[0056] Figure 9 A structural block diagram of an electronic device according to an embodiment of the present disclosure is shown. Detailed Implementation

[0057] The exemplary implementation will now be described more fully with reference to the accompanying drawings.

[0058] It should be noted that the example implementation can be implemented in many forms and should not be construed as being limited to the examples set forth herein.

[0059] Through research, the inventors discovered that existing spectrum enhancement schemes are generally used independently, meaning that secondary users can only use one access method and cannot choose from multiple access methods. Furthermore, existing spectrum enhancement schemes do not take into account the impact of the communication status information of the primary user's communication system on the communication between primary and secondary users.

[0060] To address the aforementioned issues, this application discloses a communication method, apparatus, device, and medium, applicable to a communication system comprising primary and secondary users, wherein the time-frequency resources of the primary user and the secondary user are identical.

[0061] It should be noted that, in this embodiment of the disclosure, the primary and secondary users can be in the same communication system, or the primary and secondary users can belong to different communication systems.

[0062] like Figure 1 As shown, primary user 101 and secondary user 102 belong to the same communication system. Primary user 101 sends broadcast messages through the communication system, and the broadcast messages include access indication information to indicate the access method of the secondary user. Figure 1 There can be multiple users who can receive broadcast messages (not shown in the figure). Once the number of users using the same time and frequency resources in this communication system reaches a preset number, other users using the same time and frequency resources may no longer be allowed to access the system.

[0063] exist Figure 1 In this process, secondary user 102 can select an access method to access the communication system based on the received broadcast information. Before this, secondary user 102 can only receive information from the communication system and cannot transmit data through the communication system.

[0064] like Figure 2 As shown, primary user 201 and secondary user 202 belong to different communication systems. Primary user 201 sends broadcast messages through its communication system. The broadcast messages include access indication information to indicate the access method of secondary users.

[0065] exist Figure 2 In this process, secondary user 202 can select an access method to access the secondary communication system based on the received broadcast information. Before that, secondary user 202 cannot transmit data through the secondary communication system.

[0066] It should also be noted that in this embodiment, the difference between the primary user and the secondary user may be due to different user levels or different times of access to the communication system.

[0067] Furthermore, the users (including primary and secondary users) in this disclosure embodiment can be user terminals (UEs), including but not limited to mobile phones, tablets, laptops, vehicle communication devices, drones, communication modules on drones, remote-controlled aircraft, aircraft, small aircraft, vehicles, RSUs, wireless sensors, internet cards, IoT terminals, RFID terminals, NB-IoT terminals, MTC (Machine Type Communication) terminals, eMTC (enhanced MTC) terminals, data cards, internet cards, vehicle communication devices, low-cost mobile phones, low-cost tablets, and other wireless communication devices.

[0068] Figure 3This diagram illustrates a communication method flowchart according to an embodiment of the present disclosure. This embodiment is applied to a communication system containing primary and secondary users, where the time-frequency resources of the primary user and the secondary user are the same, and the primary and secondary users belong to the same communication system. The structure is as shown above. Figure 1 As shown.

[0069] like Figure 3 As shown, the communication method provided in this embodiment includes steps S302-S306.

[0070] S302, the communication system where the primary user is located determines the access instruction information for the secondary user based on the communication status information.

[0071] In some embodiments, the access indication information includes whether the secondary user is allowed to access the communication system while communicating. If the secondary user is allowed to access the communication system while communicating, the access indication information also includes the secondary user's access method.

[0072] In some embodiments, the communication status information of the communication system includes the type of service being performed by the communication system, and the access indication information may be determined based on the type of service being performed by the communication system to which the primary user is located.

[0073] When the primary user's communication system is performing high-reliability, low-latency services, it can instruct secondary users not to access the system. When the primary user's communication system is not performing communication or is performing short message services, it can instruct secondary users to use padding spectrum sharing. If the primary user's communication system is performing ordinary data service transmission, it can instruct secondary users to use padding spectrum sharing or non-orthogonal multiple access methods to access the system.

[0074] S304, the communication system where the main user is located will add the access indication information to the broadcast message of the communication system for broadcast.

[0075] In some embodiments, the access method recorded in the access indication information of the secondary user may include non-orthogonal multiple access and spectrum sharing, that is, the access method recorded in the access indication information of the secondary user may be non-orthogonal multiple access or spectrum sharing, or other access methods.

[0076] In some embodiments, the access method recorded in the access indication information of the secondary user may also be one of the following access methods: padding spectrum sharing, filling spectrum sharing, power domain non-orthogonal multiple access, and code domain non-orthogonal multiple access.

[0077] In some embodiments, the broadcast message may be a base station MIB message or a Wi-Fi Becon message.

[0078] S306, the secondary user determines the access method to the communication system from multiple preset access methods according to the access instruction information. The multiple preset access methods include non-orthogonal multiple access and spectrum sharing.

[0079] In some embodiments, if the access instruction information allows a secondary user to access the communication system while communicating with the main system, the user may select the access method recorded in the access instruction information to access the communication system.

[0080] Since the access method recorded in the indication information can be a primary category such as non-orthogonal multiple access or spectrum sharing, or a secondary category such as padding spectrum sharing, filling spectrum sharing, power domain non-orthogonal multiple access, or code domain non-orthogonal multiple access, the step of selecting the access method in S306 above can be either to directly select a secondary category access method, or to select a primary category access method and then specifically determine and select a secondary category access method under the primary category.

[0081] In one embodiment, the access method described in S304 may be one of the access methods in the first-level classification mentioned above. After receiving the broadcast message from the communication system, S306 may further include: calculating the interference temperature based on the received base station indication and base station signal strength, and then selecting one of the following access methods to access the communication system based on the access indication information and the interference temperature: under-pad spectrum sharing, filling spectrum sharing, power domain non-orthogonal multiple access, and code domain non-orthogonal multiple access.

[0082] If a secondary user supports multiple access methods, upon receiving a broadcast message from the base station, it needs to calculate the interference temperature based on the received base station indication and signal strength. Then, based on the magnitude of the interference temperature, it determines the secondary access category. When the interference temperature is below a certain threshold, the secondary user can choose under-shielded spectrum sharing access; when it exceeds a certain threshold, it chooses non-orthogonal multiple access.

[0083] In some embodiments, the interference temperature can be expressed as the signal-to-interference plus-noise ratio (SINR).

[0084] In some embodiments, the broadcast message may further include interference cancellation instruction information, which is used to instruct the secondary user on how to perform interference cancellation.

[0085] In some embodiments, the interference cancellation indication information includes one of the following interference cancellation methods: serial interference cancellation and parallel interference cancellation.

[0086] In this embodiment of the disclosure, interference cancellation indication information can be added to the broadcast information of the communication system to which the primary user belongs. This indication information may be an instruction for the secondary user to use serial interference cancellation or parallel interference cancellation.

[0087] It should be noted that serial interference cancellation and parallel interference cancellation can be used in non-orthogonal access scenarios as well as in spectrum sharing scenarios.

[0088] In one example, when using non-orthogonal multiple access, successive interference cancellation is enabled. The main system's signal is demodulated from the received signal and then cancelled. Finally, its own signal is demodulated.

[0089] In some embodiments, secondary users can choose an interference cancellation method based on their hardware capabilities and service latency requirements. The terminal side can also choose a suitable interference cancellation method based on its hardware capabilities and service latency requirements. Serial interference cancellation has low hardware requirements but a long processing time, while parallel interference cancellation has high hardware requirements but a short processing time.

[0090] In some embodiments, when the communication system needs to transmit data, the communication system broadcasts a message indicating that secondary users are not allowed to access the system while it is communicating. If the primary user's communication system needs to transmit data, the communication system must first indicate in the primary system broadcast message that secondary users are not allowed to access the system while it is communicating. After a period of time, the secondary user can then resume normal communication. During communication, the primary system message can be configured as needed (e.g., a 3ms wait for the secondary user to receive and demodulate the signal, allowing the primary user's communication system to broadcast the message and exit spectrum usage).

[0091] Spectrum sharing and NOMA are two technical solutions that effectively improve spectrum utilization and are expected to be adopted in future 6G networks. The solution provided in this disclosure combines the advantages of NOMA and spectrum sharing, improving the overall spectrum utilization of the network and reducing energy consumption.

[0092] Figure 4 This diagram illustrates a communication method according to an embodiment of the present disclosure. This embodiment is applied to a communication system containing primary and secondary users. The time-frequency resources of the primary user and the secondary user are the same, but the primary and secondary users belong to different communication systems. The structure is as shown above. Figure 2 As shown.

[0093] like Figure 4 As shown, the communication method provided in this embodiment includes steps S402-S406.

The secondary user can determine the access method to access the communication system from multiple preset access methods according to the access indication information. Since the access indication information is determined based on the communication status information of the communication system where the primary user is located, the access indication information can better guarantee the communication quality of the primary user, and at the same time guide the secondary user to select a more suitable access method, which can improve the spectrum utilization of the overall network and reduce energy consumption.
