Wherein the data channel is a physical downlink shared channel (physical downlink shared channel, PDSCH).
In some embodiments, the control resource set of the data channel is a control resource set associated with the PDCCH in which the downlink control information of the data channel is triggered or activated or scheduled.
S202, if a plurality of data channels overlap in time domain, the terminal equipment determines two target data channels from the plurality of data channels according to SPS configuration indexes associated with the plurality of data channels.
The plurality of data channels may overlap in the time domain, or may overlap in whole or in part.
In some embodiments, in a multi-transmission reception point (multi-TRP) transmission scenario based on multiple DCI triggers/schedules, and where a terminal device is configured with multiple SPS configurations, two target data channels may be determined from multiple data channels due to the terminal device's ability to receive and/or decode the multiple data channels, thereby improving the efficiency of the communication system.
The embodiment of the application does not limit how to determine two target data channels from a plurality of data channels, and can be specifically set according to actual situations.
In some embodiments, the terminal device may use the data channels corresponding to the two SPS configuration indexes with the smallest values as the target data channels; or, the terminal device may use two data channels corresponding to one SPS configuration index with the smallest value as the target data channels.
In some embodiments, the configuration information further includes a first higher layer signaling, and the terminal device may determine, according to a value of the first higher layer signaling, a first type of data channel and a second type of data channel from the plurality of data channels, and then determine, from the first type of data channel and the second type of data channel, a data channel associated with an SPS configuration index having a minimum value, as the target data channel, respectively.
S203, the terminal equipment receives and/or decodes the target data channel.
In the implementation of the present application, after the terminal device determines two target data channels from the multiple data channels, the target data channels may be received and/or decoded.
The embodiments of the present application do not limit how to receive and/or decode the target data channel, and may be performed according to the existing manner of receiving and/or decoding the data channel.
According to the communication method provided by the embodiment of the application, the terminal equipment receives configuration information of a plurality of data channels transmitted by a Physical Downlink Control Channel (PDCCH), wherein the configuration information comprises a semi-persistent scheduling (SPS) configuration index, and then if the plurality of data channels are overlapped in a time domain, the terminal equipment determines two target data channels from the plurality of data channels according to the SPS configuration index associated with the plurality of data channels. Finally, the terminal device receives and/or decodes the target data channel. In this way, when there is no overlapping of multiple data channels transmitted by the corresponding PDCCH in the time domain, the terminal device can determine that two target data channels are received and/or decoded, and not only one target data channel is received and/or decoded, thereby improving the efficiency of the communication system.
Based on the above embodiments, a description will be given below of how two target data channels are determined from a plurality of data channels directly from an SPS configuration index. Fig. 3 is a signaling interaction diagram of another communication method provided in an embodiment of the present application, as shown in fig. 3, where the method includes:
s301, a network device or a forwarding device sends configuration information of a plurality of data channels transmitted by a PDCCH (physical downlink control channel) without corresponding, wherein the configuration information comprises a SPS (semi-persistent scheduling) configuration index.
The technical terms, effects, features, and alternative embodiments of S301 may be understood with reference to S201 shown in fig. 2, and will not be described here again for repeated contents.
S302, if a plurality of data channels are overlapped in the time domain, the terminal equipment takes the data channel corresponding to the two SPS configuration indexes with the minimum value as a target data channel; or the terminal equipment takes two data channels corresponding to one SPS configuration index with the minimum value as target data channels.
In this embodiment, if multiple data channels overlap in the time domain, the terminal device does not need to decode the data channels except the data channels corresponding to the two minimum SPS configuration indexes.
In some embodiments, if one SPS configuration index corresponds to one data channel, the terminal device uses the data channel corresponding to the two SPS configuration indexes with the smallest value as the target data channel.
For example, the terminal device receives sps-ConfigIndex corresponding to four data channels PDSCH 0, PDSCH 1, PDSCH2 and PDSCH 3. Wherein, the sps-ConfigIndex takes a value of 0, and the associated PDSCH is PDSCH 0; the sps-ConfigIndex takes a value of 1, and the associated PDSCH is PDSCH 1; the sps-ConfigIndex takes a value of 2, and the associated PDSCH is PDSCH 2; the sps-ConfigIndex takes a value of 3 and its associated PDSCH is PDSCH 3. If PDSCH 0, PDSCH 1, PDSCH2, PDSCH3 overlap in the time domain, the terminal device does not expect decoding and/or PDSCH other than PDSCH 0, PDSCH 1.
In other embodiments, if one SPS configuration index corresponds to two data channels, the terminal device uses the two data channels corresponding to the SPS configuration index with the smallest value as the target data channel.
For example, the terminal device receives sps-ConfigIndex corresponding to four data channels PDSCH 0, PDSCH1, PDSCH2 and PDSCH 3. Wherein, sps-ConfigIndex takes a value of 0, and the associated PDSCH is PDSCH 0 and PDSCH 1; the sps-ConfigIndex takes a value of 1, and the associated PDSCH is PDSCH2 and PDSCH 3. If PDSCH 0, PDSCH1, PDSCH2, PDSCH 3 overlap in the time domain, the terminal device does not expect decoding and/or PDSCH other than PDSCH 0, PDSCH 1.
S303, the terminal equipment receives and/or decodes the target data channel.
The technical terms, effects, features, and alternative embodiments of S303 may be understood with reference to S203 shown in fig. 2, and will not be described here again for repeated contents.
According to the communication method provided by the embodiment of the application, the terminal equipment receives configuration information of a plurality of data channels transmitted by a Physical Downlink Control Channel (PDCCH), wherein the configuration information comprises a semi-persistent scheduling (SPS) configuration index. Then, if a plurality of data channels overlap in time domain, the terminal equipment takes the data channel corresponding to the two SPS configuration indexes with the minimum value as a target data channel; or the terminal equipment takes two data channels corresponding to one SPS configuration index with the minimum value as target data channels. Finally, the terminal device receives and/or decodes the target data channel. In this way, when there is no overlapping of multiple data channels transmitted by the corresponding PDCCH in the time domain, the terminal device can determine that two target data channels are received and/or decoded, and not only one target data channel is received and/or decoded, thereby improving the efficiency of the communication system.
On the basis of the above embodiment, the configuration information received by the terminal device includes, in addition to the SPS configuration index, the first higher layer signaling, and accordingly, the terminal device may determine two target data channels from the plurality of data channels by combining the SPS configuration index and the first higher layer signaling. Fig. 4 is a signaling interaction diagram of another communication method according to an embodiment of the present application, as shown in fig. 4, where the method includes:
s401, the network device or the forwarding device sends configuration information of a plurality of data channels transmitted by a PDCCH (physical downlink control channel) without corresponding, wherein the configuration information comprises a SPS (semi-persistent scheduling) configuration index and a first high-layer signaling.
Wherein the first higher layer signaling is used to distinguish from which TRP the PDCCH or the plurality of data channels come. The first higher layer signaling is included in a control resource set (control resource set, CORESET) of the data channel, or the first higher layer signaling may be included in an SPS configuration of the data channel.
In some embodiments, if the first higher layer signaling is included in the control resource set of the data channel, the control resource set of the data channel is the control resource set associated with the PDCCH that triggers or activates or schedules the downlink control information of the data channel.
S402, the terminal equipment determines a first type data channel and a second type data channel from a plurality of data channels according to the value of the first high-layer signaling.
S403, the terminal equipment respectively determines a data channel associated with the SPS configuration index with the minimum value from the first type of data channel and the second type of data channel as a target data channel.
In step S402 and step S403, after receiving the configuration information, the terminal device may distinguish the first type data channel and the second type data channel from the plurality of data channels according to the value of the first higher layer signaling, and then determine, from the first type data channel and the second type data channel, a data channel associated with the SPS configuration index having the smallest value, as the target data channel.
In some embodiments, the first higher layer signaling is contained in a control resource set of the data channel. The value of the first higher layer signaling coresetpoolndex in the control resource set associated with the PDCCH triggering or activating or scheduling the data channel is 0, it may be determined that the associated data channel is a first type of data channel. The value of the first higher layer signaling coresetpoolndex in the control resource set associated with the PDCCH triggering or activating or scheduling the data channel is 1, it may be determined that the associated data channel is a second type of data channel. For the first type of data channel, the terminal device need not decode data channels other than the data channel of the minimum SPS configuration index in the first type of data channel. For the second type of data channel, the terminal device need not decode data channels other than the data channel of the minimum SPS configuration index in the second type of data channel.
For example, the terminal device receives the sps-ConfigIndex corresponding to the four data channels PDSCH 0, PDSCH 1, PDSCH2 and PDSCH 4 and the coresetpoolndex included in CORESET associated with the PDCCH in which the DCI activating the PDSCH is located. Wherein, sps-ConfigIndex takes the value of 0, the associated PDSCH is PDSCH 0, and CORESETPoolIndex contained in CORESEET associated with PDCCH where DCI of PDSCH 0 is activated takes the value of 0; the sps-ConfigIndex takes a value of 1, the associated PDSCH is PDSCH 1, and the CORESEETPoolIndex contained in CORESET associated with PDCCH where DCI of PDSCH 1 is activated takes a value of 0; the sps-ConfigIndex takes a value of 2, the associated PDSCH is PDSCH2, and the CORESETPoolIndex contained in CORESEET associated with the PDCCH where DCI of the PDSCH2 is activated takes a value of 1; the sps-ConfigIndex is given a value of 3, the PDSCH associated therewith is PDSCH 3, and the coresetpoolndex included in CORESET associated with the PDCCH in which the DCI of PDSCH 3 is activated is given a value of 1.
Accordingly, the terminal device may determine that the first type of PDSCH includes PDSCH 0, PDSCH 1, and the second type of PDSCH includes PDSCH2, PDSCH 3. If PDSCH 0, PDSCH 1, PDSCH2, PDSCH 3 overlap in the time domain, the terminal device determines the target PDSCH as PDSCH 0 in the first type of PDSCH and the target PDSCH as PDSCH2 in the second type of PDSCH.
In some embodiments, the first higher layer signaling is included in an SPS configuration of the data channel. It should be noted that, in the embodiment of the present application, how the first higher layer signaling is named is not limited, and by way of example, the first higher layer signaling may be coresetpoolndex. If the value of the first higher layer signaling contained in the SPS configuration is 0, the terminal equipment can determine the associated data channel as the data channel of the first type; if the SPS configuration includes a value of 1 for the first higher layer signaling, the terminal device may determine that the associated data channel is a second type of data channel. For the first type of data channel, the terminal device need not decode data channels other than the data channel of the minimum SPS configuration index in the first type of data channel. For the second type of data channel, the terminal device need not decode data channels other than the data channel of the minimum SPS configuration index in the second type of data channel.
For example, the terminal device receives SPS-ConfigIndex and CORESEETPoolIndex in SPS configuration corresponding to four data channels PDSCH 0, PDSCH 1, PDSCH2 and PDSCH 3. The sps-ConfigIndex takes the value of 0, the associated PDSCH is PDSCH 0, and the higher layer signaling contained in the associated sps-Config takes the value of 0; the sps-ConfigIndex takes a value of 1, the associated PDSCH is PDSCH 1, and the higher layer signaling contained in the associated sps-Config takes a value of 0; the sps-ConfigIndex takes a value of 2, the associated PDSCH is PDSCH2, and the higher-layer signaling contained in the associated sps-Config takes a value of 1; the sps-ConfigIndex is given a value of 3, the PDSCH associated therewith is PDSCH 3, and the higher layer signaling included in the sps-Config associated therewith is given a value of 1.
Accordingly, the terminal device may determine that the first type of PDSCH includes PDSCH 0, PDSCH 1, and the second type of PDSCH includes PDSCH 2, PDSCH 3. If PDSCH 0, PDSCH 1, PDSCH 2, PDSCH 3 overlap in the time domain, the terminal device determines the target PDSCH as PDSCH 0 in the first type of PDSCH and the target PDSCH as PDSCH 2 in the second type of PDSCH.

The terminal equipment respectively determines a data channel associated with the SPS configuration index with the minimum value from the first type of data channel and the second type of data channel as a target data channel. The target data channel is received and/or decoded. In this way, when there is no overlapping of multiple data channels transmitted by the corresponding PDCCH in the time domain, the terminal device can determine that two target data channels are received and/or decoded, and not only one target data channel is received and/or decoded, thereby improving the efficiency of the communication system.
