Description
Technical field
The present invention relates to relaying technique, the data transmission method in particularly a kind of wireless relay system, a kind of wireless relay system and a kind of base station.
Background technology
Relaying is an important technology that possibly use in senior international mobile communication (IMT-Advanced, the International MobileTelecommunication-Advanced) system, is mainly used in the increase system and covers or the increase capacity.After in network, introducing via node (RS, Relay Station), the Radio Link of Access Network side will be divided into two types, that is: access link (Access-Link) and repeated link (Relay-Link).Wherein, access link is meant the Radio Link that starts from or end in portable terminal (MS, Mobile Station); Repeated link is meant Radio Link or the Radio Link between RS and the RS between base station (BS, Base Station) and the RS.Access link and existing system, similar like MS and the link between the BS in the long evolving system (LTE, Long Term Evolution), repeated link then is not relate in the existing cell mobile communication systems.In addition, be called access relaying (Access Relay), be not called intermediate relay (Intermediate Relay) with the RS that MS directly links to each other with the RS that MS directly links to each other.
Existing wireless relay system generally all adopts the tree topology structure, promptly by the resource of the RS in BS unified management BS and the BS administrative area, and is responsible for realizing the switching between different districts/sector in the BS/RS.According to different apart from the jumping figure of BS, can with RS be divided into the 1st grade of RS, the 2nd grade of RS ..., and n level R.Each RS has a plurality of RS of subordinate, but RS only links to each other with a higher level RS, and RS at the same level is continuous, therefore, has only a paths from a RS to another RS.Higher level RS is called the Control Node of the RS of subordinate again, is responsible for accomplishing resource management and the distribution of all RS of subordinate in its coverage.Control Node meeting fixed time broadcast is to the control command of the RS of subordinate, and like this, the RS of subordinate just can the correct fetched in the downlink business frame go out to send to the data of oneself, and the data of corresponding position transmission oneself in the uplink service frame.In wireless relay system, BS and each RS can the same running time-frequency resources of orthogonal multiplex in the interference range that allows, also can nonopiate multiplexing same running time-frequency resource.
In addition; Existing micro-wave access to global intercommunication (WiMAX; Worldwide Interoperability forMicrowave Access) in the system a kind of service quality (QoS is provided; Quality of Service) mechanism, soon data packets for transmission and the Business Stream by connection identifier (CID (CID, Connection Identifier) sign associate between BS and MS.Article one, Business Stream is exactly the one-way data bag stream that specific QoS is provided, and professional type and qos parameter (comprising information such as speed, time delay and the grade of service) all are implicitly included among the CID.Qos parameter according to Business Stream in communication process is distinguished priority scheduling, and corresponding QoS Service Properties is provided.Control Node makes controlled node know running time-frequency resource position and transformat that this Business Stream takies to the CID transmitting control commands.
After introducing relaying, if the QoS of different service streams is identical, so, the transformat of different business stream on repeated link that is to say that with identical Control Node is to different service streams, with sending identical control command.In order to reduce the control signaling consumption of repeated link, simplify the processing of middle RS, the notion of a kind of " tunnel connection " has been proposed in the WiMAX system.It is the two-way connection between BS and the access RS that the tunnel connects, and can carry the data through many Business Streams in this tunnel.The tunnel connects and to be connected similarly with common, all distributes a CID, is used to identify the qos parameter of this tunnel connection; Specifically, the qos parameter that connects of tunnel is the set of the qos parameter of all Business Streams of carrying of this tunnel.In practical application, behind the Business Stream of having created a BS to MS, by the BS decision which bar tunnel this Business Stream is mapped to and connects, and revise the qos parameter that corresponding tunnel connects, so that it comprises the qos parameter of this Business Stream.The Business Stream qos parameter is invisible for the middle RS of Business Stream; Middle RS can only be with reference to the qos parameter of tunnel connection; For being mapped to the different business stream that same tunnel connects, transmit according to the principle of " FIFO ", and; Can be in same Resource Block multiplexing transmission, and use identical transformat.
But above-mentioned being mapped between the different business stream that same tunnel connects must meet some requirements, and promptly transmission path is identical and QoS is identical, that is to say to have only the identical Business Stream of the RS of access just can be mapped to same tunnel and connect.So, on repeated link, the Business Stream that QoS is identical just may be mapped to different tunnels and connect owing to transmission path is different, thereby causes and can't more effectively carry out Unified Treatment to the identical Business Stream of QoS, to reduce the control signaling consumption.
Illustrate: Fig. 1 is the structural representation of existing a kind of wireless relay system.As shown in Figure 1, Tunnel00 and Tunnel# 1 are the tunnel between BS and the RS2, are used to carry the business of two kinds of different QoS of MS0 and MS1; Tunnel# 2 is the tunnel between BS and the RS3, is used to carry the business of a kind of QoS of MS2 and MS3.That is to say that different according to difference that inserts RS and QoS co-exist in 3 tunnels between BS and RS1.Like this; Even Tunnel# 2 is identical with the QoS that Tunnel# 1 goes up loaded service stream; BS and RS1 also can only handle respectively Tunnel# 2 and Tunnel# 1, reduce the control signaling consumption of BS to the repeated link of RS 1 and can not make full use of the identical characteristics of different business stream QoS.

Embodiment
To the problem that exists in the prior art; The present invention proposes the data transmission scheme in a kind of wireless relay system; That is: when setting up new Business Stream; BS receives the professional request of setting up, and according to the transmission path of this Business Stream, the qos parameter of this Business Stream is added in the qos parameter of the QoS set that in the transmission path each jumps repeated link; Said QoS set is meant the QoS set identical with the QoS of this Business Stream, and the numbering and the qos parameter of the QoS set of having added this Business Stream qos parameter are notified to each Control Node on the transmission path; When carrying out transfer of data, each Control Node is dispatched self QoS collection, and control command is sent to sending node; Sending node is according to the control command that receives, the data transfer mode of the confirming self QoS collection data transfer of going forward side by side; Receiving node receives the data from sending node, and therefrom takes out the packet of different business stream, is distributed in the corresponding buffer memory.
Thus it is clear that, in the scheme according to the invention, on each bar repeated link; Respectively the identical Business Stream of QoS is integrated, formed the QoS set of different QoS Business Stream, and no longer be confined to have only the Business Stream of identical access RS just can be mapped in the connection of same tunnel as prior art; Thereby it is identical to have made full use of different business stream QoS; The characteristics that transformat is identical make Control Node be directed against QoS set transmitting control commands, have reduced the control signaling consumption.
Fig. 2 carries out the sketch map after Business Stream is integrated for adopting scheme according to the invention to wireless relay system shown in Figure 1.As shown in Figure 2; Because the Tunnel# 2 among former Fig. 1 is identical with the QoS that Tunnel# 1 goes up loaded service stream, so, with Tunnel# 2 and Tunnel# 1 upward loaded service flow and integrate; And on repeated link, introduce the notion that Business Stream QoS gathers, obtain the Group# 1 shown in Fig. 2.Like this, to the repeated link of RS1,, can be divided into two QoS set, Group# 0 and Group# 1 at BS according to the difference of QoS; To the repeated link of RS2,, gather Group# 0 and Group# 1 at RS1 so be divided into two QoS equally because it is professional to carry two kinds of different QoS; To the repeated link of RS3,, only need a QoS set Group# 2 at RS1 owing to only carry a kind of QoS business.Like this,, be divided into into two QoS set,, be divided into into 3 QoS set for the second jumping repeated link for the first jumping repeated link.
Send because Control Node will be carried out resource allocation and authorization message to subordinate's link, therefore, each numbering of jumping each QoS set of Control Node subordinate can not repeat, and is separate but respectively jump the numbering that the QoS between the Control Node gathers.With Fig. 2 is example, BS to the repeated link of RS1 and RS1 all have the QoS set that is numbered Group# 0 and Group# 1 to the repeated link of RS2, but because two repeated links belong to different Control Node of jumping, so can not have problems.Perhaps, BS also can directly number all QoS set unifications of each Control Node subordinate.Fig. 3 can find out on the basis of Fig. 2 each QoS being gathered the sketch map after unification is numbered, in Fig. 3, with unified Group# 0, Group# 1, Group# 2, Group# 3 and the Group# 4 of being numbered of the set of the QoS on three repeated links.
Each QoS set has the qos parameter of oneself, comprises the qos parameter of all included Business Streams of this QoS set.When each new Business Stream was set up, BS was mapped to this Business Stream in the different QoS set on every jumping repeated link according to the transmission path and the qos requirement of this Business Stream.The traffic data that belongs to same QoS set wraps among the RS can uniform dispatching, unifiedly carries out resource authorization, in same Resource Block, carries out multiplexingly, uses identical transformat to transmit, thereby has simplified the processing of RS.In addition, RS can carry out differentiated treatment to different business according to the difference of QoS, such as carrying out differentiated treatment for real time business and non-real-time service etc., has guaranteed the propagation delay time and the bandwidth demand of different pieces of information, has guaranteed wireless resource utility efficiency simultaneously.
For making the object of the invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is done to specify further.
Fig. 4 is the flow chart of the data transmission method embodiment in the wireless relay system of the present invention.As shown in Figure 4, may further comprise the steps:
Step 401: when setting up new Business Stream, BS receives the professional request of setting up, and according to the transmission path of this Business Stream, the qos parameter of this Business Stream is added in the qos parameter of the QoS set that in the transmission path each jumps repeated link.
When setting up new Business Stream between BS and the MS; At first, BS is mapped to this Business Stream in the QoS set of each the jumping repeated link in the transmission path according to the transmission path of Business Stream; And revise the qos parameter that QoS gathers, so that it comprises the qos parameter of this Business Stream.That is: according to the transmission path of Business Stream; Confirm all repeated links that Business Stream need pass through; And confirm that each jumps the numbering of the set of the QoS under this Business Stream in repeated link, the qos parameter of this Business Stream is added in the qos parameter of each QoS set of determining.
Illustrate:
Fig. 5 is the qos parameter addition manner sketch map among the inventive method embodiment.As shown in Figure 5, suppose that Business Stream k will join among the QoS set Group# 0, and comprised two Business Streams among the Group# 0 originally, Business Stream m and Business Stream n.In the qos parameter of Group# 0 correspondence, each parameter all is certain function of Business Stream m and Business Stream n relevant parameter; After Business Stream k joins among the Group# 0, each qos parameter in the Group# 0 parameter all will be three Business Stream m, n, certain function of the relevant parameter of k.
Step 402:BS notifies the numbering and the qos parameter of the QoS set of having added this Business Stream qos parameter to each Control Node on the transmission path.
Each Control Node is according to the numbering of the QoS set that receives, and knows that self which QoS set is relevant with this Business Stream, and the qos parameter in according to the qos parameter that receives self QoS being gathered upgrades.
Further, BS also can notify the qos parameter information of this Business Stream to each Control Node on the transmission path in the lump, and concrete purposes will be in follow-up introduction.
Step 403: when carrying out transfer of data, each Control Node is dispatched self QoS collection, and control command is sent to sending node.
In this step, Control Node is dispatched between self pairing different QoS set, and the foundation of dispatching algorithm can be the overall buffer status of Business Stream in current channel quality, each QoS set and the qos parameter of each QoS set etc.; The running time-frequency resource position that each QoS set in the dispatching cycle of determining is taken and the information such as transformat of use send to sending node through control command.Concrete send mode can be that ID is a sign with the QoS set, and control command is sent to sending node.
Because when Control Node is dispatched to different QoS set; Multi-business flow is shared same Resource Block, carries out data multiplex in the Resource Block, uses identical transformat; Therefore only need unify to send once to the control command of the Business Stream in each QoS set in a control cycle; Wherein, the ID territory in the Resource Block authorization message is set to Group ID, is the shared resource of multi-business flow with this Resource Block of indication receiving node.Suppose to comprise altogether in the control range of certain Control Node 3 QoS set, be respectively Group# 0, Group# 1 and Group# 2, then the each control command of sending of this Control Node is with as shown in Figure 6.
Step 404: sending node is according to the control command that receives, the data transfer mode of the confirming self QoS collection data transfer of going forward side by side.
In this step; Sending node is according to receiving Resource Block authorization message and transport format information; Confirm running time-frequency resource position and employed transformat and transmission block size etc. that self QoS collection is shared; And form sending data block, the packet that is about to belong to each Business Stream of identical QoS set cascades up and utilizes same Resource Block to transmit.As shown in Figure 7, Fig. 7 is the traffic data bag cascade system sketch map among the inventive method embodiment.In practical application, sending node can be confirmed the resource occupation amount of each Business Stream in the Resource Block according to the principle of FIFO, promptly according to the arrival order of traffic data bag, arranges the resource allocation conditions in the Resource Block; Perhaps; Also can be according to the qos parameter (being the qos parameter that is received from BS in the step 402) of each Business Stream; Stock number to each Business Stream in the Resource Block takies is distributed, and promptly arranges the resource allocation conditions in the Resource Block according to certain dispatching algorithm, thereby has increased the flexibility of RS to resource allocation.
In addition, need to prove that for downlink transfer, the Resource Block authorization message is exactly that sending node self produces in fact, that is to say that in this case, Control Node and sending node are same RS; And for uplink, then be by Control Node the Resource Block authorization message that produces to be notified to sending node.
Step 405: receiving node receives the data from sending node, and therefrom takes out the packet of different business stream, is distributed in the corresponding buffer memory.
Receiving node is according to shared running time-frequency resource position and the information such as transmission block size and transformat of each QoS set; Receive the corresponding data block of each QoS set in the corresponding way in corresponding position; And the packet that will belong to different business stream extracts, and is distributed in the buffer memory of next jumping.This buffer memory can be meant the buffer memory to the different QoS set of next jumping, also can be meant the buffer memory of independent Business Stream.As shown in Figure 8, Fig. 8 is the traffic data bag cache way sketch map among the inventive method embodiment.Receiving node receives 3 Business Stream m, and n after the data block that k shares, therefrom extracts the packet of each Business Stream, and next jumping that is distributed to each Business Stream is sent in the buffer memory.
