Patent ID: 11696122

Abstract:
Uplink high efficiency location of a user equipment (UE) includes initiating periodic or triggered location in the UE by a location server (LS) in a wireless network. The UE enters an idle state and monitors for triggering events. After detecting an event, the UE transmits an uplink positioning signal (UPS) to a base station, where the UPS encodes UPS data comprising a UE ID, an ID for the LS, an authentication code (AC) and location measurements. UPS transmission occurs in an uplink positioning occasion shared with other UEs. The location measurements may be ciphered but other UPS data is unciphered. The base station obtains additional location measurements and transfers the UPS data and the location measurements to the LS. The LS authenticates the UE ID using the AC, determines the UE location using the location measurements and transfers the location to an external client.
