Fig. 1 is a schematic flow chart diagram illustrating a capability information transmission method according to an embodiment of the present disclosure. The capability information sending method shown in the embodiment may be executed by a terminal, where the terminal includes, but is not limited to, a mobile phone, a tablet computer, a wearable device, a sensor, an internet of things device, and other communication devices. The terminal may communicate with network devices including, but not limited to, network devices in 4G, 5G, 6G, etc., communication systems, e.g., base stations, core networks, etc.

As shown in fig. 1, the capability information transmission method may include the steps of:

in step S101, capability information of the uplink positioning reference signal correlation capability is determined;

in step S102, the capability information is sent to the network device.

In one embodiment, the terminal may determine capability information of a capability related to the self uplink positioning reference signal, and then send the capability information to the network device. Wherein the uplink positioning reference signals include, but are not limited to, sounding reference signals SRS (Sounding Reference Signal).

In one embodiment, the terminal may autonomously transmit the capability information, for example, periodically transmit the capability information, and transmit the capability information when the capability information satisfies a preset condition.

In one embodiment, the terminal may send the capability information according to a request of the network device, for example, the network device may first send a request for obtaining the capability information to the terminal, and after receiving the request, the terminal sends the capability information to the network device.

It should be noted that, the capability information is used as auxiliary information for the network device, and it cannot be determined how the network device subsequently configures the terminal, that is, how the network device specifically configures the terminal, and still is determined by the network device itself, for example, the network device may comprehensively analyze auxiliary information and network load conditions sent by a plurality of terminals, and determine whether to perform corresponding configuration for the terminal according to the received capability information.

In one embodiment, the capability information is carried in a radio resource control RRC (Radio Resource Control) message or a long term evolution positioning protocol LPP (LTE Positioning Protocol) message.

For example, in the case that the network device includes a base station, the terminal may send the capability information to the base station through an RRC message; for example, in case the network device comprises a core network, the network device may send the capability information to the core network by means of LPP messages, which core network may comprise an LMF (Location Management Function ).

In one embodiment, the transmitting the capability information to the network device includes:

and sending the supported positioning algorithm information to the network equipment, wherein the positioning algorithm information carries the capability information.

When the terminal performs positioning by sending an uplink positioning reference signal, the terminal also needs to report the supported positioning algorithm information, such as Multi-RTT (Multi-cell Round Trip Time), UL-TDOA (uplink arrival Time difference, uplink Time Difference of Arrival), UL-AoD (uplink departure angle, angel of Departure), UL-carrier phase and other algorithms.

In one embodiment, the capability information includes at least one of:

the capability of supporting uplink positioning reference signals associated with the effective area comprises uplink positioning reference signals associated with the effective area and uplink positioning reference signals not associated with the effective area;

the capability of supporting uplink positioning reference signals associated with effective time comprises uplink positioning reference signals associated with effective time and uplink positioning reference signals not associated with effective time;

the capability of supporting adjustment of uplink positioning reference signal transmission power associated with the effective area comprises supporting adjustment of uplink positioning reference signal transmission power associated with the effective area and not supporting adjustment of uplink positioning reference signal transmission power associated with the effective area;

the capability of supporting the adjustment of the uplink positioning reference signal transmission power associated with the effective time comprises supporting the adjustment of the uplink positioning reference signal transmission power associated with the effective time and not supporting the adjustment of the uplink positioning reference signal transmission power associated with the effective time;

the ability to support determining the timing advance TA (Timing Advance) of the uplink positioning reference signal based on the correlation information of the first signal includes supporting a TA that determines the uplink positioning reference signal based on the correlation information of the first signal and a TA that does not support determining the uplink positioning reference signal based on the correlation information of the first signal;

Supporting the ability to determine an adjustment value for the TA based on the correlation information for the second signal, including supporting the determination of an adjustment value for the TA based on the correlation information for the second signal and not supporting the determination of an adjustment value for the TA based on the correlation information for the second signal;

the ability to support the transmission of uplink positioning reference signals to a network device includes supporting the transmission of uplink positioning reference signals to a network device and not supporting the transmission of uplink positioning reference signals to a network device.

In an embodiment, the related information of the first signal and/or the related information of the second signal comprises at least one of:

path loss path;

strength, e.g., reference Signal Receiving Power, reference signal received power;

signal to interference plus noise ratio SINR (Signal to Interference plus Noise Ratio).

Various positioning technologies are introduced into a 5G NR (New Radio), so that positioning of a terminal can be achieved, where in an uplink positioning technology and an uplink and downlink hybrid positioning technology, the terminal is required to send an uplink positioning reference signal, and therefore, network equipment is required to configure the uplink positioning reference signal sent by the terminal, for example, a timing advance TA of the uplink positioning reference signal is sent.

The positioning of the terminal in the non-connection state (such as inactive attitude and idle state) can be supported at present, that is, the terminal can send an uplink positioning reference signal when in the non-connection state. It is also specified that when the terminal performs cell reselection in an inactive state, the terminal needs to release the configuration of the uplink positioning reference signal (e.g. TA for transmitting the uplink positioning reference signal), which results in that when the terminal performs cell reselection, the terminal cannot be positioned according to the uplink positioning reference signal during this period because the configuration of the uplink positioning reference signal (e.g. TA) is not valid and the transmission of the uplink positioning reference signal is stopped.

After the terminal completes the cell reselection, the terminal needs to acquire the configuration information of the uplink positioning reference signal from the network device again. In a scenario that the terminal moves faster and frequent cell reselection is performed, the terminal can obtain configuration information relatively frequently, and therefore larger consumption is caused on communication resources and terminal electric quantity.

Fig. 2 is a schematic flow chart diagram illustrating another capability information transmission method according to an embodiment of the present disclosure. As shown in fig. 2, the method further includes:

in step S201, receiving area indication information sent by a network device;

In step S202, an effective area is determined according to the area indication information;

in step S203, when the first cell after cell reselection is in the effective area, the uplink positioning reference signal is sent by using uplink positioning reference signal configuration information provided by the cell in which the area indication information is received;

the capability of supporting the uplink positioning reference signals associated with the effective area comprises the following steps: and supporting the uplink positioning reference signals associated with the effective areas.

In one embodiment, the capability of supporting uplink positioning reference signals associated with an active area includes both cases of supporting uplink positioning reference signals associated with an active area and not supporting uplink positioning reference signals associated with an active area.

Under the condition that the terminal supports the uplink positioning reference signal associated with the effective area, the network equipment can determine the uplink positioning reference signal associated with the effective area supported by the terminal according to the capability information, and then can select to configure the effective area for the terminal, for example, the effective area is indicated to the terminal through the area indication information.

The terminal can determine an effective area according to the area indication information, and further after cell reselection, can determine whether the first cell (for example, the reselected cell) is in the effective area. If the first cell is in the effective area, the uplink positioning reference signal can be sent by continuing to use the uplink positioning reference signal configuration information provided by the cell in which the area indication information is received, so that the configuration information of the uplink positioning reference signal does not need to be acquired again from the network equipment (for example, an acquisition request is sent to the network equipment), and the consumption of communication resources and terminal electric quantity is reduced.

If the first cell is not in the effective area, the terminal can acquire the configuration information of the uplink positioning reference signal from the network equipment again.

Under the condition that the terminal does not support the uplink positioning reference signals of the associated effective area, the network equipment can determine the uplink positioning reference signals of the time when the terminal does not support the associated area according to the capability information, and then can select to not configure the effective area for the terminal. In this case, after cell reselection, the terminal may release the configuration information of the uplink positioning reference signal, and may acquire, again, the configuration information of the uplink positioning reference signal from the network device in the reselected cell.

Fig. 3 is a schematic flow chart diagram illustrating yet another capability information transmission method according to an embodiment of the present disclosure. As shown in fig. 3, the method further includes:

in step S301, receiving an uplink positioning reference signal configuration associated with a cell in an effective area sent by a network device;

in step S302, in the effective area, the positioning reference signal transmission power is adjusted according to the uplink positioning reference signal configuration associated with the cell;

the capability of supporting adjustment of the uplink positioning reference signal transmitting power of the associated effective area comprises the following steps: and supporting adjustment of the uplink positioning reference signal transmission power of the associated effective area.

In one embodiment, the ability to support adjustment of uplink positioning reference signal transmit power associated with the active area includes both cases of supporting adjustment of uplink positioning reference signal transmit power associated with the active area and not supporting adjustment of uplink positioning reference signal transmit power associated with the active area.

Because the distance between the terminal and the network device can be different in different positions in the effective area, if the power of the uplink positioning reference signal sent by the terminal is kept unchanged, the strength of the uplink positioning reference signal received by the network device is relatively smaller in a position far away from the network device in the effective area, so that the receiving effect is affected.

Under the condition that the terminal supports adjusting the uplink positioning reference signal transmitting power of the associated effective area, the network equipment can determine the terminal supports adjusting the uplink positioning reference signal transmitting power of the associated effective area according to the capability information, and then can select to transmit the uplink positioning reference signal configuration associated with the cell in the effective area to the terminal.

The configuration of the uplink positioning reference signal associated with the cell in the active area includes, but is not limited to, an association relationship between a power adjustment parameter of the uplink positioning reference signal and the cell, for example, for a cell relatively far from the network device, the power adjustment parameter may be set to be positive (i.e., the terminal may increase the transmission power of the uplink positioning reference signal), and for a cell relatively far from the network device, the power adjustment parameter may be set to be negative (i.e., the terminal may decrease the transmission power of the uplink positioning reference signal).

After performing cell reselection, the terminal may determine whether the first cell (e.g., the reselected cell) in which the terminal is located is in the active area. If the first cell is in the effective area, the transmission power of the positioning reference signal can be further adjusted according to the configuration of the uplink positioning reference signal associated with the cell, for example, when the cell is relatively far away from the network device, the transmission power of the uplink positioning reference signal can be increased, and when the cell is relatively near to the network device, the transmission power of the uplink positioning reference signal can be reduced. Accordingly, the transmitting power of the uplink positioning reference signal is adapted to the cell in which the terminal is located, so that the strength of the network equipment for receiving the uplink positioning reference signal is ensured.

Under the condition that the terminal does not support to adjust the uplink positioning reference signal transmission power of the associated effective area, the network equipment can determine that the terminal does not support to adjust the uplink positioning reference signal transmission power of the associated effective area according to the capability information, and then can select not to transmit uplink positioning reference signal configuration associated with a cell in the effective area to the terminal.

It should be noted that, the network device may only indicate information to the terminal area for the terminal to determine the effective area, but not send uplink positioning reference signal configuration associated with the cell in the effective area to the terminal, so that the terminal may not adjust the positioning reference signal transmission power in the effective area, or may adjust the positioning reference signal transmission power according to the prestored adjustment parameter.

Fig. 4 is a schematic flow chart diagram illustrating yet another capability information transmission method according to an embodiment of the present disclosure. As shown in fig. 4, the method further includes:

in step S401, time indication information sent by a network device is received;

in step S402, determining a valid time according to the time indication information;

in step S403, when the time after the cell reselection is within the effective time, the uplink positioning reference signal is sent by using uplink positioning reference signal configuration information provided by the cell in which the time indication information is received;

the capability of supporting the uplink positioning reference signal associated with the effective time comprises the following steps: and supporting the uplink positioning reference signals associated with the effective time.

In one embodiment, the ability to support uplink positioning reference signals associated with active time includes both cases of uplink positioning reference signals associated with active time and uplink positioning reference signals not associated with active time.

In the case that the terminal supports the uplink positioning reference signal associated with the effective time, the network device may determine, according to the capability information, that the terminal supports the uplink positioning reference signal associated with the effective time, and may further select to configure the effective time for the terminal, for example, indicate the effective time to the terminal through time indication information.

The terminal can determine the effective time according to the time indication information, and further after cell reselection, can determine whether the time after cell reselection (or other time, for example, the time when the terminal needs to send the uplink positioning reference signal) is within the effective time. If the first cell can continue to use the configuration information of the uplink positioning reference signal provided by the cell in which the area indication information is received to send the uplink positioning reference signal in the effective time, the configuration information of the uplink positioning reference signal does not need to be acquired again from the network equipment (for example, an acquisition request is sent to the network equipment), which is beneficial to reducing the consumption of communication resources and terminal electric quantity.

If the time after the cell reselection is not within the effective time, the terminal can acquire the configuration information of the uplink positioning reference signal from the network equipment again.

Under the condition that the terminal does not support the uplink positioning reference signals associated with the effective time, the network equipment can determine that the terminal does not support the uplink positioning reference signals associated with the effective time according to the capability information, and then can choose not to configure the effective time for the terminal. In this case, after cell reselection, the terminal may release the configuration information of the uplink positioning reference signal, and may acquire, again, the configuration information of the uplink positioning reference signal from the network device in the reselected cell.

Fig. 5 is a schematic flow chart diagram illustrating yet another capability information transmission method according to an embodiment of the present disclosure. As shown in fig. 5, the method further includes:

in step S501, receiving an uplink positioning reference signal configuration associated with a time period in an effective time sent by a network device;

in step S502, in the effective time, adjusting the transmission power of the positioning reference signal according to the uplink positioning reference signal configuration associated with the located time period;

the capability of supporting adjustment of the uplink positioning reference signal transmitting power associated with the effective time includes: and supporting adjustment of the uplink positioning reference signal transmission power of the associated effective time.

In one embodiment, the ability to support adjustment of uplink positioning reference signal transmit power associated with an active time includes both cases of supporting adjustment of uplink positioning reference signal transmit power associated with an active time and not supporting adjustment of uplink positioning reference signal transmit power associated with an active time.

Since the terminal is in a state (e.g., distance to the network device, movement speed, etc.) in some cases, the change in the distance from the terminal to the network device may be greater from the moment the first time is further after the first time of receiving the uplink positioning reference signal configuration information in the cell in which the time indication information is received.

In the case that the distance between the terminal and the network device is changed, if the power of the uplink positioning reference signal sent by the terminal is kept unchanged, the strength of the uplink positioning reference signal received by the network device is relatively small at a position far from the network device, thereby affecting the receiving effect.

Under the condition that the terminal supports adjusting the uplink positioning reference signal transmission power associated with the effective time, the network equipment can determine the uplink positioning reference signal transmission power associated with the effective time supported by the terminal according to the capability information, and then can select to transmit the uplink positioning reference signal configuration associated with the time period in the effective time to the terminal.

The configuration of the uplink positioning reference signal associated with the period of time in the effective time includes, but is not limited to, an association relationship between a power adjustment parameter of the uplink positioning reference signal and the period of time, for example, for a period of time relatively far from the first time, the power adjustment parameter may be set to be positive (i.e., the terminal may increase the transmission power of the uplink positioning reference signal), and for a period of time relatively far from the first time, the power adjustment parameter may be set to be negative (i.e., the terminal may decrease the transmission power of the uplink positioning reference signal).

After cell reselection, the terminal can determine whether the time period is within the effective time. If the time period is within the effective time, the uplink positioning reference signal configuration associated with the time period can be further used for adjusting the transmission power of the positioning reference signal, for example, when the time period is determined to be relatively far from the first time, the transmission power of the uplink positioning reference signal can be increased, and when the time period is determined to be relatively near from the first time, the transmission power of the uplink positioning reference signal can be reduced. Accordingly, the transmitting power of the uplink positioning reference signal is adapted to the cell in which the terminal is located, so that the strength of the network equipment for receiving the uplink positioning reference signal is ensured.

Under the condition that the terminal does not support to adjust the uplink positioning reference signal transmission power associated with the effective time, the network equipment can determine that the terminal does not support to adjust the uplink positioning reference signal transmission power associated with the effective time according to the capability information, and further can select not to transmit uplink positioning reference signal configuration associated with the time period in the effective time to the terminal.

It should be noted that, the network device may only send the terminal time indication information to the terminal to determine the effective time, but not send the uplink positioning reference signal configuration associated with the time period in the effective time to the terminal, so that the terminal may not adjust the positioning reference signal transmission power in the effective time, or may adjust the positioning reference signal transmission power according to the prestored adjustment parameter.

Fig. 6 is a schematic flow chart diagram illustrating yet another capability information transmission method according to an embodiment of the present disclosure. As shown in fig. 6, the method further includes:

in step S601, determining TA according to the related information of the first signal and a first association relationship between the related 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;

wherein the supporting the capability of determining the TA of the uplink positioning reference signal according to the related information of the first signal includes: and supporting the TA of determining the uplink positioning reference signal according to the related information of the first signal.

In one embodiment, the ability to support the determination of the TA of the uplink positioning reference signal based on the correlation information of the first signal includes both the case of supporting the determination of the TA of the uplink positioning reference signal based on the correlation information of the first signal and the case of not supporting the determination of the TA of the uplink positioning reference signal based on the correlation information of the first signal.

In the case that the terminal supports determining the TA at the time of transmission according to the related information of the first signal, the network device may determine, according to the capability information, that the terminal supports determining the TA at the time of transmission according to the related information of the first signal, and may further select to configure the first association relationship for the terminal.

After cell reselection, the terminal can determine the TA according to the related information of the first signal and the first association relation between the related information of the first signal and the TA, and then send an uplink positioning reference signal to the network equipment according to the determined TA, so that the problem that the transmission of the positioning reference signal is stopped under the condition that the TA is invalid after cell reselection is avoided.

In the case that the terminal does not support the TA when determining the transmission according to the related information of the first signal, the network device may determine, according to the capability information, that the terminal does not support the TA when determining the transmission according to the related information of the first signal, and may further choose not to configure the first association relationship for the terminal.

It should be noted that, the network device may not configure the first association relationship for the terminal, and after the terminal performs cell reselection, the terminal may continue to use the TA used when receiving the cell where the uplink positioning reference configuration information is located to send the uplink positioning reference signal.

In one embodiment, the first association relationship includes a discontinuous association relationship between the first information and the TA, and/or a continuous association relationship between the first information and the TA.

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

For example, when the first information includes RSRP of the reference signal, the first association relationship may be a correspondence relationship between RSRP and TA of the plurality of sets of first signals, for example { TA1, RSRP1}, { TA2, RSRP2}, from which it may be determined that when RSPR of the received reference signal is RSRP1, the corresponding TA is TA1, and when RSPR of the received reference signal is RSRP2, the corresponding TA is TA2.

Wherein, when the first information includes the related information of the first signal, the related information of the first signal may be quantized into 3847 values, which correspond to 3847 TAs one by one.

In this case, the first association relationship may be stored by a table, which contains TAs to which the first information corresponds, for example, the first information and the TAs may be in one-to-one correspondence.

In one embodiment, the first association between the first information and the TA may be continuous,

for example, the first association relationship may be a function of the first information as an argument and the TA as an argument. For example, when the first information includes an RSRP of the reference signal, the first association relationship may be ta=f (RSRP), and after receiving the reference signal, the terminal may substitute the RSRP of the reference signal into ta=f (RSRP), thereby obtaining the corresponding TA.

It should be noted that, the terminal may determine the TA according to the related information of the first signal and the first association relationship between the related information of the first signal and the TA, and may determine the TA according to other association relationships, for example, the association relationship between the cell identifier and the TA and the identifier of the cell after reselection.

Fig. 7 is a schematic flow chart diagram illustrating yet another capability information transmission method according to an embodiment of the present disclosure. As shown in fig. 7, the method further includes:

in step S701, an adjustment value of TA is determined according to the related information of the second signal and a second association relationship between the related 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;

wherein the supporting the ability to determine the adjustment value of the TA based on the information related to the second signal comprises: and supporting to determine the adjustment value of the TA according to the related information of the second signal.

In one embodiment, supporting the ability to determine the adjustment value of the TA based on the correlation information of the second signal includes supporting both the determination of the adjustment value of the TA based on the correlation information of the second signal and the non-support of the determination of the adjustment value of the TA based on the correlation information of the second signal.

And under the condition that the terminal supports determining the adjustment value of the TA according to the related information of the second signal, the network equipment can determine that the terminal supports determining the adjustment value of the TA according to the related information of the second signal according to the capability information, and then can select to configure a second association relation for the terminal.

Under the condition that the TA is determined according to the association relation between the cell identity and the TA and the identity of the cell after reselection, as the cell after reselection has a certain coverage, the TA is generally larger as the terminal is farther from the center of the cell, and is generally smaller as the terminal is closer to the center of the cell, a certain error may exist between the TA which is determined according to the identity (not limited to the identity, but also can be a frequency point) of the cell after reselection and the TA corresponding to the position of the terminal in the cell after reselection.

Therefore, after determining the TA according to the association between the cell identifier and the TA and the identifier of the cell in which the terminal is located after reselection, the terminal may further acquire the second signal in the cell in which the terminal is located after reselection, determine a TA adjustment value corresponding to the acquired related information of the second signal according to the second association, then adjust the determined TA according to the TA adjustment value, and finally may send the positioning reference signal to the network device according to the adjusted TA.

Because the positions of the terminals in the cells after reselection are different, the related information of the second signals is also different, so that the TA adjustment value corresponding to the acquired related information of the second signals is determined according to the second association relation, and the determined TA is adjusted according to the TA adjustment value, the adjusted TA is beneficial to ensuring that the TA is as close to (for example, equal to) the TA corresponding to the position of the cells after reselection, and the terminal can send the positioning reference signal by using the proper TA (namely, the adjusted TA).

After cell reselection, the terminal may determine the TA according to the related information of the second signal and the second association relationship between the related information of the second signal and the TA, and further 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 may use the appropriate TA to send the positioning reference signal.

And under the condition that the terminal does not support to determine the adjustment value of the TA according to the related information of the second signal, the network equipment can determine that the terminal does not support to determine the adjustment value of the TA according to the related information of the second signal according to the capability information, and further can select to not configure a second association relation for the terminal.
