Description
Technical field
The present invention relates to wireless access technology, be specifically related to the data transmission method of wireless access system and base station, relay station and the wireless access system that uses the method.
Background technology
IEEE802.16j multi-hop relay task groups is the working group that IEEE set up in March, 2006, and its main purpose is the multi-hop expansion that defines IEEE802.16, in order to further increase the throughput and the coverage that enlarges system of system.This task groups strengthens the IEEE802.16e standard by use the multi-hop relay technology between base station (BS) and mobile radio station (MS), has defined and has supported the physical layer of multi-hop relay and system and the function of MAC layer.
But, do not support peer-to-peer communications in IEEE802.16j.Peer-to-peer communications is that the each party of communication has the traffic model that identical ability and each party can the initiating communication sessions.The reciprocity business of use multi-hop is normally transmitted between the user, and this business has such as flexibility, reliability, load balancing etc. plurality of advantages.
Yet, because the peer-to-peer communications business is difficult to be managed, controls, scheduling and charging, therefore seldom accepted by operator.Although there are some companies to propose to support that these suggestions are not accepted without the architecture of the reciprocity multi-hop transmission of BS in IEEE802.16j.This is because in these structures, this mobile radio station (MS) ← → relay station (RS) ← → multi-hop transmission of mobile radio station (MS) and without BS, neither set up and safeguard by BS, so BS can not manage it, controls, scheduling and charging.
For example, wireless Ad Hoc (Ad hoc) network is a kind of attractive alternative network topology for 4G network and IMT-Advanced (IMT-Advance) in the future.In this network topology, user terminal represents that other terminal receives and forwarding service, to form dynamic multi-hop Ad hoc network between the user.Yet due to the business between user transmission and without BS, therefore the key issue of this network topology is how operator controls this point-to-point service, so as to dispatch, management, charging etc.
In existing hop relay network, owing to not supporting peer-to-peer communications, all up links and downlink traffic must be passed through BS, have formed hub-and-spoke network topology.Because flow aggregate makes the link that leads to BS usually have high capacity and easily becomes bottleneck.In addition, multi-hop relay has also increased some extra signal transmission delays.This extra delay may comprise processing delay and the dispatch delay in RS.This problem is very serious in the control signal exchange.For example, the MS bandwidth request may need could arrive BS through multi-hop relay through the longer time.In addition, because each RS has covered less zone, so the movement in the residential quarter is more flexible, and current handover scheme switches and designs for minizone (inter-cell), and is not suitable for (intra-cell) switching in the residential quarter.Therefore also need to be for the more effective handover scheme of frequency shifts in the residential quarter.
In order to address the above problem, in IEEE802.16j, accepted the IEEE C802.16-07/023r3 motion that Alcatel Lucent proposes " Frame Structure forTransparent Relay Mode (frame structure that is used for the transparent relay pattern) ", and it has been included in IEEE 802.16j D2 standard.In this transparent relay pattern, the MS relevant to RS is arranged in the coverage of BS, then directly arrives MS from lead code and MAP (resource distribution) signaling of BS in RS, is also not transmission preamble code and MAP of RS.All MS in residential quarter and RS keep synchronizeing with BS by the lead code of BS, and (DL-MAP is the MAC layer-management message that defines the downlink burst zero-time to obtain DL MAP and UL MAP from BS, UL-MAP is the MAC layer-management message that defines the uplink burst zero-time), distribute according to the resource in MAP the data flow is carried out relaying.
Transmission provides time delay still less to this transparent relay pattern for downlink control signal, and has simplified the design of RS, has reduced the complexity of RS, also is conducive in addition switching within cell.Yet due to backward compatible demand, this design still has some limitation.Particularly, in this pattern, control signal only is applied to down link with separating of data, and the control signal of all up links and data still must experience the extra delay that is caused by multi-hop.This multihop network remains star topology, so all flows still assemble at the BS place, thereby may cause the flow bottleneck.Therefore, this pattern still can not be supported peer-to-peer communications flexibly.
In sum, in existing cellular network or hop relay network, because all data traffics must be assembled the shortcoming that causes producing flow bottleneck and propagation delay time at the BS place.Although peer-to-peer communications can address this problem effectively, if peer-to-peer communications is introduced existing cellular network or hop relay network, can make BS can not control MS or can not obtain control information from MS.And flow bottleneck and propagation delay time problem that above-mentioned transparent relay pattern still exists the data convergence of up link to cause at the BS place also still can not be supported peer-to-peer communications flexibly.
