TID-based communication methods using stream classification services for latency sensitive stream and multilink apparatus

To ease the triggering by an access point multi-link device AP MLD of uplink communications of low latency streams from non-AP MLD, a local traffic stream is identified using a Stream Classification Service, SCS. The local SCS traffic stream is mapped onto a target TID which was previously mapped with an impacted user priority UP. The local SCS stream is preferably assigned to an alternate queue of an access category AC. The impacted UP is also mapped onto a fallback TID, corresponding to the primary queue of the same AC. The SCS stream is advertised to the AP using a SCS Request frame. Conventional fields can be used. A trigger frame from an affiliated AP of the AP MLD may then provide resource units to an affiliated non-AP station dedicated to the target TID, hence specific to the low latency SCS stream.

Communication system

A base station transmits, to a UE (user equipment), via a data radio bearer (DRB), a “dummy” downlink data packet that includes, in the header, information identifying a QoS flow which is mapped to the DRB. The downlink data packet has no user-plane data (an empty payload) and is transmitted prior to transmission, via that DRB, of data packets comprising any downlink user-plane data associated with the identified QoS flow. Reflective QoS flow to DRB mapping enables the UE to map an uplink QoS flow to the appropriate DRB without explicit signaling and before receipt of any downlink data. A user plane entity of a distributed base station determines that a UE has incorrect or does not have QoS flow to DRB mapping information and provides, to a control plane entity, information identifying the QoS flow for which the UE has incorrect or does not have the mapping.

Optimized channel selection for virtual access point (vap) enabled networks

In one embodiment, a supervisory device in a network forms a virtual access point (VAP) for a node in the network. A plurality of access points (APs) in the network are mapped to the VAP as part of a VAP mapping and the node treats the APs in the VAP mapping as a single AP for purposes of communicating with the network. The supervisory device determines a traffic type of traffic associated with the node. The supervisory device assigns the node to a selected wireless channel based in part on the traffic type of the traffic associated with the node. The supervisory device controls the VAP to use the channel assigned to the node.
