  • Patent number: 10849159
    Abstract: This disclosure provides systems, methods, and apparatuses for allocating wireless resources to a multiple basic service set identifier (BSSID) set including a number of BSSIDs each associated with a corresponding one of a number of access points (APs). An AP may allocate random access resources for use by stations belonging to the multiple BSSID set using a number of association identifier (AID) values based on a group AID mapping contained in a partial virtual bitmap of a traffic indication map (TIM) element. The AP may transmit a trigger frame containing the number of AID values to the stations belonging to the multiple BSSID set.

  • Patent number: 10827359
    Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for enabling a neighboring access point (AP) to reuse communication resources that are used by an existing spatial reuse group (SRG). In one aspect, an SR element including SR information can be generated. The SR information may indicate that a first group of STAs associated with a second AP may reuse resources of a wireless medium over which packets are transmitted by a second group of STAs associated with the first AP and may indicate a permitted OBSS threshold value for reuse of the resources over the first AP. In some implementations, a wireless apparatus may transmit the SR element that includes the SR information.

  • Publication number: 20200344006
    Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for implementing a retransmission protocol in a wireless local area network (WLAN). The retransmission protocol may be based on a hybrid automatic repeat request (HARQ) protocol that supports a delayed acknowledgement for a HARQ retransmission based on receiver processing capability. A first WLAN device may determine that a second WLAN device requires more time to process the HARQ retransmission and may transmit a different communication (interlaced within the HARQ process) to either the second WLAN device or a third WLAN device during the time that the second WLAN device is processing the HARQ retransmission.

  • Patent number: 10779315
    Abstract: A wireless station may buffer data associated with one or more traffic identifiers (TIDs), and generate a media access control (MAC) protocol data unit (MPDU) including TID-specific buffer status report (BSR) information. A BSR control field may include an Access Category Identifier (ACI) bitmap and a delta TID parameter indicating a mapping of TID-specific buffer status information to a first and second queue size indicated by the BSR. In some cases, the MPDU may also include a quality of service (QoS) control field, and queue sizes indicated by the BSR control field and QoS control field may be accumulated for reporting buffer status for a TID. Additionally or alternatively, a transmitting wireless station may generate an aggregated MPDU (A-MPDU) including multiple MPDUs with different A-control fields based on a receiving a capabilities information field indicating a number of different aggregated control (A-Control) fields the receiving wireless station supports.

  • Patent number: 10764877
    Abstract: The present disclosure provides various aspects related to techniques for generating trigger frames, at an AP, that reduce the overhead associated with triggering an uplink transmission from the STA. In some examples, the STA may also calculate its transmit power by decoding a spatial reuse subfield of the trigger frame from the AP and identifying downlink pathloss measurements of the trigger frame. Accordingly, the STA may identify acceptable interference level of the AP and calculate a transmit power in order to minimize interference at the AP. In some aspects, the STA may transmit its uplink packets to a different AP on one or more punctured channels at the calculated transmit power of the STA.
