  • Publication number: 20230082330
    Abstract: A non-access point (AP) station (STA) may be configured for receipt of a multi-user physical layer protocol data unit (MU-PPDU) with network coding. The STA may decode at least portions of a MU-PPDU received from an access point (AP). The MU-PPDU may comprise a first data portion addressed to the STA, a second data portion addressed to a second STA2, and a parity portion addressed to both the stations. The parity portion may be generated by the AP based on a network coding of the first and second data portions. When the first data portion is received by the STA with errors, the STA may attempt to recover the first data portion using both the parity portion and the second data portion.

  • Publication number: 20230035698
    Abstract: In one example, a transmitter wireless communication device may be configured to encode k data packets into n encoded packets according to a Network Coding (NC) scheme, wherein k is equal to or greater than two, and wherein n is greater than k. For example, the transmitter wireless communication device may be configured to transmit the n encoded packets over a plurality of wireless communication resources, for example, by transmitting at least one first encoded packet over a first wireless communication resource and transmitting at least one second encoded packet over a second wireless communication resource. For example, a receiver wireless communication device may be configured to determine the k data packets, for example, by decoding at least k received encoded packets out of the n encoded packets according to the NC scheme.

  • Publication number: 20230028874
    Abstract: Embodiments disclosed herein are directed to communicating time-critical ultra-low latency (ULL) data using one or more dedicated resource units (RUs). A station (STA) decodes a trigger frame received from an access point station (AP) encoded to indicate resource units (RUs) of an UL PPDU for an uplink multi-user orthogonal frequency division multiple access (UL MU OFDMA) data transmission by a first and a second station STA. The trigger frame may also be encoded to indicate configuration information for a dedicated RU for time-critical ultra-low latency (ULL) UL data. The dedicated RU may be one RU of one or more RUs of the UL PPDU that are reserved for time-critical communications. The STA may encode time-critical ULL UL data for transmission to the AP on the dedicated RU during the uplink MU OFDMA data transmission by the first and second STAs. The time-critical ULL UL data may start at any time during transmission of the UL PPDU.

  • Publication number: 20220416964
    Abstract: Embodiments disclosed herein are directed to communicating time-critical ultra-low latency (ULL) data. An access point station (AP) communicates time-critical ULL data using aggregated MAC Protocol Data Unit (A-MPDU) preemption. When time-critical ULL data for a second associated STA (STA2) becomes available at a medium access control (MAC) layer of the AP during transmission of a physical layer protocol data unit (PPDU) to a first associate station (STA1), the AP may encode the time-critical ULL data in a new A-MPDU subframe for insertion before one of the A-MPDU subframes of the PPDU that has not yet been transmitted. The new A-MPDU subframe may be encoded to include zero-padding to set a size of the new A-MPDU subframe equal to a size of the A-MPDU subframe that has been preempted. The A-MPDU subframes 606 for STA1 may be encoded include a MAC address of the STA1 and the new A-MPDU subframe 608 may be encoded include a MAC address of the STA2.

  • Publication number: 20220408354
    Abstract: Systems and methods of providing a V2X communications are generally described. A geographically-limited, operator-independent mapping table is used that maps between groups of V2X applications each associated with a different application category and a different RAT preferred for the V2X application category. Each grouping is based on fulfillment of one or more KPIs for the associated V2X application category. Multiple RATs are prioritized if able to fulfill the KPIs. The mapping table is modified based on the RATs supported by the V2X UE. Carrier aggregation is used when simultaneous transmission on different RATs is desired.

  • Publication number: 20220400503
    Abstract: An access point station (AP) communicates with a plurality of non-AP stations (STAs) within a synchronized transmission opportunity (S-TXOP). The S-TXOP may comprise an S-TXOP trigger followed by a plurality of S-TXOP slots. The S-TXOP slots may be configured for communication of synchronous data. For communication of small time-critical (TC) packets within the S-TXOP with one or more of the STAs, the AP may configure the S-TXOP for asynchronous ultra-low latency (ULL) transmissions by providing a low-latency channel access opportunity within the S-TXOP.

  • Patent number: 11516757
    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.
