Description
Technical field
The present invention relates to communication technical field, more particularly to a kind of data transmission method and device.
Background technology
Between evolved base station（inter-eNodeB）Cooperative multipoint transmission（Coordinated Multi-Point
Transmission, CoMP）In scene, due to backhaul（backhaul）Can not be handed in time between the limitation of time delay and capacity, base station
Mutual all of information.It is multiple particularly when schedule information cannot be interacted in time in order to obtain CoMP gains in such a scenario
Base station may be while the independent same user equipment of scheduling（UE）, so as to improve the transmission performance of user.For this kind of UE, base station
Need to notify its multiple respective cell in base station and scheduling configuration information.For the data transfer that different base station is dispatched, used
Configuration information also can be different.
Multi-point cooperative transmission（Coordinated Multipoint Transmission/Reception, CoMP）Technology
It refer to the cooperation between the multiple transmission point on geographical position separate.In general, multiple transmission point is the base station of different districts,
Or multiple RRH of same cell base station control（Remote Radio Head）.Passed by the cooperation between multiple transmission point
It is defeated, the interference between different transfer points can be effectively reduced, improve the UE particularly handling capacities of cell edge UE.Descending multiple spot
Cooperative transmission technical scheme is broadly divided into two classes：Cooperative scheduling/wave beam forming（CS/CB, cooperative scheduling/
cooperative beamforming）And Combined Treatment（Joint processing）.
Cooperative scheduling is the coordination by the time between transfer point, frequency and space resources, it is to avoid or reduce mutual
Between interference.The interference of minizone is the principal element for restricting community marginal user performance, therefore cooperative scheduling is by reducing
The interference of minizone, can improve the performance of Cell Edge User.Combined Treatment scheme includes that dynamic transmission point switches and combines
Send two ways.In the switching of dynamic transmission point, base station can dynamically be switched to the transfer point of user's sending signal, so that often
The optimal transfer point transmission data of secondary selection.In order to realize dynamic transfer point switching, base station needs to be obtained by feedback channel
The channel information of multiple optional cells, or the channel information for obtaining optimal transmission point.Multiple transmission point in joint delivery plan
Simultaneously to user send data, with strengthen user receive signal, it would be possible to interference signal be converted into useful signal, so as to improve
The signal of user and interference and noise ratio（Signal to Interference plus Noise Ratio, SINR）.
The premise of preferable backhaul is based primarily upon to the research of CoMP technologies at present, that is to say, that can be between transfer point
Assuming that optical fiber is connected, that has no obstacle carries out information exchange, it is not necessary to consider the limitation of backhaul time delays and capacity.Now,
The A/N of user feedback channel condition informations corresponding with each transfer point（Channel State Information, CSI）Can
To carry out Combined Treatment and scheduling on the base station for concentrating on Serving cell, then according to scheduling result will need send data and
Schedule information notifies to give other each cooperation points.This preferable interaction carries out above-described various cooperative transmission technologies
Premise, so this kind of cooperation is typically all in multiple minizones of same BTS management or a macro base station coverage area
Transfer point between carry out.But if cooperative transmission is carried out between different base station, actually the backhaul between base station can not
It is ensured of preferably, it is likely that there is larger propagation delay time and capacity limit.Now, cannot be interacted in time between base station all
The information of needs, above-described cooperative transmission technology particularly joint processing technology, it may be difficult to implement.Needed in this scene
Some other cooperative transmission technologies are considered, so that user remains able to obtain the gain of multipoint cooperative, this kind of cooperative transmission
Technology is referred to as " inter-eNodeB CoMP ", wherein comparing typically multi-flow multi-process transmission technology.
Descending multi-flow transmission plans allow multiple base stations concurrently and independently to dispatch a user, so as to improve user
Transmission performance, and each cell resource utilization, its basic skills is two cells with respective resource and with confidence
Cease to dispatch user, user simultaneously detects and respective feedback the schedule information and transmission data of multiple cells.The program
Substantially flow it is as follows：
Serving BS determines that user uses the transmission plan of multi-flow, and interactive user and each base station between base station
Information；
User data distribution is carried out between each base station；
Each base station independently carries out user scheduling；
Control channel and corresponding data transfer of the user in a subframe respectively to each process are detected, and are measured
The channel information of each base station, feeds back CSI information and A/N information.
Each base station receives the confirmation from user（ACK）And CSI feedback, and independently carry out mixed automatic retransfer（HARQ,
Hybrid-ARQ）Control；
Wherein, each base station carries out the link of descending control/data transfer to user and is referred to as a transmission process respectively（It is right
An arrow in Ying Yutu）.From the point of view of user terminal, a process then corresponds to a down control channel and downlink data letter
Road；From the point of view of base station end, a process then corresponds to a cell.Base in the base station of participation cooperation where user attaching cell
Stand and be referred to as between serving BS or Serving cell, the base station for cooperating referred to as cooperative base station or cooperation cell, these base stations
It is co-operating relation.The base station/cell of cooperation can have one or more, typically only one of which cooperative base station end
Situation.Generally, user carries out blind check by the corresponding down control channel in multiple base stations respectively, to obtain multiple bases
Stand respective schedule information, so as to be detected to the downlink data that multiple base stations are transmitted respectively according to schedule information.
