Abstract: A method of implementing a hybrid automatic repeat request (HARQ) process. The method includes: transmitting, by a transmitter to a receiver, an initial transmission of the HARQ process; receiving, by the transmitter from the receiver, receiver decoding capability information; setting, by the transmitter, a retransmission duration based on the receiver decoding capability information; and implementing, by the transmitter, a retransmission of the HARQ process based on the retransmission duration.

Abstract: A method and system for providing sub-band whitening are herein provided. According to one embodiment, a method estimating an interference whitening (IW) factor based on a legacy-long training field (LLTF) signal, updating the estimated IW factor during transmission of a data symbol, and scaling the data symbol based on the updated IW factor and the estimated IW factor.

Abstract: A method of implementing a hybrid automatic repeat request (HARQ) process. The method includes generating a HARQ transmission that comprises one or more HARQ units by: determining a HARQ unit size of the one or more HARQ units; generating the one or more HARQ units by assigning to each respective HARQ unit, based on the HARQ unit size, at least a respective portion of a media access control (MAC) layer data unit; and generating a header for the HARQ transmission. The method further includes transmitting the HARQ transmission to a receiver. The one or more HARQ units are physical layer data units.

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 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.
