1. A pending scheduling request SR cancellation method, applied in a communications apparatus, comprising:
triggering SRs; and
when an uplink grant meets a first condition or an uplink medium access control (MAC) protocol data unit (PDU) meets a second condition, canceling all pending first-type SRs in the SRs, wherein the first-type SR is an SR triggered by an uplink buffer status report (BSR); and
when a sidelink grant meets a third condition, or the uplink MAC PDU meets a fourth condition, canceling all pending second-type SRs in the SRs, wherein the second-type SR is an SR triggered by a first sidelink BSR;
wherein that the uplink MAC PDU meets the second condition comprises: the uplink MAC PDU comprises a non-truncated uplink BSR MAC control element (CE), wherein the non-truncated uplink BSR MAC CE comprises a buffer status of the communications apparatus up to and comprising a last event that triggers the uplink BSR before the uplink MAC PDU is assembled; and
the canceling all pending first-type SRs comprises: when the uplink MAC PDU is transmitted, canceling all pending first-type SRs that are triggered before the uplink MAC PDU is assembled.
