Description

Information processing method, device, equipment and computer readable storage medium

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an information processing method, an information processing apparatus, information processing equipment, and a computer-readable storage medium.

Background

For a giant constellation low-orbit satellite communication system, the dense coverage of a plurality of beams of a plurality of stars causes an overlapping coverage phenomenon, and particularly, the higher the latitude is, the more serious the overlapping coverage is. For example, referring to the constellation design considered earlier by Oneweb (18 orbital planes, 48 stars per orbital plane, 16 rectangular beams per star), although the design can keep the same orbital beam without overlapping and the equator without overlapping, as the latitude increases, there is inevitably a beam overlap between adjacent orbits, as shown in fig. 1.

The beam overlap values for different latitudes are given in table 1. As can be seen in connection with Table 1, at latitude. + -. 60. In time, the beam overlapping multiple reaches 1 time, which means that only half of the number of tracks is needed for seamless coverage; at higher latitudes, fewer orbits are required due to the greater beam overlap factor. Therefore, to ensure proper operation of the system, redundant tracks are typically closed for high altitude overlapping coverage situations. For example, in fig. 1, at 60 degrees and above latitude, the redundant track associated with track #2, etc. may be turned off.

TABLE 1

In general, the giant constellation usually performs frequency allocation of each beam according to a certain frequency reuse multiple, and the basic principle is to maintain inter-frequency between adjacent tracks. For example, taking four-color multiplexing as an example, fig. 2 shows a frequency multiplexing scheme.

It can be seen that in the medium and low latitude, the inter-beam interference is relatively small because the inter-beam interference is always configured in different frequencies between the beams of different orbits. However, in the case of high latitude of 60 degrees and above, because the partially redundant tracks are closed, the corresponding beams of the adjacent tracks of the remaining tracks will be completely in the same frequency state, and the inter-beam interference is large, as shown in fig. 3.

Examples of such adjacent tracks are co-rising or co-falling adjacent tracks. However, in the whole constellation, besides the adjacent tracks of the same ascending or descending, there is also a case that the adjacent tracks are ascending and descending, as shown in fig. 4. For the adjacent orbits with different lifting and descending, the situation of same-frequency collision inevitably exists along with the movement of the satellite. However, no technical solution in the prior art solves the interference caused by the problem, thereby resulting in poor system performance.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 5, fig. 5 is a flowchart of an information processing method provided by an embodiment of the present invention, where the method is applied to a network side device. As shown in fig. 5, the method comprises the following steps:

step 501, system configuration information is obtained, wherein the system configuration information includes beam interference information of adjacent tracks and beam overlapping information of adjacent tracks.

In the embodiment of the invention, the state change of the satellite communication system caused by the constellation operation is used as pre-configured information and is pre-configured to the network side equipment. The system configuration information may include: beam interference information of adjacent tracks and beam overlap information of adjacent tracks. The beam interference information may include co-frequency interference or inter-frequency interference, and the beam overlapping information may include whether the beams overlap or not.

For example, for medium and low latitudes (latitudes less than a predetermined latitude value, e.g., less than 60 °), inter-frequency interference between adjacent co-rising or co-falling tracks, and adjacent beam overlap of adjacent tracks is relatively small; for high latitudes (latitudes greater than or equal to a certain preset latitude value, for example greater than or equal to 60 °), when the tracks are closed, co-frequency interference exists between adjacent ascending and descending tracks (the ascending and descending directions of the adjacent tracks are the same), and the adjacent beams of the adjacent tracks are overlapped seriously; in the whole latitude range, the adjacent lifting tracks (the lifting directions of the adjacent tracks are different) have the same frequency interference.

It should be noted that, in the embodiment of the present invention, the preset latitude refers to a latitude corresponding to when the adjacent track starts to completely cover, and may be adjusted according to an actual situation.

And 502, acquiring the geographical position information of the terminal.

In this step, the network side device may obtain the geographical location information reported by the terminal.

Step 503, processing the interference suffered by the terminal according to the system configuration information and the geographical location information.

The network side equipment can determine the interference condition of the adjacent wave beams of the wave beam where the terminal is located and the overlapping condition of the wave beam where the terminal is located and the wave beam of the adjacent track according to the geographical position information and the system configuration information of the terminal, and perform corresponding processing.

Specifically, in this step, the following process may be included:

step 5031, determining whether the interference suffered by the terminal is co-channel interference.

Specifically, in the embodiment of the present invention, whether the interference received by the terminal is co-channel interference may be determined in the following two ways.

The first mode is that according to the geographical location information, a latitude area where the terminal is located is determined, and then according to the beam interference information of the adjacent tracks, under the condition that the latitude area where the terminal is located is a target latitude area, it is determined that the interference suffered by the terminal is same frequency interference. Wherein the latitude of the target latitude region is greater than or equal to a preset latitude at which adjacent tracks begin to fully cover.

According to the system configuration information described in step 501, assuming that the preset latitude is 60 °, and assuming that the latitude where the terminal is located is 50 °, it is determined that the interference suffered by the terminal is pilot frequency interference; assuming that the terminal is located at a latitude of 70 °, it can be determined that the interference suffered by the terminal is co-channel interference.

And secondly, determining a target orbit where a service satellite of the terminal is located according to the geographical position information, and determining that the interference suffered by the terminal is same frequency interference under the condition that the lifting directions of the target orbit and the adjacent orbit of the target orbit are different.

According to the geographical position information of the terminal, the information of the satellite serving the terminal and the current orbit of the satellite can be determined by combining the ephemeris information, and meanwhile, the information of the adjacent orbit can be determined, so that the lifting relation between the adjacent orbits can be judged. In this way, no matter which latitude the terminal is located, as long as it is determined according to the geographical location information that the lifting direction between the orbit of the satellite serving the terminal and the adjacent orbit of the orbit is different, it can be determined that the interference suffered by the terminal is the same frequency interference.

Step 5032, when the interference suffered by the terminal is the same frequency interference, processing the interference suffered by the terminal according to the system configuration information and the geographic location information.

In the embodiment of the invention, if the interference suffered by the terminal is pilot frequency interference, the system enters a normal working mode. If the interference suffered by the terminal is co-channel interference, the interference needs to be processed in order to ensure the system performance.

The processing of the interference experienced by the terminal may include processing in terms of resource allocation, power transmission, beam shape, and so on.

And (I) adjusting resource allocation.

In the process of adjusting resource allocation, only part of frequency domain resources of the service frequency point of the terminal are used for the service beam of the terminal, so as to ensure that the service beam of the terminal and the adjacent beam of the adjacent track are not overlapped on the frequency domain resources.

Specifically, in this step, a target orbit, a service beam, and a service frequency point where a service satellite of the terminal is located are determined according to the geographical location information. Then, according to the beam overlapping information of the target track, the service beam and the adjacent track of the target track, determining whether there is an overlapping area on a geographical area between the service beam and the adjacent beam of the adjacent track of the target track:

(1) and under the condition that no overlapping area exists, allocating a first frequency domain resource in the frequency domain resources of the service frequency point to the service beam, and allocating a second frequency domain resource in the frequency domain resources of the service frequency point to an adjacent beam of an adjacent track of the target track.

The sum of the first frequency domain resource and the second frequency domain resource is less than or equal to the total frequency domain resource of the service frequency point, and the first frequency domain resource and the second frequency domain resource are different frequency domain resources.

For example, the frequency domain resource of the service frequency point is divided into two parts: frequency domain resource 1 and frequency domain resource 2, where frequency domain resource 1 is allocated for use by the serving beam and frequency domain resource 2 is allocated for use by an adjacent beam of an adjacent track. In order to maximize resource utilization and improve system performance, the resource usage of the service beam can be preferentially guaranteed. Meanwhile, the sum of the resources of the frequency domain resource 1 and the frequency domain resource 2 may be equal to the total frequency domain resource of the service beam.

(2) Under the condition that an overlapping area exists, allocating a third frequency domain resource in the frequency domain resources of the service frequency points to the service beam, wherein the service beam and an adjacent beam of an adjacent track of the target track are in a non-overlapping area on a geographical area, and allocating a fourth frequency domain resource in the frequency domain resources of the service frequency points to the service beam, and the service beam and the adjacent beam of the adjacent track of the target track are in the overlapping area on the geographical area;

For example, the frequency domain resource of the service frequency point is divided into two parts: frequency domain resource 1 and frequency domain resource 2, wherein frequency domain resource 1 is allocated to a region of the service beam that does not overlap with an adjacent beam of an adjacent track, and the adjacent beam of the adjacent track is used, and frequency domain resource 2 is allocated to a region of the service beam that overlaps with an adjacent beam of an adjacent track. In order to maximize resource utilization and improve system performance, resource usage of the service frequency points can be preferentially guaranteed. Meanwhile, the sum of the resources of the frequency domain resource 1 and the frequency domain resource 2 may be equal to the total frequency domain resource of the serving frequency point.

And (II) adjusting the transmitting power.

In this step, the network side device may instruct the serving satellite of the terminal, or instruct the terminal to decrease the transmission power, and may also instruct the serving satellite of the terminal and the terminal to decrease the transmission power at the same time, so as to reduce the overlap with the adjacent orbit.

If the terminal determines that the transmission power of the serving satellite needs to be adjusted, in this step, the network side device may receive a first notification sent by the terminal, and instruct the serving satellite of the terminal to reduce the transmission power according to the first notification.

And (III) adjusting the beam coverage.

Specifically, in this step, the network-side device may instruct the serving satellite of the terminal to narrow the beam range to reduce the overlap with the adjacent orbit.

In the embodiment of the present invention, the manner in which the network side device instructs the service satellite of the terminal or instructs the terminal is not limited.

If the terminal determines that the beam range of the serving satellite needs to be adjusted, in this step, the network side device may receive a second notification sent by the terminal, and instruct the serving satellite of the terminal to narrow the beam range according to the second notification.

Referring to fig. 6, fig. 6 is a flowchart of an information processing method provided by an embodiment of the present invention, where the method is applied to a terminal. As shown in fig. 6, the method comprises the following steps:

step 601, obtaining system configuration information, where the system configuration information includes beam interference information of adjacent tracks and beam overlapping information of adjacent tracks.

In the embodiment of the invention, the system state change caused by constellation operation is used as a pre-configured information and is pre-configured to the terminal. The system configuration information may include: beam interference information of adjacent tracks and beam overlap information of adjacent tracks. The beam interference information may include co-frequency interference or inter-frequency interference, and the beam overlapping information may include whether the beams overlap or not.

And step 602, acquiring the geographical position information of the terminal.

In this step, the terminal may acquire its own geographical location information.

Step 603, processing the interference suffered by the terminal according to the system configuration information and the geographical location information.

The terminal can determine the interference condition of the adjacent beams of the beam where the terminal is located and the beam overlapping condition of the beam where the terminal is located and the adjacent track according to the geographical position information and the system configuration information of the terminal, and perform corresponding processing.

Specifically, in this step, the following process may be included:

step 6031, determining whether the interference suffered by the terminal is co-channel interference.

According to the system configuration information described in step 601, assuming that the preset latitude is 60 °, and assuming that the latitude where the terminal is located is 60 °, it is determined that the interference suffered by the terminal is the inter-frequency interference; assuming that the terminal is located at a latitude of 70 °, it can be determined that the interference suffered by the terminal is co-channel interference.

And 6032, processing the interference suffered by the terminal according to the system configuration information and the geographic position information under the condition that the interference suffered by the terminal is same frequency interference.

And (I) adjusting resource allocation.

And (II) adjusting the transmitting power.

In this step, the terminal may reduce the transmission power of the terminal itself, and send a first notification to the network-side device, where the first notification is used to enable the network-side device to instruct the serving satellite of the terminal to reduce the transmission power. Or the terminal may reduce its own power, or the terminal may send a first notification to the network-side device, where the first notification is used for enabling the network-side device to instruct a serving satellite of the terminal to reduce the transmission power.

And (III) adjusting the beam coverage.

Specifically, in this step, the terminal may send a second notification to the network-side device, where the second notification is used to enable the network-side device to instruct the serving satellite of the terminal to narrow the beam range.

In the embodiment of the present invention, the manner in which the terminal notifies the network side device is not limited.

The following describes embodiments of the present invention in detail with reference to specific embodiments.

For a giant low-orbit constellation, it is assumed that there are 18 orbital planes, 48 satellites per orbital plane, and 16 rectangular beams per satellite, which do not overlap with the orbital beams, and no beams overlap at the equator. The total number of the frequency points is 4, and 4-color frequency multiplexing is adopted.

In one embodiment, corresponding to fig. 2, it is assumed that the terminal is in a mid-low latitude region below 60 degrees north-south latitude of the co-ascending/co-descending orbit, served by beam #4 of satellite #1 of orbit #2, and using the #1 frequency point. Since the adjacent tracks #1 and #3 where the service beam is located are both the same ascending/descending tracks, the frequency points of the adjacent beams of the adjacent tracks of the service beam are all the different frequencies of the present beam, as shown in fig. 7. In the case of inter-frequency, the interference is relatively small, and therefore, the serving beam will be able to use all frequency domain resources of the #1 frequency point.

In one embodiment, corresponding to fig. 3, it is assumed that the terminal is in the region 60 degrees and above north and south latitude of the same ascending/descending orbit, because the beam coverage overlaps such that the orbits #2, #4, etc. are closed, and thus the terminal is served by the beam #4 of the satellite #1 of the orbit #3, using the #2 frequency point. Because the adjacent tracks #1 and #5 where the service beam is located are both the same ascending/descending tracks, the frequency points of the adjacent beams of the adjacent tracks of the service beam are all the same frequency of the present beam, as shown in fig. 8. Under the same frequency condition, the interference is large, therefore, the service beam can only use part of the frequency domain resource of the #2 frequency point to reduce the interference.

Assuming that the track #3 where the frequency point #2 is located has no overlapping coverage area with the adjacent tracks #1 and #5, the frequency domain resource of the frequency point #2 may be allocated such that the frequency domain resource of the frequency point #2 of the adjacent tracks #1 and #5 is different from the frequency domain resource of the frequency point #2 of the track # 3. For example, the frequency domain resource of frequency point #2 may be divided into two parts (frequency domain resource #1 and frequency domain resource #2) and used for adjacent tracks, as shown in fig. 9, where the frequency domain resource of frequency point #2 of track #3 is frequency domain resource #2, and the frequency domain resources of frequency point #2 of adjacent track #1 and track #5 are frequency domain resource # 1.

Assuming that the track #3 where the frequency point #2 is located has an overlapping coverage area with the adjacent tracks #1 and #5, the frequency domain resource of the frequency point #2 can be allocated. For example, the frequency domain resource of frequency point #2 may be divided into two parts: frequency domain resource #1 and frequency domain resource # 2. As shown in fig. 10, an overlapping region 1001 of beam 4 of track #3 and beam 4 of track #1 uses frequency domain resource #2, an overlapping region 1002 of beam 4 of track #3 and beam 4 of track #5 uses frequency domain resource #2, and a region 1003 of beam 4 of track #3, which is not overlapped with track #1 and track #5, uses frequency domain resource # 1.

In one embodiment, track #18 descends track #1 ascends, corresponding to FIG. 4. Assume that the terminal is served by beam #4 of satellite #1 in orbit #1, using the #1 frequency bin. Because the adjacent tracks #18 and #1 where the service beam is located have different elevation relationships, the two tracks always face the same frequency interference, where all frequency points at some time are subject to the same frequency interference, as shown in fig. 11(a) and (c), and half of the frequency points at some time are subject to the same frequency interference, as shown in fig. 11(b) and (d).

Fig. 11(a) shows that all frequency points of adjacent lifting tracks are subjected to same frequency interference at the same time (different frequency of adjacent tracks at low and medium latitudes), fig. 11(b) shows that half frequency points of adjacent lifting tracks are subjected to same frequency interference at the same time (different frequency of adjacent tracks at low and medium latitudes), fig. 11(c) shows that all frequency points of adjacent lifting tracks are subjected to same frequency interference at the same time (same frequency of adjacent tracks at high latitudes), and fig. 11(d) shows that half frequency points of adjacent lifting tracks are subjected to same frequency interference at the same time (same frequency of adjacent tracks at high latitudes).

Taking frequency point #1 as an example, the resource allocation corresponding to fig. 11(a) to (b) is as shown in fig. 12(a) and (b). In fig. 12(a), adjacent beams of adjacent tracks do not overlap in coverage. Then, the frequency domain resource of track #1 beam #4 frequency point #1 is divided into two parts: frequency domain resource #1 and frequency domain resource #2, wherein frequency domain resource #1 is allocated to be used by an adjacent frequency bin (track #18 beam # (n +1) frequency bin #1 or beam # n frequency bin #1) of an adjacent beam, and frequency domain resource #2 is allocated to be used by track #1 beam #4 frequency bin # 1. In fig. 12(b), adjacent beams of adjacent tracks overlap. Then, the frequency domain resource of track #1 beam #4 frequency point #1 is divided into two parts: frequency domain resource #1 and frequency domain resource #2, wherein frequency domain resource #1 is allocated to track #1 beam #4 for use in the region of frequency bin #1 that does not overlap with adjacent beams, track #18 and frequency bin #1 of track #1 adjacent beams (beam # (n +1) or beam # n), and frequency domain resource #2 is allocated to track #1 beam #4 for use in the region of overlap 1201 of frequency bin #1 and adjacent beams of track # 18.

Taking frequency point #1 as an example, the resource allocation corresponding to fig. 11(c) to (d) is shown in fig. 13(a) and (b). In fig. 13(a), adjacent beams do not overlap in coverage. Then, the frequency domain resource of track #1 beam #4 frequency point #1 is divided into two parts: frequency domain resource #1 and frequency domain resource #2, wherein frequency domain resource #1 is allocated to adjacent frequency bins of adjacent beams for use (frequency bin #1 of track #18 (beam # (n +1) or beam # n), and frequency domain resource #2 is allocated to frequency bin #1 of track #1 beam #4 and frequency bin #1 of track #17 (beam # (n +1) or beam # n).

In fig. 13(b), adjacent beams overlap. Then, the frequency domain resource of track #1 beam #4 frequency point #1 is divided into two parts: frequency domain resource #1 and frequency domain resource #2, wherein frequency domain resource #2 is allocated to overlapping regions (1301, 1302, 1303, etc.) of adjacent tracks for use, and frequency domain resource #1 is allocated to regions of each track that do not overlap with adjacent tracks for use (1304, 1305, 1306, etc.).

In addition to adjusting resource allocation, in the embodiment of the present invention, for the overlapping coverage condition of adjacent beams of adjacent tracks, the coverage of the beam where the terminal is located may be adjusted to avoid or reduce overlapping coverage of the beam and the beam of the adjacent track.

For example, the transmission power of the satellite corresponding to the beam and the transmission power of the terminal can be reduced, so that the uplink and downlink coverage of the beam is reduced. For example, the network-side device may instruct the satellite corresponding to the beam to decrease the transmission power, or instruct the terminal to decrease the transmission power, etc.

Alternatively, the coverage shape of the satellite beam corresponding to the beam may be adjusted so that the coverage area is smaller so as to overlap with the beams of the adjacent orbits.

It can be seen from the above that, in the embodiment of the present invention, different interference processing measures are adopted for different geographic areas, so that terminals in high-altitude areas and different lifting track areas can be protected, and better anti-interference performance can be obtained.

The embodiment of the invention also provides an information processing device.
