1. A Timing Advance (TA) configuration method, comprising:
transmitting, by a terminal, a first Sounding Reference Signal (SRS) to a network side device on N SRS resource sets through N antenna groups respectively, N being an integer greater than 1; and
receiving, by the terminal, a first configuration message transmitted by the network side device, the first configuration message being used to configure N TAs, the N TAs corresponding to the N antenna groups respectively, the N TAs being obtained by the network side device through measuring the first SRS on the N SRS resource sets.
