[0030] In order to better understand the method and apparatus for determining a measurement time disclosed in the embodiments of the present disclosure, the following first describes a communication system to which the embodiments of the present disclosure are applied.

[0031] Referring to FIG. 1, FIG. 1 is a schematic diagram of a communication system provided by an embodiment of the present disclosure. As shown in FIG. 1, the communication system may include an access network device, a plurality of terminal devices, and a core network device. The access network devices communicate with each other in a wired or wireless manner, for example, through an Xn interface in FIG. 1. The access network devices may cover one or more cells, for example, the access network device 1 covers cell 1.1 and cell 1.2, and the access network device 2 covers cell 2.1. The terminal device may make the access network device stay in one of the cells and put it into a connected state. Furthermore, the terminal device may convert from a connected state to an inactive state, i.e., convert to a non-connected state, through an RRC release process. The terminal device in the non-connected state may stay in the original cell, and perform uplink transmission and / or downlink transmission with the access network device in the original cell based on the transmission parameters of the terminal device in the original cell. A terminal device in an unconnected state may move to a new cell and perform uplink and / or downlink transmissions with an access network device of the new cell based on transmission parameters of the terminal device in the new cell.

[0032] It should be noted that Fig. 1 is an exemplary block diagram, and the number of nodes, the number of cells, and the state of terminals included in Fig. 1 are not limited. In addition to the functional nodes shown in Fig. 1, other nodes may be included, such as, but not limited to, a core network device, a gateway device, and an application server. The access network device communicates with the core network device in a wired or wireless manner, for example, via a next generation (NG) interface.

[0033] The access network device mainly realizes at least one function of resource scheduling, radio resource management, and radio resource control of the terminal device. Specifically, the access network device may include any one of a base station, a radio access point, a transmission reception point (TRP), a transmission point (TP) and other access nodes. In the embodiments of the present disclosure, a device capable of realizing the function of an access network device may be an access network device, or may be a device supporting the realization of the function by the access network device, such as a chip system, the device may be installed in the access network device, or may be used in combination with the access network device. In the technical solution provided by the embodiments of the present disclosure, the technical solution provided by the embodiments of the present disclosure is described by taking the device realizing the function of the access network device as an example that the device is an access network device.

[0034] Here, the core network device may include an AMF and / or a location management function network element. Optionally, the location management function network element includes a location server, which may be realized as any one of a Location Management Function (LMF), an Enhanced Serving Mobile Location Centre (E-SMLC), a Secure User Plane Location (SUPL), and a SUPL Location Platform (SUPL SLP).

[0035] The terminal device is a user-side entity for transmitting and receiving signals, such as a mobile phone. The terminal device is called a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. The terminal device may be an automobile with a communication function, a smart car, a mobile phone, a wearable device, a tablet (Pad), a computer with a wireless transmission and reception function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, etc. The embodiments of the present disclosure do not limit the specific technology and the specific device form used by the terminal device.

[0036] The AMF network element is mainly responsible for tasks such as terminal device access authentication, mobility management, and signaling interaction between each functional network element, and manages, for example, user registration status, user connection status, user registration to the network, tracking area updates, cell switching user authentication, and key security.

[0037] The LMF network element is primarily used to provide location services for terminal devices and other devices.

[0038] It should be noted that the technical solutions of the embodiments of the present disclosure can be applied to various communication systems, such as long term evolution (LTE) systems, 5th generation (5G) mobile communication systems, 5G new radio (NR) systems, or other future new mobile communication systems. It should be noted that the side link in the embodiments of the present disclosure may be referred to as a pass-through link.

[0039] It should be noted that the communication system described in the embodiment of the present disclosure is for more clearly explaining the technical solution of the embodiment of the present disclosure, and does not limit the technical solution provided by the embodiment of the present disclosure. As those skilled in the art can understand, with the evolution of system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present disclosure can also be applied to similar technical problems.

[0040] The related art provides a carrier phase-based positioning method, which measures and reports positioning based on the fractional part and full revolutions of the carrier phase. Here, the fractional part of the carrier phase refers to a fractional part less than one revolution, which is a part of the phase difference between a reference signal generated by the receiving side and a carrier signal from a transmitting point that is less than one revolution, or a part of the phase of the carrier signal from a transmitting point received by the receiving side that is less than one revolution. The full revolutions corresponds to the number of full revolutions excluding the fractional part that is less than one revolution. Since the full revolutions of the carrier phase have a problem of being unclear, there is still a lot of room for improvement in the positioning measurement accuracy.

[0041] In the present disclosure, in order to solve the problem that the full number of revolutions is not clear, multi-carrier frequencies are introduced into NR (New Radio access technology). By transmitting positioning signals at multiple carrier frequencies, the wavelengths of the multiple carrier frequencies are different, but the transmission distances they pass through are the same, so the problem that the full number of revolutions is not clear can be well solved. However, for multi-carrier frequencies, how to set a measurement time for the positioning signal of the multi-carrier frequencies is a problem to be solved. Here, the measurement time may include a measurement gap (MG) and a processing window. At present, there is no related method yet.

[0042] Based on this, embodiments of the present disclosure provide a method and apparatus for determining a measurement time, thereby solving at least the problems existing in the related art.

[0043] Please refer to FIG. 2, which is a flowchart of a measurement time determination method provided by an embodiment of the present disclosure.

[0044] As shown in FIG. 2, the method is applied to a terminal device, and the method may include, but is not limited to, the following steps S21 to S22.

[0045] S21, receiving positioning setting information of a network side device, where the positioning setting information indicates at least two carrier frequency information of a positioning signal.

[0046] In an embodiment of the present disclosure, a terminal device receives positioning setting information of a network side device, and the positioning setting information indicates at least two carrier frequency information of a positioning signal, so that the terminal device determines that the at least two carrier frequency information is available for transmitting and receiving the positioning signal.

[0047] In some embodiments, the positioning signal includes a Positioning Reference Signal (PRS) or other positioning signal.

[0048] Of course, in the embodiments of the present disclosure, the positioning signal may be other signals than PRS, and may be other new positioning signals as technology continues to advance, and the embodiments of the present disclosure are not specifically limited in this regard.

[0049] In some embodiments, the network side device may include at least one of a core network device and an access network device.

[0050] The core network device in the embodiment of the present disclosure may include a location management function network element. Optionally, the location management function network element includes a location server, which may be realized as any one of a Location Management Function (LMF), an Enhanced Serving Mobile Location Centre (E-SMLC), a Secure User Plane Location (SUPL), and a SUPL Location Platform (SUPL SLP).

[0051] S22, receiving a measurement time setting parameter sent from a network side device, where the measurement time setting parameter indicates a measurement time of the positioning signal.

[0052] In an embodiment of the present disclosure, a terminal device receives positioning setting information transmitted from a network side device, obtains at least two carrier frequency information usable for transmitting and receiving a positioning signal, and based on this, receives a measurement time setting parameter transmitted from the network side device, and when the measurement time setting parameter indicates a measurement time of the positioning signal, determines that at least two carrier frequency information are usable for transmitting and receiving the positioning signal and the measurement time for measuring the positioning signal. Thus, the terminal device can measure positioning signals of multiple carrier frequencies within a specified time range of the measurement time, and the accuracy of positioning can be improved.

[0053] In some embodiments, the positioning signals are used in a carrier phase based positioning method.

[0054] In the carrier phase-based positioning method, the contents to be measured and reported include at least one of the fractional part and the number of full revolutions of the carrier phase. The fractional part of the carrier phase refers to a fractional part less than one full revolution, and is a part of the difference between the phase of a reference signal generated by the receiving side (terminal device or network side device) and the phase of a carrier signal from a transmitting point (network side device or terminal device) that is less than one revolution, or a part of the phase of a carrier signal from a transmitting point received by the receiving side that is less than one revolution. The number of full revolutions corresponds to the number of full revolutions other than the fractional part that is less than one revolution.

[0055] In addition, the network side device transmits positioning setting information to the terminal device, and the positioning setting information indicates at least two carrier frequency information of the positioning signal, and the network side device transmits a measurement time setting parameter to the terminal device, thereby indicating the measurement time of the positioning signal at the at least two carrier frequencies.

[0056] When the positioning signals of at least two carrier frequencies are transmitted simultaneously, the at least two carrier frequencies may be set to the measurement interval MG simultaneously, or the at least two carrier frequencies may be set to the processing window simultaneously.

[0057] In some embodiments, when positioning signals of at least two carrier frequencies are transmitted at different times, one carrier frequency of the at least two carrier frequencies may be set to the measurement interval MG, and the other carrier frequency of the at least two carrier frequencies may be set to the processing window.

[0058] By way of example, when the positioning signals of the two carrier frequencies are transmitted at different times, one of the two carrier frequencies may be set to the measurement interval MG, and the other of the two carrier frequencies may be set to the processing window.

[0059] In an embodiment of the present disclosure, the positioning signal is measured using a carrier phase-based positioning method, and when it is determined that at least two carrier frequency information is available for the positioning signal and the measurement time for measuring the positioning signal, since the wavelengths of the multiple carrier frequencies are different but the transmission distances traveled are the same, the measurement accuracy of the positioning signal can be improved by measuring the positioning signal of at least two carrier frequencies.

[0060] Please refer to FIG. 3, which is a flowchart of another measurement time determining method provided by an embodiment of the present disclosure.

[0061] As shown in FIG. 3, the method is applied to a terminal device, and the method may include, but is not limited to, the following steps S31 to S32.

[0062] S31, receiving positioning setting information of a network side device, where the positioning setting information indicates at least two carrier frequency information of a positioning signal.

[0063] Here, for the relevant explanation of S31 in the embodiment of the present disclosure, please refer to the relevant explanation in the above embodiment, and similar explanations will be omitted here.

[0064] S32, receiving first indication information of a network side device, where the first indication information indicates one or more sets of measurement intervals MG.

[0065] In addition, in an embodiment of the present disclosure, the terminal device receives first instruction information transmitted from the network side device, the first instruction information instructs one or more sets of measurement intervals MG, and the terminal device may use the same measurement interval MG when transmitting, receiving or measuring positioning signals of at least two carrier frequencies, or may use multiple measurement intervals MG to use different measurement intervals MG when transmitting, receiving or measuring positioning signals of at least two carrier frequencies.

[0066] In some embodiments, the first indication information includes a first radio resource control (RRC) indicating parameter information for each set of MGs.

[0067] In an embodiment of the present disclosure, the first indication information includes a first RRC (Radio Resource Control) and indicates parameter information of each set MG via the first RRC.

[0068] In addition, when the first instruction information indicates one set of measurement interval MG, the first RRC indicates parameter information of the one set of MG, and when the first instruction information indicates multiple sets of measurement interval MG, the first RRC indicates parameter information of each set of MG among the multiple sets of MG.

[0069] In some embodiments, the first RRC further indicates the carrier frequencies to which each set of MG applies.

[0070] In addition, when the first instruction information indicates one measurement interval MG, the first RRC further indicates a carrier frequency to which the one set of MG is applied, and when the first instruction information indicates multiple sets of measurement interval MG, the first RRC further indicates a carrier frequency to which each MG of the multiple sets of MG is applied, where the carrier frequency to which each MG of the multiple sets of MG is applied may be the same or different.

[0071] In an embodiment of the present disclosure, a terminal device receives first indication information of a network side device, the first indication information includes a first radio resource control (RRC), the first indication information indicates one or multiple sets of measurement interval MGs, if the first indication information indicates one set of measurement interval MGs, the first RRC indicates parameter information and available carrier frequencies of the one set of MGs, if the first indication information indicates multiple sets of measurement interval MGs, the first RRC indicates parameter information and available carrier frequencies of each set of MGs among the multiple sets of MGs, where the carrier frequencies to which each set of MGs among the multiple sets of MGs are applied may be the same or different, so that the terminal device can determine the configuration of MGs that needs to be used to measure positioning signals at different carrier frequencies based on the first indication information, and can measure the positioning signals at the carrier frequencies using the configuration of MGs.

[0072] Exemplarily, a terminal device receives positioning configuration information of a network side device, where the positioning configuration information indicates two carrier frequencies F1 and F2 of the positioning signal, and the terminal device receives first indication information of the network side device, where the first indication information includes a first RRC, where the first RRC indicates two sets of MG parameter information and the carrier frequency to which each set MG is applied, for example, the first RRC indicates that the first set of MG parameter information is available for carrier frequency F1, and indicates that the second set of MG parameter information is available for carrier frequency F2, so that the terminal device can determine which set of MG parameter information each of carrier frequency F1 and carrier frequency F2 corresponds to, and measure the positioning signal at the carrier frequency using the parameter information of the corresponding MG respectively.

[0073] Of course, in the above example, assuming that the first RRC indicates parameter information of a set of MGs and the carrier frequencies to which the MGs of the set are applied, and the first RRC indicates that the MGs of the set are applied to carrier frequencies F1 and F2, the terminal device can determine the parameter information of the MGs of the set corresponding to both carrier frequency F1 and carrier frequency F2, thereby measuring the positioning signal at the carrier frequency using the parameter information of each corresponding MG.

[0074] It should be noted that the above example is merely an example to help understand the present solution, and does not specifically limit the embodiments of the present disclosure. The positioning setting information of the network side device may include three or more carrier frequency information.

[0075] In some embodiments, the first indication information includes a second RRC and a first media access control control element MAC CE, where the second RRC configures multiple MG IDs and parameter information of MGs corresponding to each MG ID, and the first MAC CE indicates the activated one or more MG IDs.

[0076] In an embodiment of the present disclosure, the first indication information includes a second RRC and a first MAC CE (Medium Access Control Element).

[0077] The second RRC sets multiple MG IDs and parameter information of the MG corresponding to each MG ID.

[0078] In an embodiment of the present disclosure, a terminal device receives first indication information sent from a network side device, the first indication information includes a second RRC and a first MAC CE, the second RRC sets multiple MG IDs and parameter information of MG corresponding to each MG ID, and the first MAC CE indicates one or more activated MG IDs.

[0079] When the first instruction information indicates one set of measurement interval MGs, the second RRC in the first instruction information can set multiple MG IDs and MG parameter information corresponding to each MG ID, and the first MAC CE in the first instruction information can indicate one activated MG ID, thus the first instruction information indicates the MG parameter information corresponding to the activated MG ID and indicates one set of MG parameter information.

[0080] Here, when the first instruction information indicates multiple sets of measurement interval MGs, the second RRC in the first instruction information can set multiple MG IDs and MG parameter information corresponding to each MG ID, and the first MAC CE in the first instruction information can indicate multiple activated MG IDs, thus the first instruction information indicates MG parameter information corresponding to the activated multiple MG IDs and indicates multiple sets of MG parameter information.

[0081] For example, when the first instruction information indicates a set of measurement interval MGs, the second RRC in the first instruction information may set three MG IDs and MG parameter information corresponding to each MG ID, whereas the first MAC CE in the first instruction information may instruct to activate the second MG ID among the three MG IDs, and thus the first instruction information may indicate a set of MG parameter information by indicating the MG parameter information corresponding to the second MG ID among the activated three MG IDs.

[0082] Of course, the first instruction information may further indicate two sets of measurement interval MGs, and the second RRC in the first instruction information can set five MG IDs and MG parameter information corresponding to each MG ID, and the first MAC CE in the first instruction information can instruct to activate the second and third MG IDs among the five MG IDs, so that the first instruction information can indicate two sets of MG parameter information by indicating the MG parameter information corresponding to the second and third MG IDs among the activated five MG IDs.

[0083] It should be noted that the above example is merely an example for helping to understand the present solution, and does not specifically limit the embodiments of the present disclosure. The first indication information may indicate three or more sets of measurement interval MGs, and the second RRC may set multiple MG IDs.

[0084] In some embodiments, the first MAC CE further indicates the carrier frequency to which each activated MG ID applies.

[0085] In addition, when the first instruction information indicates one set of measurement interval MG, the first MAC CE further indicates a carrier frequency to which one activated MG ID is applied, and when the first instruction information indicates multiple sets of measurement interval MG, the first MAC CE further indicates carrier frequencies to which multiple activated MG IDs are applied, where the carrier frequencies to which each MG of the multiple sets of MG is applied may be the same or different.

[0086] In an embodiment of the present disclosure, a terminal device receives first indication information of a network side device, the first indication information includes a second RRC, the first indication information indicates one or more sets of measurement interval MGs, if the first indication information indicates one set of measurement interval MGs, the second RRC in the first indication information can set multiple MG IDs and parameter information of MGs corresponding to each MG ID, the first MAC CE in the first indication information can indicate one activated MG ID and a carrier frequency to which the activated MG ID is applied, if the first indication information indicates multiple sets of measurement interval MGs, the second RRC in the first indication information can set multiple MG IDs and parameter information of MGs corresponding to each MG ID, the first MAC CE in the first indication information can indicate multiple activated MG IDs and a carrier frequency to which the activated MG ID is applied, where the carrier frequencies to which the multiple MG IDs are applied may be the same or different. Thus, the terminal device can determine the MG configuration that needs to be used to measure positioning signals at different carrier frequencies based on the first indication information, and can measure the positioning signals at the carrier frequencies using the MG configuration.

[0087] Exemplarily, a terminal device receives positioning configuration information of a network side device, where the positioning configuration information indicates two carrier frequencies F1 and F2 of a positioning signal, and the terminal device receives first indication information of the network side device, where the first indication information includes a second RRC and a first MAC CE, where the second RRC can set five MG IDs and MG parameter information corresponding to each MG ID, and the first MAC CE can indicate a second and third MG ID among the five activated MG IDs and a carrier frequency to which the activated second and third MG IDs are applied, for example, the first MAC CE indicates that the carrier frequency to which the second MG ID is applied is carrier frequency F1, and indicates that the carrier frequency to which the third MG ID is applied is carrier frequency F2, so that the terminal device can determine which sets of MG parameter information need to be used to measure carrier frequency F1 and carrier frequency F2, and then measure the positioning signal at the carrier frequency using the parameter information of the corresponding MG.

[0088] Of course, in the above example, the first MAC CE can indicate that one activated MG ID is applicable to carrier frequency F1 and carrier frequency F2, so that the terminal device can determine the parameter information of the MG corresponding to the one activated MG ID that needs to be used to measure carrier frequency F1 and carrier frequency F2, and then measure the positioning signal at the carrier frequency using the parameter information of the corresponding MG respectively.

[0089] It should be noted that the above example is merely an example to help understand the present solution, and does not specifically limit the embodiments of the present disclosure. The positioning setting information of the network side device may include three or more carrier frequency information.

[0090] In some embodiments, the parameter information of the MG includes at least one of a period, a slot offset value, and an interval duration length.

[0091] By way of example, the period may be 20 ms, or 40 ms, or 80 ms, or 160 ms, etc., and the gap duration may be 1 ms, 1.5 ms, 2 ms, 2.5 ms, 3 ms, 3.5 ms, 4 ms, 4.5 ms, 5 ms, 5.5 ms, 6 ms, etc.

[0092] For ease of understanding, the embodiments of the present disclosure provide an exemplary embodiment, in which a terminal device receives positioning configuration information and first indication information of a network side device, the positioning configuration information indicates two carrier frequency information of a positioning signal, the first indication information includes a first RRC, and the first RRC indicates parameter information of each set MG and a carrier frequency to which each set MG is applied, thereby indicating one or more sets of measurement interval MG.

[0093] Here, if the first indication information indicates parameter information of one set of MGs and carrier frequencies to which the set of MGs are applied, and the parameter information of the MGs includes that the period is 40 ms, the slot offset value is 2 ms, and the interval duration is 1 ms, the terminal device can determine based on the first indication information that the parameter information of the MGs corresponding to each of the two carrier frequencies of the positioning signal is that the period is 40 ms, the slot offset value is 2 ms, and the interval duration is 1 ms, so that the terminal device can receive and measure the positioning signal within a time period of 40 ms*N+2 to 40 ms*N+3 ms, where N is a non-negative integer.

[0094] In another exemplary embodiment, a terminal device receives positioning configuration information and first indication information of a network side device, where the positioning configuration information indicates two carrier frequency information of the positioning signal, the first indication information includes a second RRC and a first MAC CE, where the second RRC sets four MG IDs and parameter information of MG corresponding to each MG ID, the first MAC CE indicates to activate a first and a second MG ID among the four MG IDs, and indicates that the activated first and second MG IDs correspond to each of the two carrier frequencies of the positioning signal indicated by the positioning configuration information. Here, if the parameter information of the MG corresponding to the first activated MG ID includes a period of 20 ms, a slot offset value of 2 ms, and an interval duration of 1 ms, and the parameter information of the MG corresponding to the second activated MG ID includes a period of 40 ms, a slot offset value of 5 ms, and an interval duration of 1.5 ms, the terminal device can determine, based on the first indication information, that the parameter information of the MG corresponding to one of the two carrier frequencies of the positioning signal is a period of 20 ms, a slot offset value of 2 ms, and an interval duration of 1 ms, and that the parameter information of the MG corresponding to the other carrier frequency is a period of 40 ms, a slot offset value of 5 ms, and an interval duration of 1.5 ms.

[0095] Therefore, the terminal device can receive a positioning signal at one of the carrier frequencies and measure the positioning signal at the carrier frequency within a time period from 20ms*N+2 to 20ms*N+3ms, and receive a positioning signal at the other carrier frequency and measure the positioning signal at the carrier frequency within a time period from 40ms*M+5 to 40ms*M+6.5ms, where M and N are non-negative integers.

[0096] In an embodiment of the present disclosure, a terminal device receives a positioning signal within a periodically occurring gap duration, and can measure the positioning signal without receiving other downlink channels or signals transmitted from a network side device, such as a PDCCH (Physical Downlink Control Channel), a PDSCH (Physical Downlink Shared Channel), a CSI-RS (Channel State Information Reference Signal), a PBCH (Physical Broadcast Channel), or an SSB (synchronization signal block).

[0097] In some embodiments, when a set of MGs is applicable to at least two carrier frequencies, it measures positioning signals at different carrier frequencies within different interval durations or measures positioning signals at different carrier frequencies within the same interval duration.

[0098] Exemplarily, when one set of MGs is applied to two carrier frequencies F1 and F2, it may measure the positioning signal at F1 within the first interval duration, and measure the positioning signal at F2 within the second interval duration, or may measure the positioning signals at F1 and F2 within the first interval duration. For example, the period of this MG is 40 ms, the slot offset value is t0, and the gap duration is 6 ms, so that the first gap duration time is within t0 to t0 + 6 ms, and the second gap duration time is within t0 + 40 to t0 + 46 ms. Therefore, the terminal device may measure the positioning signal at F1 within t0 to t0 + 6 ms, and measure the positioning signal at F2 from t0 + 40 to t0 + 46 ms, or the terminal device may measure the positioning signals at F1 and F2 within t0 to t0 + 6 ms, for example, it may measure the positioning signal at F1 within t0 to t0 + 3 ms, and measure the positioning signal at F2 within t0 + 3 to t0 + 6 ms. Or the terminal device may measure the positioning signals at F1 and F2 within a time period from t0+40 to t0+46 ms, for example, measure the positioning signal at F1 within a time period from t0+40 to t0+43 ms, and measure the positioning signal at F2 within a time period from t0+43 to t0+46 ms.

[0099] Please refer to FIG. 4, which is a flowchart of another measurement time determining method provided by an embodiment of the present disclosure.

[0100] As shown in FIG. 4, the method is applied to a terminal device, and the method includes, but is not limited to, the following steps S41 to S43.

[0101] S41, receiving positioning setting information of a network side device, where the positioning setting information indicates at least two carrier frequency information of a positioning signal.

[0102] For the explanation of S41 in the embodiment of the present disclosure, please refer to the relevant explanation in the above example, and similar explanation will be omitted here.

[0103] S42, sending first request information to the network side device, where the first request information indicates an MG request.

[0104] In an embodiment of the present disclosure, a terminal device receives positioning setting information of a network side device, and the positioning setting information indicates at least two carrier frequency information of a positioning signal, so that the terminal device determines that the at least two carrier frequency information is available for transmitting and receiving the positioning signal.

[0105] In this case, the terminal device can send first request information to the network side device for indicating an MG request, which may be understood as requesting the network side device to indicate the configuration of the MG.

[0106] In some embodiments, the first requested information is a first uplink MAC CE, where the first uplink MAC CE includes one or more MG IDs.

[0107] In an embodiment of the present disclosure, the terminal device receives positioning setting information of the network side device, and sends first request information to the network side device, requesting the network side device to indicate MG IDs corresponding to at least two carrier frequencies.

[0108] The first request information may be a first uplink MAC CE, where the first uplink MAC CE includes one or more MG IDs.

[0109] In some embodiments, the first uplink MAC CE further includes a carrier frequency to which the MG ID applies.

[0110] If the first request information is a first uplink MAC CE, the first uplink MAC CE includes one or more MG IDs, and the first uplink MAC CE further includes a carrier frequency to which the MG ID is applied, so that the terminal device can inform the network side device of which carrier frequency the requested MG ID is used to measure the positioning signal.

[0111] Exemplarily, a terminal device receives positioning configuration information of a network side device, where the positioning configuration information indicates two carrier frequency information of F1 and F2 of a positioning signal, and the terminal device sends first request information to the network side device and sends a first uplink MAC CE, where the first uplink MAC CE includes one MG ID, and the carrier frequencies to which the MG ID is applied are F1 and F2, thereby informing the network side device that the requested MG ID is used to measure the positioning signal at carrier frequencies F1 and F2.

[0112] In addition, the terminal device sends first request information to the network side device and sends a first uplink MAC CE, and the first uplink MAC CE further includes three MG IDs, where the carrier frequency to which the first MG ID is applied is F1, the carrier frequencies to which the second MG ID is applied are F1 and F2, and the carrier frequency to which the third MG ID is applied is F2, and the embodiments of the present disclosure are not specifically limited thereto.

[0113] S43, receiving MG setting information sent from a network side device, where the MG setting information includes one or more MG IDs and parameter information of MG corresponding to each MG ID.

[0114] In the embodiment of the present disclosure, the terminal device needs to receive the MG setting information sent from the network side device before sending the first request information to the network side device.

[0115] Here, the MG setting information includes one or more MG IDs and MG parameter information corresponding to each MG ID.

[0116] In an embodiment of the present disclosure, the network side device indicates at least two carrier frequency information of the positioning signal by sending positioning setting information to the terminal device, and before, after, or simultaneously sends MG setting information to the terminal device, the MG setting information including one or more MG IDs and parameter information of the MG corresponding to each MG ID; after receiving the above information sent from the network side device, the terminal device sends first request information to the network side device, and the first uplink MAC CE includes one or more MG IDs, thereby informing the network side device of the one or more MG IDs for measuring the positioning signal at the at least two carrier frequencies requested by the first uplink MAC CE.

[0117] For ease of understanding, the embodiments of the present disclosure provide exemplary examples.

[0118] Assuming that the terminal device receives MG setting information sent from the network side device, and the MG setting information includes three MG IDs, i.e., the first MG ID, the second MG ID, and the third MG ID, and MG parameter information corresponding to the first MG ID, the second MG ID, and the third MG ID, then receives the positioning setting information sent from the network side device, and indicates two carrier frequencies F1 and F2 of the positioning signal, and the terminal device can send first request information to the network side device after receiving the above information sent from the network side device. Assuming that the first uplink MAC CE includes one MG ID, i.e., the second MG ID, thereby notifying the network side device that the terminal device measures the positioning signal at two carrier frequencies F1 and F2 by requesting MG parameter information corresponding to the second MG ID.

[0119] Or, after receiving the above information sent from the network side device, the terminal device can send first request information to the network side device, assuming that the first uplink MAC CE includes two MG IDs, i.e., a second MG ID and a third MG ID, and the carrier frequency to which the second MG ID is applied is F1 and the carrier frequency to which the third MG ID is applied is F2, to inform the network side device that the terminal requests parameter information of the MG corresponding to the second MG ID to measure the positioning signal at the carrier frequency F1, and requests parameter information of the MG corresponding to the third MG ID to measure the positioning signal at the carrier frequency F2.

[0120] It should be noted that the above example is merely an example for helping to understand the present solution, and does not specifically limit the embodiments of the present disclosure. The positioning setting information of the network side device may include three or more carrier frequency information, the MG setting information sent from the network side device may further include three or more MG IDs, the first uplink MAC CE may include three or more MG IDs, etc.

[0121] In some embodiments, the parameter information of the MG includes at least one of a period, a slot offset value, and an interval duration length.

[0122] By way of example, the period may be 20 ms, or 40 ms, or 80 ms, or 160 ms, etc., and the gap duration may be 1 ms, 1.5 ms, 2 ms, 2.5 ms, 3 ms, 3.5 ms, 4 ms, 4.5 ms, 5 ms, 5.5 ms, 6 ms, etc.

[0123] The terminal device receives the positioning signal within a gap duration that occurs periodically, and can measure the positioning signal without receiving other downlink channels or signals transmitted from a network side device, such as a PDCCH (Physical Downlink Control Channel), a PDSCH (Physical Downlink Shared Channel), a CSI-RS (Channel State Information Reference Signal), a PBCH (Physical Broadcast Channel), or an SSB (synchronization signal block).

[0124] In some embodiments, when a set of MGs is applicable to at least two carrier frequencies, the positioning signals at the different carrier frequencies are measured within different interval durations, or the positioning signals at the different carrier frequencies are measured within the same interval duration.

[0125] Exemplarily, when one set of MGs is applied to two carrier frequencies F1 and F2, it can measure the positioning signal at F1 within the first interval duration, and measure the positioning signal at F2 within the second interval duration, or measure the positioning signals at F1 and F2 within the first interval duration. For example, when the period of this MG is 40 ms, the slot offset value is t0, and the gap duration is 6 ms, the first gap duration time is within t0 to t0 + 6 ms, and the second gap duration time is within t0 + 40 to t0 + 46 ms. The terminal device can measure the positioning signal at F1 within t0 to t0 + 6 ms, and measure the positioning signal at F2 within t0 + 40 to t0 + 46 ms. Or the terminal device can measure the positioning signals at F1 and F2 within t0 to t0 + 6 ms, for example, it can measure the positioning signal at F1 within t0 to t0 + 3 ms, and measure the positioning signal at F2 within t0 + 3 to t0 + 6 ms. Or the terminal device can measure the positioning signals at F1 and F2 within a time period from t0+40 to t0+46 ms, for example, measuring the positioning signal at F1 within a time period from t0+40 to t0+43 ms, and measuring the positioning signal at F2 within a time period from t0+43 to t0+46 ms.

[0126] Please refer to FIG. 5, which is a flowchart of another measurement time determining method provided by an embodiment of the present disclosure.

[0127] As shown in FIG. 5, the method is applied to a terminal device, and the method includes, but is not limited to, the following steps S51 to S52.

[0128] S51, receiving positioning setting information of a network side device, where the positioning setting information indicates at least two carrier frequency information of a positioning signal.

[0129] For the explanation related to S51 in the embodiment of the present disclosure, please refer to the relevant explanation in the above example, and similar explanation will be omitted here.

[0130] S52, receiving second indication information of a network side device, where the second indication information indicates one or more sets of processing windows, and the measurement time is the one or more sets of processing windows.

[0131] In addition, in an embodiment of the present disclosure, the terminal device receives second instruction information transmitted from the network side device, the second instruction information instructs one or more sets of processing windows, and the terminal device may use the same set of processing windows or may use multiple sets of processing windows when transmitting, receiving or measuring positioning signals of at least two carrier frequencies, or may use different processing windows when transmitting, receiving or measuring positioning signals of at least two carrier frequencies.

[0132] In some embodiments, the second indication information includes a third RRC, where the third RRC indicates parameter information for each set processing window.

[0133] In an embodiment of the present disclosure, the second indication information includes a third RRC, and indicates parameter information of each set processing window by the third RRC.

[0134] In addition, when the second instruction information indicates one set of processing windows, the third RRC indicates parameter information of the one set of processing windows, and when the second instruction information indicates multiple sets of processing windows, the third RRC indicates parameter information of each set of processing windows among the multiple sets of processing windows.

[0135] In some embodiments, the third RRC further indicates the carrier frequency to which each set processing window applies.

[0136] In addition, when the second instruction information indicates one set of processing windows, the third RRC further indicates a carrier frequency to which the one set of processing windows is to be applied, and when the second instruction information indicates multiple sets of processing windows, the third RRC further indicates a carrier frequency to which each of the multiple sets of processing windows is to be applied, where the carrier frequency to which each of the multiple sets of processing windows is to be applied may be the same or different.

[0137] In an embodiment of the present disclosure, the terminal device receives second indication information of the network side device, the second indication information includes a third RRC, the second indication information indicates one or multiple sets of processing windows, if the second indication information indicates one set of processing windows, the third RRC indicates parameter information of the one set of processing windows and carrier frequency to be applied, if the second indication information indicates multiple sets of processing windows, the third RRC indicates parameter information of each set of processing windows and carrier frequency to be applied, where the carrier frequency to which each set of processing windows is applied among the multiple sets of processing windows may be the same or different, so that the terminal device can determine the setting of the processing window that needs to be used to measure the positioning signal at the different carrier frequency according to the second indication information, and measure the positioning signal at the carrier frequency using the setting of the processing window.

[0138] Exemplarily, a terminal device receives positioning configuration information of a network side device, where the positioning configuration information indicates two carrier frequencies F1 and F2 of the positioning signal, and the terminal device receives second indication information of the network side device, where the second indication information includes a third RRC, where the third RRC indicates parameter information of two sets of processing windows and the carrier frequency to which each set processing window is applied, for example, the third RRC indicates parameter information of a first set of processing windows and the carrier frequency F1 to be applied, and indicates parameter information of a second set of processing windows and the carrier frequency F2 to be applied, so that the terminal device can determine which parameter information of the processing window the carrier frequency F1 and the carrier frequency F2 correspond to, and thus measure the positioning signal at the carrier frequency using the parameter information of the corresponding processing window.

[0139] Of course, in the above example, the third RRC can indicate parameter information of a set of processing windows and the carrier frequencies to which the set of processing windows is applied. Assuming that the third RRC indicates that the set of processing windows is applied to carrier frequencies F1 and F2, the terminal device can determine parameter information of the set of processing windows corresponding to carrier frequencies F1 and F2, respectively, and thus use the parameter information of the corresponding processing windows to measure the positioning signal at the carrier frequencies.

[0140] It should be noted that the above example is merely an example for helping to understand the present solution, and does not specifically limit the embodiments of the present disclosure. The positioning setting information of the network side device may include three or more carrier frequency information, etc.

[0141] In some embodiments, the second indication information includes a fourth RRC and a second MAC CE, where the fourth RRC sets multiple processing window IDs and parameter information of processing windows corresponding to each processing window ID, and the second MAC CE indicates one or more activated processing window IDs.

[0142] In an embodiment of the present disclosure, the second indication information includes a fourth RRC and a second MAC CE, where the fourth RRC sets multiple processing window IDs and parameter information of processing windows corresponding to each processing window ID, and the second MAC CE indicates one or more activated processing window IDs.

[0143] In an embodiment of the present disclosure, a terminal device receives second indication information sent from a network side device, the second indication information includes a fourth RRC and a second MAC CE, the fourth RRC sets a plurality of processing window IDs and parameter information of processing windows corresponding to each processing window ID, and the second MAC CE indicates one or more activated processing window IDs.

[0144] Here, when the second instruction information indicates one set of processing windows, the fourth RRC in the second instruction information may set multiple processing window IDs and parameter information of the processing windows corresponding to each processing window ID, whereas the second MAC CE in the second instruction information may indicate one activated processing window ID, so that the second instruction information indicates the parameter information of the processing window corresponding to the activated processing window ID and indicates the parameter information of one set of processing windows.

[0145] Here, when the second instruction information indicates multiple sets of processing windows, the fourth RRC in the second instruction information can set multiple processing window IDs and parameter information of the processing windows corresponding to each processing window ID, whereas the second MAC CE in the second instruction information can indicate multiple activated processing window IDs, so that the second instruction information indicates parameter information of the processing windows corresponding to the activated multiple processing window IDs and indicates parameter information of multiple sets of processing windows.

[0146] Exemplarily, when the second instruction information indicates a set of processing windows, the fourth RRC in the second instruction information may set three processing window IDs and parameter information of the processing windows corresponding to each processing window ID, whereas the second MAC CE in the second instruction information may indicate the activation of the second processing window ID among the three processing window IDs, thereby allowing the second instruction information to indicate the parameter information of a set of processing windows by indicating the parameter information of the processing window corresponding to the second processing window ID among the three activated processing window IDs.

[0147] Of course, the second instruction information can further indicate two sets of processing windows, and the fourth RRC in the second instruction information can set five processing window IDs and parameter information of the processing windows corresponding to each processing window ID, while the second MAC CE in the second instruction information can indicate the activation of the second and third processing window IDs among the five processing window IDs, so that the second instruction information can indicate parameter information of two sets of processing windows by indicating parameter information of the processing windows corresponding to the second and third processing window IDs among the activated five processing window IDs.

[0148] It should be noted that the above example is merely an example for helping to understand the present solution, and does not specifically limit the embodiments of the present disclosure. The second indication information may indicate three or more sets of processing windows, and the fourth RRC may set multiple processing window IDs, etc.

[0149] In some embodiments, the second MAC CE further indicates the carrier frequency to which each activated processing window ID applies.

[0150] In addition, when the second instruction information indicates one set of processing windows, the second MAC CE further indicates a carrier frequency to which one activated processing window ID is applied, and when the second instruction information indicates multiple sets of processing windows, the second MAC CE further indicates carrier frequencies to which multiple activated processing window IDs are applied, where the carrier frequencies to which each set of processing windows among the multiple sets of processing windows is applied may be the same or different.

[0151] In an embodiment of the present disclosure, a terminal device receives second instruction information from a network side device, where the second instruction information includes a fourth RRC, where the second instruction information indicates one set or multiple sets of processing windows, where if the second instruction information indicates one set of processing windows, the fourth RRC in the second instruction information can set multiple processing window IDs and parameter information of the processing windows corresponding to each processing window ID, whereby the second MAC CE in the second instruction information can indicate one activated processing window ID and a carrier frequency to which the activated processing window ID is applied, where if the second instruction information indicates multiple sets of processing windows, the fourth RRC in the second instruction information can set multiple processing window IDs and parameter information of the processing windows corresponding to each processing window ID, whereby the second MAC CE in the second instruction information can indicate multiple activated processing window IDs and carrier frequencies to which the activated processing window IDs are applied, whereby the carrier frequencies to which the multiple processing window IDs are applied may be the same or different. This enables the terminal device to determine, based on the second instruction information, the processing window setting that needs to be used to measure the positioning signal at the different carrier frequency, and then measures the positioning signal at the carrier frequency using the processing window setting.

[0152] Exemplarily, a terminal device receives positioning configuration information of a network side device, where the positioning configuration information indicates two carrier frequencies F1 and F2 of the positioning signal, and the terminal device receives second instruction information of the network side device, where the second instruction information includes a fourth RRC and a second MAC CE, where the fourth RRC can set five processing window IDs and parameter information of the processing windows corresponding to each processing window ID, and the second MAC CE can indicate the second and third processing window IDs of the five activated processing window IDs and the carrier frequencies to which the activated second and third processing window IDs are applied, for example, the second MAC CE indicates that the carrier frequency to which the second processing window ID is applied is carrier frequency F1, and indicates that the carrier frequency to which the third processing window ID is applied is carrier frequency F2, so that the terminal device can determine whether it needs to use the parameter information of the processing windows of the respective sets to measure carrier frequency F1 and carrier frequency F2, and thereby measure the positioning signal at the carrier frequency using the parameter information of the respective corresponding processing windows.

[0153] Of course, in the above example, the second MAC CE can indicate the carrier frequency F1 and carrier frequency F2 to which the activated one processing window ID is applied, so that the terminal device can determine the parameter information of the processing window corresponding to the activated one processing window ID that needs to be used respectively to measure the carrier frequency F1 and carrier frequency F2, so as to measure the positioning signal at the carrier frequency using the parameter information of the corresponding processing window respectively.

[0154] It should be noted that the above example is merely an example to help understand the present solution, and does not specifically limit the embodiments of the present disclosure. The positioning setting information of the network side device may include three or more carrier frequency information.

[0155] In some embodiments, the parameter information for the processing window includes at least one of a period, a starting slot value, a window duration length, and a priority of a signal located within the processing window.

[0156] In an embodiment of the present disclosure, the terminal device measures the positioning signals that it can receive and receive within a periodically occurring window duration based on the priority of the positioning signals.

[0157] For ease of understanding, an exemplary embodiment of the present disclosure provides an exemplary embodiment, in which a terminal device receives positioning setting information and second instruction information of a network side device, the positioning setting information indicates two carrier frequency information of the positioning signal, and the second instruction information includes a third RRC, and the third RRC indicates one or more sets of processing windows by indicating parameter information of each set processing window and a carrier frequency to which each set processing window is applied.

[0158] Here, the second indication information indicates parameter information of a set of processing windows and a carrier frequency to which the set of processing windows are applied, where the parameter information of the processing windows includes a period of 40 ms, a starting slot value of 2 ms, and a window duration length of 1 ms, and when the positioning signal has the highest priority, the terminal device can determine based on the second indication information that the parameter information of the processing windows corresponding to both of the two carrier frequencies of the positioning signal includes a period of 40 ms, a starting slot value of 2 ms, and a window duration length of 1 ms, so that the terminal device can receive and measure the positioning signal within a time period of 40 ms*N+2 to 40 ms*N+3 ms, where N is a non-negative integer.

[0159] In another exemplary embodiment, the terminal device receives positioning setting information and second instruction information of a network side device, the positioning setting information indicates two carrier frequency information of the positioning signal, the second instruction information includes a fourth RRC and a second MAC CE, the fourth RRC sets four processing window IDs and parameter information of the processing windows corresponding to each processing window ID, the second MAC CE instructs to activate the first and second processing window IDs of the four processing window IDs, and indicates two carrier frequencies of the positioning signal indicated by the positioning setting information corresponding to each of the activated first and second processing window IDs. Here, the parameter information of the processing window corresponding to the first activated processing window ID includes a period of 20 ms, a starting slot value of 2 ms, and a window duration of 1 ms, and the parameter information of the processing window corresponding to the second activated processing window ID includes a period of 40 ms, a starting slot value of 5 ms, and a window duration of 1.5 ms, and if the positioning signal has the highest priority, the terminal device can determine based on the second indication information that the parameter information of the processing window corresponding to one of the two carrier frequencies of the positioning signal includes a period of 20 ms, a starting slot value of 2 ms, and a window duration of 1 ms, and the parameter information of the processing window corresponding to the other carrier frequency includes a period of 40 ms, a starting slot value of 5 ms, and a window duration of 1.5 ms.

[0160] Thus, the terminal device can receive a positioning signal at one of the carrier frequencies and measure the positioning signal at the carrier frequency within a time period of 20ms*N+2~20ms*N+3ms, and can receive a positioning signal at the other carrier frequency and measure the positioning signal at the carrier frequency within a time period of 40ms*M+5~40ms*M+6.5ms, where M and N are non-negative integers.

[0161] Here, the priority is mainly compared with PDCCH / PDSCH / CSI-RS corresponding to non-URLLC (ultra-reliable low latency communication) and PDCCH / PDSCH / CSI-RS corresponding to URLLC.

[0162] For example, the priority of the positioning signal is higher than the above two types of PDCCH / PDSCH / CSI-RS, or the priority of the positioning signal is higher than the non-URLLC PDCCH / PDSCH / CSI-RS and lower than the URLLC PDCCH / PDSCH / CSI-RS, or the priority of the positioning signal is lower than the above two types of PDCCH / PDSCH / CSI-RS.

[0163] The PDCCH / PDSCH / CSI-RS corresponding to the URLLC is determined by the priority of the HARQ-ACK (hybrid automatic repeat request-acknowledgement) for the URLLC.

[0164] In some embodiments, when a set of processing windows is applicable to at least two carrier frequencies, the positioning signals are measured at different carrier frequencies within different window durations or the positioning signals are measured at different carrier frequencies within the same window duration.

[0165] Exemplarily, when one set of processing windows is applied to two carrier frequencies F1 and F2, the positioning signal at F1 can be measured within the first window duration, and the positioning signal at F2 can be measured within the second window duration, or the positioning signals at F1 and F2 can be measured within the first window duration. For example, when the period of the processing window is 40 ms, the starting slot value is t0, and the window duration is 6 ms, the first window duration is within the time t0 to t0 + 6 ms, and the second window duration is within the time t0 + 40 to t0 + 46 ms. The terminal device can measure the positioning signal at F1 within the time t0 to t0 + 6 ms, and measure the positioning signal at F2 from t0 + 40 to t0 + 46 ms. Or the terminal device can measure the positioning signals at F1 and F2 within the time t0 to t0 + 6 ms, for example, the positioning signal at F1 can be measured within the time t0 to t0 + 3 ms, and the positioning signal at F2 can be measured within the time t0 + 3 to t0 + 6 ms. Or the terminal device can measure the positioning signals at F1 and F2 within a time period from t0+40 to t0+46 ms, for example, measuring the positioning signal at F1 within a time period from t0+40 to t0+43 ms, and measuring the positioning signal at F2 within a time period from t0+43 to t0+46 ms.

[0166] Please refer to FIG. 6, which is a flowchart of another measurement time determining method provided by an embodiment of the present disclosure.

[0167] As shown in FIG. 6, the method is applied to a terminal device, and the method includes, but is not limited to, the following steps S61 to S63.

[0169] For the explanation related to S61 in the embodiment of the present disclosure, please refer to the relevant explanation in the above example, and similar explanation will be omitted here.

[0170] S62, second request information indicating a processing window request is sent to the network side device.

[0171] In an embodiment of the present disclosure, a terminal device receives positioning setting information of a network side device, and the positioning setting information indicates at least two carrier frequency information of a positioning signal, so that the terminal device determines that the at least two carrier frequency information is available for transmitting and receiving the positioning signal.

[0172] In this case, the terminal device can send second request information to the network side device, where the second request information indicates a processing window request, which can be understood as requesting the network side device to instruct the setting of a processing window.

[0173] In some embodiments, the second request information is a second uplink MAC CE, and the second uplink MAC CE includes one or more processing window IDs.

[0174] In an embodiment of the present disclosure, the terminal device receives positioning setting information of the network side device, and sends second request information to the network side device, requesting the network side device to instruct the setting of an MG corresponding to at least two carrier frequencies.

[0175] Here, the second request information may be a second uplink MAC CE, where the second uplink MAC CE includes one or more processing window IDs.

[0176] In some embodiments, the second uplink MAC CE further includes a carrier frequency to which the Processing Window ID applies.

[0177] If the second request information is a second uplink MAC CE, the second uplink MAC CE includes one or more processing window IDs, and the second uplink MAC CE further includes a carrier frequency to which the processing window ID is applied, so that the terminal device can inform the network side device of which carrier frequency the requested processing window ID is used to measure the positioning signal.

[0178] For example, a terminal device receives positioning setting information of a network side device, where the positioning setting information indicates two carrier frequency information of F1 and F2 of a positioning signal, and the terminal device sends second request information to the network side device and sends a second uplink MAC CE, where the second uplink MAC CE includes one processing window ID, and the carrier frequencies to which the processing window ID is applied are F1 and F2, thereby informing the network side device that the requested processing window ID is used to measure the positioning signal at carrier frequencies F1 and F2.

[0179] In addition, the terminal device sends second request information to the network side device and sends a second uplink MAC CE, and the second uplink MAC CE may further include three processing window IDs, where the carrier frequency to which the first processing window ID is applied is F1, the carrier frequencies to which the second processing window ID is applied are F1 and F2, and the carrier frequency to which the third processing window ID is applied is F2, and the embodiments of the present disclosure are not specifically limited thereto.

[0180] S63, receiving processing window setting information sent from a network side device, where the processing window setting information includes one or more processing window IDs and parameter information of the processing window corresponding to each processing window ID.

[0181] In the embodiment of the present disclosure, the terminal device needs to receive processing window setting information sent from the network side device before sending second request information to the network side device.

[0182] Here, the processing window setting information includes one or more processing window IDs, and parameter information of the processing window corresponding to each processing window ID.

[0183] In an embodiment of the present disclosure, the network side device sends positioning setting information to the terminal device to indicate at least two carrier frequency information of the positioning signal, and before, after, or simultaneously sends processing window setting information to the terminal device, the processing window setting information including one or more processing window IDs and parameter information of the processing window corresponding to each processing window ID; after receiving the above information sent from the network side device, the terminal device sends second request information to the network side device, and the second uplink MAC CE includes one or more processing window IDs, thereby informing the network side device of one or more processing window IDs for measuring the positioning signal at the at least two carrier frequencies requested by the second uplink MAC CE.

[0184] For ease of understanding, the embodiments of the present disclosure provide exemplary examples.

[0185] The terminal device receives processing window setting information sent from the network side device, and assuming that the processing window setting information includes three processing window IDs, namely, a first processing window ID, a second processing window ID, and a third processing window ID, and parameter information of the processing window corresponding to the first processing window ID, the second processing window ID, and the third processing window ID, the terminal device then receives the positioning setting information sent from the network side device, and indicates two carrier frequencies F1 and F2 of the positioning signal, and the terminal device can send second request information to the network side device after receiving the above information sent from the network side device. Assuming that the second uplink MAC CE includes one processing window ID, namely, the second processing window ID, the terminal informs the network side device that the terminal requests parameter information of the processing window corresponding to the second processing window ID to measure the positioning signal at the two carrier frequencies F1 and F2.

[0186] Or, after receiving the above information sent from the network side device, the terminal device can send second request information to the network side device, assuming that the second uplink MAC CE includes two processing window IDs, i.e., a second processing window ID and a third processing window ID, and the carrier frequency to which the second processing window ID is applied is F1, and the carrier frequency to which the third processing window ID is applied is F2, to inform the network side device that the terminal requests parameter information of the processing window corresponding to the second processing window ID to measure the positioning signal at the carrier frequency F1, and requests parameter information of the processing window corresponding to the third processing window ID to measure the positioning signal at the carrier frequency F2.

[0187] It should be noted that the above example is merely an example for helping to understand the present solution, and does not specifically limit the embodiments of the present disclosure. The positioning configuration information of the network side device may include three or more carrier frequency information, the MG configuration information sent from the network side device may further include three or more processing window IDs, and the first uplink MAC CE may further include three or more processing window IDs.

[0188] It should be noted that the above example is merely an example for helping to understand the present solution, and does not specifically limit the embodiments of the present disclosure. The positioning setting information of the network side device may include three or more carrier frequency information, the second uplink MAC CE may further include three or more processing window IDs, and the processing window setting information sent from the network side device may further include three or more processing window IDs.

[0189] In some embodiments, the parameter information for the processing window includes at least one of a period, a starting slot value, a window duration length, and a priority of a signal located within the processing window.

[0190] Illustratively, the period may be 20 ms, or 40 ms, or 80 ms, or 160 ms, etc., and the window duration may be 1 ms, 1.5 ms, 2 ms, 2.5 ms, 3 ms, 3.5 ms, 4 ms, 4.5 ms, 5 ms, 5.5 ms, 6 ms, etc.

[0191] In an embodiment of the present disclosure, the terminal device measures the positioning signals that it can receive and receive within a periodically occurring window duration based on the priority of the positioning signals.

[0192] Here, the priority is mainly compared between PDCCH / PDSCH / CSI-RS corresponding to non-URLLC and PDCCH / PDSCH / CSI-RS corresponding to URLLC.

[0193] For example, the priority of the positioning signal is higher than the above two types of PDCCH / PDSCH / CSI-RS, or the priority of the positioning signal is higher than the non-URLLC PDCCH / PDSCH / CSI-RS and lower than the URLLC PDCCH / PDSCH / CSI-RS, or the priority of the positioning signal is lower than the above two types of PDCCH / PDSCH / CSI-RS.

[0194] The PDCCH / PDSCH / CSI-RS corresponding to the URLLC is determined by the priority of the HARQ-ACK for the URLLC.

[0195] In some embodiments, when a set of processing windows is applicable to at least two carrier frequencies, the positioning signals are measured at different carrier frequencies within different window durations or the positioning signals are measured at different carrier frequencies within the same window duration.

[0196] Exemplarily, when one set of processing windows is applied to two carrier frequencies F1 and F2, the positioning signal at F1 can be measured within the first window duration, and the positioning signal at F2 can be measured within the second window duration, or the positioning signals at F1 and F2 can be measured within the first window duration. For example, when the period of the processing window is 40 ms, the starting slot value is t0, and the window duration is 6 ms, the first window duration is within the time t0 to t0 + 6 ms, and the second window duration is within the time t0 + 40 to t0 + 46 ms. The terminal device can measure the positioning signal at F1 within the time t0 to t0 + 6 ms, and measure the positioning signal at F2 from t0 + 40 to t0 + 46 ms. Or the terminal device can measure the positioning signals at F1 and F2 within the time t0 to t0 + 6 ms, for example, the positioning signal at F1 can be measured within the time t0 to t0 + 3 ms, and the positioning signal at F2 can be measured within the time t0 + 3 to t0 + 6 ms. Or the terminal device can measure the positioning signals at F1 and F2 within a time period from t0+40 to t0+46 ms, for example, measuring the positioning signal at F1 within a time period from t0+40 to t0+43 ms, and measuring the positioning signal at F2 within a time period from t0+43 to t0+46 ms.

[0197] Please refer to FIG. 7, which is a flowchart of another measurement time determining method provided by an embodiment of the present disclosure.

[0198] As shown in FIG. 7, the method is applied to a network side device, and the method may include, but is not limited to, the following steps S71 to S72.

[0199] S71, sending positioning setting information to a terminal device, where the positioning setting information indicates at least two carrier frequency information of a positioning signal.

[0200] In an embodiment of the present disclosure, a terminal device receives positioning setting information of a network side device, and the positioning setting information indicates at least two carrier frequency information of a positioning signal, so that the terminal device determines that the at least two carrier frequency information is available for transmitting and receiving the positioning signal.

[0201] In some embodiments, the positioning signal includes a Positioning Reference Signal (PRS) or other positioning signal.

[0202] Of course, in the embodiments of the present disclosure, the positioning signal may be other signals than PRS, and may be other new positioning signals as technology continues to advance, and the embodiments of the present disclosure are not specifically limited thereto.

[0203] In some embodiments, the network side device includes at least one of a core network device and an access network device.

[0204] The core network device in the embodiment of the present disclosure may include a location management function network element. Optionally, the location management function network element includes a location server, which may be realized as any one of a Location Management Function (LMF), an Enhanced Serving Mobile Location Centre (E-SMLC), a Secure User Plane Location (SUPL), and a SUPL Location Platform (SUPL SLP).

[0205] S72, sending a measurement time setting parameter to the terminal device, where the measurement time setting parameter indicates a measurement time of the positioning signal.

[0206] In an embodiment of the present disclosure, a terminal device receives positioning setting information transmitted from a network side device, obtains at least two carrier frequency information usable for transmitting and receiving a positioning signal, and based on this, receives a measurement time setting parameter transmitted from the network side device, and when the measurement time setting parameter indicates a measurement time of the positioning signal, determines that at least two carrier frequency information are usable for transmitting and receiving the positioning signal and the measurement time for measuring the positioning signal. Thus, the terminal device can measure positioning signals of multiple carrier frequencies within a specified time range of the measurement time, and the accuracy of positioning can be improved.

[0207] In some embodiments, the positioning signals are used in a carrier phase based positioning method.

[0208] Here, in the carrier phase-based positioning method, the contents to be measured and reported include the fractional part and the number of revolutions of the carrier phase. The fractional part of the carrier phase refers to a fractional part less than one revolution, and is the part of the difference between the phase of a reference signal generated by the receiving side (terminal device or network side device) and the phase of a carrier signal from a transmitting point (network side device or terminal device) that is less than one revolution, or the part of the phase of a carrier signal from a transmitting point received by the receiving side that is less than one revolution. The number of revolutions corresponds to the number of revolutions that is less than one revolution.

[0209] In addition, the network side device transmits positioning setting information to the terminal device, and the positioning setting information indicates at least two carrier frequency information of the positioning signal, and the network side device transmits a measurement time setting parameter to the terminal device, thereby indicating the measurement time of the positioning signal at the at least two carrier frequencies.

[0210] When the positioning signals of at least two carrier frequencies are transmitted simultaneously, the at least two carrier frequencies may be set to the measurement interval MG simultaneously, or the at least two carrier frequencies may be set to the processing window simultaneously.

[0211] In some embodiments, when positioning signals of at least two carrier frequencies are transmitted at different times, one carrier frequency of the at least two carrier frequencies may be set to the measurement interval MG, and the other carrier frequency of the at least two carrier frequencies may be set to the processing window.

[0212] For example, when the positioning signals of two carrier frequencies are transmitted at different times, one of the two carrier frequencies may be set to the measurement interval MG, and the other of the two carrier frequencies may be set to the processing window. In the embodiment of the present disclosure, the positioning signal is measured by a carrier phase-based positioning method, and when it is determined that at least two carrier frequency information is available for the positioning signal and the measurement time of measuring the positioning signal, because the wavelengths of the multiple carrier frequencies are different but the transmission distances through which they pass are the same, the measurement of the positioning signals of at least two carrier frequencies can improve the measurement accuracy of the positioning.
