Abstract
A system and method of communicating sounding reference signals (SRSs) in a cellular time division duplex (TDD) mmWave system. A transmission point (TP) may transmit beamformed reference signals to a user equipment (UE), each of the beamformed reference signals having been transmitted according to a beam direction in a set of beam directions available to the TP. The TP may receive a feedback message from the UE that identifies one of the beamformed reference signals transmitted to the UE. The TP may select, from the set of beam directions available to the TP, a subset of beam directions for SRS reception based on the feedback message received from the UE, and receive uplink SRS signals according to beam directions in the subset of beam directions. The set of beam directions available to the TP includes at least one beam direction that is excluded from the subset of beam directions.
