1. A method, comprising:
transmitting, by a first electronic device to a base station, uplink sounding reference signals (UL-SRSs) on N UL-SRS resources using N transmit beam patterns, wherein N is an integer greater than 1;
receiving, by the first electronic device from the base station, information associated with sidelink beam management (SL-BM), wherein the information associated with SL-BM indicates beam pattern indices indicating transmit beam patterns for SL-BM;
receiving, by the first electronic device from the base station, a relationship between the UL-SRSs and one or more sidelink beam management reference signals (SL-BMRSs),
wherein the relationship indicates Q transmit beam patterns from the N transmit beam patterns for SL-BM, Q being an integer greater than or equal to 1 and less than N, or
wherein the relationship indicates P transmit beam patterns from the N transmit beam patterns not for SL-BM, P being an integer greater than or equal to 1 and less than N; and
transmitting, by the first electronic device to a second electronic device, the one or more SL-BMRSs, based on the information associated with SL-BM, using beams from the Q transmit beam patterns or using transmit beam patterns that are included in the N transmit beam patterns and not included in the P transmit beam patterns.
