  • Patent number: 11690012
    Abstract: Systems and methods for managing use of power of a wireless communication device configured to communicate over a plurality of radio links. A criterion is detected, and one of the plurality of radio links is selected as a selected radio link based on detecting the criterion. Operation of the selected radio link is switched from a first operating mode to a second operating mode, and operation of one or more remaining radio links of the plurality of radio links is disabled. In response to switching operation of the selected radio link to the second operating mode, the selected radio link oscillates between an awake state and an asleep state. Radio traffic information for the plurality of radio links is received, via the selected radio link, during the awake state.

  • Publication number: 20220167265
    Abstract: A method and device are provided for dynamic access point (AP) selection by a coordinator in a coordinated AP group. The coordinator of the coordinated AP group receives one or more link quality metrics for each link between a station (STA) and each of a plurality of member APs in the coordinated AP group, from the plurality of member APs. The coordinator selects an anchor AP for the STA from the plurality of member APs based on the one or more link quality metrics for each link. The anchor AP is used to relay transmissions between the STA and the coordinator. Authentication of the STA with the anchor AP is shared with all APs in the coordinated AP group, allowing the STA to utilize any subsequently selected anchor AP to relay transmissions without re-authentication.
