RESTRICTED TWT WITH ENHANCED MULTI-LINK SINGLE RADIO (EMLSR) OPERATION - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18343060 Titled 'RESTRICTED TWT WITH ENHANCED MULTI-LINK SINGLE RADIO (EMLSR) OPERATION'
Simplified Explanation
The abstract describes a system where multiple devices called STAs are connected to an AP (Access Point) in a network. These STAs have transceivers to communicate with the AP and processors to handle data. The system establishes a schedule called R-TWT (Restricted Target Wake Time) on one link, where one STA is part of a specific service period. Another STA on a different link is not part of any overlapping service period. The processor then transitions the network into EMLSR (Enhanced Multi-Link Service Reliability) operation, where the first and second links form a pair. It detects when a transmission opportunity (TXOP) starts on the second link and coordinates between the STAs to ensure that a frame exchange sequence with the AP on the second link does not overlap with the R-TWT service period on the first link.
Original Abstract Submitted
A non-access point (AP) MLD comprises STAs, each comprising a transceiver that forms a link with a corresponding AP of an AP MLD, and a processor. A restricted TWT (R-TWT) schedule is established on a first link, and a first STA on that link is a member of an R-TWT service period (SP) on that link. A second STA on a second link is not a member of any R-TWT SP on that link that overlaps with the R-TWT SP on the first link. The processor transitions the non-AP MLD into EMLSR operation wherein the first and second links form an EMLSR link pair, determines that a transmission opportunity (TXOP) has begun on the second link, and coordinates between the STAs such that a frame exchange sequence with the AP MLD on the second link during the TXOP does not overlap with the R-TWT SP on the first link.
