[0036] 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.

[0037] Figure 1 This is a schematic flowchart illustrating an information transmission method according to an embodiment of the present disclosure. The information transmission method shown in this embodiment can be applied to a first terminal, which includes, but is not limited to, electronic devices such as mobile phones, tablets, wearable devices, sensors, and IoT devices. The first terminal can communicate with a base station as a user equipment, and the base station includes, but is not limited to, 4G base stations, 5G base stations, and 6G base stations.

[0038] The first terminal can also communicate with other terminals, such as the second terminal. It can establish a sidelink (also called a secondary link or side link) with the second terminal. The interface of the sidelink can be a PC5 interface. The first terminal communicates with the second terminal through the sidelink. The first terminal and the second terminal need to communicate according to a specific Quality of Service (QoS) standard, such as transmitting signaling and data. The relevant parameters of QoS can be used for QoS flow.

[0039] In one embodiment, the first terminal and the second terminal can determine their relative spatial relationship. For example, the first terminal, as the initiating terminal for determining the relative spatial relationship, can determine the position, distance, angle, etc., of the second terminal relative to the first terminal, and the second terminal can also determine the position, distance, angle, etc., of the first terminal relative to the second terminal. The process of determining the relative spatial relationship can be referred to as relative positioning, ranging or sensing, ranging-based service, or sidelink positioning.

[0040] Taking the determination of the position of the second terminal relative to the first terminal by the first terminal as an example.

[0041] The first terminal can determine the relative angle of the second terminal with respect to the first terminal. The relative angle includes, but is not limited to, the angle of arrival (AOA) and the angle of departure (AOD). AOA represents the angle between the antenna of the first terminal's signal receiver and the reference signal received from the second terminal, and AOD represents the angle between the antenna of the first terminal's signal transmitter and the reference signal transmitted to the second terminal.

[0042] The first terminal can determine the relative distance between the second terminal and the first terminal, for example, based on the reception time of the reference signal received from the second terminal, the transmission time of the reference signal, and the transmission speed of the reference signal.

[0043] Then, based on the relative angle and relative speed, the position of the second terminal relative to the first terminal can be determined.

[0044] During the process of determining the relative spatial relationship, the first terminal and the second terminal can receive and send signals through the sidelink.

[0045] However, the determination of relative spatial relationships between terminals is subject to specific service quality requirements based on the specific scenario. The service quality requirements for determining relative spatial relationships between terminals may differ from those for other communication processes between terminals (such as transmitting signaling and data). Therefore, even if the terminals determine the required service quality for communication after establishing a sidelink, the service quality may not necessarily meet the service quality required for determining relative spatial relationships between terminals.

[0046] like Figure 1 As shown, the information sending method may include the following steps:

[0047] In step S101, in response to determining the relative spatial relationship with the second terminal, service quality information determining the relative spatial relationship is sent to the second terminal.

[0048] In one embodiment, the relative spatial relationship includes at least one of the following:

[0049] Relative position, relative distance, relative angle, relative speed.

[0050] In one embodiment, when the first terminal needs to determine a relative spatial relationship with the second terminal, it can send service quality information (QoS) information for determining the relative spatial relationship to the second terminal. Accordingly, the second terminal can determine the relative spatial relationship with the first terminal based on the received QoS information, for example, determining a configuration for sending a reference signal to the first terminal based on the QoS information, and / or measuring the reference signal sent by the first terminal based on the QoS information, so that the relative spatial relationship determined by the first terminal meets the required QoS.

[0051] In one embodiment, the first terminal may send the quality of service information to the second terminal only when it is necessary to determine a specified relative spatial relationship with the second terminal. For example, the first terminal may send the quality of service information to the second terminal only when it is necessary to determine the relative position. When it is necessary to determine the relative speed, it is not necessary to send the quality of service information to the second terminal. The specified relative spatial relationship can be set as needed.

[0052] In one embodiment, the service quality information includes at least one of the following:

[0053] Precision information on relative spatial relationships;

[0054] The first response time for sending a reference signal to the first terminal to determine the relative spatial relationship;

[0055] The second response time for sending the result information determining the relative spatial relationship to the first terminal;

[0056] Determine the upper limit of the distance for relative spatial relationships.

[0057] In one embodiment, the quality of service information may include precision information of relative spatial relationships. Taking the determination of relative distance as an example, the second terminal can determine the distance between the first terminal and the second terminal, and then send the determined distance as the result information to the first terminal. In determining the distance between the first terminal and the second terminal, it is necessary to determine it according to the precision information. For example, if the precision information is 1 cm, then the precision of the determined distance needs to reach 1 cm. Furthermore, the second terminal needs to perform relevant measurements on the reference signal sent by the first terminal according to the requirements of the precision information.

[0058] In one embodiment, the quality of service information may include a first response time for the second terminal to send a reference signal to the first terminal to determine a relative spatial relationship. Taking the determination of relative distance as an example, in order for the first terminal to determine the position of the second terminal relative to the first terminal, the second terminal may send a reference signal to the first terminal. For example, if the first response time is 10 milliseconds, then after receiving the request from the first terminal to determine the relative position, the second terminal needs to send the reference signal to the first terminal within 10 milliseconds so that the first terminal can determine the relative position in a timely manner.

[0059] In one embodiment, the quality of service information may include a second response time for the second terminal to send the result information of determining the relative spatial relationship to the first terminal. Taking the determination of relative distance as an example, the second terminal can determine the position of the second terminal relative to the first terminal, and then send the determined position as the result information to the first terminal. For example, if the second response time is 100 milliseconds, then after receiving the request from the first terminal to determine the relative position, the second terminal needs to send the determined position to the first terminal within 100 milliseconds so that the first terminal can obtain the position determined by the second terminal in a timely manner.

[0060] In one embodiment, the quality of service information may include a distance upper limit for determining the relative spatial relationship. This distance upper limit can be set as needed or estimated by the first terminal; it can be understood as the maximum possible distance between the first and second terminals when determining their relative spatial relationship. During the process of determining the relative spatial relationship, the second terminal needs to send a reference signal to the first terminal. To ensure the transmitted signal is well received by the first terminal, the second terminal can determine the transmission power of the reference signal based on the distance upper limit; for example, a higher distance upper limit results in a higher transmission power.

[0061] Figure 2 This is a schematic flowchart illustrating another information sending method according to embodiments of the present disclosure. Figure 2 As shown, in some embodiments of this disclosure, the method further includes:

[0062] In step S201, the service applied to determine the relative spatial relationship with the second terminal is determined;

[0063] In step S202, the service quality information is determined based on the service.

[0064] In one embodiment, the relative spatial relationship determined between the first terminal and the second terminal generally needs to be applied to specific communication services, such as multimedia sharing, item finding, smart home control, etc. The service quality required by different services may be different, so the service quality information can be determined according to the service.

[0065] For example, if service A requires low latency, when relative location is needed, the first terminal needs to determine the relative location quickly. Therefore, the first response time determined by the first terminal can be short, so that the second terminal can send a reference signal to the first terminal as soon as possible, so that the first terminal can determine the relative location as quickly as possible and meet the low latency requirement of service A.

[0066] Figure 3 This is a schematic flowchart illustrating yet another information transmission method according to embodiments of the present disclosure. Figure 3 As shown, in some embodiments of this disclosure, the method further includes:

[0067] In step S301, configuration information is sent to the second terminal, wherein the configuration information is used for the second terminal to determine the configuration for sending a reference signal for determining the relative spatial relationship to the first terminal.

[0068] In one embodiment, the configuration information includes at least one of the following:

[0069] Bandwidth information, periodic information, time-domain density information, and frequency-domain density information.

[0070] In one embodiment, the second terminal sends a reference signal to the first terminal, which needs to be sent according to certain configurations. In this embodiment, the first terminal can send configuration information to the second terminal so that the second terminal can determine the configuration for sending the reference signal to the first terminal. That is, the configuration information sent by the first terminal to the second terminal can be used as a reference by the second terminal. The second terminal can determine the configuration for sending the reference signal according to the configuration information. Alternatively, the second terminal can determine the configuration for sending the reference signal according to its own needs instead of according to the configuration information.

[0071] For example, if the configuration information includes bandwidth information, the second terminal can determine the bandwidth for sending the reference signal. For instance, if the bandwidth is 10 Mbps, and the sidelink bandwidth for communication between the first and second terminals is 20 Mbps, then the second terminal can select 10 Mbps of this 20 Mbps bandwidth to send the reference signal. Of course, as mentioned earlier, the second terminal can also choose not to determine the reference signal configuration based on the configuration information. For example, if the second terminal itself requires 15 Mbps bandwidth for communication, then it can select 15 Mbps of this 20 Mbps bandwidth to send the reference signal.

[0072] For example, if the configuration information includes period information, the second terminal can determine the period of the transmitted reference signal. If the configuration information includes time-domain density information, the second terminal can determine the time-domain density of the transmitted reference signal. If the configuration information includes frequency-domain density information, the second terminal can determine the frequency-domain density of the transmitted reference signal.

[0073] Figure 4 This is a schematic flowchart illustrating yet another information transmission method according to embodiments of the present disclosure. Figure 4 As shown, in some embodiments of this disclosure, the method further includes:

[0074] In step S401, the service applied to determining the relative spatial relationship with the second terminal is determined;

[0075] In step S402, the configuration information is determined according to the service.

[0076] In one embodiment, the relative spatial relationship determined between the first terminal and the second terminal generally needs to be applied to specific communication services, such as multimedia sharing, item finding, smart home control, etc. The communication configuration required by different services may be different, so the configuration information can be determined according to the service.

[0077] For example, if service A requires frequent acquisition of relative position, then the first terminal needs to frequently determine the relative position, and the determination period can be relatively short. This allows the second terminal to send reference signals to the first terminal more frequently, so that the first terminal can frequently determine the relative position and meet the frequency requirement of service A for acquiring relative position.

[0078] For example, if service B requires a high accuracy in obtaining the relative position, then the first terminal needs to obtain reference signals in more time and frequency domains, thereby determining that the time and frequency densities in the configuration information can be relatively large, so that the second terminal can send reference signals to the first terminal with a large time and frequency density, so that the first terminal can determine the relative position relatively accurately and meet the requirements of service B for obtaining the accuracy of the relative position.

[0079] Figure 5A This is a schematic flowchart illustrating yet another information transmission method according to embodiments of the present disclosure. Figure 5A As shown, in some embodiments of this disclosure, sending the quality of service information determining the relative spatial relationship to the second terminal includes:

[0080] In step S501, during the process of establishing a sidelink with the second terminal, the quality of service information is sent to the second terminal.

[0081] In one embodiment, the first terminal can communicate with the second terminal via a sidelink. During the process of establishing the sidelink with the second terminal, the first terminal can send quality of service information to the second terminal.

[0082] Figure 5B This is a schematic flowchart illustrating another method for sending quality of service information during the establishment of a secondary link, according to an embodiment of the present disclosure.

[0083] In one embodiment, the first terminal and the second terminal can determine the destination identifier (e.g., Layer-2 ID) for receiving based on application information. If the direct communication request sent by the first terminal contains the destination identifier, the second terminal can receive the signal sent by the first terminal and perform parsing and identification. However, if the direct communication request sent by the first terminal does not contain the destination identifier, the second terminal will not perform parsing and identification even if it receives the signal sent by the first terminal.

[0084] Next, the first terminal, as the initiator of establishing the sidelink, can receive application information provided by its own application layer and then send a direct communication request to the second terminal, such as by broadcast, unicast, or multicast, to request the establishment of a sidelink with the second terminal.

[0085] Next, the first terminal and the second terminal can perform a security establishment process, during which the quality of service information can be sent to the second terminal.

[0086] After a secure connection is established, the second terminal can send a Direct Communication Accept to the first terminal, for example, via unicast. The first terminal can then confirm that the sidelink has been established.

[0087] Next, the first terminal and the second terminal can communicate through the established sidelink, for example, at the access layer of the sidelink, and complete the process of determining the relative spatial relationship between the first terminal and the second terminal based on the service quality information.

[0088] Figure 6 This is a schematic flowchart illustrating yet another information transmission method according to embodiments of the present disclosure. Figure 6 As shown, in some embodiments of this disclosure, sending the quality of service information determining the relative spatial relationship to the second terminal includes:

[0089] In step S601, after establishing a sidelink with the second terminal, the quality of service information is sent to the second terminal through the sidelink.

[0090] In one embodiment, the first terminal can communicate with the second terminal via a sidelink. After establishing the sidelink with the second terminal, the first terminal can send quality of service information to the second terminal via the established sidelink, for example, by sending the quality of service information to the second terminal via a PC5 RRC (Radio Resource Control) message.

[0091] Figure 7 This is a schematic flowchart illustrating a relationship determination method according to an embodiment of the present disclosure. The relationship determination method shown in this embodiment can be applied to a second terminal, which includes, but is not limited to, electronic devices such as mobile phones, tablets, wearable devices, sensors, and IoT devices. The second terminal can communicate with a base station as a user equipment, and the base station includes, but is not limited to, 4G base stations, 5G base stations, and 6G base stations.

[0092] The second terminal can also communicate with other terminals, such as the first terminal. It can establish a sidelink with the first terminal, and the interface of the sidelink can be a PC5 interface. Then, it can communicate with the first terminal through the sidelink.

[0093] In one embodiment, the first terminal and the second terminal can determine their relative spatial relationship. For example, the first terminal, as the initiating terminal for determining the relative spatial relationship, can determine the position, distance, angle, etc. of the second terminal relative to the first terminal, and the second terminal can also determine the position, distance, angle, etc. of the first terminal relative to the second terminal. The process of determining the relative spatial relationship can be referred to as relative positioning, ranging or sensing, ranging or sensing-based services, or secondary link positioning.

[0094] Taking the determination of the position of the second terminal relative to the first terminal by the first terminal as an example.

[0095] The first terminal can determine the relative angle of the second terminal with respect to the first terminal. The relative angle includes, but is not limited to, the angle of arrival and the angle of departure. AOA represents the angle between the antenna of the first terminal's signal receiver and the reference signal received from the second terminal, and AOD represents the angle between the antenna of the first terminal's signal transmitter and the reference signal transmitted to the second terminal.

[0096] The first terminal can determine the relative distance between the second terminal and the first terminal. For example, the second terminal sends a reference signal to the first terminal, and the first terminal determines the distance based on the reception time of the reference signal, the transmission time of the reference signal, and the transmission speed of the reference signal.

[0097] Then, based on the relative angle and relative speed, the position of the second terminal relative to the first terminal can be determined.

[0098] During the process of determining the relative spatial relationship, the first terminal and the second terminal can receive and send signals through the sidelink.

[0099] However, the determination of relative spatial relationships between terminals is subject to specific service quality requirements based on the specific scenario. The service quality requirements for determining relative spatial relationships between terminals may differ from those for other communication processes between terminals (such as transmitting signaling and data). Therefore, even if the terminals determine the required service quality for communication after establishing a sidelink, the service quality may not necessarily meet the service quality required for determining relative spatial relationships between terminals.

[0100] like Figure 7 As shown, the relationship determination method may include the following steps:

[0101] In step S701, the service quality information determining the relative spatial relationship sent by the first terminal is received;

[0102] In step S702, the relative spatial relationship is determined based on the service quality information.

[0103] In one embodiment, the relative spatial relationship includes at least one of the following:

[0104] Relative position, relative distance, relative angle.

[0105] In one embodiment, when the first terminal needs to determine a relative spatial relationship with the second terminal, it can send service quality information (QoS) information for determining the relative spatial relationship to the second terminal. Accordingly, the second terminal can determine the relative spatial relationship with the first terminal based on the received QoS information, for example, determining the configuration for sending a reference signal to the first terminal based on the QoS information, and / or measuring the reference signal sent by the first terminal based on the QoS information, so that the relative spatial relationship determined by the first terminal meets the required QoS.

[0106] In one embodiment, the service quality information includes at least one of the following:

[0107] Precision information on relative spatial relationships;

[0108] The first response time for sending a reference signal to the first terminal to determine the relative spatial relationship;

[0109] The second response time for sending the result information determining the relative spatial relationship to the first terminal;

[0110] Determine the upper limit of the distance for relative spatial relationships.

[0111] In one embodiment, the quality of service information may include precision information of relative spatial relationships. Taking the determination of relative distance as an example, the second terminal can determine the distance between the first terminal and the second terminal, and then send the determined distance as the result information to the first terminal. In determining the distance between the first terminal and the second terminal, it is necessary to determine it according to the precision information. For example, if the precision information is 1 cm, then the precision of the determined distance needs to reach 1 cm. Furthermore, the second terminal needs to perform relevant measurements on the reference signal sent by the first terminal according to the requirements of the precision information.

[0112] Figure 8 This is a schematic flowchart illustrating another relationship determination method according to embodiments of the present disclosure. Figure 8 As shown, in some embodiments of this disclosure, the method further includes:

[0113] In step S801, in response to the quality of service information including the first response time, a priority for sending the reference signal and other information to the first terminal is determined based on the first response time.

[0114] In one embodiment, the quality of service information may include a first response time for the second terminal to send a reference signal to the first terminal to determine a relative spatial relationship. Taking the determination of relative distance as an example, in order for the first terminal to determine the position of the second terminal relative to the first terminal, the second terminal may send a reference signal to the first terminal. For example, if the first response time is 10 milliseconds, then after receiving the request from the first terminal to determine the relative position, the second terminal needs to send the reference signal to the first terminal within 10 milliseconds so that the first terminal can determine the relative position in a timely manner.

[0115] However, when the second terminal needs to send a reference signal, there may be other information that needs to be sent. Therefore, the second terminal can determine the priority of the reference signal and other information.

[0116] In one embodiment, if the reference signal has a higher priority, it can be sent first; if other information has a higher priority, it can be sent first and then the reference signal.

[0117] In one embodiment, when both a reference signal and other information need to be transmitted, the second terminal can set a higher priority for the reference signal to ensure that the reference signal is transmitted first.

[0118] Figure 9 This is a schematic flowchart illustrating yet another relationship determination method according to embodiments of the present disclosure. Figure 9 As shown, in some embodiments of this disclosure, the method further includes:

[0119] In step S901, in response to the service quality information including the second response time, the priority for sending the result information and other information to the first terminal is determined based on the second response time.

[0120] In one embodiment, the quality of service information may include a second response time for the second terminal to send the result information of determining the relative spatial relationship to the first terminal. Taking the determination of relative distance as an example, the second terminal can determine the position of the second terminal relative to the first terminal, and then send the determined position as the result information to the first terminal. For example, if the second response time is 100 milliseconds, then after receiving the request from the first terminal to determine the relative position, the second terminal needs to send the determined position to the first terminal within 100 milliseconds so that the first terminal can obtain the position determined by the second terminal in a timely manner.

[0121] However, when the second terminal needs to send result information, there may be other information that needs to be sent. Therefore, the second terminal can determine the priority between the result information and other information.

[0122] In one embodiment, if the result information has a higher priority, the reference signal can be sent first; if other information has a higher priority, the other information can be sent first, followed by the result information.

[0123] In one embodiment, when both result information and other information need to be sent, the second terminal can set a higher priority for the result information, thereby ensuring that the result information is sent first.

[0124] Figure 10 This is a schematic flowchart illustrating yet another relationship determination method according to embodiments of the present disclosure. Figure 10 As shown, in some embodiments of this disclosure, the method further includes:

[0125] In step S1001, in response to the quality of service information including the distance limit, the transmission power of the signal sent to the first terminal during the process of determining the relative spatial relationship with the first terminal is determined according to the distance limit;

[0126] In step S1002, the reference signal and / or the result information are sent to the first terminal according to the power.

[0127] In one embodiment, the service quality information may include a distance upper limit for determining the relative spatial relationship, wherein the distance upper limit may be set as needed or estimated by the first terminal, and can be understood as the maximum possible distance between the first terminal and the second terminal when the relative spatial relationship is determined.

[0128] In the process of determining the relative spatial relationship, the second terminal needs to send a reference signal to the first terminal. In order to ensure that the sent signal is well received by the first terminal, the second terminal can determine the transmission power of the reference signal based on the upper limit of the distance. For example, the higher the upper limit of the distance, the greater the transmission power. Then, the second terminal sends the reference signal and / or result information to the first terminal according to the power.

[0129] Figure 11 This is a schematic flowchart illustrating yet another relationship determination method according to embodiments of the present disclosure. Figure 11 As shown, in some embodiments of this disclosure, the method further includes:

[0130] In step S1101, a reference signal configuration for determining the relative spatial relationship is determined to be sent to the first terminal based on the configuration information sent by the first terminal.

[0131] In one embodiment, the configuration information includes at least one of the following:

[0132] Bandwidth information, periodic information, time-domain density information, and frequency-domain density information.

[0133] In one embodiment, the second terminal sends a reference signal to the first terminal, which needs to be sent according to certain configurations. In this embodiment, the first terminal can send configuration information to the second terminal so that the second terminal can determine the configuration for sending the reference signal to the first terminal. That is, the configuration information sent by the first terminal to the second terminal can be used as a reference by the second terminal. The second terminal can determine the configuration for sending the reference signal according to the configuration information. Alternatively, the second terminal can determine the configuration for sending the reference signal according to its own needs instead of according to the configuration information.

[0134] For example, if the configuration information includes bandwidth information, the second terminal can determine the bandwidth for sending the reference signal. For instance, if the bandwidth is 10 Mbps, and the sidelink bandwidth for communication between the first and second terminals is 20 Mbps, then the second terminal can select 10 Mbps of this 20 Mbps bandwidth to send the reference signal. Of course, as mentioned earlier, the second terminal can also choose not to determine the reference signal configuration based on the configuration information. For example, if the second terminal itself requires 15 Mbps bandwidth for communication, then it can select 15 Mbps of this 20 Mbps bandwidth to send the reference signal.

[0135] For example, if the configuration information includes period information, the second terminal can determine the period of the transmitted reference signal. If the configuration information includes time-domain density information, the second terminal can determine the time-domain density of the transmitted reference signal. If the configuration information includes frequency-domain density information, the second terminal can determine the frequency-domain density of the transmitted reference signal.
