Abstract
In an aspect, a UE determines a mapping a mapping between (i) one or more measurements of one or more reference signals based on one or more transmit codebooks and (ii) one or more angles of departure (AoDs) associated with transmission of the one or more reference signals. The UE transmits an indication of the mapping to a position estimation entity. The position estimation entity determines a positioning estimate of the UE based at least in part upon the one or more AoDs.
Claims38
A method of operating a user equipment (UE), comprising:
- receiving configuration of one or more reference signals to be measured;
- receiving configuration of one or more transmit codebooks associated with the reference signals to be measured;
- determining one or more measurements of the one or more reference signals based on the one or more transmit codebooks;
- determining a mapping between (i) the one or more measurements of the one or more reference signals and (ii) one or more angles of departure (AoDs) associated with transmission of the one or more reference signals;
- and
- transmitting an indication of the mapping to a position estimation entity.
A method of operating a position estimation entity, comprising:
- receiving, from a user equipment (UE), an indication of a mapping between (i) one or more measurements of one or more reference signals based on one or more transmit codebooks, and (ii) one or more angles of departure (AoDs) associated with transmission of the one or more reference signals;
- and
- determining a positioning estimate of the UE based at least in part upon the one or more AoDs.
A user equipment (UE), comprising:
- a memory;
- at least one transceiver;
- and
- at least one processor communicatively coupled to the memory and the at least one transceiver, the at least one processor configured to:
- receive configuration of one or more reference signals to be measured;
- receive configuration of one or more transmit codebooks associated with the reference signals to be measured;
- determine one or more measurements of the one or more reference signals based on the one or more transmit codebooks;
- determine a mapping between (i) the one or more measurements of the one or more reference signals and (ii) one or more angles of departure (AoDs) associated with transmission of the one or more reference signals;
- and
- transmit an indication of the mapping to a position estimation entity.
A position estimation entity, comprising:
- a memory;
- at least one transceiver;
- and
- at least one processor communicatively coupled to the memory and the at least one transceiver, the at least one processor configured to:
- receive, from a user equipment (UE), an indication of a mapping between (i) one or more measurements of one or more reference signals based on one or more transmit codebooks, and (ii) one or more angles of departure (AoDs) associated with transmission of the one or more reference signals;
- and
- determine a positioning estimate of the UE based at least in part upon the one or more AoDs.
