Background technique

In order to support direct communication between terminals, a direct link sidelink communication mode is introduced, and a sidelink communication connection can be established between terminals through the PC-5 interface. Based on the sidelink communication connection, the terminal may not directly communicate with the base station, but communicate with the base station through other terminals as a relay.

Taking terminal A and terminal B as an example, after a sidelink communication connection is established between terminal A and terminal B, terminal A can communicate with the base station through terminal B, for example, when terminal A needs to obtain system information, it can send a system information acquisition message to terminal B. Request, terminal B may forward the system information to terminal A after receiving the system information from the base station.

Since the capabilities of different terminals may be different, the obtained system information may also be different. For example, the system information requested by terminal A sending a system information obtaining request is system information that terminal B cannot obtain. In this case, terminal A in the related technology center will wait for terminal B to return the system information or resend the system information acquisition request to terminal B, but because terminal B cannot obtain the system information, waiting for terminal B to return the system information will lead to Terminal A interrupts services based on the requested system information, and re-sending the system information acquisition request to terminal B will cause terminal A to waste signaling overhead.

It should also be understood that the term "and/or" as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

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

For the purpose of brevity and ease of understanding, the terms used herein are "greater than" or "less than", "higher than" or "lower than" when representing a size relationship. But for those skilled in the art, it can be understood that the term "greater than" also covers the meaning of "greater than or equal to", and "less than" also covers the meaning of "less than or equal to"; the term "higher than" covers the meaning of "higher than or equal to". "The meaning of "below" also covers the meaning of "less than or equal to".

Fig. 1 is a schematic flowchart of a method for sending an indication according to an embodiment of the present disclosure. The indication sending method shown in this embodiment can be executed by a first terminal, and the first terminal includes but is not limited to a communication device such as a mobile phone, a tablet computer, a wearable device, a sensor, and an Internet of Things device. The first terminal can communicate with network-side equipment, and the network-side equipment includes but not limited to network-side equipment in communication systems such as 4G, 5G, and 6G, such as base stations and core networks.

The first terminal can also communicate with the second terminal, for example, communicate with the second terminal after establishing a communication connection with the second terminal. The established communication connection can be a sidelink (direct link) communication connection, and the communication method includes but is not limited to unicast , Multicast, Broadcast.

The second terminal may send a system information acquisition request to the first terminal, for requesting the first terminal to send the first system information to the first terminal. The first terminal may receive system information from the network side device, and further, if the received system information includes the first system information, may send the first system information to the second terminal. In this case, the communication manner between the first terminal and the second terminal may include unicast.

For example, the first terminal may receive system information broadcast by the network-side device, or may receive system information unicast by the network-side device (such as on-demand system information), and then when it is determined that the first system information has been obtained, the first terminal The system information is sent to the second terminal. In this case, the second terminal may obtain the first system information without directly communicating with the network side device, specifically, obtain the first system information through the first terminal. In this case, the first terminal may be called As a relay terminal (relay UE (User Equipment, user equipment)), the second terminal may be called a remote terminal (remote UE).

However, due to the different capabilities of different terminals, the obtained system information will also be different. For example, when the second terminal needs to perform certain services, the first system information requested includes the first SIB (System Information Block, system information block) ), but the system information that the first terminal can receive from the network side device only includes the second SIB, and the second SIB is different from the first SIB, so the first terminal cannot send the first SIB to the second terminal.

In this case, if the second terminal continues to wait for the first terminal to return to the first SIB, it will result in that the required service cannot be carried out without the support of the first SIB, which will lead to the termination of the service; if the second terminal sends the first SIB The terminal resends the system information acquisition request for acquiring the first system information. Since the first terminal cannot send the first SIB to the second terminal, communication resources of the second terminal will be wasted. For example, the system information acquisition request carried in the information In the order, it will cause a waste of signaling overhead.

Wherein, the operation of the first terminal to obtain the system information and the operation of the second terminal to request to obtain the first system information can be performed in a connected state, or in a non-connected state (such as an idle state or an inactive state). Make selections as needed.

In addition, the first terminal and the second terminal in all embodiments of the present disclosure are interchangeable. For example, when the first terminal is used as a relay terminal, the second terminal can be used as a remote terminal; for example, when the second terminal is used as a relay terminal , the terminal can be used as a remote terminal. For a certain terminal, it can be used as the first terminal or as the second terminal, which can be determined according to the scene where the terminal is located. For example, if the terminal can directly communicate with the network side device, it can be used as the first terminal. For example, if the terminal cannot directly communicate with the network side device, it can be used as the second terminal.

As shown in Figure 1, the instruction sending method may include the following steps:

In step S101, send indication information to the second terminal, wherein the indication information is used to indicate the manner in which the second terminal obtains the first system information, and the first system information belongs to the System information requested by the first terminal.

In an embodiment, after determining the first system information that the second terminal requests to obtain, the first terminal may send indication information to the second terminal, and use the indication information to instruct the second terminal to obtain the first system information, so that the second terminal The second terminal determines how to obtain the first system information.

Accordingly, regardless of whether the first terminal can return the first system information requested by the second terminal to the second terminal, the indication information can be used to reasonably instruct the second terminal to obtain the first system information, so that the second terminal can obtain the first system information as soon as possible. The information of the first system is obtained, so as to ensure that the business that needs to be performed based on the information of the first system can be carried out smoothly.

For example, the first terminal may first receive a system information acquisition request sent by the second terminal for acquiring the first system information, and then determine whether the first system information can be sent to the second terminal according to the system information.

If the first system information can be sent to the second terminal, the sent indication information may include the first system information, and is used to instruct the second terminal to obtain the first system information directly from the indication information;

If the first system information cannot be sent to the second terminal, the sent instruction information may be used to instruct the first terminal to refuse to send the first system information to the second terminal, so that the second terminal reselects other terminals to establish a communication connection, such as reselecting The other terminal serves as a relay terminal, and further sends a system information acquisition request to the other terminal, so as to acquire the first system information from the other terminal.

Fig. 2 is a schematic flow chart showing another method for sending an indication according to an embodiment of the present disclosure. As shown in Figure 2, the method also includes:

In step S201, the first system information requested by the second terminal is determined according to the system information acquisition request sent by the second terminal.

In an embodiment, the second terminal may send a system information acquisition request to the first terminal, for requesting to acquire the first system information. The first terminal may acquire system information after receiving the system information acquisition request sent by the second terminal, and determine whether the first system information can be acquired during the process of acquiring system information.

It should be noted that, in all embodiments of the present disclosure, the system information that the second terminal needs to obtain can be determined according to the service that the second terminal needs to perform, for example, if it needs to perform positioning services, it can request to obtain system information related to positioning, For example, if a cell reselection service is required, a request may be made to obtain system information related to cell reselection.

Since the services required by the second terminal may change, the system information requested by the second terminal may also change. Therefore, the second terminal is not limited to sending the system information for obtaining the first system information to the first terminal. The information acquisition request, for example, may also send a system information acquisition request for acquiring the second system information to the first terminal when the service changes subsequently.

Fig. 3 is a schematic flow chart showing another method for sending an indication according to an embodiment of the present disclosure. As shown in FIG. 3, the indication information includes first indication information, and sending the indication information to the second terminal includes:

In step S301, in response to not obtaining valid first system information, send first indication information to the second terminal, where the first indication information is used to instruct the first terminal to refuse to send the first system information to the second terminal. The second terminal sends the first system information.

In an embodiment, after receiving the system information acquisition request sent by the second terminal, the first terminal may determine the first system information that the second terminal needs to acquire, and then, in the process of acquiring system information, may try to acquire valid First system information.

If the first terminal fails to obtain valid first system information, it cannot return the first system information to the second terminal. Therefore, the indication information sent to the second terminal may specifically be the first indication information for Instructing the first terminal to refuse to send the first system information to the second terminal.

According to the first indication information, the second terminal may determine that the first terminal refuses to send the first system information to the second terminal, and then obtain the first system information by reselecting another terminal and sending an information obtaining request to the other terminal. According to this, when the first terminal cannot return the first system information to the second terminal, it can avoid the waste of resources caused by the second terminal re-sending the system information acquisition request to the first terminal, and avoid the second terminal from continuing to wait for the first terminal. Returning the first system information causes service interruption (because the second terminal can reselect to other terminals according to the first indication information, so as to obtain the first system information from other terminals as soon as possible to perform services).

Fig. 4 is a schematic flow chart showing another method for sending an indication according to an embodiment of the present disclosure. As shown in FIG. 4, the indication information includes second indication information, and sending the indication information to the second terminal includes:

In step S401, in response to obtaining valid first system information, send second indication information to the second terminal, where the second indication information carries the first system information.

In one embodiment, after receiving the system information acquisition request sent by the second terminal, the first terminal can determine the first system information that the second terminal needs to acquire, and then, in the process of acquiring valid system information, can try to acquire Valid first system information.

If the first terminal successfully obtains the valid first system information, it can return the first system information to the second terminal. Therefore, the indication information sent to the second terminal may specifically be the second indication information. Through the second indication information Carry the first system information. Accordingly, the second terminal may directly obtain the first system information from the second indication information.

In step S501, according to the system information acquisition request sent by the second terminal, determine the first system information requested by the second terminal;

In step S502, obtain valid system information;

In step S503, it is determined whether the first system information exists in the obtained valid system information.

In one embodiment, regarding the method of judging whether the system information is valid (valid), the first terminal may determine whether the acquired system information needs to be updated according to the indication of the network side device (such as the broadcast SIB1), if If there is no need to update, the obtained system information is valid system information. If it needs to be updated, the updated system information can be determined according to the instruction of the network side device, and then the updated system information can be obtained as valid system information. This judging manner is also applicable to judging whether the first system information is valid.

In an embodiment, the second terminal may send a system information acquisition request to the first terminal, for requesting to acquire the first system information. The first terminal first acquires valid system information, and then receives a system information acquisition request sent by the second terminal, and then can determine whether there is first system information requested by the second terminal in the acquired valid system information.

In one embodiment, the obtaining valid system information includes:

Get all valid system information that can be obtained.

At present, when a terminal acquires valid system information, it generally acquires valid system information according to the services it needs to perform, but the system information required by the services it needs to perform is only a part of all the system information that the terminal can obtain.

In order to ensure that the second terminal obtains the requested first system information as soon as possible, when the first terminal obtains valid system information in this embodiment, it is not limited to obtaining the system information required by the business that the first terminal needs to perform. Instead, all valid system information that can be obtained is obtained. Furthermore, after receiving the system information acquisition request sent by the second terminal, it can relatively comprehensively determine whether the first system information requested by the second terminal exists in the effective system information acquired by the first terminal. When the first system information exists in the system information, the first system information may be sent to the second terminal, so that the second terminal obtains the first system information as soon as possible without having to reselect other terminals to obtain the first system information.

Fig. 6 is a schematic flow chart showing another method for sending an indication according to an embodiment of the present disclosure. As shown in FIG. 6, the sending the indication information to the second terminal includes:

In step S601, in response to the fact that the first system information does not exist in the acquired valid system information, send first indication information to the second terminal, where the first indication information is used to indicate the The first terminal refuses to send the first system information to the second terminal.

In an embodiment, after receiving the system information acquisition request sent by the second terminal, the first terminal may determine the first system information that the second terminal needs to acquire, and then determine whether there is First system information.

If there is no valid first system information in the acquired valid system information, then the first system information cannot be returned to the second terminal. Therefore, the indication information sent to the second terminal may specifically be the first indication information , used to instruct the first terminal to refuse to send the first system information to the second terminal.

Fig. 7 is a schematic flow chart showing another method for sending an indication according to an embodiment of the present disclosure. As shown in FIG. 7, the sending the indication information to the second terminal includes:

In step S701, in response to the fact that the first system information exists in the acquired valid system information, send second indication information to the second terminal, where the second indication information carries the first system message.

If there is valid first system information in the acquired valid system information, then the first system information can be returned to the second terminal. Therefore, the indication information sent to the second terminal may specifically be the second indication information, through The second indication information carries the first system information. Accordingly, the second terminal may directly obtain the first system information from the second indication information.

Fig. 8 is a schematic flow chart showing another method for sending an indication according to an embodiment of the present disclosure. As shown in FIG. 8, the indication information includes a first timeout value corresponding to the first timer;

Send the system information acquisition request.

In an embodiment, the first terminal may send the instruction message to the second terminal carrying the first timeout value of the first timer to indicate the way the second terminal obtains the first system information, for example, through the first timeout value The second terminal may be instructed to request a minimum period for acquiring system information, where the minimum period is equal to the first timeout value.

For example, when the indication information carries the first timeout value of the first timer, the first indication information may instruct the second terminal to start the first timer when sending the second system information acquisition request, and when the first timer reaches the first timer Before a timeout value, stop sending the system information acquisition request again.

Correspondingly, the second terminal may start the first timer when sending the system information acquisition request according to the received indication information, and the second terminal may no longer send the system information before the first timer reaches the first timeout value. According to the acquisition request, resource waste caused by the second terminal sending the system information acquisition request too frequently can be avoided.

It should be noted that, before the first timer times out (reaches the first timeout value), the second terminal may stop sending the system information acquisition request for requesting to acquire the first system information. However, when the second system information different from the first system information needs to be requested, before the first timer expires, a system information acquisition request for acquiring the second system information may be sent to the first terminal. Accordingly, on the basis of avoiding frequently sending the system information obtaining request for obtaining the first system information, it can ensure that the system information obtaining request for obtaining the second system information is sent in time.
