Below, in conjunction with said method, system and device, technical scheme provided by the present invention is described in more detail.
Embodiment one
In this embodiment, the upstream data that need to retransmit is used as new data and sends and receive, idiographic flow as shown in Figure 5:
Step 501:UE sends upstream data by carrier wave F1 to Node B;
Step 502:Node B notice UE does not re-use the transmission that carrier wave F1 carries out upstream data;
In this step, Node B can perhaps adopt other forms of Notification Method by issue the absolute grant AG of a special authorization value " Zero_Grant " to UE, informs that UE carrier wave F1 has not been used further to send upstream data.
Step 503:UE checks whether the data that need re-transmission are arranged on the carrier wave F1, when finding the data that need retransmit are arranged, enters step 504;
When UE uses carrier wave F1 data are sent to Node B, to detect downstream feedback channel E-HICH afterwards, if UE do not receive in institute's preset time that Node B sends about the response message ACK of these data or directly received the response message NACK of this message, show that then mistake has appearred in the data of being transmitted in transmission course, Node B does not correctly receive these data, and UE need retransmit these data.
Step 504:UE selects new carrier wave for the upstream data that needs to retransmit, and the data that will need to retransmit send as new data on the new carrier wave of changing;
In this step, suppose that the carrier wave after the replacing is F2, need to prove that Node B can adopt the form that issues absolute grant AG to UE to come also can adopt other modes for UE distributes new carrier wave.So, in the UE side, the data that UE will need to retransmit are sent to pairing HARQ second transmitting element of carrier wave F2 from pairing HARQ first transmitting element of carrier wave F1, are specially: UE seeks a suitable process for the data that need to retransmit and transmits in HARQ second transmitting element.In this simultaneously, in Node B side, Node B discharges the buffer memory in HARQ first receiving element, wherein, this buffer memory is used to deposit received misdata, so that merge with this partial data that retransmits, to improve the accuracy of transfer of data, and after this buffer memory discharged, the misdata that receives of Node B will not exist before, and this part data of re-transmission will be received as new data.Therefore, this part data that need to retransmit directly are set to 0 and get final product when carrying out being provided with of re-transmission sequence number numbering.
Wherein, the top data of mentioning for needing to retransmit can further be specially in suitable process of searching on the carrier wave F2: seek one near the idle process that comes in the HARQ process of data on carrier wave F2 that retransmits for needs, if all the HARQ processes promptly on the carrier wave F2 all have the data retransmission of this carrier wave to send, the carrier wave data retransmission of sending out on the F1 that changes just needs to wait for, until there being idle process to occur, and in case idle process occurs, the new data that the carrier wave data retransmission will have precedence on the F2 that changes on the F1 sends so, if but overlong time of waiting for and the number of times that exceeded preset time or re-transmission have surpassed the predetermined times restriction, then data retransmission will be abandoned.
The technical scheme that this embodiment provided is taked to seek an idle process that reaches the soonest for needing to retransmit upstream data on the primary carrier on new carrier wave, and utilize this idle process to carry out the re-transmission of upstream data, thereby realized under the multicarrier access module technique effect that upstream data still can normally retransmit after carrier wave is changed.
Embodiment two
In this embodiment, the upstream data that need to retransmit adopts to be attempted continuing to keep the mode of soft merging to retransmit and receive, idiographic flow as shown in Figure 5:
Step 601:UE sends upstream data by carrier wave F1 to Node B;
Step 602:Node B notice UE does not re-use the transmission that carrier wave F1 carries out upstream data;
In this step, Node B can perhaps adopt other forms of Notification Method by issue the absolute grant AG of a special authorization value " Zero_Grant " to UE, informs that UE carrier wave F1 has not been used further to send upstream data.
Step 603:UE checks whether the data that need re-transmission are arranged on the carrier wave F1, when finding the data that need retransmit are arranged, enters step 604;
When UE uses carrier wave F1 data are sent to Node B, to detect downstream feedback channel E-HICH afterwards, if UE do not receive in institute's preset time that Node B sends about the response message ACK of these data or directly received the response message NACK of this message, show that then mistake has appearred in the data of being transmitted in transmission course, Node B does not correctly receive these data, and UE need retransmit these data.
Step 604:UE selects new carrier wave for the upstream data that need to retransmit, and the data that needs are retransmitted retransmit on the carrier wave of changing and carry out soft merging on Node B.
In this step, suppose that the carrier wave after the replacing is F2, at this moment, carrier wave F1 and carrier wave F2 need satisfy a condition, and promptly both keep synchronous on process.Simultaneously, realizing changing carrier wave retransmits upstream data and sends the soft merging of misdata at Node B end, also must meet the following conditions: retransmitting upstream data must be consistent with the process that sends on primary carrier F1 in the process that sends on the carrier wave F2, consistent two processes that are meant of so-called herein process need to differ the integral multiple of a RTT in time, if and find that this condition can't satisfy, then can't realize changing the soft merging that carrier wave retransmits upstream data, will be as among the embodiment one, the data that needs are retransmitted transmit as new data; If this condition satisfies, so, in the UE side, the data that UE will need to retransmit are sent to pairing HARQ second transmitting element of carrier wave F2 from pairing HARQ first transmitting element of carrier wave F1, simultaneously, in Node B side, Node B is also with data cached pairing HARQ second receiving element of carrier wave F2 that sends to of the soft merging of pairing HARQ first receiving element of carrier wave F1.
In retransmission processes, re-transmission sequence number need be added up on the basis of former re-transmission number of times, the upstream data that HARQ second transmitting element of UE side will need to retransmit is sent to HARQ second receiving element of Node B side, and realize carrying out soft merging, thereby the accuracy of raising transfer of data with wherein wrong data cached.
The technical scheme that this embodiment provided is by distributing a new carrier wave synchronous with primary carrier for the upstream data that needs on the primary carrier to retransmit, and be that described upstream data is sought a suitable idle process on this new carrier wave, and the process number of this idle process needs identical with the process number of described upstream data on primary carrier, afterwards, utilize this idle process to carry out the re-transmission and the soft merging of upstream data, thereby realized under the multicarrier access module technique effect that upstream data still can normally retransmit after carrier wave is changed.
One of ordinary skill in the art will appreciate that all or part of step that realizes in the said method execution mode is to instruct relevant hardware to finish by program, described program can be stored in the computer read/write memory medium, here the alleged storage medium that gets, as: ROM/RAM, magnetic disc, CD etc.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the present invention.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined herein General Principle can realize under the situation that does not break away from the spirit or scope of the present invention in other embodiments.Therefore, the present invention will can not be restricted to these embodiment shown in this article, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
