Abstract

Embodiments of the present invention provide a method, device, and base station for selecting a carrier. The method includes: the first base station obtains carrier information of a cell under the second base station; and the first base station selects a carrier application according to the obtained carrier information. In the embodiment of the present invention, when base stations of various forms can support multiple carriers, it is possible to know the interference situation of adjacent cells on all carriers, reduce inter-cell interference to the greatest extent, and improve system capability. It avoids interference information that can only be coordinated between cells of the same frequency, and realizes interference coordination of all cells under all carriers.

Description

technical field

[0001] The invention relates to a wireless communication system, in particular to a method, device and base station for selecting a carrier. Background technique

[0002] With the development of mobile broadband, the bandwidth requirements of end users are greatly increased, and the existing macro network-based networking mode will not be able to meet the bit rate required by mobile broadband services. In order to further improve the system capacity, more low-power access points or small base stations (hereinafter collectively referred to as small base stations) can be introduced within the scope of the macro network to improve the system capacity. The transmit power of the small base station is smaller than that of the macro base station, so the downlink coverage is much smaller than the downlink coverage of the macro base station. Taking the Long Term Evolution (LTE, LongTerm Evolution) system as an example, the home base station (Home eNodeB), micro base ...
