Abstract: A wireless device may determine the level of interference mitigation appropriate for the application and dynamically select a combination of interference cancellation components that satisfies that level. The combination of interference cancellation components may include components that consume power (e.g., active components) and components that do not consume power (e.g., passive components). The interference cancellation components may be used at the transmitter and/or the receiver. In some cases, the wireless device may also determine how much power is acceptable to expend on the interference mitigation. In such scenarios, the selection of the interference cancellation components may be such that the aggregated power consumption is less than the power expenditure limit.

Abstract: Methods in a multiple-cell cellular network that implements iterative coordinated beamforming (I-CBF) algorithms with limited cooperation from adjacent nodes (base stations and/or mobile stations) may jointly determine transmit beamforming vectors and receive combining vectors to increase sum throughput. The transmit beamforming vectors and receive combining vectors can be determined based on a performance metric, such as by maximizing SINR (signal-to-interference-and-noise ratio) for each mobile station in the network, maximizing SLNR (signal-to-leakage-and-noise ratio) for each base station in the network, or minimizing SMSE (sum mean square error). The algorithms may be performed to update vectors synchronously. In other cases, the algorithms may be performed to update vectors asynchronously.

Abstract: A device may use enhanced power amplifier (PA) linearization techniques such as adaptive feed-forward (FF) linearization using adaptive filters. In one example, an adaptive feed-forward linearizer may isolate a distortion signal based at least in part on the signals input to and output from a PA in a transmission path. The distortion signal may be used to cancel distortion at the output of the PA to produce an improved output signal. A first adaptive circuit may be used to produce the distortion signal and a second adaptive circuit may be used to produce an error cancellation signal based at least in part on the distortion signal. The error cancellation signal may be amplified and re-introduced to the transmission path to produce the improved output signal. Semi-adaptive circuits may be used in place of the adaptive circuits, or a hybrid approach may be used.
