Technical field
The present invention relates to based on wireless relay network, relate in particular to moving eventually for relay station jurisdiction in wireless relay networkThe method and apparatus of end scheduling resource.
Background technology
In IEEE802.16j, define the relaying of two types: transparent relay and opaque relaying.
Transparent relay can only be used for improving the handling capacity of cell edge mobile terminal, increases the capacity of system, and it does not expandThe coverage of large community. Therefore,, in wireless relay network, the mobile terminal of transparent relay jurisdiction must be positioned at covering of base stationWithin the scope of lid. The mobile terminal of transparent relay jurisdiction directly obtains control information from base station, wherein, and before this control information comprisesLead symbol, the information such as mapping table.
Conventionally, adopt centralized resources scheduling mechanism in transparent relay network, system resource is by base station United Dispatching.
Opaque relaying can either increase the capacity of system, can expand again the coverage of community. Therefore, in wirelessContinue in network, the mobile terminal of opaque relaying jurisdiction is without the coverage that is positioned at base station. Opaque relaying is relaying number not onlyIt is believed that breath, and can directly send control information.
In opaque junction network, not only base station can be dispatched resource, and opaque relaying also can be rightResource is carried out certain management, by the coordination of base station and relay station, resource dynamic is distributed to corresponding mobile terminal, to subtractThe burden of light base station, optimized allocation of resources, Hoisting System performance.
In opaque junction network, both can adopt centralized resources scheduling mechanism, also can adopt distributed resourceScheduling mechanism. In the time adopting distributed mechanism, the mobile terminal in a coverage first disappears their resource allocation requestBreath sends to the relay station into its service, and all resource allocation request message of receiving are processed rear transmission by relay station subsequentlyGive base station, notify this relay station after certain resource has been granted in base station, relay station can be distributed to resource to carry according to dispatching algorithmGo out the mobile terminal of resource allocation request. Distributed scheduling is compared with centralized scheduling, because relay station can be fast and accuratelyObtain the information such as resource, channel condition in its overlay area, can shorten the time delay of resource request, more effectively utilizedRadio Resource.
In IEEE802.16m, adopt more senior air interface, therefore, multi-hop relay is very important needAsk. 802.16m work group has considered two kinds of possible multi-hop relay solutions at present. A solution is 802.16mRelaying is only supported opaque relaying; Another kind of scheme is that 802.16m relaying is supported transparent relay and opaque relaying simultaneously. AobviousSo, no matter take above-mentioned which kind of solution, 802.16m relaying must be supported opaque relaying.
Fig. 1 shows the typical application scenarios according to the opaque relaying of prior art. For convenience of description, hereinafter will" Radio Resource that base station is shared also sets it as relay station and the mobile terminal that its resource of arranging is its jurisdiction and dividesThe part resource of joining " referred to as " base station resource "; By " Radio Resource that relay station is shared also sets it as that it arrangesResource is the part resource that the network equipment of its jurisdiction distributes " referred to as " relay resource ".

Same, in " base station 30 frames " corresponding in " relay station 20 frames " " mobile terminal 10 →Relay station 20 " part space also should be idle condition.
In this detailed description of the invention, base station 30 is directly sent to mobile terminal 10 by first resource relevant information, due toWhen first resource relevant information is sent to mobile terminal 10 by base station 30, relay station 20 is also being 11 points of mobile terminalsThat joins is sent to mobile terminal 11 for this relay station 20 and the resource related information of the transfer resource of mobile terminal 11, therefore,Relay station 20 can not be received the first resource relevant information that base station 30 sends. And due to relay station 20 need to mobile terminal 10Communicate, therefore, relay station 20 equally also must be known the resource situation that base station 30 is distributed for mobile terminal 10.
For addressing the above problem, at least can adopt following two kinds of modes:
1), with reference to Fig. 5, previous frame and the present frame of the base station 30 shown in Fig. 5 comprise " mapping ", " relaying mapping ", " underLine link access region ", " downlink relay region ", " up-link access region ", " up-link access region ". AboutParticular content in each region, can be with reference to the frame structure in Fig. 4.
Base station 30 will be sent to the first resource relevant information of mobile terminal 10 in present frame, and base station 30 is for eventually mobileThe resource information that end 10 distributes, " the relaying mapping " of putting into the previous frame of base station 30 after copying, like this, relay station 20 just canFrom " relaying mapping " information of the previous frame of base station 30, obtain the resource letter distributing for mobile terminal base station 30 in present frameBreath.
2) in " the downlink relay region " of the previous frame of base station 30, send a particular message, in this message, compriseThe resource information that base station 30 is distributed for mobile terminal 10 in present frame.
Finally, the Radio Resource directly being distributed by base station 30 that mobile terminal 10 utilizes first resource related news instructions withRelay station 20 communicates.
In the embodiment of a variation, in wireless multi-hop relay network as shown in Figure 6, the coverage of relay station 20Within the whole coverage that is positioned at base station 30. Mobile terminal 12 is directly base station 30 jurisdictions, and mobile terminal 10 is relay station 20Jurisdiction.
When base station 30 determines by after being mobile terminal 10 Resources allocation its own base station resource of arranging from it, Fig. 6The base station resource that in shown wireless multi-hop relay network, all mobile terminals are all directly arranged from it by base station 30, beIts Resources allocation, relay station 20 no longer participates in the distribution of resource. Thereby make relay station 20 without sending lead code, frame controlHead, resource related information, for example, and uplink map and downlink map, to mobile terminal 10, therefore, as shown in Figure 7Frame structure, the frame head part in " relay station 20 frames " is " free time ". In Fig. 7, the each several part content of frame structure can be referring to Fig. 4In description.
Equally, in the present embodiment, because relay station 20 need to communicate with mobile terminal 10, therefore, relay station 20Must know the resource situation that base station 30 is distributed for mobile terminal 10. Although, in frame structure as shown in Figure 7, " relay station 20Frame " in frame head part be " free time ", if but relay station 20 utilizes this idling-resource to receive base station 30 for mobile terminal 10The resource related information distributing, afterwards, relay station 20 must switch and enter sending mode from receiving mode at once, and thisSwitching between pattern will bring very large time delay.
Therefore, for fear of receiving mode to sending mode transfer process in the generation of time delay, relay station 20 obtains base station30 resource situation of distributing for mobile terminal 10 still need to adopt above-mentioned two kinds of modes mentioning, for simplicity's sake, do not go to live in the household of one's in-laws on getting married at thisState.
Due in the frame structure of opaque relaying, the position in relaying region and size can change. Therefore, as Fig. 8 instituteShow, can, by adjusting the order in relaying region and access region, relay station 20 and mobile terminal 10 can be received simultaneouslyThe resource related information distributing for mobile terminal 10 to this base station 30 sending from base station 30.
