In each scene above, the frequency band that neighbor cell uses is identical, is therefore identical networking.For identical networking, can use whole system bandwidths between neighbor cell, band efficiency is far above inter-frequency networking, but presence of intercell interference can become the key factor affecting entire throughput.In the cellular radio Communication system based on OFDM (OFDM) technology, intra-cell users realizes the orthogonal with the problem solving intra-cell interference of signal by frequency division multiplexing; But as cost, identical networking can bring stronger presence of intercell interference.Therefore how to reduce presence of intercell interference, become an important subject in the wireless communication system of identical networking.In order to ensure spectrum transmissions efficiency, improve user performance in community, identical networking all adopts the Inter-Cell Interference Coordination of relative complex to suppress presence of intercell interference.
The frequency planning scheme of existing suppression co-channel interference mainly contains following several:
A kind of scheme 1:N frequency point networking method: provide N frequency point networking method, comprise the following steps: the transmitting power of adjustment assistant carrier frequency, the transmitting power of assistant carrier frequency is made to be less than the transmitting power of main carrier frequency in same community, if the assistant carrier frequency overlay area of neighbor cell is connected, then the coverage controlling assistant carrier frequency further makes covering be connected the assistant carrier frequency alien frequencies in region.Above-mentioned N frequency point networking method also comprises: the emission angle controlling assistant carrier frequency, makes the emission angle of assistant carrier frequency be less than the emission angle of main carrier frequency in same community.
