1. A buffer indication method, being applied to a user equipment (UE), and comprising:
when a to-be-sent first buffer state report (BSR) and a to-be-sent second BSR are present at the same time, in response to determining that an uplink media access control (MAC) protocol data unit (PDU) is incapable of carrying both a first BSR MAC control element (CE) and a second BSR MAC CE at the same time, adding an indication MAC CE to the uplink MAC PDU and sending the MAC PDU added with the indication MAC CE to a base station, wherein the indication MAC CE indicates that the UE has a to-be-sent BSR, the first BSR MAC CE carries the first BSR, and the second BSR MAC CE carries the second BSR,
wherein the to-be-sent BSR comprises the first BSR or the second BSR; when the first BSR is a sidelink BSR, the second BSR is an uplink BSR; or when the first BSR is an uplink BSR, the second BSR is a sidelink BSR;
receiving information on an uplink resource sent by the base station to the UE based on the indication MAC CE;
sending a to-be-sent BSR MAC CE to the base station based on the uplink resource, wherein the to-be-sent BSR MAC CE carries the to-be-sent BSR; and
receiving information on a transmission resource of a corresponding type sent by the base station to the UE based on the to-be-sent BSR.
