Description
Technical field
The present invention relates to the communications field, in particular to a kind of multipoint cooperative dispatching method and device.
Background technology
With the development of communication service and the growth of people's demand, following wireless communication system needs to provide higher speed
Rate, higher spectrum efficiency and more inexpensive service.
Advanced long-term evolution system (Long-Term Evolution Advance, referred to as LTE-Advance) is as
Third generation partnership project (3rd Generation Partnership Project, referred to as 3GPP) long term evolution (LTE)
Evolution technology, by 3GPP organize receive.
One of target of LTE-A exactly improves system, particularly in the spectrum efficiency of cell edge and throughput.It is former
Because being, lte-a system be with Orthogonal Frequency Division Multiplexing (Orthogonal Frequency Division Multiplexing,
Referred to as OFDM) frequency division systems of the system for basic multiple access multiplexing mode.Frequency spectrum resource is efficiently used in order to obtain, this is
System major part is the system that channeling is 1, i.e. neighboring community uses identical frequency.Such configuring condition, Intra-cell because
Completely orthogonal between carrier wave, almost without interference problem, but the interference problem in cell edge minizone becomes quite tight
Weight.Therefore, LTE-A is proposed using coordinated multipoint transmission technology (Coordinated Multiple Point
Transmission and Reception, referred to as CoMP) it is gulped down as a kind of improvement high data rate covering and cell edge
It spits rate and/or the means of system throughput can be improved in high load, low-load.
CoMP refers to when user equipment (User Equipment, referred to as UE) is in multiple cell edges, by multiple
Community associated coordination, scheduling to UE progress multipoint datas transmission/reception or by multiple minizones, it is small so as to reach elimination
Section interference, the purpose for improving signal quality and data throughput.In the description of current 36.814 frames of 3GPP TR, CoMP points
For two categories below：
(1) Combined Treatment (Joint processing, referred to as JP)：User data can be in collaboration set each station
Point obtains；
(2) cooperative scheduling (Coordinated Scheduling, referred to as CS)/wave beam forming (Coordinated
Beamforming, referred to as CB)：User data is only sent by serving cell, but its scheduling/beamforming scheme is by cooperating
The multiple cooperation cells concentrated determine.
Serving cell：Physical Downlink Control Channel (Physical Downlink Control are sent to mobile station
Channel, referred to as PDCCH) cell, only there are one serving cell in communication process.
In current non-cooperating cell, the channel quality of with good grounds user, transmission block number, stand-by period, history are handled up
The dispatching method that the factors such as rate, logical channel type carry out, e.g., a kind of typical proportional fair scheduling is according to user
Historical throughput, logical channel type and transmission block number determine the scheduling factor of user, so as to according to each user scheduling because
Son carries out priority ranking, and then carries out scheduling of resource to user.The calculating of scheduling factor can represent SF with equation belown=
f(Channel Qualityn, TB Numbern, waiting timen, history throughputn, Logical
Channel typen...).The formula represent for user n scheduling factor calculate by its channel quality, transmission block number,
The factors such as stand-by period, historical throughput and logical channel type determine.
But the user of multipoint cooperative sending method, particularly JP modes are used for business datum, due to business datum
It is sent simultaneously by multiple cooperation cells, each cell will be scheduled the user, if each cell is considered alone to user
Scheduling, then it is possible that different community is inconsistent to same dispatching priority of users, so as to influence the transmission of data.Cause
This, participating in multiple cells of cooperation needs the user to use unified dispatching method.In addition, normal conditions, participate in cooperation
Number of cells is more, the throughput of UE can improve it is more, but due to the resource of the multiple cells of the user occupancy, system
Average throughput can be affected, and in such cases, selection be needed to carry out rational management to user so that being assisted to the user
The average throughput of system will not significantly reduce after sending.
