Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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, but 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.
For satellite communication systems, different terminal types have large differences in capabilities, which leads to different considerations for different terminals in system design, and further introduces complexity in system design. For a satellite communication system designed based on the ground 5G standard, the existing terminal capability reflects information such as maximum rate, channel bandwidth and transmission power, but lacks information related to satellite communication characteristics, such as terminal antenna type, terminal application scenario, terminal visual range, terminal moving speed, terminal transmitting antenna equivalent aperture, terminal receiving antenna equivalent aperture, terminal transmitting maximum EIRP, terminal receiving G/T, terminal maximum scheduling bandwidth, terminal minimum access bandwidth, and the like. Since information related to the communication characteristics of the satellite can reflect the capability of the terminal, the lack of such information can cause difficulty in system design. For example, different types of terminal antennas mean different measurement methods adopted by the system, a terminal using a phased array antenna can support cross-satellite measurement, a terminal using a single parabolic antenna does not support cross-satellite measurement, and the system can select different terminal measurement methods according to different types of antennas; the different application scenes of the terminals mean that the maximum Doppler frequency offset which can be resisted by the terminals are different, generally, the airborne terminal has higher Doppler frequency offset resistance compared with a vehicle-mounted terminal, and the system can select different random access channel parameters and the like according to the application scenes of the terminals.
Based on the terminal type parameters, the terminal capability required by the satellite communication system design is provided, so that the system design can be compatible with various terminal types, and the related parameters can be configured in a self-adaptive manner, so that the complexity of the system design is reduced.
The present invention will be specifically explained below.
As shown in fig. 1, which is a flow chart of steps of a system design method according to an embodiment of the present invention, the method includes the following steps:
step 101: and determining the terminal type parameter.
In this step, specifically, since the terminal type can reflect the main characteristics of the satellite terminal, the terminal type parameter can be used as a newly added terminal capability parameter, so that the satellite communication system can perform targeted system design according to the terminal type parameter, and the system design is simpler and more efficient.
In addition, specifically, the terminal type parameter can reflect a difference between terminals, and in this case, the terminal type parameter includes at least one of the following factor items:
the method comprises the steps of terminal antenna type, terminal application scene, terminal visual range, terminal communication rate, terminal moving speed, terminal transmitting antenna equivalent aperture, terminal receiving antenna equivalent aperture, terminal sent maximum equivalent omnidirectional radiation power (EIRP), terminal received equivalent temperature gain coefficient (G/T), highest signal-to-noise ratio supported by the terminal, maximum scheduling bandwidth of the terminal and minimum access bandwidth of the terminal.
In this way, by determining at least one factor item in the above as the terminal type parameter, the main characteristics of the satellite terminal can be reflected based on the factor items, so that the system design is simpler and more efficient when the terminal type parameters are input as the system design of the satellite communication system.
Step 102: and carrying out system design on the satellite communication system based on the terminal type parameter.
In this step, specifically, after the terminal type parameter is determined, the system design is performed on the satellite communication system based on the determined terminal type parameter.
At the moment, the satellite communication system is subjected to system design based on the determined terminal type parameters, and the capability of the terminal can be reflected based on the correlation between the terminal type parameters and the satellite communication characteristics, so that the system design can be simpler and more efficient when the satellite communication system is subjected to system design according to the terminal type parameters, and the problem of system design difficulty caused by the lack of the terminal type parameters in the conventional terminal capability is solved.
It should be noted that, in the above factor items, if a first factor item cannot be obtained according to other factor items, that is, cannot be derived according to other factor items, the first factor item may be used as the determined terminal type parameter, that is, the factor item is a necessary option of the determined terminal type parameter; in addition, if the second factor item can be obtained, i.e. can be derived, according to other factor items, the second factor item may be used as an option for the determined terminal type parameter, i.e. the determined terminal type parameter may not include the second factor item.
For example, the present embodiment may use the terminal antenna type, the terminal application scenario, and the terminal visible range as the necessary options of the terminal type parameter, that is, the terminal type parameter at least includes the terminal antenna type, the terminal application scenario, and the terminal visible range.
In addition, the terminal communication rate, the terminal moving speed, the equivalent aperture of the transmitting antenna of the terminal, the equivalent aperture of the receiving antenna of the terminal, the maximum EIRP sent by the terminal, the G/T received by the terminal, the highest signal-to-noise ratio supported by the terminal, the maximum scheduling bandwidth of the terminal, and the minimum access bandwidth of the terminal may be used as a necessary option for the terminal type parameter, or may be used as a selectable option for the terminal type parameter, which is not specifically limited herein.
In addition, further, after determining the terminal type parameter, the embodiment may notify the terminal and the network side of the terminal type parameter through a broadcast channel, a control channel, or a traffic channel, so that both the terminal side and the network side can obtain a unified terminal type parameter.
In addition, further, in this embodiment, when the system design is performed on the satellite communication system based on the terminal type parameter, at least one of the following design manners may be included:
firstly, when the terminal type parameter includes the terminal antenna type, whether the terminal supports the cross-satellite measurement is determined based on the terminal antenna type.
Specifically, the terminal type parameter includes a terminal antenna type, so that whether the terminal supports cross-satellite measurement can be determined based on the terminal antenna type in the measurement process, and parameter design in the measurement process in the satellite communication system is realized.

Specifically, the terminal type parameter includes a terminal application scenario or a terminal moving speed, so that in the HARQ process, HARQ can be selectively started or stopped according to the terminal application scenario or the terminal moving speed, and parameter design of the HARQ process in the satellite communication system is realized.
And thirdly, when the terminal type parameter comprises a terminal visual range, determining a star searching range and a star following range of the terminal based on the terminal visual range.
Specifically, the terminal type parameter comprises a terminal visual range, so that the satellite searching range and the satellite tracking range of the satellite communication system can be determined based on the terminal visual range, and the parameter design of the cell initial searching process and the normal communication process in the satellite communication system is realized.
And fourthly, when the terminal type parameter comprises the terminal communication rate, the maximum scheduling bandwidth of the terminal or the minimum access bandwidth of the terminal, determining the preamble length and the subcarrier interval of the random access channel based on the terminal communication rate, the maximum scheduling bandwidth of the terminal or the minimum access bandwidth of the terminal.
Specifically, the terminal type parameter includes a terminal communication rate, a maximum scheduling bandwidth of the terminal, or a minimum access bandwidth of the terminal, so that a preamble length and a subcarrier interval of a random access channel of the satellite communication system can be determined based on the terminal communication rate, the maximum scheduling bandwidth of the terminal, or the minimum access bandwidth of the terminal, thereby realizing parameter design for an access process in the satellite communication system.
Therefore, by determining the terminal type parameters related to the terminal characteristics, the system parameters such as the cell initial search process, the access process, the measurement process, the HARQ process and the like of the satellite communication system can be designed based on the terminal type parameters, and the simplicity and the high efficiency of the system design are realized.

if the communication rate of the terminal is less than 20Mbps, the maximum scheduling bandwidth of the terminal is less than 20MHz, or the minimum access bandwidth of the terminal is less than 10MHz, the random access channel is selected to be 839 × 5KHz or 139 × 30KHz, that is, the preamble length is 839, the subcarrier interval is 5KHz, or the preamble length is 139, and the subcarrier interval is 30 KHz.
For another example, in example 6, if the terminal type parameter includes EIRP, the highest signal-to-noise ratio supported by the terminal, the terminal communication rate, the maximum scheduling bandwidth of the terminal, and the like may be calculated based on the terminal type parameter, which is specifically described as follows:
the highest signal-to-noise ratio supported by the terminal is related to EIRP and G/T, and then the highest signal-to-noise ratio is determined according to the link budget;
