UPLINK REFERENCE SIGNAL-BASED FREQUENCY OFFSET PRE-COMPENSATION

Abstract:

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine, based at least in part on a first downlink reference signal transmitted from a first base station using a downlink reference signal frequency, a first frequency offset associated with transmissions between the UE and the first base station. The UE may determine, based at least in part on a second downlink reference signal transmitted from a second base station using the downlink reference signal frequency, a second frequency offset associated with transmissions between the UE and the second base station. The UE may transmit, to the first base station and the second base station, at least one uplink reference signal using an uplink reference signal frequency that is based at least in part on the first frequency offset and the second frequency offset.
