Description

Information processing method, device and readable storage medium

Technical Field

The present application relates to the field of communications technologies, and in particular, to an information processing method, an information processing device, and a readable storage medium.

Background

When the measurement of the positioning reference signal is performed, the terminal needs to be in an awake state to monitor the downlink signal, but this may result in relatively large power consumption of the terminal. Furthermore, for terminals configured with WUS (wake-up), or DCP (DCI with CRC scrambled by PS-RNTI, DCI using PS-RNTI scrambling CRC), or PEI (Paging Early Indication, paging indication), it will only continue to monitor paging at the next corresponding paging occasion, or PDCCH (Physical downlink control channel ) at the next corresponding (e) DRX (Discontinuous Reception ) on occasion when WUS, or DCP, or PEI is detected in order to reduce power consumption.

When positioning is performed on a terminal configured with a WUS/DCP/PEI mechanism, the current LMF is likely to cause power consumption waste when the terminal performs positioning measurement in a positioning reference signal configuration mode.

By using the scheme of the embodiment of the application, the configuration of the positioning reference signal and the WUS, DCP or PEI configuration of the terminal can be coordinated through the energy-saving auxiliary information, so that the terminal can measure the downlink positioning reference signal while detecting the WUS, the DCP or PEI, thereby reducing the power consumption of positioning measurement.

Referring to fig. 3, fig. 3 is a flowchart of an information processing method according to an embodiment of the present application, as shown in fig. 3, including the steps of:

step 301, the second RAN node receives a second message sent by the LMF, where the second message is used to indicate energy saving auxiliary information.

Wherein the energy saving auxiliary information includes at least one of:

Optionally, the second RAN node receives PRS configuration information sent by the LMF. For example, the second RAN node may receive PRS configuration information sent by the LMF via, but not limited to, an NRPPa message, for which other messages, signaling, may be used later for communication between the LMF and the RAN node.

Wherein the PRS configuration information includes at least one of:

Positioning the offset of the reference signal in each period;

The second message may be, for example, a second NRPPa message. The content and the specific meaning of the second message may refer to the description of the foregoing embodiment, and are not repeated herein.

In the prior art, when positioning is performed on a terminal configured with a WUS/DCP/PEI mechanism, the current LMF does not coordinate with the WUS/DCP/PEI configuration of the terminal when positioning reference signals are configured, which may cause waste of power consumption when the terminal performs positioning measurement.

To solve the above-described problem, in one embodiment of the present application, the LMF acquires a corresponding WUS, or DCP, or PEI configuration from an NG-RAN (next generation RAN node) node, and further can perform PRS configuration based on the information. In this embodiment, taking LMF to obtain WUS configuration as an example, the interactive flow steps for LMF to obtain other configuration information are similar.

It is assumed that the LMF has previously acquired (e) DRX configuration information, and/or paging configuration information, for the corresponding located UE.

This embodiment may include:

in step 11, optionally, after the positioning service arrives, the LMF sends a third message to the NG-RAN to request to obtain WUS configuration information of the located UE.

Specifically, in this step, the LMF may send an NRPPa request message to the NG-RAN to request to obtain WUS configuration information of the located UE, where the NRPPa request message carries at least one of the following:

identification information of the located UE;

service base station identification information;

LMF identification information;

and requesting to acquire the indication information of the WUS configuration information of the UE.

Step 12, the NG-RAN sends a first message to the LMF, and feeds back WUS configuration information configured for the located UE to the LMF through the first message.

Specifically, in this step, the NG-RAN sends an NRPPa message to the LMF, where the NRPPa message carries at least one of the following;

identification information of the located UE;

service base station identification information;

LMF identification information;

WUS configuration information for the UE;

UE ID of UE;

paging probability threshold value of UE.

In step 13a, optionally, after determining WUS configuration information of the located UE, the LMF calculates a time domain location of the corresponding WUS based on the WUS configuration information of the UE, the paging configuration information, DRX information, etc., which have been determined previously, and configures a positioning reference signal based thereon. Specific:

The LMF determines positioning reference signal configuration information and transmits the recommended positioning reference signal configuration information to a current service base station and/or a neighboring base station through NRPPa information, wherein the recommended positioning reference signal configuration information comprises at least one of the following items:

positioning a reference signal period;

an offset of the positioning reference signal in each period;

In step 13b, optionally, after determining WUS configuration information of the located UE, the LMF sends a second message (e.g., NRPPa message) to the neighboring base station, so as to transfer the WUS configuration information of the located UE to the neighboring base station.

In particular applications, step 13a and step 13b may be implemented as two parallel schemes.

Step 14, based on step 13b, the current serving base station and/or the neighboring base station configures the downlink positioning reference signal according to WUS configuration information of the located UE, so that a time domain transmission position of the downlink positioning reference signal falls within a detection window of the WUS signal.

In one embodiment of the application, the LMF obtains the WUS, or DCP, or PEI time domain location information directly from the NG-RAN, and further can perform PRS configuration based on such information. In this embodiment, the base station directly provides the corresponding WUS, or DCP, or PEI time domain transmit location information to the LMF, and the LMF may directly determine how to configure according to the time domain location information, without calculating the corresponding WUS, DCP, or PEI time domain location information according to the configuration information of the WUS, or DCP, or PEI, etc.

Taking LMF to obtain WUS configuration as an example, the interactive flow steps of LMF to obtain other configuration information are similar. It is assumed that the LMF has previously acquired (e) DRX configuration information, and/or paging configuration information, for the corresponding located UE. This embodiment may include:

in step 21, optionally, after the positioning service arrives, the LMF sends a third message to the NG-RAN to request to obtain WUS configuration information of the located UE.

Specifically, the LMF may send an NRPPa request message to the NG-RAN, where the NRPPa request message carries at least one of the following:

identification information of the located UE;

service base station identification information;

LMF identification information;

requesting to acquire indication information of the WUS time domain position of the UE;

step 22, the NG-RAN sends a first message to the LMF, and feeds back WUS configuration information configured for the positioning UE to the LMF through the first message.

Specifically, the NG-RAN sends an NRPPa message to the LMF, where the NRPPa message carries at least one of the following items;

identification information of the located UE;

service base station identification information;

LMF identification information;

WUS time domain location information of the UE;

in step 23a, optionally, after the LMF determines WUS configuration information of the located UE, the location reference signal is configured based on WUS time domain location information of the UE. Specifically, namely:

positioning a reference signal period;

an offset of the positioning reference signal in each period;

locating the time domain transmission position of the reference signal in each period;

in step 23b, optionally, after determining WUS time domain location information of the located UE, the LMF sends a second message (e.g., NRPPa message) to the neighboring base station, so as to transfer the WUS time domain location information of the located UE to the neighboring base station.

In particular applications, step 23a and step 23b may be implemented as two parallel schemes.

Step 24, based on step 23b, the current serving base station and/or the neighboring base station configures the downlink positioning reference signal according to WUS time domain position information of the located UE, so that a time domain transmission position of the downlink positioning reference signal falls within a detection window of the WUS signal.

As can be seen from the above description, in the embodiment of the present application, the configuration of the positioning reference signal and the WUS, or DCP, or PEI configuration of the terminal may be coordinated, so as to ensure that the time domain transmission position of the positioning reference signal is located on the detection occasion of the corresponding WUS, or DCP, or PEI, so that the terminal performs measurement of the downlink positioning reference signal while detecting the WUS, or DCP, or PEI, thereby reducing the power consumption of positioning measurement.
