1. A method comprising:
receiving, by a user equipment (UE), a sounding reference signal (SRS) configuration parameter;
receiving, by the UE from a base station, at least one downlink synchronization signal; and
transmitting based on the SRS configuration parameter, by the UE, an uplink SRS using a beam parameter, the beam parameter being based on the at least one downlink synchronization signal.
