The integral multiple of bandwidth.
There are one control resource collections for each cell for user's initial access, broadcast system information etc., is named as public
Resource collection is controlled, the public control resource collection of neighboring community there can be different configurations；Specifically, the public control in neighboring community
Resource collection can be on different control resource collection, i.e., different physical time-frequency resources, and each controls resource collection
There are different controlling symbols numbers or mapping mode；
The configuration information of public control resource collection can be sent by PBCH, including：Bandwidth, physical resource position, control
Symbol numbers processed, mapping mode etc.；Wherein, mapping mode or other configurations can also be realized by preset configuration relevant way；
User group common control channel is located in public control resource collection, the physical time-frequency money that it is located in different community
It source position can be different；Specific location information can be bound with cell ID, implicit to realize.
So as to which so that control resource collection need not occupy system bandwidth, it is complicated can effectively to reduce control blind Detecting
Degree；Distributed mapping is used between control resource collection, higher frequency diversity gain can be provided；
The public control resource collection of neighboring community can be located at different running time-frequency resources, can reduce inter-cell interference,
Promote the robustness of control channel；User group common control channel in each cell can be located at different running time-frequency resources, can
To reduce inter-cell interference；Specific instruction is bound with cell ID, and stealth is realized, signaling overheads can be reduced.
The above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, without departing from the principles of the present invention, it can also make several improvements and retouch, these improvements and modifications
It should be regarded as protection scope of the present invention.
