Positioning SRS transmissions during a discontinuous reception cycle
A base station of a network acts as a serving node for a user equipment (UE). The UE is a target UE in a positioning method initiated by the network. The base station compares discontinuous reception (DRX) timing information for a DRX cycle of the UE with positioning sounding reference signal (SRS) timing information for an SRS configuration of the UE, determines whether the positioning SRS is located within an inactive time of the DRX cycle and when the positioning SRS is located within the inactive time of the DRX cycle, modifies one of the DRX cycle or the SRS configuration.
1 . A base station of a network acting as a serving node for a user equipment (UE), the UE being a target UE in a positioning method initiated by the network, comprising:
one or more processors configured to:
compare discontinuous reception (DRX) timing information for a DRX cycle of the UE with positioning sounding reference signal (SRS) timing information for an SRS configuration of the UE;
determine whether the positioning SRS is located within an inactive time of the DRX cycle; and
when the positioning SRS is located within the inactive time of the DRX cycle, modifying one of the DRX cycle or the SRS configuration.
2 . The base station of claim 1 , wherein the DRX cycle is modified such that the positioning SRS is located within an active time of the DRX cycle.
3 . The base station of claim 1 , wherein the DRX cycle is modified to a non-DRX.
4 . The base station of claim 1 , wherein the positioning SRS is a periodical positioning SRS or a semi-persistent positioning SRS.
5 . The base station of claim 1 , wherein the SRS configuration is modified such that a reconfigured positioning SRS is located within an active time of the DRX cycle.
6 . The base station of claim 1 , wherein the SRS configuration is modified to an aperiodical positioning SRS.
7 . A method, comprising:
at a base station of a network acting as a serving node for a user equipment (UE), the UE being a target UE in a positioning method initiated by the network:
comparing discontinuous reception (DRX) timing information for a DRX cycle of the UE with positioning sounding reference signal (SRS) timing information for an SRS configuration of the UE;
determining whether the positioning SRS is located within an inactive time of the DRX cycle; and
when the positioning SRS is located within the inactive time of the DRX cycle, modifying one of the DRX cycle or the SRS configuration.
8 . The method of claim 7 , wherein the DRX cycle is modified such that the positioning SRS is located within an active time of the DRX cycle.
9 . The method of claim 7 , wherein the DRX cycle is modified to non-DRX.
10 . The method of claim 7 , wherein the positioning SRS is a periodical positioning SRS or a semi-persistent positioning SRS.
11 . The method of claim 7 , wherein the SRS configuration is modified so that a reconfigured positioning SRS is located within an active time of the DRX cycle.
12 . The method of claim 7 , wherein the SRS configuration is changed to an aperiodical positioning SRS.
13 . A non-transitory computer readable storage medium comprising a set of instructions that when executed by a processor of a base station causes the processor to perform operations, comprising:
compare discontinuous reception (DRX) timing information for a DRX cycle of a user equipment (UE) with positioning sounding reference signal (SRS) timing information for an SRS configuration of the UE;
determine whether the positioning SRS is located within an inactive time of the DRX cycle; and
when the positioning SRS is located within the inactive time of the DRX cycle, modifying one of the DRX cycle or the SRS configuration.
14 . The non-transitory computer readable storage medium of claim 13 , wherein the DRX cycle is modified such that the positioning SRS is located within an active time of the DRX cycle.
15 . The non-transitory computer readable storage medium of claim 13 , wherein the DRX cycle is modified to a non-DRX.
16 . The non-transitory computer readable storage medium of claim 13 , wherein the positioning SRS is a periodical positioning SRS or a semi-persistent positioning SRS.
17 . The non-transitory computer readable storage medium of claim 13 , wherein the SRS configuration is modified such that a reconfigured positioning SRS is located within an active time of the DRX cycle.
18 . The non-transitory computer readable storage medium of claim 13 , wherein the SRS configuration is modified to an aperiodical positioning SRS.
