Disclosed are methods and apparatus for rejecting unreliable downlink (DL) transmit power control (TPC) commands in windup mode. In one aspect, the method includes receiving by a user equipment (UE) a plurality of DLTPC commands from a base station, analyzing on one or more transmitted uplink (UL) TPC commands, detecting a windup mode based on the one or more DLTPC and ULTPC commands, and rejecting one or more DLTPC down commands in the windup mode.

Methods and apparatus for DLTPC rejection in downlink windup mode

Disclosed are methods and apparatus for rejecting unreliable downlink (DL) transmit power control (TPC) commands based on signal-to-interference-ratio estimates (SIRE). The method includes receiving by a user equipment (UE) a DL transmit power control (TPC) command from a base station; calculating a signal-to-interference ratio estimate (SIRE) for the DL channel; determining a scaling factor for a DLTPC rejection threshold based on the DL channel SIRE; adjusting the DLTPC rejection threshold based on the determined scaling factor; and rejecting or accepting the DLTPC command based on the adjusted DLTPC rejection threshold.
