Systems, methods, apparatuses, and computer program products for controlling sounding reference signal (SRS) transmission are provided. One method includes incorporating into an uplink grant message, by a base station in a communications system, information on whether a last symbol of an uplink subframe is used for physical uplink shared channel (PUSCH), for sounding reference signal (SRS), or is empty. The method may then include transmitting the uplink grant message comprising the information on the last symbol to a user equipment (UE). |
