摘要： This disclosure describes systems, methods, and devices related to multi-AP resource sharing. A device may participate in a set of coordinated access points (APs) for coordinating a sharing of one or more resources. The device may evaluate whether there is data to be transmitted to at least one associated station device. The device may, based on the evaluation, perform an action associated with acquiring a first transmit opportunity (TXOP) to be shared with one or more candidate APs of the set of coordinated APs.

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： To communicate with a plurality of non-AP stations (STAs) within synchronized transmission opportunities (S-TXOPs), an access point station (AP) performs an initial management frame exchange with the STAs. During the initial management frame exchange, one or more sets of semi-static allocation parameters are signalling to the STAs. Each set of semi-static allocation parameters is associated with an allocation index (IDx). The AP may communicate data with the STAs during S-TXOPs that follow the initial management frame exchange. Each of the S-TXOPs may include an S-TXOP trigger. The S-TXOP trigger may be encoded to include one of the allocation indices to indicate a known allocation for use during the associated S-TXOP when a set of the predetermined semi-static allocation parameters are to be used. The S-TXOP trigger may be encoded to include full allocation information to indicate a new allocation for use during the associated S-TXOP when the predetermined semi-static allocation parameters are not used.

摘要： An access point (AP) station (STA) configured for communicating with another STA within a synchronized transmission opportunity (S-TXOP) may encode an S-TXOP trigger for transmission at a beginning of the S-TXOP. The S-TXOP trigger may be followed by a plurality of slots within the S-TXOP. The S-TXOP trigger may include a synchronization information field, a station information list field and an optional schedule information field. The STA information list field may include an AID of each STA that is scheduled to communicate during the slots and an indication of whether semi-static configuration is enabled. When the S-TXOP trigger includes the optional schedule information field, it may include resource information for each slot which may include a slot identifier and a slot type indicator. The resource allocation for each slot further includes a scheduling information element when the semi-static configuration for the corresponding slot is not enabled.

摘要： Methods, apparatuses, and computer readable media for report identification and power control for ranging in a wireless network are disclosed. An apparatus of a responding station (RSTA) is disclosed, where the apparatus comprises processing circuitry configured to perform ranging with a initiating stations (ISTAs) and maintain a separate sounding dialogue token for each of the ISTAs and transmit a corresponding sounding dialogue token for a ISTA in a trigger frame for ranging and sounding or a null data packet announcement (NDPA) frame, and in a responding to initiating location measurement report. Apparatuses of RSTAs and ISTAS are disclosed that perform power control management during non-trigger-based ranging.

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： This disclosure describes systems, methods, and devices related to efficient poll response frame in wireless communications. A device may cause to send a multiuser location trigger frame of subtype poll to one or more initiating station devices (ISTAs) in a multi-user trigger-based range measurement during a polling phase. The device may identify a first clear to send (CTS) frame received from a first ISTA of the one or more ISTAs during the polling phase. The device may identify a second CTS frame received from a second ISTA of the one or more ISTAs during the polling phase. The device may determine the identity of a first ISTA based on information comprised in the first CTS frame received from the first ISTA. The device may determine the identity of the second ISTA based on information comprised in the second CTS frame received from the second ISTA.
