[0134] In the research of wireless communication technology, satellite communication is an important aspect of the future development of wireless communication technology. Satellite communication can be understood as the communication of ground radio communication equipment using satellites as relays. A satellite communication system can be composed of a satellite part and a ground part. Satellite communication has a large communication range. Within the range covered by the satellite's radio waves, communication can be established between any two points. Satellite communication is highly reliable and is not easily affected by land disasters.

[0135] As a supplement to the ground cellular communication system, satellite communication has the following advantages:

[0136] 1. Extended coverage: For areas that cannot be covered by the current cellular communication system or have high coverage costs, such as oceans, deserts, and remote mountainous areas, satellite communication can solve the communication problem.

[0137] 2. Emergency communication: In the event of a disaster, such as an earthquake, which causes the infrastructure of the cellular communication system to be unavailable, satellite communication can quickly establish a communication connection.

[0138] 3. Provide industry applications: For example, for long-distance transmission of time-sensitive services, satellite communication can reduce the transmission delay of services.

[0139] In the future wireless communication system, satellite communication systems and ground cellular communication systems will gradually achieve deep integration to realize the intelligent connection of all things.

[0140] In a satellite communication system, due to the propagation distance between the satellite and the terminal, there will be a large deviation in the uplink and downlink timing. The terminal needs to measure based on the global navigation satellite system (GNSS) and auxiliary information to maintain the synchronization of the uplink.

[0141] In the space-air-ground integrated deployment, there may be a scenario where satellites in different orbits overlap to cover the same area. FIG. 1B is a satellite communication system architecture diagram of space-air-ground integrated deployment according to an embodiment of the present disclosure, as shown in FIG. 1B, the satellite communication system includes a satellite in geosynchronous orbit (GEO) 111, a medium earth orbit (MEO) / low earth orbit (LEO) 112 satellite, a high altitude platform system (HAPS) 113, and a terrestrial network (TN) 114.

[0142] In some embodiments, the beams transmitted by the satellites operating in GEO and the beams transmitted by the satellites operating in MEO / LEO can cover the same area.

[0143] In some embodiments, the HAPS 113 can include a drone, a helicopter, an airplane, a dirigible, and the like, without limitation of the embodiments of the present disclosure.

[0144] To support the continuity of data services and large data volume services, multi-satellite data transmission is a possible technical direction. FIG. 1C is a schematic diagram of multi-satellite providing services according to an embodiment of the present disclosure. As shown in FIG. 1C, satellite 1 and satellite 2 can both provide services for terminal 1. Satellite 1 is the primary service satellite, providing a primary service beam, and satellite 2 is the secondary service satellite, providing a secondary service beam. However, it is necessary to determine how the terminal transmits data with multiple satellites.

[0145] In some embodiments, in the future space-air-ground integrated deployment, there can be a scenario in which multiple satellites operating in different orbits overlap to cover the same area. In this case, the current communication mode in which the terminal connects to a single satellite can not meet the needs of satellite communication.

[0146] FIG. 2A is one of the exemplary interaction diagrams of the communication method according to an embodiment of the present disclosure. As shown in FIG. 2A, the embodiments of the present disclosure relate to a communication method. The communication method is performed by the communication system 100 and includes steps S2101 to S2108.

[0147] In step S2101, the terminal transmits third information.

[0148] In some embodiments, the network device receives the third information.

[0149] In some embodiments, the third information is used to indicate the support capability of the terminal for multi-satellite data transmission.

[0150] In some embodiments, the name of the third information is not limited, for example, it is “capability indication information”, “capability configuration information”, and the like.

[0151] In some embodiments, the third information includes at least one of the following: the maximum number of satellites that the terminal supports to connect simultaneously (denoted as capability one), and the transmission mode of multi-satellite data transmission that the terminal supports (denoted as capability two).

[0152] In some embodiments, the capability one refers to a maximum number of satellites that the terminal supports to connect with. In other words, the capability one is used to indicate how many satellites the terminal can connect with at most at the same time. In some embodiments, the capability one is used to determine the number of satellites that the terminal connects with at the same time. In an example, the capability one indicates that the maximum number of satellites that the terminal supports to connect with at the same time is 5, which can be understood as that the terminal can connect with 5 satellites at the same time at most. In an example, the network device can also determine the maximum value of the number of satellites that the terminal connects with at the same time based on the capability one, for example, the network device determines that the terminal connects with 5 satellites at the same time.

[0153] In some embodiments, the capability two refers to a transmission mode that the terminal supports to perform data transmission with multiple satellites. In some embodiments, the capability two is used to determine the transmission mode of the terminal to perform data transmission with multiple satellites.

[0154] In some embodiments, the transmission mode of the terminal to perform data transmission with multiple satellites can include one of the following: multi-satellite relay transmission, multi-satellite joint transmission.

[0155] In some embodiments, the multi-satellite relay transmission can be understood as that the terminal maintains simultaneous connection with multiple satellites, but the terminal simultaneously maintains data transmission with only one of the multiple satellites.

[0156] In some embodiments, the multi-satellite joint transmission can be understood as that the terminal maintains simultaneous connection with multiple satellites, but the terminal can simultaneously maintain data transmission with multiple ones of the multiple satellites.

[0157] In some embodiments, the time domain resource, frequency domain resource or transmission mode in which the terminal sends the third information can be pre-configured or configured by the network.

[0158] In some embodiments, step S2101 can also be omitted, and in this case, the network device determines the third information based on a protocol.

[0159] In step S2102, the network device sends the first information.

[0160] In some embodiments, the terminal receives the first information.

[0161] In some embodiments, the first information is used to indicate configuration information of multi-satellite data transmission.

[0162] In some embodiments, the first information can be used by the terminal to perform multi-satellite data transmission.

[0163] In some embodiments, the first information can indicate one or more configuration information. In some embodiments, the configuration information comprises at least one of the following: identification information of a satellite, transmission manner of the multi-satellite data transmission, timing information of a satellite. In an example, the identification information of a satellite can be an ID of the satellite. In an example, the timing information of a satellite can be a timing advance (TA) from a ground target reference point to the satellite or a propagation delay related information.

[0164] In some embodiments, in a case that the first information indicates one configuration information, the one configuration information can comprise at least one of the following: identification information of a satellite, transmission manner of the multi-satellite data transmission, timing information of a satellite. The one configuration information can also comprise at least one of the following: identification information of multiple satellites, transmission manner of the multi-satellite data transmission, timing information of multiple satellites.

[0165] In some embodiments, in a case that the first information indicates multiple configuration information, each of the multiple configuration information can comprise at least one of the following: identification information of a satellite, transmission manner of the multi-satellite data transmission, timing information of a satellite. Each of the multiple configuration information can also comprise at least one of the following: identification information of multiple satellites, transmission manner of the multi-satellite data transmission, timing information of multiple satellites.

[0166] In some embodiments, the network device can determine the transmitted configuration information based on the third information. That is, the network device can determine the transmitted configuration information based on the support capability of the terminal for the multi-satellite data transmission.

[0167] In some embodiments, the network device can also determine the transmitted configuration information by itself. That is, the network device determines the transmitted configuration information based on its own implementation.

[0168] In some embodiments, the first information further comprises a mapping relationship between an information field of the second information and the configuration information.

[0169] In some embodiments, the first information further comprises a mapping relationship between a first information field of the second information and the configuration information. The name of the first information field is not limited, for example, “target information field”, “specified information field”, etc.

[0170] In some embodiments, the second information is used for scheduling multiple satellites. The second information is transmitted by the network device. In an example, the second information is scheduling information.

[0171] In some embodiments, the target information field of the second information is used by the terminal to determine the configuration information used. Different values of the information field correspond to different configuration information. In the case where the configuration information contains the identification information of the satellite, the terminal can determine the scheduled satellite based on the value of the information field of the second information. In the case where the configuration information contains the transmission mode of the multi-satellite data transmission, the terminal can determine the transmission mode used based on the value of the information field of the second information. In the case where the configuration information contains the timing information of the satellite, the terminal can determine the timing information of the scheduled satellite based on the value of the information field of the second information.

[0172] In an example, the value of the information field of the second information can include: a first value (e.g., 00), a second value (e.g., 01), a third value (e.g., 10), and a fourth value (e.g., 11). The first information is used to indicate four configuration information, including: configuration information A, configuration information B, configuration information C, and configuration information D. As shown in Table 1 below, the first value indicates satellite ID1 and satellite ID2 (configuration information A), the second value indicates satellite ID3 (configuration information B), the third value indicates satellite ID1, satellite ID2, and satellite ID3 (configuration information C), and the fourth value indicates satellite ID2 and satellite ID3 (configuration information D).

[0180] In step S2104, the terminal acquires the ephemeris information of the plurality of satellites.

[0181] In some embodiments, in the case where the terminal obtains the fourth information, the terminal can acquire the ephemeris information of the plurality of satellites based on the acquisition mode indicated by the fourth information.

[0182] In some embodiments, in a case where the terminal does not obtain the fourth information, the terminal can obtain the ephemeris information of the plurality of satellites based on a default acquisition manner specified by a protocol.

[0198] In some embodiments, the satellite group can be divided according to the transmission delay information between the terminal and each satellite. In an example, the satellites with small differences in transmission delay between the terminal and each satellite can be divided into a satellite group.

[0199] In some embodiments, the satellites with transmission delay between the terminal and each satellite satisfying a preset condition are determined as a satellite group. In some embodiments, the satellites with consistent transmission delay between the terminal and each satellite can be divided into a satellite group. Alternatively, the satellites with transmission delay between the terminal and each satellite within a preset range can be divided into a satellite group. Alternatively, the satellites with transmission delay between the terminal and each satellite less than a preset threshold can be divided into a satellite group. Alternatively, the satellites with difference in transmission delay between the terminal and each satellite less than a first threshold within a first time window can be divided into a satellite group. Of course, there can be other cases for the division of the satellite group, and the above are only examples, which are not limited in the embodiments of the present disclosure. It should be noted that the preset range and the preset threshold can be set according to the performance requirement of the terminal for data transmission with the plurality of satellites, which is not limited in the embodiments of the present disclosure.

[0213] In some embodiments, in the case that the third satellite is one, the first transmission manner can be multi-satellite relay transmission. In the case that the third satellite is multiple, the first transmission manner can be multi-satellite joint transmission or multi-satellite relay transmission. If the first transmission manner is multi-satellite joint transmission, the terminal can simultaneously perform data transmission with multiple third satellites. If the first transmission manner is multi-satellite relay transmission, the terminal sequentially performs data transmission with one of the multiple third satellites.
