Abstract: A system and a method are disclosed for implementing power saving protocols for devices in a wireless communication system. A method performed by an AP is provided, which includes transmitting, to a STA, a first message indicating a power save schedule of the AP; and transitioning, during a scheduled time window, from an awake state to a reduced power state, based on the power save schedule. The reduced power state is associated with a power state transition capability.

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: Methods and apparatuses are provided in which an access point (AP) transmits a trigger frame to one or more user equipments (UEs). The trigger frame includes an indication of allocated resource units (RUs) for random access (RA). A UE allocates respective data to a sets of RUs for RA that are consecutive in a single frequency segment over a time domain of a physical protocol data unit (PPDU), based on the trigger frame. The UE transmits the PPDU to the AP.

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: 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.
