Description

The transmission method and device of information between a kind of base station

Technical field

The present invention relates to wireless communication technology field, the transmission method and device of information between more particularly to a kind of base station.

Background technology

Multi-point cooperative transmission（Coordinated Multipoint Transmission/Reception, CoMP）Technology Refer to the cooperation transmission between detached multiple transmission point on geographical position.In general, the plurality of transfer point can be different Multiple remote radio-frequency heads of the base station control of the base station of cell, or same cell（Remote Radio Head, RRH）. By the cooperation transmission between multiple transmission point, the interference between different transfer points can be effectively reduced, improve user equipment （User Equipment, UE）The particularly handling capacity of Cell Edge User equipment.Wherein, descending multi-point cooperative transmission technology master Including：Cooperative scheduling/wave beam forming（CS/CB, Cooperative SchedulingBeamforming）And Combined Treatment （Joint Processing）.

Cooperative scheduling refers to the coordination by the time between transfer point, frequency and space resources, it is to avoid or reduce passing Interference between defeated point, as the interference of minizone is the principal element of restriction Cell Edge User equipment performance, therefore cooperates with Scheduling can pass through the interference for reducing minizone, to reach the purpose of the transmission performance for improving Cell Edge User equipment.Joint Process includes dynamic transmission point switching mode and joint sending method, wherein, in dynamic transmission point switching mode, base station can be moved State switches to the transfer point of user equipment sending signal, so as to select the transfer point of optimum to believe for the user device transmissions every time Number；In order to realize dynamic transfer point switching, base station needs the channel information that multiple optional cells are obtained by feedback channel, or Person obtains the channel information of optimal transmission point.In joint sending method, multiple transmission point sends data to user equipment simultaneously, with Strengthen user equipment receive signal ability, due to can with will likely interference signal be converted into useful signal, so as to improve The letter of user equipment is dried ratio（Signal-to-Interference and Noise Ratio, SINR）.

At present, the research of CoMP technologies is mainly used in preferable passback（backhaul）Scene under, that is to say, that, it is assumed that Can be connected using optical fiber between transfer point, and can the clog-free interaction for carrying out each information of milli, without considering The restriction of backhaul time delays and capacity.Under the application scenarios, the response/non-response of user equipment feedback （Acknowledgement/Non-acknowledgement, A/N）Information and the corresponding channel condition information of each transfer point （Channel State Information, CSI）, the base station of the Serving cell of the user equipment can be concentrated on（Base is serviced Stand）On carry out Combined Treatment and scheduling, then according to scheduling result by need send data and schedule information notify to other Each cooperation point（That is cooperative base station）.This preferable information exchange is the premise for carrying out above-mentioned various cooperative transmission technologies, institute It is typically all in multiple minizones of same BTS management or multiple in same macro base station coverage area with this kind of cooperation Carry out between transfer point.

But, if cooperative transmission is carried out between different base station, due to the backhaul between base station it cannot be guaranteed that being reason Think, it is likely that there is larger propagation delay time and capacity limit.Now, institute's letter in need cannot be interacted between base station in time Breath, above-mentioned cooperative transmission technology are particularly joint processing technology, it may be difficult to implement.Under the scene, need to consider some other Cooperative transmission technology so that user equipment is obtained in that the gain of multipoint cooperative, and this kind of cooperative transmission technology is referred to as “inter-eNodeB CoMP”（Multi-point cooperative transmission between base station）, wherein comparing typically multi-flow（Multi-process）Pass Transferring technology.

In descending multi-flow transmission technologys, it is allowed to which same user equipment is concurrently and independently dispatched in multiple base stations, from And the resource utilization of the transmission performance and each cell of the user equipment is improved, shown in Figure 1, base station 1 can with base station 2 Concurrently and independently to dispatch UE1；The basic skills of the technology is：Two cells are adjusted using respective resource and configuration information Same user equipment is spent, it is anti-with corresponding that the user equipment carries out detection simultaneously to the schedule information and transmission data of multiple cells Feedback.According to the high-speed slender body theory currently studied（High Speed Downlink Packet Access, HSDPA）In multi-flow schemes and carrier aggregation（Carrier Aggregation, CA）In inter-eNB CA sides Case, and with reference to the application scenarios of CoMP, the flow process that can obtain the descending multi-flow transmission plans is as follows：

Serving BS determines that user equipment uses the transmission plan of multi-flow, and interaction user equipment between base station And the information of each base station；

User data distribution is carried out between each base station；

Each base station independently carries out the scheduling of user equipment；

Control channel of the user equipment in a subframe respectively to each process and corresponding data detect that measurement is each The channel information of base station, and to the corresponding CSI and A/N information of each base station feedback；And

The CSI and ACK information of each base station receive user equipment feedback, and independently the user equipment is carried out mixing automatically Repeat requests（Hybrid Automatic Repeat Request, HARQ）Control.

In descending multi-flow transmitting procedures, if serving BS occurs to become for the configuration information that user equipment is provided Change, when serving BS needs new configuration information to be notified to cooperative base station by backhaul connections, it may be necessary to when longer Between so that the configuration information is notified time to user equipment and notifies to differ to the time for assisting base station by serving BS Cause；If the configuration information of cooperative base station changes, need new configuration information to be notified to clothes by backhaul connections Business base station, then by serving BS downlink signaling notifying user equipment, the time delay size that the process is produced is at cooperative base station end It is to be difficult to estimate.In addition, if between the base station cooperation carried out by uplink, such as carries out joint reception, in addition it is also necessary to interaction A/N The information to delay sensitive such as information.

At present, the connection of X2 interface or the foundation of S1 interfaces based on backhaul can be passed through between base station, and is connect by X2/S1 The protocol stack and corresponding signaling of mouth carries out information exchange.The connection set up by X2 interface is referred to as into X2 connections generally, will be passed through The connection that S1 interfaces are set up is referred to as S1 connections, wherein, X2 bonding pads point control plane and user plane are respectively used to application protocol The Deta bearer of the signaling bear and user data of message；X2 connections can complete to include the mobility switching of user equipment, base The interference coordination of load management, minizone between standing, X2 interface management and fault processing, user equipment tracking, application layer data The functions such as interaction, mobility parameters management, energy-conservation.The X2 that multi-to-multi annexation can be set up between base station connects, therefore necessarily Assume that in region.As X2 connections are related to multiple layers of process, therefore when processing Prolong larger, so as to the time delay in information interactive process is also than larger（More than 10ms is wanted typically）.But, as X2 connections are with more Layer checking, it is ensured that base station information interaction has very high accuracy.

In addition, physical layer connection can also be set up to carry out information exchange between base station, as physical layer connection pertains only to thing Reason layer operation, therefore using physical layer connection carry out information exchange time delay it is much smaller, can typically control within several ms. But, as physical layer connection does not have the process of high level, the accuracy of its information exchange it cannot be guaranteed that, common fault rate is higher than X2 connects.

To sum up, as the backhaul time delays between base station are larger, if the configuration information of a cell changes, or Minizone needs the schedule information of interactive user equipment, and long user equipment and the base station of being easily caused of interaction time delay is to same parameters Configuration understands differently the situation of cause, or causes schedule information notify in time, send so as to the signal for causing mistake or Receive.Typically there is following scene：

If the first, the enhancement mode Physical Downlink Control Channel of cooperation cell（enhanced Physical Downlink Control Channel, ePDCCH）Parameter changes, from the interaction between base station to by wireless heterogeneous networks（Radio Resource Control, RRC）Signal to user equipment, it may be necessary to longer time, cause user equipment cannot and The Shi Gengxin parameters.Such as, the signalling error of control information is sent using PDCCH or ePDCCH, user equipment may be caused Control channel flase drop；

If the 2, non-zero power of cooperation cell（Non-zero-power, NZP）Channel state information reference signals （Channel State Information-Reference Signal, CSI-RS）Updated etc. other information, if can not Interacted to notify to user equipment in time, then user equipment cannot carry out channel information according to the NZPCSI-RS after renewal Measurement, causes the cause that understands differently of transmitting terminal and receiving terminal；

If the 3, Physical Uplink Control Channel of user equipment（Physical Uplink Control Channel, PUCCH）Configuration information changes, if can not notify that, to each cooperation cell, each cooperation cell will be unable to correctly in time Receive A/N information and CSI；

If between the base station cooperation the 4, carried out by uplink receiving, the dynamic dispatching of interactive user equipment between base station is needed to believe Breath, if time delay is excessive, schedule information can not be interacted to cooperative base station in time；In addition, interactive user equipment feedback between base station During A/N information, it is also desirable to which, than relatively low time delay, otherwise user equipment cannot initiate necessary re-transmission in time；

5th, if up multi-flow PUSCH transmissions are not supported, then only serving BS just allows to send up Downlink Control Information（Downlink Control Information, DCI）To trigger CSI feedback aperiodic, in this case, The channel information of each cooperative base station can not be directly obtained by triggering CSI feedback aperiodic, so as to affect the tune of each cooperative base station Degree motility.

In sum, due to the backhaul between base station it cannot be guaranteed that being preferable, it is possible to there is propagation delay time and biography The restriction of defeated capacity etc., so as to cause can not to interact all information between each base station in time, so as to have impact on the transmission performance of system.
