Abstract: An apparatus for a beamformee and a method are provided. The apparatus includes a first beamforming matrix device configured to generate a first beamforming matrix VWB from a channel H; an equivalent channel device configured to generate an equivalent channel {tilde over (H)}k based on the channel H and the first beamforming matrix VWB, where k is a number that indicates a subcarrier index; a second beamforming matrix device configured to obtain a second beamforming matrix VSC from the equivalent channel {tilde over (H)}k; and a transmitter configured to transmit the first beamforming matrix VWB and the second beamforming matrix VSC.

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 method and device are provided for dynamic access point (AP) selection by a coordinator in a coordinated AP group. The coordinator of the coordinated AP group receives one or more link quality metrics for each link between a station (STA) and each of a plurality of member APs in the coordinated AP group, from the plurality of member APs. The coordinator selects an anchor AP for the STA from the plurality of member APs based on the one or more link quality metrics for each link. The anchor AP is used to relay transmissions between the STA and the coordinator. Authentication of the STA with the 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.
