Abstract:
A user equipment that supports a first set of beams accumulates transmit power control (TPC) commands to generate an accumulated correction factor during communication between the user equipment and a base station that supports a second set of beams. The user equipment is configured to use a first subset of the first set of beams during the communication and the base station is configured to use a second subset of the second set of beams during the communication. The user equipment detects a change in the first subset or the second subset. The user equipment resets the accumulated correction factor in response to detecting the change. In some cases, the user equipment generates a plurality of correction factors for a corresponding plurality of closed-loop processes. The user equipment resets some or all of the plurality of correction factors in response to detecting the change.
