摘要： Methods, apparatuses, and computer readable media include an apparatus of an access point (AP) or station (STA) comprising processing circuitry configured to decode a legacy preamble of a physical layer (PHY) protocol data unit (PPDU), determine whether the legacy preamble comprises an indication that the PPDU is an extremely-high throughput (EHT) PPDU, and in response to the determination indicating the PPDU is the EHT PPDU, decode the EHT PPDU. Some embodiments determine a spatial stream resource allocation based on a row of a spatial configuration table, a row of a frequency resource unit table, a number of stations, and location of the station relative to the number of stations in user fields of an EHT-signal (SIG) field. To accommodate 16 spatial streams, some embodiments extend the length of the packet extension field, extend signaling of a number of spatial streams, and/or extend a number of EHT-SIG symbols.

摘要： Methods, apparatuses, computer readable media for beamforming smoothing and indication in a wireless network are disclosed. An apparatus of a wireless device comprising processing circuitry is disclosed. The processing circuitry is configured to decode a null data packet (NDP). The processing circuitry is further configured to determine beamforming vectors or matrixes from a channel matrix estimate from the NDP, and smooth the beamforming vectors or matrixes. The processing circuitry is further configured to configure the station to transmit feedback, the feedback including the smooth beamfortning vectors or matrixes, and decode a downlink (DL) physical layer convergence procedure (PLCP) protocol data unit (PPDU)(DL PPDU) from the access point where the DL PPDU beamformed based on the smooth beamforming vectors or matrixes.

摘要： Embodiments of an Extremely High Throughput Station (EHT STA) (STA1) configured for operating in a next-generation (NG) wireless local area network (WLAN) are described herein. In some embodiments, the EHT STA encodes a common signal field (SIG) (Coex-SIG) of an EHT PPDU to include a TXOP duration field. The TXOP duration field is more than seven bits to indicate an actual TXOP duration of a transmission from the EHT STA comprising the EHT PPDU transmitted to a second station (STA2). Decoding the TXOP duration field of the EHT PPDU by a third-party station (STA4) causes the third-party station (STA4) to defer a transmission until after an end of the transmission from the second station (STA2).

摘要： An access point (AP) may operate as a master AP (AP1) to perform multi-AP coordinated beamforming (CBF). The AP1 may to initiate a first sounding sequence with one or more STAs associated with the AP1 (BSS STAs) and the one or more STAs associated with a second AP (AP2) (OBSS STAs). In these embodiments, initiation of the first sounding sequence triggers the AP2 to join the sounding sequence to initiate a second sound sequence with the BSS STAs and the OBSS STAs.

摘要： 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.

摘要： This disclosure describes systems, methods, and devices related to enhanced bandwidth selection for wireless devices. A device may generate a request frame with at least one of a first indication of a bandwidth for which a second device is to measure a first noise level or a second indication of a resource unit for which the second device is to measure a second noise level. The device may send the request frame to the second device. The device may identify a response frame received from the second device, the response frame having a third indication of the first noise level or the second noise level and a fourth indication of the bandwidth or the resource unit. The device may determine, based on the first noise level or the second noise level, a parameter associated with a subsequent frame to send to the second device.
