Description

Resource block location method of adjustment and system

Technical field

The present invention relates to the communications field, and especially, relate to a kind of resource block location method of adjustment and system.

Background technology

Micro-wave access to global intercommunication (World Interoperability for MicrowaveAccess, WiMAX) in the system, base station (Base Station, BS) and travelling carriage (MobileStation, MS) information exchange between need distribute the corresponding uplink and downlink resource, and the distribution of resource and release are indicated by resource mapping (MAP) message.

For periodicity and packet size and the geostationary business of modulating-coding digit rate (MCS), adopted the method for a kind of persistent assignments (Persistent Allocation abbreviates PA as) to come management resource in the WiMAX system.When periodic traffic begins, BS distributes fixing resource to give MS, and transmission comprises the MAP message of PA distribution accordingly to MS, this resource allocation message only sends once when beginning, the fixed resource that MS utilization is afterwards distributed to it comes transceive data, and the PA that just stops this when resource release or resource changing distributes.Therefore, the method for PA distribution can significantly reduce the expense of the MAP message of resource allocation.

But, because MAP message only sends out once, can correctly receive most important, so MS need be to the reception condition of BS feedback acknowledgment MAP message.Divide timing when MS receives new PA, send positive feedback to BS and confirm (ACK) message (also can be called correct response message); When mistake appears in MS decoding MAP message, send negative feedback (NACK) message (also can be called error feedback message) to BS.BS determines how to send next bar MAP message according to the feedback of MS.

When the PA of part MS resource discharges, some resource cavities can appear in the range of distribution of PA, and can adopt the mode that all Resource Block behind the resource cavity are moved to come filling cavity usually forward.

Fig. 1 schematically shows the present processing procedure of filling up the resource cavity.As shown in Figure 1, BS sends MAP message at frame K and comes instruct MS 1 to discharge resource and concrete resource block location and size, and BS indicates and need filling cavity, and this moment, BS and MS just came transceive data according to the resource location behind the hole-filling; Specifically, be exactly that MS2 and MS3 move its resource block location and fill up MS1 and discharge the cavity of causing after the resource.With reference to the accompanying drawings 1, MS2 makes mistakes in frame K decoding MAP message, so MS2 stops data transmit-receive immediately, and sends NACK to BS behind two frames, and BS will send new MAP message and indicate PA to recover (in the frame K+4 moment).Before PA recovered, the data of MS2 had just been lost.

In the middle of the processing of mobile resources position, under the situation that does not obtain the affirmation of MS reception MAP message feedback, just begin to use new PA in the above-mentioned filling cavity, therefore, in case MAP source codec mistake will cause loss of data.The technical scheme that can address this problem is proposed at present as yet.

Summary of the invention

Consider the problems referred to above and make the present invention, for this reason, main purpose of the present invention is to provide a kind of resource block location to adjust mechanism, the problem that the terminal data that occurs when solving mobile resources position in the correlation technique is lost.

According to embodiments of the invention, a kind of resource block location method of adjustment is provided, filling cavity is come in the position that is used for adjustment Resource Block under the situation that discharges Resource Block generation resource cavity.

Embodiment

Method embodiment

In the present embodiment, provide a kind of resource block location method of adjustment, be used under the situation that discharges Resource Block generation resource cavity, adjusting the position of Resource Block.

As shown in Figure 2, comprise according to the resource block location method of adjustment of present embodiment: step S202, BS is notified to MS by mapping message with the entry-into-force time that the size of the Resource Block that discharges and position and Resource Block move; Step S204, MS and BS utilize the adjusted Resource Block in position to carry out data transmit-receive when the entry-into-force time arrives according to mapping message.

Wherein, the entry-into-force time is that BS sends the current time that fixed time after current time of mapping message or BS send mapping message, wherein, the fixed time at MS after BS sends time of error feedback message of mapping message.

And, in the entry-into-force time is under the situation of the fixed time after BS sends current time of mapping message, before at the appointed time arriving, Resource Block before MS utilizes BS to the position adjustment of its distribution carries out data transmit-receive, and utilizes the adjusted Resource Block in position to carry out data transmit-receive when at the appointed time arriving.

In addition, in the entry-into-force time is under the situation of the fixed time after BS sends current time of mapping message, if MS resolves the mapping message failure, MS replys error feedback message to BS, wherein, the fixed time at MS after BS sends the time of error feedback message, and, before at the appointed time arriving, the Resource Block before MS utilizes BS to the position adjustment of its distribution carries out data transmit-receive.In addition, when at the appointed time arriving, other MS that this BS is down correct the to resolve mapping message Resource Block before the adjustment of position and BS equally carries out data transmit-receive.

Afterwards, in response to error feedback message, BS resends mapping message to MS as recovering information.

Next, after MS sent error feedback message, if MS correctly receives the mapping message of repeating transmission, when then at the appointed time arriving, MS and BS utilized the adjusted Resource Block in position to carry out data transmit-receive.In addition, when at the appointed time arriving, then adjusted Resource Block and BS carry out data transmit-receive to other MS of the correct down parsing mapping message of this BS in the position.

On the other hand, after MS sends error feedback message, if MS resolves the mapping message failure of retransmitting, when then at the appointed time arriving, MS stops data transmit-receive, and BS descends other MS that correctly resolves mapping message, and then adjusted Resource Block and BS carry out data transmit-receive in the position.

Preferably, before BS sent mapping message, this method can further comprise: BS selects current time or fixed time as the entry-into-force time according to the demand of business.

That is to say, if current business is not very sensitive to packet loss, the mode that BS still can adopt original mapping message to come into force; And if current business is very sensitive to packet loss, then BS can adopt mode that delay according to the present invention comes into force to avoid packet loss.Therefore, the present invention can combine with current mechanism well.

In the middle of practical application, suppose that the current time is T1, the above-mentioned fixed time is T2, and the error feedback time is T3, and wherein, time T 3 is between time T 1 and T2.

BS sends at current time T1 and comprises the MAP message that new PA distributes, and indicates some MS to discharge the position and the size of its Resource Block and Resource Block; Simultaneously, the MS that indicates other in this MAP message will move its resource block location and fills up Resource Block and discharge the cavity of causing.

As mentioned above, BS increases an indication information in above-mentioned MAP message, when moves with specified resource piece position and comes into force.Entry-into-force time is divided into two kinds, and a kind of is to come into force at current time T1, and another kind is that the fixed time T2 after the current time comes into force.

If T1 comes into force in the current time, the new resource location after BS and MS (all are correctly decoded the MS of above-mentioned MAP message) enable Resource Block at once and move comes transceive data.If certain MS is not correctly decoded the MAP message that BS sends at current time T1, this MS will stop transceive data.This MS will send feedback message NACK with notice BS at later time T3.BS receives this NACK message, just sends the MAP message that comprises PA recovering information (information of T1 time) and gives this MS.So this MS will come transceive data according to the resource block location of PA recovering information indication.

If the T2 time that above-mentioned MAP message specified resource piece moved after the current time comes into force, before the T2 time arrived, BS and MS came transceive data according to original resource block location; When the T2 time arrived, the new resource location after BS and MS just enable Resource Block and move came transceive data.

Under the situation about coming into force in the T2 time, if MS is not correctly decoded the MAP message that BS sends at current time T1, this MS will send feedback message NACK with notice BS at later time T3, and the T3 time is at T2 before the time.BS receives this NACK message, just sends the MAP message that comprises PA recovering information (the MAP information that is sent of T1 time) and gives MS, and this MS and other MS will enable new resource location in the T2 time and come transceive data.From the T1 time to T2 before the time, this MS still distributes to come transceive data according to original PA, does not stop data transmit-receive.If this MS does not still receive the MAP message of carrying the PA recovering information in the T2 time, this MS just stops transceive data.

As can be seen, move by above-mentioned Resource Block and to postpone the method come into force, can be under MS decodes the situation that above-mentioned MAP message makes mistakes, by keeping original resource allocation, with the transfer of data of assurance MS (comprising the MS that makes mistakes), and before arriving, give the entry-into-force time MS that makes mistakes to recover the chance of PA.

Below in conjunction with instantiation the present invention is described.

Example 1

In this example, as shown in Figure 3, BS sends at current time T1 and comprises the MAP message that new PA distributes, indication discharges the Resource Block of MS1 and the position and the size of Resource Block, and the MS that indicates other will move its resource block location and fill up Resource Block and discharge the cavity cause, and the entry-into-force time that the explanation resource moves in this MAP message is T2 simultaneously.

According to Fig. 3, in the T1 time, MS2 is not correctly decoded the above-mentioned MAP message that BS sends, and MS2 will send feedback message NACK with notice BS at later time T3.MS2 makes mistakes in T1 time decoder MAP message and does not but stop data transmit-receive.

According to Fig. 3, BS receives the NACK message that above-mentioned MS2 sends, and just sends the MAP message that comprises PA recovering information (information of T1 time) and gives MS, and MS2 and MS3 will and enable new resource location and come transceive data at T2 time mobile resources piece.Accordingly, BS also enables new resource location in the T2 time and comes transceive data.

According to Fig. 3, from the T1 time to T2 before the time, MS2 and MS3 distribute to come transceive data according to original PA.Accordingly, BS also distributes to come transceive data according to original PA.

As seen, the present invention compares with the prior art scheme, can guarantee the transfer of data of MS, not obliterated data under the situation that the MAP decoding makes mistakes.

Example 2

In this example, as shown in Figure 4, BS sends at current time T1 and comprises the MAP message that new PA distributes, indication discharges the Resource Block of MS1 and the position and the size of Resource Block, and the MS that indicates other will move its resource block location and fill up Resource Block and discharge the cavity cause, and the entry-into-force time that the explanation resource moves in this MAP message is T2 simultaneously.

According to Fig. 4, in the T1 time, MS2 is not correctly decoded the above-mentioned MAP message that BS sends, and MS2 will send feedback message NACK with notice BS at later time T3.MS2 makes mistakes in T1 time decoder MAP message and does not but stop data transmit-receive.

According to Fig. 4, BS receives the NACK message that above-mentioned MS2 sends, and just sends the MAP message that comprises PA recovering information (information of T1 time) and gives MS.

According to Fig. 4, from the T1 time to T2 before the time, MS2 and MS3 distribute to come transceive data according to original PA.Accordingly, BS also distributes to come transceive data according to original PA.

According to Fig. 4, when the T2 time arrived, the MS2 MAP message of still decoding was made mistakes, and MS2 stops data transmit-receive.At this moment, MS3 mobile resources piece and on new resource location transceive data.Accordingly, BS also enables new resource location in the T2 time and comes transceive data.

In the time will the entry-into-force time notifying MS, can adopt modes such as relative frame number, frame number, time indicating bit to notify, concrete mode is as follows:

Alternatively, carry the required information such as parameter of mobile resources piece by increase the indicator element Resource shifting executing time indicator that a resource moves the entry-into-force time in MAP message, concrete indicating mode can be shown in table 1 (YYY-Persistent DLHARQ Chase Subburst IE form):
