[0028] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0029] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the present disclosure. The singular forms “a” and “the” as used in this disclosure and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

[0030] It should be understood that although the terms first, second, third, etc., may be used to describe various information in embodiments of this disclosure, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, first information may also be referred to as second information without departing from the scope of embodiments of this disclosure, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to a determination."

[0031] For the sake of brevity and ease of understanding, this document uses the terms "greater than" or "less than", "higher than" or "lower than" to describe size relationships. However, it will be understood by those skilled in the art that the term "greater than" also includes the meaning of "greater than or equal to", and "less than" also includes the meaning of "less than or equal to"; the term "higher than" also includes the meaning of "higher than or equal to", and "lower than" also includes the meaning of "lower than or equal to".

[0032] Figure 1 This is a schematic flowchart illustrating a capability information transmission method according to an embodiment of the present disclosure. The capability information transmission method shown in this embodiment can be executed by a terminal, which includes, but is not limited to, communication devices such as mobile phones, tablets, wearable devices, sensors, and IoT devices. The terminal can communicate with network devices, which include, but are not limited to, network devices in 4G, 5G, and 6G communication systems, such as base stations and core networks.

[0033] like Figure 1 As shown, the capability information transmission method may include the following steps: In step S101, capability information related to the uplink positioning reference signal is determined; In step S102, the capability information is sent to the network device.

[0034] In one embodiment, the terminal can determine its own uplink positioning reference signal-related capability information and then send the capability information to the network device. The uplink positioning reference signal includes, but is not limited to, a sounding reference signal (SRS).

[0035] In one embodiment, the terminal may spontaneously send the capability information, for example, by periodically sending the capability information or by sending the capability information when the capability information meets preset conditions.

[0036] In one embodiment, the terminal can send the capability information according to a request from the network device. For example, the network device can first send a request to the terminal to obtain the capability information, and after receiving the request, the terminal sends the capability information to the network device.

[0037] According to embodiments of this disclosure, the terminal sends capability information related to the uplink positioning reference signal to the network device, enabling the network device to accurately and comprehensively determine the relevant capabilities of the terminal's uplink positioning reference signal based on the received capability information. This allows the network device to appropriately configure the terminal's uplink positioning reference signal transmission operation as needed when relevant services need to be performed based on the uplink positioning reference signal.

[0038] It should be noted that the capability information mentioned is only auxiliary information for network devices and cannot determine how the network device will configure the terminal. In other words, the specific configuration of the terminal by the network device is still determined by the network device itself. For example, the network device can comprehensively analyze the auxiliary information sent by multiple terminals and the network load to decide whether to configure the terminal accordingly based on the received capability information.

[0039] In one embodiment, the capability information is carried in a Radio Resource Control (RRC) message or a Long Term Evolution Positioning Protocol (LPP) message.

[0040] For example, when the network device includes a base station, the terminal can send the capability information to the base station via an RRC message; for example, when the network device includes a core network, the network device can send the capability information to the core network via an LPP message, and the core network may include an LMF (Location Management Function).

[0041] In one embodiment, sending the capability information to the network device includes: The network device is sent with information about the supported positioning algorithms, wherein the capability information is carried in the positioning algorithm information.

[0042] When a terminal performs positioning by sending uplink positioning reference signals, it also needs to report the supported positioning algorithm information, such as multi-RTT (Multi-cell Round TripTime), UL-TDOA (Uplink Time Difference of Arrival), UL-AoD (Uplink Angle of Departure), and UL-carrier phase. The terminal can report this capability information along with the supported positioning algorithm information to the network device.

[0043] In one embodiment, the capability information includes at least one of the following: The ability to support uplink positioning reference signals for associated valid areas, including uplink positioning reference signals that support associated valid areas and uplink positioning reference signals that do not support associated valid areas; The ability to support uplink positioning reference signals with associated valid time, including uplink positioning reference signals that support associated valid time and uplink positioning reference signals that do not support associated valid time; The ability to adjust the uplink positioning reference signal transmission power of the associated valid area, including both support for adjusting the uplink positioning reference signal transmission power of the associated valid area and non-support for adjusting the uplink positioning reference signal transmission power of the associated valid area; The ability to adjust the uplink positioning reference signal transmission power for the associated validity period, including both options that support adjusting the uplink positioning reference signal transmission power for the associated validity period and those that do not support adjusting the uplink positioning reference signal transmission power for the associated validity period; The ability to determine the timing advance (TA) of the uplink positioning reference signal based on the relevant information of the first signal includes both supporting the determination of the TA of the uplink positioning reference signal based on the relevant information of the first signal and not supporting the determination of the TA of the uplink positioning reference signal based on the relevant information of the first signal. The ability to determine the adjustment value of the TA based on relevant information of the second signal includes supporting the determination of the adjustment value of the TA based on relevant information of the second signal and not supporting the determination of the adjustment value of the TA based on relevant information of the second signal; The ability to send uplink positioning reference signals to network devices is supported, including both supporting and not supporting the sending of uplink positioning reference signals to network devices.

[0044] In one embodiment, the relevant information of the first signal and / or the relevant information of the second signal includes at least one of the following: Path loss; Intensity, such as Reference Signal Receiving Power; Signal-to-interference-plus-noise ratio (SINR).

[0045] 5G NR (New Radio) introduces a variety of positioning technologies to enable terminal positioning. Among them, uplink positioning technology and uplink-downlink hybrid positioning technology require the terminal to send uplink positioning reference signals. Therefore, network equipment needs to configure the terminal to send uplink positioning reference signals, such as the timing advance (TA) for sending uplink positioning reference signals.

[0046] Currently, it supports the location of terminals in non-connected states (e.g., inactive or idle states), meaning that terminals can send uplink location reference signals even when in a non-connected state. It also specifies that when a terminal performs cell reselection in an inactive state, it needs to release the configuration for the uplink location reference signal (e.g., the TA for sending the uplink location reference signal). This means that during cell reselection, the terminal stops sending the uplink location reference signal because there is no configuration for it (e.g., TA), making it impossible to locate the terminal based on the uplink location reference signal during this period.

[0047] After the terminal completes cell reselection, it needs to retrieve the uplink positioning reference signal configuration information from the network device again. In scenarios where the terminal moves quickly and performs cell reselection frequently, this leads to the terminal retrieving configuration information relatively frequently, resulting in significant consumption of communication resources and terminal power.

[0048] Figure 2 This is a schematic flowchart illustrating another capability information transmission method according to embodiments of this disclosure. Figure 2 As shown, the method further includes: In step S201, area indication information sent by the network device is received; In step S202, a valid region is determined based on the region indication information; In step S203, when the first cell where the cell reselection is located is within the effective area, it sends the uplink positioning reference signal using the uplink positioning reference signal configuration information provided by the cell where it was located when receiving the area indication information; The capability to support uplink positioning reference signals associated with valid areas includes: supporting uplink positioning reference signals associated with valid areas.

[0049] In one embodiment, the ability to support uplink positioning reference signals associated with a valid area includes two cases: supporting uplink positioning reference signals associated with a valid area and not supporting uplink positioning reference signals associated with a valid area.

[0050] When the terminal supports uplink positioning reference signals associated with a valid area, the network device can determine the uplink positioning reference signals associated with a valid area based on the capability information, and then select to configure a valid area for the terminal, for example, by indicating the valid area to the terminal through area indication information.

[0051] The terminal can determine the valid area based on the area indication information. Then, after cell reselection, it can determine whether the first cell it is in (e.g., the reselected cell) is within the valid area. If the first cell is within the valid area, it can continue to send the uplink positioning reference signal using the uplink positioning reference signal configuration information provided by the cell it was in when receiving the area indication information. This eliminates the need to re-obtain the uplink positioning reference signal configuration information from the network device (e.g., send an acquisition request to the network device), thus reducing the consumption of communication resources and terminal power.

[0052] If the first cell is not within the effective area, the terminal can obtain the configuration information of the uplink positioning reference signal from the network device again.

[0053] If the terminal does not support the uplink positioning reference signal associated with the valid area, the network device can determine from its capability information that the terminal does not support the uplink positioning reference signal associated with the area time, and thus can choose not to configure a valid area for the terminal. In this case, after cell reselection, the terminal can release the configuration information of the uplink positioning reference signal, and can also re-obtain the configuration information of the uplink positioning reference signal from the network device in the reselected cell.

[0054] Figure 3 This is a schematic flowchart illustrating yet another capability information transmission method according to embodiments of the present disclosure. Figure 3 As shown, the method further includes: In step S301, the uplink positioning reference signal configuration associated with the cell in the effective area is received from the network device; In step S302, within the effective area, the transmission power of the positioning reference signal is adjusted according to the uplink positioning reference signal configuration associated with the cell. The capability to support adjusting the uplink positioning reference signal transmission power of the associated valid area includes: supporting the adjustment of the uplink positioning reference signal transmission power of the associated valid area.

[0055] In one embodiment, the ability to adjust the uplink positioning reference signal transmission power of the associated valid area includes two cases: supporting the adjustment of the uplink positioning reference signal transmission power of the associated valid area and not supporting the adjustment of the uplink positioning reference signal transmission power of the associated valid area.

[0056] Since the distance between the terminal and the network device can vary at different locations within the effective area, if the power of the uplink positioning reference signal sent by the terminal remains constant, the strength of the uplink positioning reference signal received by the network device will be relatively weak at locations farther away from the network device within the effective area, thus affecting the reception effect.

[0057] When the terminal supports adjusting the uplink positioning reference signal transmission power of the associated valid area, the network device can determine that the terminal supports adjusting the uplink positioning reference signal transmission power of the associated valid area based on the capability information, and then choose to send the uplink positioning reference signal configuration associated with the cell in the valid area to the terminal.

[0058] The configuration of uplink positioning reference signals associated with cells in the effective area includes, but is not limited to, the relationship between the power adjustment parameters of the uplink positioning reference signals and the cells. For example, for cells that are relatively far from the network equipment, the power adjustment parameters can be set to positive (that is, the terminal can increase the transmission power of the uplink positioning reference signals), and for cells that are relatively far from the network equipment, the power adjustment parameters can be set to negative (that is, the terminal can reduce the transmission power of the uplink positioning reference signals).

[0059] After cell reselection, the terminal can determine whether its first cell (e.g., the reselected cell) is within the valid area. If the first cell is within the valid area, the terminal can further adjust the uplink positioning reference signal transmission power based on the configuration of the uplink positioning reference signal associated with the cell. For example, if it is determined that the cell is relatively far from the network device, the uplink positioning reference signal transmission power can be increased; if it is determined that the cell is relatively close to the network device, the uplink positioning reference signal transmission power can be decreased. This ensures that the uplink positioning reference signal transmission power is adapted to the cell where the terminal is located, which helps ensure the strength of the uplink positioning reference signal received by the network device.

[0060] If the terminal does not support adjusting the uplink positioning reference signal transmission power of the associated valid area, the network device can determine from the capability information that the terminal does not support adjusting the uplink positioning reference signal transmission power of the associated valid area, and thus can choose not to send the uplink positioning reference signal configuration associated with the cell in the valid area to the terminal.

[0061] It should be noted that network devices may also only indicate information to the terminal area for the terminal to determine the effective area, but do not send uplink positioning reference signal configuration associated with the cell in the effective area to the terminal. In this case, the terminal may not need to adjust the positioning reference signal transmission power within the effective area, or it may adjust the positioning reference signal transmission power according to the pre-stored adjustment parameters.

[0062] Figure 4This is a schematic flowchart illustrating yet another capability information transmission method according to embodiments of the present disclosure. Figure 4 As shown, the method further includes: In step S401, time indication information sent by the network device is received; In step S402, the valid time is determined according to the time indication information; In step S403, when the time after cell reselection is within the effective time, the uplink positioning reference signal is sent using the uplink positioning reference signal configuration information provided by the cell where the time indication information is received; The capability to support uplink positioning reference signals with associated valid time includes: supporting uplink positioning reference signals with associated valid time.

[0063] In one embodiment, the ability to support uplink positioning reference signals with associated valid time includes two cases: supporting uplink positioning reference signals with associated valid time and not supporting uplink positioning reference signals with associated valid time.

[0064] When the terminal supports uplink positioning reference signals with associated valid time, the network device can determine the uplink positioning reference signals supported by the terminal based on the capability information, and then choose to configure the valid time for the terminal, for example, by indicating the valid time to the terminal through time indication information.

[0065] The terminal can determine the valid time based on the time indication information. After cell reselection, it can then determine whether the reselected time (or other times, such as the time when the terminal needs to send the uplink positioning reference signal) is within the valid time. If the first cell is within the valid time, it can continue to use the uplink positioning reference signal configuration information provided by the cell where it was located when receiving the area indication information to send the uplink positioning reference signal. This avoids the need to re-obtain the uplink positioning reference signal configuration information from the network device (e.g., by sending an acquisition request to the network device), thus reducing the consumption of communication resources and terminal power.

[0066] If the time after cell reselection is not within the valid time, the terminal can obtain the configuration information of the uplink positioning reference signal from the network device again.

[0067] If the terminal does not support an uplink positioning reference signal with an associated valid time, the network device can determine from its capability information that the terminal does not support such an uplink positioning reference signal and can therefore choose not to configure a valid time for the terminal. In this case, after cell reselection, the terminal can release the configuration information of the uplink positioning reference signal and can also re-obtain the configuration information of the uplink positioning reference signal from the network device in the reselected cell.

[0068] Figure 5 This is a schematic flowchart illustrating yet another capability information transmission method according to embodiments of the present disclosure. Figure 5 As shown, the method further includes: In step S501, the uplink positioning reference signal configuration associated with a time period in the effective time is received from the network device; In step S502, during the effective time period, the transmission power of the positioning reference signal is adjusted according to the uplink positioning reference signal configuration associated with the time period. The capability to support adjusting the uplink positioning reference signal transmission power for the associated valid time includes: supporting adjusting the uplink positioning reference signal transmission power for the associated valid time.

[0069] In one embodiment, the ability to adjust the uplink positioning reference signal transmission power associated with the valid time includes two cases: supporting the adjustment of the uplink positioning reference signal transmission power associated with the valid time and not supporting the adjustment of the uplink positioning reference signal transmission power associated with the valid time.

[0070] Since the terminal's state (e.g., distance to network devices, speed of movement, etc.) is changing in some situations, the further away from the first time after receiving the uplink positioning reference signal configuration information in the cell where the terminal is located when receiving the time indication information, the greater the change in the distance between the terminal and the network device may be.

[0071] If the power of the uplink positioning reference signal transmitted by the terminal remains constant when the distance between the terminal and the network device changes, the strength of the uplink positioning reference signal received by the network device will be relatively weak at a distance farther from the network device, thus affecting the reception effect.

[0072] When the terminal supports adjusting the uplink positioning reference signal transmission power associated with the valid time, the network device can determine that the terminal supports adjusting the uplink positioning reference signal transmission power associated with the valid time based on the capability information, and then can choose to send uplink positioning reference signal configurations associated with time periods in the valid time to the terminal.

[0073] The configuration of the uplink positioning reference signal associated with the time period in the effective time includes, but is not limited to, the relationship between the power adjustment parameter of the uplink positioning reference signal and the time period. For example, for a time period that is relatively far from the first time, the power adjustment parameter can be set to positive (that is, the terminal can increase the transmission power of the uplink positioning reference signal), and for a time period that is relatively far from the first time, the power adjustment parameter can be set to negative (that is, the terminal can reduce the transmission power of the uplink positioning reference signal).

[0074] After cell reselection, the terminal can determine whether its current time period is within the valid time frame. If the time period is within the valid time frame, it can further adjust the uplink positioning reference signal transmission power based on the configuration of the associated time period. For example, if the current time period is relatively far from the first time frame, the uplink positioning reference signal transmission power can be increased; if the current time period is relatively close to the first time frame, the uplink positioning reference signal transmission power can be decreased. This ensures that the uplink positioning reference signal transmission power is adapted to the cell where the terminal is located, which helps ensure the strength of the uplink positioning reference signal received by network equipment.

[0075] If the terminal does not support adjusting the uplink positioning reference signal transmission power associated with the valid time, the network device can determine from the capability information that the terminal does not support adjusting the uplink positioning reference signal transmission power associated with the valid time, and can then choose not to send the uplink positioning reference signal configuration associated with the time period in the valid time to the terminal.

[0076] It should be noted that network devices may also only provide time indication information to the terminal for the terminal to determine the valid time, but without sending the uplink positioning reference signal configuration associated with the time period within the valid time. In this case, the terminal may not need to adjust the positioning reference signal transmission power within the valid time, or it may adjust the positioning reference signal transmission power according to the pre-stored adjustment parameters.

[0077] Figure 6 This is a schematic flowchart illustrating yet another capability information transmission method according to embodiments of the present disclosure. Figure 6 As shown, the method further includes: In step S601, TA is determined based on the relevant information of the first signal and the first correlation relationship between the relevant information of the first signal and TA; In step S602, an uplink positioning reference signal is sent to the network device according to the determined TA; The ability to support determining the TA of the uplink positioning reference signal based on the relevant information of the first signal includes: supporting the determination of the TA of the uplink positioning reference signal based on the relevant information of the first signal.

[0078] In one embodiment, the ability to determine the TA of the uplink positioning reference signal based on the relevant information of the first signal is supported, including two cases: supporting the determination of the TA of the uplink positioning reference signal based on the relevant information of the first signal and not supporting the determination of the TA of the uplink positioning reference signal based on the relevant information of the first signal.

[0079] If the terminal supports determining the transmission TA based on the relevant information of the first signal, the network device can determine the terminal's ability to determine the transmission TA based on the capability information, and then select to configure the first association relationship for the terminal.

[0080] After cell reselection, the terminal can determine the TA based on the relevant information of the first signal and the first association between the relevant information of the first signal and the TA. Then, it can send an uplink positioning reference signal to the network device based on the determined TA, thereby avoiding the problem of stopping the transmission of positioning reference signals when the TA is invalid after cell reselection.

[0081] If the terminal does not support determining the transmission TA based on the relevant information of the first signal, the network device can determine based on the capability information that the terminal does not support determining the transmission TA based on the relevant information of the first signal, and thus can choose not to configure the first association relationship for the terminal.

[0082] It should be noted that network devices may not configure the first association for the terminal. In this case, after the terminal performs cell reselection, it can continue to use the TA used when receiving the uplink positioning reference configuration information of the cell to send the uplink positioning reference signal.

[0083] In one embodiment, the first association relationship includes a non-continuous association relationship between the first information and TA, and / or a continuous association relationship between the first information and TA.

[0084] In one embodiment, the first association between the first information and the TA may be discontinuous.

[0085] For example, when the first information includes the RSRP of the reference signal, the first association relationship can be the correspondence between the RSRP and TA of multiple sets of first signals, such as {TA1, RSRP1}, {TA2, RSRP2}. Based on this, it can be determined that when the RSRP of the received reference signal is RSRP1, the corresponding TA is TA1, and when the RSRP of the received reference signal is RSRP2, the corresponding TA is TA2.

[0086] When the first information includes relevant information about the first signal, the relevant information about the first signal can be quantized into 3847 values, which correspond one-to-one with 3847 TAs.

[0087] In this case, the first association can be stored in a table, which contains the first information and the corresponding TA. For example, there can be a one-to-one correspondence between the first information and the TA.

[0088] In one embodiment, the first association between the first information and the TA can be continuous. For example, the first correlation can be a function with the first information as the independent variable and TA as the dependent variable. For instance, when the first information includes the RSRP of the reference signal, the first correlation can be TA=f(RSRP). After receiving the reference signal, the terminal can substitute the RSRP of the reference signal into TA=f(RSRP) to obtain the corresponding TA.

[0089] It should be noted that, in addition to determining the TA based on the relevant information of the first signal and the first association between the relevant information of the first signal and the TA, the terminal can also determine the TA through other associations, such as determining the TA based on the association between the cell identifier and the TA and the identifier of the cell after reselection.

[0090] Figure 7 This is a schematic flowchart illustrating yet another capability information transmission method according to embodiments of the present disclosure. Figure 7 As shown, the method further includes: In step S701, the adjustment value of TA is determined based on the relevant information of the second signal and the second correlation between the relevant information of the second signal and TA; In step S702, the determined TA is adjusted according to the adjustment value; In step S703, an uplink positioning reference signal is sent to the network device according to the adjusted TA; The ability to support determining the adjustment value of the TA based on relevant information of the second signal includes: supporting the determination of the adjustment value of the TA based on relevant information of the second signal.

[0091] In one embodiment, the ability to determine the adjustment value of the TA based on relevant information of the second signal is supported, including both cases where the adjustment value of the TA is determined based on relevant information of the second signal and cases where the adjustment value of the TA is not determined based on relevant information of the second signal.

[0092] If the terminal supports determining the adjustment value of the TA based on the relevant information of the second signal, the network device can determine the terminal's ability to determine the adjustment value of the TA based on the capability information, and then select to configure a second association relationship for the terminal.

[0093] When determining the TA based on the association between the cell identifier and the TA, and the identifier of the cell after reselection, since the cell after reselection has a certain coverage range, the TA is generally larger when the terminal is farther away from the cell center, and generally smaller when the terminal is closer to the cell center. Therefore, the TA determined solely based on the identifier of the cell after reselection (not limited to the identifier, but also the frequency point) may have a certain error compared with the TA corresponding to the terminal's location in the cell after reselection.

[0094] Therefore, after determining the TA based on the association between the cell identifier and the TA and the identifier of the cell after reselection, the terminal can further obtain the second signal in the cell after reselection, determine the TA adjustment value corresponding to the relevant information of the obtained second signal based on the second association, adjust the determined TA based on the TA adjustment value, and finally send the positioning reference signal to the network device based on the adjusted TA.

[0095] Since the terminal is located in a different cell after reselection, the relevant information of the second signal is also different. Therefore, the TA adjustment value corresponding to the relevant information of the second signal is determined according to the second association relationship, and the determined TA is adjusted according to the TA adjustment value. This helps to ensure that the adjusted TA is as close as possible (e.g., equal) to the TA corresponding to the location of the terminal in the cell after reselection, so that the terminal can use the appropriate TA (i.e., the adjusted TA) to send the positioning reference signal.

[0096] After cell reselection, the terminal can determine the TA based on the relevant information of the second signal and the second correlation between the relevant information of the second signal and the TA, then adjust the determined TA according to the adjustment value, and send an uplink positioning reference signal to the network device according to the adjusted TA, so that the terminal can send the positioning reference signal using an appropriate TA.

[0097] If the terminal does not support determining the adjustment value of the TA based on the relevant information of the second signal, the network device can determine based on the capability information that the terminal does not support determining the adjustment value of the TA based on the relevant information of the second signal, and thus can choose not to configure the second association relationship for the terminal.

[0098] Figure 8A This is a schematic flowchart illustrating yet another capability information transmission method according to embodiments of the present disclosure. Figure 8A As shown, the method further includes: In step S801, configuration information of the uplink positioning reference signal sent by the network device is received; In step S802, an uplink positioning reference signal is sent to the network device according to the configuration information; The capability to support sending uplink positioning reference signals to network devices includes: supporting the sending of uplink positioning reference signals to network devices.

[0099] In one embodiment, the ability to send uplink positioning reference signals to network devices includes two cases: supporting the sending of uplink positioning reference signals to network devices and not supporting the sending of uplink positioning reference signals to network devices.

[0100] When the terminal supports sending uplink positioning reference signals to the network device, the network device can determine that the terminal supports sending uplink positioning reference signals to the network device based on the capability information. Then, it can select the configuration information to send uplink positioning reference signals to the terminal, so that the terminal can send uplink positioning reference signals to the network device according to the received configuration information.

[0101] If the terminal does not support sending uplink positioning reference signals to the network device, the network device can determine from the capability information that the terminal does not support sending uplink positioning reference signals to the network device, and can then choose not to send uplink positioning reference signals to the terminal.

[0102] Figures 8B to 8D This is a schematic diagram illustrating the interaction between a network device and a terminal according to embodiments of the present disclosure.

[0103] In all embodiments of this disclosure, the terminal may spontaneously (e.g., periodically or when the terminal needs to be located) send the capability information to the network device, or it may send the capability information to the network device after receiving a request / query information sent by the network device.

[0104] When the network equipment includes a core network (such as the LMF in the core network), the interaction between the terminal and the core network can be achieved through LPP (LTE Positioning Protocol) messages; when the network equipment includes a base station, the interaction between the terminal and the base station can be achieved through RRC (Radio Resource Control) messages.

[0105] In one embodiment, such as Figure 8B As shown, the network device includes a core network, such as an LMF in the core network. The terminal can spontaneously send the capability information to the LMF, for example, by carrying it in an LPP capabilities provide message.

[0106] In one embodiment, such as Figure 8C As shown, the network device includes a core network, such as the LMF in the core network. The LMF can first send a capability acquisition request to the terminal, such as an LPP capabilities request message. After receiving the capability acquisition request, the terminal can send the capability information to the LMF, for example, by carrying it in an LPP capabilities provide message.

[0107] In one embodiment, such as Figure 8DAs shown, when the network device includes a base station, the base station can first send capability query information, such as UECapabilityEnquiry (User Equipment Capability Query) information, to the terminal. After receiving the capability query information, the terminal can send the capability information to the base station, for example, by carrying it in UECapabilityInformation (User Equipment Capability Information) and sending it to the base station.

[0108] Figure 9 This is a schematic flowchart illustrating a capability determination method according to an embodiment of the present disclosure. The capability determination method shown in this embodiment can be executed by a network device that can communicate with a terminal. The network device includes, but is not limited to, base stations in communication systems such as 4G base stations, 5G base stations, and 6G base stations. The terminal includes, but is not limited to, communication devices such as mobile phones, tablets, wearable devices, sensors, and IoT devices.

[0109] like Figure 9 As shown, the capability determination method may include the following steps: In step S901, the capability information sent by the receiving terminal is received; In step S902, the uplink positioning reference signal related capability of the terminal is determined based on the capability information.

[0110] In one embodiment, the terminal can determine its own uplink positioning reference signal-related capability information and then send the capability information to the network device. The uplink positioning reference signal includes, but is not limited to, a sounding reference signal (SRS).

[0111] In one embodiment, the terminal may spontaneously send the capability information, for example, by periodically sending the capability information or by sending the capability information when the capability information meets preset conditions.

[0112] In one embodiment, the terminal can send the capability information according to a request from the network device. For example, the network device can first send a request to the terminal to obtain the capability information, and after receiving the request, the terminal sends the capability information to the network device.

[0113] According to embodiments of this disclosure, the terminal sends capability information related to the uplink positioning reference signal to the network device, enabling the network device to accurately and comprehensively determine the relevant capabilities of the terminal's uplink positioning reference signal based on the received capability information. This allows the network device to appropriately configure the terminal's uplink positioning reference signal transmission operation as needed when relevant services need to be performed based on the uplink positioning reference signal.

[0114] In one embodiment, the capability information includes at least one of the following: The ability to support uplink positioning reference signals in associated valid areas; Supports the ability to associate uplink positioning reference signals with valid time. Supports the ability to adjust the uplink positioning reference signal transmission power of the associated valid area; Supports the ability to adjust the uplink positioning reference signal transmission power for the associated validity period; Supports the ability to determine the timing advance (TA) of the uplink positioning reference signal based on relevant information of the first signal; Supports the ability to determine the adjustment value of the TA based on relevant information from the second signal; It supports the ability to send uplink positioning reference signals to network devices.

[0115] In one embodiment, the relevant information of the first signal and / or the relevant information of the second signal includes at least one of the following: path loss; intensity; signal-to-interference-plus-noise ratio.

[0116] In one embodiment, the capability information is carried in a Radio Resource Control (RRC) message or a Long Term Evolution (LPP) message.

[0117] For example, when the network device includes a base station, the terminal can send the capability information to the base station via an RRC message; for example, when the network device includes a core network, the network device can send the capability information to the core network via an LPP message, and the core network may include an LMF.

[0118] It should be noted that the capability information mentioned is only auxiliary information for network devices and cannot determine how the network device will configure the terminal. In other words, the specific configuration of the terminal by the network device is still determined by the network device itself. For example, the network device can comprehensively analyze the auxiliary information sent by multiple terminals and the network load to decide whether to configure the terminal accordingly based on the received capability information.

[0119] The following examples illustrate how network devices configure terminals according to capability information.

[0120] In one embodiment, the ability to support uplink positioning reference signals associated with a valid area includes two cases: supporting uplink positioning reference signals associated with a valid area and not supporting uplink positioning reference signals associated with a valid area.

[0121] When the terminal supports uplink positioning reference signals associated with a valid area, the network device can determine the uplink positioning reference signals associated with a valid area based on the capability information, and then select to configure a valid area for the terminal, for example, by indicating the valid area to the terminal through area indication information.

[0122] The terminal can determine the valid area based on the area indication information. Then, after cell reselection, it can determine whether the first cell it is in (e.g., the reselected cell) is within the valid area. If the first cell is within the valid area, it can continue to send the uplink positioning reference signal using the uplink positioning reference signal configuration information provided by the cell it was in when receiving the area indication information. This eliminates the need to re-obtain the uplink positioning reference signal configuration information from the network device (e.g., send an acquisition request to the network device), thus reducing the consumption of communication resources and terminal power.

[0123] If the first cell is not within the effective area, the terminal can obtain the configuration information of the uplink positioning reference signal from the network device again.

[0124] If the terminal does not support the uplink positioning reference signal associated with the valid area, the network device can determine from its capability information that the terminal does not support the uplink positioning reference signal associated with the area time, and thus can choose not to configure a valid area for the terminal. In this case, after cell reselection, the terminal can release the configuration information of the uplink positioning reference signal, and can also re-obtain the configuration information of the uplink positioning reference signal from the network device in the reselected cell.

[0125] In one embodiment, the ability to adjust the uplink positioning reference signal transmission power of the associated valid area includes two cases: supporting the adjustment of the uplink positioning reference signal transmission power of the associated valid area and not supporting the adjustment of the uplink positioning reference signal transmission power of the associated valid area.

[0126] Since the distance between the terminal and the network device can vary at different locations within the effective area, if the power of the uplink positioning reference signal sent by the terminal remains constant, the strength of the uplink positioning reference signal received by the network device will be relatively weak at locations farther away from the network device within the effective area, thus affecting the reception effect.

[0127] When the terminal supports adjusting the uplink positioning reference signal transmission power of the associated valid area, the network device can determine that the terminal supports adjusting the uplink positioning reference signal transmission power of the associated valid area based on the capability information, and then choose to send the uplink positioning reference signal configuration associated with the cell in the valid area to the terminal.

[0128] The configuration of uplink positioning reference signals associated with cells in the effective area includes, but is not limited to, the relationship between the power adjustment parameters of the uplink positioning reference signals and the cells. For example, for cells that are relatively far from the network equipment, the power adjustment parameters can be set to positive (that is, the terminal can increase the transmission power of the uplink positioning reference signals), and for cells that are relatively far from the network equipment, the power adjustment parameters can be set to negative (that is, the terminal can reduce the transmission power of the uplink positioning reference signals).

[0129] After cell reselection, the terminal can determine whether its first cell (e.g., the reselected cell) is within the valid area. If the first cell is within the valid area, the terminal can further adjust the uplink positioning reference signal transmission power based on the configuration of the uplink positioning reference signal associated with the cell. For example, if it is determined that the cell is relatively far from the network device, the uplink positioning reference signal transmission power can be increased; if it is determined that the cell is relatively close to the network device, the uplink positioning reference signal transmission power can be decreased. This ensures that the uplink positioning reference signal transmission power is adapted to the cell where the terminal is located, which helps ensure the strength of the uplink positioning reference signal received by the network device.

[0130] If the terminal does not support adjusting the uplink positioning reference signal transmission power of the associated valid area, the network device can determine from the capability information that the terminal does not support adjusting the uplink positioning reference signal transmission power of the associated valid area, and thus can choose not to send the uplink positioning reference signal configuration associated with the cell in the valid area to the terminal.

[0131] It should be noted that network devices may also only indicate information to the terminal area for the terminal to determine the effective area, but do not send uplink positioning reference signal configuration associated with the cell in the effective area to the terminal. In this case, the terminal may not need to adjust the positioning reference signal transmission power within the effective area, or it may adjust the positioning reference signal transmission power according to the pre-stored adjustment parameters.

[0132] In one embodiment, the ability to support uplink positioning reference signals with associated valid time includes two cases: supporting uplink positioning reference signals with associated valid time and not supporting uplink positioning reference signals with associated valid time.

[0133] When the terminal supports uplink positioning reference signals with associated valid time, the network device can determine the uplink positioning reference signals supported by the terminal based on the capability information, and then choose to configure the valid time for the terminal, for example, by indicating the valid time to the terminal through time indication information.

[0134] The terminal can determine the valid time based on the time indication information. After cell reselection, it can then determine whether the reselected time (or other times, such as the time when the terminal needs to send the uplink positioning reference signal) is within the valid time. If the first cell is within the valid time, it can continue to use the uplink positioning reference signal configuration information provided by the cell where it was located when receiving the area indication information to send the uplink positioning reference signal. This avoids the need to re-obtain the uplink positioning reference signal configuration information from the network device (e.g., by sending an acquisition request to the network device), thus reducing the consumption of communication resources and terminal power.

[0135] If the time after cell reselection is not within the valid time, the terminal can obtain the configuration information of the uplink positioning reference signal from the network device again.

[0136] If the terminal does not support an uplink positioning reference signal with an associated valid time, the network device can determine from its capability information that the terminal does not support such an uplink positioning reference signal and can therefore choose not to configure a valid time for the terminal. In this case, after cell reselection, the terminal can release the configuration information of the uplink positioning reference signal and can also re-obtain the configuration information of the uplink positioning reference signal from the network device in the reselected cell.

[0137] In one embodiment, the ability to adjust the uplink positioning reference signal transmission power associated with the valid time includes two cases: supporting the adjustment of the uplink positioning reference signal transmission power associated with the valid time and not supporting the adjustment of the uplink positioning reference signal transmission power associated with the valid time.

[0138] Since the terminal's state (e.g., distance to network devices, speed of movement, etc.) is changing in some situations, the further away from the first time after receiving the uplink positioning reference signal configuration information in the cell where the terminal is located when receiving the time indication information, the greater the change in the distance between the terminal and the network device may be.

[0139] If the power of the uplink positioning reference signal transmitted by the terminal remains constant when the distance between the terminal and the network device changes, the strength of the uplink positioning reference signal received by the network device will be relatively weak at a distance farther from the network device, thus affecting the reception effect.

[0140] When the terminal supports adjusting the uplink positioning reference signal transmission power associated with the valid time, the network device can determine that the terminal supports adjusting the uplink positioning reference signal transmission power associated with the valid time based on the capability information, and then can choose to send uplink positioning reference signal configurations associated with time periods in the valid time to the terminal.

[0141] The configuration of the uplink positioning reference signal associated with the time period in the effective time includes, but is not limited to, the relationship between the power adjustment parameter of the uplink positioning reference signal and the time period. For example, for a time period that is relatively far from the first time, the power adjustment parameter can be set to positive (that is, the terminal can increase the transmission power of the uplink positioning reference signal), and for a time period that is relatively far from the first time, the power adjustment parameter can be set to negative (that is, the terminal can reduce the transmission power of the uplink positioning reference signal).

[0142] After cell reselection, the terminal can determine whether its current time period is within the valid time frame. If the time period is within the valid time frame, it can further adjust the uplink positioning reference signal transmission power based on the configuration of the associated time period. For example, if the current time period is relatively far from the first time frame, the uplink positioning reference signal transmission power can be increased; if the current time period is relatively close to the first time frame, the uplink positioning reference signal transmission power can be decreased. This ensures that the uplink positioning reference signal transmission power is adapted to the cell where the terminal is located, which helps ensure the strength of the uplink positioning reference signal received by network equipment.

[0143] If the terminal does not support adjusting the uplink positioning reference signal transmission power associated with the valid time, the network device can determine from the capability information that the terminal does not support adjusting the uplink positioning reference signal transmission power associated with the valid time, and can then choose not to send the uplink positioning reference signal configuration associated with the time period in the valid time to the terminal.

[0144] In one embodiment, the ability to determine the TA of the uplink positioning reference signal based on the relevant information of the first signal is supported, including two cases: supporting the determination of the TA of the uplink positioning reference signal based on the relevant information of the first signal and not supporting the determination of the TA of the uplink positioning reference signal based on the relevant information of the first signal.

[0145] If the terminal supports determining the transmission TA based on the relevant information of the first signal, the network device can determine the terminal's ability to determine the transmission TA based on the capability information, and then select to configure the first association relationship for the terminal.

[0146] After cell reselection, the terminal can determine the TA based on the relevant information of the first signal and the first association between the relevant information of the first signal and the TA. Then, it can send an uplink positioning reference signal to the network device based on the determined TA, thereby avoiding the problem of stopping the transmission of positioning reference signals when the TA is invalid after cell reselection.

[0147] If the terminal does not support determining the transmission TA based on the relevant information of the first signal, the network device can determine based on the capability information that the terminal does not support determining the transmission TA based on the relevant information of the first signal, and thus can choose not to configure the first association relationship for the terminal.

[0148] It should be noted that network devices may not configure the first association for the terminal. In this case, after the terminal performs cell reselection, it can continue to use the TA used when receiving the uplink positioning reference configuration information of the cell to send the uplink positioning reference signal.

[0149] In one embodiment, the first association relationship includes a non-continuous association relationship between the first information and TA, and / or a continuous association relationship between the first information and TA.

[0150] In one embodiment, the first association between the first information and the TA may be discontinuous.

[0151] For example, when the first information includes the RSRP of the reference signal, the first association relationship can be the correspondence between the RSRP and TA of multiple sets of first signals, such as {TA1, RSRP1}, {TA2, RSRP2}. Based on this, it can be determined that when the RSRP of the received reference signal is RSRP1, the corresponding TA is TA1, and when the RSRP of the received reference signal is RSRP2, the corresponding TA is TA2.

[0152] When the first information includes relevant information about the first signal, the relevant information about the first signal can be quantized into 3847 values, which correspond one-to-one with 3847 TAs.

[0153] In this case, the first association can be stored in a table, which contains the first information and the corresponding TA. For example, there can be a one-to-one correspondence between the first information and the TA.

[0154] In one embodiment, the first association between the first information and the TA can be continuous. For example, the first correlation can be a function with the first information as the independent variable and TA as the dependent variable. For instance, when the first information includes the RSRP of the reference signal, the first correlation can be TA=f(RSRP). After receiving the reference signal, the terminal can substitute the RSRP of the reference signal into TA=f(RSRP) to obtain the corresponding TA.

[0155] It should be noted that, in addition to determining the TA based on the relevant information of the first signal and the first association between the relevant information of the first signal and the TA, the terminal can also determine the TA through other associations, such as determining the TA based on the association between the cell identifier and the TA and the identifier of the cell after reselection.

[0156] In one embodiment, the ability to determine the adjustment value of the TA based on relevant information of the second signal is supported, including both cases where the adjustment value of the TA is determined based on relevant information of the second signal and cases where the adjustment value of the TA is not determined based on relevant information of the second signal.

[0157] If the terminal supports determining the adjustment value of the TA based on the relevant information of the second signal, the network device can determine the terminal's ability to determine the adjustment value of the TA based on the capability information, and then select to configure a second association relationship for the terminal.

[0158] When determining the TA based on the association between the cell identifier and the TA, and the identifier of the cell after reselection, since the cell after reselection has a certain coverage range, the TA is generally larger when the terminal is farther away from the cell center, and generally smaller when the terminal is closer to the cell center. Therefore, the TA determined solely based on the identifier of the cell after reselection (not limited to the identifier, but also the frequency point) may have a certain error compared with the TA corresponding to the terminal's location in the cell after reselection.

[0159] Therefore, after determining the TA based on the association between the cell identifier and the TA and the identifier of the cell after reselection, the terminal can further obtain the second signal in the cell after reselection, determine the TA adjustment value corresponding to the relevant information of the obtained second signal based on the second association, adjust the determined TA based on the TA adjustment value, and finally send the positioning reference signal to the network device based on the adjusted TA.

[0160] Since the terminal is located in a different cell after reselection, the relevant information of the second signal is also different. Therefore, the TA adjustment value corresponding to the relevant information of the second signal is determined according to the second association relationship, and the determined TA is adjusted according to the TA adjustment value. This helps to ensure that the adjusted TA is as close as possible (e.g., equal) to the TA corresponding to the location of the terminal in the cell after reselection, so that the terminal can use the appropriate TA (i.e., the adjusted TA) to send the positioning reference signal.

[0161] After cell reselection, the terminal can determine the TA based on the relevant information of the second signal and the second correlation between the relevant information of the second signal and the TA, then adjust the determined TA according to the adjustment value, and send an uplink positioning reference signal to the network device according to the adjusted TA, so that the terminal can send the positioning reference signal using an appropriate TA.

[0162] If the terminal does not support determining the adjustment value of the TA based on the relevant information of the second signal, the network device can determine based on the capability information that the terminal does not support determining the adjustment value of the TA based on the relevant information of the second signal, and thus can choose not to configure the second association relationship for the terminal.

[0163] In one embodiment, the ability to send uplink positioning reference signals to network devices includes two cases: supporting the sending of uplink positioning reference signals to network devices and not supporting the sending of uplink positioning reference signals to network devices.

[0164] When the terminal supports sending uplink positioning reference signals to the network device, the network device can determine that the terminal supports sending uplink positioning reference signals to the network device based on the capability information. Then, it can select the configuration information to send uplink positioning reference signals to the terminal, so that the terminal can send uplink positioning reference signals to the network device according to the received configuration information.

[0165] If the terminal does not support sending uplink positioning reference signals to the network device, the network device can determine from the capability information that the terminal does not support sending uplink positioning reference signals to the network device, and can then choose not to send uplink positioning reference signals to the terminal.

[0166] Corresponding to the embodiments of the capability information transmission method and capability determination method described above, this disclosure also provides embodiments of the capability information transmission device and the capability determination device.
