One example discloses a method of preemption for latency-sensitive traffic for communications between WLAN (wireless local area network) devices, including: receiving, by an access point (AP), a first frame from a first non-access point station (non-AP STA); transmitting, by the AP, a second frame indicating Transmission Opportunity (TXOP) pre-emption information to the first non-AP STA; and transmitting, to a second non-AP STA, a third frame; wherein the third frame includes latency-sensitive frame.

Disclosed are a random access method and a network device, and a terminal device. The method includes: a terminal device sending first information on a first resource, and sending second information on a second resource; the terminal device detecting third information on one group of third pre-allocated resources in a first window, wherein a start position of the first window comprises: a position after a first time interval after the terminal device sends the second information; or a first time unit after the first time interval after the terminal device sends the second information; or a first time unit in the one group of third pre-allocated resources after the first time interval after the terminal device sends the second information; and the terminal device receiving fourth information on a fourth resource.

A method by which a first device performs wireless communication is proposed. The method may comprise the steps of: determining at least one candidate slot for selecting a sidelink (SL) resource; performing sensing for at least one sensing slot related to the at least one candidate slot; selecting the resource in the at least one candidate slot on the basis of the sensing; and performing SL communication with a second device on the basis of the selected resource. For example, the at least one sensing slot may be at least one slot which, from the at least one candidate slot, is located before a resource reservation period set for a resource pool.

Network traffic interference detection and management may be provided. An infringement event by an infringing Access Point (AP) on a Restricted Target Wake Time (rTWT) transmission opportunity (TxOp) associated with a victim AP may be detected, and information associated with the infringement event may be added to an infringement list, wherein the information includes a MAC address associated with the infringing AP. A controller, may receive the infringement list and notify the infringement event to the infringing AP. The infringing AP may determine whether a transmission associated with the infringement event is low latency and high priority. When the transmission is not low latency and high priority the infringing AP may modify future transmissions based on the notification. When the transmission is low latency and high priority the infringing AP may notify the controller that the transmission is low latency and high priority. The controller may then create a negotiation between the victim AP and the infringing AP, wherein the negotiation comprises managing future transmissions of the victim AP and the infringing AP.

One example discloses a method for low-latency (LL) traffic frame communication between WLAN (wireless local area network) devices, including: sending a trigger frame from an access point (AP) configured to allocate a random access resource unit (RA-RU) to a non-access point station (non-AP STA); wherein the RA-RU enables the non-AP STA to transmit its low latency (LL) traffic information; and receiving, from the non-AP STA, an uplink LL traffic frame using the RA-RU that was allocated.

802.11be wireless networks implement Low Latency Reliable Service measures to prioritize LLRS traffic over conventional not-LLRS traffic. The AP dynamically defines and modifies LLRS traffic configurations made of concerned traffics and associated QoS, through transmission of management frames to the non-AP stations. The AP guarantees the declared QoS applicable to each type of declared traffic profile by scheduling appropriate resources to the LLRS traffic configurations. A monitoring of a correct use of the scheduled resources by the non-AP stations helps avoiding abuses. Plural LLRS traffic configurations can be defined simultaneously within the same frame, using sequential listing or inheritance scheme.
