Embodiment
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, and below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
According to the decode results of ACK/NACK field in this decoding, the embodiment of the present invention can determine whether that needing to initiate MAC retransmits, if do not needed, then can not initiate MAC and retransmit, thus can avoid introducing unnecessary MAC re-transmission.
Embodiment one:
UE, after the downlink data receiving base station transmission, sends to base station by HS-SICH after the feedback information being used for the reception condition feeding back HS-DSCH can being encoded.The information spinner that HS-SICH carries is wanted to comprise: RMF field, RTBS field and ACK/NACK field.But above-mentioned field information does not adopt the coded system of carrying check information, and therefore when channel circumstance is poor, HS-SICH decoding may occur mistake, and namely HS-SICH decoding is unreliable.
At present, when HS-SICH decoding is unreliable, in order to reduce the impact of generation as far as possible, no matter decode results, all according to NACK process, initiating MAC and retransmitting.As shown in Figure 1, be the flow chart of the processing method of HS-SICH decoding in prior art, the method can comprise:
Step 100, HS-SICH decoding.
Step 102, judges that whether decoding is reliable.
If so, then step 104 is performed; Otherwise perform step 106.
Step 104, according to normal process flow processing, terminates after processing.
Step 106, initiates MAC and retransmits, terminate after processing.
Although said method can be avoided introducing RLC and retransmit, and reduces the impact that RLC retransmits, a large amount of MAC retransmits the throughput that also can reduce system, the performance of influential system.
For the problems referred to above, the embodiment of the present invention proposes a kind of processing method of high-speed shared information channel decoding, and the method can avoid the MAC introducing great quantities of spare to retransmit, the performance of elevator system.
With reference to Fig. 2, show the flow chart of the processing method of a kind of HS-SICH decoding described in the embodiment of the present invention one, described method can comprise:
Step 200, detects the decoded state of high-speed shared information channel, judges that whether this decoding of described high-speed shared information channel is reliable.
The RMF field, RTBS field and the ACK/NACK field that carry due to HS-SICH do not adopt carry check information coded system (such as, add cyclic redundancy check (CRC) (CyclicalRedundancyCheck, CRC) re-encoding afterwards), therefore, when channel circumstance is poor, HS-SICH decoding possibility is also unreliable.
The decoded state of high-speed shared information channel can be detected in the embodiment of the present invention in real time, and judge that whether this decoding of described high-speed shared information channel is reliable.
If this decoding of HS-SICH is reliable, then can process according to normal process flow process.Such as, if the decode results of ACK/NACK field is ACK in this decoding, then can dispatch according to the decode results of this decoding, namely the modulating mode can recommended according to the decode results of RMF field in this decoding is modulated, the transmission block size of recommending according to the decode results of RTBS field in this decoding is transmitted, etc.
If this decoding of HS-SICH is unreliable, then can perform following steps, carry out decoding unreliable time subsequent treatment.The improvement that subsequent processes when the embodiment of the present invention is mainly unreliable for HS-SICH decoding is carried out.
Step 202, when this decoding is unreliable, detects the decode results of ACK/NACK field in this decoding.
When this decoding of HS-SICH is unreliable, the decode results of this decoding can be obtained, and detect the decode results of ACK/NACK field in this decoding, different operations can be performed according to the difference of ACK/NACK Coding of numeric segment result.
Step 204, when the decode results of described ACK/NACK field is NACK, initiates MAC and retransmits.
When the decode results of described ACK/NACK field is NACK (ACK mistranslation is NACK), base station then can think that UE does not correctly receive the downlink data of base station transmission, now namely can initiate MAC and retransmit.
Step 206, when the decode results of described ACK/NACK field is ACK, does not initiate MAC and retransmits, and obtain the decode results of RTBS field in the decode results of RMF field in decoding last time and decoding last time.
Step 208, performs corresponding operating according to the decode results of RTBS field in the decode results of RMF field in described decoding last time and decoding last time.
When the decode results of described ACK/NACK field is ACK (NACK mistranslation is ACK), now can't initiates RLC and retransmit, also temporarily not initiate MAC simultaneously and retransmit.But the decode results of RTBS field in the decode results of RMF field in decoding last time and decoding last time can be obtained, and perform corresponding operating according to the decode results of RTBS field in the decode results of RMF field in described decoding last time and decoding last time.Such as, initiate MAC and retransmit, or dispatch according to the decode results of this decoding, or dispatch according to the decode results of decoding last time, etc.
For the detailed process of each step above-mentioned, will introduce in detail in the following embodiments.
The embodiment of the present invention is when judging that this decoding is unreliable, be not directly initiate MAC to retransmit, but determine whether that needing to initiate MAC retransmits according to the decode results of ACK/NACK field in this decoding, then corresponding operating is performed, thus can avoid introducing unnecessary MAC re-transmission, the performance of elevator system.Further, the embodiment of the present invention can also perform corresponding operating according to the decode results of decoding last time to this decode procedure, thus can reduce the suddenly saltus step of the service rate of makeing mistakes and causing due to RMF field and RTBS Coding of numeric segment further.

When judging the decode results saltus step of RTBS field not obvious (namely not meeting RMF=lastRMF|RTBS-lastRTBS|>thresholdRTBS) in step 508, between the decode results that can judge RMF field in the decode results of RMF field in this decoding described and described decoding last time further, whether saltus step is obvious, namely judges whether in this step 510 to meet RMF=lastRMF.For concrete deterministic process, can with reference to the associated description of above-mentioned steps 408.
As RMF=lastRMF, between the decode results that RMF field in the decode results of RMF field in this decoding and decoding last time is described, saltus step is not obvious, otherwise illustrates that saltus step is obvious.
Step 512, initiates MAC and retransmits.
In the embodiment of the present invention, when the decode results detecting described ACK/NACK field in step 504 is NACK, or when the judged result of step 508 is for being (namely the decode results saltus step of RTBS field is obvious), or when the judged result of step 510 is for being (namely the decode results saltus step of RMF field is obvious), MAC can be initiated and retransmit.After re-transmission, then can terminate the process to this HS-SICH decoding.
Step 514, according to normal process flow processing.
When judging in step 502 that this decoding of HS-SICH is reliable, then can according to normal handling process process.For concrete processing procedure, the embodiment of the present invention is discussed no longer in detail at this.
In addition, when the judged result in step 510 is no (namely the decode results saltus step of RMF field is not obvious), also can according to normal process flow processing.Because the decode results of now ACK/NACK field is ACK, therefore, can dispatch according to the decode results of RTBS field in the decode results of RMF field in this decoding and this decoding.
For the concrete introduction of each step in Fig. 5, can with reference to above-described embodiment one and embodiment two, and to the associated description of Fig. 4 in the present embodiment, the embodiment of the present invention is discussed no longer in detail at this.
If this decoding of HS-SICH is unreliable in the embodiment of the present invention three, and when ACK/NACK field is translated into ACK in this decoding, temporarily can initiate MAC and retransmit.And the RMF/RTBS that this can be translated and the RMF/RTBS translated last time compares, and judges whether that saltus step is obvious.If one of them saltus step is obvious, then can be used as NACK process, initiate MAC and retransmit; Otherwise normal process can be carried out according to the decode results of this decoding.The embodiment of the present invention decreases unnecessary MAC on the one hand and retransmits, and improves the performance of system; On the other hand, by by this decode results and last time decode results compare, if saltus step is not obvious, then can process according to the result of this decoding, thus the problem that the service rate of makeing mistakes due to RMF field and RTBS Coding of numeric segment and causing skyrockets or suddenly falls can be prevented.
