Abstract
The disclosure relates to a 5th generation (5G) or 6th generation (6G) communication system for supporting a higher data transmission rate. A method performed by user equipment (UE) in a wireless communication system is provided. The method includes receiving, from a base station (BS), a unicast related downlink signal, in case that a unicast discontinuous reception (DRX) and a multicast DRX are configured, stopping a unicast DRX retransmission timer based on the received unicast related downlink signal, and stopping a multicast DRX retransmission timer based on the received unicast related downlink signal.
Claims12
A method performed by user equipment (UE) in a wireless communication system, the method comprising:
- receiving, from a base station (BS), a unicast related downlink signal scheduled by a semi-persistent scheduling (SPS), in case that a unicast discontinuous reception (DRX) and a multicast DRX are configured;
- stopping a unicast DRX retransmission timer based on the unicast related downlink signal;
- and
- stopping a multicast DRX retransmission timer based on the unicast related downlink signal,
- wherein the unicast DRX retransmission timer and the multicast DRX retransmission timer are stopped if the unicast related downlink signal is identified by monitoring a physical downlink control channel (PDCCH) scrambled with a cell radio network temporary identifier (C-RNTI).
A user equipment (UE) in a wireless communication system, the UE comprising:
- at least one transceiver;
- at least one processor communicatively coupled to the at least one transceiver;
- and
- at least one memory, communicatively coupled to the at least one processor, storing instructions executable by the at least one processor individually or in any combination to cause the UE to:
- receive, from a base station (BS), a unicast related downlink signal scheduled by a semi-persistent scheduling (SPS), in case that a unicast discontinuous reception (DRX) and a multicast DRX are configured,
- stop a unicast DRX retransmission timer based on the unicast related downlink signal, and
- stop a multicast DRX retransmission timer based on the unicast related downlink signal,
- wherein the unicast DRX retransmission timer and the multicast DRX retransmission timer are stopped if the unicast related downlink signal is identified by monitoring a physical downlink control channel (PDCCH) scrambled with a cell radio network temporary identifier (C-RNTI).
A method performed by base station (BS) in a wireless communication system, the method comprising:
- transmitting, to user equipment (UE), a unicast related downlink signal scheduled by a semi-persistent scheduling (SPS), in case that a unicast discontinuous reception (DRX) and a multicast DRX are configured for the UE,
- wherein a unicast DRX retransmission timer is stopped based on the unicast related downlink signal,
- wherein a multicast DRX retransmission timer is stopped based on the unicast related downlink signal,
- wherein the unicast DRX retransmission timer and the multicast DRX retransmission timer are stopped if the unicast related downlink signal is identified by monitoring a physical downlink control channel (PDCCH) scrambled with a cell radio network temporary identifier (C-RNTI).
A base station (BS) in a wireless communication system, the BS comprising:
- at least one transceiver;
- at least one processor communicatively coupled to the at least one transceiver;
- and
- at least one memory, communicatively coupled to the at least one processor, storing instructions executable by the at least one processor individually or in any combination to cause the BS to:
- transmit, to user equipment (UE), a unicast related downlink signal scheduled by a semi-persistent scheduling (SPS), in case that a unicast discontinuous reception (DRX) and a multicast DRX are configured for the UE,
- wherein a unicast DRX retransmission timer is stopped based on the unicast related downlink signal,
- wherein a multicast DRX retransmission timer is stopped based on the unicast related downlink signal,
- wherein the unicast DRX retransmission timer and the multicast DRX retransmission timer are stopped if the unicast related downlink signal is identified by monitoring a physical downlink control channel (PDCCH) scrambled with a cell radio network temporary identifier (C-RNTI).
