Abstract: A method for communicating over a WiFi channel. In some embodiments, the method includes determining, by a non-access point station, that a first skipping criterion is met; in response to determining that the first skipping criterion is met, skipping N1 target wait time service periods, N1 being a positive integer; after skipping N1 target wait time service periods, determining, by the non-access point station, whether a second skipping criterion is met; and in response to determining that the second skipping criterion is met, skipping N2 subsequent target wait time service periods, N2 being a positive integer greater than N1.

Abstract: A method in a wireless station in communication with an access point over a communication channel includes receiving a channel estimation matrix; determining a beamforming matrix using the channel estimation matrix, the beamforming matrix being generated for a plurality of down-sampled feedback indices; the beamforming matrix including beamforming weights for one or more antennas associated with the access point, each beamforming weight being a complex value including an amplitude and a phase; setting the phase of the beamforming weight for a last antenna associated with the last feedback index of the beamforming matrix to zero and rotating the phase of each beamforming weight for each of the other antennas; performing smoothing of the beamforming matrix for each feedback index by normalizing each column vector of the beamforming matrix; compressing the smoothed beamforming matrix; and providing the smoothed beamforming matrix as output.

Abstract: Systems and methods for managing use of power of a wireless communication device configured to communicate over a plurality of radio links. A criterion is detected, and one of the plurality of radio links is selected as a selected radio link based on detecting the criterion. Operation of the selected radio link is switched from a first operating mode to a second operating mode, and operation of one or more remaining radio links of the plurality of radio links is disabled. In response to switching operation of the selected radio link to the second operating mode, the selected radio link oscillates between an awake state and an asleep state. Radio traffic information for the plurality of radio links is received, via the selected radio link, during the awake state.
