Abstract
Provided is a method for providing positioning of user equipment (UE). UE receives configuration information for transmission of Sounding Reference Signal (SRS) resources for positioning to be associated with a higher layer parameter, which has a plurality of values respectively corresponding to a plurality of transmit (Tx) timing offsets of the UE. The UE transmits SRS resources for positioning associated with the higher layer parameter according to the configuration information to a plurality of TRPs. The plurality of values of the higher layer parameter are used for calculating positioning measurements between the UE and the plurality of TRPs based on the plurality of Tx timing offsets of the UE, and the calculated positioning measurements are used for determining the position of the UE.

A method for providing positioning of a user equipment (UE), comprising:
- receiving, by the UE, configuration information for transmission of Sounding Reference Signal (SRS) resources for positioning to be associated with a higher layer parameter, wherein the higher layer parameter has a plurality of values respectively corresponding to a plurality of transmit (Tx) timing offsets of the UE;
- and
- transmitting, from the UE, SRS resources for positioning associated with the higher layer parameter according to the configuration information to a plurality of transmission/reception points (TRPs), wherein the plurality of values of the higher layer parameter are used for calculating, by the plurality of TRPs, positioning measurements between the UE and the plurality of TRPs based on the plurality of Tx timing offsets of the UE, and wherein the calculated positioning measurements are used for determining the position of the UE.
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, and configured to:
- receive configuration information for transmission of Sounding Reference Signal (SRS) resources for positioning to be associated with a higher layer parameter, wherein the higher layer parameter has a plurality of values respectively corresponding to a plurality of transmit (Tx) timing offsets of the UE;
- and
- transmit SRS resources for positioning according to the configuration information to a plurality of transmission/reception points (TRPs), wherein the plurality of values of the higher layer parameter are used for calculating, by the plurality of TRPs, positioning measurements between the UE and the plurality of TRPs based on the plurality of Tx timing offsets of the UE, and wherein the calculated positioning measurements are used for determining the position of the UE.
A transmission/reception point (TRP), comprising:
- a memory;
- at least one transceiver;
- and
- at least one processor communicatively coupled to the memory and the at least one transceiver, and configured to:
- receive, from a user equipment (UE), a Sounding Reference Signal (SRS) resource for positioning associated with a higher layer parameter, wherein the higher layer parameter has a value corresponding to a transmit (Tx) timing offset of the UE;
- calculate a positioning measurement between the UE and the TRP based on the SRS resource and according to the Tx timing offset of the UE;
- and
- report the calculated positioning measurement associated with the Tx timing offset to a location server for determining the position of the UE.
