Wherein, step S508 and step S510 are optional steps.And step S508 and S510 can be independently.
As shown in Figure 6, be that the flow chart that downlink resource distributes is carried out in the base station among Fig. 5 of the present invention.
Step S602, the base station is that broadcasting and the multicast service that many BS insert distributes continuous physical resource;
Step S604, the base station is all downlink business links by the terminal of this relay station control (except that broadcasting and multicast service that many BS insert) Resources allocation of first relay station.For further simplified receiver design, in a preferred embodiment of the invention, when carrying out resource allocation, the physical resource of the different business link of same terminal is continuous, has the physical resource of different terminals of identical relay station continuous in the grand diversity set.
Step S606, the base station is other all former downlink business link (except that broadcasting and multicast service that many BS insert) Resources allocation that are not assigned with the terminal of resource by the relay station of this base stations control.Distributing each time all no longer is broadcasting and the multicast service Resources allocation that many BS insert, also no longer for distributing the terminal distribution resource of resource.Up to the distribution of finishing all relay station resources.
Step S608, the base station is by the directly actuated terminal distribution ascending resource in base station.

BS1 at first distributes physical resource for the terminal SS1～SS3 that is subjected to RS1 control, because SS2 and SS3 will be controlled by RS2 will simultaneously, so the resource allocation of SS2 and SS3 is continuous; Then for being subjected to the terminal SS2～SS4 and the SS6 Resources allocation of RS2 control, because SS2 and SS3 distribute, so BS1 only is required to be SS4 and SS6 Resources allocation.RS1 receives the signaling from BS1, therefrom searches own terminal SS1, SS2 that controls and the downlink business address of SS3, and receives in the relevant position.RS2 receives the signaling from BS1 simultaneously, therefrom searches terminal SS2, the SS3 that oneself controls, the downlink business address of SS4, SS6, and receives in the relevant position.After receiving the corresponding downstream signal, relay station RS1 and RS2 prepare to transmit the corresponding downstream business to the terminal of being controlled separately.The base station begins to transmit constantly by signaling control RS1 and RS2, so that SS2, SS3 downlink business that the SS2 that RS1 sends, SS3 downlink business and RS2 send are synchronous.Like this, it is identical that the downlink business that RS1 and RS2 transmit arrives the time of SS2 and SS3, and SS2 can grand diversity merges the signal from RS1 and RS2, and SS3 can grand diversity merges the signal from RS1 and RS2.
Up, after the uplink service of terminal SS2 and SS3 arrives relay station RS1 and RS2 and is received by RS1 and RS2, base station BS 1 is adjusted the time that relay station begins to transmit uplink service, it is synchronous to make RS1 and RS2 begin moment of forwarded upstream, SS2 and the SS3 uplink service transmitted by RS1 and RS2 arrive the base station simultaneously, and the base station can realize that uplink macro diversity merges.
Next considers that the grand diversity between different base station merges.Terminal SS6 above considering in the topological structure can receive simultaneously by the signal of BS1 control through the RS2 forwarding, also can receive the signal of being transmitted through relay station RS3 by base station BS 2 controls.By the uplink and downlink resource allocation of adjustment base station BS 1, BS2 and beginning the forwarding moment of relay station RS2 and RS3, can realize that the grand diversity of SS6 merges.Its transmitted frame structure as shown in figure 10.
Consider a kind of business below again, the Multimedia Broadcast Multicast Service that promptly many sub-districts are inserted, a plurality of base stations of this business can be to the transmission broadcasting and the multicast service of a plurality of terminal synchronizes, and Multimedia Broadcast Multicast Service is inserted in many sub-districts of adopting method of the present invention to can be implemented in relay station.Be illustrated in fig. 11 shown below, multicast and broadcasting service that all terminals that receive through double bounce receive are synchronous, the multicast broadcasting service area territory roaming that can realize easily that grand diversity merges and insert in same many sub-districts.
In method provided by the present invention, the base station only is that each service link of each terminal distributes a physical resource, that is to say, the professional shared physical resource of the same terminal of different relay station controls is identical, resource utilization significantly improves, in addition, it is simple that it has realization, the advantage that signaling consumption is low;
The base station is by adjusting the moment of each relay station transmitting terminal business, make by the received signal of different relay station incoming terminals synchronous, to realize that grand diversity reception downstream signal of terminal or the grand diversity reception in base station come the upward signal of self terminal, can improve the quality of received signal.
Above disclosed only is preferred embodiment of the present invention, can not limit the present invention's interest field certainly with this, and therefore the equivalent variations of being done according to the present patent application claim still belongs to the scope that the present invention is contained.
