3GPP is researching non-terrestrial network (Non Terrestrial Network, NTN) technology, which typically employs satellite communication to provide communication services to terrestrial users. Satellite communications have many unique advantages over terrestrial cellular communications. First, satellite communications are not limited by the user region, for example, general land communications cannot cover areas where communication devices cannot be installed, such as oceans, mountains, deserts, etc., or communication coverage is not performed due to rarity of population, while for satellite communications, since one satellite can cover a larger ground, and the satellite can orbit around the earth, theoretically every corner on the earth can be covered by satellite communications. And secondly, satellite communication has great social value. Satellite communication can be covered in remote mountain areas, poor and backward countries or regions with lower cost, so that people in the regions enjoy advanced voice communication and mobile internet technology, and the digital gap between developed regions is reduced, and the development of the regions is promoted. Again, the satellite communication distance is far, and the cost of communication is not obviously increased when the communication distance is increased; and finally, the satellite communication has high stability and is not limited by natural disasters.

NTN technology may be combined with various communication systems. For example, NTN technology may be combined with NR systems into NR-NTN systems. For another example, NTN technology may be combined with an internet of things (Internet of Things, ioT) system into an IoT-NTN system. As an example, ioT-NTN systems may include NB-IoT-NTN systems and eMTC-NTN systems.

In order to facilitate understanding of the technical solutions of the embodiments of the present application, the following description is given of related technologies of the embodiments of the present application, and the following related technologies may be optionally combined with the technical solutions of the embodiments of the present application as an alternative, which all belong to the protection scope of the embodiments of the present application.

In order to improve the utilization rate of resources, a novel broadband satellite system generally adopts a beam hopping technology, and can allocate resources in four dimensions of space, time, frequency and power so as to adapt to the dynamic change of ground services. Some technical schemes surrounding the beam hopping resource allocation are mostly oriented to the scene of the same beam as the broadcast, and the network control center establishes global resource scheduling according to the service application of each user to obtain the optimal time slot number allocated to each beam.

Individual schemes take the form of decoupling the broadcast beam from the traffic beam. By setting a narrow bandwidth beam for the broadcast beam, the satellite may provide greater coverage to achieve a faster user access experience, unlike a broadband narrow beam for the traffic beam.

The technical scheme related to the jump beam resource allocation focuses on the scene of the tight coupling of the service beam and the broadcast wave, considers the time slot resource allocation based on the service application resource number, the interference among beams and the service priority, and does not consider the jump beam satellite scene that the broadcast beam and the service beam are independent of each other. In the scene of decoupling service beams and broadcast beams considered by the existing network, the broadcast beams access wave positions in a one-by-one polling mode, and the method has the defects of long access period and low system utilization rate. Therefore, the technical scheme of the embodiment of the application considers that the wave position characteristic value is established based on factors such as the number of regional users, the regional priority, the satellite-ground co-channel interference and the like, the wave position characteristic value is mapped into the access frequency of the broadcast wave beam in each wave position, and a hopping rule is formulated according to the access frequency of each wave position. Therefore, the hopping rule of the broadcast beam is dynamically adapted to the wave position characteristic, and the method has the advantages of improving user experience, improving the utilization rate of the system, reducing satellite-ground co-channel interference and the like.

On the other hand, interference coordination schemes facing the same frequency of the star and the ground are mostly focused on allocating different frequency beams to wave positions to avoid interference, and frequency spectrum resources are increasingly tense, so that the schemes can lead to larger frequency spectrum resource waste. Therefore, the technical scheme of the embodiment of the application provides a dynamic satellite-to-ground co-frequency interference coordination scheme with low system overhead, which is applied to a satellite-to-ground high co-frequency scene.

In summary, the technical solution of the embodiment of the present application at least solves the following problems: firstly, the number of satellite broadcast beams is limited, and the number of service wave bits is large, so that the problem of long polling period of the broadcast beams is caused; secondly, due to the non-uniform characteristics of the user and the service distribution, the problem that the overall experience of the system is reduced due to the fact that a broadcasting beam adopts a one-by-one polling mode. In addition, the technical scheme of the embodiment of the application provides a coordination scheme for avoiding satellite-ground co-channel interference based on the proposed hopping rule.

In order to facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies may be optionally combined with the technical solutions of the embodiments of the present application, which all belong to the protection scope of the embodiments of the present application. Embodiments of the present application include at least some of the following.

According to the technical scheme, the broadcasting beam hopping scheme for the hopping beam satellite system is provided, the wave position characteristic value of each wave position is calculated based on the factors such as the number of real-time users, the regional QoS characteristics, the satellite-ground co-channel interference and the like, and the hopping rule of the broadcasting beam is formulated according to the wave position characteristic value, so that broadcasting information can be acquired more quickly for downlink synchronization in a hot spot region, a high-priority service aggregation region and a region with low satellite-ground co-channel interference, service communication is further carried out as soon as possible, and user experience is improved. Meanwhile, the scheme informs the ground base station of the access time of the satellite broadcast beam in advance so as to realize the avoidance of the same-frequency interference.

It should be noted that, in the embodiments of the present application, the description about "hopping rule" and the description about "hopping scheme" may be replaced with each other.

It should be noted that, in the embodiments of the present application, the description of the "base station" may refer to "ground base station" unless otherwise specified.

For example, for one wave bit, satellite signal interference intensities of multiple base stations corresponding to the wave bit may be summed to obtain the co-channel interference intensity of the wave bit. For a plurality of wave positions, the same-frequency interference intensity of each wave position in the plurality of wave positions can be obtained in the mode.

As an example, the first statistical time may be aΔt, where a is a positive integer much greater than 1, and is an adjustment coefficient for matching the statistical time with the region change time. Δt is the time the broadcast beam has polled all the bins one time.

As an example, the second statistical time may be zxaΔt, where z > 2.

According to the scheme, the calculation frequency of the jump rule can be reduced by prolonging the statistical time, and the calculation force waste is avoided.

The flow associated with fig. 6, 9, and 10 is illustrated in the following with reference to specific application examples. The method comprises the following specific steps:

(1) The broadcast beam is in wave position N according to the wave beam jump rule _n Broadcasting system information (such as SSB, SIB1, other SI and Other system information and synchronizing signals), the terminal completes the downlink synchronization of frequency and time, and acquires a series of system information. In the system initialization stage, the broadcast beam is according to N ₁ 、N ₂ ……N _N The time it takes for the broadcast beam to poll all the bins one by one is assumed here to be deltat.

(2) After broadcasting the broadcast beam, the list P of wave-position information devices starts information collection with a statistical time aΔt, where a is a positive integer much greater than 1, and is an adjustment coefficient for matching the statistical time with the regional variation time.

Wave position N _n The corresponding user number sequence is used as a counter to count the wave position N in the time period _n User number U initiating random access in _n 。

Second, wave position N _n When the terminal in the list establishes PDU session through satellite, the wave bit N in the list P _n In the corresponding QoS column, the counter of each priority will count the QoS distribution of traffic within aΔt. General purpose medicineDifferent weights are set for each priority, and are mapped into regional QoS characteristic values Qn according to the statistical data.

Further, let the wave position N _n B ground base stations are shared, an interference coordinator deployed on the base stations can send information to satellites once in each statistical period, and the interference intensity I of satellite signals received by the base station B is reported _n，b Wave bit N in list P _n The corresponding co-frequency interference column is used as a counter to count all co-frequency interference intensities I existing in the wave position in the A delta T counting period _n 。

As an example: regional QoS characteristic value Q _n Including but not limited to the methods exemplified by the examples. Assuming that a technical mode based on DSCP priority is adopted, X _0，n ～X _7，n The service numbers corresponding to each priority level initiated by the wave position in A delta T are calculated according to the data counted by the QoS counter to obtain the regional QoS characteristic value Q _n The specific calculation method is as follows:

wherein k is ₀ ～k ₇ The weights corresponding to the priorities of BE, AF 1-AF 4, EF, CS6 and CS7 are respectively from small to large.

As an example: intensity of co-channel interference I _n Including but not limited to one of the following calculations:

I _n ＝∑ _b I _n，b ＝∑ _{b&and In, b > -10dB} (P _n，Rec -G _{r, interference coordinator} +G _r，b -S _r，b )

Wherein P is _n，Rec Is the actual measured satellite RSRP of the interference coordinator; g _{r, interference coordinator} 、G _r，b Gain for receiving antennas of the interference coordinator and the base station; s is S _r，b The sensitivity is received for the base station.

(3) After all wave positions are counted for A delta T, the wave position information device obtains the number U of users _n Regional QoS characteristics Q _n Intensity of co-channel interference I _n Three influencing factors, calculating the characteristic value R of each wave position _n Mapping to the frequency of each wave bit. Wherein the wave position characteristic value R _n Positive correlation with the number of users and the regional QoS characteristics and negative correlation with the co-channel interference of the wave position.

As an example: specific calculation methods of the wave-position characteristic value include, but are not limited to, the following two methods:

omega is the number U of the regulated users _n Regional QoS characteristics Q _n Intensity of co-channel interference I _n And the weight factors of influencing factors.

Setting threshold values thr1 and thr2, when R _n When thr1 is less than or equal to N _n Frequency F of (2) _n =1; when thr1 < R _n When the value is less than or equal to thr2, the N is allocated to _n Frequency F of (2) _n =2; when thr2 < R _n When assigned to N _n Frequency F of (2) _n =3; the total number of accesses is: f= Σf _n 。

(4) And (3) distributing the access sequence of each wave bit according to the access frequency and the total access times of each wave bit calculated in the step (3), namely designing a wave beam hopping scheme. The design principle is as follows: for a wave bit with multiple access frequencies, the front and back accesses should be avoided as closely as possible.

As an example: a method for allocating an access order of each wave bit according to an access frequency includes, but is not limited to, one of the following:

every time, starting from the most frequent wave position

Flower arrangement is carried out at intervals of a margin, and ROUND [ a,0]Refer to rounding a to return an integer. The example assumes a total number of accesses of 13, a wave position of 7, The frequencies are 1,1,3,2,1,2,3 respectively, and the access sequence of each wave bit, namely the beam hopping rule is:

TABLE 2

(5) The first broadcast beam hopping cycle after the new hopping rule is obtainedAnd in the period, the broadcast beam temporarily does not adopt a new hopping rule, and the beam access is carried out according to the original hopping rule. Upon beam access, the broadcast beam will broadcast a new hopping rule to the co-channel interference value I _n Not 0 (if the calculated new hopping rule is consistent with the original hopping rule, the information need not be broadcast).

The interference coordinator on the ground base station calculates the next access time interval according to the original hopping rule by default. However, when the interference coordinator located on the ground base station receives the new hopping rule broadcasted by the satellite, the new and old hopping rules are combined (when the system is in the initialization stage, the hopping rule defaults to N ₁ 、N ₂ ……N _N ) The time interval that the present wave bit will be accessed next is calculated.

As an example: let N be an example ₁ ，N ₃ For co-channel interference bands, the new beam hopping rule is shown in table 2, and the old hopping rule is shown in table 3, assuming that the time of the broadcast beam at each band is Δt. When there are no new and old hopping rules, N ₁ 、N ₃ The wave bits will be accessed again at intervals 7 Δt. And when N ₁ When the interference coordinator of the wave bit receives the new jump rule, after 13 delta t time is calculated, the broadcast wave beam can access N again ₁ 。

(6) The interference coordinator on the ground base station informs the base station of the calculated access time interval information, the base station prepares resources for interference avoidance for the next satellite beam access in advance, and the resource allocation scheme can be agreed by two different systems in advance.

On the premise that the ground base station knows the next access time of the satellite wave beam, when the satellite wave beam accesses the wave bit with the same-frequency interference, the ground base station and the satellite are divided in a finer granularity on the frequency band, the ground base station and the satellite are orthogonal in frequency use, and when the satellite wave beam leaves the wave bit, the ground system and the satellite system recover the full-frequency band resource use.

(7) In the second broadcast beam hopping period after the new hopping rule is obtained, the broadcast beam accesses the wave position by adopting the new hopping rule. The proposal repeats steps (1) - (7), and the list P of the wave position information device starts a new round of information statistics.

The number of users U obtained in the step (3) _n Zone QoS characteristics Q _n Intensity of co-channel interference I _n Information such as the value of the regional characteristics of each wave bit over a period of time, which values change less in most cases, resulting in less frequent changes in the hopping rule of the broadcast beam. If the jump rule is updated and calculated only according to the steps, the calculation force is wasted. Therefore, if the hopping rule of the broadcast beam is unchanged for y statistical periods, the statistical time of the counter of the wave-position characteristic list is changed to zxaΔt (y, z are preset values, y, z > 2). After the wave position characteristic list collects the data of the latest statistical period, R is obtained according to the step (3) _n And R 'obtained after collecting the data of the previous statistical period' _n Comparing whether the two are in the same threshold interval (R _n Averaging operation based on statistical time). R when all wave positions _n 、R′ _n If the two are in the same threshold interval, the beam hopping rule is unchanged, and the counter maintains zxADeltaT; if the time is in different threshold intervals, updating the jump rule according to the step (4), and recovering the statistical time of the counter to ADeltaT. By prolonging the statistical time, the calculation frequency of the wave position information device is reduced, and the waste of calculation power is avoided.

The technical scheme of the embodiment of the application provides the following scheme: a broadcast beam hopping scheme and a satellite-to-ground co-channel interference coordination scheme. For the broadcast beam hopping scheme, on one hand, a wave position information device is introduced, and the wave position information device stores a plurality of information such as the number of users, the regional QoS characteristics, the same-frequency interference intensity and the like corresponding to each wave position respectively into a wave position characteristic list P by collecting the information, and calculates the beam hopping rule associated with each wave position characteristic; on the other hand, a scheme for generating broadcast beam hopping rule is proposed, when all wave bits are counted by ADeltaT, the user number U in each wave bit for a longer time is calculated according to the information stored in the wave bit information device _n Regional QoS characteristics Q _n Intensity of co-channel interference I _n Weighting it to obtain characteristic value R of wave position _n Mapping the access frequency of each wave position in the wave beam hopping period to obtain a new broadcast wave beam hopping rule; in yet another aspect, the area characteristic value is less variable in most cases, the broadcast beam hopping rule may not change for a longer time, and a scheme of extending the statistical period is adopted to reduce the computational waste. For the satellite-ground co-frequency interference coordination scheme, on one hand, a frequency coordination device is introduced, and each base station is provided with an interference coordinator aiming at a sparse ground network in a satellite coverage area, so that the interference coordinator can communicate with a ground base station and a satellite; on the other hand, a scheme of satellite-ground co-channel interference coordination is provided, and in the first broadcast beam hopping period after obtaining the new hopping rule, the broadcast beam will broadcast the new hopping rule to the co-channel interference value I _n 0. The interference coordinator calculates the time interval of the next access of the broadcast beam to the present wave bit according to the wave beam hopping rule, and informs the base station. Base stationAnd performing interference avoidance in the next satellite beam access, namely performing orthogonality on frequency use by the satellite-ground two systems according to a pre-agreed scheme. When the satellite beam leaves, both sides resume the full frequency band use.

According to the technical scheme, the wave position characteristic value of each wave position is calculated based on the factors such as the number of real-time users, the regional QoS characteristics and the satellite-ground co-channel interference, and a broadcast wave beam hopping scheme is formulated according to the wave position characteristic value, so that more access frequencies and shorter access time intervals are provided for hot spot regions, high-priority regions and regions with low co-channel interference. The method has the following advantages: the wave position characteristic list design has the advantages of low storage capacity and strong real-time performance; the wave position access frequency is hooked with a plurality of influencing factors such as the number of users, the service priority, the same-frequency interference and the like, so that the problem that the system experience is low due to the adoption of a conventional polling mode is solved, the user experience is improved, and the satellite-ground same-frequency interference is reduced; aiming at the problem that the regional characteristic value is small in change in most cases and the broadcast beam hopping rule is not changed for a long time, a scheme for prolonging the statistical period is adopted to reduce the calculation power waste.

According to the technical scheme of the embodiment of the application, according to the hopping rules of the period and the next period, the interference coordinator calculates and informs the base station of the time interval of the next access of the broadcast beam. The base station and the satellite wave beam are subjected to frequency orthogonality according to a pre-agreed resource allocation scheme, so that interference avoidance is realized, and the scheme has the following advantages: under the scene of high consistency of satellite-ground system frequency bands, satellite-ground co-channel interference avoidance is realized; the interference avoidance operation is carried out during the beam access, and the two systems recover the use of the full frequency band when the beam leaves, so that the scheme has high dynamic property, and compared with a method for distributing different frequency beams to the wave positions, the resource utilization rate is improved.
