Detailed Description
The terminology used in the description of the embodiments section of the present application is for the purpose of describing particular embodiments of the present application only and is not intended to be limiting of the present application.
As shown in fig. 1, fig. 2 and fig. 3, an embodiment of the present application provides a method for receiving a semi-persistent scheduling physical downlink shared channel SPS PDSCH, including:
step 101, determining a first SPS PDSCH set according to high-level parameters, wherein the first SPS PDSCH set is a set of SPS PDSCHs to be received, which conflict with each other; the higher layer parameter may be indicated by, for example, radio Resource Control (RRC) configuration, medium Access Control (MAC) -Control Element (CE) configuration, or Downlink Control Information (DCI), and is not limited in particular.
Step 102, determining an SPS configuration index value, a transmission configuration indication state TCI state and a TCI state index value corresponding to each SPS PDSCH according to high-level parameters, wherein at least one SPS PDSCH in the first SPS PDSCH set corresponds to a plurality of TCI states;
for example, an example of a first set of SPS PDSCHs is illustrated in fig. 2, where the number following "#" indicates an SPS configuration Index value (Config Index), the number following the SPS PDSCH within parentheses indicates a TCI state, and the number following the TCI indicates an Index value of a TCI state, where an unfilled SPS PDSCH corresponds to one TCI state and a filled SPS PDSCH corresponds to two TCI states.
Step 103, determining a target TCI state in the TCI state corresponding to the SPS PDSCH in the first SPS PDSCH set, determining a target SPS PDSCH in the first SPS PDSCH set, and receiving the target SPS PDSCH based on the target TCI state.
Specifically, for example, in step 101, first, one SPS PDSCH is determined from SPS PDSCHs to be received in one time slot as shown in fig. 3, for example, one SPS PDSCH #0 with the smallest SPS configuration index value is used as the determined SPS PDSCH, and the set of the SPS PDSCH #0 and other SPS PDSCHs colliding with the SPS PDSCH #0 in the time slot is determined as the first set of SPS PDSCHs as shown in fig. 2. A target SPS PDSCH to be received is then determined based on steps 102 and 103 for the first set of SPS PDSCHs. For example, if SPS PDSCH #0 is determined to be the target SPS PDSCH and TCI1 is determined to be the target TCI state in step 103, SPS PDSCH #0 may be received based on TCI1, where TCI state is used to determine the beam direction in which to receive SPS PDSCH. For the first set of SPS PDSCHs, collision (overlapping time domains) occurs between SPS PDSCHs, and by the receiving method of the embodiment of the present application, a target SPS PDSCH may be selected for reception, so as to solve the problem of SPS PDSCH collision. After, for example, the first SPS PDSCH set composed of SPS PDSCH #0, SPS PDSCH #1, SPS PDSCH #3, SPS PDSCH #5, and SPS PDSCH #7 in fig. 3 determines the target TCI state and the target SPS PDSCH according to the above procedure, or after receiving the target SPS PDSCH based on the target TCI state, another SPS PDSCH may be determined among SPS PDSCHs other than SPS PDSCH #0, SPS PDSCH #1, SPS PDSCH #3, SPS PDSCH #5, and SPS PDSCH #7 in the time slot, that is, one SPS PDSCH #8 with the smallest SPS configuration index value among the remaining SPS PDSCHs of SPS PDSCH #8, SPS PDSCH #9, and SPS PDSCH #10 is used as the determined SPS PDSCH, SPS PDSCH #8 and the SPS PDSCH colliding with SPS PDSCH #8 are determined as a new first SPS PDSCH set, the target TCI state and the target SPS PDSCH are determined and received according to the same manner, and so on.
In the SPS PDSCH receiving method in the embodiment of the present application, the target TCI state and the target SPS PDSCH are determined in the SPS PDSCH to be received that conflicts with each other, and the target SPS PDSCH is received based on the target TCI state, so that the problem of how to receive the SPS PDSCH when the SPS PDSCH conflicts can be solved.
In one possible implementation, the target TCI state is one TCI state. If the terminal supports simultaneous reception of only one directional beam, the target SPS PDSCH may be received based on one TCI state.
In one possible embodiment, as shown in fig. 2, 4 and 5, the step 103 of determining a target TCI state in the TCI state corresponding to the SPS PDSCH in the first set of SPS PDSCH and determining a target SPS PDSCH in the first set of SPS PDSCH and receiving the target SPS PDSCH based on the target TCI state includes:
step 201, determining one of the SPS configuration index values which is minimum or maximum in the first SPS PDSCH set as a target SPS PDSCH;
step 202, judging whether the target SPS PDSCH corresponds to one TCI state or a plurality of TCI states, if the target SPS PDSCH corresponds to one TCI state, entering step 203, and if the target SPS PDSCH corresponds to a plurality of TCI states, entering step 204;
step 203, determining the TCI corresponding to the target SPS PDSCH as a target TCI state, and receiving the target SPS PDSCH based on the target TCI state;
step 204, determining one of the plurality of TCI states as a target TCI state, and receiving a target SPS PDSCH based on the target TCI state.
Specifically, for example, if the current first SPS PDSCH set is as shown in fig. 2, in step 201, it is assumed that one of the SPS configuration index values that is the smallest is determined as the target SPS PDSCH according to a preset rule, that is, SPS PDSCH #0 is determined as the target SPS PDSCH, then in step 202, it is determined that SPS PDSCH #0 corresponds to TCI1, that is, only one TCI state, so step 203 is entered, and SPS PDSCH #0 is received based on the TCI1 corresponding to SPS PDSCH #0. For another example, if the current first SPS PDSCH set is as shown in fig. 5, in step 201, it is assumed that one of the SPS configuration index values that is the smallest is determined as the target SPS PDSCH according to a preset rule, that is, SPS PDSCH #0 is determined as the target SPS PDSCH, then in step 202, it is determined that SPS PDSCH #0 corresponds to TCI2 and TCI3, that is, two TCI states, so step 204 is entered, and in TCI2 and TCI3, one is determined as the target TCI state according to the preset rule, for example, one of the TCI states that is the smallest index value is determined as the target TCI state according to the preset rule, for example, TCI2 is determined as the target TCI state, and SPS PDSCH #0 is received based on TCI2, it is understood that in other possible embodiments, the preset rule may also be another rule, for example, one of the TCI states that is the largest, the first TCI state, or the last TCI state is determined as the target TCI state.
In one possible embodiment, as shown in fig. 5, assuming that the terminal only supports simultaneous reception of beams in one direction, the step 103 of determining a target TCI state in the TCI state corresponding to the SPS PDSCH in the first set of SPS PDSCH, and determining the target SPS PDSCH in the first set of SPS PDSCH and receiving the target SPS PDSCH based on the target TCI state includes: and determining one of SPS configuration index values which is minimum or maximum in SPS PDSCHs corresponding to one TCI state in the first set of SPS PDSCHs as a target SPS PDSCH, determining a TCI state corresponding to the target SPS PDSCH as a target TCI state, and receiving the target SPS PDSCH based on the target TCI state.
Specifically, for example, if the current first SPS PDSCH set is as shown in fig. 5, SPS PDSCHs corresponding to one TCI state in the first SPS PDSCH set are SPS PDSCH #1, SPS PDSCH #3, and SPS PDSCH #5, assuming that one of the SPS configuration index values that is the smallest is determined as the target SPS PDSCH, that is, SPS PDSCH #1 is determined as the target SPS PDSCH, and TCI4 corresponding to SPS PDSCH #1 is determined as the target TCI state, SPS PDSCH #1 is received based on TCI 4. That is, in this embodiment, SPS PDSCHs corresponding to a plurality of TCI states are excluded, and one target SPS PDSCH and one corresponding target TCI state are determined among the remaining SPS PDSCHs for reception.
In one possible implementation, the target TCI state includes a first target TCI state and a second target TCI state. The target SPS PDSCH may be received based on two TCI states if the terminal supports simultaneous reception of beams in two directions.
In one possible embodiment, as shown in fig. 5 and fig. 6, the step 103 of determining a target TCI state in the TCI state corresponding to the SPS PDSCH in the first set of SPS PDSCH, and determining the target SPS PDSCH in the first set of SPS PDSCH and receiving the target SPS PDSCH based on the target TCI state includes:
step 301, determining one of SPS configuration index values of SPS PDSCHs corresponding to one TCI state in the first SPS PDSCH set as a first target SPS PDSCH, and determining the TCI state corresponding to the first target SPS PDSCH as a first target TCI state;
step 302, determining one of SPS PDSCH in the first set of SPS PDSCHs except for the first target SPS PDSCH and corresponding to one TCI state with the SPS configuration index value being the minimum or the maximum as a second target SPS PDSCH, and determining a TCI state corresponding to the second target SPS PDSCH as a second target TCI state;
step 303, receiving a first target SPS PDSCH based on the first target TCI state, and receiving a second target SPS PDSCH based on the second target TCI state.
Specifically, for example, if the current first SPS PDSCH set is as shown in fig. 5, SPS PDSCH #1 with the smallest SPS configuration index value among the non-padded SPS PDSCHs in fig. 5 is determined as the first target SPS PDSCH, its corresponding TCI4 is determined as the first target TCI state, SPS PDSCH #3 with the smallest SPS configuration index value among the remaining non-padded SPS PDSCHs is determined as the second target SPS PDSCH, its corresponding TCI1 is determined as the second target TCI state, SPS PDSCH #1 is received based on TCI4, and SPS PDSCH #3 is received based on TCI 1. That is, in this embodiment, SPS PDSCHs corresponding to a plurality of TCI states are excluded, and two target SPS PDSCHs and two corresponding target TCI states are determined among the remaining SPS PDSCHs for reception.
In one possible implementation, as shown in fig. 2 and 7, the step 103 of determining a target TCI state in the TCI states corresponding to the SPS PDSCHs in the first set of SPS PDSCHs, and determining a target SPS PDSCH in the first set of SPS PDSCHs, and receiving the target SPS PDSCH based on the target TCI state includes:
step 401, determining one of SPS configuration index values of SPS PDSCHs corresponding to multiple TCI states in the first SPS PDSCH set to be the minimum or maximum as a target SPS PDSCH;
