Sounding reference signal (SRS) design for cellular time division duplex (TDD) mmWave systems

A method comprising:

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

A user equipment (UE) comprising:

• at least one processor;
• and
• a non-transitory computer readable storage medium storing programming, the programming including instructions that, when executed by the at least one processor, cause the UE to perform operations including:
• receiving a sounding reference signal (SRS) configuration parameter;
• receiving, from a base station, at least one downlink synchronization signal;
• and
• transmitting, based on the SRS configuration parameter, an uplink SRS using a beam parameter, the beam parameter being based on the at least one downlink synchronization signal.
