Abstract
The disclosure provides a method for sidelink channel state information (CSI) reporting in a wireless communication system. The method comprises steps in which: a user equipment (UE) obtains parameters associated with discontinuous reception (DRX); the UE transmits, to a peer UE, a CSI request; and the UE monitors a sidelink channel in an active time of the DRX for receiving, from the peer UE, sidelink CSI in response to the CSI request, wherein the active time of the DRX includes a time duration between transmitting the CSI request and receiving the sidelink CSI.
Claims8
A method performed by a first user equipment (UE) in a wireless communication system, the method comprising:
- obtaining parameters associated with a sidelink discontinuous reception (DRX) for the first UE;
- transmitting, to a second UE, 2nd stage sidelink control information (SCI) on a physical sidelink shared channel (PSSCH), the 2nd stage SCI including a channel state information (CSI) request;
- and
- monitoring a sidelink channel in an active time of the sidelink DRX,
- wherein the active time of the sidelink DRX includes a period of a sidelink CSI report-related timer associated with the CSI request, in case that a sidelink CSI report is not received from the second UE, and
- wherein the period of the sidelink CSI report-related timer is indicated by a number of slots.
A first user equipment (UE) in a wireless communication system, the first UE comprising:
- a transceiver;
- and
- a controller functionally connected to the transceiver,
- wherein the controller is configured to:
- obtain parameters associated with a sidelink discontinuous reception (DRX) for the first UE;
- transmit, to a second UE, via the transceiver, 2nd stage sidelink control information (SCI) on a physical sidelink shared channel (PSSCH), the 2nd stage SCI including a channel state information (CSI) request;
- and
- monitor a sidelink channel in an active time of the sidelink DRX,
- wherein the active time of the sidelink DRX includes a period of a sidelink CSI report-related timer associated with the CSI request, in case that a sidelink CSI report is not received from the second UE, and
- wherein the period of the sidelink CSI report-related timer is indicated by a number of slots.
