Abstract: A method for allowing wireless communication between an access point and a wireless station in a wireless communication network includes: providing at least one from a combination of a 2.4 GHz frequency band and a 5 GHz frequency band; providing a frequency band including a 6 GHz frequency band for allowing wireless data communication; assigning a first data communication channel having a first frequency bandwidth in the frequency band including the 6 GHz frequency band between the access point and the wireless station; and transmitting data packets between the access point and the wireless station via the first data communication channel in the frequency band including the 6 GHz frequency band. Each of the 2.4 GHz frequency band and the 5 GHz frequency band includes a plurality of subchannels having a first base frequency bandwidth of 20 MHz, and the frequency band including the 6 GHz frequency band includes a plurality of subchannels having a second base frequency bandwidth that is larger than the first base frequency bandwidth.

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

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.
