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: The present disclosure provides techniques for Stream Classification Service (SCS) policy validation for downlink and uplink traffic. A network device receives an SCS request from an associated STA, which specifies one or more sets of TCLAS information for a data flow transmitted between the network device and the STA, each set of TCLAS information being accompanied by associated QoS profile information for the data flow. The network device compares the sets of TCLAS information and associated QoS profile information with one or more cached application profiles, and determines that there is no match. In response to the determination, the network device performs packet analysis and confirms that the sets of TCLAS information and associated QoS profile information align with the type of service of the data flow under defined network polices. In response to the confirmation, the network device applies one or more treatments to the data flow.

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.
