the uplink data relationships and reception quality information mixed in the 1 'and in the form of 8 are different, and implies that uplink data relations and reception quality information are mixed before mapping to a resource element. In Fig. 8 it is shown that the amount of information about the quality of reception of all information to be transmitted in form 1 and in form 8 is the same.

[0055] Now, details will be described with reference to a more specific example. In the case of the embodiment 1 'of Fig. 8, assuming that the reception quality information in the amount "4" and the uplink data in the amount "6" are mixed in the resource with one symbol and one resource block, in the case of form 8, the quality information collection in the amount of "2" and the uplink data in the amount of "8" would be mixed in such a resource. This is the amount of information about the quality of reception contained in the resource of one symbol and one block of resources becomes smaller. However, compared to form 1 ', character 8 has a double number of resource blocks in which uplink data and reception quality information are mixed for transmission. This is the information about the quality of reception sent in the entire form of the 1 'and these in the entire form 7 have the same amount of information.

[0056] If uplink data and reception quality information such as those shown in Figs. 6 to 8 are mixed before being mapped to resource elements and the base station device receives information mapped in a plurality of resource elements, then the base station device may be constructed as to be able to extract the received information as one integrated information (reception quality information, uplink data) after receiving all distributed resource elements.

[0057] As described above with concept mapping as illustrated in Figures 6 to 8, where uplink data and reception quality information are mixed before mapping to a resource element, the base station apparatus need not specify where the resource element including the uplink data or information on the quality of the reception should be mapped, and can effectively carry out the tasks needed to map information to the element of resources. Such mixing of the uplink data and the reception quality information can be done by, for example, inserting reception quality information for each modulation symbol at the location where the uplink data has occurred, and applying to, for example, a discrete Fourier transform.

[0058] The mobile station device may perform uplink data mapping and reception quality information as shown in Figs. 3 to 8 depending on the resources

-14 allocated by the L1 / L2 grant from the base station device. For more detailed description of Figures 6 to 8, the mobile station device may vary the uplink data rate and the reception quality information to be mixed, depending on the resources allocated by the L1 / L2 grant from the base station apparatus. Briefly, with reference to Fig. 8, the mobile station device may change the density of the black portion indicative of the reception quality depending on the resources allocated by the L1 / L2 grant from the base station apparatus. It should be noted that the information mapping described above is only exemplary, and for example, the mappings shown in Figures 3 to 8 can be combined,

[0059] The method of mapping reception quality information on groups of resource elements described above may be roughly divided into two parts. One is for increasing the amount of information resources in proportion to the resources allocated for the uplink data. For example, as in characters 1, 1 'and 6, in the case where groups of four resource elements are mapped in one resource block as reception quality information, if two resource blocks are allocated, then reception quality information is transmitted in groups of eight. resource elements. The second is for changing the mapping so that the amount of resources (number of resource elements) of the reception quality information can always be fixed, depending on the allocation of resources for the uplink data. An example of this mapping is any mapping in the form of 2, 3, 5, 7 or 8.

[0060] Now, the first and second mapping methods described above are defined as "information-increasing type" and "information-retaining type" respectively. It will also be described how to control each type of mapping method. First, a method for controlling the type increasing information in the base station apparatus will be described. When performing the type mapping increasing the information, the base station apparatus may transmit, to the mobile station device, RRC signaling including information indicating the minimum amount and / or the maximum amount of resources in which the reception quality information can be mapped.

[0061] It should be noted here, for example, that the minimum amount of resources in which the reception quality information can be mapped can be set as the amount of reception quality information resources (e.g. number of modulation symbols, number of resource elements, amount of information and so further), which can be mapped in one block of resources. That is, it is the maximum amount of information about the quality of reception, which can be mapped in one block of resources. In the meantime, the maximum amount of resources at which the reception quality information can be mapped can be set as the maximum amount of reception quality information resources (e.g. number of modulation symbols, number of resource elements, amount of information and so on) that can be mapped in resource blocks allocated by the base station device.

[0062] The mobile station device continues to perform uplink data mapping and reception quality information with the information enhancing type (see characters 1, 1 'and 6) based on the number of resource blocks and / or transport block sizes allocated by the L1 / L2 allocation. before reaching the minimum amount of resources in which information on the reception quality can be mapped (the minimum amount of information about the quality of receipt to be mapped in one resource block) set by signaling the RRC from the base station device.

[0063] Additionally, in case the resources calculated on the basis of the L1 / L2 grant in the reception quality information mapping exceed the maximum amount of resources in which the reception quality information can be mapped, set by signaling the RRC from the base station device, the mobile station device maps uplink data and reception quality information, i.e. the amount of resources does not exceed the maximum amount of resource set by the base station device, by reducing the amount of resources in the time direction for mapping reception quality information as shown in form 7 or by reduction of the uplink data reduction ratio to reduce the resource ratio for mapping the reception quality information, as shown in form 8.

[0064] Furthermore, in the case where the resources calculated on the basis of the L1 / L2 grant in the reception quality information mapping fall below the minimum amount of resources in which the reception quality information set by RRC signaling from the base station device can be mapped, the mobile station device maps uplink data and reception quality information, so that the amount of resources does not fall below the minimum amount set by the base station device, by increasing the amount of resources in the time direction for mapping reception quality information as shown in form 7, or by increasing the uplink data reduction ratio to increase the resource ratio for mapping the reception quality information, as shown in form 8.

[0065] Thus, the base station apparatus transmits RRC signaling including information indicating the minimum amount and / or the maximum amount of resources at which the reception quality information can be mapped. After receiving the signal, the mobile station device changes the uplink data mapping and the reception quality information, and transmits them simultaneously. Hence, even when the resources for transmitting the reception quality information calculated on the basis of the L1 / L2 grant are larger (i.e. when the uplink data is transmitted have a larger amount of information), it is possible to avoid transmitting the reception quality information of a specific or greater quantity (i.e. information about the quality of reception with too much information) by the mobile station device and avoiding a significant increase in the uplink overhead due to the transmission of the reception quality information. Furthermore, when the resources for transmitting the reception quality information calculated on the basis of the L1 / L2 grant are smaller (e.g., when uplink data with less information is transmitted), the mobile station device may transmit reception quality information with a predetermined or larger amount (information about reception quality set by a minimum amount), and the quality of the reception quality information can be maintained above a certain level. also Furthermore, when the resources for transmitting the reception quality information calculated on the basis of the L1 / L2 grant are smaller (e.g., when uplink data with less information is transmitted), the mobile station device may transmit reception quality information with a predetermined or larger amount (information about reception quality set by a minimum amount), and the quality of the reception quality information can be maintained above a certain level. also Furthermore, when the resources for transmitting the reception quality information calculated on the basis of the L1 / L2 grant are smaller (e.g., when uplink data with less information is transmitted), the mobile station device may transmit reception quality information with a predetermined or larger amount (information about reception quality set by a minimum amount), and the quality of the reception quality information can be maintained above a certain level. also

By setting a minimum amount that can be calculated based on the L1 / L2 allocation as the minimum quantity, the transmission of the reception quality information that falls below the minimum amount can be avoided by the mobile station device transmitting. Here, by defining the equation for resources to transmit the reception quality information, which is to not exceed the maximum quantity and is not to fall below the minimum amount, each of which can be calculated on the basis of the L1 / L2 allocation, the maximum quantity or minimum amount does not have to be set using RRC signaling.

[0066] Next, a method for controlling the type that maintains the information of the mapping method in the base station device will be described. When the mobile station device performs the mapping type holding the information, the base station device may transmit, to the mobile station device, RRC signaling including information indicating a given amount (hence the holding value) of the resources in which the reception quality information can be mapped. It should be noted here that the amount of resource maintenance in which the reception quality information can be mapped can be defined as a defined number of resources (e.g., number of modulation symbols, number of resource elements, amount of information, and so on) of reception quality information that can be be mapped in resource blocks allocated by the base station.

[0067] In addition, in the case that the amount of resources calculated in the reception quality information mapping exceeds the amount of resource retention in which the reception quality information can be mapped, set by signaling the RRC from the base station device, the mobile station device maps the uplink data and information about the quality of reception, i.e. the amount of resources does not exceed the amount of holding set by the base station, by reducing the amount of resources in the time direction for mapping reception quality information as shown in form 7 or by reducing the uplink data reduction ratio to reduce the proportion of the amount of resources for mapping the reception quality information, as shown in form 8.

[0068] Furthermore, in the case where the amount of resources calculated in the reception quality information mapping falls below the amount of holding resources in which the reception quality information set by RRC signaling from the base station device can be mapped, the mobile station device maps the uplink data and information. about the quality of reception, i.e. the amount of resources does not fall below the amount of holding set by the base station device, by increasing the amount of resources in the time direction for mapping reception quality information as shown in form 7, or by increasing the data reduction ratio uplink to increase the amount of resources for reception quality information, as shown in form 8.

[0069] Thus, the base station apparatus transmits RRC signaling containing information (hold value) indicating a given amount of resources in which the reception quality information can be mapped. After receiving the signal the device of the mobile station

- simultaneously transmits uplink data and a certain amount of information about the quality of reception. Hence, the mobile station device may transmit a specific amount of reception quality information regardless of the resources allocated by the L1 / L2 allocation.

[0070] Fig. 9 shows a sequence network of operations of a base station device and a mobile station device according to the first embodiment of the invention. First, the base station device allocates resources for the mobile station device for the uplink data transmission (step S61) by means of the allocation L1 / L2. Here, it is assumed that resources are allocated according to the embodiment 1 of Fig. 3. Then, after receiving the L1 / L2 grant from the base station device, the mobile station device simultaneously transmits uplink data and reception quality information with information mapping (here from form 1). ) related to allocated resources (S62).

[0071] Next, the base station device reallocates resources for the mobile station device for the uplink data transmission (S63) by means of the L1 / L2 grant. Here, it is assumed that the resources are allocated according to the form 2 in Fig. 3. Then, after receiving the allocation L1 / L2 from the base station apparatus, the mobile station device simultaneously transmits uplink data and reception quality information with the information mapping (here from form 2) associated with the allocated resources (S64). Here, uplink data mapping and reception quality information associated with resources allocated by the base station device using the L1 / L2 grant can be predetermined.

[0072] As described above, by predetermining uplink data mapping and reception quality information according to the allocation of uplink data resources from the base station apparatus and by the mobile station device performing the uplink data mapping and reception quality information according to the allocation of resources uplink data from the base station apparatus, there is no need to transmit control signals to determine the mapping of the relevant information. As a result, you can limit the inefficient use of downlink resources. In addition, because information mapping in the simultaneous transmission of uplink data and reception quality information is changed in accordance with the method of allocation of uplink resources,

[0073] According to a first embodiment, the base station apparatus allocates resources for uplink data. However, due to the mapping of reception quality information transmitted simultaneously with uplink data in accordance with this resource allocation, as a result, the base station device allocates resources for uplink data and reception quality information.

[0074] The first embodiment of the invention described above can be used when uplink data and ACK / NACK data are transmitted simultaneously. That is, by predetermining the uplink and ACK / NACK data mapping according to the allocation of uplink data resources from the base station device, and by implementing by

The device of the mobile uplink data mapping station and ACK / NACK according to the allocation of the uplink data resources from the base station device, no control signals are needed to determine the mapping of the relevant information (uplink data and ACK / NACK). As a result, you can limit the inefficient use of downlink resources. In addition, since the mapping of information in simultaneous uplink and ACK / NACK data transmission is changed in accordance with the method for allocating uplink resources, no control signals are needed to change the mapping of relevant information and the delay in changing the mapping of relevant information can be reduced.

SECOND EMPLOYABILITY [0075] According to a second embodiment, a mobile station device determines a modulation scheme and coding rate to be applied to simultaneously transmitted reception quality information based on a modulation scheme and coding rates applied to uplink data allocated by a base station device via the L1 allocation. L2.

[0076] The base station device allocates resources for uplink data using the L1 / L2 grant and determines the modulation scheme and coding rate applied to the uplink data. Upon receipt of this signal, the mobile station device determines a modulation scheme and coding rate to apply to the reception quality information based on those used for the uplink data. It should be noted that the modulation scheme and code rate are applied to the uplink data by the base station device using the L1 / L2 allocation, and those used for the reception quality information by the mobile station device can be predetermined.

[0077] Fig. 10 shows the content of a predetermined table in a mobile communication system according to a second embodiment of the invention. As shown in Fig. 10, the modulation scheme and code rate to be applied to the uplink data by the base station device are associated with those to be applied to the reception quality information. As shown in Fig. 10, it has been predetermined that in the case where the base station apparatus determines the use of the QPSK modulation scheme and coding rates 1/8 for the uplink data, the mobile station device uses a QPSK or BPSK modulation scheme and coding rate 1 / 8 or 1/16 for information on the reception quality for transmission. Furthermore, for example, it is pre-determined that in the case of

[0078] This is, for example, due to the base station determining the 16QAM modulation scheme and the 1/4 coding rate for the uplink data, the uplink data for which the 16QAM modulation scheme and the coding rate are used.

1/4 and information on the reception quality for which the 16QAM or. Modulation scheme is used

-19QPSK and the coding rate 1/4 or 1/8 are simultaneously transmitted from the mobile station device. It should be noted that the coding rate used for the uplink data and the coding rate used for the reception quality information can be calculated from the modulation scheme and the size of the transport block to be transmitted. This is the modulation scheme and the transport blocks to be transmitted can be predetermined.

[0079] This relationship between the modulation scheme and the rate of uplink data encoding and those of the reception quality information can be mapped in advance one to one or one to many. For one-to-many mapping, blind decoding will be used with multiple modulation schemes and coding rates associated with the modulation scheme and coding rate of the uplink data in demodulating the reception quality information in the base station apparatus.

[0080] In general, when a high modulation scheme and 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 coding rate are used, high reliability information may be transmitted. As described above, by determining the modulation scheme and coding rates applied to the reception quality information associated with those used for the uplink data by the base station device, the modulation scheme and coding rate of the reception quality information transmitted simultaneously with the uplink data may be consistent with those for uplink data, which increases the probability of successful transmission of reception quality information.

When a mobile station determines a modulation scheme and coding rate to be used for uplink data using the L1 / L2 grant, the base station apparatus may decode the corresponding information based on a modulation scheme and coding rate of reception quality information because the base station device knows advance modulation scheme and coding rate of reception quality information transmitted simultaneously with uplink data. It should be noted here that in the case where the link between the modulation scheme and the uplink data rate and the reception quality information is mapped in a one-to-many manner, decoding will be made for all possible modulation schemes and coding rates (blind decoding) . and then the results will be checked using a cyclic redundancy check (CRC) for correct modulation. The base station apparatus uses adaptive modulation and coding and / or frequency dependent scheduling to downlink data based on correctly demodulated reception quality information.

[0082] Fig. 11 shows a sequence network of operations of a base station device and a mobile station device according to a second embodiment of the invention. First, the base station device determines, using the L1 / L2 grant, the modulation scheme and coding rate applied to the uplink data (step S71). Here, it is assumed that modulation scheme A and coding rate B are defined as the modulation scheme and coding rate applied to the uplink data. Then, after receiving the assignment L1 / L2 from

- base station apparatus, the mobile station device applies to the reception quality information a modulation scheme and coding rate associated with the modulation scheme A and the coding rate B. Here, it is assumed that the modulation scheme C and coding rate D are applied to the reception quality information associated respectively with the modulation scheme A and the coding rate B. Then, the mobile station device simultaneously transmits, to the base station apparatus, uplink data to which modulation scheme A and coding rate B and reception quality information to which the modulation scheme C is applied. and coding rate D (step S72).

[0083] Next, the base station apparatus again determines, using the L1 / L2 grant, the modulation scheme and coding rate applied to the uplink data (step S73). Here, it is assumed that the modulation scheme E and the coding rate F are defined as the modulation scheme and coding rate applied to the uplink data. Then, after receiving the L1 / L2 grant from the base station apparatus, the mobile station device applies to the reception quality information a modulation scheme and coding rate associated with the modulation scheme E and the coding rate F. Here, it is assumed 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 device simultaneously transmits to the base station device, uplink data to which modulation scheme E and coding rate F and reception quality information are applied, to which modulation scheme C and coding rate D (step S74) are applied. Here, the modulation scheme and coding rate of the reception quality information associated with those applied to the uplink data by the base station device using the L1 / L2 grant are predetermined.

[0084] As described above, the modulation scheme and coding rate of the reception quality information transmitted simultaneously with the uplink data are predetermined in accordance with those applied to the uplink data determined by the base station device, and the mobile station device may use a modulation scheme and rate coding for reception 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 apparatus may be in accordance with the modulation scheme and the uplink data rate coding, which increases the probability of successful transmission of reception quality information.

[0085] According to a second embodiment, the base station apparatus determines a modulation scheme and a coded rate for use in uplink data. However, as the modulation scheme and coded rate of the reception quality information transmitted simultaneously with the uplink data can also be determined accordingly, as a result the base station device determines the modulation scheme and coded rate of uplink data and reception quality information.

[0086] The second embodiment of the invention described above can also be used when uplink data and ACK / NACK data are transmitted simultaneously. This is thanks

Determining a modulation scheme and coding rates ACK / NACK transmitted simultaneously with uplink data in accordance with the definition of those to be used for uplink data from the base station apparatus and by using the mobile station device the modulation scheme and code rate to ACK / NACK according to the term for those applied to the uplink data from the base station device, ACK / NACK, transmitted from the mobile station device to the base station device may be compatible with the modulation scheme and coding rate of the uplink data, which increases the probability of successful transmission of the reception quality information.

THIRD EXAMPLE OF EMBODIMENTS [0087] Considering the first and second embodiments described above, a specific operating example of the base station device and the mobile station device will be described as a third embodiment. Fig. 12 shows the L1 / L2 grant transmitted from the base station device to the mobile station device, non-periodic reception quality information transmitted, periodic reception quality information, uplink data from the mobile station device to the base station device, and transmission form for simultaneous transmission uplink data or uplink data and reception quality information. Periodic transmission of reception quality information from a mobile station device to a base station device can be achieved, for example, by transmitting a base L1 / L2 assignment comprising one-bit information via the base station device, thanks to the mobile station device transmitting the reception quality information to the base station device after receiving the signal. In the meantime, the non-period transmission of reception quality information from the mobile station device to the base station device may be achieved, for example, by transmitting a RRC signaling station by the device including information setting periodicity for transmitting the reception quality information from the base station device to the mobile station device, by transmitting by the mobile station device information about the reception quality with the set periodicity to the base station device after receiving the signal. Fig. 12 shows, by way of example, the action of slots 1 to 10. In addition, on the right-hand side of Fig. 12 is shown a network of processing operations for each slot. In this figure, for the sake of clarity of the processing flow network, only some arrows are shown, i.e. the slot 1 arrow shows the processing flow network from the base station apparatus and the remaining arrows for the other slots represent the processing flow network from the mobile station device, which will be described in more detail below.

[0088] Fig. 13 shows a predetermined table of modulation schemes and coding rates used in the third embodiment. The mobile station device for which the modulation scheme and the baud rate are determined for the uplink data by the L1 / L2 grant from the base station apparatus, apply the modulation scheme and the coding rate to the reception quality information by using the table defined in Figure 13. For example, if the base station device will determine the QPSK modulation scheme and the coding rate of 1/8 of the uplink data, then the mobile station device for the reception quality information uses a BPSK modulation scheme and a coding rate of 1/4.

[0089] Turning back to Fig. 12, the operations of each slot will be described. The base station apparatus transmits RRC signaling including a minimum amount and / or a maximum amount and amount of resource retention in which reception quality information can be mapped for simultaneous transmission of uplink data and reception quality information by the mobile station device. For the sake of clarity, the minimum value, maximum value and value of maintaining the information in which the reception quality information can be mapped are set to 10, 50 and 20. Here, these values ​​are set only as an example, a minimum value and / or a maximum value and the value of maintaining resources at which the reception quality information can be mapped can be set, for example, by using the number of modulation symbols, the number of resource elements to map the reception quality information and the amount of information (the number of bits) for the reception quality information before mapping the reception quality information to the resource elements. Furthermore, all of the minimum value and / or the maximum value and holding value are not to be set in the slot 1.

[0090] The slit 2 is a slit that is set in advance by a base station apparatus for periodically transmitting reception quality information. In slot 2, using allocation L1 / L2, the base station device allocates the resources used to transmit the uplink data by the mobile station device. Upon receipt of this signal, the mobile station device transmits both the uplink data and the reception quality information at the same time with the manner of mapping the type retaining the information by using the allocated resources.

[0091] Further, the operation of the mobile station device will be described in the slot 2. In slot 2, the mobile station device transmits, to the base station device, uplink data and reception quality information with the type of information holding mapping method. The information retaining mapping method is a mapping method for transmitting a specific amount of reception quality information with a retention amount set by RRC signaling.

[0092] In particular, here the hold value at which the reception quality information can be mapped is set to by signaling the RRC from the base station apparatus. In this case, by using the L1 / L2 grant, the base station device sets use of one resource block as resources, a QPSK modulation scheme, and a coding rate of 1/8 for transmitting uplink data. Referring to the table shown in Fig. 13, this means the modulation scheme and coding rate of the reception quality information set at BSPK and 1/16 respectively. With this control from the base station device, the mobile station device transmits, using one resource block, uplink data to which the QPSK modulation scheme and coding rate of 1/8 are used, and the reception quality information with size 20, to which the BPSK modulation scheme and the coding rate 1/16 are used. Hence, the amount of resources used for this reception quality information is 320 (i.e. 20 * 1 * 16).

[0093] Furthermore, by using the L1 / L2 grant, the base station device sets the use of two resource blocks as resources, the QPSK modulation scheme and the coding rate 1/8 for

Transmitting uplink data. Referring to the table shown in Fig. 13, this means the modulation scheme and coding rate of the reception quality information set at BSPK and 1/16 respectively. That is, with this control from the base station device, the mobile station device transmits, using two resource blocks, uplink data to which the QPSK modulation scheme and coding rate of 1/8 are used, and reception quality information with size 20, to where the BPSK modulation scheme and the coding rate 1/16 are used. Hence, the amount of resources used for this information on the quality of reception is 320 (e.g., 20 * 1 * 16).

[0094] Furthermore, by using the L1 / L2 grant, the base station device sets use of two resource blocks as resources, a QPSK modulation scheme, and a coding rate of 1/4 for transmitting uplink data. Referring to the table shown in Fig. 13, this means the modulation scheme and coding rate of the reception quality information set at BSPK and 1/8 respectively. That is, with this control from the base station device, the mobile station device transmits, using two resource blocks, uplink data to which the QPSK modulation scheme and coding rate of 1/4 are used, and reception quality information with size 20, to where the BPSK modulation scheme and the coding rate 1/8 are used. Hence, the amount of resources used for this information on the reception quality is 160 (e.g., 20 * 1 * 8).

[0095] The slit 3 is a slit that is set by the base station apparatus to transmit the reception quality information periodically over a period of time. This slot is also set by control from the base station device to transmit the reception quality information in a triggered manner. In slot 3, by using the allocation L1 / L2, the base station device allocates the resources used by the mobile station device for uplink data transmission. Upon receipt of this signal, the mobile station device simultaneously transmits uplink data and reception quality information with a type mapping method for increasing information using the allocated resources.

[0096] Further, the operation of the mobile station device will be described in the slot 3. In slot 3, the mobile station device transmits, to the base station device, uplink data and reception quality information with a type of information-enhancement mapping method. The information-mapping type mapping method is a mapping method for transmission in accordance with the resources allocated by the L1 / L2 grant from the base station apparatus, reception quality information with the amount of resources for mapping the reception quality information increased in the minimum value range and / or the maximum value set by RRC signaling.

[0097] In particular, the minimum value and the maximum value in which the reception quality information can be mapped are set to 10 and 250 by signaling the RRC from the base station apparatus (here the minimum value and the maximum value are set with the BSPK modulation scheme and the rate coding 1/16). In this case, by using the L1 / L2 grant, the base station device sets the use of one resource block as resources, the QPSK modulation scheme, and the coding rate 1/8 for transmitting uplink data. With reference to the table shown in Fig. 13, it means a modulation scheme

And 24a coding rate of reception quality information set to BPSK and 1/16 respectively. With this control from the base station device, the mobile station device transmits, using one resource block, uplink data to which the QPSK modulation scheme and coding rate of 1/8 are used, and reception quality information with size 10 (10 * 1 *) 1 * (1/16) / (1/16)), to which the BPSK modulation scheme and the coding rate 1/16 are used. Hence, the amount of resources used for this information on the reception quality is 160 (e.g., 10 * 1 * 16).

[0098] Furthermore, by using the L1 / L2 grant, the base station apparatus sets use of three resource blocks as resources, a QPSK modulation scheme, and a coding rate of 1/8 for transmitting uplink data. Referring to the table shown in Fig. 13, this means the modulation scheme and coding rate of the reception quality information set at BPSK and 1/16 respectively. That is, with this control from the base station device, the mobile station device transmits, using three resource blocks, uplink data to which the QPSK modulation scheme and coding rate of 1/8 are used, and reception quality information with size 30 (10 * 3 * 1 * (1/16) / (1/16)), to which the BPSK modulation scheme and the coding rate 1/16 are used. Hence, the amount of resources used for this information on the reception quality is 480 (e.g., 30 * 1 * 16).

[0099] Furthermore, by using the L1 / L2 grant, the base station apparatus sets the use of three resource blocks as resources, a 16QAM modulation scheme, and a coding rate of 1/4 for transmitting uplink data. Referring to the table shown in Fig. 13, this means the modulation scheme and coding rate of the reception quality information set at QPSK and 1/4 respectively. That is, with this control from the base station device, the mobile station device transmits, using three resource blocks, uplink data to which the 16QAM modulation scheme and coding rate of 1/4 are used, and reception quality information with 240 (10) * 3 * 2 * (1/4) / (1/16)), to which the QPSK modulation scheme and coding rate 1/4 are used. Hence, the amount of resources used for this information on the reception quality is 480 (e.g., 240 * (1/2) * 4).

[0100] Alternatively, by using the L1 / L2 grant, the base station apparatus sets the use of three resource blocks as resources, a 16QAM modulation scheme, and a coding rate of 1/4 for transmitting uplink data. Referring to the table shown in Fig. 13, this means the modulation scheme and coding rate of the reception quality information set at QPSK and 1/4 respectively. That is, with this control from the base station device, the mobile station device transmits, using three resource blocks, uplink data to which the 16QAM modulation scheme and coding rate of 1/4 are used, and reception quality information with size 30 (10 * 3 * 1 * 1), to which the QPSK modulation scheme and the coding rate 1/4 are used. Hence, the amount of resources used for this information on the quality of reception is 60 (e.g., 30 * (1/2) * 4).

[0101] Furthermore, by using the L1 / L2 grant, the base station device sets the use of four resource blocks as resources, a 16QAM modulation scheme, and a coding rate of 1/4 for transmitting uplink data. Referring to the table shown in Fig. 13, this means the modulation scheme and coding rate of the reception quality information set at QPSK and 1/4 respectively. That is, with this control from the base station device, the mobile station device transmits, using four resource blocks, uplink data to which the 16QAM modulation scheme and coding rate of 1/4 are used, and reception quality information with a size of 320 (10 * 4 * 2 * (1/4) / (1/16)), to which the QPSK modulation scheme and the coding rate 1/4 are used. However, because the maximum value of resources,

[0102] In the slot 4 of Figure 12, the base station apparatus transmits a normal L1 / L2 grant. 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.

[0103] Like slot 2, slot 7 is a slot that is set in advance by the base station apparatus for periodically transmitting reception quality information. In slot 7, using the allocation L1 / L2, the base station device allocates the resources used to transmit the uplink data by the mobile station device. Upon receipt of this signal, the mobile station device simultaneously transmits uplink data and reception quality information with a type mapping method maintaining information using the allocated resources. The type of information retention mapping method is similar to that of slot 2.

[0104] Like the slit 3, the slit 10 is a slit that is set by the base station apparatus to transmit the reception quality information periodically over a period of time. The slot is also set by controlling from the base station apparatus to transmit the reception quality information in a triggered manner. In slot 10, using allocation L1 / L2, the base station device allocates the resources used to transmit the uplink data by the mobile station device. Upon receipt of this signal, the mobile station device simultaneously transmits uplink data and reception quality information with a type mapping method for increasing information using the allocated resources. The type of information-mapping type mapping is similar to that of slot 3.

[0105] Regarding the mapping type of the information retaining information performed in the slots 2 and 7, as well as the mapping type enhancement method implemented in the slots 3 and 10, the amount of information used for the reception quality information and the number of modulation symbols used for the uplink data, for example, it can be calculated in accordance with the following equations. Let Nrb, Md and Bd be the number of resource blocks, the symbol rates for the modulation scheme and the coding rate allocated by the L1 / L2 allocation for transmitting uplink data respectively. Additionally, let Mc and CC

- be the speed of symbols for the modulation scheme and coding rate of the reception quality information, set by means of a predefined table such as that of fig. 13. Furthermore, let MaxR, MinR (if using the Mo symbol speed and coding rate Co) and ConR will be the maximum value, the minimum value and the value of maintaining the amount of information in which the reception quality information set by RRC signaling from the base station apparatus can be mapped. Here, the minimum value, the maximum value and the value of maintaining resources in which the reception quality information can be mapped are set as the amount of information about the reception quality, for example,

[0106] First, the information-enhancement mapping method may be defined by the following equation. The speed of the Mc symbols for the modulation scheme and the coding rate Cc of the reception quality information may be defined as the function of the symbol speed Md and the coding rate Cd for the uplink data, and predetermined by the table based on the description and so on, as shown in FIG. . 13:

Hence, the number of modulation symbols Ncs used for the reception quality information from the mobile station device can be represented using Mc and Cc as follows:

Here, as the information-mapping type mapping method is a mapping method for transmitting reception quality information with the amount of information for reception quality information increased in the minimum value range and / or maximum value that are set by signaling the RRC from the base station device, Bc can be define as follows:

That is, the number of Nds modulation symbols used for the uplink data can be shown as follows:

Where [alpha], [beta], [gamma] are coefficients and change with other factors, such as the number of reference symbols contained in the resource blocks, or spreading factors applied to information, etc.

[0107] Then, the type of information holding mapping method may be defined using the following equation. The speed of the Mc symbols for the modulation scheme and the coding rate Cc of the reception quality information may be defined as functions of the symbol speed Md and the coding rate Cd for the uplink data, and predetermined using a table such as shown in Fig. 13:

Hence, the number of modulation symbols Ncs used for the reception quality information from the mobile station device can be represented using Mc and Cc as follows:

Here, as the information retention mapping method is a mapping method for transmitting reception quality information to a reception value determined by the retention value, which is set by signaling the RRC from the base station apparatus, the Bc can be defined as follows:

That is, the number of Nds modulation symbols used for the uplink data can be shown as follows:

Where [alpha], [beta], [gamma] are coefficients and change with other factors, such as the number of reference symbols contained in the resource blocks, or spreading factors applied to information, etc.

[0108] In the same manner, the base station device transmits RRC signaling including information indicating the minimum amount and / or the maximum amount of resources to which the reception quality information can be mapped. After receiving the signal, the mobile station device changes the uplink data mapping and the reception quality information, and transmits them simultaneously. In this way, even when the resources for transmitting the reception quality information calculated on the basis of the L1 / L2 grant are larger (e.g. when uplink data is transmitted with a greater amount of information), the transmission of a specific or more information on the reception quality can be avoided (e.g. . information about the quality of reception with too much information) by the mobile station device and a significant increase in the uplink overhead due to the transmission of the reception quality information can be avoided. Furthermore, when the resources for transmitting the reception quality information calculated on the basis of the L1 / L2 grant are smaller (i.e. when uplink data with less information is transmitted), the mobile station device may transmit a specific or larger amount of reception quality information (information with reception quality set by the minimum quantity), and the quality of the reception quality information can be maintained above a certain level. In addition, by setting the minimum quantity, which is calculated on the basis of the L1 / L1 allocation as the minimum quantity, it is possible to avoid a drop below the minimum amount of transmission of information on the reception quality by the mobile station device. Here, by defining a resource equation for transmitting reception quality information not exceeding the maximum amount and not falling below the minimum amount, each of which can be calculated on the basis of the L1 / L2 allocation, the maximum amount or the minimum amount does not have to be set using RRC signaling.

[0109] In addition, the base station device transmits RRC signaling including information indicating the holding hold value at which the reception quality information can be mapped. After receiving the signal, the base station device simultaneously transmits uplink data and a certain amount of reception quality information. Hence, the mobile station device may transmit a certain amount of reception quality information regardless of the resources allocated by the L1 / L2 allocation.

[0110] Also, thanks to a mobile station device using a mapping type of the information retaining type during uplink data transmission and reception quality information, a certain amount of reception quality information may be periodically transmitted to the base station apparatus. In the meantime, due to the mobile station application of the type mapping method increasing information during uplink data transmission and non-periodic reception quality information, reception quality information in accordance with the resources allocated by the L1 / L2 grant may be transmitted to the base station device.

[0152] Further, in a mobile station device according to an embodiment, the transmission format of information to be transmitted using an uplink is as for uplink data, and the receiving unit automatically discriminates between the ACK / NACK transmission format and that for uplink data.

Thus, since the mobile station device transmits, to the base station device, together the uplink and ACK / NACK data based on the particular transmission format when the control information is received from the base station device, the base station device can bypass the transmission of any control signals for determining the mapping of relevant information, and it is possible to effectively use downlink resources. In addition, as the transmission format is determined by the method of allocating uplink resources, uplink data mapping and ACK / NACK can be changed, and transmission of control signals can be omitted to change the mapping of relevant information. As a result, the delay in changing the mapping of relevant information can be reduced.

[0155] Thus, in the case where the resource information determined by the frequency component and the temporal component is received from the base station apparatus, a transmission format may be defined for transmitting uplink data and ACK / NACK together. Thus, the base station apparatus may bypass the transmission of any control signals to determine the mapping of relevant information, and it is possible to effectively use downlink resources.

[0156] Furthermore, the mobile station device according to the embodiment, in the case where the receiving unit has received information from the base station device, for determining the modulation scheme and uplink data rate coding as control information, the transmitting unit identifies the modulation scheme and the rate of transmission ACK / NACK which are associated with information for determining the modulation scheme and baud rate for uplink data received from the base station device, and transmits, to the base station device, uplink data to which the modulation scheme and information coding rate are used to determine the modulation scheme and coding rates received from the base station apparatus, together with ACK / NACK, to which the identified modulation scheme and coding rate are used.
