[0113] The continuous emergence of new Internet applications such as new generation of augmented reality (AR) / virtual reality (VR) and vehicle-to-vehicle communication puts higher requirements on wireless communication technology, which drives the continuous evolution of wireless communication technology to meet the needs of applications. At present, cellular mobile communication technology is in the evolution stage of new generation technology. One important feature of the new generation technology is to support flexible configuration of multiple service types. Different service types have different requirements for wireless communication technology. For example, the main requirements of enhanced mobile broadband (eMBB) service type focus on large bandwidth and high rate; the main requirements of ultra reliable low latency communication (URLLC) service type focus on high reliability and low latency; the main requirements of massive machine type communication (mMTC) service type focus on large number of connections. Therefore, the new generation of wireless communication system needs flexible and configurable design to support the transmission of multiple service types.

[0114] In the research of wireless communication technology, satellite communication is considered as an important aspect of the development of future wireless communication technology. Satellite communication refers to the communication between radio communication devices on the ground using satellites as relays. The satellite communication system is composed of satellite part and ground part. The characteristics of satellite communication are: large communication range; communication can be carried out between any two points as long as they are within the coverage of satellite transmission; not easily affected by land disasters (high reliability). As a supplement to the current ground cellular communication system, satellite communication has the following advantages:

[0115] 1. Extended coverage: For areas that cannot be covered by the current cellular communication system or have high coverage costs, such as oceans, deserts, remote mountainous areas, etc., satellite communication can solve the communication problem.

[0116] 2. Emergency communication: In the case of extreme conditions such as earthquakes that cause the infrastructure of cellular communication to be unavailable, satellite communication can quickly establish communication connection.

[0117] 3. Provide industry applications: For example, for long-distance transmission of delay-sensitive services, satellite communication can be used to reduce the delay of service transmission.

[0118] It can be predicted that in the future wireless communication system, satellite communication system and terrestrial cellular communication system will gradually realize deep integration, and truly realize the intelligent connection of everything.

[0119] In a satellite communication system, due to a large propagation distance, there is a large deviation in the uplink and downlink transmission timing. The terminal needs to maintain the uplink synchronization based on the global navigation satellite (GNSS) measurement and some auxiliary information.

[0120] For the scenario of satellite communication, due to the long signal transmission distance between the sending end and the receiving end, there is a large time for data transmission. For the transmission with uplink and downlink relationship, the introduction of a delay parameter is determined in the current standardization discussion to compensate for the transmission delay. In order to determine the delay parameter, the terminal needs to report the position information.

[0121] Since the communication resources dedicated for satellite communication are very limited, in order to realize the support of satellite communication for large data volume services, the spectrum sharing mechanism between NTN and TN is a research direction. Among them, the sharing method of spectrum can include: fixed division; semi-static division; dynamic sharing, etc.

[0122] To solve the above problems, the present disclosure provides a communication method, which is a method for sharing communication spectrum between a satellite communication system and a terrestrial communication system, which can effectively enable the satellite communication system to have more spectrum resources for communication and improve the communication capability of the satellite communication system. The specific content of the method is as follows.

[0123] FIG. 2 is an interaction diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG. 2, the present embodiment relates to a communication method for a communication system 100, which can include a terminal 101 and a network device 102. The above method includes the following steps.

[0124] In step 2101, the network device sends configuration information to the terminal.

[0125] In some embodiments, the configuration information includes configuration information of time domain, frequency domain, space domain, and power for the terminal to send second information. The second information can be used to indicate the resource requirement of the terminal, in other words, the terminal can determine the time domain, frequency domain, space domain, and power information of the resource requirement report according to the configuration information, and report the resource requirement according to the related information.

[0126] In some embodiments, the configuration information includes at least one of time domain configuration information for determining spectrum detection and indication information of a target detection method.

For example, the indication information of the target detection method can indicate that the target detection method is based on energy detection or signal feature detection to detect the frequency usage rate on the target resource.

[0129] For example, the indication information of the target detection method can indicate the target detection method adopted by the information segment, such as a bit map. The specific indication manner can be determined according to actual conditions, which is not limited in the present disclosure.

For example, the terminal can report the carrier information of the required resource carrier, such as the frequency point bandwidth and the like.

[0137] Optionally, the terminal can report the usage information of the required resource through the second information, that is, the terminal can report the usage information of the candidate resource, and the terminal can report the usage state of the resource expected to be used by the terminal to the network device through the report of the usage information of the candidate resource. For example, the terminal can store a set of usage information of part of the resources, and the terminal can determine a candidate resource expected to be used from the set and report it to the network device. For example, the terminal can determine the resource with the lowest spectrum utilization rate in the set as the resource expected to be used, and report it to the network device.

[0138] In step 2103, the terminal sends the second information to the network device.

[0139] In some embodiments, the terminal sending the second information to the network device includes:

[0140] Based on the predefinition or the configuration information of the network device, the configuration information of the resource for sending the second information is determined, and the configuration information of the time domain, frequency domain, space domain and power for sending the second information is determined based on the resource configuration information. The second information is sent to the network device based on the resource configuration information.

[0141] Optionally, the terminal can determine the configuration information of the time domain, frequency domain, space domain and power for sending the second information according to the protocol definition, and send the second information according to the configuration information.

[0142] Optionally, the terminal can receive the configuration information sent by the network device, and determine the configuration information of the time domain, frequency domain, space domain and power for sending the second information according to the received configuration information, and send the second information according to the configuration information.

[0143] In step 2104, the terminal determines the first information.

[0144] In some embodiments, the first information is used to indicate the candidate available spectrum resource for communication between the terminal and the network device.

[0145] In other words, the terminal can determine the candidate available spectrum resource for communication between the terminal and the network device.

[0158] At step 2105, the network device sends trigger information to the terminal.

[0159] In some embodiments, the network device can send trigger information to the terminal, and the trigger information can be used to trigger the terminal to report the first information, i.e., the terminal can report the available spectrum resources based on the trigger of the network device.

[0160] In some embodiments, the step is optional, and when the terminal reports the first information in other cases, e.g., the terminal sends the first information when the first information meets the preset condition, the step can be omitted.

[0166] Optionally, the terminal can send the first information according to the predefined rule, i.e., the terminal can send the first information to the network device when the first information meets the preset condition. For example, the preset condition can be that the frequency usage rate is detected to be less than a predefined threshold value, wherein the threshold value can be set according to the actual use scenario, which is not limited by the present disclosure.

[0167] Optionally, the network device can send information to the terminal to trigger the terminal to report the first information.

[0168] Optionally, the terminal can receive the configuration information sent by the network device, and determine the resource location for reporting the first information according to the configuration information. The terminal can send the first information at the determined resource location.

[0229] The following is an exemplary introduction to the above method.

[0230] The method shown in the embodiments of the present disclosure relates to a method for satellite communication spectrum sharing, and the complete content of the method is as follows.

[0231] 1. The terminal reports resource demand related information.

[0232] The terminal determines the configuration information for reporting resource demand based on a pre-defined manner or a manner of receiving configuration information from the base station. The configuration information can include configuration information for reporting time domain, frequency domain, space domain, and power, etc.

[0233] The terminal can report the demand for communication resources based on the demand of the service. The communication resources can be carrier granularity communication resources, PRB granularity communication resources, PRB set granularity communication resources, or other granularity communication resources, etc.

[0234] The reported resource information can also include indication information of the target communication resources, such as carrier information of the target carrier, etc.

[0235] The reported resource information can also include the spectrum utilization rate of the target resource. The terminal can report a suitable value based on the obtained spectrum utilization rate of the target resource in the target spectrum utilization rate set.

[0236] 2. The terminal determines the resource information for communication.

[0237] The terminal determines the communication resources based on a pre-defined manner or a manner notified by the base station. The communication resources can be carrier granularity communication resources, PRB granularity communication resources, PRB set granularity communication resources, or other granularity communication resources, etc.

[0238] In one implementation, the terminal determines the resource information for communication based on a predefined manner. The terminal continuously or periodically senses the usage of TN spectrum and reports the available spectrum resource information to the base station according to the predefined rule

[0239] The terminal can continuously detect the frequency usage on the target resource. The determination of the frequency usage can be based on a target detection method. For example, the target detection method can be based on energy detection. The terminal determines the frequency resource utilization on the communication resource based on the energy of the detected transmission signal on the target resource.

[0240] Alternatively, the terminal can sense the usage of the target spectrum according to a target detection manner. The determination of the frequency usage can be based on a target detection method. For example, the target detection method can be based on energy detection. The terminal determines the frequency resource utilization on the communication resource based on the energy of the detected transmission signal on the target resource. The target detection manner can be determined based on the configuration information received from the base station. The configuration information can include time domain configuration information for determining the detection time, such as period, duration, start position, end position, etc. The configuration information can also include indication information of the target detection manner. For example, it can indicate whether to perform energy detection or signal feature detection to detect the frequency usage on the target resource.

[0241] The terminal reports the detection result according to the predefined rule or the rule configured by the base station. The detection result can include indication information of the target available resource, resource utilization on the target resource, etc. The terminal reports the detection result based on the predefined manner. The predefined rule can be that when the frequency usage is detected to be less than a predefined threshold. Alternatively, the terminal receives the configuration information from the base station to determine the resource position for reporting.

[0242] The terminal autonomously determines the resource information for communication.

[0243] In one implementation, the terminal receives the configuration from the base station to determine the resource information for communication. Similarly, the terminal continuously or periodically senses the usage of TN spectrum and reports the available spectrum resource information to the base station according to the predefined rule

[0244] The terminal can continuously detect the frequency usage on the target resource. The determination of the frequency usage can be based on a target detection method. For example, the target detection method can be based on energy detection. The terminal determines the frequency resource utilization on the communication resource based on the energy of the detected transmission signal on the target resource.

[0245] Alternatively, the terminal can perceive the usage of the target spectrum in a target detection manner. The determination of the frequency usage can be based on the target detection method, such as the target detection method can be based on energy detection, and the terminal determines the frequency resource utilization on the communication resource based on the energy of the detected transmission signal on the target resource. The target detection manner can be determined based on the configuration information of the base station. The configuration information can include time domain configuration information for determining the detection time, such as period, duration, start position, end position, and the like. The configuration information can also include indication information of the target detection manner. For example, it can be indicated that the detection of the frequency usage on the target resource is based on energy detection or signal feature detection.

[0246] The terminal reports the detection result according to the predefined rule or the rule configured by the base station. The detection result can include indication information of the target available resource, resource utilization on the target resource, and the like. The terminal reports the detection result based on the predefined manner. The predefined rule can be that when the frequency usage is detected to be less than a predefined threshold. Alternatively, the terminal receives the configuration information of the base station to determine the resource position for reporting.

[0247] In summary, the above embodiments of the present scheme provide a method for sharing communication spectrum between a satellite communication system and a terrestrial communication system, which can effectively enable the satellite communication system to have more spectrum resources for communication, and improve the communication capability of the satellite communication system.
