[0025] This disclosure provides a communication method, communication device, communication system, storage medium, and program product.

[0026] In a first aspect, embodiments of this disclosure propose a communication method executed by a terminal, the method comprising: determining whether communication transmission of a first network type can be performed based on a first resource, wherein the first resource is a communication resource shared by multiple network types.

[0027] In the above embodiments, the terminal determines whether communication transmission of a first network type is possible based on a first resource, wherein the first resource is a communication resource shared by multiple network types. This is a novel resource-sharing mechanism. Resource sharing means allowing the available resources of multiple network types to overlap, thereby achieving seamless resource coverage across multiple network types. This not only supports seamless switching between multiple network types but also avoids resource waste. Moreover, the available resources for each network type can be significantly increased. By sharing the first resource among multiple network types, resource utilization can be improved. By determining whether communication transmission of the first network type is possible based on the first resource, the terminal can avoid resource conflicts and interference caused by multiple networks simultaneously using shared resources, thus ensuring communication quality.

[0028] In conjunction with some embodiments of the first aspect, in some embodiments, the first network type includes at least one of the following:

[0029] Terrestrial network types;

[0030] Non-terrestrial network type.

[0031] In the above embodiments, by determining whether communication transmission of terrestrial network type and / or non-terrestrial network type can be performed based on the first resource, the terminal can avoid resource conflicts and interference caused by multiple networks using shared resources at the same time, thus ensuring the communication quality of terrestrial network and / or non-terrestrial network.

[0032] In conjunction with some embodiments of the first aspect, in some embodiments, the first resource includes frequency domain resources, and determining whether communication transmission of the first network type can be performed based on the first resource includes: determining that communication transmission of the first network type can be performed based on the first resource if at least one of the following conditions is met:

[0128] In some embodiments, the frequencies allocated to cellular and satellite communications are not the same. Satellite spectrum sharing mechanisms achieve interference isolation between satellite and ground by establishing protected areas between the satellite service area and the terrestrial network service area. Within these protected areas, no terrestrial base stations exist, and the satellite beam does not provide signal coverage. While this enables spectrum sharing between satellite and ground, coverage gaps exist within the protected areas, preventing users from seamlessly switching between terrestrial base stations and satellite communication.

[0129] In some embodiments, frequency sharing mechanisms become crucial given the extremely limited availability of frequency resources. With the rapid development of cellular communication, the spectral efficiency of terrestrial networks has significantly improved, far exceeding that of satellite communication, making human communication increasingly reliant on frequency resources allocated to cellular networks. This has prompted cellular network operators to acquire frequency resources from satellite operators to provide users with a better cellular network experience. On the other hand, when satellites operate in the frequency bands designated for mobile satellite services, the limited bandwidth makes it difficult to support the access needs of a large number of users over a wide area. Therefore, satellites using terrestrial mobile network spectrum has become a highly attractive option.

[0130] In some embodiments, to achieve seamless global coverage, the service areas of terrestrial base stations and satellite beam service areas need to overlap. However, when satellite and terrestrial coverage overlap and share the same frequency band spectrum resources, the interference problem between cellular and satellite communications must be addressed to ensure the quality of communication services.

[0131] In view of this, embodiments of this disclosure propose a communication method, communication device, communication system, storage medium, and program product. This communication method achieves resource sharing among multiple network types through a dynamic resource sharing mechanism. For example, it achieves satellite-to-ground spectrum sharing through spectrum coordination between terrestrial base stations and satellite networks.

[0132] Figure 2A is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2A, the embodiment of the present disclosure relates to a communication method executed by a communication system 100, and the method includes at least one of the following steps:

[0133] In step S2101, terminal 101 determines the first time period and the first frequency band.

[0134] In some embodiments, the first time period and the first frequency band are used for wireless measurement.

[0135] It should be noted here that multiple network types can share communication resources. For example, multiple network types can share a first resource. This first resource can be defined by a protocol. The first resource includes, but is not limited to, frequency domain resources and time domain resources. The first frequency band refers to some or all of the frequency domain resources shared among multiple network types. The first time period refers to some or all of the time domain resources shared among multiple network types.

[0136] Optionally, the first frequency band and / or the first time period are specified by the protocol, or the first frequency band and / or the first time period are indicated to the terminal by the network device, or the first frequency band and / or the first time period are selected by the terminal.

[0137] For example, the terminal determines the first frequency band for wireless measurement according to the protocol.

[0138] For example, the terminal receives indication information sent by the network device, and the terminal determines a first frequency band for performing wireless measurements based on the received indication information. The network device may send the indication information based on a request from the terminal, or the network device may actively send the indication information to the terminal.

[0139] For example, the terminal selects the first frequency band based on its own hardware capabilities, service requirements, and network environment. Hardware capabilities include, for example, the frequency range supported by the RF front-end and the capabilities of the modem. Service requirements include, for example, the amount of data transmission and the required efficiency of data transmission.

[0140] For example, the terminal determines the first time period for wireless measurement according to the protocol.

[0141] For example, the terminal determines the first time period based on the instructions of the network device.

[0142] For example, the terminal determines the first time period based on information such as business needs and network environment.

[0143] In some embodiments, step S2101 may be omitted.

[0144] In step S2102, terminal 101 performs wireless measurement based on the first time period and the first frequency band to obtain the measurement result of the first frequency band.

[0145] In some embodiments, the terminal performs wireless measurements on a first frequency band within a first time period to obtain measurement results for the first frequency band. The measurement results for the first frequency band may include at least one of the following:

[0146] Received Signal Strength Indication (RSSI);

[0147] Reference Signal Received Power (RSRP);

[0148] Reference Signal Received Quality (RSRQ).

[0149] Of course, the measurement results for the first frequency band may also include information such as the signal-to-interference-plus-noise ratio (SINR), whether the frequency band is occupied, and signal propagation delay. This disclosure does not limit this information.

[0150] For example, the measurement results for the first frequency band include RSSI.

[0151] For example, the measurement results for the first frequency band include RSRP.

[0152] For example, the measurement results for the first frequency band include RSRQ.

[0153] In some embodiments, step S2102 may be omitted.

[0154] In step S2103, terminal 101 performs cell measurements on the serving cell and neighboring cells to obtain the measurement results of the serving cell and neighboring cells.

[0155] Optionally, the serving cell of the terminal is a cell of the first network type.

[0156] Of course, the current serving cell of the terminal may not be a cell of the first network type.

[0157] Optionally, the neighboring cell is a neighboring cell with a network type different from the serving cell on the first resource or the first frequency band. For example, if the serving cell has a first network type, then the neighboring cell is a cell with a second network type on the first resource or the first frequency band. Optionally, the neighboring cell can be configured to the terminal by the network device. The number of neighboring cells can be one or more.

[0158] In some embodiments, the first network type includes at least one of the following:

[0159] Terrestrial network types;

[0160] Non-terrestrial network type.

[0161] It should be explained that terrestrial network types refer to communication networks deployed and operated on or near the Earth's surface. Non-terrestrial network types refer to networks that do not rely on ground infrastructure but communicate through airborne or space platforms such as satellites. Terrestrial and non-terrestrial networks can be combined, for example, in the form of integrated space-ground networks.

[0162] For example, if the serving cell of the terminal is a terrestrial network type cell, then the neighboring cell can be a non-terrestrial network type neighboring cell on the first resource or the first frequency band.

[0163] For example, if the serving cell of the terminal is a non-terrestrial network type cell, then the neighboring cell can be a terrestrial network type neighboring cell on the first resource or the first frequency band.

[0164] Optionally, the measurement results of the serving cell include at least one of RSSI, RSRP, and RSRQ.

[0165] Optionally, the measurement results of neighboring cells include at least one of RSSI, RSRP, and RSRQ.

[0166] Of course, the measurement results of the serving cell and neighboring cells may also include information such as SINR, cell load, and signal propagation delay. This disclosure does not limit this information.

[0167] For example, the measurement results of the serving cell include RSRP and RSRQ.

[0168] For example, the measurement results of neighboring cells include RSRP and RSRQ.

[0169] In some embodiments, step S2103 may be omitted.

[0170] In step S2104, terminal 101 determines the propagation time error between the serving cell and neighboring cells.

[0171] In some embodiments, the terminal can calculate the propagation time error based on the distance between the terminal and the base station corresponding to the serving cell, and the distance between the terminal and the base station corresponding to a neighboring cell. The distance between the terminal and the base station can be calculated based on the terminal's location information and the base station's location information. The base station's location information can be obtained from the base station.

[0172] In some embodiments, the serving cell and neighboring cells can transmit reference signals simultaneously, and the terminal can measure the timestamps of the reference signals received from the serving cell and neighboring cells respectively. By calculating the difference between these two timestamps, the propagation time error can be obtained.

[0173] In some embodiments, if both the terminal and the base station use GPS time synchronization, the terminal can record the GPS timestamps of the received signals from the serving cell and neighboring cells. By comparing these timestamps, the propagation time error can be calculated.

[0174] In some embodiments, the terminal can send a signal to the base station and measure the round-trip time of the signal. In this way, the terminal can calculate the round-trip time difference with the serving cell and neighboring cells. The one-way propagation time error can be determined based on the round-trip time difference.

[0175] In some embodiments, step S2104 may be omitted.

[0176] In step S2105, terminal 101 determines whether communication transmission of the first network type can be performed based on the first resource.

[0177] According to the embodiment of step S2101, multiple network types can share the first resource. The multiple network types include the first network type.

[0178] In some embodiments, the implementation of a terminal determining whether communication transmission of a first network type is possible based on a first resource may include: determining that communication transmission of a first network type is possible based on a first resource if at least one of the following conditions is met:

[0179] The measurement result of the first frequency band or the first resource is less than the first threshold, and the first frequency band is at least a part of the first resource;

[0180] If the measurement result of the serving cell is greater than the second threshold, the serving cell is a cell of the first network type;

[0181] If the measurement result of a neighboring cell is less than the third threshold, the neighboring cell is a cell with a different network type from the serving cell on the first frequency band or the first resource.

[0182] The propagation time error between the serving cell and neighboring cells is greater than the fourth threshold.

[0183] The first, second, third, and fourth thresholds can be specified by the protocol or indicated by the network device. Optionally, the second threshold is greater than the third threshold.

[0184] For example, suppose the measurement results for the first frequency band indicate that the load on the first frequency band is relatively low. For instance, if the measurement results for the first frequency band include RSSI, and the RSSI of the first frequency band is less than a first threshold, it indicates that the load on the first frequency band is relatively low. In the case of low load on the first frequency band, it can be determined that communication transmission between the terminal and the network device can be performed using a first network type based on a first resource. Here, the first network type can be the network type corresponding to the terminal's current serving cell, or it can be a different network type than the terminal's current serving cell. Preferably, the first network type is the network type corresponding to the terminal's current serving cell.

[0185] For example, assuming the measurement results of the serving cell and neighboring cells include RSRP / RSRQ, if the RSRP / RSRQ of the serving cell is greater than a second threshold and the RSRP / RSRQ of the neighboring cells is less than a third threshold, then it can be determined that the terminal and the network device can perform communication transmission of a first network type according to the first resource. Here, the first network type is the network type corresponding to the terminal's current serving cell.

[0186] For example, if the propagation time error between the serving cell and neighboring cells is greater than a fourth threshold, it can be determined that the terminal and the network device can perform communication transmission of a first network type based on the first resource. Here, the first network type is the network type corresponding to the terminal's current serving cell.

[0187] It should be noted that the above examples are not exhaustive, and the examples can be combined with each other, which is not limited in this disclosure. For example, if the RSRP / RSRQ of the serving cell is greater than the second threshold, the RSRP / RSRQ of the neighboring cell is less than the third threshold, and the propagation time error between the serving cell and the neighboring cell is greater than the fourth threshold, then it can be determined that the terminal and the network device can perform communication transmission of the first network type according to the first resource.

[0188] In step S2106, if it is determined that communication transmission of the first network type can be performed based on the first resource, the terminal 101 and the network device 102 perform communication transmission of the first network type based on the first resource during the second time period.

[0189] In some embodiments, if it is determined that communication transmission of the first network type can be performed between the network device and the terminal based on the first resource, communication transmission of the first network type is performed with the network device based on the first resource during a second time period.

[0190] Optionally, the implementation of communication transmission of the first network type with the network device based on the first resource during the second time period includes: communication transmission of the first network type with the network device based on the first frequency band during the second time period.

[0191] Among them, communication and transmission between terminals and network devices refers to the ability for terminals and network devices to communicate with each other and send user data, control signals, etc.

[0192] Optionally, the second time period is represented by a start time and a duration.

[0193] Optionally, the second time period is specified by the protocol; or, the second time period is indicated by the network device; or, the second time period is determined based on the propagation time error; or, the second time period is requested by the terminal from the network device based on its data transmission and reception needs.

[0194] For example, the second time period is determined by the terminal based on the propagation time error, and the duration of the second time period is less than or equal to the propagation time error.

[0195] For example, the second time period is when the terminal requests data from the network device based on its data transmission and reception needs.

[0196] In some embodiments, if the terminal's current serving cell is a cell of a first network type, the second time period is a future time period. For example, the start time of the second time period could be the time when communication transmission of the first network type can be determined based on the first resource.

[0197] In some embodiments, if the terminal's current serving cell is not a cell of the first network type, then the second time period can be the time period after the terminal switches to a network of the first network type. For example, the start time of the second time period can be the moment when the terminal successfully switches to a network of the first network type.

[0198] In some embodiments, the network device may perform the same process as the terminal in determining whether communication transmission of the first network type is possible based on the first resource. If both the network device and the terminal determine that communication transmission of the first network type is possible based on the first resource, the terminal and the network device perform communication transmission of the first network type based on the first resource during a second time period, thereby maintaining consistency between the terminal and the network device. The network device may obtain relevant data from the terminal for determining whether communication transmission of the first network type is possible based on the first resource. For example, the network device receives first information sent by the terminal and determines whether communication transmission of the first network type is possible based on the first information; wherein the first information includes at least one of the following:

[0199] Measurement results for the first frequency band;

[0200] Measurement results of the service area;

[0201] Measurement results from neighboring communities;

[0202] The propagation time error between the serving cell and neighboring cells;

[0203] Relevant information used to calculate propagation time error.

[0204] It should be noted that the process by which the network device determines whether the terminal and the network device can perform communication transmission of the first network type based on the first resource is the same as the process by which the terminal determines whether it can perform communication transmission of the first network type based on the first resource, and will not be described again here.

[0221] Figure 2B is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2B, the embodiment of the present disclosure relates to a communication method executed by a communication system 100, and the method includes at least one of the following steps:

[0222] In step S2201, terminal 101 sends first information to network device 102.

[0223] In some embodiments, the network device receives first information. For example, network device 102 receives first information sent by terminal 101.

[0224] In some embodiments, the first information is used to request the network device to determine whether communication transmission of the first network type can be performed based on the first resource.

[0225] In some embodiments, the name of the first information is not limited, and it may be, for example, a judgment request, an instruction message, an operation command, etc.

[0226] In some embodiments, the first information may include at least one of the following:

[0227] Measurement results for the first frequency band;

[0228] Measurement results of the service area;

[0229] Measurement results from neighboring communities;

[0230] The propagation time error between the serving cell and neighboring cells;

[0231] Relevant information used to calculate propagation time error.

[0232] It should be noted that the measurement results of the first frequency band, the measurement results of the serving cell, the measurement results of the neighboring cells, the propagation time error between the serving cell and the neighboring cells, and the methods for obtaining relevant information used to calculate the propagation time error can be found in the corresponding embodiment in Figure 2B, and will not be described here again.

[0233] In step S2202, network device 102 determines whether it can perform communication transmission of the first network type based on the first information.

[0234] In some embodiments, the implementation of a network device determining whether communication transmission of a first network type is possible based on a first resource may include: determining that communication transmission of the first network type is possible based on the first resource if at least one of the following conditions is met:

[0235] The measurement result of the first frequency band or the first resource is less than the first threshold, wherein the first frequency band is at least a part of the first resource;

[0236] If the measurement result of the serving cell is greater than the second threshold, the serving cell is a cell of the first network type;

[0237] If the measurement result of a neighboring cell is less than the third threshold, the neighboring cell is a cell with a different network type from the serving cell on the first frequency band or the first resource.

[0238] The propagation time error between the serving cell and neighboring cells is greater than the fourth threshold.

[0239] The first, second, third, and fourth thresholds can be specified by the protocol or indicated by the network device. Optionally, the second threshold is greater than the third threshold.

[0240] For example, suppose the measurement results for the first frequency band indicate that the load on the first frequency band is relatively low. For instance, if the measurement results for the first frequency band include RSSI, and the RSSI of the first frequency band is less than a first threshold, it indicates that the load on the first frequency band is relatively low. In the case of low load on the first frequency band, it can be determined that communication transmission between the terminal and the network device can be performed using a first network type based on a first resource. Here, the first network type can be the network type corresponding to the terminal's current serving cell, or it can be a different network type than the terminal's current serving cell. Preferably, the first network type is the network type corresponding to the terminal's current serving cell.

[0241] For example, assuming the measurement results of the serving cell and neighboring cells include RSRP / RSRQ, if the RSRP / RSRQ of the serving cell is greater than a second threshold and the RSRP / RSRQ of the neighboring cells is less than a third threshold, then it can be determined that the terminal and the network device can perform communication transmission of a first network type according to the first resource. Here, the first network type is the network type corresponding to the terminal's current serving cell.

[0242] For example, if the propagation time error between the serving cell and neighboring cells is greater than a fourth threshold, it can be determined that the terminal and the network device can perform communication transmission of a first network type based on the first resource. Here, the first network type is the network type corresponding to the terminal's current serving cell.

[0243] It should be noted that the above examples are not exhaustive, and the examples can be combined with each other, which is not limited in this disclosure. For example, if the RSRP / RSRQ of the serving cell is greater than the second threshold, the RSRP / RSRQ of the neighboring cell is less than the third threshold, and the propagation time error between the serving cell and the neighboring cell is greater than the fourth threshold, then it can be determined that the terminal and the network device can perform communication transmission of the first network type according to the first resource.

[0244] In step S2203, network device 102 sends the judgment result to terminal 101.

[0245] In some embodiments, the terminal receives a judgment result. For example, terminal 101 receives a judgment result sent by network device 102. This judgment result is the network device's feedback on the first information.

[0246] In some embodiments, the determination result may be that the terminal and the network device can perform communication transmission of a first network type based on the first resource.

[0247] In some embodiments, the determination result may be that the terminal and the network device cannot perform communication transmission of the first network type based on the first resource.

[0248] In step S2204, if the judgment result indicates that communication transmission of the first network type can be performed according to the first resource, the terminal 101 and the network device 102 shall perform communication transmission of the first network type according to the first resource in the second time period.

[0249] In some embodiments, after the terminal receives the determination result, both the network device and the terminal determine that they can perform communication transmission of the first network type according to the first resource. In this case, the terminal and the network device can perform communication transmission of the first network type according to the first resource in a second time period, thereby maintaining the consistency between the terminal and the network device.

[0250] Optionally, the implementation of communication transmission of the terminal and network device according to the first resource and the first network type in the second time period includes: the terminal and network device transmitting communication of the first network type according to the first frequency band in the second time period.

[0251] Optionally, the second time period is specified by the protocol; or, the second time period is determined by the network device; or, the second time period is determined based on the propagation time error; or, the second time period is requested by the terminal from the network device based on its data transmission and reception needs.

[0252] For example, the duration of the second time period is less than or equal to the propagation time error.

[0253] In some embodiments, the second time period is a future time period. For example, the start time of the second time period may be the time when communication transmission of the first network type can be determined based on the first resource.

[0254] In some embodiments, the second time period can be the time period after the terminal switches to a network of the first network type. For example, the start time of the second time period can be the moment when the terminal successfully switches to a network of the first network type.

[0350] In this embodiment of the disclosure, since cellular networks and non-terrestrial networks are currently still isolated from each other, this embodiment of the disclosure can achieve dynamic spectrum sharing between TN and NTN through a spectrum sharing mechanism, that is, TN networks and NTN networks share the same spectrum resources. During application, it can be determined whether the shared frequency band can be used to perform communication transmission for a specific network type based on conditional judgments.

[0351] In some embodiments, it is determined based on certain conditions whether a specific network type of communication transmission can be performed using a specific frequency band (i.e., a shared frequency band).

[0352] Optionally, a specific frequency band refers to a frequency band that can be shared by TN and NTN. Optionally, the specific frequency band is defined by the protocol.

[0353] Optionally, communications for specific network types include: TN and / or NTN.

[0354] Optionally, the judgment condition includes at least one of the following:

[0355] 1. The RSSI measurement result for a specific frequency band is less than the threshold 1;

[0356] 2. The measurement result of the serving cell for a specific network type is greater than threshold 2, and the RSRP / RSRQ measurement result of the neighboring cell is less than threshold 3;

[0357] 3. The propagation delay error between the serving cell and neighboring cells of a specific network type is greater than the threshold 4;

[0358] Optionally, the determination process can be performed by the UE or by the network.

[0359] In some embodiments, specifically for judgment condition 1, the UE determines the time and frequency resources used to measure RSSI and performs the measurement.

[0360] Optionally, the frequency resources are at least a portion of a specific frequency band.

[0361] Optionally, the determination method includes at least one of the following:

[0362] The specification pre-configures time and frequency resources by default;

[0363] The network configures and distributes time and frequency resources for measuring RSSI.

[0364] The UE decides autonomously which time and frequency resources to use for RSSI measurement.

[0365] Optionally, the RSSI measurement result is compared with the corresponding threshold (by protocol or network implementation). If the measurement result is less than the threshold, the load on that frequency band is low, and a shared frequency band can be used to perform communication transmission for a specific network type.

[0366] In some embodiments, specifically for judgment condition 2, the UE performs RSRP / RSRQ measurements of the current serving cell and RSRP / RSRQ measurements of neighboring cells with different network types on the shared frequency band based on the network configuration, and obtains the measurement results; the measurement results are compared with the corresponding thresholds (protocol agreement or network implementation). If the measurement results of all neighboring cells on a certain frequency point are less than threshold 3, and the serving cell is greater than threshold 2, then the frequency point is considered to be usable for performing communication transmission with the same network type as the serving cell.

[0367] In some embodiments, specifically regarding judgment condition 3, the UE, based on network configuration, calculates the propagation time error between the serving cell and neighboring cells of a different network type. The UE compares the obtained propagation time error with a corresponding threshold (protocol-defined or network-implemented). If the error exceeds the threshold, the UE reports that the network can perform network type communication transmissions of the same network type as the serving cell within the propagation time error range. For example, the UE performs network type communication transmissions of the same network type as the serving cell in a future second time period, where the length of the second time period is equal to the propagation time error.

[0368] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device.

For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD).

In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
