Abstract: The present disclosure describes a system and method for deconflicting locally administered medium access control addresses (LAMAs). An apparatus includes a memory and a processor communicatively coupled to the memory. The processor receives a request for a client device to use a LAMA and determines that the LAMA is reserved for future use by a first access point. The processor also transmits to the client device a message denying connectivity to the client device using the LAMA.

Abstract: A method includes determining whether a first access point of a plurality of access points and a second access point of the plurality of access points should communicate simultaneously over a shared channel in a first network and in response to determining that one of the plurality of access points won contention of a transmission opportunity for the shared channel, dividing the transmission opportunity into a plurality of time slots. The method also includes scheduling transmissions of the first and second access points into the plurality of time slots according to the determination whether the first and second access points should communicate simultaneously over the shared channel and communicating, to the second access point and over a wired network or a second network different from the first network, an indication of whether the second access point should communicate during a first time slot of the plurality of time slots.

Abstract: Techniques for uplink scheduling in a wireless network are disclosed. A wireless access point (AP) receives, from a wireless station (STA), a buffer status report (BSR) reflecting data accumulated at the STA for uplink to the AP. The AP identifies, based on the BSR, a scheduling mode under which the data was accumulated at the STA. The AP schedules an uplink parameter for the STA, based on the identified scheduling mode. The uplink parameter relates to at least one of: (i) an uplink transmission for the STA or (ii) a buffer status poll for the STA. The AP transmits, to the STA, an allocation relating to the scheduled uplink parameter for the STA.

Abstract: Techniques for dynamic bandwidth expansion are provided. A first set of channel quality metrics is collected, by an access point (AP) communicating using a first bandwidth, for an expanded bandwidth beyond the first bandwidth. A second set of channel quality metrics for the expanded bandwidth is received from one or more stations. An available portion of the expanded bandwidth is then determined based on the first and second sets of channel quality metrics. Communication with the one or more stations is initiated using the available portion of the expanded bandwidth.

Abstract: A method includes receiving, at an access point, a buffer status report from a device wirelessly connected to the access point. The buffer status report indicates a queue depth of the device and a head of line delay for the device. The method further includes scheduling uplink resources at the access point for the device based on the queue depth and the head of line delay.
