  • Publication number: 20220225200
    Abstract: Seamless client roaming for Multi-Link Device (MLD) clients may be provided. First, a Traffic Identifier (TID)-to-link map may be established by an Upper Service Access Point (U-SAP) of a multi-AP MLD entity that assigns subsets of TIDs to at least two links of the entity. For example, a client device logically associates with the U-SAP, while the client device physically connects to a first and second AP of the entity on a respective first and second link, where the first and second AP include first and second Lower Service Access Points (L-SAPs) and are non-collocated. Next, using the map, data received at the U-SAP is directed over one of the two links for transmission to the client device. Further, frame aggregation and block acknowledgment functions may be performed by one of the first or second L-SAP based on whether data transmission is over the first or second link.

  • Patent number: 11387977
    Abstract: A wireless access point device is full-duplex capable and serves wireless communication for at least first and second wireless client devices. The wireless access point device sends to the first wireless client device a trigger frame that causes the first wireless client device to send an uplink transmission to the wireless access point after a first time interval. The wireless access point device waits a second time interval after the first wireless client is expected to begin sending the uplink transmission. The wireless access point device receives the uplink transmission from the first wireless client device. After the second time interval, and while receiving the uplink transmission from the first wireless client device, the wireless access point device sends to the second wireless client device a downlink transmission that overlaps at least partially in frequency and time with the uplink transmission from the first wireless client device.

  • Publication number: 20220150724
    Abstract: A method is provided in which an AP of a MLD AP device may decide to include all out-of-link BSS parameters updates in a beacon frame (beacon). A flag is included in the beacon frame to indicate that all updates are included in the beacon frame and thus the client device that receives the beacon frame should not send probe request frames (probe requests) to obtain these updates. Thus, a non-AP MLD that receives a beacon frame with the above indication and that has all critical BSS parameters corresponding to the Change Sequence Number (CSN) that preceded the updates indicated by the AP, should not send probe requests to obtain the updated parameters. The number of bits to assign to the complete BSS Update Report Indication flag may vary depending on the number of updates to be reported.

  • Publication number: 20220086661
    Abstract: Aspects described herein include an exclusionary approach for basic service set (BSS) color selection and assignment in a network. A network controller for a network selects a radio associated with an access point (AP) under management of the network controller and determines a potential set of BSS colors for the radio. The network controller then removes/excludes a set of BSS colors that impacts the radio from the potential set of BSS colors and updates or assigns a BSS color for the selected radio using the potential set of BSS colors, minimizing the chances that the assigned BSS color will cause an overlapping BSS color condition in the network.

  • Publication number: 20220086808
    Abstract: In dense Wireless Local Area Network (WLAN) deployments, Access Points (APs) in other Extended Service Sets (ESSs) can be hidden (a first AP does not receive signals from a third AP). However, these APs in other ESSs can still interfere with communications between the third AP and the devices communicating with the first AP. To improve service to that device in that situation, the first AP needs information about the third AP in the first AP's decision making processes. In these situations, a second AP, in contact with the third AP, can share information about the third AP with the first AP so that the first AP can avoid colliding with the third AP.

  • Publication number: 20220070773
    Abstract: In one embodiment, a first wireless access point (AP) of a first basic service set (BSS) receives, from a second wireless AP of a second BSS, data indicative of an 802.11-based target wake time (TWT) schedule of a client of the second BSS. The first wireless AP identifies, from the receive data, a scheduled communication time of the client of the second BSS in the TWT schedule. The first wireless AP generates an 802.11-based TWT schedule for a client of the first BSS that avoids the scheduled communication time of the client of the second BSS. The first wireless AP sends the generated 802.11-based TWT schedule to the client of the first BSS, wherein the sent TWT schedule causes the client of the first BSS to wake from sleep at a scheduled wake time.

  • Publication number: 20220061044
    Abstract: Bypassing radar in wide Dynamic Frequency Selection (DFS) channels utilizing puncturing may be provided. A first client device may be classified as eligible for puncturing and a second client device may be classified as not eligible for puncturing. Next, it may be determined that a subchannel in a bandwidth range should not be used. Then, in response to determining that the subchannel in the bandwidth range should not be used, the first client device may be steered to a first subset of the bandwidth range and the second client device may be steered to a second subset of the bandwidth range. The second subset of the bandwidth range may be smaller than the first subset of the bandwidth range.
