The following first describes what the scheme provided in the embodiments of the present application relates to.

1. DRX or eDRX

DRX or eDRX (extended discontinuous reception) techniques are introduced for terminal power saving. The core idea is that the UE periodically enters a sleep state (sleep mode) at certain time, does not monitor a PDCCH subframe (connection state) or does not monitor paging, and wakes up (wake up) from the sleep state when monitoring is needed, so that the UE can achieve the purpose of saving electricity.

The network side configures corresponding (e) DRX configuration for the terminal, wherein the configuration comprises the following steps: DRX or eDRX cycle, on-duration timer, paging listening window (only for eDRX), etc.

The DRX or eDRX cycle in IDLE/INACTIVE state is usually configured by the core network and the base station together, that is, the core network side configures a paging DRX cycle specific to the UE, the base station side configures a default paging DRX cycle by broadcasting, and/or the base station side additionally configures a paging DRX cycle specific to the UE. The UE side selects the DRX cycle having the shortest cycle from the DRX cycles configured at the network side as its final application.

2. Downlink positioning process

The downlink positioning process mainly comprises the following steps:

The method comprises the steps that 1, DL-PRS information configured by a base station is obtained between an LMF and the base station through a TRP (Transmit-Receive Point) Information Request/Response (request message or Response message) process;

flow 2. Information related to the UE positioning capability is interacted between the UE and the LMF;

after obtaining the positioning capability of the UE, the LMF determines that a downlink positioning method (DL-AOD/DL-TDOA) related to the RAT is required to be adopted, selects corresponding DL-PRS configuration for the UE as auxiliary data, and issues the auxiliary data to the UE;

the LMF issues a long term evolution positioning protocol LPP (LTE Positioning Protocol) Request Location Information (request position information) message to request the UE to report the positioning measurement result and/or the position estimation result;

after receiving the message, triggering the UE to perform corresponding downlink DL-PRS measurement based on the DL-PRS configuration in the received auxiliary data, and/or performing position estimation according to the measurement result;

flow 6.Ue reports its DL-PRS measurements and/or position estimates to LMF via LPP Provide Location Information message.

Flow 7. LMF then performs location estimation (for UE-assisted positioning) based on its DL-PRS measurements and feeds back the estimated location to the initiating positioning requester.

Further, taking downlink positioning as an example, the downlink positioning reference signal (DL-PRS) is statically configured by OMA, and when the DL-PRS is configured, DRX or eDRX configuration applied by the terminal cannot be known, which may cause that the network side cannot configure the positioning reference signal based on the DRX configuration of the UE, so that positioning measurement efficiency is low, precision is poor, and even positioning fails. For example, the positioning reference signal configured by the network always fails to fall into the DRX on of the terminal, which results in too long time for the terminal to perform positioning measurement, and even positioning failure. Similar problems exist in the uplink positioning scenario.

Specifically, the embodiment of the invention provides a configuration method, a device, an LMF, a base station, an AMF and a terminal for positioning reference signals, which are used for solving the problem that in the prior art, the positioning reference signals can not fall in the DRX duration of the terminal all the time, so that the terminal can not correctly receive the positioning reference signals.

For example, for an uplink positioning scenario, the LMF determining an uplink positioning reference signal (UpLink Sounding Reference Symbol, UL-SRS) configuration of the terminal according to the determined (e) DRX configuration may include: the LMF determines corresponding SRS configuration parameters according to the (e) DRX configuration, and specifically configures: a relation between the SRS period and (e) DRX period of the UE being an integer multiple; the transmission time when the SRS exists in each period falls within the on-duration window of the UE.

In an embodiment, before step 101, the method further comprises:

and acquiring configuration information of DRX or eDRX of the terminal.

In the step, the DRX or eDRX configuration information of the terminal is obtained, and the DRX or eDRX or DRX configuration of the shortest DRX or eDRX period is used as the DRX or eDRX configuration applied by the UE side.
