    Abstract: Methods and a devices are provided is for receiving simultaneous downlink transmissions at a mobile station (STA). Information regarding whether endings of simultaneous data transmissions to the mobile station are to be aligned is transmitted to an access point (AP). The simultaneous data transmissions are between the AP and the STA over a pair of channels. Reception begins of a first data transmission, from the AP, on a first channel of the pair of channels. Reception begins of a second data transmission, from the AP, on a second channel of the pair of channels. The second data transmission overlaps at least a portion of the first data transmission. Reception of the second data transmission ends upon an end of the first data transmission when the information indicates that the endings of simultaneous downlink data transmissions are to be aligned.

    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: A system and method for the discovery of Access Point Stations operating on non-Preferred Scanning Channels. In some embodiments, the method includes: receiving, by a non-Access Point Station (non-AP STA), from a first Access Point Station (AP STA), in a transmission on a first channel, a Reduced Neighbor Report (RNR); and determining, by the non-AP STA, from the RNR, that a second AP STA is operating on a second channel, the first channel being a Preferred Scanning Channel (PSC), and the second channel being a non-PSC channel.

    Abstract: A system and method for dynamic access point (AP) selection by a station (STA) in a coordinated AP group is herein disclosed. According to an embodiment, a STA obtains one or more link quality metrics for each link between the STA and each of a plurality of member APs in the coordinated AP group. The STA dynamically selects at least one anchor AP for the STA from the plurality of member APs based on the one or more link quality metrics for each link. The at least one anchor AP being used to relay transmission between the STA and a coordinator of the coordinated AP group. Authentication of the STA with the at least one anchor AP is shared with all APs in the coordinated AP group, allowing the STA to utilize any subsequently selected anchor AP to relay transmissions without re-authentication.

    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.
