FIG. 2 is a schematic flowchart of a signal transmission method according to an embodiment of the present application, and as shown in FIG. 2, the method 200 includes the following S210 and S220.
In the S210, the network device determines the first setting information, and the first setting information is used to indicate the first time domain resource and the first time domain granularity corresponding to the first time domain resource. The 1-hour domain resource and the 1st time domain granularity are used by the terminal device to search the downlink control channel in the 1st time domain resource with the 1st time domain granularity as a cycle.
In S220, the network device transmits the first setting information to the terminal device.
Specifically, the network device determines the first setting information, and the first setting information is used to indicate the first time domain resource and the first time domain granularity corresponding to the first time domain resource. The network device transmits the first setting information to the terminal device, whereby the terminal device has a first time domain resource and a first time domain resource corresponding to the first time domain resource based on the first setting information. The time domain grain size can be determined, whereby the terminal device searches the downlink control channel (PDCCH, Physical Downlink Control Channel) in the first time domain resource with the first time domain grain size as a cycle. It is possible, or the downlink control channel is searched once for each time domain length of the first time domain granularity, that is, the downlink control channel is searched with the first time domain granularity as an interval.
As an option, the network device may determine the first setting information according to the delay request of the service to be transmitted. For example, if it is not necessary to transmit a service with very low latency in a predetermined period in the future, the network device may set a PDCCH search grain size larger than the first time domain grain size indicated by the first setting information. The terminal device does not need to search the PDCCH too often, whereby the complexity and power consumption of the terminal device searching for the PDCCH can be reduced. Alternatively, when the transmission target service is a low-delay service, the network device can set a PDCCH search grain size smaller than the first time domain grain size indicated by the first setting information, whereby the terminal can be set. The device can increase the frequency of searching for PDCCH, thereby reducing the scheduling delay of the data channel.
As an option, in the embodiment of the present application, the first setting information includes the position information of the first time domain resource and the information of the first time domain granularity corresponding to the first time domain resource, and the first time domain. The location information of the resource is used to indicate the area information in which the terminal device searches for the PDCCH, and the information of the first time domain granularity is the frequency information in which the terminal device searches for the PDCCH, that is, the PDCCH is 1. It is used to indicate the time interval for searching times.
The location information of the first time domain resource may include at least one of a start position, an end position, and a time domain length of the first time domain resource.
For example, the start position of the first time domain resource may be predefined or may be a default value, so that the position information of the first time domain resource is the first time domain resource. The time domain length of the first time domain resource can be determined or the time domain length of the first time domain resource can be defined by including at least one of the end position or the time domain length of the terminal device. It may be, or it may be a default value, so that the location information of the first time domain resource includes at least one of the start position and the end position of the first time domain resource. For example, the terminal device can determine the area in which the PDCCH is searched, or the position information of the first time domain resource is the start position, end position, and time domain length of the first time domain resource. The first time domain resource may be included, that is, the start position and end position of the first time domain resource, or the start position and time domain length, or the end position and time domain length indicate the first time domain resource. The embodiments of the present application do not limit the method indicated by the first time domain resource.
As an option, in the embodiment of the present application, when the position information of the first time domain resource includes the start position or the end position of the first time domain, the start position or end position of the first time domain resource is a synchronization signal. Alternatively, it may be indicated by a time domain position of a sync signal block or broadcast channel, or a time domain offset with respect to a time slot boundary or subframe boundary.
That is, the start position of the first time domain resource is the time domain offset with respect to the time domain position of the synchronization signal, the time domain offset with respect to the time domain position of the broadcast channel, or the time domain offset with respect to the boundary position of a certain time slot. It may be a time domain offset with respect to the boundary position of the subframe, and of course, the start position or end position of the first time domain resource is a time domain offset with reference to another signal, or a time domain offset with respect to the boundary position of a certain symbol. Etc., and the embodiment of the present application does not limit the method in which the start position and the end position of the first time domain resource are indicated.
It should be understood that the above description of the start position or end position of the first time domain resource is merely exemplary and is not intended to limit the present application, and the present application is to future standards such as the first time domain. It does not rule out the possibility of other reference signals with a time domain offset that could be the start or end position of the resource.
It should be noted that the time slot boundary may be a start boundary or an end boundary of a certain time slot, or may be some symbols of the start or some symbols of the end of a certain time slot, and similarly. , The subframe boundary may be the start or end boundary of a subframe, or some symbols at the beginning or some end of a subframe, etc., according to an embodiment of the present application. Does not limit the specific position of the time slot boundary or subframe boundary.
Alternatively, in the embodiments of the present application, the time domain offset is in units of at least one symbol, a predetermined number of symbols, or a time slot, or a mini time slot.
It should be understood that the units of time domain offsets mentioned herein are merely exemplary and are not limiting the present application, and the present application presents new time units in future standards, which are referred to as the time domain. It does not rule out the possibility of using it as a unit of offset.
As an option, in the embodiments of the present application, the first time domain particle size is in units of at least one symbol, a predetermined number of symbols, a time slot, or a mini time slot.
That is, the terminal device may search for the downlink control channel with a predetermined number of symbols as intervals, may search for the downlink control channel with a plurality of time slots as intervals, or may search for the downlink control channel with a plurality of time slots as intervals. The downlink control channel may be searched by using.
It should be understood that the units of the first time domain particle size given herein are exemplary only and are not limiting the present application, and the present application is new to future standards and new time units appear. Does not exclude the possibility that is used as the unit of the first time domain particle size.
In the embodiment of the present application, the first setting information is used to instruct the terminal device to search the PDCCH with the first time domain granularity as a cycle in the first time domain resource, and correspondingly. , The network device transmits PDCCH in a part or all of the first time domain resource with a cycle of the first time domain grain size or a multiple of the first time domain grain size. That is, the time domain resource for the terminal device to search for the PDCCH is greater than or equal to the time domain resource for the network device to transmit the PDCCH, so that it can be ensured that the terminal device can search for the PDCCH transmitted from the network device.
As an option, as an embodiment, the S220 may further include the network device transmitting the first configuration information to the terminal device via upper layer signaling.
Specifically, the upper layer signaling may be radio resource control (RRC, Radio Resource Control) signaling. That is, the network device can semi-statically set the first setting information in the terminal device via upper layer signaling. Then, if the network device is not transmitting other configuration information via upper layer signaling, the terminal device can continue to search for PDCCH based on the first configuration information by default, that is, the first configuration information. In the time domain resource, PDCCH is searched with the first time domain granularity as a cycle.
When the network device intends to change the first setting information set by the semi-static method, the network device can transmit the second setting information to the terminal device via the upper layer signaling, whereby the terminal device can send the second setting information. The second time domain resource and the second time domain granularity can be determined based on the second setting information, and the downlink control channel can be searched based on the second time domain resource and the second time domain granularity. ..
As an option, in the embodiments of the present application, the network device may set the first setting information in the terminal device via downlink control information (DCI, Downlink Control Information), that is, the network device. The first setting information can be dynamically set in the terminal device via DCI. Then, the network device can dynamically adjust the area and frequency in which the terminal device searches for PDCCH via DCI.
For example, the network device can dynamically adjust the area and frequency in which the terminal device searches for PDCCH according to the delay request of the transmission target service, for example, a service with a very low delay in a predetermined period in the future. If there is no need for transmission, the network device can reduce the frequency with which the terminal device searches for PDCCH, for example, by increasing the first time region granularity, the complexity of the terminal device searching for PDCCH and If the power consumption can be reduced, or if it is determined that the network device needs to transmit a low latency service, then the scheduling delay of the data channel needs to be reduced, in which situation the network device is a terminal device. Can increase the frequency of searching for PDCCH, for example, by reducing the first time region granularity, the scheduling delay of the data channel can be reduced.
As an option, in some embodiments, in the method 200, the network device sends second setting information to the terminal device, and the second setting information is in the second time domain within the first time domain resource. It is used to indicate the resource and the second time domain granularity corresponding to the second time domain resource, and the second time domain resource and the second time domain granularity are used by the terminal device to indicate the second time domain resource. In the second time domain granularity, the step used to search the downlink control channel may be further included.
Specifically, when the network device sets the first setting information in the terminal device, the terminal device can search the PDCCH based on the first setting information, that is, in the first time domain resource. Then, the PDCCH is searched with the first time domain particle size as the cycle. If the network device determines within a predetermined time in the future that the terminal device does not need to search for PDCCH frequently, i.e., the terminal device needs to search for PDCCH less frequently, or in the future. If it is determined that the terminal device needs to search the PDCCH more frequently within a predetermined period of time, that is, the terminal device needs to search the PDCCH more frequently, the network device further becomes the terminal device. The second setting information may be transmitted, and the second setting information indicates the second time domain resource in the first time domain resource and the second time domain granularity corresponding to the second time domain resource. Then, the terminal device determines the second time domain resource and the second time domain granularity based on the second setting information, and within the second time domain resource, the second time. PDCCH can be searched with the time domain grain size as the cycle. The second time domain particle size may be larger than the first time domain particle size or smaller than the first time domain particle size, for example, when it is determined that the network device needs to transmit a low latency service. In this situation, the second time domain particle size indicated by the second setting information may be smaller than the first time domain particle size.
Preferably, the second time domain resource is a time domain resource within the first time domain resource, that is, the second time domain resource includes a portion of the time domain resource of the first time domain resource and the terminal. The device searches the PDCCH by the second time domain grain size in the second time domain resource and still by the first time domain grain size in other time domain resources other than the second time domain resource of the first time domain resource. You can search for PDCCH.
As an option, as an embodiment, in the step in which the network device transmits the second setting information to the terminal device, the network device transmits the second setting information to the terminal device via the downlink control information DCI. Including that.
That is, the frequency at which the network device sets the first setting information semi-statically via upper layer signaling and then searches for PDCCH via DCI within a certain period of time of the first time domain resource, that is, It is also possible to flexibly adjust the frequency of searching for PDCCH in the second time domain resource.
For example, if it is not necessary to transmit a very low latency service in a predetermined time in the future, the terminal device may search for PDCCH less frequently, thereby reducing the power consumption of the terminal device, and in this situation, the network. The device can transmit the second setting information to the terminal device, and the second time domain grain size indicated by the second setting information may be larger than the first time domain grain size, that is, the terminal device sets the PDCCH. The frequency of searches is reduced.
Further, for example, when the network device needs to transmit a low-delay service, it can be determined that the terminal device needs to increase the frequency of searching for the PDCCH and reduce the reception delay of the PDCCH. In this situation, the network device can transmit the second setting information to the terminal device, and the second time domain particle size indicated by the second setting information may be smaller than the first time domain particle size, that is, , The frequency with which the terminal device searches for PDCCH increases.
That is, in the network device, the area and frequency for the terminal device to search for PDCCH are set by a semi-static method, and then the area and frequency for the terminal device to search for PDCCH via DCI are flexibly adjusted. You can also.
As an option, in the embodiments of the present application, the network device does not have to transmit the setting information to the terminal device, in which case the network device is based on the predefined third setting information and is a third time domain resource. , And the third time domain grain size corresponding to the third time domain resource, thereby determining the third time domain grain size or the third time domain grain size in some or all of the third time domain resource. PDCCH can be transmitted in multiple cycles.
For the terminal device, the terminal device determines the third time domain resource and the third time domain granularity corresponding to the third time domain resource based on the predefined third setting information, and the third time domain. In the area resource, PDCCH can be searched with the third time domain particle size as a cycle.
As an option, the third setting information may be the setting information promised by the protocol, the setting information defined by the standard, or the default setting information, that is, the terminal device and the network device exchange signaling. The third setting information can be acquired without performing.
When the terminal device searches the PDCCH in the third time domain resource with the third time domain granularity as a cycle, when the terminal device receives the setting information transmitted from the network device, the terminal device receives the setting information transmitted from the network device based on the setting information transmitted from the network device. , The corresponding time domain resource and the time domain grain size are determined, and the PDCCH is searched by the same. For example, when the terminal device searches the PDCCH in the third time domain resource with the third time domain grain size as a cycle. Upon receiving the first setting information transmitted from the network device, the first time domain resource corresponding to the first time domain resource and the first time domain resource is determined based on the first setting information, and the first time domain granularity is determined. In the 1-time domain resource, PDCCH is searched with the 1st time domain granularity as a cycle. The end position of the third time domain resource may be later than the end position of the first time domain resource, may be earlier than the end position of the first time domain resource, and the end position of the third time domain resource may be earlier. If it is later than the end position of the first time domain resource, the terminal device may still search for PDCCH in the third time domain granularity in a region other than the first time domain resource of the third time domain resource. can.
That is, the priority of the setting information transmitted from the network device is higher than the priority of the third setting information, and if the setting information transmitted from the network device is not received, the PDCCH is searched based on the third setting information. Then, when the setting information of the network device is received, the PDCCH is searched with priority based on the setting information transmitted from the network device.
As an option, the third setting information may be determined based on at least one of a frequency band, a carrier wave, a system bandwidth and a base parameter set.
For example, different frequency bands may correspond to different third setting information, different carrier waves may correspond to different third setting information, or different base parameter sets may correspond to different third setting information.
Hereinafter, the signal transmission method according to the embodiment of the present application will be described with reference to the specific example of FIG. 3-FIG. 6, and in the example of FIG. 3-FIG. 6, the first setting information or the second setting information will be described. Contains the time domain length of the time domain resource, the start position of the time domain resource and the time domain granularity corresponding to the time domain resource, the start position of the time domain resource is indicated by the time domain offset with respect to the synchronization signal or broadcast channel, and the time. The time domain granularity corresponding to the time domain resource is in units of symbols.
It should be understood that the method shown for the time domain resource in FIGS. 3-Fig. 6 is merely exemplary and not limiting, and the location information of the time domain resource is shown by the other method in the above-described embodiment. The start position of the time domain resource may be described by a time domain offset with respect to the time domain boundary or subframe boundary, and the time domain granularity may be described by other units in the above embodiment, for example, a plurality of time slots. Alternatively, a plurality of mini time slots or the like may be used.
As shown in FIG. 3, the first setting information is transmitted by the network device to the terminal device via RRC signaling, and the first setting information includes the following three pieces of information.
1. The time domain length of the first time domain resource, or also called the time domain length of the region containing the PDCCH, that is, in which region the PDCCH is searched.
2. It is the first time domain particle size corresponding to the first time domain resource, or is also called the time domain particle size of the PDCCH search space in the area containing the PDCCH, that is, the terminal device enters the PDCCH search space once. It is a search time interval or cycle, that is, how often the search space of PDCCH is searched in the area including PDCCH.
3. The start position of the first time domain resource, that is, the time domain offset of the start position of the region containing the PDCCH with respect to the sync signal or sync signal block or broadcast channel.
After receiving the first setting information, the terminal device starts the first time domain resource, that is, the time domain position of the time domain offset with respect to the synchronization signal or the synchronization signal block or the broadcast channel, based on the first setting information. , And the corresponding first time domain granularity, i.e. N symbols, so that the terminal device can perform PDCCH once every N symbols from the start position of the first time domain resource. The search, that is, the PDCCH is searched with N symbols as the cycle, and therefore, the signal transmission method of the embodiment of the present application is described when the network device is set to search the PDCCH by an arbitrary symbol. The network device sets the terminal device via the first setting information to search the PDCCH at a predetermined frequency (that is, the first time domain granularity) within a predetermined time domain range (that is, the first time domain resource). It can be set, thus reducing the complexity and power consumption of the terminal device searching for the PDCCH.
In the embodiment shown in FIGS. 4 and 5, the terminal device receives the first setting information, then further receives the second setting information in the first time domain resource, and the network device receives the second setting information. The content is transmitted via DCI, and the content included in the second setting information can refer to the content included in the first setting information in FIG. 3, and will not be repeatedly described here.
In the embodiment shown in FIGS. 4 and 5, the position information of the second time domain resource may be indicated by the time domain offset with respect to the synchronization signal, the synchronization signal block, or the broadcast channel, and is from DCI by default. It may be the start, that is, the time when the DCI is received is the start position of the second time domain resource.
After receiving the second setting information, the terminal device determines the second time domain resource and the second time domain granularity (M symbols) corresponding to the second time domain resource based on the second setting information. It can be determined, and the PDCCH is searched once every M symbols in the second time domain resource.
Since the second time domain resource is a subset of the first time domain resource, the terminal device is still outside the second time domain resource within the first time domain resource, every N symbols. That is, PDCCH can be searched by the first time domain particle size.
The second time domain grain size may be larger than the first time domain grain size. For example, in the embodiment shown in FIG. 4, the second time domain grain size is larger than the first time domain grain size, that is, the terminal device is the first. Searching for PDCCH in 2-time domain resources is less frequent. For example, if the network device determines within a predetermined period in the future that the terminal device does not need to search for PDCCH as frequently as the first time domain granularity, the second setting information may be used. The frequency with which the terminal device searches for PDCCH can be set again, and by setting the second time domain granularity of the second setting information to be larger than the first time domain granularity, the frequency with which the terminal device searches for PDCCH. To reduce.
Alternatively, the second time domain particle size may be smaller than the first time domain particle size. For example, in the embodiment shown in FIG. 5, the second time domain particle size is smaller than the first time domain particle size, that is, the terminal device. However, the frequency of searching for PDCCH in the second time domain resource increases. For example, the network device determines that the terminal device needs to search the PDCCH more frequently than the first time domain granularity (eg, it needs to transmit a low latency service) within a predetermined period in the future. If you, through the second setting information to the terminal device can be set again the frequency of searching PDCCH, less than the second time-domain granularity said first time domain particle size of the second setting information By setting, the frequency with which the terminal device searches for PDCCH is improved. That is, the network device can temporarily improve the search frequency of PDCCH via DCI to effectively support the low latency service.
In the embodiment shown in FIG. 6, when the terminal device has not received the setting information transmitted from the network device, the third time domain resource and the above are based on the default or predefined third setting information. The third time domain granularity (D symbols) corresponding to the third time domain resource is determined, and the content included in the third setting information can refer to the content included in the first setting information in FIG. 3, which can be referred to here. I will not explain it repeatedly.
The terminal device receives the second setting information transmitted from the network device in the process of searching PDCCH once every D symbols in the third time domain resource, and in this case, the terminal device receives the second setting information. Based on the second setting information, the second time domain resource and the second time domain granularity (M symbols) corresponding to the second time domain resource are determined, whereby in the second time domain resource. , Search PDCCH once every M symbols.
The end position of the third time domain resource may be later than the end position of the second time domain resource, may be earlier than the end position of the second time domain resource, and the end position of the third time domain resource may be earlier. If it is later than the end position of the second time domain resource, the terminal device may still search for PDCCH in the third time domain granularity in a region other than the second time domain resource of the third time domain resource. can. That is, outside the second time domain resource within the third time domain resource, the terminal device can still search for PDCCH once every D symbols.
As an option, the second time domain particle size may be larger than the third time domain particle size or smaller than the third time domain particle size, and FIG. 6 shows that the second time domain particle size is larger than the third time domain particle size.
