[0044] Non-Terrestrial Network (NTN) is a wireless communication system that operates above the Earth's surface. It uses satellites, high altitude platforms (HAPS), drones and other components to achieve comprehensive network coverage, especially in remote areas that cannot access traditional ground networks. Non-terrestrial networks are an important supplement to ground-based cellular communication technology. It uses the integration of satellite communication networks and ground networks to provide ubiquitous coverage capabilities, connect the multi-dimensional space of air, space, land and sea, form an integrated ubiquitous access network, and realize on-demand access in all scenarios.

[0045] Beam hopping, as a technology in satellite communications, covers a specific ground area in the form of spot beams by dynamically adjusting the direction and shape of the beam. These spot beams have a narrower coverage range than traditional fixed beams, but higher gain. The beam hopping pattern refers to the distribution and switching method of these spot beams within the satellite coverage area. The beam hopping pattern includes information such as beam direction and duration.

[0046] A beam usually includes multiple beam positions. A beam hopping position refers to the hopping of beam positions. A beam hopping pattern refers to the distribution and switching method of these beam positions in the beam coverage area. The beam hopping pattern includes information such as the cell to which the beam position points and the duration of the beam position pointing. The beam hopping period refers to the duration of a beam hopping pattern, which is equal to the time the beam remains activated.

[0047] Figure 1 Schematic diagram showing the wave hopping bit pattern of some embodiments of the present disclosure. Figure 1 As shown, a certain satellite currently has, for example, activated beam 1, activated beam 2, activated beam 3, dormant beam 4, and dormant beam 5. Taking activated beam 2 as an example, activated beam 2 includes, for example, beam position 1, beam position 2, and beam position 3. The beam hopping pattern of activated beam 2 in one beam hopping period is, for example, beam position 1, beam position 1, beam position 2, beam position 3, ..., beam position 1, beam position 1, beam position 2, beam position 3.

[0048] Figure 2 A schematic diagram showing a non-terrestrial network communication method according to some embodiments of the present disclosure. Figure 2 As shown, the non-terrestrial network communication method includes the following steps, for example: For the convenience of description, the previous hopping bit period and the current hopping bit period are named as the first hopping bit period and the second hopping bit period respectively.

[0049] In step 210, the base station determines the gain of each beam position of the beam in the first beam hopping period.

[0050] In non-terrestrial network communication scenarios, the base station can be located at a ground station or at a satellite. The base station includes, but is not limited to, a gNB (next generation Node B, i.e., a 5G base station).

[0051] In some embodiments, the revenue of each beam position of the beam in the first hopping period is determined according to at least one of the number of users, total transmission data, and unsatisfied service quality (QoS) requirements of each beam position in the first hopping period. The number of users, total transmission data, and unsatisfied service quality requirements can all represent how many business demands there are under the beam position, so that when allocating resources next time, more time, power and other resources can be allocated to the beam position with more potential business demands first.

[0052] An exemplary calculation method: using the set revenue factors of each item, performing weighted sum calculation on at least one of the number of users of each beam position in the first hopping period, the total transmission data, and the unsatisfied service quality requirement of the service, to obtain the revenue of each beam position in the first hopping period. The unsatisfied service quality requirement is determined according to the priority and service volume of each unsatisfied service.

[0053] An exemplary formula is as follows:

[0054] η i =αN1+βN2+γN3

[0055] Among them, η i represents the revenue of wave position i, N1 represents the number of users, N2 represents the total amount of transmitted data, and N3=∑ε j N j Indicates the service QoS requirements that are not met during this period, ε j Indicates the priority of service j, N j represents the business volume of business j; α, β, and γ are positive numbers, respectively representing profit factors, for example, satisfying α+β+γ=1.

[0056] In addition, when the number of users, total transmission data, and unsatisfied service quality requirements of each beam position in the first hopping bit period are not saved, or when the second hopping bit period is within the first hopping beam pattern, the number of users, total transmission data, and unsatisfied service quality requirements of each beam position in the first hopping bit period are set to preset values, that is, N1, N2, and N3 in the above formula are set to preset values. For example, these preset values ​​are 1.

[0057] In step 220, the base station allocates a hopping bit pattern for each bit of the beam in a second hopping bit period according to the revenue of each bit of the beam in a first hopping bit period, wherein the first hopping bit period is a hopping bit period before the second hopping bit period.

[0058] In some embodiments, determining the hopping pattern of each beam position includes: determining the activation duration of each beam position according to the revenue ratio of each beam position in the first hopping period; and determining the hopping pattern of each beam position according to the activation duration of each beam position.

[0059] An exemplary method for determining the activation duration of a wave position includes: allocating the beam activation time according to the revenue ratio of each wave position of the beam within the first wave position hopping period, taking the maximum value between the activation duration allocated to each wave position and the activation duration of 1 unit, and determining the maximum value or the integer of the maximum value as the activation duration of each wave position. The unit of the activation duration of each wave position includes: at least one of time slot, frame, symbol, second, millisecond, and minute. For integer units such as time slot, frame, symbol, etc., the integer of the maximum value (for example, rounding down the maximum value) is determined as the activation duration of each wave position, so that the activation duration of each wave position is a positive integer; for non-integer units such as seconds, milliseconds, minutes, etc., the maximum value is determined as the activation duration of each wave position. Thus, the activation duration is determined according to the revenue ratio, but it is ensured that each wave position has at least 1 unit of duration.

[0060] For integer units such as time slots, frames, and symbols, an exemplary formula is as follows:

[0061]

[0062] Among them, T i represents the activation duration of wave position i, ∑η represents the sum of the benefits of all wave positions under the current beam, η i represents the profit of wave position i, T beam represents the beam activation time, i.e. the duration of the beam hopping pattern, Indicates rounding down, and max indicates taking the maximum value.

[0063] For non-integer units such as seconds, milliseconds, and minutes, an exemplary formula is as follows:

[0064]

[0065] The meaning of each symbol is as mentioned above and will not be repeated here.

[0066] In some embodiments, determining the hopping pattern of each wave position of the beam according to any of the following design rules includes: the first design rule includes: the various wave positions are sorted according to the wave position sequence number, and each wave position is activated once within the wave position hopping period. In this case, the activation time of each wave position is concentrated together, and after the activation time is reached and it becomes inactive, it will not be activated again; the second design rule includes: the various wave positions are sorted according to the wave position sequence number, and each wave position is periodically activated within the wave position hopping period. In this case, the activation, inactive, active, and inactive states of each wave position will change multiple times.

[0067] Determining the hopping pattern of each beam position of the beam also includes: during the time not covered by the activation duration of each beam position, keeping it idle or randomly selecting a beam position for activation.

[0068] In step 230, the base station sends the hopping bit pattern of each bit of the beam in the second hopping bit period to the user equipment.

[0069] The hopping bit pattern of each beam bit of the beam in the second hopping bit period is sent to the user equipment under the beam coverage through high-level signaling, DCI (Downlink Control Information) or MAC (Media Access Control)-CE (Control Element) information. High-level signaling such as Radio Resource Control (RRC) signaling.

[0070] The beam-hopping pattern includes at least one of the following: an activated beam position number (set as beam position ID), an activated beam position duration (set as active duration, which may be at least one or a combination of time slot, frame, symbol, second, millisecond, minute), and a design rule number of the beam-hopping pattern (set as principle index).

[0071] For example, a new high-level signaling NTN-Beam position-Config is added to indicate the beam hopping pattern information of the current cycle. The new signaling content includes: the active beam position ID, the active beam position duration, and the beam hopping pattern design rule index.

[0072] The example format of the newly added high-level signaling is as follows:

[0073]

[0074] Among them, INTEGER represents an integer, BIT STRING represents a bit string, and OPTIONAL represents optional.

[0075] A new downlink control information is added to indicate the hopping bit pattern information of the current period. The message content of the downlink control information includes at least one of the following: the activated bit sequence number, the activated bit duration, which can be any one or a combination of time slot, frame, symbol, second, millisecond, minute, and the hopping bit pattern design rule sequence number.

[0076] A message field is added to the existing downlink control information to indicate the hopping bit pattern information of the current period. The content of the message field includes at least one of the following: the activated bit sequence number, the activated bit duration, which can be any one or a combination of time slot, frame, symbol, second, millisecond, minute, and the hopping bit pattern design rule sequence number.

[0077] A new MAC CE is added to indicate the hopping bit pattern information of the current period. The new MAC CE message content includes at least one of the following: the activation bit sequence number, the activation bit duration, which can be any one or a combination of time slots, frames, symbols, seconds, milliseconds, minutes, and the hopping bit pattern design rule sequence number.

[0078] New MAC CE format such as Figure 3 As shown, TAG Identity (TAG ID) represents the identifier of the addressing TAG (Timing Advance Group), which can occupy 2 bits. The activation wave position sequence number, the activation wave position duration, and the design rule sequence number of the wave hopping pattern are the first length, the second length, and the third length, respectively. The first length, the second length, and the third length are integer bit values, for example, the first length is 5 bits, the second length is 8 bits, and the third length is 1 bit.

[0079] In step 240, the user equipment receives the hopping bit pattern of each beam position in the hopping bit period sent by the base station, and transmits information according to the hopping bit pattern of each beam position in the hopping bit period. For example, according to the hopping bit pattern, the user equipment transmits information with the network device in the cell and duration pointed to by the beam position.

[0080] The disclosed embodiment adopts a "wavelength hopping" activation method within the activation beam, and based on the wavelength hopping pattern, implements more refined activation control with the wavelength in the beam as the granularity, further concentrates the satellite transmission power, and improves satellite coverage and business service performance.

[0081] Some application examples are listed below.

[0082] Assume that a beam includes three beam positions, namely beam position 1, beam position 2, and beam position 3. The beam activation time is 1 frame (including 10 time slots, a total of 10ms). The base station has not previously saved the number of users in each beam position, the total amount of transmitted data, and the information on the service QoS requirements that have not been met during the period. When the new beam activation time arrives, perform the following operations.

[0083] (1-1) The base station calculates the revenue of each wave position according to the revenue calculation formula: Since the base station has not previously saved the number of users at each wave position, the total amount of transmitted data, and the information on the QoS requirements of services that have not been met during the period, the parameters N1, N2, and N3 are set to the default value 1, and the calculated revenues of wave position 1, wave position 2, and wave position 3 are η1=1, η2=1, and η3=1, respectively.

[0084] (1-2) The base station determines the activation duration of the wave position according to the calculation formula of the wave position activation duration: the activation durations of wave position 1, wave position 2, and wave position 3 are calculated to be T1 = 1 / 3Tbeam 、T2=1 / 3T beam 、T2=1 / 3T beam .

[0085] (1-3) The base station determines the hopping pattern of the beam: Assuming that the hopping pattern is determined by the first design rule, the activation time unit of each beam is a time slot, and the last remaining time slot is set to an idle state, the hopping pattern is as follows: Figure 4 shown.

[0086] (1-4) The base station sends the beam hopping pattern information to the UE under the coverage of the beam. It is assumed that the newly added high-level signaling NTN-Beam position-Config is used to indicate the beam hopping pattern information of the current period. The format of the newly added high-level signaling is as follows:

[0087]

[0088]

[0089] Among them, beam position ID indicates the beam position ID, active duration indicates the activation duration, and principle index indicates the design rule.

[0090] (1-5) After the current hopping period ends, the base station counts the number of users in each hopping period, the total amount of transmitted data, and the service QoS requirements that have not been met during the period.

[0091] Assume that after the hopping period ends, the base station statistics show that the number of users in wave 1 is 2, the total amount of transmitted data is 4, and the unmet service QoS demand is 0; the number of users in wave 2 is 4, the total amount of transmitted data is 4, and the unmet service QoS demand is 1; the number of users in wave 3 is 4, the total amount of transmitted data is 4, and the unmet service QoS demand is 4.

[0092] When the next beam activation time arrives, the base station performs the following operations.

[0093] (2-1) The base station calculates the benefits of each wave position according to the wave position benefit calculation formula: According to the statistical results of the previous period, the benefits of wave position 1, wave position 2, and wave position 3 are calculated to be η1=2, η2=3, and η3=4 respectively, among which α, β, γ=1 / 3.

[0094] (2-2) The base station determines the activation duration of the wave position according to the calculation formula of the activation duration of the wave position: The activation durations of wave position 1, wave position 2, and wave position 3 are calculated to be T1 = 2 / 9T respectively. beam 、T2=3 / 9T beam 、T2=4 / 9T beam .

[0095] (2-3) The base station determines the hopping pattern of the beam: the hopping pattern is determined by using the second design rule. The activation time unit of each beam is a time slot, and the last time slot is randomly determined as beam 2. The hopping pattern is as follows: Figure 5 shown.

[0096] (2-4) The base station sends the beam hopping pattern information to the UE under the coverage of the beam. It is assumed that a new high-level signaling NTN-Beam position-Config is added to indicate the beam hopping pattern information of the current period. The format of the new high-level signaling is as follows:

[0097]

[0098]

[0099] Among them, beam position ID indicates the beam position ID, active duration indicates the activation duration, and principle index indicates the design rule.

[0100] (2-5) After the current hopping period ends, the base station counts the number of users in each hopping period, the total amount of transmitted data, and the service QoS requirements that have not been met during the period.

[0101] The disclosed embodiment adopts a "wavelength hopping" activation method within the activation beam, and based on the wavelength hopping pattern, implements more refined activation control with the wavelength in the beam as the granularity, further concentrates the satellite transmission power, and improves satellite coverage and business service performance.
