When carrying out resource distribution by relay station 1 and the 3 pairs of relay stations 2 and 4, configuration messages produces and sends to relay station 2 and 4 by relay station 1 and 3.Relay station 2 and 4 after receiving this configuration messages to self carrying out corresponding configuration and replying an ACK message and confirm for relay station 1 and 3.Relay station 1 and 3 starts timer after sending configuration messages, if do not receive the ACK message that relay station 2 and 4 is sent before timer is expired, should resend this configuration messages.
Described above is resource allocation process, and by means of the foregoing description, the resource that relay station can use base station assigns and terminal are communicated by letter with the lower floor relay station.Further, for the service traffics that adapt between relay station-terminal, the relay station-lower floor's relay station change, the base station can in time be adjusted into the resource that relay station distributes.Following embodiment has just described the correlated process that resource allocation is adjusted.
In the multi-hop relay network, data traffic between relay station-terminal, the relay station-lower floor's relay station can be in time or place (as mobile-relay station) bigger change takes place, the relay station that for example is positioned at office block can significantly reduce traffic carrying capacity evening, and the relay station that is positioned at the residential block then can significantly improve traffic carrying capacity at night.In order in time to adjust the resource that relay station uses between relay station-terminal, relay station-lower floor's relay station according to traffic carrying capacity, the present invention's method that different network configurations and relay station ability are adjusted respectively of giving chapter and verse.
Method embodiment four
According to the embodiment of the invention, a kind of resource adjusting method is provided, this method is applied to the double bounce junction network; In the double bounce junction network, only there is the access link of relay station-terminal in relay station.Resource allocation adjustment between relay station-terminal can have two kinds of methods.
Method one: the base station is initiatively adjusted
The base station can judge whether that resource allocation is adjusted to relay station according to the service traffics and the channel quality of link between base station-relay station.Under the situation that needs are adjusted, the base station is initiatively adjusted the resource allocation of relay station, and sends resource allocation adjustment message to relay station, notifies its new resource allocation.
The base station send resource allocation adjust message to relay station after, relay station provides respective feedback.Preferably, the base station sends resource allocation adjust message after, can start timer, and when also not receiving respective feedback when timer is expired, the base station will send resource allocation once more and adjust message.
Method two: relay station sends to the base station and adjusts application
At this moment, relay station will send resource adjustment request to the base station, and the base station receives after this application, sends resource allocation and adjusts message to relay station, and relay station provides respective feedback again.
Preferably, if relay station does not receive at the appointed time that after proposing to adjust application respective feedback will send resource once more and adjust request.This can realize by timer equally.Similarly, the base station is after sending resource allocation adjustment message, if do not receive respective feedback at the appointed time, the base station will send resource allocation once more and adjust message.
Method embodiment five
In multi-hop relay network greater than double bounce, the relay station place exists access link between relay station-terminal and the repeated link between relay station-lower floor's relay station, the service traffics of link are made up of relay station-terminal access link and relay station-lower floor's two-part service traffics of relay station relays link between base station-relay station, therefore, base station or upper strata relay station can't be according to the service traffics estimation relay station-terminal of link between base station-relay station or the upper strata relay station-relay station, the service traffics between relay station-lower floor's relay station.At the multi-hop relay network greater than double bounce, the present invention proposes the method for adjustment that link circuit resource distributes between the relay station-terminal, relay station-lower floor's relay station under following two kinds of situations.
Situation one: relay station itself has the ability that resource is adjusted
(1) for the terminal relay station in the multi-hop relay network, its resource of using between relay station-terminal can be adjusted by the access relay of terminal relay station; Insert relay station and send resource allocation adjustment message to terminal relay station, terminal relay station provides respective feedback.
Preferably, after the access relay station sends resource allocation adjustment message,, will send resource allocation once more and adjust message if do not receive respective feedback at the appointed time.This can realize by timer.
(2) for the intermediate repeater station outside the terminal relay station, its resource adjustment of using between relay station-terminal, relay station-lower floor's relay station should be undertaken by the base station.
Particularly, relay station sends resource adjustment application to the base station, and the base station receives after the application, sends resource allocation and adjusts message to all the other intermediate repeater stations, and all the other intermediate repeater stations provide respective feedback again.
Preferably, intermediate repeater station if do not receive respective feedback at the appointed time, will send resource adjustment request after proposing to adjust application once more.Similarly, after the base station sends resource allocation adjustment message, if do not receive respective feedback at the appointed time, the base station will send resource allocation once more and adjust message.
Situation two: relay station itself does not have the ability of resource allocation
In this case, the resource of using between all relay station-terminals, the relay station-lower floor's relay station is all distributed by the base station.Particularly, the resource adjustment of using between all relay station-terminals, the relay station-lower floor's relay station should send resource adjustment application to the base station by relay station, and corresponding resource allocation adjustment is carried out after receiving application in the base station.
Particularly, the base station sends resource allocation and adjusts message to relay station after receiving application, and relay station provides respective feedback again.Preferably, after relay station proposes to adjust application, if do not receive respective feedback at the appointed time, relay station will send resource adjustment request once more.Similarly, incite somebody to action if receive respective feedback at the appointed time after sending resource allocation adjustment message the base station, and the base station sends resource allocation once more and adjusts message.
Need to prove that resource adjustment request above-mentioned is for increasing resource request or a resource shrinkage request, correspondingly, resource allocation is adjusted message for increasing message related to resources or reducing message related to resources.The available resources of distributing between relay station-terminal above-mentioned, the relay station-lower floor's relay station can be the Resource Block of time-domain resource, frequency domain resource and time-frequency bidimensional.
Referring again to Fig. 1, for the situation that only comprises the relay station that directly links to each other with the base station in the wireless multi-hop relay network, for example, relay station 1 and 3, so relay station 1 and 3 and terminal between service traffics when bigger variation takes place, on the one hand can by the base station by supervision relay station 1 and 3 and between self the data traffic on the link change infer relay station 1 and 3 and terminal between data traffic change, and then to relay station 1 and 3 and relay station between resource allocation adjust; On the other hand, can be changed to send to the base station according to the service traffics between own and the terminal by relay station 1 and 3 and adjust application, the base station adjusts accordingly according to this application, and will adjust the result and send to relay station, after relay station is received adjustment information, should reply ACK and confirm.
As mentioned above,, the presence of intercell interference of relay station/base station on repeated link be can avoid, simultaneously, the bandwidth deficiency or the wasting phenomenon that cause when relay station traffic carrying capacity on repeated link takes place by bigger the variation solved by means of the present invention.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
