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 embodiment of the present invention provides a method and device for satellite system resource allocation, wherein the method includes: the base station receives the request information of the terminal; determines the channel type and the number of time slots TsLen according to the request information; Count TsLen and preset resource allocation mode, traverse all the carriers of the spot beams of the satellite system, and generate a target carrier list; sort the carriers in the target carrier list according to the preset rules to obtain the carrier with the highest priority; set the priority The highest carrier is determined as the target carrier; TsLen consecutive time slots are allocated to the terminal on the target carrier. By applying the embodiment of the present invention, a target carrier list can be generated according to a preset resource allocation mode, and the carriers in the target carrier list are Priority sorting, obtaining the carrier with the highest priority, determining the carrier with the highest priority as the target carrier, and allocating time slots on the target carrier can realize the optimal allocation of satellite system resources.

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...
