    Abstract: This disclosure describes systems, methods, and devices related to enhanced transmission. A device may generate an aggregated medium access control protocol data unit (A-MPDU) frame, wherein the A-MPDU is associated with transmission of n Network Coding (NC) encoded frames. The device may divide the A-MPDU frame into k data frames and (n?k) parity frames within the A-MPDU frame. The device may transmit the k data frames. The device may transmit to a station device (STA) at least one of the (n?k) parity frames separately after the data frames in response to packet drops in the k data frames.

  • Patent number: 11863473
    Abstract: Embodiments of an access point (AP), station (STA) and method of communication are generally described herein. The STA may determine a portion of a channel occupied by an incumbent device. The STA may refrain from communication in a first subset of resource units (RUs) that overlap the portion of the channel occupied by the incumbent device. The STA may determine a combined RU that comprises two or more RUs of a second subset of RUs that do not overlap the portion of the channel occupied by the incumbent device. The STA may encode a physical layer convergence procedure protocol data unit (PPDU) for transmission in the combined RU. The PPDU may be encoded in accordance with joint coding across the RUs of the combined RU.

  • Patent number: 11716121
    Abstract: An access point (AP) configured for multi-AP coordinated beamforming (CBF) and multi-AP joint transmission (JT) in an Extremely High Throughput (EHT) wireless local area network (WLAN), when operating as a master AP (AP1) in a multi-AP network, is configured to encode a null data packet announcement (NDPA) frame for multi-AP channel sounding. The NDPA is configured for transmission to a second AP (AP2) and a plurality of stations (STAs) of an EHT group. The NDPA may be encoded to have an information field indicating whether a sounding sequence type is for JT channel sounding or CBF channel sounding. The NDPA may further be encoded to include fields identifying the APs participating in the channel sounding. In these embodiments, the channel sounding sequence for JT can be reused for the channel sounding on CBF.
