Description
Technical field
The present invention relates to communication technical field, and in particular to the method and device that a kind of interference is reported.
Background technology
Long Term Evolution (Long Term Evolution, LTE) system adopts OFDM
(Orthogonal Frequency Division Multiplexing, OFDM) technology, OFDM
Technology is carried the information of user by the use of the orthogonality between frequency as the mode for distinguishing user
On mutually orthogonal different carrier wave, frequency selective fading can be effective against.In addition,
Because the frequency that intra-cell users are used is mutually orthogonal, all of interference is little all from other
Area, i.e. presence of intercell interference.
5G super-intensives network is densely distributed due to cell, there are a large amount of interference sources, with legacy network
Compare, strong jamming is few in 5G networks, and weak jamming is more, most strong jamming accounting is low, and interference source is numerous,
The interference that each interference source is caused is roughly the same；Meanwhile, with increasing for small station number, network
After intensive, the overlapping region increase of cell, the interference increase of adjacent area, interfered cell is increased, net
Network dynamic increases, and causes interference with management and has more challenge.
Inter-Cell Interference Coordination (Inter Cell Interference in traditional scheme
Coordination, ICIC) and enhancement mode Inter-Cell Interference Coordination (Ehanced Inter Cell
