摘要： A station (STA) may operate as a first peer-to-peer (P2P) client (P2P1) for P2P operations with dual-stage triggering. The STA may decode a primary frame trigger frame (TF) from an access point (AP) operating as a coordinator. The primary TF may allocate resources in an initial portion of a time-duration allocation to the P2P1 for the P2P operations with one or more other peer stations, including a second P2P client (P2P2) and a third P2P client (P2P3). The primary TF may further allocate resources in a subsequent portion of the time-duration allocation to the P2P2 for the P2P operations. The STA may also encode a first secondary TF for transmission within the initial portion of the time-duration allocation. The first secondary TF may allocate specific resource units (RUs) to the one or more other peer stations. The STA may also decode a TB physical layer protocol data unit (TB PPDU) encoded in accordance with a multi-user orthogonal frequency division multiple access (MU OFDMA) frame format. The TB PPDU may be received concurrently within the initial portion of the time-duration allocation from the one or more other peer stations in accordance with an uplink OFDMA technique.

摘要： An access point (AP) is configured for trigger-based peer-to-peer (TB P2P) operation with at least two peer stations (P2P1) and (P2P2) in which the AP (API) is operating as a coordinator. The AP may be configured to encode a trigger frame (AP TF) for transmission to reserve channel resources for two or more P2P transfers and identify times for each of the P2P transfers and may indicate an allocation of channel resources to a first of the peer stations (P2P1) for a first of the P2P transfers and to a second of the peer stations (P2P2) for a second of the P2P transfers. During the allocation for the first P2P transfer, the AP may decode a null data packet (NDP) frame for channel sounding received from the first peer station (P2P1). The AP may also encode a TB physical layer protocol data unit (PPDU) in accordance with a multi-user orthogonal frequency division multiple access (MU OFDMA) frame format a transmission to the first peer station (P2P1) in accordance with an uplink multi-user multiple-input multiple output (UL MU MIMO) technique.

摘要： Methods, apparatuses, and computer readable media for location measurement reporting in a wireless network are disclosed. An apparatus of a responder station (RSTA) is disclosed, the apparatus comprising processing circuitry configured to decode a null data packet (NDP) announce (NDPA) frame from an initiator station (ISTA), the NDPA frame comprising an indication of a temporary key and an identification of the RSTA. The processing circuitry further configured to decode a NDP from the ISTA, the NDP comprising long training fields (LTFs), the NDP received on a channel. The processing circuitry further configured to determine whether the NDP from the ISTA is consistent with the NDP being generated using a temporary key shared between the ISTA and RSTA based on a comparison of the channel estimates. The processing circuitry may be further configured to determine for authentication whether the indication of the temporary key was generated based on the temporary key.

摘要： Embodiments of an access point (AP), station (STA) and method of sounding are generally described herein. The AP may transmit, during a transmission opportunity (TXOP), a trigger frame (TF) to indicate that an STA is to transmit an uplink sounding packet during an uplink sounding period of the TXOP. The AP may attempt to detect the uplink sounding packet during the uplink sounding period. If the uplink sounding packet is not detected during the uplink sounding period, the AP may transmit a recovery packet to cause other STAs to determine a busy condition during the uplink sounding period. If the uplink sounding packet is detected during the uplink sounding period, the AP may determine a channel estimate for the STA based at least partly on the uplink sounding packet.
