In the 802.16j system, when scheduling mode is distributed scheduling,, just need to send CDMA (Code Division Multiple Access, code division multiple access) sign indicating number bandwidth on demand if there is not available bandwidth to send bandwidth request header or message.As shown in Figure 1, be prior art CDMA sign indicating number bandwidth request flow chart, MS sends bandwidth request code by RS to MR-BS (Multihop relay base station, multi-hop relay base station), and MR-BS is that MS distributes corresponding bandwidth.
Prior art in repeated link, based on CDMA sign indicating number bandwidth request procedure and the bandwidth request ranging code method of salary distribution of competition with identical in access link.Like this, when receiving the CDMA bandwidth request code, can there be two kinds of bandwidth request in the RS for MS inserts, first kind be downstream site only need be between downstream site and this node the bandwidth in the link; Second kind is the bandwidth that downstream site need be from downstream site to MR-BS whole piece link.
For first kind of bandwidth request, inserting RS only needs link assignment bandwidth between the downstream site is got final product, and need not to report MR-BS to carry out allocated bandwidth.For second kind of bandwidth request, insert RS and need in repeated link, continue upwards level node bandwidth on demand, as the CDMA sign indicating number bandwidth request flow process based on competition of existing distributed scheduling among the 802.16j.As Fig. 1, report MR-BS to carry out allocated bandwidth in the prior art and to above-mentioned two kinds of bandwidth request unifications, like this, when subordinate's node only needs self to arrive the bandwidth that inserts between the RS, can cause and insert the waste that has distributed bandwidth between RS and the MR-BS.
Summary of the invention

Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail:
The bandwidth request method flow diagram of the embodiment of the invention one as shown in Figure 2 may further comprise the steps:
Step S201, RNG RSP (Ranging Response when MR-BS passes through initial ranging, ranging response) message distributes bandwidth request ranging code (hereinafter to RS, as not making specified otherwise, mentioning that when RS distributes bandwidth request ranging code the content of this assignment messages must be known by the higher level RS of this RS simultaneously.)。RS just can distinguish single-hop bandwidth request code word and multi-hop bandwidth request code word after receiving the bandwidth request ranging code that MR-BS distributes, for example MR-BS can issue RS with single-hop bandwidth request code word and multi-hop bandwidth request code word; Perhaps MR-BS only issues RS with multi-hop bandwidth request code word or multi-hop bandwidth request code word scope, and other code word is exactly single-hop bandwidth request code word for RS; Perhaps MR-BS only issues RS with single-hop bandwidth request code word or single-hop bandwidth request code word scope, and other code word is exactly multi-hop bandwidth request code word for RS; As a preferred embodiment, in order to reduce the signaling burden, the single-hop bandwidth request code word that MR-BS only will distribute to this RS is issued the higher level RS of this RS and this RS, like this, when RS received the code word of downstream site transmission, what just can judge the downstream site transmission was single-hop bandwidth request code word or multi-hop bandwidth request code word.Wherein, single-hop bandwidth request code word only ask and superior node between the bandwidth of up link; Multi-hop bandwidth request code word not only ask and superior node between the bandwidth of up link, the multi-hop link upstream bandwidth between request and the MR-BS also.Need to prove that the above-mentioned RNG_RSP message of passing through of the embodiment of the invention only is more excellent execution mode to RS distribution bandwidth request ranging code, the scope of the above-mentioned bandwidth request ranging code of other message informings RS that can send by MR-BS also, or directly on RS, dispose above-mentioned bandwidth request ranging code (single-hop bandwidth request code word and/or multi-hop bandwidth request code word), therefore can make RS can distinguish single-hop bandwidth request code word and multi-hop bandwidth request code word as can be seen in several ways.Thereby all should be embodiment of the invention protection range for any similar variation of this step and contain.
As a preferred embodiment,, single-hop bandwidth request code word is distributed to each RS by expansion to RNG_RSP message.Wherein the CDMA code word can be divided into RS and shared code word and the independent code word of using of RS of MS.Therefore can in the code word that RS uses separately, define corresponding single-hop bandwidth request code word, the corresponding one or more single-hop bandwidth request code words of each RS, and the single-hop bandwidth request code word of different RS correspondences is different.The MR-BS superior node that only needs single-hop bandwidth request code word is sent to corresponding RS and this RS gets final product like this, is single-hop bandwidth request code word and need not to notify which CDMA code word of each RS, and which CDMA code word is a multi-hop bandwidth request code word.After receiving the bandwidth request ranging code of downstream site as a RS, judge whether that the single-hop bandwidth request code word of certain downstream site of this RS of distributing with MR-BS is identical, if identical then what illustrate that downstream site sends is single-hop bandwidth request code word; If it is inequality then what illustrate that downstream site sends is multi-hop bandwidth request code word.
The embodiment of the invention can be by the TLV (Type-Length-Value in the RNG_RSP message, type-length-value, a kind of form) is defined as the single-hop bandwidth request code word that RS distributes, the single-hop bandwidth request code word that each RS is corresponding different, value as shown in the table, that each RS is corresponding different.Certainly, also can adopt other forms to inform the single-hop bandwidth request code word that RS distributes in RNG_RSP message, only be one of them embodiment herein.MR-BS sends the RNG_RSP message of carrying single-hop bandwidth request code word to the RS of single-hop bandwidth request code word correspondence and the higher level RS of this corresponding RS, RNG_RSP message can be that MR-BS sends to the RS of correspondence and the higher level RS of this correspondence RS separately, also can be the higher level RS that sends to this correspondence RS earlier, through certain processing the RNG_RSP message content is transmitted to this correspondence RS again.
The form of table 1 TLV in RNG_RSP
Step S202, the RS of subordinate sends bandwidth request ranging code to RS.
Step S203, RS judge whether the bandwidth request ranging code of the RS of the subordinate transmission that receives is single-hop bandwidth request code word.
Step S204, if RS judgement reception is single-hop bandwidth request code word, then RS is that the RS of subordinate distributes bandwidth.
Step S205, the RS of subordinate sends bandwidth request or data by the bandwidth that RS distributes to RS.
Step S206, if RS judgement reception is multi-hop bandwidth request code word, then RS continues to the superior node bandwidth on demand.The embodiment of the invention has proposed two kinds to the mode that continues to the superior node bandwidth on demand:
Mode one: as shown in Figure 3, the embodiment of the invention continues to use in the flow chart of CDMA sign indicating number bandwidth request mode, RS is after receiving the multi-hop bandwidth request code word of the RS of subordinate, needn't wait for the bandwidth request of the RS of subordinate, directly continue to send multi-hop bandwidth request code word to superior node (higher level RS or MR-BS), and RS distributes bandwidth for the RS of subordinate, and the RS of subordinate sends bandwidth request or data by the bandwidth that RS distributes.Same superior node (higher level RS or MR-BS) also distributes bandwidth for RS after receiving the multi-hop bandwidth request code word of RS.
Mode two: embodiment of the invention utilized bandwidth is as shown in Figure 4 stolen the flow chart of request mode, and RS at first distributes bandwidth for the RS of subordinate after receiving the multi-hop bandwidth request code word of the RS of subordinate; The RS of subordinate sends bandwidth request or data in the bandwidth that RS distributes; After the bandwidth request or data arrival RS that the RS of subordinate sends, RS needn't send CDMA sign indicating number bandwidth on demand, but utilizes the uplink bandwidth of having distributed to oneself directly to superior node (higher level RS or MR-BS) bandwidth on demand or transmission data.
Step S207, after MR-BS received the bandwidth request that RS sends, MR-BS distributed the bandwidth of MR-BS to the RS link.
By the above-mentioned bandwidth request method of the embodiment of the invention, receive the bandwidth request ranging code of the RS of subordinate at RS after, can according to this bandwidth request ranging code judge whether the RS of this subordinate only requires that RS distributes and the RS of subordinate between bandwidth; If this only requires the bandwidth between RS distribution and the RS of subordinate, RS only needs get final product for the RS of subordinate distributes bandwidth according to bandwidth request so, need not to continue to send bandwidth request to MR-BS or superior node.Thereby simplified the single-hop procedure of bandwidth request, avoided bandwidth waste.
The bandwidth request method flow diagram of the embodiment of the invention two as shown in Figure 5, MS carries out wireless connections by one-level RS and MR-BS at least among this embodiment, may further comprise the steps
Step S501, the MR-BS RNG-RSP message during by initial ranging is distributed bandwidth request ranging code to RS.RS just can distinguish single-hop bandwidth request code word and multi-hop bandwidth request code word after receiving the bandwidth request ranging code that MR-BS distributes.Single-hop bandwidth request code word only ask and superior node between the bandwidth of up link; Multi-hop bandwidth request code word not only ask and superior node between the bandwidth of up link, the multi-hop link upstream bandwidth between request and the MR-BS also.
Step S502, MS sends bandwidth request ranging code to RS.
Step S503 inserts RS and distributes bandwidth to MS.The access RS of MS owing to insert the type that RS can't judge the MS bandwidth on demand, therefore must distribute bandwidth to MS earlier after the bandwidth request ranging code that receives the MS transmission.
Step S504, MS send bandwidth request or data to inserting RS in the bandwidth that inserts the RS distribution.If MS sends data to inserting RS in the bandwidth that inserts the RS distribution, insert then that RS can select or by the time superior node distribute with this data corresponding bandwidth after send again, perhaps select to steal bandwidth mode and these data sent to superior node in the bandwidth that superior node has distributed.
Step S505 judges according to the bandwidth request that inserts RS parsing MS whether MS only requires the bandwidth of distributing between described RS and the described MS.As a preferred embodiment, be specially according to inserting MAC (the Media Access Control that RS resolves bandwidth request, the medium access control) CID (Channel Identifier, the channel indicator) type in the head judges whether MS only requires the bandwidth of distributing between RS and the MS.
Step S506, if the CID type connects CID for transmission, then the MS application is the multi-hop link bandwidth, inserts RS and need continue to the superior node bandwidth on demand.Equally in this step, also can adopt Fig. 3 or dual mode shown in Figure 4 to the superior node bandwidth on demand.
Step S507, if CID is Basic CID or Primary CID, so at first inserting RS need be that MS distributes bandwidth according to bandwidth request.
Step S508, the content that sends message according to MS judges whether that needs continue to the superior node bandwidth application.
Step S509 is at inserting RS, inserting RS so and just need not to continue to the superior node bandwidth application if MS sends the content of message.
Step S510, if MS sends the content of message not at inserting RS, inserting RS so just needs to continue to the superior node bandwidth application.Equally in this step, also can adopt Fig. 3 or dual mode shown in Figure 4 to the superior node bandwidth on demand.
The above embodiment of the present invention can judge that MS request one hop link bandwidth still is the multi-hop link bandwidth according to the CID type in the bandwidth request MAC head that MS is sent, when judging MS request one hop link bandwidth is that described MS distributes bandwidth, need not to continue to send bandwidth request to MR-BS.Thereby simplified the single-hop procedure of bandwidth request, reduced bandwidth waste.
