Abstract

Embodiments of the present disclosure relate to updating positioning assistance configuration. A first device transmits a first request for updating a current positioning assistance configuration of the first device to a second device. The first device is in a radio resource control inactive mode, and the current positioning assistance configuration is used by the first device to receive a plurality of positioning reference signals from a plurality of positioning devices. Further, the first device receives a first response comprising a requested positioning assistance data for updating the current positioning assistance configuration from the second device. In this way, the first device can maintain being in a power saving mode meanwhile update the positioning assistance configuration in time.

First claim

What is claimed is:

1 . A first device comprising:
at least one processor; and at least one memory including computer program code; wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the first device to: transmit, to a second device, a first request for updating a current positioning assistance configuration of the first device, the first device being in a radio resource control inactive mode, the first request is a long term evolution positioning protocol message for updating the current positioning assistance configuration, and the current positioning assistance configuration being used by the first device to receive a plurality of positioning reference signals from a plurality of positioning devices; and receive, from the second device, a first response comprising a requested positioning assistance data for updating the current positioning assistance configuration.

2 . The first device of claim 1 , wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the first device to transmit the first request by:
determining whether at least one of the following conditions is met: a signal strength value of at least one of the plurality of positioning reference signals is below a threshold value, failure to receive at least one of the plurality of positioning reference signals, missing of a Quasi co-location information, outdating of an expected RSTD reference signal time difference; and detection of a further positioning device different from the plurality of positioning devices according to the current positioning assistance configuration of the first device; and in accordance with a determination that at least one of the conditions is met, transmitting the first request to the second device.

3 . The first device of claim 2 , wherein the first request comprises an indication that the at least one of the conditions is met.

4 . The first device of claim 1 ,
wherein the first device is served by the second device and is in the radio resource control inactive mode with respect to the second device; and wherein the first request is a Message 3 of a 4-step random access procedure and the first response is a Message 4 of the 4-step random access procedure.

5 . The first device of claim 4 , wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the first device to transmit the first request by:
transmitting, to the second device, a Message 1 of the 4-step random access procedure transmitted with a pre-configured resource, the pre-configured resource indicating that the Message 3 of the 4-step random access procedure will be used as the first request for updating the current positioning assistance configuration; receiving, from the second device, a Message 2 of the 4-step random access procedure; and transmitting, to the second device, the Message 3 of the 4-step random-access procedure to update the current positioning assistance configuration of the first device.

6 . The first device of claim 1 ,
wherein the first device is served by the second device and is in the radio resource control inactive mode with respect to the second device; and wherein the first request is a Message A of a 2-step random access procedure and the first response is a Message B of the 2-step random access procedure.

7 . The first device of claim 1 , wherein the first device is served by the second device and a fourth device, and is in the radio resource control inactive mode with respect to the fourth device.

8 . The first device of claim 1 , wherein
the first device is a terminal device, and the second device is a network device or a location server.

9 . A second device comprising:
at least one processor; and at least one memory including computer program code; wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the second device to: receive, from a first device, a first request for updating the current positioning assistance configuration of the first device, the first device being in a radio resource control inactive mode, the first request is a long term evolution positioning protocol message for updating the current positioning assistance configuration, and the current positioning assistance configuration being used by the first device to receive a plurality of positioning reference signals from a plurality of positioning devices; and transmit, to the first device, a first response comprising a requested positioning assistance data for updating the current positioning assistance configuration.

10 . The second device of claim 9 , wherein the first request comprises an indication that the at least one of followings conditions is met:
a signal strength value of at least one of the plurality of positioning reference signals is below a threshold value, failure to receive at least one of the plurality of positioning reference signals, missing of a Quasi co-location information, outdating of an expected RSTD reference signal time difference and detection of a further positioning device different from the plurality of positioning devices according to the current positioning assistance configuration of the first device.

11 . The second device of claim 9 ,
wherein the first device is served by the second device and is in the radio resource control inactive mode with respect to the second device; and wherein the first request is a Message 3 of a 4-step random access procedure and the first response is a Message 4 of the 4-step random access procedure.

12 . The second device of claim 11 , wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the second device to receive the first request by:
receiving, from the first device, a Message 1 of the 4-step random access procedure transmitted with a pre-configured resource, the pre-configured resource indicating that the Message 3 of the 4-step random access procedure will be used as the first request for updating the positioning assistance configuration; transmitting, to the first device, a Message 2 of the 4-step random access procedure from the second device; and receiving, from the first device, the Message 3 of the 4-step random-access procedure for updating the current positioning assistance configuration of the first device.

13 . The second device of claim 9 ,
wherein the first device is served by the second device and is in the radio resource control inactive mode with respect to the second device; and wherein the first request is a Message A of a 2-step random access procedure and the first response is a Message B of the 2-step random access procedure.

14 . The second device of claim 9 , wherein the first device is served by the second device and a fourth device, and is in the radio resource control inactive mode with respect to the fourth device.

15 . The second device of claim 9 , wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the second device to transmit the first response by:
transmitting, to a third device, a second request for updating the current positioning assistance configuration of the first device according to the first request; and in accordance with a determination of receiving a second response comprising the requested positioning assistance data from the third device, transmitting, to the first device, the f
