Abstract
Systems and methods for communicating sounding reference signals (SRS) in a cellular time division duplex (TDD) mmWave system. A transmission point TP may transmit beamformed reference signals to the user equipment UE and each of the beamformed reference signals is transmitted along a beam direction in a set of beam directions available by the TP . The TP may receive, from the UE, a feedback message identifying one of the beamformed reference signals transmitted to the UE. The TP selects, from a set of beam directions available by the TP, a subset of beam directions for SRS reception based on a feedback message received from the UE, And thus can receive uplink SRS signals. The set of beam directions available by the TP includes at least one beam direction that is excluded from the subset of beam directions.
