1. A communication method, wherein the method is applied to a terminal device, and the method comprises:
sending feedback information of a first data packet of a first multicast service, wherein downlink control information (DCI) for scheduling the first data packet is scrambled by group radio network temporary identifier (G-RNTI);
receiving a second information, wherein the second information comprises a discontinuous reception (DRX) configuration information corresponding to a first unicast service, the DRX configuration information corresponding to the first unicast service comprises duration of a second downlink hybrid automatic repeat request round trip time timer (HARQ RTT) timer and duration of a second downlink DRX retransmission timer, and a data packet of the first unicast service is scrambled by cell radio network temporary identifier (C-RNTI);
starting the second downlink HARQ RTT timer at a first moment after an end of sending the feedback information; and
monitoring, based on DRX configuration information, a Physical Downlink Control Channel (PDCCH) for scheduling information of a data packet of the first multicast service, wherein the scheduling information is scrambled by the C-RNTI.
