Methods and systems for enhanced round trip time (RTT) exchange

摘要

Disclosed are systems, methods and devices for obtaining round trip time measurements for use in location based services. In particular implementations, a fine timing measurement request message wirelessly transmitted by a first transceiver device to a second transceiver device may permit additional processing features in computing or applying a signal round trip time measurement. Such a signal round trip time measurement may be used in positioning operations.

主权项

1. A method comprising, at a first wireless transceiver device:
transmitting a fine timing measurement request message to a second wireless transceiver device, the fine timing measurement request message comprising at least one field specifying one or more aspects for transmission of a plurality of fine timing measurement messages in a burst of fine timing measurement messages requested for transmission from the second wireless transceiver in response to receipt of the fine timing measurement request message at the second wireless transceiver device.
