The Part I 210 of DL subframe 200 comprises BS preamble channel 211, control channel 213 and Traffic Channel 215, for from BS by the transmission of direct link to RS and MS.

The Part II 220 of DL subframe 200 comprises preamble channel 221, control channel 223 and Traffic Channel 225, for from BS by the transmission of repeated link to MS.

The Part I 240 of UL subframe 230 is for from RS and MS connected by direct link to BS control information transmission and business datum.The Part II 250 of UL subframe 230 is for sending control information and business datum from the MS connected by repeated link to RS.

As mentioned above, in order to support trunking plan, wireless communication system uses frame structure as shown in Figure 2 to carry out executive communication.But double bounce wireless communication system only supported by the frame structure in Fig. 2, because this frame structure is not for the part of RS-RS communication.Therefore, the frame structure of wireless communication system needs for supporting multi-hop relay business of trunking plan is used.

The invention provides a kind of scheme for frame information to be sent at multihop relay wireless communication system downstream RS from upstream node.Here, upstream node represents BS or upstream RS.

Following description is that background is carried out with time division duplex OFDM (TDD-OFDMA) wireless communication system, but the present invention is not limited to this.Therefore, should be expressly understood, the present invention can be applicable to other multi-address radio communication system arbitrarily.

In order to support multi-hop relay business, wireless communication system uses frame structure executive communication as shown in Figure 3.But should be expressly understood, the present invention is applicable to other frame structure arbitrarily.

Fig. 3 shows the frame structure according to multihop relay wireless communication system of the present invention.

With reference to Fig. 3, this frame comprises DL subframe 300 and UL subframe 310.

When this wireless communication system uses double bounce, DL/UL subframe 300/310 is divided into Part I 301/311 and Part II 303/313.Part IV 307/317 is there is between Part I 301/311 and Part II 303/313.But, when wireless communication system uses double bounce, there is not Part IV 307/317.Therefore, Part I 301/311 and Part II 303/313 can expand to Part IV 307/317.In Part I 301/311, BS with RS communicates with the MS in its overlay area.In Part II 303/313, BS and RS communicates.

When wireless communication system supports real time service, RS must carry out repeating signal, to reduce transmission delay with a frame.Therefore, DL/UL subframe 300/310 is divided into Part I 301/311, Part II 303/313 and Part III 305/315.In Part I 301/311 and Part III 305/315, BS with RS communicates with the MS in its overlay area.In Part II 303/313, BS and RS communicates.In other words, on the uplink, RS utilizes Part II 303 to receive data from BS.Thereafter, utilize Part III 305, RS by utilize Part II 303 to receive from BS data relay to the MS in its overlay area.

As mentioned above, this subframe is divided into three parts by the size of two parts that can be divided in the subframe of two parts by adjustment.Alternatively, by adding Part III in the subframe being divided into two parts, this subframe can be divided into three parts.

When wireless communication system uses three or more jumping, this frame must comprise such as, part for communicate between RS (that is, the communication between RS, the communication between upstream RS and downstream RS).Therefore, before or after being positioned at Part II 303/313 for the part communicated between RS.
