Abstract
A DRX-based communication method for power saving in sidelink communication is disclosed. A method for operation of a base station includes the steps of: transmitting information of PSFCH intervals to a terminal; determining an SL DRX cycle on the basis of the PSFCH intervals; and transmitting information of the SL DRX cycle to the terminal, wherein the SL DRX cycle is determined such that a PSFCH according to the PSFCH intervals is located within an on-duration of the SL DRX cycle.

A method of a base station, the method comprising:
- transmitting, to a user equipment (UE), information of a physical sidelink feedback channel (PSFCH) periodicity;
- determining a sidelink (SL) discontinuous reception (DRX) cycle based on the PSFCH periodicity;
- and
- transmitting information on the SL DRX cycle to the UE,
- wherein the SL DRX cycle is determined so that a PSFCH according to the PSFCH periodicity is located within an on-duration of the SL DRX cycle, and
- based on multiplexing of hybrid automatic repeat request (HARQ) responses being allowed on one PSFCH, the SL DRX cycle is set as a product of the PSFCH periodicity and a maximum number of HARQ responses multiplexed on the one PSFCH.
A method of a user equipment (UE), the method comprising:
- receiving, from a base station, information of a physical sidelink feedback channel (PSFCH) periodicity;
- receiving, from the base station, information on a sidelink (SL) discontinuous reception (DRX) cycle determined based on the PSFCH periodicity;
- and
- performing a SL DRX operation based on the SL DRX cycle,
- wherein the SL DRX cycle is determined so that a PSFCH according to the PSFCH periodicity is located within an on-duration of the SL DRX cycle, and
- based on multiplexing of hybrid automatic repeat request (HARQ) responses being allowed on one PSFCH, the SL DRX cycle is set as a product of the PSFCH periodicity and a maximum number of HARQ responses multiplexed on the one PSFCH.
A method of a user equipment (UE), the method comprising:
- receiving physical sidelink feedback channel (PSFCH) configuration information from a base station;
- determining a sidelink (SL) discontinuous reception (DRX) cycle based on a PSFCH periodicity indicated by the PSFCH configuration information;
- and
- performing a SL DRX operation based on the SL DRX cycle,
- wherein the SL DRX cycle is determined so that a PSFCH according to the PSFCH periodicity is located within an on-duration of the SL DRX cycle, and
- based on multiplexing of hybrid automatic repeat request (HARQ) responses being allowed on one PSFCH, the SL DRX cycle is set as a product of the PSFCH periodicity and a maximum number of HARQ responses multiplexed on the one PSFCH.
