Systems and methods for enhanced power control at a user equipment (UE) under poor channel conditions respective to antenna transmit diversity (ATD) mechanisms are discussed herein. In some embodiments, a UE may reset a transmit power control (TPC) power adjustment value when an ATD antenna switch of the ATD mechanism is performed. In some embodiments, a UE may reduce the value of an ATD hysteresis timer upon determining that a reference signal receive power (RSRP) change on a monitored reference signal that drives a pathloss calculation at the UE exceeds a threshold. In some embodiments, a UE may scale a filtering coefficient of a pathloss calculation mechanism upon determining that an RSRP change on a monitored reference signal that drives a pathloss calculation at the UE exceeds a threshold.
A method of a user equipment (UE), comprising:
An apparatus for a user equipment (UE) comprising:
A non-transitory computer-readable storage medium including instructions that when executed by one or more processors of a user equipment (UE), cause the UE to:
