[0039] The access device 12 may be a network-side device in a wireless communication system.

[0042] As shown in FIG2A , an embodiment of the present disclosure provides an information processing method, which is performed by a core network device, wherein the method further includes:

[0043] S1110: Send indication information to the access network device, where the indication information indicates bandwidth aggregation of positioning reference signals.

[0044] The core network device may be any core network function that performs positioning management. This positioning management may include absolute positioning and / or relative positioning management. Exemplarily, positioning management includes calculating the UE's position, providing positioning assistance information, obtaining positioning measurement results, and sending positioning requests. Exemplarily, the core network device may include, but is not limited to, a Location Management Function (LMF).

[0045] The access network equipment may include: eNB, gNB and / or Transmission and Receiving Point (TRP).

[0046] The indication information indicates that bandwidth aggregation should be performed on the positioning reference signal, and the access network device configures the positioning reference signal to achieve bandwidth aggregation. The positioning reference signal may include: an uplink positioning reference signal and / or a downlink positioning reference signal.

[0047] Here, instructing the positioning reference signals to perform bandwidth aggregation is equivalent to the terminal needing to send positioning reference signals of different frequencies and / or receive positioning reference signals of different frequencies when performing positioning measurement.

[0048] This bandwidth aggregation may include: aggregation across frequency bands, aggregation across carriers, and aggregation across bandwidth parts (Band Width Part, BWP).

[0049] The bandwidth-aggregated positioning reference signals need to meet specified conditions before the terminal can perform bandwidth aggregation on the positioning reference signals and / or the access network device can perform bandwidth aggregation on the positioning reference signals.

[0050] The specified conditions may include: some parameters of any two or three positioning reference signals that need to be bandwidth aggregated need to be the same, and the parameters involve the configuration of the positioning reference signals. By sending the indication information, the access network device can be instructed to perform the corresponding positioning reference signal configuration.

[0051] In some embodiments, the positioning reference signal includes at least one of the following:

[0052] Downlink positioning reference signal PRS;

[0053] Uplink sounding reference signal SRS.

[0054] In some embodiments, the indication information includes at least one of the following:

[0055] A first frequency band indication, indicating a frequency layer and / or carrier for bandwidth aggregation of a reference signal to be positioned;

[0056] A first frequency band combination indication, indicating a frequency layer combination and / or carrier combination capable of locating a reference signal bandwidth aggregation;

[0057] The first priority information indicates the priority corresponding to the frequency layer combination or carrier combination.

[0058] Exemplarily, bandwidth aggregation of multiple PRSs of different frequencies is performed on a frequency layer indicated by the first frequency band indicator, or bandwidth aggregation is performed on PRSs on multiple frequency layers indicated by the first frequency indicator. Furthermore, exemplary, bandwidth aggregation of multiple SRSs of different subcarriers is performed on a carrier indicated by the first frequency band indicator, or bandwidth aggregation is performed on SRSs on multiple carriers indicated by the first frequency band indicator.

[0059] The first frequency band combination indicates a frequency band layer combination or a carrier combination involved. A frequency band layer combination may include at least two frequency band layers, with different frequency band layers corresponding to different frequencies. A carrier combination may include multiple carriers, with different carriers having different frequencies.

[0060] Exemplarily, bandwidth aggregation is performed on PRSs of part or all of the frequency layers indicated by the first frequency combination indication.

[0061] As another example, bandwidth aggregation is performed on the SRSs of some or all of the carriers indicated by the first frequency combination indication.

[0062] The first priority information indicates a priority. Different frequency layer combinations and / or carrier combinations have priorities.

[0063] The first priority information instructs the LMF to determine the frequency layer combination and / or carrier combination for priority use of bandwidth aggregation. In this way, the access network device preferentially selects the frequency layer combination and / or carrier combination with a high priority for bandwidth aggregation of PRS and / or SRS based on the first priority information.

[0064] Exemplarily, the first priority information is set based on the frequency intervals between multiple frequency layers involved in the frequency layer combination, or based on the frequency intervals between different carriers in the carrier combination. For example, if the frequency interval between any two frequency layers in the frequency layer combination is negatively correlated with the priority level, the bandwidth requirement supported by the antenna of the access network device and / or terminal can be reduced.

[0065] As another example, the first priority information may be determined based on historical positioning information for each frequency layer combination and / or carrier combination. For example, the first priority information may be determined based on historical positioning accuracy, with higher historical positioning accuracy indicating a higher priority. Another example may be based on the signal quality of a positioning reference signal for a corresponding frequency layer combination or carrier combination. For example, higher signal quality indicates a higher priority. Of course, the above is merely an example of generating the first priority information, and specific implementations are not limited to these examples.

[0066] Exemplarily, the indication information for the PRS includes one of the following:

[0067] The first frequency band indication indicates the frequency layering of the PRS of the reference signal bandwidth aggregation to be positioned;

[0068] The first frequency band combination indication indicates a frequency layered combination of PRSs capable of positioning reference signal bandwidth aggregation;

[0069] The first priority information indicates the priority of the PRS frequency layer combination.

[0070] Exemplarily, the indication information for the SRS includes one of the following:

[0071] The first frequency band indication indicates a carrier of an SRS of a bandwidth-aggregated reference signal to be located;

[0072] The first frequency band combination indication indicates a carrier combination capable of positioning an SRS of a reference signal bandwidth aggregation;

[0073] The first priority information indicates the priority of the SRS carrier combination.

[0074] Exemplarily, the indication information is carried in a New Radio Positioning Protocol type a (NRPPa) message.

[0075] The NRPPa message may use NRPPa communication messages, where NRPPa is a dedicated protocol for positioning-related communications between the LMF and the base station.

[0076] Exemplarily, the NRPPa message is a positioning information request message.

[0077] In some embodiments, the positioning information request message may be a message from the LMF instructing the access network device to perform positioning. Using the positioning information request message to carry the indication information eliminates the need for a dedicated message to carry the indication information, reduces the construction of new messages, and enhances compatibility with related technologies.

[0078] In some embodiments, the indication information may also be sent from the LMF to the access network device via a dedicated NRPPa message.

[0079] As shown in FIG2B , an embodiment of the present disclosure provides an information processing method, which is performed by a core network device, wherein the method further includes:

[0080] S1210: Receive auxiliary information of the terminal.

[0081] Exemplarily, the auxiliary information may be used by the terminal to request bandwidth aggregation of positioning reference signals.

[0082] As another example, the auxiliary information can be used by the LMF to determine whether to indicate bandwidth aggregation of positioning reference signals and / or how to perform bandwidth aggregation of positioning reference signals. That is, the auxiliary information can be used by the LMF to determine the aforementioned indication information.

[0083] In some embodiments, after receiving the auxiliary information, the core network device such as LMF can send indication information with reference to the auxiliary information.

[0084] In other embodiments, after receiving the auxiliary information, the core network device such as LMF may send the indication information without referring to the auxiliary information.

[0085] Exemplarily, the auxiliary information may be recommendation information for bandwidth aggregation of positioning reference signals provided by the terminal to the LMF based on its own terminal capabilities and / or positioning requirements.

[0086] In some other embodiments, the auxiliary information includes at least one of the following:

[0087] A second frequency band indication, indicating that the terminal expects or supports frequency layers and / or carriers for positioning reference signal bandwidth aggregation;

[0088] A second frequency band combination indication, indicating that the terminal expects or supports a frequency layer combination and / or carrier combination of positioning reference signal bandwidth aggregation;

[0089] The second priority information indicates the priority of the frequency layer combination and / or carrier combination.

[0090] The terminal's needs can be known by receiving auxiliary information related to the frequency layer and / or carrier of the positioning reference signal bandwidth aggregation desired by the terminal, or the frequency layer combination and / or carrier combination of the desired positioning reference signal bandwidth aggregation.

[0091] The terminal's capabilities can be known by receiving auxiliary information related to the frequency layers and / or carriers of the positioning reference signal bandwidth aggregation supported by the terminal, or the frequency layer combinations and / or carrier combinations of the positioning reference signal bandwidth aggregation supported by the terminal.

[0092] Exemplarily, the second frequency band indication will indicate that the terminal supports or expects bandwidth aggregation of PRSs of multiple different frequencies on one frequency layer, or the second frequency indication will indicate that the terminal supports or expects bandwidth aggregation of PRSs on multiple frequency layers. Also exemplarily, the second frequency band indication will indicate that the terminal supports or expects bandwidth aggregation of SRSs of multiple different subcarriers on one carrier, or the second frequency indication will indicate that the terminal supports or expects bandwidth aggregation of SRSs on multiple carrier layers.

[0093] The second frequency band combination indicates a frequency band layer combination or a carrier combination involved. A frequency band layer combination may include at least two frequency band layers, with different frequency band layers corresponding to different frequencies. A carrier combination may include multiple carriers, with different carriers having different frequencies.

[0094] Exemplarily, bandwidth aggregation is performed on PRSs of part or all of the frequency layers indicated by the second frequency combination indication.

[0095] As another example, bandwidth aggregation is performed on the SRSs of some or all of the carriers indicated by the second frequency combination indication.

[0096] The second priority information indicates a priority. Different frequency layer combinations and / or carrier combinations have priorities.

[0097] The second priority information indicates that the terminal desires to prioritize the use of frequency layer combinations and / or carrier combinations for bandwidth aggregation. In this way, core network devices such as LMF can generate indication information based on the auxiliary information. For example, the first priority information is generated based on the second priority information.

[0098] Exemplarily, the second priority information is set based on the frequency intervals between multiple frequency layers involved in the frequency layer combination, or based on the frequency intervals between different carriers in the carrier combination. For example, if the frequency interval between any two frequency layers in the frequency layer combination is negatively correlated with the priority level, the bandwidth requirement supported by the antenna of the access network device and / or terminal can be reduced.

[0099] As another example, the second priority information can be determined based on historical positioning information for each frequency layer and / or carrier combination. For example, the second priority information can be determined based on historical positioning accuracy, with higher historical positioning accuracy indicating a higher priority. Another example is the second priority information can be determined based on the signal quality of the positioning reference signal for the corresponding frequency layer combination or carrier combination. For example, higher signal quality indicates a higher priority. Of course, the above is merely an example of generating the second priority information, and specific implementations are not limited to these examples.

[0100] In some embodiments, the assistance information includes a Long Term Evolution Positioning Protocol (LPP) assistance request message.

[0101] In some embodiments, the indication information includes:

[0102] Frequency band number;

[0103] offset and / or bandwidth relative to a reference frequency value;

[0104] The identifier of the partial bandwidth BWP.

[0105] The frequency band number may be various frequency band numbers, for example, N49, N97 or N48, etc., which are frequency band numbers for distinguishing different frequency bands.

[0106] The reference frequency value may include point (Point) A and / or point (Point) B when frequency resources are rasterized.

[0107] Different offset values ​​relative to the same reference frequency value indicate different frequency band layers and / or carriers.

[0108] In some embodiments, the offset values ​​and bandwidths relative to the same reference frequency value are different, and the frequency layers and / or center frequencies and bandwidths specifically pointed to are different.

[0109] The system frequency band resources can be divided into one or more BWPs, each of which has its own identifier, including but not limited to a BWP number.

[0110] One or more of the frequency band number, offset value, and / or bandwidth, and BWP identifier may be used as a component of the aforementioned first frequency band indication and / or first frequency band indication combination. Of course, one or more of the frequency band number, offset value, and / or bandwidth, and BWP identifier may be used as a component of the second frequency band indication and / or second frequency band indication combination.

[0111] As shown in FIG3A , an embodiment of the present disclosure provides an information processing method, which is performed by an access network device. The method includes:

[0112] S2110: Receive indication information, where the indication information indicates bandwidth aggregation of positioning reference signals.

[0113] The access network device can be a base station, TRP, CU and / or DU, etc.

[0114] In an embodiment of the present disclosure, the access network device receives indication information from the core network device, for example, receives indication information from the LMF.

[0115] The indication information may indicate bandwidth aggregation of SRS and / or bandwidth aggregation of PRS.

[0116] As shown in FIG3B , an embodiment of the present disclosure provides an information processing method, which is performed by an access network device. The method includes:

[0117] S2210: Receive indication information, where the indication information indicates bandwidth aggregation of positioning reference signals.

[0118] S2220: Determine the positioning reference signal configuration according to the indication information.

[0119] The reference signal configuration may include an SRS configuration and / or a PRS configuration.

[0120] Exemplarily, determining the positioning reference signal configuration according to the indication information may include: when the indication information indicates positioning reference signal bandwidth aggregation, determining the positioning reference signal configuration according to a condition that the positioning reference signal bandwidth aggregation needs to meet.

[0121] Conditions that need to be met for bandwidth aggregation of positioning reference signals may include: at least some parameters of any two positioning reference signals that can be bandwidth aggregated must be the same.

[0122] For PRS, the same parameters of two or three positioning reference signals that require bandwidth aggregation may include, but are not limited to, at least one of the following:

[0123] Antenna port;

[0124] Period and offset (periodicity and offset), illustratively, the period and offset are mainly for periodic PRS and / or semi-persistent PRS;

[0125] Muting pattern: a pattern in which no PRS is sent;

[0126] Number of PRS resource sets;

[0127] Number of PRS resources;

[0128] An offset value, for example, an NR-DL-PRS-SFN0-Offset value, where the NR-DL-PRS-SFN0-Offset value is the offset of the time domain position of the PRS relative to system frame #0 and timeslot #0;

[0129] A PRS pattern, which may be a frequency pattern for a PRS on the same time domain resource, may be used to determine the time-frequency domain resource for transmitting the PRS.

[0130] For SRS, the same parameters of two or three positioning reference signals that require bandwidth aggregation may include, but are not limited to, at least one of the following:

[0131] Timing Advance (TA) or Timing Advance Group (TAG);

[0132] Periodicity and offset (Periodicity And Offset), illustratively, the periodicity and offset are mainly for periodic SRS and / or semi-persistent SRS;

[0133] Slot Offset: The number of time slots between the downlink control information (DCI) that triggers the positioning reference signal and the SRS resource set (Resource Set); this slot offset can be mainly used for aperiodic SRS. The aperiodic SRS may include dynamically scheduled SRS;

[0134] SRS resource set;

[0135] Same number of SRSs;

[0136] Path loss configuration;

[0137] Determine a parameter of each subcarrier power, which may include P0 and / or α in the calculation formula;

[0138] Antenna port;

[0139] The SRS pattern may be a frequency pattern for the SRS on the same time domain resource. The SRS pattern may be used to determine the time-frequency domain resource for transmitting the SRS.

[0140] In this way, LMF can indicate the access network device indication information based on the terminal capabilities and / or positioning requirements, etc., to facilitate the determination of whether bandwidth aggregation is to be performed when configuring the positioning reference signal, thereby making full use of terminals with different capabilities for positioning measurements and / or meeting different positioning requirements.

[0141] For example, if the LMF needs to perform positioning measurements at a first level of accuracy on a terminal, it may send an indication to the access network device and instruct it to perform positioning measurements on positioning reference signals. For another example, if the LMF needs to perform positioning measurements at a second level of accuracy on a terminal, and the second level of accuracy can be achieved without bandwidth aggregation, it may not send the indication to the access network device. In this way, upon not receiving the indication, the access network device will not perform positioning reference signal configuration related to bandwidth aggregation for the positioning reference signal.

[0142] Exemplarily, the positioning reference signal includes at least one of the following:

[0143] Downlink positioning reference signal PRS;

[0144] Uplink sounding reference signal SRS.

[0145] In some embodiments, the indication information includes at least one of the following:

[0146] A first frequency band indication, indicating a frequency layer and / or carrier for bandwidth aggregation of a reference signal to be positioned;

[0147] A first frequency band combination indication, indicating a frequency layer combination and / or carrier combination capable of locating a reference signal bandwidth aggregation;

[0148] The first priority information indicates the priority corresponding to the frequency layer combination or carrier combination.

[0149] Exemplarily, bandwidth aggregation of multiple PRSs of different frequencies is performed on a frequency layer indicated by the first frequency band indication, or bandwidth aggregation is performed on PRSs on multiple frequency layers indicated by the first frequency indication. Furthermore, exemplary, bandwidth aggregation of multiple SRSs of different subcarriers is performed on a carrier indicated by the first frequency band indication, or bandwidth aggregation is performed on SRSs on multiple carrier layers indicated by the first frequency indication.

[0150] The first frequency band combination indicates a frequency band layer combination or a carrier combination involved. A frequency band layer combination may include at least two frequency band layers, with different frequency band layers corresponding to different frequencies. A carrier combination may include multiple carriers, with different carriers having different frequencies.

[0151] Exemplarily, bandwidth aggregation is performed on PRSs of part or all of the frequency layers indicated by the first frequency combination indication.

[0152] As another example, bandwidth aggregation is performed on the SRSs of some or all of the carriers indicated by the first frequency combination indication.

[0153] The first priority information indicates a priority. Different frequency layer combinations and / or carrier combinations have priorities.

[0154] The first priority information instructs the LMF to determine the frequency layer combination and / or carrier combination for priority use of bandwidth aggregation. In this way, the access network device preferentially selects the frequency layer combination and / or carrier combination with a high priority for bandwidth aggregation of PRS and / or SRS based on the first priority information.

[0155] Exemplarily, the first priority information is set based on the frequency intervals between multiple frequency layers involved in the frequency layer combination, or based on the frequency intervals between different carriers in the carrier combination. For example, if the frequency interval between any two frequency layers in the frequency layer combination is negatively correlated with the priority level, the bandwidth requirement supported by the antenna of the access network device and / or terminal can be reduced.

[0156] As another example, the first priority information may be determined based on historical positioning information for each frequency layer and / or carrier combination. For example, the first priority information may be determined based on historical positioning accuracy, with higher historical positioning accuracy indicating a higher priority. Another example may be based on the signal quality of a positioning reference signal at a corresponding frequency layer combination or carrier combination. For example, higher signal quality indicates a higher priority. Of course, the above is merely an example of generating the first priority information, and specific implementations are not limited to these examples.

[0157] In some embodiments, the indication information for the PRS includes one of the following:

[0158] The first frequency band indication indicates the frequency layering of the PRS of the reference signal bandwidth aggregation to be positioned;

[0159] The first frequency band combination indication indicates a frequency layered combination of PRSs capable of positioning reference signal bandwidth aggregation;

[0160] The first priority information indicates the priority of the PRS frequency layer combination.

[0161] In some embodiments, the indication information for the SRS includes one of the following:

[0162] The first frequency band indication indicates a carrier of an SRS of a bandwidth-aggregated reference signal to be located;

[0163] The first frequency band combination indication indicates a carrier combination capable of positioning an SRS of a reference signal bandwidth aggregation;

[0164] The first priority information indicates the priority of the SRS carrier combination.

[0165] Exemplarily, the indication information is carried in a New Radio Positioning Protocol type NRPPa message.

[0166] The NRPPa message may use NRPPa communication messages, where NRPPa is a dedicated protocol for positioning-related communications between the LMF and the base station.

[0167] Exemplarily, the NRPPa message is a positioning information request message.

[0168] Exemplarily, the instruction information includes:

[0169] Frequency band number;

[0170] offset and / or bandwidth relative to a reference frequency value;

[0171] The identifier of the partial bandwidth BWP.

[0172] The frequency band number may be various frequency band numbers, for example, N49, N97 or N48, etc., which are frequency band numbers for distinguishing different frequency bands.

[0173] The reference frequency value may include point (Point) A and / or point (Point) B when frequency resources are rasterized.

[0174] Different offset values ​​relative to the same reference frequency value indicate different frequency band layers and / or carriers.

[0175] In some embodiments, the offset values ​​and bandwidths relative to the same reference frequency value are different, and the frequency layers and / or center frequencies and bandwidths specifically pointed to are different.

[0176] The system frequency band resources can be divided into one or more BWPs, each of which has its own identifier, including but not limited to a BWP number.

[0177] One or more of the frequency band number, offset value, and / or bandwidth, and BWP identifier may be components of the aforementioned first frequency band indication and / or frequency band indication combination. Of course, one or more of the frequency band number, offset value, and / or bandwidth, and BWP identifier may be components of the second frequency band indication and / or frequency band indication combination.

[0178] As shown in FIG4A , an embodiment of the present disclosure provides an information processing method, which is executed by a terminal. The method includes:

[0179] S3110: Send auxiliary information; wherein, the auxiliary information is used for the core network device to generate indication information; wherein, the indication information indicates bandwidth aggregation of the positioning reference signal.

[0180] The terminal may be any type of communication device. The terminal may include a fixed terminal and / or a mobile terminal. The mobile terminal includes, but is not limited to, a mobile phone, a tablet computer, a wearable device, a smart home device, a smart office device, a vehicle-mounted device, and / or an aircraft device.

[0181] The positioning reference signal may include, but is not limited to, an SRS and / or a PRS.

[0182] Exemplarily, the terminal sends the auxiliary information to the core network device. For example, the terminal sends the auxiliary information to the LMF.

[0183] Exemplarily, the auxiliary information may be carried in an LPP message and sent to the core network device. Furthermore, the LPP message may include but is not limited to LPP auxiliary data.

[0184] For example, when performing access registration and / or registration update, the terminal sends a registration request and / or registration update request carrying the auxiliary information to the core network device. This not only enables the terminal to provide the core network device with the auxiliary information for determining the indication information, but also carries the auxiliary information in the registration request and / or registration update request, which is equivalent to multiplexing the registration request and / or registration update request message, thereby achieving simplified information transmission.

[0185] As shown in FIG4B , an embodiment of the present disclosure provides an information processing method, which is executed by a terminal. The method includes:

[0186] S3210: Receive a positioning reference signal configuration, where the positioning reference signal configuration may be an SRS configuration and / or a PRS configuration.

[0187] The positioning reference signal configuration indicates whether to perform bandwidth aggregation of positioning reference signals or not to perform bandwidth aggregation of positioning reference signals.

[0188] Exemplarily, the positioning reference signal configuration may be generated based on indication information, which in turn is generated based on auxiliary information.

[0189] In some embodiments, the auxiliary information includes at least one of the following:

[0190] A second frequency band indication, indicating that the terminal expects or supports frequency layers and / or carriers for positioning reference signal bandwidth aggregation;

[0191] A second frequency band combination indication, indicating that the terminal expects or supports a frequency layer combination and / or carrier combination of positioning reference signal bandwidth aggregation;

[0192] The second priority information indicates the priority of the frequency layer combination and / or carrier combination.

[0193] The terminal's needs can be known by receiving auxiliary information related to the frequency layer and / or carrier of the positioning reference signal bandwidth aggregation desired by the terminal, or the frequency layer combination and / or carrier combination of the desired positioning reference signal bandwidth aggregation.

[0194] The terminal's capabilities can be known by receiving auxiliary information related to the frequency layers and / or carriers of the positioning reference signal bandwidth aggregation supported by the terminal, or the frequency layer combinations and / or carrier combinations of the positioning reference signal bandwidth aggregation supported by the terminal.

[0195] Exemplarily, the second frequency band indication will indicate that the terminal supports or expects bandwidth aggregation of PRSs of multiple different frequencies on one frequency layer, or the second frequency indication will indicate that the terminal supports or expects bandwidth aggregation of PRSs on multiple frequency layers. Also exemplarily, the second frequency band indication will indicate that the terminal supports or expects bandwidth aggregation of SRSs of multiple different subcarriers on one carrier, or the second frequency indication will indicate that the terminal supports or expects bandwidth aggregation of SRSs on multiple carrier layers.

[0196] The second frequency band combination indicates a frequency band layer combination or a carrier combination involved. A frequency band layer combination may include at least two frequency band layers, with different frequency band layers corresponding to different frequencies. A carrier combination may include multiple carriers, with different carriers having different frequencies.

[0197] Exemplarily, bandwidth aggregation is performed on PRSs of part or all of the frequency layers indicated by the second frequency combination indication.

[0198] As another example, bandwidth aggregation is performed on the SRSs of some or all of the carriers indicated by the second frequency combination indication.

[0199] The second priority information indicates a priority. Different frequency layer combinations and / or carrier combinations have priorities.

[0200] The second priority information indicates that the terminal desires to prioritize the use of frequency layer combinations and / or carrier combinations for bandwidth aggregation. In this way, core network devices such as LMF can generate indication information based on the auxiliary information. For example, the first priority information is generated based on the second priority information.

[0201] Exemplarily, the second priority information is set based on the frequency intervals between multiple frequency layers involved in the frequency layer combination, or based on the frequency intervals between different carriers in the carrier combination. For example, if the frequency interval between any two frequency layers in the frequency layer combination is negatively correlated with the priority level, the bandwidth requirement supported by the antenna of the access network device and / or terminal can be reduced.

[0202] As another example, the second priority information can be determined based on historical positioning information for each frequency layer and / or carrier combination. For example, the second priority information can be determined based on historical positioning accuracy, with higher historical positioning accuracy indicating a higher priority. Another example is the second priority information can be determined based on the signal quality of the positioning reference signal for the corresponding frequency layer combination or carrier combination. For example, higher signal quality indicates a higher priority. Of course, the above is merely an example of generating the second priority information, and specific implementations are not limited to these examples.

[0203] For PRS bandwidth aggregation and SRS bandwidth aggregation, there are some requirements for PRS configurations of different frequency layers (PRS Frequency Layer, PFL) and SRS configurations of different carriers participating in bandwidth aggregation.

[0204] For example, the SRS requires the same periodicity, offset, and slot offset; the PRS requires the same periodicity, slot offset, and muting pattern. Therefore, based on the process where the LMF instructs the gNB to configure PRS or SRS, the PRS or SRS configuration determined by the gNB may not meet the conditions for bandwidth aggregation, and thus bandwidth aggregation of the PRS or SRS cannot be performed.

[0205] When the LMF requests PRS configuration from the gNB / TRP, it includes PRS bandwidth aggregation indication information. This indication information may be referred to as an indication. The indication information includes:

[0206] Frequency layer indication of bandwidth aggregation;

[0207] If the indication information includes multiple frequency layer combinations of bandwidth aggregation, indicate the priority of each combination;

[0208] The indication is contained in the NRPPa message.

[0209] The NRPPa message may include but is not limited to a TRP request (TRP information request) and / or a PRS configuration request (PRS configuration request).

[0210] When the LMF requests SRS configuration from the gNB / TRP, it includes indication information for SRS bandwidth aggregation. This indication information may be referred to as an indication. The indication information includes:

[0211] Bandwidth aggregation carrier indication;

[0212] If multiple carrier combinations with bandwidth aggregation are included, indicate the priority of each combination.

[0213] The indication is included in: an NRPPa message, which may include a positioning information request.

[0214] The LMF sends positioning reference signal bandwidth aggregation indication information to the gNB / TRP, where the indication information includes:

[0215] Downlink Positioning Reference Signal (PRS) bandwidth aggregation indication;

[0216] Uplink Positioning Reference Signal (SRS) bandwidth aggregation indicator.

[0217] The downlink positioning reference signal (PRS) bandwidth aggregation indication includes one of the following:

[0218] Frequency layer indication of bandwidth aggregation, for example, requesting PRS of f1 and f2 for bandwidth aggregation;

[0219] If multiple frequency layer combinations with bandwidth aggregation are included, indicate the priority of each combination; for example, {f1,f2},{f1,f3},{f1,f2,f3};

[0220] TRP indication, where the TRP indication indicates bandwidth aggregation of PRS resources of multiple frequency layers of the TRP.

[0221] LMF through NRPPa message: TRP information request and / or PRS configuration request

[0222] The UE sends the downlink positioning bandwidth aggregation request by requesting assistance data via LPP.

[0223] The uplink positioning reference signal (SRS) bandwidth aggregation indication includes one of the following:

[0224] Carrier indication for bandwidth aggregation, such as requesting f1 and f2 to perform bandwidth aggregation;

[0225] If multiple bandwidth aggregated carrier combinations are included, indicate the priority of each combination; for example, {f1,f2},{f1,f3},{f1,f2,f3};

[0226] The indication is sent via the Positioning information request in the NRPPa message.
