CPC G01S 5/0273 (2013.01) [G01S 5/02 (2013.01); G01S 5/0268 (2013.01)] | 17 Claims |
1. An apparatus comprising:
a memory to store configuration information that a user equipment (UE) is to use to perform a multi-path channel component measurement; and
processing circuitry, coupled with the memory, the processing circuitry configured to:
retrieve the configuration information from the memory;
generate a message that comprises the configuration information;
encode the message for transmission to the UE;
receive, from the UE, the multi-path channel component measurement, wherein:
the multi-path channel component measurement comprises a first signal location parameter (SLP) for a first signal received directly by the UE from the apparatus and a second SLP for a second signal received by the UE from the apparatus after being reflected from an object,
the first SLP comprises at least one of a first time of arrival (TOA) parameter, a first time difference of arrival (TDOA) parameter, a first propagation time, a first angle of arrival, a first angle of departure, or a first reference signal power level associated with the first signal, and
the second SLP comprises at least one of a second TOA parameter, a second TDOA parameter, a second propagation time, a second angle of arrival, a second angle of departure, or a second reference signal power level associated with the second signal;
determine a position of a virtual reference source based on the multi-path channel component measurement, wherein the determining the position of the virtual reference source comprises determining an absolute coordinate of the virtual reference based on a position of the apparatus and a reflection surface geometry of the object; and
determine a position of the UE based on the position of the virtual reference source.
