摘要： This disclosure provides systems, methods and apparatus for establishing and maintaining network connections based on ranging information. In one aspect, a wireless device is configured to identify one or more candidate access points (APs) within a vicinity of the wireless device, and exchange fine timing measurement (FTM) frames with candidate APs to determine respective distances between the wireless device and each of the candidate APs. In some aspects, the exchange of FTM frames may be performed when the wireless device is not associated with any AP. In some other aspects, the exchange of FTM frames may be performed when the wireless device is already associated with an existing AP, for example, to determine whether a roaming condition is satisfied. The wireless device then selects one of the candidate APs, based at least in part on the FTM frames, and associates with the selected candidate AP.

摘要： Disclosed are methods, systems and devices for obtaining a range between devices based, at least in part, on an exchange of wireless messages. For example, wireless devices may obtain measurements of range based, at least in part, on an exchange fine timing measurement (FTM) messages during sessions. In one implementation, an initiating wireless station may transmit an initial FTM request message to a responding wireless station wherein the initial FTM request message comprising one or more fields indicating a capability of the initiating STA to generate Range Reports.

摘要： Aspects of the present disclosure may compensate for a presence of phase ambiguity between transmit chains of a transmitting device when estimating angle of departure information of a wireless signal transmitted from the transmitting device. In some aspects, a receiving device may determine phase information of the wireless signal, and then determine whether there is a presence or absence of phase ambiguity between a number of transmit chains of the transmitting device. If there is presence of phase ambiguity in the transmitting device, then the receiving device may adjust the phase information of the received wireless signal. If there is an absence of phase ambiguity in the transmitting device, then the receiving device may not adjust the phase information. Thereafter, the receiving device may estimate the angle of departure of the wireless signal based on the selectively adjusted phase information.

摘要： A system and method are disclosed for performing ranging operations between two wireless devices without employing cyclic shift diversity (CSD) compensation techniques. For some embodiments, a first wireless device sends a negotiation request frame requesting the second wireless device to respond to subsequently received frames of a specified type using a selected one of the transmit chains in the second wireless device. Thereafter, the first wireless device sends a data frame to the second wireless device to initiate a ranging operation. The second wireless device sends a response frame of the specified type to the first wireless device using the selected one of the transmit chains.
