In the mobile communication network, more and more higher to the requirement of data rate and coverage rate, macro base station is adopted to provide the method for access can not meet require that of data rate and coverage rate, therefore, for improving data rate and coverage rate, mainly adopt cell splitting at present, hot zones or in some low power base station of indoor deployment (as HeNB (Home enhanced Node Base Station, Home eNodeB), Pico NB (slight macro station), Relay NB (relay base station) etc.), low power base station is that one is applied in family room's environment, working environment, or the base station equipment under other little overlay environment, more high data rate is provided, the more business of low cost.

Although the introducing of low power base station improves data rate and coverage rate to a certain extent, but the interference in system can be caused relative to even more serious same layer network, especially the interference problem on control channel has become the bottleneck with heterogeneous network work frequently, how to ensure that the receptivity on each channel then becomes problem demanding prompt solution in heterogeneous network.In order to ensure that system can normally work, adopt some strategies avoided interference to coordinate mutual interference at present, but employ these tactics the interference imbalance that may cause different resource, can have a great impact the measurement mechanism in same layer network; User may adopt different interference average modes to obtain CQI (Channel Quality Indicator, channel quality information), and disturb being chosen at of average mode to affect AMC (Adaptive Modulation and Coding to a great extent, Adaptive Modulation and Coding) selection, and user may be caused not by existing test case.
