Abstract: A method, a computer-readable medium, and an apparatus are disclosed for energy efficient multichannel communications. In one aspect, the apparatus may communicate using a plurality of channels working in parallel where the plurality of channels may share an LNA. Additionally, the apparatus may determine a set of parameters for the plurality of channels to maximize energy efficiency. The apparatus may therefore configure the plurality of channels based on the set of parameters. As such, the apparatus supports multichannel communications with a common LNA structure while providing energy optimization for the multichannel communications. Accordingly, multichannel communications can be provided using a shared LNA structure that reduces implementation cost and more efficiently utilizes available power resources.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may tune an auxiliary receiver within a first radio to a transmission frequency of a co-located second radio. The auxiliary receiver may downconvert a signal from the second radio so that the UE may generate an interference estimate and perform interference cancellation. In some cases, the auxiliary receiver may also be used to perform transmission corrections for transmissions of the first radio. For example, the auxiliary receiver may be used to enable gain control or digital predistortion. The auxiliary receiver may be selectively tuned to the transmission frequency of the first radio or the second radio based on whether the auxiliary receiver is being used to perform interference cancellation or transmission correction.
