摘要： A method is provided. The method includes processing a first request for buffer status received from an access point (AP) and transmitting, during the first uplink multi-user transmission to the AP and in response to the first request for buffer status, a first uplink null data packet including a signal indicating existence of data to be sent from a station (STA) to the AP. The first request for buffer status schedules a first uplink multi-user transmission indicating a plurality of resources indicating existence of data to be sent to the AP. Transmitting the first uplink null data packet includes the STA transmitting the signal on a first resource of the plurality of resources.

摘要： This disclosure describes systems, methods, and devices related to uplink (UL) null data packet (NDP) format for passive location. A device may cause to send a trigger frame that solicits poll response to one or more anchor stations involved in a passive ranging measurement. The device may identify one or more polling response frames received from the one or more anchor stations. The device may cause to send a trigger frame that solicits uplink null data packet (NDP) to the one or more anchor stations, wherein the uplink NDP comprises an indication of a high efficiency (HE) single user (SU) frame type. The device may identify one or more uplink NDPs received from the one or more anchor stations.

摘要： A method and apparatus may be used in wireless communications. The apparatus may be an access point (AP), and may transmit a power save frame. The power save frame may include one or more Uplink (UL) Transmission Times (ULT)s. The apparatus may determine that a station (STA) did not transmit during its respective ULT. The AP may transmit another power save frame. The other power save frame may include a modified ULT. The modified ULT may be for a STA that did not transmit during its respective ULT. The other power save frame may include an unmodified ULT. The unmodified ULT may be for a STA that did not transmit.

摘要： Methods, systems, and devices for wireless communication are described. A first wireless communications device may transmit, to one or more second wireless communications devices, a first message that triggers transmission of a second message by each of the one or more second wireless communications devices, the first message allocating to each of the one or more second wireless communications devices a respective frequency-based resource unit for transmission of the second message, each of the respective frequency-based resource units spanning a portion of a channel bandwidth of a channel. The first wireless communications device may perform channel sensing measurements on the second message received from each of the one or more second wireless communications devices. The first wireless communications device may estimate the channel based on the channel sensing measurements performed on the respective second messages received on the respective frequency-based resource units.
