Title:
METHOD AND APPARATUS FOR NSTR OPERATION WITH MULTIPLE TWT OVER MULTIPLE LINKS
Document Type and Number:
WIPO Patent Application WO/2023/172117
Kind Code:
A1
Abstract:
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.
