Abstract: Aspects of the present disclosure provide apparatus and techniques that may be applied in systems that may help enable efficient communication between a base station (BS) and certain devices, such as wearable devices and/or machine type communication (MTC) user equipments (UEs), having a single receiver (RX) for long term evolution (LTE). An exemplary method, performed by a BS, generally includes receiving, from a UE, an indication of a category of the UE, wherein the category of the UE indicates at least one of: a maximum throughput supported by the UE or a number of layers supported by the UE; assuming a number of receivers at the UE based on the category of the UE; determining one or more transmit parameters based on the number of receivers of the UE; and communicating with the UE according to the one or more transmit parameters.

Abstract: 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.

Abstract: 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.
