Abstract

Examples of the disclosure relate to sidelink positioning. In examples of the disclosure a UE is configured to determine Discontinuous Reception (DRX) assistance information for sidelink positioning. The DRX assistance information comprises information indicative of a DRX configuration information for one or more target UEs. The UE can then enable transmission of the DRX assistance information to one or more candidate anchor UEs.

Claims (23)

1 . A candidate anchor user equipment (UE) comprising:

at least one processor; and

at least one memory storing instructions which when executed by the at least one processor cause the candidate anchor UE at least to perform:

receiving, from another UE that is participating or has participated in a sidelink positioning session with one or more target UEs, Discontinuous Reception (DRX) assistance information for sidelink positioning, wherein the DRX assistance information comprises information indicative of DRX configuration information for the one or more target UEs.

2 . The candidate anchor UE as claimed in claim 1 , wherein the candidate anchor UE is further caused to perform:

participating, as an anchor UE, in the sidelink positioning session with the one or more target UEs.

3 . The candidate anchor UE as claimed in claim 1 , wherein the candidate anchor UE is further caused to perform:

determining, based on the information indicative of the DRX configuration information, a DRX configuration to be used in the sidelink positioning session with the one or more target UEs.

4 . The candidate anchor UE as claimed in claim 1 , wherein the candidate anchor UE is further caused to perform:

using a DRX configuration indicated in the DRX assistance information to participate, as an anchor UE, in the sidelink positioning session with the one or more target UEs.

5 . The candidate anchor UE as claimed in claim 1 , wherein the candidate anchor UE is further caused to perform:

adapting a current DRX configuration used for the sidelink positioning based on the received DRX assistance information.

6 . The candidate anchor UE as claimed in claim 1 , wherein the information indicative of the DRX configuration information for at least one of the one or more target UEs comprises at least one of:

a type of the at least one of the one or more target UEs;

a DRX configuration used in the sidelink positioning session with the one or more target UEs; or

a class of the DRX configuration of the one or more target UEs.

7 . The candidate anchor UE as claimed in claim 1 , wherein the candidate anchor UE is further caused to perform:

enabling a request for the DRX assistance information to be transmitted from the candidate anchor UE to the another UE.

8 . A target user equipment (UE) comprising:

at least one processor; and

at least one memory storing instructions which when executed by the at least one processor cause the target UE at least to perform:

participating as the target UE in a sidelink positioning session with a first anchor UE using a Discontinuous Reception (DRX) configuration; and

continuing the sidelink positioning session with a second anchor UE using the same DRX configuration.
