Description
Technical field
The present invention relates to field of communication technology more particularly to a kind of cooperation resource determining method and devices.
Background technique
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 becomes main interference.It is dry how minizone is reduced
It disturbs, realizes that identical networking becomes a main problem of LTE and LTE-A.In order to be further reduced the co-channel interference of minizone,
Using the side of cooperative multipoint transmission (Coordinated Multiple Points Transmission/Reception, CoMP)
Formula reduces inter-cell interference, the spectrum efficiency of lifting system, the especially performance of Cell Edge User equipment.Edge is used
Family equipment and central user equipment, industry is generally by existing to user equipment in the signal strength of this cell and the user equipment
The signal strength of adjacent cell measures, when the user equipment this cell signal strength and the user equipment in adjacent cell
When the difference of signal strength is less than preset threshold value, which is divided into edge customer equipment, otherwise, centered on division
User equipment.
CoMP technology is generally directed to edge customer equipment, and CoMP technology is related to the concept of cooperation bandwidth, or is known as
Cooperate resource, and cooperation resource defines the scope of resource of a cooperation, participates in the user equipment of CoMP in cooperation scope of resource
Scheduling, the user equipment for being not involved in CoMP are dispatched in non-cooperating scope of resource, handle the gain for advantageously ensuring that CoMP in this way,
And the scheduling resource of center of serve user equipment is unaffected.
Current scheme is static configuration cooperation resource, passes through user equipment/traffic load/modulating-coding side to existing net
Formula (Modulation and Coding Scheme, MCS) accounting etc. is investigated, and provides the cooperation resource size of recommendation.So
