In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may include a memory and at least one processor coupled to the memory. The at least one processor may be configured to determine a retransmission rate associated with retransmission of one or more packets by the communications device. The at least one processor may be configured to determine a measurement associated with antenna gain of at least one antenna of the apparatus. The at least one processor may be configured to adjust a transmission power of the apparatus based on the retransmission rate and based on the measurement.

Mitigating spectral emission conditions for high transmission output power during degraded antenna peak gain

A multiplexer for a device capable of receiving signals in first and second frequency bands, the multiplexer comprising a first branch for connecting an antenna to a first sub-system configured to process received signals in the first frequency band, a second branch for connecting the antenna to a second sub-system configured to process received signals in the second frequency band, wherein the first branch comprises a filter for attenuating received signals in the second frequency band and the second branch couples the antenna directly to the second sub-system.

Multiplexer

An apparatus for amplifying a signal. The apparatus includes an amplifier powered by a power supply, a monitor that monitors an output signal of the amplifier and a controller operative to adjust the power supply if distortion is detected in the output signal of the amplifier by the monitor.
