FIG. 1 shows a block diagram of a communication system provided by an exemplary embodiment of the present disclosure. The communication system may include: an access network 12 , a user terminal 14 and a core network device 16 .

The access network 12 includes several access network devices 120 .

The base station may include various forms of macro base stations, micro base stations, relay stations, access points and so on. In systems using different wireless access technologies, the names of devices with base station functions may be different, for example, in Long Term Evolution (LTE) systems, it is called eNodeB or eNB; in 5G NR (New Radio, new air interface) system, called gNodeB or gNB. As communications technology evolves, the description "base station" may change. In the positioning system, a Transmission Reception Point (TRP) is also introduced. Each access network device can contain at least one TRP. Multiple TRPs send positioning reference signals. The terminal measures the positioning reference signals sent by multiple TRPs and reports the measurement results. Some of these TRPs belong to the access network devices of the serving cell of the terminal. Some are sent by the access network equipment belonging to the adjacent cell (that is, the non-serving cell) of the terminal. For the convenience of description in the embodiments of the present disclosure, the above-mentioned devices that provide the wireless communication function for the user terminal 14 are collectively referred to as network devices.

User terminal 14 may include various handheld devices with wireless communication functions, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to wireless modems, as well as various forms of user equipment, mobile stations (Mobile Station, MS) , terminal device (terminal device) and so on.

The access network device 120 and the user terminal 14 communicate with each other through a certain air interface technology, such as a Uu interface.

The core network device 16 includes a network element with a location management function. Optionally, the location management function network element includes a location server (location server), and the location server can be implemented as any of the following: LMF (Location Management Function, location management network element), E-SMLC (Enhanced Serving Mobile Location Centre, enhanced Service mobile location center), SUPL (Secure User Plane Location, secure user plane location), SUPL SLP (SUPL Location Platform, secure user plane location location platform). The terminal device and the location server use LPP (LTE Positioning Protocol, LTE Positioning Protocol) for communication transmission.

The technical solutions of the embodiments of the present disclosure can be applied to various communication systems, such as: Global System of Mobile Communication (GSM) system, Code Division Multiple Access (CDMA) system, broadband code division multiple access (Wideband Code Division Multiple Access, WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (Time Division Duplex, TDD) system, Advanced long Term Evolution (LTE-A) system, New Radio (NR) system, evolution system of NR system, LTE on unlicensed frequency band (LTE-based access to Unlicensed spectrum, LTE-U) system, NR-U system, Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication system, Wireless Local Area Networks (Wireless Local Area Networks, WLAN), Wireless Fidelity (Wireless Fidelity, WiFi), next-generation communication systems or other communication systems, etc.

FIG. 2 shows a method flow chart of a signal measurement method provided by an exemplary embodiment of the present disclosure. The method is applied to the terminal of the communication system shown in FIG. 1, and the method includes:

Step 210, in the case of the RRC inactive state, determine whether to measure the positioning reference signal according to the first time domain position of the downlink information and the second time domain position of the positioning reference signal.

Downlink information refers to information sent by an access network device, and the downlink information includes downlink channels and/or signals.

Exemplarily, the downlink channel and/or signal includes at least one of the following:

Physical downlink control channel (PDCCH);

Physical downlink shared channel (physical downlink shared channel, PDSCH);

Synchronization Signal/PBCH Block (SSB), including Primary Synchronization Signal (PSS), Secondary Synchronization Signal (SSS), Physical Broadcast Channel (Physical Broadcast Channel, PBCH) and PBCH Demodulation Reference Signal (DMRS);

System Information Block 1 (System Information Block 1, SIB1);

Control resource set 0 (COntrol REsource SET 0, CORESET0);

Message 2 (Message 2, Msg2), that is, the random access response (random access response) of step 2 in the 4-step random access process;

Message B (Message B, MsgB), that is, the random access response of step 2 in the 2-step random access process;

paging;

Downlink Small Data Transmission (DownLink Small Data Transmission, DL SDT).

Exemplarily, when the terminal is in the RRC inactive state, the downlink information is sent by the access network device on the initial downlink bandwidth part (initial Downlink BandWidth Part, initial DL BWP) of the terminal.

Exemplarily, when the terminal is in the RRC inactive state, it acquires the first time domain position of the downlink information and the second time domain position of the positioning reference signal. The time domain resource occupied by the network device when sending downlink information to the terminal. The above-mentioned second time domain position refers to the time domain resource occupied by the access network device when sending PRS to the terminal in the downlink scenario; and the second time domain position, determine whether the time domain resources occupied by the downlink information and the positioning reference signal overlap partially or completely, that is, determine whether there is a reception conflict between the downlink information and the positioning reference signal, and then based on the downlink information and the positioning reference signal Whether there is reception conflict between the signals, determine whether to measure the positioning reference signal. The above reception conflict means that there is a partial or complete overlap between the time domain resources required for receiving downlink information and the time domain resources required for receiving PRS, or the time interval is smaller than the time interval threshold (that is, the time interval is small).

Exemplarily, the first time domain location and/or the second time domain location is configured for the terminal by the access network device; or configured for the terminal by the location server.

Exemplarily, the above-mentioned first time domain position and the second time domain position may be time domain positions on the same frequency domain; or time domain positions on different frequency domains, such as on different bandwidth parts (Bandwidth Part, BWP) time domain position.

Exemplarily, based on the first time domain position and the second time domain position, the terminal determines that there is partial overlap or complete overlap between the time domain resources occupied by the downlink information and the positioning reference signal, or the time interval is less than the time interval threshold, or That is, if it is determined that there is a reception conflict between the downlink information and the positioning reference signal, the positioning reference signal is not measured; based on the first time domain position and the second time domain position, it is determined that the time domain resources occupied by the downlink information and the positioning reference signal do not overlap , or the time interval is greater than or equal to the time interval threshold, that is, it is determined that there is no reception conflict between the downlink information and the positioning reference signal, then measure the positioning reference signal.

To sum up, in the signal measurement method provided by this embodiment, when the terminal is in the RRC inactive state, the terminal can determine the downlink information based on the first time domain position of the downlink information and the second time domain position of the positioning reference signal Whether there is a reception conflict with the positioning reference signal provides a criterion for determining whether to measure or not to measure the positioning reference signal, that is, whether to measure the positioning reference signal.

The above positioning reference signal can be located on the initial downlink bandwidth part, that is, on the same DLBWP as the downlink information; the positioning reference signal can also be located on other downlink bandwidth parts except the initial downlink bandwidth part. For the above two different scenarios, the terminal The manner of determining whether to measure a positioning reference signal is different.

In some embodiments, when the positioning reference signal is located on the initial downlink bandwidth part, the terminal uses the first decision criterion to determine whether to measure the positioning reference signal, as shown in Figure 3, step 210 may include step 310, as shown below:

Step 310, in the case of the RRC inactive state, determine whether to measure the positioning reference signal based on whether the first time domain position and the second time domain position meet the first criterion.

Wherein, the first criterion includes at least one of criterion type 1 and criterion type 2:

Judgment criterion type 1 includes: there is overlap between the first symbol in the first time domain position and the second symbol in the second time domain position;

Judgment criterion type 2 includes: the second symbol in the second time domain position is within the first time window, and the first time window refers to the time window corresponding to the first time domain position.

The above first time window is the time window corresponding to the first time domain position in the case that the positioning reference signal is located on the initial downlink bandwidth part. Optionally, the first time window includes symbols at the first time domain position, X1 symbols before the first time domain position, and Y1 symbols after the first time domain position, where X1 and Y1 are non-negative integers.

Exemplarily, as shown in FIG. 4 , a time slot 0 includes 14 symbols 0-13. Assuming that the first time domain position of the downlink information is symbols 4-8 on slot 0, X1 takes a value of 2, and Y1 takes a value of 1, and the terminal determines that the first time window is symbols 2-9 on slot 0.

Optionally, the X1 symbols and the Y1 symbols are determined based on the subcarrier spacing of the initial downlink bandwidth part. Exemplarily, after the terminal determines to adopt decision criterion type 2, or after starting the positioning function, or after the device itself is started, it obtains the subcarrier spacing of the initial downlink bandwidth part, and determines based on the subcarrier spacing of the initial downlink bandwidth part The symbol length of each of X1 symbols and Y1 symbols and/or X1 symbols and Y1 symbols. For example, there is a corresponding relationship between the subcarrier spacing of the initial downlink bandwidth part and X1 and Y1, and X1 and Y1 corresponding to the subcarrier spacing of the initial downlink bandwidth part are determined based on the above corresponding relationship.

After determining the values of X1 and Y1, the terminal reports its capabilities to the access network device and/or the location server. For example, the terminal can report X1 and Y1 to the access network device and/or the location server; for another example, the terminal can also Reporting to the access network device and/or the location server that at least one of the decision criterion type 1 and the decision criterion type 2 is supported. In this way, the access network device and/or the location server can clearly know the PRS received by the terminal.

After that, the terminal performs step 320 to step 330 according to the judgment result, as follows:

Step 320, if the first time domain position and the second time domain position meet the first criterion, determine not to measure the positioning reference signal.

Exemplarily, if there is partial or complete overlap between the first symbol in the first time domain position and the second symbol in the second time domain position, the terminal determines not to measure the positioning reference signal. For example, in FIG. 5, the first time domain position includes symbols 0-6 on time slot 1, the second time domain position includes symbols 4-8 on time slot 1, and the first time domain position and the symbols in the second time domain position If symbols 4 to 6 overlap, it is determined that the first time domain position and the second time domain position conform to the judgment criterion type 1, and the terminal does not measure the positioning reference signal.

Or, if the second symbol in the second time domain position is within the first time window, the terminal determines not to measure the positioning reference signal. That is, if some or all symbols in the second time domain position are within the first time window, the terminal determines not to measure the positioning reference signal. For example, in Figure 6, the first time domain position includes symbols 4 to 8 on time slot 2, and the second time domain position includes symbols 0 to 3 on time slot 2; when the values of X1 and Y1 are both 1 , the first time window is symbols 3 to 9, therefore, symbol 3 in the second time domain position is within the first time window, the terminal determines that the first time domain position and the second time domain position meet the criterion type 2, and the terminal Positioning reference signals are not measured.

Optionally, the terminal determines not to measure the positioning reference signal when the first time domain position and the second time domain position meet the determination criterion type 1 and the determination criterion type 2. Alternatively, the terminal determines not to measure the positioning reference signal when the first time domain position and the second time domain position conform to the determination criterion type 1 or the determination criterion type 2.

Step 330: Determine the measurement positioning reference signal if the first time domain position and the second time domain position do not meet the first criterion.

Exemplarily, if there is no overlap between the first symbol in the first time domain position and the second symbol in the second time domain position, the terminal determines to measure the positioning reference signal. For example, in FIG. 7, the first time domain position includes symbols 1-3 on time slot 3, the second time domain position includes symbols 5-8 on time slot 3, and the first time domain position and the symbols in the second time domain position If the symbols do not overlap, it is determined that the first time domain position and the second time domain position are not symbol determination criterion type 1, and the terminal measures the positioning reference signal.

Or, if the second symbol in the second time domain position is outside the first time window, the terminal determines to measure the positioning reference signal. That is, if all the symbols in the second time domain position are outside the first time window, the terminal determines to measure the positioning reference signal. For example, in Figure 8, the first time domain position includes symbols 5-8 on time slot 4, and the second time domain position includes symbols 1-2 on time slot 4; when the values of X1 and Y1 are both 2 , the first time window is symbols 3 to 10, therefore, symbols 1 to 2 in the second time domain position are outside the first time window, and the terminal determines that the first time domain position and the second time domain position do not meet the criterion type 2. The terminal measures the positioning reference signal.

Optionally, the terminal determines to measure the positioning reference signal when the first time-domain position and the second time-domain position do not meet the determination criterion type 1 and/or the determination criterion type 2.

It should be noted that the above X1 and Y1 may be used to indicate the time interval threshold. For example, X1 may be used to indicate the time interval threshold between the second time domain position and the initial position of the first time domain position, and Y1 may be used to indicate the time interval between the second time domain position and the end position of the first time domain position. Time interval threshold. If the end position of the second time domain position is before the initial position of the first time domain position and the time interval between the initial position of the first time domain position is greater than or equal to X1, or, the initial position of the second time domain position is within If the time interval between the end position of the first time domain position and the end position of the first time domain position is greater than or equal to Y1, it is determined that all symbols in the second time domain position are located outside the first time window.

To sum up, the signal measurement method provided by this embodiment considers the situation that the positioning reference signal is located in the initial downlink bandwidth, and then determines the method of determining whether to measure the positioning reference signal based on this situation, so that the measurement of the positioning reference signal It is more in line with the actual application scenario.

In some other embodiments, when the positioning reference signal is located on other downlink bandwidth parts except the initial downlink bandwidth part, the terminal uses the second decision criterion to determine whether to measure the positioning reference signal, as shown in FIG. 9, step 210 may include Step 410, as follows:

Step 410, in the case of the RRC inactive state, determine whether to measure the positioning reference signal based on whether the first time domain position and the second time domain position meet the second criterion.

Wherein, the second judgment criterion includes judgment criterion type 3:

Judgment criterion type 3 includes: the second symbol in the second time domain position is within a second time window, and the second time window refers to a time window corresponding to the first time domain position.

The above-mentioned second time window is a time window corresponding to the first time domain position when the positioning reference signal is located on other downlink bandwidth parts. Optionally, the second time window includes: symbols at the first time domain position, X2 symbols before the first time domain position, and Y2 symbols after the first time domain position, where X2 and Y2 are non-negative integers. For example, the first time domain position in FIG. 10 includes symbols 5-8 on time slot 5, X2 takes a value of 0, and Y2 takes a value of 5, then the second time window is symbols 5-13.

Optionally, the X2 symbols and the Y2 symbols are determined based on the subcarrier spacing of the initial downlink bandwidth part. Exemplarily, after the terminal determines to adopt the second decision criterion, or after starting the positioning function, or after the device itself is started, it obtains the subcarrier spacing of the initial downlink bandwidth part, and determines based on the subcarrier spacing of the initial downlink bandwidth part The symbol length of each of X2 symbols and Y2 symbols, and/or X2 symbols and Y2 symbols. For example, there is a corresponding relationship between the subcarrier spacing of the initial downlink bandwidth part and X2 and Y2, and X2 and Y2 corresponding to the subcarrier spacing of the initial downlink bandwidth part are determined based on the above corresponding relationship.

Or, the X2 symbols and Y2 symbols are determined based on the subcarrier spacing of other downlink bandwidth parts except the initial downlink bandwidth part, that is, determined based on the subcarrier spacing of other downlink bandwidth parts to which the positioning reference signal belongs. Exemplarily, after the terminal determines to adopt the second decision criterion, or after starting the positioning function, or after the device itself is started, it obtains the subcarrier spacing of other downlink bandwidth parts, and determines based on the subcarrier spacing of other downlink bandwidth parts The symbol length of each of X2 symbols and Y2 symbols, and/or X2 symbols and Y2 symbols. For example, there is a corresponding relationship between the subcarrier spacing of other downlink bandwidth parts and X2 and Y2, and X2 and Y2 corresponding to the subcarrier spacing of other downlink bandwidth parts are determined based on the above corresponding relationship.

Alternatively, the X2 symbols and the Y2 symbols are determined based on the subcarrier spacing of the initial downlink bandwidth part and the time of radio frequency retuning. Exemplarily, after the terminal determines to adopt the second decision criterion, or after starting the positioning function, or after the device itself is started, it obtains the subcarrier spacing of the initial downlink bandwidth part and the time for radio frequency retuning, based on the initial downlink The subcarrier spacing of the bandwidth portion, and the timing of the RF re-tuning determine the symbol length of each of X2 symbols and Y2 symbols, and/or X2 symbols and Y2 symbols. For example, there is a corresponding relationship between the subcarrier spacing of the initial downlink bandwidth part, the time of radio frequency retuning, and X2 and Y2. Based on the above correspondence, determine the corresponding X2 and Y2 of the subcarrier spacing of other downlink bandwidth parts and the time of radio frequency retuning. .

Alternatively, the X2 symbols and the Y2 symbols are determined based on the subcarrier spacing of other downlink bandwidth parts and the time of radio frequency retuning. Exemplarily, after the terminal determines to adopt the second decision criterion, or after starting the positioning function, or after the device itself is started, it obtains the subcarrier spacing of other downlink bandwidth parts and the time of radio frequency retuning, based on other downlink The subcarrier spacing of the bandwidth portion, and the timing of the RF re-tuning determine the symbol length of each of X2 symbols and Y2 symbols, and/or X2 symbols and Y2 symbols. For example, there is a corresponding relationship between the subcarrier spacing of other downlink bandwidth parts, the time of radio frequency retuning and X2, Y2, based on the above correspondence, determine the corresponding X2 and Y2 of the subcarrier spacing of other downlink bandwidth parts and the time of radio frequency retuning .

Exemplarily, the symbol length of each symbol in the X2 symbols and the Y2 symbols is determined based on the subcarrier spacing. The values of X2 and Y2 are determined based on the subcarrier spacing and the timing of radio frequency retuning. Optionally, X2 is greater than or equal to X1, and Y2 is greater than or equal to Y1; X1 and Y1 are used to determine the first time window corresponding to the first time domain position when the positioning reference signal is located in the initial downlink bandwidth part. Because compared with X2 and Y2, X1 and Y1 do not need to include the time of RF retuning (RF retuning) when the bandwidth part is switched.

After determining X2 and Y2 based on any of the above four methods, the terminal reports its own capabilities to the access network device and/or the location server, for example, the terminal may report to the access network device and/or the location server that it supports the second determination Criteria, and report X2 and Y2. In this way, the access network device and/or the location server can clearly know the PRS received by the terminal.

Afterwards, the terminal performs step 420 to step 430 according to the judgment result, as follows:

Step 420, if the first time domain position and the second time domain position meet the second criterion, determine not to measure the positioning reference signal.

Exemplarily, if the second symbol in the second time domain position is within the second time window, the terminal determines not to measure the positioning reference signal. That is, if part or all of the symbols in the second time domain position are within the second time window, the terminal determines not to measure the positioning reference signal. For example, the first time domain position in Figure 11 includes symbols 5-8 on time slot 5, X2 takes a value of 0, and Y2 takes a value of 5, then the second time window includes symbols 5-13 on time slot 5; If the second time domain position includes symbols 10-13 on slot 5, it is determined that the second symbol in the second time domain position is within the second time window, and the terminal determines not to measure the positioning reference signal.

Step 430, if the first time domain position and the second time domain position do not meet the second determination criterion, determine the measurement positioning reference signal.

Exemplarily, if the second symbol in the second time domain position is outside the second time window, the terminal determines to measure the positioning reference signal. That is, if all the symbols in the second time domain position are outside the second time window, the terminal determines to measure the positioning reference signal. For example, the first time domain position in FIG. 12 includes symbols 5-8 on time slot 6, the second time window includes symbols 5-13 on time slot 6, and the second time domain position includes symbol 1 on time slot 6. ˜2. It is determined that the second symbol in the second time domain position is outside the second time window, and the terminal determines to measure the positioning reference signal.

It should be noted that the above X2 and Y2 may be used to indicate the time interval threshold. For example, X2 can be used to indicate the time interval threshold between the second time domain position and the initial position of the first time domain position, and Y2 can be used to indicate the time interval between the second time domain position and the end position of the first time domain position. Time interval threshold. If the end position of the second time domain position is before the initial position of the first time domain position and the time interval between the initial position of the first time domain position is greater than or equal to X2, or, the initial position of the second time domain position is within If the time interval between the end position of the first time domain position and the end position of the first time domain position is greater than or equal to Y2, it is determined that all symbols in the second time domain position are located outside the second time window.

To sum up, the signal measurement method provided by this embodiment considers the situation that the positioning reference signal is located in other downlink bandwidth parts except the initial downlink bandwidth part, and then determines whether the positioning reference signal is measured or not based on this situation. The method is different from the determination method corresponding to the initial downlink bandwidth, so that the measurement of the positioning reference signal is more in line with the actual application scenario.

In some embodiments, the access network device and/or the location server receives the determination criterion reported by the terminal. Wherein, the determination criterion is used to determine whether to measure the positioning reference signal according to the first time domain position of the downlink information and the second time domain position of the positioning reference signal when the terminal is in the radio resource control inactive state.

Exemplarily, in the case that the positioning reference signal is located on the initial downlink bandwidth part, the above-mentioned decision criterion includes at least one of decision criterion type 1 and decision criterion type 2:

Decision criterion type 1 includes overlap between the first symbol in the first time domain position and the second symbol in the second time domain position;

Determination criterion type 2 includes that the second symbol in the second time domain position is within the first time window, and the first time window refers to the time window corresponding to the first time domain position.

Wherein, the first time window includes: symbols at the first time domain position, X1 symbols before the first time domain position, and Y1 symbols after the first time domain position, where X1 and Y1 are non-negative integers. The X1 symbols and the Y1 symbols are determined based on the subcarrier spacing of the initial downlink bandwidth part. If the terminal determines X1 and Y1 based on the above subcarrier spacing, it also reports X1 and Y1 to the access network device and/or location server, and accordingly, the access network device and/or location server receives X1 and Y1 reported by the terminal.

Exemplarily, in the case that the positioning reference signal is located on other downlink bandwidth parts except the initial downlink bandwidth part, the above-mentioned decision criterion includes decision criterion type 3; decision criterion type 3 includes the second symbol in the second time domain position Located within the second time window, the second time window refers to the time window corresponding to the first time domain position.

If the terminal determines X2 and Y2 based on the above subcarrier spacing and/or radio frequency retuning time, it also reports X2 and Y2 to the access network device and/or location server, and accordingly, the access network device and/or location server receives X2 and Y2 reported by the terminal.

To sum up, if the access network device (mainly the access network device side to which the serving cell of the terminal belongs) can pass the above-mentioned terminal capabilities reported by the terminal or the location server, it is determined that the terminal cannot measure the positioning reference signal, and then there is no need to send a positioning reference signal. However, since the access network equipment side to which the adjacent cell of the terminal belongs does not know the sending time of the downlink information of the serving cell of the terminal, the adjacent cell will continue to send, but the terminal cannot receive it due to a conflict.

Exemplarily, the signal measurement method provided by this application is described as follows:

Firstly, the terminal determines the first time domain position of the downlink channel/signal and the second time domain position of the PRS, and determines whether to receive the PRS according to the judgment criterion.

A) The downlink channel and/or signal contains at least one of the following:

Control resource set 0 (COntrol REsource SET 0, CORESET0);

paging;

Downlink Small Data Transmission (DownLink Small Data Transmission, DL SDT).

B) The UE is in the RRC_INACTIVE state, that is, the RRC inactive state.

Second, the judgment criteria include at least one of the following:

Judgment criterion type 1: only the PRS and the downlink channel/signal overlap on a certain symbol, then it is determined that there is a reception conflict between the two, and the terminal receives the downlink channel/signal but does not receive the PRS.

Judgment criterion type 2: define a time window, that is, the first time window, whose starting position is X1 symbols/slot (time slot) before the downlink channel/signal, and whose end position is Y1 symbols after the downlink channel/signal /slot. That is, this time window includes the symbol where the downlink channel/signal is located, X1 symbols before the downlink channel/signal and Y1 symbols after it.

Judgment criterion type 3: define a time window, that is, the second time window, whose starting position is X2 symbols/slot before the downlink channel/signal, and whose end position is Y2 symbols/slot after the downlink channel/signal. That is, this time window includes the symbol where the downlink channel/signal is located, X2 symbols before the downlink channel/signal and Y2 symbols after it.

Among them, judging

criterion types

1 and 2 are applicable to PRS located inside initial DL BWP; judging criterion type 3 is applicable to PRS located outside initial DL BWP.

Third, the terminal reports UE capability (that is, terminal capability) to at least one of LMF and gNB:

A) For the PRS located in the initial DL BWP, the terminal selects at least one of the

judgment criterion types

1 and 2 to report. If the judgment criterion type 2 is reported, the values of X1 and Y1 need to be further reported.

The X1 and Y1 are determined based on the subcarrier spacing (Subcarrier Spacing, SCS) of the initial DL BWP.

B) For the PRS located outside the initial DL BWP, the terminal reports the values of X2 and Y2.

Its X2 and Y2 are determined based on the SCS of the initial DL BWP or based on the SCS of the BWP where the PRS is located.

Wherein, X2>=X1, Y2>=Y1. Because the PRS in decision criterion type 3 is different from the BWP of other channels/signals (always located in the initial DL BWP), RF retuning time is also required.
