[0044] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.
[0045] Figure 1 A block diagram of a communication system provided by an exemplary embodiment of the present disclosure is shown. The communication system may include: an access network 12, a user terminal 14 and a core network device 16.
[0046] The access network 12 includes several access network devices 120. The access network device 120 may be a base station, which is a device deployed in the access network to provide wireless communication functions for user terminals (referred to as "terminals") 14. The base station may include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems using different wireless access technologies, the names of devices with base station functions may be different, for example, in the Long Term Evolution (LTE) system, it is called eNodeB or eNB; in the 5G NR (New Radio) system, it is called gNodeB or gNB. With the evolution of communication technology, the description of "base station" may change. In the positioning system, a transmission reception point (TRP) is also introduced. Each access network device may include at least one TRP, and multiple TRPs send positioning reference signals. The terminal measures the positioning reference signals sent by multiple TRPs and reports the measurement results, wherein some of these TRPs are sent by the access network device to which the service cell of the terminal belongs, and some are sent by the access network device to which the neighboring cell (i.e., non-service cell) of the terminal belongs. To facilitate the description in the embodiments of the present disclosure, the above-mentioned devices that provide wireless communication functions for the user terminal 14 are collectively referred to as network devices.
[0047] The 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 a wireless modem, as well as various forms of user equipment, mobile stations (MS), terminal devices, etc. For ease of description, the above-mentioned devices are collectively referred to as user terminals. The access network device 120 and the user terminal 14 communicate with each other through some air interface technology, such as a Uu interface.
[0048] The core network device 16 includes a location management function network element. Optionally, the location management function network element includes a location server, which can be implemented as any one of the following: LMF (Location Management Function, location management network element), E-SMLC (Enhanced Serving Mobile Location Centre, enhanced serving mobile location centre), SUPL (Secure User Plane Location, secure user plane location), SUPL SLP (SUPL Location Platform, secure user plane location location platform). LPP (LTE Positioning Protocol, LTE positioning protocol) is used for communication transmission between the terminal device and the location server.
[0049] 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, 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 (TDD) system, Advanced Long Term Evolution (LTE-A) system, New Radio (NR) system, NR system evolution system, 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 Network (WLAN) system. Networks, WLAN), Wireless Fidelity (WiFi), next generation communication systems or other communication systems, etc.
[0050] Generally speaking, the number of connections supported by traditional communication systems is limited and easy to implement. However, with the development of communication technology, mobile communication systems will not only support traditional communications, but also support, for example, device to device (D2D) communication, machine to machine (M2M) communication, machine type communication (MTC), vehicle to vehicle (V2V) communication and vehicle to everything (V2X) system, etc. The embodiments of the present disclosure can also be applied to these communication systems.
[0051] Figure 2A method flow chart of a signal measurement method provided by an exemplary embodiment of the present disclosure is shown. Figure 1 In a terminal of the communication system shown in FIG. 1 , the method includes:
[0052] Step 210: When the RRC is in an 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.
[0053] Downlink information refers to information sent by access network equipment, and downlink information includes downlink channels and / or signals.
[0054] Exemplarily, the downlink channel and / or signal includes at least one of the following:
[0055] Physical downlink control channel (PDCCH);
[0056] Physical downlink shared channel (PDSCH);
[0057] Synchronization Signal / PBCH Block (SSB), including Primary Synchronization Signal (PSS), Secondary Synchronization Signal (SSS), Physical Broadcast Channel (PBCH) and PBCH Demodulation Reference Signal (DMRS);
[0058] System Information Block 1 (SIB1);
[0059] Control resource set 0 (COntrol REsource SET 0, CORESET0);
[0060] Message 2 (Msg2), i.e., the random access response of the second step in the four-step random access process;
[0061] Message B (MsgB), i.e., the random access response of the second step in the two-step random access process;
[0062] Paging;
[0063] Downlink Small Data Transmission (DL SDT).
[0064] Exemplarily, when the terminal is in an RRC inactive state, the downlink information is sent by the access network device on an initial downlink bandwidth part (initial Downlink BandWidth Part, initial DL BWP) of the terminal.
[0065] Exemplarily, when the terminal is in an RRC inactive state, it obtains the first time domain position of the downlink information and the second time domain position of the positioning reference signal, the first time domain position refers to the time domain resources occupied by the access network device when sending downlink information to the terminal in the downlink scenario, and the second time domain position refers to the time domain resources occupied by the access network device when sending PRS to the terminal in the downlink scenario; then the terminal determines whether the time domain resources respectively occupied by the downlink information and the positioning reference signal overlap partially or completely based on the first time domain position and the second time domain position, that is, determines whether there is a reception conflict between the downlink information and the positioning reference signal, and then determines whether to measure the positioning reference signal based on whether there is a reception conflict between the downlink information and the positioning reference signal. The above reception conflict refers to the partial or complete overlap between the time domain resources required to receive the downlink information and the time domain resources required to receive the PRS, or the time interval is less than the time interval threshold (that is, the time interval is small).
[0066] Exemplarily, the first time domain position and / or the second time domain position is configured for the terminal by the access network device; or, is configured for the terminal by the location server.
[0067] Exemplarily, the 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 time domain positions on different bandwidth parts (Bandwidth Part, BWP).
[0068] Exemplarily, the terminal determines, based on the first time domain position and the second time domain position, that there is partial overlap or full overlap between the time domain resources respectively occupied by the downlink information and the positioning reference signal, or the time interval is less than the time interval threshold, that is, it determines that there is a reception conflict between the downlink information and the positioning reference signal, and then the positioning reference signal is not measured; based on the first time domain position and the second time domain position, it determines that there is no overlap between the time domain resources respectively occupied by the downlink information and the positioning reference signal, or the time interval is greater than or equal to the time interval threshold, that is, it determines that there is no reception conflict between the downlink information and the positioning reference signal, and then the positioning reference signal is measured.
[0069] To summarize, the signal measurement method provided in this embodiment enables the terminal to determine whether there is a reception conflict between the downlink information and the positioning reference signal based on 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 an RRC inactive state, thereby providing a decision criterion for selecting whether to measure or not measure the positioning reference signal, that is, whether to measure the positioning reference signal.
[0070] The positioning reference signal may be located on the initial downlink bandwidth part, that is, on the same DLBWP as the downlink information; the positioning reference signal may also be located on other downlink bandwidth parts except the initial downlink bandwidth part. For the above two different scenarios, the terminal determines whether to measure the positioning reference signal in different ways.
[0071] In some embodiments, when the positioning reference signal is located in the initial downlink bandwidth part, the terminal uses a first decision criterion to determine whether to measure the positioning reference signal, such as Figure 3 , step 210 may include step 310, as follows:
[0072] Step 310: When the RRC is in an inactive state, determine whether to measure a positioning reference signal based on whether the first time domain position and the second time domain position meet a first determination criterion.
[0073] The first determination criterion includes at least one of determination criterion type 1 and determination criterion type 2:
[0074] Decision criterion type 1 includes: there is an overlap between a first symbol in a first time domain position and a second symbol in a second time domain position;
[0075] Determination criterion type 2 includes: the second symbol in the second time domain position is located within the first time window, and the first time window refers to the time window corresponding to the first time domain position.
[0076] The first time window is a time window corresponding to the first time domain position when the positioning reference signal is located on the initial downlink bandwidth portion. Optionally, the first time window includes the symbol 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.
[0077] For example, Figure 4 , a time slot 0 includes 14 symbols 0 to 13. Assuming that the first time domain position of the downlink information is symbols 4 to 8 on time slot 0, X1 is 2, Y1 is 1, and the terminal determines that the first time window is symbols 2 to 9 on time slot 0.
[0078] Optionally, X1 symbols and Y1 symbols are determined based on the subcarrier spacing of the initial downlink bandwidth part. Exemplarily, after the terminal determines to adopt determination criterion type 2, or after starting the positioning function, or after the device itself starts, it obtains the subcarrier spacing of the initial downlink bandwidth part, and determines the symbol length of each symbol in X1 symbols and Y1 symbols and / or X1 symbols and Y1 symbols based on the subcarrier spacing of the initial downlink bandwidth part. For example, there is a corresponding relationship between the subcarrier spacing of the initial downlink bandwidth part and X1, Y1, and X1 and Y1 corresponding to the subcarrier spacing of the initial downlink bandwidth part are determined based on the above corresponding relationship.
[0079] After determining the values of X1 and Y1, the terminal reports its own capabilities to the access network device and / or the location server. For example, the terminal may report X1 and Y1 to the access network device and / or the location server; for another example, the terminal may also report to the access network device and / or the location server that it supports at least one of determination criterion type 1 and determination criterion type 2. In this way, the access network device and / or the location server can clearly know the PRS received by the terminal.
[0080] Afterwards, the terminal executes steps 320 to 330 according to the determination result, as shown below:
[0081] Step 320: When the first time domain position and the second time domain position meet a first determination criterion, determine not to measure the positioning reference signal.
[0082] Exemplarily, if there is a partial overlap or a 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. Figure 5 The first time domain position includes symbols 0 to 6 on time slot 1, and the second time domain position includes symbols 4 to 8 on time slot 1. Symbols 4 to 6 in the first time domain position overlap with those in the second time domain position. It is determined that the first time domain position and the second time domain position meet the judgment criterion type 1, and the terminal does not measure the positioning reference signal.
[0083] Alternatively, 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 part or all of the 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, 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 judgment criterion type 2, and the terminal does not measure the positioning reference signal.
[0084] 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 meet the determination criterion type 1 or the determination criterion type 2.
[0085] Step 330: When the first time domain position and the second time domain position do not meet the first determination criterion, determine to measure the positioning reference signal.
[0086] 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. Figure 7 The first time domain position includes symbols 1 to 3 on time slot 3, and the second time domain position includes symbols 5 to 8 on time slot 3. There is no overlap between the symbols in the first time domain position and the second time domain position. It is determined that the first time domain position and the second time domain position do not meet the symbol determination criterion type 1, and the terminal measures the positioning reference signal.
[0087] Alternatively, 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 symbols in the second time domain position are outside the first time window, the terminal determines to measure the positioning reference signal. For example, Figure 8 The first time domain position includes symbols 5 to 8 on time slot 4, and the second time domain position includes symbols 1 to 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. The terminal determines that the first time domain position and the second time domain position do not meet the judgment criterion type 2, and the terminal measures the positioning reference signal.
[0088] Optionally, 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, the terminal determines to measure the positioning reference signal.
[0089] It should be noted that the above X1 and Y1 can be used to indicate the time interval threshold. For example, X1 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 Y1 can be used to indicate the time interval threshold between the second time domain position and the end position of the first time domain position. 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 it and 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 after the end position of the first time domain position and the time interval between it and the end position of the first time domain position is greater than or equal to Y1, then it is determined that all symbols in the second time domain position are outside the first time window.
[0090] In summary, the signal measurement method provided in this embodiment takes into account the situation where the positioning reference signal is located in the initial downlink bandwidth part, 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 is more in line with actual application scenarios.
[0091] In some other embodiments, when the positioning reference signal is located in other downlink bandwidth parts except the initial downlink bandwidth part, the terminal uses a second decision criterion to determine whether to measure the positioning reference signal, such as Fig. 9 , step 210 may include step 410, as follows:
[0092] Step 410: When the RRC is in an inactive state, determine whether to measure a positioning reference signal based on whether the first time domain position and the second time domain position meet a second determination criterion.
[0093] The second judgment criterion includes judgment criterion type 3:
[0094] Judgment criterion type 3 includes: the second symbol in the second time domain position is located within the second time window, and the second time window refers to the time window corresponding to the first time domain position.
[0095] The second time window is the 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: the symbol 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, Fig.10 The first time domain position in includes symbols 5 to 8 on time slot 5, X2 takes the value of 0, Y2 takes the value of 5, and the second time window is symbols 5 to 13.
[0096] Optionally, the X2 symbols and the Y2 symbols are determined based on the subcarrier spacing of the initial downlink bandwidth part. Exemplarily, after determining to adopt the second determination criterion, or after starting the positioning function, or after the device itself is started, the terminal obtains the subcarrier spacing of the initial downlink bandwidth part, and determines the symbol length of each symbol in the X2 symbols and the Y2 symbols and / or the X2 symbols and the Y2 symbols based on the subcarrier spacing of the initial downlink bandwidth part. 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.
[0097] Alternatively, the X2 symbols and the Y2 symbols are determined based on the subcarrier spacing of other downlink bandwidth parts except the initial downlink bandwidth part, that is, 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 determination criterion, or after starting the positioning function, or after the device itself starts, it obtains the subcarrier spacing of other downlink bandwidth parts, and determines the symbol length of each symbol of the X2 symbols and the Y2 symbols and / or the X2 symbols and the Y2 symbols based on the subcarrier spacing of other downlink bandwidth parts. 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.
[0098] 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 re-tuning. Exemplarily, after determining to adopt the second determination criterion, or after starting the positioning function, or after the device itself is started, the terminal obtains the subcarrier spacing of the initial downlink bandwidth part and the time of radio frequency re-tuning, and determines the symbol length of each symbol of the X2 symbols and the Y2 symbols and / or the X2 symbols and the Y2 symbols based on the subcarrier spacing of the initial downlink bandwidth part and the time of radio frequency re-tuning. For example, there is a corresponding relationship between the subcarrier spacing of the initial downlink bandwidth part, the time of radio frequency re-tuning, and X2 and Y2, and based on the above corresponding relationship, X2 and Y2 corresponding to the subcarrier spacing of other downlink bandwidth parts and the time of radio frequency re-tuning are determined.
[0099] 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 re-tuning. Exemplarily, after the terminal determines to adopt the second determination criterion, or after starting the positioning function, or after the device itself starts, it obtains the subcarrier spacing of other downlink bandwidth parts and the time of radio frequency re-tuning, and determines the symbol length of each symbol of the X2 symbols and the Y2 symbols and / or the X2 symbols and the Y2 symbols based on the subcarrier spacing of other downlink bandwidth parts and the time of radio frequency re-tuning. For example, there is a corresponding relationship between the subcarrier spacing of other downlink bandwidth parts, the time of radio frequency re-tuning, and X2 and Y2, and X2 and Y2 corresponding to the subcarrier spacing of other downlink bandwidth parts and the time of radio frequency re-tuning are determined based on the above corresponding relationship.
[0100] 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 time of RF 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 X1 and Y1 do not need to include the time of RF retuning when the bandwidth part is switched compared with X2 and Y2.
[0101] After the terminal determines X2 and Y2 based on any of the above four methods, it reports its own capabilities to the access network device and / or the location server. For example, the terminal can report to the access network device and / or the location server that it supports the second determination criterion and reports X2 and Y2. In this way, the access network device and / or the location server can clearly know the PRS received by the terminal.
[0102] Afterwards, the terminal executes steps 420 to 430 according to the determination result, as shown below:
[0103] Step 420: When the first time domain position and the second time domain position meet a second determination criterion, determine not to measure the positioning reference signal.
[0104] Exemplarily, if the second symbol in the second time domain position is located 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 located within the second time window, the terminal determines not to measure the positioning reference signal. For example, Fig.11 The first time domain position includes symbols 5 to 8 on time slot 5, X2 takes the value of 0, and Y2 takes the value of 5, then the second time window includes symbols 5 to 13 on time slot 5; the second time domain position includes symbols 10 to 13 on time slot 5, then 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.
[0105] Step 430: When the first time domain position and the second time domain position do not meet the second determination criterion, determine to measure the positioning reference signal.
[0106] 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 symbols in the second time domain position are outside the second time window, the terminal determines to measure the positioning reference signal. For example, Fig.12The first time domain position includes symbols 5 to 8 on time slot 6, the second time window includes symbols 5 to 13 on time slot 6, the second time domain position includes symbols 1 to 2 on time slot 6, and 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.
[0107] It should be noted that the above X2 and Y2 can 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 threshold between the second time domain position and the end position of the first time domain position. 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 it and 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 after the end position of the first time domain position and the time interval between it and the end position of the first time domain position is greater than or equal to Y2, then it is determined that all symbols in the second time domain position are outside the second time window.
[0108] To sum up, the signal measurement method provided in this embodiment takes into account the situation that the positioning reference signal is located in other downlink bandwidth parts except the initial downlink bandwidth part, and then determines the determination method of whether to measure the positioning reference signal based on this situation. The determination 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.
[0109] In some embodiments, the access network device and / or the location server receives the determination criteria reported by the terminal, wherein the determination criteria 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 a radio resource control inactive state.
[0110] Exemplarily, in the case where the positioning reference signal is located on the initial downlink bandwidth part, the above-mentioned determination criterion includes at least one of determination criterion type 1 and determination criterion type 2:
[0111] Decision criterion type 1 includes that there is an overlap between a first symbol in a first time domain position and a second symbol in a second time domain position;
[0112] The determination criterion type 2 includes that the second symbol in the second time domain position is located within the first time window, and the first time window refers to the time window corresponding to the first time domain position.
[0113] The first time window includes: a symbol 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. X1 symbols and Y1 symbols are determined based on the subcarrier spacing of the initial downlink bandwidth. 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 the location server, and accordingly, the access network device and / or the location server receives X1 and Y1 reported by the terminal.
[0114] Exemplarily, in the case where the positioning reference signal is located on other downlink bandwidth parts other than the initial downlink bandwidth part, the above-mentioned determination criteria include determination criterion type 3; determination criterion type 3 includes that the second symbol in the second time domain position is located within the second time window, and the second time window refers to the time window corresponding to the first time domain position.
[0115] The second time window includes: a symbol 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. X2 symbols and Y2 symbols are determined based on the subcarrier spacing of the initial downlink bandwidth part; or, 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, based on the subcarrier spacing of the downlink bandwidth part where the positioning reference signal is located; or, X2 symbols and Y2 symbols are determined based on the subcarrier spacing of the initial downlink bandwidth part and the time of radio frequency retuning; or, X2 symbols and Y2 symbols are determined based on the subcarrier spacing of other downlink bandwidth parts (that is, based on the subcarrier spacing of the downlink bandwidth part where the positioning reference signal is located) and the time of radio frequency retuning. If the terminal determines X2 and Y2 based on the above-mentioned subcarrier spacing and / or RF retuning time, it also reports X2 and Y2 to the access network device and / or location server. Accordingly, the access network device and / or location server receives X2 and Y2 reported by the terminal.
[0116] In summary, if the access network device (mainly the access network device side to which the terminal's service cell belongs) can determine that the terminal cannot measure the positioning reference signal through the above terminal capabilities reported by the terminal or the location server, then there is no need to send the positioning reference signal. However, since the access network device side to which the terminal's neighboring cell belongs does not know the sending time of the downlink information of the terminal's service cell, the neighboring cell will continue to send it, but the terminal cannot receive it due to the conflict.
[0117] Exemplarily, the signal measurement method provided in this application is described as follows:
[0118] First, the terminal determines a first time domain position of a downlink channel / signal and a second time domain position of a PRS, and determines whether to receive the PRS according to a judgment criterion.
[0119] A) Downlink channels and / or signals include at least one of the following:
[0120] Synchronization Signal / PBCH Block (SSB), including Primary Synchronization Signal (PSS), Secondary Synchronization Signal (SSS), PBCH is the Physical Broadcast Channel and the DeModulation Reference Signal (DMRS) of PBCH;
[0121] System Information Block 1 (SIB1);
[0122] Control resource set 0 (COntrol REsource SET 0, CORESET0);
[0123] Message 2 (Msg2), i.e., the random access response of the second step in the four-step random access process;
[0124] Message B (MsgB), i.e., the random access response of the second step in the two-step random access process;
[0125] Paging;
[0126] Downlink Small Data Transmission (DL SDT).
[0127] B) The UE is in RRC_INACTIVE state, that is, RRC is inactive.
[0128] Second, the judgment criteria include at least one of the following:
[0129] Decision criterion type 1: If only the PRS and the downlink channel / signal overlap in a certain symbol, 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.
[0130] Decision criterion type 2: Define a time window, i.e., the first time window, whose starting position is X1 symbols / slots (time slots) before the downlink channel / signal and whose ending position is Y1 symbols / slots after the downlink channel / signal. That is, this time window includes the symbol where the downlink channel / signal is located, as well as X1 symbols before and Y1 symbols after the downlink channel / signal.
[0131] Decision criterion type 3: Define a time window, i.e., the second time window, whose starting position is X2 symbols / slots before the downlink channel / signal and whose ending position is Y2 symbols / slots after the downlink channel / signal. That is, this time window includes the symbol where the downlink channel / signal is located, as well as the X2 symbols before and the Y2 symbols after the downlink channel / signal.
[0132] Among them, decision criterion types 1 and 2 are applicable when the PRS is located within the initial DL BWP; decision criterion type 3 is applicable when the PRS is located outside the initial DL BWP.
[0133] Third, the terminal reports the UE capability (i.e., terminal capability) to at least one of the LMF and the gNB:
[0134] A) When the PRS is located in the initial DL BWP, the terminal selects at least one of the decision criteria types 1 and 2 for reporting. If the decision criteria type 2 is reported, the values of X1 and Y1 need to be further reported.
[0135] Its X1 and Y1 are determined based on the subcarrier spacing (SCS) of the initial DL BWP.
[0136] B) When the PRS is outside the initial DL BWP, the terminal reports the values of X2 and Y2.
[0137] Its X2 and Y2 are determined based on the SCS of the initial DL BWP or the SCS of the BWP where the PRS is located.
[0138] Wherein, X2>=X1, Y2>=Y1. Because the BWP of PRS and other channels / signals (always located within the initial DL BWP) in decision criterion type 3 are different, RF retuning time is also required.
