[0241] In one implementation, the cooperative communication method is, for example, a formation method, a non-formation method, a formation plus a non-formation method (formation + non-formation method), or a formation plus a formation method (formation + formation method).

[0242] In one implementation, the method of cooperative communication can be indicated by the way the ephemeris number is set in the ephemeris number information.

[0243] In one implementation, when the ephemeris numbers of multiple network devices are all in the same set, the cooperative communication method used is indicated as a formation method.

[0244] For example, in Figure 4 Based on the implementation example, the ephemeris number information can be represented as {SA, SB}, where SA is the ephemeris number of network device A and SB is the ephemeris number of network device B.

[0245] In one implementation, when the ephemeris numbers of multiple network devices are not in the set, the indicated cooperative communication method is a non-grouping method. For example, in... Figure 5 Based on the implementation example, the ephemeris number information can be represented as: SA, SB, where SA is the ephemeris number of network device A and SB is the ephemeris number of network device B.

[0246] In one implementation, when some of the ephemeris numbers of multiple network devices are in one set and others are not in the set, the cooperative communication method used is indicated to be a formation + non-formation method.

[0247] For example, in Figure 6 Based on the embodiment, the ephemeris number information can be represented as: SA, {SB1, SB2}, where SA is the ephemeris number of network device A, SB1 is the ephemeris number of network device B1, and SB2 is the ephemeris number of network device B2.

[0248] In one implementation, when the ephemeris numbers of multiple network devices are in different sets, the cooperative communication method used is indicated as a grouping + grouping method.

[0249] For example, in Figure 7 Based on the embodiment, the ephemeris number information can be represented as: {SA1, SA2}, {SB1, SB2}, where SA1 is the ephemeris number of network device A1, SA2 is the ephemeris number of network device A2, SB1 is the ephemeris number of network device B1, and SB2 is the ephemeris number of network device B2.

[0250] In this embodiment, the terminal device sends beam capability information to the first network device. The first network device can know the beam capability of the terminal device through the beam capability information and instruct the terminal device to use multiple network devices, so that the terminal device can communicate collaboratively with at least two of the multiple network devices, thereby improving the communication quality between the network devices and the terminal device.

[0251] In one embodiment, the communication method provided in this application includes at least one of S201 to S203.

[0252] For example, the communication method provided in this application may include S202 and S203, but not S201.

[0253] Without S201, the terminal device is required to report beam capability information by default. With S201 included, the terminal device reports beam capability information upon receiving a beam capability request.

[0254] Based on the above embodiments, the communication method provided in this application embodiment will be described using the example of at least two network devices excluding the first network device.

[0255] Figure 3 This is the third flowchart illustrating the communication method provided in this application. Figure 3 As shown, the method includes:

[0256] S301. The first network device sends a beam capability request message to the terminal device.

[0257] S302. The terminal device sends beam capability information and the terminal device's mobility information to the sending beam capability request information.

[0258] The mobility information of the terminal device is used by at least two network devices to generate beams directed at the terminal device.

[0259] In one implementation, the mobility information can be Global Navigation Satellite System (GNSS) information.

[0260] In one implementation, the movement information includes one or more of the following: location information, movement speed, or movement direction.

[0261] S303. The first network device sends ephemeris number information to the terminal device based on beam capability information and the terminal device's mobility information.

[0268] S305. The terminal device identifies at least two network devices among multiple network devices based on the tracking duration of each network device.

[0269] In one implementation, where the first network device is not included among at least two network devices, at least one network device other than the first network device can be identified among multiple network devices.

[0270] The tracking duration for each of the multiple network devices is either a valid time or a preset invalid information;

[0272] Preset invalid information can also be called predefined invalid values.

[0273] The meaning of the default invalid information is that the terminal device cannot generate a beam pointing to the corresponding network device.

[0274] In one implementation, at least two network devices or at least one network device are identified as network devices whose tracking duration is valid among a plurality of network devices.

[0275] In one implementation, at least two network devices, or at least one network device, may be network devices whose effective time is greater than or equal to a preset time threshold. The preset time threshold may be a time threshold predetermined by the protocol.

[0276] In one implementation, at least two network devices, or at least one network device, may be a preset number of network devices with the longest valid time among the candidate network devices. The preset number may be a number predetermined by the protocol.

[0277] The candidate network devices can be network devices whose validity period is greater than or equal to a preset time threshold.

[0283] The duration of tracking by the terminal device for each of at least two network devices; or...

[0284] The minimum tracking duration among the tracking durations of at least two network devices by the terminal device.

[0285] In one implementation, the tracking time information can be represented as: {T i}, where i = 0, ... (N E -1), where N E T represents the total number of network devices. i This represents the tracking duration for the i-th network device among multiple network devices.

[0286] In one implementation, the tracking time information can also be represented as: {T i ’}, where j = 0, ... (N E ’ -1), where N E ’ T represents the total number of at least two network devices. i ’ This represents the tracking duration for the j-th network device out of at least two network devices.

[0287] In one implementation, the tracking time information can also be represented as: {T min}, where T min Indicates the minimum tracking duration.

[0288] S308. The first network device generates a beam pointing towards the terminal device based on the tracking time information and the movement information of the terminal device.

[0289] In one implementation, the first network device determines the minimum tracking duration in the first information and generates a beam pointing to the terminal device and lasting for the minimum tracking duration based on the terminal device's movement information.

[0290] In one implementation, the first network device generates a beam that points to the terminal device and lasts for a preset duration based on the terminal device's movement information.

[0291] In one implementation, the preset duration can be the time agreed upon in the protocol or the time configured by the first network device.

[0292] S309. The first network device sends tracking time information and terminal device movement information to at least two network devices.

[0293] S310, Each of at least two network devices generates a beam pointing towards the terminal device based on tracking time information and the movement information of the terminal device.

[0294] In one implementation, each of at least two network devices determines a minimum tracking duration in the tracking time information and generates a beam pointing towards the terminal device and lasting for the minimum tracking duration based on the terminal device's movement information.

[0297] In one embodiment, the communication method provided in this application includes at least one of S301 to S311.

[0298] In one implementation, one or more steps in S301 to S311 can be split, combined, or the order of some steps can be changed to obtain a new communication method.

[0299] In one implementation, one or more steps from S301 to S311 can be omitted to obtain a new communication method. For example, S301, as well as S308, S310, and S311, can be omitted.

[0300] In one implementation, the duration of the cooperative communication is determined based on two factors: satellite-to-ground transmission delay and the minimum tracking duration among the tracking durations of the terminal device for each second network device.

[0305] The information processing latency of network devices (t3); or,

[0306] Information processing delay of terminal equipment (t4).

[0307] In one implementation, the satellite-to-ground transmission delay is the sum of the satellite-to-ground uplink transmission delay, the satellite-to-ground downlink transmission delay, the information processing delay of the network device, and the information processing delay of the terminal device. For example, T... delay = t1 + t2 + t3 + t4.

[0308] In one implementation, the satellite-to-ground transmission delay is the product of a first transmission coefficient and the satellite-to-ground uplink transmission delay, the information processing delay of the network device, and the information processing delay of the terminal device. For example, T... delay =K1×t1+t3+t4, where K1 represents the first transmission coefficient, and the value of K1 can be, for example, 2, or other values.

[0309] In one implementation, the satellite-to-ground transmission delay is the product of the second transmission coefficient and the satellite-to-ground uplink transmission delay, the information processing delay of the network device, and the information processing delay of the terminal device. For example, T... delay =K2×t2+t3+t4, where K2 represents the second transmission system, and the value of K2 is, for example, 2.

[0310] In one implementation, the satellite-to-ground transmission delay can also be the transmission delay predicted by an artificial intelligence model based on the satellite-to-ground uplink transmission delay, satellite-to-ground downlink transmission delay, information processing delay of network devices, and information processing delay of terminal devices.
