1. A communication method performed by a network side device, comprising:
broadcasting an uplink data sending announcement, wherein the uplink data sending announcement is used to determine a sending time for feeding back buffer information that enables one or more terminals to simultaneously feed back the buffer information, wherein the buffer information comprises a backoff timer value;
receiving the buffer information from the one or more terminals that need to send data, wherein the buffer information comprises a sending level indicating an access priority of data to be sent;
selecting, from the one or more terminals that need to send data, a terminal that is allowed to send data, and
sending, to the terminal, a frame that carries scheduling information, wherein the scheduling information is determined according to the buffer information and instructs the terminal to send the data.
