Wireless device location services
First Claim
1. A method of operating a location measurement unit (LMU) in an Evolved Universal Terrestrial Radio Access Network (E-UTRAN), the method comprising:
- receiving a reception instruction from a location determining node, the reception instruction comprising information associated with at least one uplink (UL) sounding reference signal (SRS) resource for a user equipment (UE) in the E-UTRAN;
receiving, from the UE, an SRS according to the information associated with at least one UL SRS resource; and
sending, to the location determining node, locating information determined based at least in part on the SRS.

Abstract
A system for determining location information for a wireless device is described. The system includes a UE, a LE and multiple LMUs. The LE sends, to the LMUs, reception instructions with characteristics of the signal transmission from the UE and each LMU receives, from the LE, the reception instructions. The UE sends a signal transmission. Each LMU receives the transmitted signal from the UE, determines locating information based at least in part of the received signal and sends the locating information to the LE. The LE receives the locating information regarding the transmitted signal and determines a location of the UE based at least in part on the received locating information. Methods, apparatus and computer readable media are also described.

9. A computer program product embodied on a non-transitory computer readable medium tangibly encoded with a computer program configured to provide instructions that when executed by at least one processor of a location measurement unit (LMU) in an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) cause the at least one processor to perform actions comprising:
-
receiving a reception instruction from a location determining node, the reception instruction comprising information associated with at least one uplink (UL) sounding reference signal (SRS) resource for a user equipment (UE) in the E-UTRAN; receiving, from the UE, an SRS in the at least one UL SRS resource; determining locating information based at least in part on the SRS; and sending the locating information to the location determining node. - View Dependent Claims (10)
