摘要： This disclosure describes systems, methods, and devices related to neighbor awareness networking (NAN) operations in the 6 GHz frequency band. A NAN device may generate a first NAN frame including a first indication of a NAN operation capability, and a second indication of a transmit power of the NAN device. The NAN device may send the first NAN frame and may identify a second NAN frame received from a second NAN device, the second NAN frame including a third indication of the NAN operation capability, and a fourth indication of a transmit power of the second NAN device. The NAN device may determine, based on the transmit power of the NAN device and the transmit power of the second NAN device, an operation parameter for the 6 GHz frequency band. The NAN device may establish, based on the operation parameter, a NAN connection using the 6 GHz frequency band.

摘要： This disclosure describes systems, methods, and devices related to an enhanced hybrid automatic repeat request (HARQ). A device may determine two or more HARQ medium access control (MAC) frames. The device may determine a difference between a first number of bits of a physical layer (PHY) codeword and a second number of bits of a first HARQ MAC frame of the two or more HARQ MAC frames. The device may generate, based on the difference, a third number of bits, wherein the first number of bits is equal to a sum of the second number of bits and the third number of bits. The device may generate an aggregated MAC frame comprising the first HARQ MAC frame, the third number of bits, and a second HARQ MAC frame of the two or more HARQ MAC frames. The device may send the aggregated MAC frame.

摘要： Embodiments of an access point (AP), station (STA) and method of communication are generally described herein. The AP may be configurable to operate as a master AP of a multi-AP group. The master AP may establish the multi-AP group by: transmitting one or more messages to advertise the multi-AP group; and exchanging signaling with one or more of the other APs of the multi-AP group. The signaling may include at least one message related to one of the other APs joining the multi-AP group. The master AP may establish the multi-AP group to enable usage of AP Trigger Frames (AP TFs) for coordination of resources to be used for downlink transmissions of the APs of the multi-AP group.

摘要： This disclosure describes systems, methods, and devices related to group-addressed transmissions in wireless communications. A device may determine a first time associated with a first multicast transmission including a first basic service set (BSS) identifier (BSSID) associated with a first BSS of a multi-BSSID set including the first BSS and a second BSS. The device may send a frame including the first time, the first BSSID, wherein the frame indicates that the second BSS may ignore multicast transmissions at the first time, and wherein the first time is during a beacon interval associated with a beacon addressed to the multi-BSSID set. The device may send the first multicast transmission at the first time and may send a second multicast transmission at a second time, wherein the second time is during the beacon interval, and wherein the second multicast transmission includes a second BSSID associated with the second BSS.

摘要： Embodiments of a station (STA), access point (AP) and method for determination of transmit power for spatial reuse are generally described herein. The STA may detect, in the channel, an overlapping basic service set (OBSS) physical layer convergence procedure protocol data unit (PPDU) from an OBSS AP. The STA may determine, based at least partly on an ESS color parameter included in the OBSS PPDU, whether the OBSS AP is included in the ESS network. The STA may determine an OBSS power threshold based at least partly on whether the OBSS AP is included in the ESS network. The STA may determine, based at least partly on a comparison between the OBSS power threshold and a received power of the OBSS PPDU, whether to transmit an uplink PPDU to the BSS AP in the channel during the TXOP.

摘要： Methods, apparatuses, computer readable media for spatial reuse for uplink multi-user transmissions. An apparatus of a station comprising processing circuitry is disclosed. The processing circuitry may be configured to decode a first portion of a physical layer convergence procedure (PLCP) protocol data unit (PPDU), and configure the station to transmit a frame, if the PPDU is an overlapping basic service set (OBSS) PPDU, and a receive power of the PPDU is below an overlapping power detect level. An apparatus of an access point comprising processing circuitry is disclosed. The processing circuitry may be configured to encode a PPDU comprising a basic service set identifier of the access point, and encode the PPDU to indicate spatial reuse (SR) delay, SR restricted, or SR not permitted. The processing circuitry may be further configured to configure the access point to transmit the PPDU.
