Description

An information processing method, device and readable storage medium

technical field

The present application relates to the field of communication technologies, and in particular, to an information processing method, an apparatus, and a readable storage medium.

Background technique

In recent years, giant constellations characterized by low orbits have grown rapidly. Generally, due to various factors such as power, satellite communication payloads tend to use beam hopping.

Mega constellations are usually built in stages. As shown in Figure 1 and Figure 2, it is a schematic diagram of the coverage elevation angle and terminal scan angle of the satellite before and after the expansion of the constellation. In the initial construction stage of the constellation (referred to as "original constellation"), due to the continuous coverage formed by the small number of satellites, the capabilities of the corresponding satellites and terminals need to be stronger. , 0°～B1), the terminal has a scanning angle with a larger scanning range (-A1～-90°, 90°～A1); in the later construction stage of the constellation (referred to as "expansion constellation"), because the number of satellites increases, For the continuous coverage formed, the capabilities of the corresponding satellites and terminals can be weakened, that is, the elevation angle of satellite coverage (-B2～0°, 0°～B2) can be reduced (ie B2<B1), and the range of terminal scanning (-A2～- 90°, 90°～A2) can also be reduced (ie A2>A1). The cost of the satellite will decrease as the elevation angle covered by the satellite decreases, and the cost of the terminal will decrease as the range scanned by the terminal decreases. Therefore, the expansion of the constellation can reduce the terminal cost, thereby promoting the maturity of the industry.

As shown in Figures 3(a) and 3(b), after the expansion of the constellation system, the coverage of each satellite under the original constellation system needs to be reduced to reduce the interference caused by the overlapping coverage of adjacent satellites. For satellite communication systems using beam hopping, the reduction of satellite coverage means that the wave position of beam hopping needs to be changed, that is, the wave position of the original coverage area needs to be adjusted to the wave position of the new coverage area. Changes in the number of waves will affect both the network and the terminal. Therefore, it is necessary to take corresponding measures to solve this problem to ensure normal communication.

Referring to FIG. 4, FIG. 4 is a flowchart of an information processing method provided by an embodiment of the present application, as shown in FIG. 4, including the following steps:

Step 401: The network device of the satellite communication system sends beam information to the terminal, where the beam information includes:

The total number of wave bits of the beams supported by the satellite communication system, the number of beams, the frequency point information of each beam, the number of wave bits corresponding to each beam, the dwell time of the beam in each wave position, the beam in the wave position scan pattern.

Among them, the wave position refers to the coverage area of the beam on the earth's surface in a specific direction. The beam may be a control beam or a service beam.

For example, for control beams, in practical applications, for a low-orbit satellite communication system using beam hopping, after the constellation system performs the same-layer orbit and co-frequency expansion, in order to ensure normal communication, the network device can send the control beam information to the terminal , the information of the control beam includes:

The total number of wave bits of the control beam supported by the satellite communication system, the number of control beams, the frequency information of each control beam, the wave number corresponding to each control beam, and the residence time of the control beam in each wave position , which controls the scanning pattern of the beam at the wave position.

Among them, the maximum number of wave positions (L _max ) corresponding to the control beam needs to reflect the maximum wave position that all low-orbit satellites can support before and after the expansion. The actual number of wave positions (L) can be flexibly adjusted and satisfies 1≤L≤L _max .

In particular, if there is only one control beam, the network device can send to the terminal the number of waves corresponding to the control beam, the dwell time of the beam at each wave position, and the scanning pattern of the beam at the wave position.

The number of wave positions supported by a single control beam may be different before and after expansion, and the number of wave positions supported by multiple control beams may be the same or different.

In practical applications, the network device may send the information of the beam to the terminal in a broadcast manner, or may also agree with the terminal about the information of the beam.

As shown in Figure 5, it is assumed that the satellite system supports a coverage of 112 wave positions during initial construction. After the subsequent expansion, because the actual coverage of each satellite is reduced, the satellites in the original system can no longer support 112 wave positions, but only need to support the coverage of 72 wave positions. Therefore, the satellite system needs to determine two parameters about the number of wave positions corresponding to the control beam, one is the maximum value of the wave position corresponding to the control beam (L _max =112), and the other is the wave position corresponding to the supported control beam number (L=72), and L can be broadcast to the terminal through a system message.

In this embodiment of the present application, the scanning pattern of the beam at the wave position includes the geographic adjacent relationship between the beams at different wave positions, and may not include the geographic adjacent relationship between the beams at the different wave positions. If not included, the network device may further send indication information to the terminal, where the indication information is used to indicate information about adjacent wave positions of the wave position corresponding to the beam where the terminal is currently located. The geographical adjacent relationship between different wave positions refers to the geographical position relationship between adjacent wave positions. For example, the information of a certain wave position A and its adjacent wave positions in the south, southeast, east, northeast, north, northwest, west, and southwest directions may constitute the geographic adjacency relationship.

For the case of a single control beam, as shown in FIG. 6 , a wave position scanning pattern of the control beam is shown. Assuming that the dwell time of the control beam in each wave position is 3ms, then the control beam completes one round of scanning of all wave positions. The 112 wave positions in the original constellation system need 3ms×112=336ms. 72 waves need 3ms×72=216ms.

For the case of multiple control beams, as shown in FIG. 7 , a wave position scanning pattern of two control beams is shown. Assuming that the dwell time of the control beam in each wave position is 3ms, then the control beam completes one round of scanning of all wave positions. The 112 wave positions in the original constellation system need 3ms×(112/2)=168ms. Under the expanded constellation 72 waves require 3ms×(72/2)=108ms.

In practical applications, the scanning pattern of the beam at the wave position includes the index number of the beam at the wave position and the service time of the beam at the wave position; or, the scanning pattern of the beam at the wave position includes the index number of the beam at the wave position, the beam position The time of service at the wave positions and the geographic proximity of the beams between the different wave positions.

In this embodiment of the present application, the scanning pattern of the beam at the wave position may be embodied in the form of a wave position scanning list. As shown in Table 1, the mapping relationship between the wave position index number and the service time (or referred to as scan time) of the beam in the wave position is shown.

Table 1

Of course, the wave position scanning list can also be recorded in a two-dimensional manner, as shown in Table 2, the scanning pattern can not only reflect the mapping relationship between the wave position index number and the service time of the beam in the wave position, but also reflect the wave position Geographical adjacency between bits. Therefore, for any wave position, the adjacent wave positions corresponding to different azimuths can be clearly known.

Table 2

Through the obtained scanning pattern, the terminal can determine the search and detection window of the wave position signal based on the wave position scanning table, and can start the RRM (Radio resource management, radio resource management) measurement of the adjacent wave position based on the current wave position number. Moreover, in this way, resources can also be saved because the number of bits occupied by the pattern is controllable.

In the embodiment of the present application, the network device of the satellite communication system sends beam information to the terminal, so that the terminal can determine the timing relationship of downlink signals according to the wave position information corresponding to the currently resident beam and the information of the beam , thus ensuring normal communication.

Referring to FIG. 8, FIG. 8 is a flowchart of an information processing method provided by an embodiment of the present application, as shown in FIG. 4, including the following steps:

Step 801: The terminal determines the wave position information corresponding to the currently residing beam by searching after the terminal is turned on.

After the terminal is powered on, it first searches for and resides in one of the beams, and obtains the wave position index number corresponding to the beam. In the original satellite system, because the number of satellites is small, the satellites correspond to a larger coverage area, which also means that the terminal needs to support a larger search angle. After the expansion, the satellite corresponds to a smaller coverage area, which also means that the terminal only needs to support a smaller search angle. For existing terminals, if each satellite search is always carried out according to the larger search angle range that can be supported, on the one hand, the satellite search time is too long, and on the other hand, the satellite with the best quality may not be connected. In order to solve this problem, the terminal can use the priority search method in the search star to reduce the search complexity.

Specifically, the terminal may perform a search according to a historical search angle, and select a currently camped beam according to the search result and determine the wave position information corresponding to the currently camped beam. The historical search angle may be the search angle adopted in the previous search, and so on. Alternatively, the terminal may also perform a search according to the historical beam coverage information, and select the currently camped beam according to the search result and determine the wave position information corresponding to the currently camped beam. For example, the network can notify the terminal of the maximum wave number or the maximum coverage angle, and then the terminal can derive the search angle of the terminal based on the information notified by the network, and search within the range of the search angle preferentially.

For example, it is assumed that the minimum search elevation angle of the terminal under the original satellite system is 10°; after the capacity expansion, the minimum search elevation angle of the terminal is 30°. If the terminal of the original satellite system always searches for satellites according to its capability range [10°～90°, -90°～-10°], then the terminal is in [10°～30°, -30°～-10°]. Searching for intervals is a waste of time. Therefore, the terminal will record the angle of each successful star search. After a period of training, the terminal can judge by itself that the minimum elevation angle of the terminal's successful star search is 30°, then in the subsequent star search, the terminal only needs to be in the range [30 °～90°, -90°～-30°] to search for stars. Or, the network notifies the terminal of the maximum coverage angle of the satellite under the expansion constellation, and the terminal calculates the minimum elevation angle of the satellite under the maximum coverage angle of the satellite to be 30°, and only needs to be in the range [30°～90°, -90°～-30°] to search for stars.

Step 802, the terminal acquires information of the beam.

The information of the beam may be preset or sent by a network device. Therefore, in the next step, the terminal may receive the information of the beam sent by the network device of the satellite system; or obtain the information of the preset beam. Wherein, the information of the beams includes: the total number of beams supported by the satellite communication system, the number of beams, the frequency information of each beam, the number of waves corresponding to each beam, the standing position of the beam in each wave Stay time, the scanning pattern of the beam in the wave position.

Step 803: The terminal determines the timing relationship of the downlink signal according to the wave position information corresponding to the currently camping beam and the information of the beam.

Optionally, in the information of the beam, the scanning pattern of the beam at the wave position may include the geographic adjacent relationship between the beam at different wave positions. At this time, the terminal may determine the timing relationship of the downlink signals according to the information of the adjacent wave positions.

If the scanning pattern of the beam at the wave positions does not include the geographic proximity of the beam at different wave positions, the network device may send this information to the terminal. Correspondingly, the terminal can receive the indication information sent by the network device of the satellite system, where the indication information is used to indicate the information of the adjacent wave positions of the wave position corresponding to the beam where the terminal is currently located. At this time, the terminal determines the time sequence relationship of the downlink signals according to the wave position information corresponding to the beam that the terminal currently resides on and the information of the adjacent wave positions of the wave position corresponding to the beam where the terminal is currently located.

Specifically, in the process of determining the timing relationship of the downlink signal, the terminal obtains the information of the adjacent wave positions based on the wave position index number where it is located and the geographical adjacent relationship between the beam positions in different wave positions, and according to the beam position in each wave position Information such as the dwell time of each wave position determines the timing relationship of the downlink signal, thereby ensuring control processes such as data transmission and handover.

As shown in FIG. 9 , assuming that the terminal currently resides on wave position #1, the network device can notify the terminal of the adjacent wave position information of the wave position where the terminal is located (for example, wave positions #2 to #9 next to wave position #1) , so that the terminal can perform targeted measurement, which is beneficial to handover. That is, for the handover caused by satellite movement, the terminal can measure in advance based on the known adjacent wave position information, which not only avoids the complexity of blind measurement, but also shortens the measurement time; the terminal scans based on the wave position and the known wave position. information, can quickly perform wave synchronization and measurement operations.

In the embodiment of the present application, the network device of the satellite communication system sends beam information to the terminal, so that the terminal can determine the timing relationship of downlink signals according to the wave position information corresponding to the currently resident beam and the information of the beam , thus ensuring normal communication. For a low-orbit satellite communication system using beam hopping, the solutions of the embodiments of the present application do not need to perform software and hardware upgrade processing, so the implementation is simple.

It should be noted that the method of the present invention is also applicable to a ground communication system using beam hopping.
