Abstract: This disclosure describes systems, methods, and devices related to fine timing measurement (FTM) time synchronization and location estimation. A device may determine a FTM request received from an initiator device, wherein the first FTM request comprises a first trigger field. The device may determine to establish a first FTM session with the initiator device based on the first trigger field. The device may identify a second FTM request received from the initiator device, wherein the second FTM request comprises a second trigger field. The device may determine to establish a second FTM session with the initiator device based on the first trigger field and the second trigger field.

Abstract: In a dense wireless environment with spatial diversity and with multiple access points (APs) and multiple users (STAs), a common network controller may be used to determine which AP-STA combinations can operate simultaneously over the same channel without interfering with other AP-STA combinations. Each STA associates with each AP in a way that derives directionality, signal strength, array weight vectors, etc., for that AP and then provides that information to that AP. Each AP collects similar information from every STA in the network, and forwards the collected information to a Central Controller, who uses the combined information from all APs to determine which AP-STA combinations may operate simultaneously without causing interference with each other.
