  • Patent number: 10892863
    Abstract: Embodiments of an access point (AP), station (STA) and method of communication are generally described herein. An AP may be configurable to operate as a master AP of a multi-AP group comprising the master AP and one or more satellite APs. The master AP may select, from the multi-AP group, a set of APs that is to communicate with a STA in accordance with joint processing. The master AP may allocate one or more spatial streams to each of the APs of the set of APs for a joint transmission of a null data packet (NDP) to the STA for channel sounding. The master AP may transmit an NDP announcement (NDPA) that indicates that the APs of the set of APs are to perform the joint transmission of the NDP.

  • Publication number: 20200403680
    Abstract: Methods, apparatuses, and computer readable media for channel state information for multiple access points are disclosed. Channel station information (CSI) may be coordinated for multiple access points (APs) where one AP may act as a master AP with other AP acting as slave APs. The channel station information may be based on information from null data packets received by stations from multiple-APs, which may enable a multi-AP coordinated beamforming (CBF) to be determined based on the received first CSI reports. New frame formats are disclosed that include fields for including APs. Overlapping basic service set (OBSS) stations may respond to APs that are not within their BSS. Some embodiments relate to passive range finding in a multi-AP sounding where location configuration information (LCI) changes for one of the APs.

  • Publication number: 20200396568
    Abstract: This disclosure describes systems, methods, and devices related to group addressed data delivery. A device may determine a plurality of links between one or more access points (APs) in an AP multi-link device (MLD) and one or more logical non-AP stations (STAs) in a non-AP MLD. The device may determine one or more group addressed frames to be sent from the one or more APs of the AP MLD to the one or more non-AP STAs of the non-AP MLD. The device may generate a delivery traffic indication map (DTIM) associated with each link to be used by the one or more non-AP STAs of the non-AP MLD to receive group addressed frames. The device may perform an action based on whether the non-AP MLD sent an indication that a first link of the plurality of links is selected by the non-AP MLD for receiving a first group addressed frame from the one or more group addressed frames.

  • Patent number: 10863544
    Abstract: Methods and devices are described for providing wireless stations (STAs) with two sets of enhanced distributed channel access (EDCA) parameters. Legacy EDCA parameters that are for single user (SU) operations and may be used by both high-efficiency (HE) STAs and legacy STAs without multi-user (MU) capability. MU EDCA parameters are defined to be more restrictive than legacy EDCA parameters in favoring MU operations. Embodiments are described that define sets of rules for regulating how STAs capable of both SU and MU uplink operations can use the different sets of EDCA parameters.

  • Patent number: 10863373
    Abstract: Described are methods and devices for increasing the efficiency of Wi-Fi networks by increased spatial reuse, which refers to sharing the same wireless spectral resources over different spatial regions. A described technique for doing this is for a Wi-Fi device to increase the threshold of the clear channel assessment (CCA) so as to ignore and regard as interference the transmissions from other devices. The sensing range of the Wi-Fi device then decreases, and the spatial resource can be reused by different Wi-Fi devices in different spatial locations.

  • Patent number: 10798555
    Abstract: Described herein are mechanisms to inform a first Neighbor Awareness Networking (NAN) device as to whether or not a second NAN device is connected to a dynamic frequency selection (DFS) master and/or whether the second NAN device is listening to the same DFS master as the first NAN device. In order for NAN client devices to operate in the 5 GHz band and be DFS compliant, all such devices that are communicating in a NAN peer-to-peer manner must either maintain association with a DFS master or must listen to the same DFS master for channel information.

  • Publication number: 20200305103
    Abstract: Systems, methods, and devices related to an EHT multi-AP group are described. The coordinated APs of the EHT group are synchronized to the coordinator AP using a periodic or non-periodic frame. Each coordinated AP then synchronizes STAs associated with the coordinated AP. In response to an MPDU, either triggered by a trigger frame from the coordinator AP or initiated by the STA, an ACK frame or NDP response is sent by each AP receiving the MPDU. The response to the MPDU is dependent on whether frame aggregation is used, as well as whether the trigger frame triggers transmission of MPDUs from multiple STAs.
