Abstract: A system and method for downlink feedback in communications between a station and an access point. In some embodiments, the method includes: receiving, from the access point, by the station, a null data packet announcement (NDPA) including a first number of spatial streams, and sending, by the station, to the access point, a Compressed Beamforming Report (CBR) including a second number of spatial streams, different from the first number of spatial streams; or sending, by the station, to the access point, an Operating Mode Indication (OMI) declaring a change in a station Modulation Coding Scheme (MCS) capability for a third number of spatial streams; or sending, by the station, to the access point, an Association Request including a declared Single-User (SU) MCS capability for a first bandwidth and a declared Multi-User (MU) MCS capability for the first bandwidth, the MU MCS capability being different from the SU MCS capability.

Abstract: Systems and methods for providing feedback regarding a wireless communication channel is disclosed. A responding processor is configured to estimate condition of the wireless communication channel and generate a data field. The data field includes a communication parameter based on the estimated condition of the wireless communication channel. The data field is attached to a control frame, and the control frame is transmitted with the attached data field. A transmitting processor is configured to receive the control frame, and determine whether the control frame includes the data field. The transmitting processor retrieves the data field from the control frame, and selects, based on the communication parameter in the data field, a transmit parameter for transmitting data over the wireless communication channel.

Abstract: A method for associating and authenticating a station (STA) with a coordinated access point (AP) group may include generating a pairwise master key (PMK) between the STA and a coordinator of the coordinated AP group, and maintaining an association and authentication state between the STA and the coordinated AP group based on the PMK. The method may further include generating one or more temporal keys between the STA and the coordinator based on the PMK. The method may further include distributing the PMK from the coordinator to a first member AP and a second member AP of the coordinated AP group. The method may further include generating a first temporal key between the STA and the first member AP, and generating a second temporal key between the STA and the second member AP.

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.
