Abstract

Embodiments of the present invention provide a carrier selection method, a base station, and a terminal device of a communication system, relate to the field of mobile communication, and can realize the coordinated use of frequencies between base stations of multi-standard and multi-carrier. The method is as follows: first, the base station obtains the base station information of all adjacent base stations and the equipment information of all terminal equipment within the signal coverage, then measures and counts the interference situation of the uplink and downlink and screens out candidate carriers, and finally according to a specific resource allocation scheme. Candidate carriers are allocated. The embodiment of the present invention is used for the coordinated use of frequencies among base stations of multi-standard and multi-carrier.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a carrier selection method of a communication system, a base station and terminal equipment. Background technique [0002] LTE (Long Term Evolution, long-term evolution) system can be divided into FDD-LTE (Frequency Device Duplexing LTE, Frequency Division Multiplexing LTE) system and TDD-LTE (Time Device Duplexing LTE, Time Division Multiplexing LTE) system according to the physical layer transmission mode. With the development of communication technology, the base station equipment of the wireless communication system is evolving towards a multi-mode base station. [0003] For a traditional single-mode multi-carrier communication system, the carrier selection between base stations mainly obtains the carrier configuration of adjacent base stations through the interface between base stations (such as the X2 interface), and obtains the carrier frequency and bandwidth by...
