PRS-based terrestrial beacon system (TBS) implementations
First Claim
1. A method to facilitate position determination operations, the method comprising:
- producing, by a location transmission unit (LTU) configured for downlink-only communication, one or more subframes comprising one or more LTU broadcast positioning reference signals, wherein one or more signals transmitted by the LTU are configured to be detected by at least one mobile wireless device based on LTU broadcast control signals, with at least some of the LTU broadcast control signals being configured to be transmitted by a different wireless node than the LTU; and
transmitting, by the LTU, the one or more LTU broadcast positioning reference signals configured for use in determining a position of the at least one mobile wireless device, the one or more LTU broadcast positioning reference signals being configured to be detected by the at least one mobile wireless device.

Abstract
Disclosed are methods, devices, systems, apparatus, servers, computer-/processor-readable media, and other implementations, including an example method to facilitate position determination operations that includes producing, by a location transmission unit (LTU) configured for downlink-only communication, one or more subframes comprising one or more LTU broadcast positioning reference signals. The LTU is detectable by at least one mobile wireless device based on LTU broadcast control signals, with at least some of the LTU broadcast control signals being transmittable by a different wireless node than the LTU. The method also includes transmitting, by the LTU, the one or more LTU broadcast positioning reference signals usable for determination of a position of at least one mobile wireless device, with the one or more LTU broadcast positioning reference signals being detectable by the at least one mobile wireless device.
