Abstract
Example implementations include a method, apparatus and computer-readable medium of wireless communication. A user equipment (UE) may determine, based on a sidelink resource configuration from a base station, a physical sidelink control/shared channel (PSCCH/PSSCH) occasion to monitor for a sidelink transmission from a second UE. The UE may receive, during the PSCCH/PSSCH occasion, a signal indicative of a sidelink discontinuous reception (DRX) command. The UE may determine to stop monitoring the PSCCH for the PSCCH/PSSCH occasion in response to the sidelink DRX command.
Claims29
A method of wireless communications, comprising, at a first user equipment (UE):
- identifying, based on a sidelink resource configuration from a base station, a physical sidelink control/shared channel (PSCCH/PSSCH) occasion to monitor for a sidelink transmission from a second UE;
- receiving, during the PSCCH/PSSCH occasion, a sidelink discontinuous reception (DRX) command;
- and
- stopping monitoring of the PSCCH for the PSCCH/PSSCH occasion in response to the sidelink DRX command, wherein stopping monitoring of the PSCCH comprises monitoring a physical downlink control channel (PDCCH) and not monitoring the PSCCH in response to being in a DRX active state for a link with the base station.
A method of wireless communications, comprising, at a first user equipment (UE):
- identifying, based on a sidelink resource configuration from a base station, a physical sidelink control/shared channel (PSCCH/PSSCH) occasion to monitor for a sidelink transmission from a second UE;
- receiving, during the PSCCH/PSSCH occasion, a sidelink discontinuous reception (DRX) command;
- stopping monitoring of the PSCCH for the PSCCH/PSSCH occasion in response to the sidelink DRX command;
- and
- informing the base station that a portion of the PSCCH/PSSCH occasion is unused in response to not being in a DRX active state for a link with the base station.
A method of wireless communications, comprising, at a first user equipment (UE):
- identifying, based on a sidelink resource configuration from a base station, a physical sidelink control/shared channel (PSCCH/PSSCH) occasion to monitor for a sidelink transmission from a second UE;
- receiving, during the PSCCH/PSSCH occasion, a sidelink discontinuous reception (DRX) command;
- stopping monitoring of the PSCCH for the PSCCH/PSSCH occasion in response to the sidelink DRX command;
- informing the second UE of a duration of a DRX active state for a link with the base station in response to being in the DRX active state for the link with the base station;
- and
- monitoring the PSCCH for the duration of the DRX active state.
An apparatus for wireless communication for a first user equipment (UE), comprising:
- a memory storing computer-executable instructions;
- and
- at least one processor coupled to the memory and configured to execute the computer-executable instructions to:
- identify, based on a sidelink resource configuration from a base station, a physical sidelink control/shared channel (PSCCH/PSSCH) occasion to monitor for a sidelink transmission from a second UE;
- receive, during the PSCCH/PSSCH occasion, a sidelink discontinuous reception (DRX) command;
- and
- stop monitoring of the PSCCH for the PSCCH/PSSCH occasion in response to the sidelink DRX command, wherein the at least one processor is configured to monitor a physical downlink control channel (PDCCH) and not monitor the PSCCH in response to being in a DRX active state for a link with the base station.
An apparatus for wireless communications at a first user equipment, comprising:
- means for determining, based on a sidelink resource configuration from a base station, a physical sidelink control/shared channel (PSCCH/PSSCH) occasion to monitor for a sidelink transmission from a second UE;
- means for receiving, during the PSCCH/PSSCH occasion, a sidelink discontinuous reception (DRX) command;
- and
- means for stopping monitoring of the PSCCH for the PSCCH/PSSCH occasion in response to the sidelink DRX command, wherein the means for stopping monitoring of the PSCCH is configured to monitor a physical downlink control channel (PDCCH) and not monitoring the PSCCH in response to being in a DRX active state for a link with the base station.
A non-transitory computer-readable medium storing computer executable code, the code when executed by a processor of a first user equipment (UE) causes the processor to:
- determine, based on a sidelink resource configuration from a base station, a physical sidelink control/shared channel (PSCCH/PSSCH) occasion to monitor for a sidelink transmission from a second UE;
- receive, during the PSCCH/PSSCH occasion, a sidelink discontinuous reception (DRX) command;
- and
- stop monitoring of the PSCCH for the PSCCH/PSSCH occasion in response to the sidelink DRX command, wherein the code to stop monitoring of the PSCCH includes instructions to monitor a physical downlink control channel (PDCCH) and not monitor the PSCCH in response to being in a DRX active state for a link with the base station.
