Title:
MAP COORDINATION OF NSTR CONSTRAINED LINKS
Document Type and Number:
WIPO Patent Application WO/2023/003323
Kind Code:
A1
Abstract:
Methods and apparatuses for facilitating multi-AP (MAP) coordination to mitigate interference caused by a link of a non-simultaneous transmit/receive (NSTR) link pair of a multi-link device (MLD) in an overlapping basic service set (OBSS) in a wireless local area network. The methods include a method performed by an access point (AP) MLD, comprising the steps of obtaining, via a backhaul link from a neighboring AP in a different BSS, a MAP coordination request that includes schedule information for a victim station (STA) in the different BSS, and modifying, based on the MAP coordination request and the schedule information, an operation mode of either the AP MLD or a non-AP MLD that forms an NSTR link pair with the AP MLD, such that a first link of the NSTR link pair is silenced during an active period of the victim STA.
