CROSS-SLOT CHANNEL ESTIMATION OF UPLINK REFERENCE SIGNALS

Abstract:

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a mobile station may transmit first uplink reference signals in a first time slot. The mobile station may transmit an uplink communication with a frequency domain resource allocation different than a frequency domain resource allocation for the first uplink reference signals. The mobile station may determine a time gap between the transmitted uplink communication and second uplink reference signals to be transmitted in a second time slot and retune the mobile station during the time gap such that the second uplink reference signals maintain phase continuity with the first uplink reference signals. The mobile station may transmit the second uplink reference signals in the second time slot. The first time slot and the second time slot may be consecutive time slots for uplink reference signals. Numerous other aspects are described.
