The exemplary method can be applied to the terminal and network equipment shown in Figure 1. The method includes at least part of the following content content:

Step 201: The terminal sends capability information to the network device. The capability information indicates parameter information of the positioning signal supported by the terminal.

In the embodiment of this application, positioning signals can be transmitted between the network device and the terminal. Before transmitting the positioning signal, the network device needs to configure the positioning signal for the terminal, and the terminal sends capability information to the network device to inform the network device that it supports Parameter information of the positioning signal, and then the network device can determine the parameter information of the positioning signal supported by the terminal based on the capability information, and complete the positioning signal configured for the terminal.

In some embodiments, the network device includes at least one of a core network device and an access network device. For example, the terminal sends capability information to the access network device, and the capability information also needs to be known to the core network device. The access network device can inform the core network device, or the terminal can directly send the capability information to the core network device. Then the access network equipment and the core network equipment need to consider the terminal's capability information when determining the configuration parameters of the terminal's positioning signal. Afterwards, the core network device sends the determined configuration parameters to the terminal, and then the positioning signal is transmitted between the terminal and the access network device based on the determined configuration parameters.

The parameter information is used to represent the parameters of the positioning signal. It can also be understood that the parameter information refers to the parameters of the positioning signal supported by the terminal, so that the network device can configure a positioning signal that meets the requirements for the terminal based on the parameter information.

Step 202: The network device receives the capability information sent by the terminal. The capability information indicates the parameter information of the positioning signal supported by the terminal.

In the embodiment of this application, the terminal sends capability information to the network device, and the network device can receive the capability information sent by the terminal, and then the network device determines the parameter information of the positioning signal supported by the terminal based on the capability information, so as to base on the determined parameters The information configures the positioning signal for the terminal.

In some embodiments, the positioning signal is used to position the terminal. That is to say, a positioning signal can be transmitted between the terminal and the network device so that the terminal can be positioned based on the positioning signal.

In some embodiments, the positioning signal includes PRS (Positioning Reference Signal) or SRS (Sounding Reference Signal), or the positioning signal can also be other types of signals used for positioning. This application The examples are not limiting.

In the solution provided by the embodiments of this application, the terminal sends capability information to the network device, so that the network device determines the parameter information of the positioning signal supported by the terminal based on the capability information, and then the network device can configure the positioning signal for the terminal based on the parameter information. The application provides a solution for the terminal to report its own capabilities, and the network device can configure the positioning signal for the terminal based on the parameter information of the positioning signal, which improves the applicability of the configured positioning signal.

The embodiment shown in FIG. 2 shows that the terminal indicates the parameter information of the positioning signal it supports through the capability information as an example for explanation. In other embodiments, the parameter information specifically indicates at least one of the duration and transmission interval of the positioning signal supported by the terminal.

The duration of the positioning signal refers to the duration occupied by the positioning signal. The transmission interval of the positioning signal refers to the transmission interval between two transmissions of the positioning signal.

Optionally, the parameter information includes at least one of the following:

(1) The duration of the positioning signal.

Among them, the positioning signal needs to occupy a certain number of symbols to facilitate the transmission of the positioning signal. The duration of the positioning signal can be understood as the number of symbols occupied by the positioning signal. This parameter information includes the number of symbols occupied by the positioning signal, so that the network device can configure the positioning signal for the terminal with the number of symbols occupied by the symbol positioning signal.

(2) The sending interval of positioning signals.

Among them, when the positioning signal is transmitted between the terminal and the network device, the positioning signal can be transmitted every certain period of time to save transmission resources by transmitting the positioning signal at intervals. At this time, the positioning signal transmission interval included in the parameter information is used to save transmission resources. Indicates the interval duration of the positioning signal supported by the terminal, so that the network device can configure the positioning signal for the terminal according to the sending interval of the positioning signal.

In some embodiments, the sending interval of positioning signals refers to the length of time between two adjacent positioning signals.

For example, the positioning signal includes a first positioning signal and a second positioning signal. The transmission interval between the first positioning signal and the second positioning signal refers to the starting position of the first positioning signal and the starting position of the second positioning signal. The length of the interval between. Alternatively, the transmission interval between the first positioning signal and the second positioning signal refers to the interval between the end position of the first positioning signal and the starting position of the second positioning signal.

Among them, the positioning signal supports periodic transmission. If the positioning signal is only sent once in a cycle, the sending interval of the positioning signal depends on the period value or the period value and the number of symbols occupied by the positioning signal. If the positioning signal is sent N times in one cycle, where N>1, then the positioning signal sending interval is the length of the interval between two adjacent sendings in the N sending times.

The embodiment shown in FIG. 2 shows that the terminal indicates the parameter information of the positioning signal it supports through the capability information as an example for explanation. In other embodiments, the parameter information includes specific parameters, and the specific parameters included indicate information about positioning signals supported by the terminal.

Optionally, the parameter information includes at least one of the following:

(1) The number of symbols occupied by the positioning signal.

The positioning signal needs to occupy a certain number of symbols in order to transmit the positioning signal. The parameter information includes the number of symbols occupied by the positioning signal, so that the network device can configure the positioning signal for the terminal with the number of symbols occupied by the positioning signal. It can also be understood that the number of symbols occupied by the positioning signal refers to the duration of the positioning signal.

(2) The period of the positioning signal.

Among them, when transmitting positioning signals between the terminal and the network device, the positioning signals can be transmitted periodically. The terminal indicates the period of the positioning signal supported by the terminal through the period of the positioning signal included in the parameter information, so that the network device configures the positioning signal for the terminal according to the period of the positioning signal.

In addition, within a cycle, the positioning signal can also support repeated transmission. If the number of times the positioning signal is sent in a cycle is 1, the sending interval of the positioning signal is determined by the period value. If the number of times the positioning signal is sent in one cycle is greater than 1, then the parameter information further includes the number of repetitions of the positioning signal described in (3) below and the interval length of the positioning signal described in (4) below.

(3) The number of repetitions of the positioning signal.

Wherein, the number of repetitions of the positioning signal refers to the number of times the positioning signal is repeatedly sent. In some embodiments, the number of repetitions of the positioning signal actually refers to the number of times the positioning signal is repeatedly sent within a cycle.

(4) The interval duration of positioning signals.

The interval duration of positioning signals refers to the duration of the interval between two adjacent positioning signals among the positioning signals sent repeatedly in one cycle.

For example, the positioning signal includes a first positioning signal and a second positioning signal. The interval between the first positioning signal and the second positioning signal refers to the starting position of the first positioning signal and the starting position of the second positioning signal. the length of time. Alternatively, the interval duration between the first positioning signal and the second positioning signal refers to the duration between the end position of the first positioning signal and the starting position of the second positioning signal.

(5) Comb value of positioning signal.

Wherein, the comb value of the positioning signal refers to the sparsity degree of the positioning signal in the frequency domain. The larger the comb value is, the sparser the positioning signal is in the frequency domain, and the smaller the comb value is, the denser the positioning signal is in the frequency domain.

In the solution provided by the embodiment of the present application, the terminal reports at least one parameter of the positioning signal to the network device, which expands the types of parameters for the positioning signal reported by the terminal, and the network device can configure the positioning signal for the terminal based on the parameter information of the positioning signal. , which improves the applicability of positioning signals configured by network equipment for terminals.

The above embodiment describes the parameters included in the parameter information. Specifically, for different parameters, the information included in different parameters is also different. The parameters included in the parameter information are described in detail below.

1. Parameter information includes the number of symbols occupied by the positioning signal.

In some embodiments, the number of symbols occupied by the positioning signal includes a first symbol number, which indicates the minimum number of symbols occupied by the positioning signal supported by the terminal.

In this embodiment of the present application, the first number of symbols indicates the minimum number of symbols occupied by the positioning signal. That is to say, the number of symbols occupied by the positioning signal transmitted between the terminal and the network device is not less than the minimum number of symbols.

For example, if the number of first symbols is 2, the number of symbols occupied by the positioning signal may be 2, 3, 4, 5 or other values not less than 2, which is not limited in the embodiment of this application.

In some other embodiments, the number of symbols occupied by the positioning signal includes at least a second number of symbols, the second number of symbols indicating the number of symbols occupied by the positioning signal supported by the terminal.

In this embodiment of the present application, the second symbol number indicates the number of symbols occupied by the positioning signal supported by the terminal. It can also be understood that one second symbol number indicates the number of symbols occupied by the positioning signal supported by the terminal, and multiple second symbols The number indicates the number of multiple symbols occupied by the positioning signal supported by the terminal.

For example, if the number of at least one second symbol includes 2, 4, 6, and 8, it means that the number of symbols occupied by the positioning signal supported by the terminal includes four situations: 2, 4, 6, and 8, and other than 2, 4, 6, and 8. Values such as 1, 3, 5, 7, 9, 10, etc. are the number of symbols occupied by positioning signals that are not supported by the terminal.

It should be noted that the embodiment of the present application takes as an example the number of symbols of different types included in the number of symbols occupied by the positioning signal. In another embodiment, there is a corresponding relationship between the number of symbols of different types and the subcarrier spacing.

In some embodiments, the first number of symbols and/or the second number of symbols is the number of symbols corresponding to the first subcarrier interval.

In this embodiment of the present application, there is a corresponding relationship between the number of symbols and the subcarrier spacing. There is the following correspondence between the number of symbols occupied by the positioning signal and the first subcarrier spacing:

(1) The number of first symbols is the number of symbols corresponding to the first subcarrier interval.

(2) The number of second symbols is the number of symbols corresponding to the first subcarrier spacing.

(3) The first number of symbols and the second number of symbols are the number of symbols corresponding to the first subcarrier spacing.

In some embodiments, the period of the positioning signal includes a first period indicating a maximum period of the positioning signal supported by the terminal.

In this embodiment of the present application, the period of the positioning signal indicates the maximum period value of the period supported by the terminal. That is to say, the period of transmitting the positioning signal between the terminal and the network device cannot be greater than the maximum period value.

For example, the first period is 4 time slots, 8 time slots...10240 time slots, 20480 time slots or other numbers of time slots, or the first period is 4 milliseconds (ms), 8ms, 16ms, 32ms...10240ms, 20480ms or other number of milliseconds, which are not limited in the embodiments of this application.

In other embodiments, the period of the positioning signal includes at least one second period, the second period being indicative of the period of the positioning signal supported by the terminal.

In this embodiment of the present application, the second period indicates the period of the positioning signal supported by the terminal. It can also be understood that one second period indicates one period of the positioning signal supported by the terminal, and multiple second periods indicate the positioning signal supported by the terminal. of multiple cycles.

For example, at least one second cycle includes 4 time slots, 8 time slots, and 16 time slots, which means that the positioning signal cycle supported by the terminal includes three situations: 4 time slots, 8 time slots, and 16 time slots. , and the periods other than 4 time slots, 8 time slots, and 16 time slots are all periods of positioning signals that are not supported by the terminal.

It should be noted that the period of the positioning signal in the embodiment of the present application is actually related to the interval length and the number of repetitions of the positioning signal.

In some embodiments, the interval duration of the positioning signal is the ratio of the period of the positioning signal to the number of repetitions.

For example, if the interval length is defined as the starting position of the first positioning signal to the starting position of the second positioning signal, if the number of repetitions is 1, then the interval length of the positioning signal can be equal to the period; if the number of repetitions is greater than 1, then the positioning The interval duration of the signal can be equal to the ratio of the period to the number of repetitions, or the interval duration of the positioning signal has nothing to do with the ratio of the period to the number of repetitions, for example, multiple repetitions are not evenly distributed within a period.

Or, if the interval length is defined as the end position of the first positioning signal to the starting position of the second positioning signal, when the number of repetitions is 1, since the period includes the number of symbols occupied by the positioning signal, the period of the positioning signal is actually greater than The interval between positioning signals.

It should be noted that the embodiment of the present application takes as an example that the periods of the positioning signal include different types of periods. In another embodiment, there is a corresponding relationship between different types of periods and subcarrier intervals.

In some embodiments, the first period and/or the second period are period values corresponding to the first subcarrier spacing.

In this embodiment of the present application, there is a corresponding relationship between the period value and the first subcarrier spacing. There is the following correspondence between the period value of the positioning signal and the first subcarrier spacing:

(1) The first period is the period value corresponding to the first subcarrier interval.

(2) The second period is the period value corresponding to the first subcarrier interval.

(3) The first period and the second period are period values corresponding to the first subcarrier interval.

The first subcarrier spacing is 15 kHz (kilohertz), 30 kHz, 60 kHz, 120 kHz or other values, which is not limited in the embodiment of this application.

3. Parameter information includes the number of repetitions of the positioning signal.

In some embodiments, the number of repetitions of the positioning signal includes a first number of repetitions, which indicates a minimum number of repetitions of the positioning signal supported by the terminal.

Optionally, the number of repetitions of the positioning signal actually refers to the number of repetitions within one cycle of the positioning signal.

In this embodiment of the present application, the first number of repetitions indicates the minimum number of repetitions of the positioning signal. That is to say, the number of repetitions of the positioning signal transmitted between the terminal and the network device is not less than the minimum number of repetitions.

For example, if the first number of repetitions is 1, then the number of repetitions of the positioning signal may be 1, 2, 3 or other values not less than 1, which are not limited in the embodiments of this application.

In some other embodiments, the number of repetitions of the positioning signal includes at least a second number of repetitions, the second number of repetitions indicating the number of repetitions of the positioning signal of the terminal.

In the embodiment of the present application, the second number of repetitions indicates the number of repetitions of the positioning signal supported by the terminal. It can also be understood that one second number of repetitions indicates one number of repetitions of the positioning signal supported by the terminal, and multiple second number of repetitions indicate The terminal supports multiple repetitions of the positioning signal.

For example, if at least one second repetition number includes 1, 2, and 3, it means that the number of repetitions of the positioning signal supported by the terminal includes 1, 2, and 3, and all values other than 1, 2, and 3 are not supported by the terminal. The number of repetitions of the positioning signal.

It should be noted that the embodiment of the present application takes as an example that the number of repetitions of the positioning signal includes different types of repetition times. In another embodiment, there is a corresponding relationship between the number of repetitions of different types and the subcarrier spacing.

In some embodiments, the first number of repetitions and/or the second number of repetitions is the number of repetitions corresponding to the first subcarrier interval.

In the embodiment of the present application, there is a corresponding relationship between the number of repetitions and the subcarrier spacing. There is a corresponding relationship between the number of repetitions of the positioning signal and the first subcarrier interval:

(1) The first number of repetitions is the number of repetitions corresponding to the first subcarrier interval.

(2) The second number of repetitions is the number of repetitions corresponding to the first subcarrier interval.

(3) The first number of repetitions and the second number of repetitions are the number of repetitions corresponding to the first subcarrier interval.

4. Parameter information includes the interval duration of positioning signals.

In some embodiments, the interval duration of the positioning signal includes a first interval duration indicating a maximum interval duration between positioning signals supported by the terminal.

In this embodiment of the present application, the interval duration of the positioning signal indicates the maximum interval duration between positioning signals supported by the terminal. That is to say, the interval duration for transmitting positioning signals between the terminal and the network device cannot be greater than the maximum interval duration.

For example, the first interval duration is 4 time slots, 8 time slots, or other number of time slots, which is not limited in the embodiment of this application.

In some other embodiments, the interval duration of the positioning signal includes at least one second interval duration, the second interval duration indicating the interval duration between positioning signals supported by the terminal.

In this embodiment of the present application, the second interval duration indicates an interval duration between positioning signals supported by the terminal. It can also be understood that a second interval duration indicates an interval duration between positioning signals supported by the terminal, and multiple third interval durations indicate an interval duration between positioning signals supported by the terminal. The second interval duration indicates multiple interval durations between positioning signals supported by the terminal.

For example, if at least one second interval duration includes 2 time slots, 4 time slots, and 8 time slots, it means that the interval duration between positioning signals supported by the terminal includes 2 time slots, 4 time slots, and 8 time slots. There are three situations of slots, and the interval lengths other than 2 time slots, 4 time slots and 8 time slots are all the interval lengths between positioning signals that are not supported by the terminal.
