Abstract
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. According to the present disclosure, when a configured grant is set, a terminal and a base station can efficiently transmit and receive data even when data to be transmitted from a CG resource has a short transmission time requirement.
Claims15
A method performed by a terminal in a wireless communication system, the method comprising:
- receiving a control message comprising configured grant (CG) configuration information from a base station;
- based on the CG configuration information, identifying that information indicating deactivation of retransmission monitoring is configured;
- receiving information on an uplink transmission through a physical downlink control channel (PDCCH), the information on the uplink transmission being associated with a configured scheduling-radio network temporary identifier (CS-RNTI) having a new data indicator (NDI) configured as 0;
- and
- driving a discontinuous reception (DRX)-hybrid automatic repeat request (HARQ)-round trip time (RTT) timer after a first uplink data transmission based on the information received through the PDCCH.
