Description
Technical field
The present invention relates to communication technical field, more particularly to a kind of cooperation resource determining method and device.
Background technology
For Long Term Evolution (Long Term Evolution, LTE) system and advanced Long Term Evolution (Long
Term Evolution Advanced, LTE-A) for system, inter-cell interference turns into main interference.
How inter-cell interference is reduced, realize that identical networking turns into a LTE and LTE-A subject matter.
In order to further reduce the co-channel interference of minizone, using cooperative multipoint transmission (Coordinated Multiple
Points Transmission/Reception, CoMP) mode reduce inter-cell interference, lifting system
The performance of spectrum efficiency, particularly Cell Edge User equipment.Set for edge customer equipment and central user
It is standby, industry typically by user equipment in the signal intensity of this cell and the user equipment in adjacent cell
Signal intensity is measured, when the user equipment this cell signal intensity and the user equipment in adjacent cell
Signal intensity difference be less than default threshold value when, the user equipment is divided into edge customer equipment, it is no
Then, it is divided into central user equipment.
CoMP technologies are generally directed to edge customer equipment, and CoMP technologies are related to the concept of cooperation bandwidth,
Or it is referred to as cooperation resource, cooperation resource defines the scope of resource of a cooperation, participates in CoMP user
Equipment is dispatched in cooperation scope of resource, is not involved in CoMP user equipment and is adjusted in non-cooperating scope of resource
Degree, so handles and advantageously ensures that CoMP gain, and center of serve user equipment scheduling resource not
