  • Publication number: 20230269788
    Abstract: An adaptive set of RTA Adaptive EDCA rules and structures are provided to allow non-AP STAs to transmit RTA packets inside a R-TWT SP. The RTA Adaptive EDCA Parameter Set can be selected in response to receiving a trigger from the associated AP, or by pre-configuration. Non-AP STAs, as R-TWT member or non-member of the current R-TWT SP, can switch from using the regular EDCA parameters to the new RTA Adaptive EDCA parameters inside the R-TWT SP. Various rules are described for duration of use, while the AP can prevent STAs from using the new RTA Adaptive EDCA at any time inside of the R-TWT SP.

  • Publication number: 20230262770
    Abstract: Wireless IEEE 802.11 communication mechanisms are described for a member STA of a R-TWT SP to gain TXOP channel access before the R-TWT SP, which does not need to end before the start time of the R-TWT SP. On trigger based R-TWT SP, the TXOP time is shared to overlap the R-TWT SP; allowing the AP to behave as the TXOP holder for the frame exchange of latency sensitive traffic during the R-TWT SP. Thus, the R-TWT scheduling AP and member STAs of a R-TWT SP can contend for the channel together before the scheduled start time of the R-TWT SP. When one of these STAs gains channel access, it can reserve a TXOP until the scheduled end time of the R-TWT SP, which may extend beyond the normal TXOP limit.

  • Publication number: 20230262769
    Abstract: In a MU-RTS TXS based P2P access allocation, there can be frames sent in legacy format (such as control frames in non-HT format) that do not carry a Basic Service Set Identification (BSSID) in its address fields. The Duration setting of the frames may cause a next station to be scheduled to set the basic NAV because the next station categorizes these frames as inter-BSS PPDUs. To prevent the next station from not responding to the AP's next allocation, the Duration setting of the frames are set so that they are not greater than the end time of the P2P allocation that occurs prior to the next allocation.

  • Publication number: 20230254897
    Abstract: An enhanced method of handling block Acks, such as for latency sensitive traffic streams, for which a separate block Ack mechanism is established, which is separate from other traffic in the same TID. With this separate block Ack mechanism the recipient STA can have an independent receive reordering buffer control for latency sensitive traffic, so that the MSDU or A-MSDU of latency sensitive traffic can be passed to the next MAC process in order of increasing sequence number of the MSDUs or A-MSDUs since those MSDUs and A-MSDUs have the same QoS requirement, such as the latency time. This mechanism reduces the chances of latency sensitive traffic being stuck in a receive reordering buffer behind other traffic in the TID and having its traffic expire.

  • Publication number: 20230199846
    Abstract: A wireless communication apparatus, method or protocol for wireless STAs using CSMA/CA on a wireless local area network (WLAN). A receiver STA receives MSDUs or A-MSDUs which include an expiration time, from a transmitter STA. The receiver STA stores the MSDUs or A-MSDUs with expiration time in its receive reordering buffer of the corresponding high-throughput (HT)-immediate block acknowledgement (Ack) agreement. The receiver STA passes the MSDU or A-MSDU to a next MAC process before an expiration time of the MSDU or A-MSDU. Thus, the percentage of latency sensitive traffic packets being communicated prior to expiration is increased.

  • Publication number: 20230199847
    Abstract: Enhanced R-TWT scheduling is performed in which the R-TWT scheduling AP can perform scheduling quickly to react quickly to changes in the network environment and optimize R-TWT scheduling for efficiency and stability. The R-TWT scheduling AP transmits R-TWT trigger frames and is able to collect information from R-TWT scheduled STAs which may affect R-TWT scheduling. The scheduling can take into account that some member STAs may be dozing (asleep) for several beacon intervals and do not wake up for the beacon, then the R-TWT scheduling AP initiates the update of parameters when needed to check on those STAs to determine if any updates are needed. The R-TWT trigger frame can allocate resource units (RU) for R-TWT scheduled STAs to communicate back to the R-TWT scheduling AP.

  • Publication number: 20230199844
    Abstract: A wireless IEEE 802.11 communication protocol under CSMA/CA for enhanced full duplex (FD) station (STA) operations. PPDU preambles are configured to incorporate STA identification and corresponding resource unit (RU) or multiple resource unit (MRU) information. An FD AP indicates STA identification and corresponding RU/MRU index of a transmission destination in the FD preamble of a downlink (DL) PPDU; while a FD non-AP STA indicates its own STA identification and corresponding RU/MRU index in the FD preamble of a uplink (UL) PPDU. The disclosed technology mitigates many issues in regard to fake collisions, partial RU fake collisions, and real collisions, toward improving communications and efficiency and reducing latencies.

  • Publication number: 20230199845
    Abstract: A wireless communication protocol which operates with multi-link devices (MLDs) having simultaneous transmit and receive (STR) link pairs to allow transmitting a long MU PPDU by an originator on a first link, which is acknowledged (Ack) by a recipient on a second link. The Ack on the second link may be on a single resource unit (RU) which may be shared by multiple stations. The Ack may be received during the MP PPDU on the first link, making it a quick Ack. In many cases this allows the originator to perform a retransmission within the same PPDU, thus especially benefitting real-time traffic which is latency sensitive.

  • Publication number: 20230199647
    Abstract: New reverse direction (RD) protocols for EHT devices during reserved target wait time (R-TWT) service periods (SPs). In this protocol the R-TWT scheduling AP does not have to trigger the RD initiator when it performs as the RD responder, and can trigger TB PPDU(s). In addition, the RD initiator is enabled to inform the RD initiator to inform its non-AP peer STA about the R-TWT information in the transmitted RD PPDU. The RD initiator is enabled to send a new MU RD PPDU to both the R-TWT scheduling AP and the non-AP peer STA, which allows the AP to quickly takeover scheduling if the non-AP peer STA is a non-RTWT member and has limited access the in current ongoing R-TWT SP.

  • Publication number: 20230156687
    Abstract: A non-AP STA, which is a scheduled STA having membership in an R-TWT scheduled STA, having an enqueued urgent burst of RTA traffic for the AP during an ongoing R-TWT SP of which it does not have R-TWT membership, is enabled to initiate R-TWT negotiation with the scheduling AP inside the ongoing R-TWT SP to either request a temporary or a long-term membership of the current ongoing R-TWT SP or request to setup a new temporary or long-term R-TWT SP after the current SP, but before the SP it originally had membership in, or to contend for an RA-RU in the current R-TWT SP if UORA feature is enabled. Thus, a non-R-TWT member STA is granted access for its burst traffic transmissions.

  • Publication number: 20230122711
    Abstract: Method and apparatus for supporting simultaneous MultiUser (MU) Multiple-Input Multiple-Output (MIMO) operations utilizing Orthogonal Frequency Division Multiple Access (OFDMA) with Uplink OFDMA Random Access (UORA). Access Points (APs) trigger and obtain short PPDUs from the stations to learn spatial filtering patterns that are utilized in adjusting antenna phase differences to obtain minimum/maximum energy from this BSR. The APs determine favored and unfavored directions of communication, which are conveyed to non-AP UORA stations as channel estimation signals. The UORA stations base broadcasting on strengths of channel estimation signals to determine eligible UORA resource units. The UORA procedure to secondary APs allows a primary AP to trigger a UL-MU MIMO transmission with the number of spatial streams exceeding the number of antennas at the primary AP.
