  • Publication number: 20230109759
    Abstract: Methods and apparatuses for facilitating recovery from loss of medium synchronization for multi-link devices (MLDs) and renegotiating traffic identifier (TID)-to-link mapping for enhanced multi-link single radio (EMLSR) operation of MLDs in a wireless local area network. A non-access point (AP) MLD comprises STAs, each comprising a transceiver configured to form a link with a corresponding AP of an AP MLD, and a processor operably coupled to the STAs. A subset of the links are EMLSR links that are configured to operate in an EMLSR mode of operation. The processor is configured to generate, based on a determination that an EMLSR frame exchange sequence is occurring on a first one of the EMLSR links, a request for AP-assisted medium synchronization recovery (AAR) for a set of the other EMLSR links. At least one of the transceivers is further configured to transmit, to the AP MLD, the request for AAR.

  • Publication number: 20230103061
    Abstract: Methods and apparatuses for facilitating the coexistence of enhanced multi-link single radio (EMLSR) operation with target wake time (TWT) operation in a wireless local area network. 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.

  • Publication number: 20230074011
    Abstract: Aspects include systems, methods, devices, and non-transitory processor readable storage mediums for managing a broadcast signal of an apparatus for wireless communication. Various aspects may enable an apparatus to send a message using either omnidirectional transmissions or beamformed transmission based on whether the altitude of the apparatus meets an altitude threshold. In some implementations and aspects, the processor of the apparatus may determine a type of the message and may select the altitude threshold based on the determined message type. In some implementations and aspects, the processor of the apparatus may send the message using beamformed transmissions in response to determining that the message is intended for reception by a certain type of second apparatus.

  • Patent number: 11528620
    Abstract: A core network entity (CNE) can predict received signal strength values for base station (BS). In response to a triggering event, the CNE fetches information on BS configuration parameters, including at least one of: a BS class, a BS location, a BS height, an orientation of the BS, a BS antenna pattern, and topographical details surrounding the BS. The BS obtains, processes and forwards to the CNE, measurement reports created by a user equipment (UE) including a signal strength value and a location of the UE. The CNE pools the measurement reports based on the BS class and, in response to another triggering event, recalibrates signal strength prediction tools, which can predict received signal strength values from the BS to a location in a vicinity of the BSs. The CNE also pools and stores the measurement reports and corresponding BS configuration parameters, after post processing and compression.
