摘要： Methods and apparatuses for facilitating quality of service (QOS) enhancements to support low latency operations in a wireless local area network (WLAN). A station (STA) comprises a processor and a transceiver operably coupled to the processor. The transceiver is configured to obtain a transmission opportunity (TXOP). The processor is configured to determine that at least a portion of the TXOP will go unused by the STA and handover the unused portion of the TXOP to an access point (AP).

摘要： Methods and apparatuses for prioritization handling for emergency preparedness communication services (EPCS) operation are disclosed. A method for wireless communication performed by a non-access point (AP) device that comprises a station (STA) includes: forming a link with an AP; receiving information associated with emergency preparedness communication services (EPCS) from the AP; determining whether the STA and the AP support an EPCS operation; based on determining that the STA and the AP support the EPCS operation; determining whether the AP supports prioritization for EPCS devices; when the AP does not support prioritization for EPCS devices, performing the EPCS operation; and when the AP supports prioritization for EPCS devices, performing a prioritized EPCS operation, wherein the prioritized EPCS operation comprises prioritization among EPCS devices.

摘要： Methods and apparatuses for prioritization handling for EPCS operation are disclosed. A method for wireless communication performed by a non-AP device that comprises a STA comprises: forming a first link with a first AP of a first AP MLD and a second link with a second AP of a second AP MLD; receiving information associated with EPCS priority access from the first and second APs, determining whether the STA is undergoing a BSS transition from the first AP to the second AP; when the STA is not undergoing the BSS transition from the first AP to the second AP, continuing with a current EPCS priority access; and when the STA is undergoing the BSS transition from the first AP to the second AP, determining a procedure for handling the EPCS priority access associated with the BSS transition from the first AP to the second AP.

摘要： Methods and apparatuses for facilitating the discovery and setup of multiple peer-to-peer (P2P) direct links for P2P communications between peer multi-link devices (MLDs). A first non-access point (AP) MLD comprises first stations (STAs), each comprising a transceiver configured to form a link with a corresponding AP of an AP MLD, and a processor. The processor is configured to generate a first message that includes information indicating that one or more of the links are target links on which the first non-AP MLD intends to establish a P2P direct link with second STAs of a second non-AP MLD, wherein the second STAs are associated with the corresponding AP of the AP MLD on the target links. The transceiver of a first of the first STAs is further configured to transmit the first message to the corresponding AP of the AP MLD over the link.

摘要： Methods and apparatuses for facilitating restricted TWT operation between multi-link devices (MLDs) across multiple links under non-simultaneous transmit/receive (NSTR) constraints. A non-access point (AP) MLD comprises a processor and stations (STAs), each comprising a transceiver configured to form links with APs of an AP MLD. First and second links form an NSTR link pair subject to NSTR constraints. First and second target wake time (TWT) schedules that have first and second TWT service periods (SPs), respectively, and associated first and second sets of traffic identifiers (TIDs), respectively, are established on the first and second links, respectively. The first and second TWT SPs have an overlapping portion. The processor is configured to determine, based on characteristics of the sets of TIDs, scheduling for traffic on the first and second links during the overlapping portion of the TWT SPs such that the NSTR constraints are not violated.

摘要： Methods and apparatuses for supporting buffered group-addressed management frame indication are provided. A method of wireless communication performed by a non-access point (AP) multi-link device (MLD) comprises: receiving, from an AP of an AP MLD, a delivery traffic indication message (DTIM) beacon, the DTIM beacon comprising a traffic indication map (TIM) element; determining, based on the TIM element, whether group-addressed management frames are buffered at one or more other APs of the AP MLD; and prioritizing reception of one or more other DTIM beacons associated with the one or more other APs of the AP MLD based on whether the group-addressed management frames are buffered at the one or more other APs of the AP MLD.

摘要： Methods and apparatuses for enhancing advertisement of restricted target wake time (TWT) schedules by access points (APs) and improving selection of restricted TWT schedules by stations (STAs) in a wireless local area network. A wireless STA apparatus comprises a transceiver and a processor operably coupled to the transceiver. The transceiver is configured to receive, from an AP, a restricted TWT advertisement that includes a restricted TWT schedule and additional information about the restricted TWT schedule. The processor is configured to determine, based on the additional information, whether to refrain from requesting to become a member of the restricted TWT schedule.

摘要： Methods and apparatuses for facilitating the use of stations (STAs) of a multi-link device (MLD) to set up and operate backhaul links to serve a Mobile access point (AP) within the same MLD in a wireless local area network. The apparatuses include an MLD comprising APs forming a Mobile AP MLD, backhaul STAs, and a processor operably coupled to the APs and the backhaul STAs. The processor is configured to instruct at least one of the APs to set up an access link with a corresponding STA of a non-AP MLD, and to instruct at least one of the backhaul STAs to set up a backhaul link with a corresponding AP of an AP MLD to carry traffic of the non-AP MLD that flows through the Mobile AP MLD over the access link.

摘要： Embodiments of the present disclosure provide methods and apparatuses for obtaining timing information and performing a time offset adjustment for target wake time (TWT) operations in a wireless network. The apparatuses include a first communication device comprising a transceiver and a processor operably coupled to the transceiver. The transceiver is configured to transmit, during a target wake time (TWT) setup phase, a TWT element including a request for information on a traffic delay of a second communication device and receive the information on the traffic delay. The processor is configured to determine a time offset to adjust a start time of a next TWT interval based on the information on the traffic delay.
