Problems solved by technology

[0005] The existing resource allocation method is mainly to improve the utilization rate of wireless resources, such as the utilization rate of time slots. However, the satellite system is a system with limited downlink transmission power. The existing resource allocation method only ensures that all carriers correspond to The total power of the same time slot does not exceed the maximum downlink transmit power of the spot beam, and there is no corresponding technical solution for how to better reduce the downlink transmit power of the entire spot beam

Abstract

The embodiments of the invention provide a method and a device for resource allocation of a satellite system. The method comprises the following steps: a base station receives request information froma terminal; the channel type and the time slot number TsLen are determined according to the request information; all the carriers of the point beam of the satellite system are traversed and a targetcarrier list is generated according to the channel type, the time slot number TsLen and a preset resource allocation mode; the carriers in the target carrier list are sorted by priority according to apreset rule to obtain the carrier with the highest priority; the carrier with the highest priority is determined as a target carrier; and TsLen continuous slots are allocated for the terminal on thetarget carrier. According to the embodiments of the invention, the target carrier list is generated according to the preset resource allocation mode, the carriers in the target carrier list are sortedby priority to obtain the carrier with the highest priority, the carrier with the highest priority is determined as the target carrier, and time slots are allocated on the target carrier. Therefore,optimal allocation of the resources of the satellite system can be realized.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for allocating satellite system resources. Background technique [0002] The satellite system is a communication signal that uses satellites as relay stations to communicate between multiple ground stations. The main purpose of satellite communication is to achieve "seamless" coverage of the ground. [0003] In recent years, time-division multiple access technology has been widely used in satellite communications, that is, multiple ground stations occupy the same frequency band, but occupy different time slots. Compared with the frequency division multiple access method, the time division multiple access multiplexing technology will not produce intermodulation interference, does not need to use up and down conversion to separate the signals of each earth station, is suitable for digital communication, and can allocate transmission bandwidth according to...
