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 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.

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 providing a mode of wireless local area network (WLAN) operation is disclosed. The method includes: sending an association request from a wireless station (STA) over a discovery channel; receiving an association response at the STA over the discovery channel in response to the association request; and associating the STA to provide a multi-user (MU) enhanced distributed channel access (EDCA) mode using a scheduled access channel.

Abstract: Disclosed is a method of setting conditions for an access point (AP) to be included in an AP candidate set of a coordinating AP for a transmission opportunity (TXOP), including setting a first primary channel of the AP as part of the AP candidate set of the coordinating AP within a basic service set (BSS) operating bandwidth of the coordinating AP, and coordinating AP updates in the AP candidate set when a coordinated AP that is part of the AP candidate set performs a channel switch to a second primary channel operating on a different bandwidth stream than a bandwidth stream of the first primary channel.
