  • Publication number: 20220124857
    Abstract: Certain aspects of the present disclosure provide techniques for handling direct link communications in multi-link systems. An example method generally includes transmitting, to a first wireless station via a direct link between the first wireless station and one or more second wireless stations affiliated with a multi-link device (MLD), a data frame comprising a transmitter address field set to an address of the MLD, which is one of a plurality of addresses associated with the MLD and the second wireless stations being affiliated with the MLD for multi-link operations. The method also includes communicating with the first wireless station via the direct link.
    Type: Application

  • Patent number: 10051558
    Abstract: Methods, systems, and devices for wireless communication are described. An access point (AP) transmits instructions to quiet a dynamic frequency selection (DFS) home channel for a period of time. Instructions can include a quiet information element (IE) or a clear-to-send to self (CTS2Self) frame. The AP then allocates a first dedicated RF chain to a first media access control (MAC) component and a second dedicated RF chain, separate from the first dedicated RF chain, to a second MAC component of the access point. The allocation can include reducing the number of RF chains dedicated to the first MAC component. During the time period determined by the instructions, the first dedicated RF chain scans the home DFS channel and the second dedicated RF chain scans at least one other channel (e.g., based at least in part on the time period and channel scan priority) in the same band as the DFS home channel.

  • Patent number: 9307541
    Abstract: A wireless station (STA) and a method are disclosed that allow the STA to determine suitable characteristics for wireless transmissions from the STA. The STA may receive frames from a number of access points (APs), each frame including a country code indicating a country in which the corresponding AP is located, determine a popularity of each country code by polling the received country codes, determine in which country the STA is currently located based, at least in part, on the determined popularities of the country codes, and select a wireless channel and a transmit power level based, at least in part, on the determined country.
