Communication method and apparatus

Abstract

A communication method and apparatus to enable uplink transmission of a terminal to be synchronized with a plurality of stations corresponding to one cell, and avoid a performance loss of uplink transmission. The terminal receives configuration information from a network device, wherein the configuration information includes two timing advance groups (TAGs) corresponding to one cell, and each TAG corresponds to one timing advance (TA). The terminal receives a plurality of random access response messages from the network device, wherein each random access response message is usable to indicate a TA corresponding to one of the two TAGs.
