An apparatus of a HEW master station is disclosed. The HEW master station includes transceiver circuitry and processing circuitry configured to transmit a random access trigger frame (TF-R) to a plurality of HEW stations, and receive resource requests from one or more of the plurality of HEW stations in response to the TF-R. The transceiver circuitry and processing circuitry is further configured to transmit an indication when a trigger frame is to be transmitted. The trigger frame is to comprise resource allocations in response to the resource requests. An apparatus of a HEW station may enter a power save mode until a time when a trigger frame is scheduled that includes resource allocations in response to resource requests transmitted to a master station from the HEW station.

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.

摘要： A first access node of a first network utilizes code sequences, assigned to different user devices, to distinguish at least acknowledgements received in parallel or sequentially from those user devices. The first access node determines from received signaling that a root sequence of the code sequences is in use by a second access node of a second network, then changes that root sequence of the code sequences assigned to the different user devices. In certain examples the access nodes are WLAN access points APs and the acknowledgements are received in response to a group probe/poll. In various embodiments the first AP monitors its neighbors' group probes/polls to learn the root sequences/basic service sets in use in those neighbor networks, or the AP's own stations monitor and send the information in neighbor reports. This latter option can be initiated by the stations themselves, or by the AP.
