Abstract

A radio channel provides methods, base stations, interference inhibitory methods and receivers.Broadcast channels include one or more two -dimensional resource blocks.Multiple frequency signals and multiple data signals are combined in each resource block.System information is mapped to multiple data signals.In one embodiment, the foreign frequency signal is distributed in the configuration position to make the contemporary signal of the same resource block sent by different base stations sent by the orthogonal frequency sub -site system to reduce the conflict between the context signal.In one embodiment, the positioning position of the data signal located in the adjacent community is invalidated to reduce the conflict between the data signal and the context signal.In an embodiment, the interweaving the infrastructure signal style and signal invalidity characteristics are used to estimate the second order statistics, which helps the receiver to implement and improve the performance of the receiver.The radio channel provision method, base station, interference inhibitory method and receiver can be provided above, which can improve the quality of the channel estimation and the performance of the receiver, and it is conducive to system deployment.
