Abstract: A method in a communications device includes: maintaining an association between the communications device and a basic service set identifier; detecting a message at a wireless interface of the communications device; determining whether the message is associated with the basic service set identifier; and when the message is not associated with the basic service set identifier, determining whether to update a timer corresponding to transmission medium availability based on a received signal strength of the message.

Abstract: A method in a communication system including an access point and a plurality of stations, includes: selecting, at the access point, a quasi-omni-directional beam for use in transmitting and receiving control frames to and from the stations; selecting, at each station, one of a plurality of directional beams for use in transmitting and receiving control frames to and from the access point; at each of the stations, pausing transmission of Request To Send (RTS) control frames responsive to detecting (i) a RTS control frame from the access point to any one of the stations, or (ii) a Clear to Send (CTS) control frame from the access point to any one of the stations; wherein pausing transmission of RTS control frames is for a duration of time provided in the detected RTS control frame or CTS frame.

Abstract: A method in a wireless access point (AP) for controlling medium access includes: transmitting a beacon frame defining (i) a beacon header interval (BHI), and (ii) a data transmission interval (DTI) divided into a predetermined number of scheduled periods, each scheduled period containing a set of uplink allocation request sub-periods; sending, to a client device, an uplink allocation request assignment indicating an assigned uplink allocation request sub-period from the set, that corresponds to the client device; during a current one of the scheduled periods, receiving an uplink allocation request from the client device during the assigned uplink allocation request sub-period; determining an uplink allocation sub-period for the client device based on the uplink allocation request; and during a next one of the scheduled periods, sending an indication of the uplink allocation sub-period to the client device.

Abstract: A method in a wireless access point (AP) having an antenna controllable to transmit and receive using a set of AP sectors, includes: transmitting a plurality of beacon instances using each of the AP sectors, each beacon instance associated rotation schedule data defining a plurality of listening time slots corresponding to respective AP sectors; activating a rotating listening mode using the AP sectors in sequence according to the rotation schedule data; in response to detecting a sector sweep initiation message from a client device using an active one of the AP sectors, communicating with the client device to select an AP sector to use in establishing a link with the client device.
