Method performed by user equipment, and user equipment
The present disclosure provides a method performed by user equipment and user equipment. The method includes: receiving sidelink configuration information; receiving sidelink control information (SCI) transmitted by other user equipment and a corresponding physical sidelink shared channel (PSSCH); determining a transmission slot S of a physical sidelink feedback channel (PSFCH) corresponding to the PSSCH; and determining N sidelink slots associated with the slot S, where N is a positive integer.
1. A method performed by a user equipment, comprising:
receiving a sidelink Radio Resource Control (RRC) configuration transmitted from a New Radio base station (gNB), wherein the sidelink RRC configuration includes a resource pool configuration, wherein the resource pool configuration includes a configuration of a Physical Sidelink Feedback Channel (PSFCH) periodicity N;
receiving Sidelink Control Information (SCI) and a Physical Sidelink Shared Channel (PSSCH) scheduled by the SCI in a slot; and
determining Physical Resource Blocks (PRBs) for a PSFCH that is for a feedback sidelink Hybrid Automatic Repeat Request (HARQ) and that corresponds to the PSSCH based on at least i, wherein the slot for the PSSCH is an (i+1)th slot among slots associated with a PSFCH slot for the PSFCH, where i=0, 1, . . . , N−1.
2. A user equipment, comprising:
a processor;
memory;
reception circuitry configured to:
receive a sidelink Radio Resource Control (RRC) configuration transmitted from a New Radio base station (gNB), wherein the sidelink RRC configuration includes a resource pool configuration, wherein the resource pool configuration includes a configuration of a Physical Sidelink Feedback Channel (PSFCH) periodicity N, and
receive Sidelink Control Information (SCI) and a Physical Sidelink Shared Channel (PSSCH) scheduled by the SCI in a slot; and
determination circuitry configured to determine Physical Resource Blocks (PRBs) for a PSFCH that is for a feedback sidelink Hybrid Automatic Repeat Request (HARQ) and that corresponds to the PSSCH based on at least i, wherein the slot for the PSSCH is an (i+1)th slot among slots associated with a PSFCH slot for the PSFCH, where i=0, 1, . . . , N−1.
3. A base station apparatus comprising:
a processor;
memory; and
transmission circuitry configured to:
transmit a sidelink Radio Resource Control (RRC) configuration to a user equipment, wherein the sidelink RRC configuration includes a resource pool configuration, wherein the resource pool configuration includes a configuration of a Physical Sidelink Feedback Channel (PSFCH) periodicity N,
the sidelink RRC configuration being transmitted so as to cause the user equipment to:
receive Sidelink Control Information (SCI) and a Physical Sidelink Shared Channel (PSSCH) scheduled by the SCI in a slot, and
determine Physical Resource Blocks (PRBs) for a PSFCH that is for a feedback sidelink Hybrid Automatic Repeat Request (HARQ) and that corresponds to the PSSCH based on at least i, wherein the slot for the PSSCH is an (i+1)th slot among slots associated with a PSFCH slot for the PSFCH, where i=0, 1, . . . , N−1.
