Techniques for improving new radio (NR) positioning performance
Systems, methods, and circuitries are disclosed for determining a position of a wireless device. In one example, an apparatus for a first wireless communication device including baseband circuitry having a radio frequency (RF) interface configured to transmit and receive RF signals is provided. The apparatus includes one or more processors configured to process a signal received from a second wireless communication device to identify at least first arrival path and a different arrival path between the first wireless communication device and the second wireless communication device; and determine a location of the second wireless communication device based on the first arrival path and the different arrival path.
1. An apparatus, comprising:
a memory to store information; and
processing circuitry coupled with the memory, the processing circuitry configured to:
receive a sequence initialization parameter from a base station, wherein the sequence initialization parameter indicates a value used by the base station to initialize a sequence used to generate a positioning signal, wherein the sequence initialization parameter is transmitted in signaling that is specific to a target user equipment (UE); and
receive the positioning signal from the base station based on the sequence initialization parameter.
2. The apparatus of claim 1 , wherein the sequence initialization parameter is only transmitted in signaling that is specific to the target UE.
3. The apparatus of claim 1 , wherein the sequence initialization parameter is unique to the UE.
4. A user equipment (UE) comprising:
a memory; and
a processor configured to, when executing instructions stored in the memory:
receive a sequence initialization parameter from a base station, wherein the sequence initialization parameter indicates a value used by the base station to initialize a sequence used to generate a positioning signal, wherein the sequence initialization parameter is transmitted in signaling that is specific to the UE; and
receive the positioning signal from the base station based on the sequence initialization parameter.
5. The UE of claim 4 , wherein the sequence initialization parameter is only transmitted in signaling that is specific to a target UE.
6. The UE of claim 4 , wherein the sequence initialization parameter is unique to the UE.
7. A method for a user equipment (UE) comprising:
receiving a sequence initialization parameter from a base station in signaling that is specific to the UE, wherein the sequence initialization parameter indicates a value used by the base station to initialize a sequence used to generate a positioning signal; and
receiving the positioning signal from the base station based on the sequence initialization parameter.
8. The method of claim 7 , wherein the-sequence initialization parameter is only transmitted in signaling that is specific to a target UE.
9. The method of claim 7 , wherein the sequence initialization parameter is unique to the UE.
