Description
Technical field
The present invention relates to the communications field, in particular to a kind of collocation method and device of different-frequency measure parameter.
Background technology
In order to satisfy the demand of growing large bandwidth high-speed mobile access, third generation partnership project (Third Generation Partnership Projects, abbreviation 3GPP) releases senior Long Term Evolution (Long-Term Evolution advance is called for short LTE-Advanced) standard.LTE-Advanced is for Long Term Evolution (Long-Term Evolution, abbreviation LTE) evolution has kept the core of LTE, and adopted on this basis a series of technology that frequency domain, spatial domain are expanded, to reach purposes such as improving the availability of frequency spectrum, increase power system capacity.
Usually, wireless communication system is in order on a large scale for the user provides radio communication, to need to dispose the large base station of coverage.This base station is commonly referred to macro base station (Macro), and the residential quarter of its covering is commonly referred to Hong Qu (Macro Cell).Simultaneously, consider user's different demands and different environments for use, need to be for the user provide higher-quality radio communication service under some environment or scene, the base station that some coverages are little, transmitting power is lower thereby be used.These small base stations comprise little base station (Pico) and Home eNodeB (HeNB).
Because macro base station and little base station, Home eNodeB coverage difference are huge, may be deployed with a large amount of little base station and Home eNodeB in the coverage of Hong Qu.The load that little base station can be carried out coverage enhancement and share grand station, and Home eNodeB can be used for improving indoor telecommunication service quality.At Macro, under the concurrently deployed heterogeneous network scene of pico and HeNB, can occur with each the internodal interference problem that covers.
Shown in the scene among Fig. 1 (a), the macro transmitting power is much larger than pico, causes macro to the interference of the descending reception of pico boundary user, and the high-power terminal in macro edge is to the interference of pico near.And under the scene in Fig. 1 (b), if HeNB belongs to closed user group (Closed Subscriber Group is called for short CSG), then HeNB can cause interference near macro user.In order to solve the interference problem of the above-mentioned two kinds of scenes of heterogeneous network, 3GPP has started the research of eICIC (enhanced Inter-cell Interference Coordination) at R10, be intended to adopt the mode of time-division to solve with each the internodal interference problem that covers.
