The HARQ process of HARQ ID 6 sends TB1 to terminal 12, and the HARQ process of HARQ ID 7 is sent to terminal 12 The HARQ process of TB4, HARQ ID 8 sends TB7 to terminal 12.Terminal 12 carries out CRC check after receiving TB1, verifies successfully, TB1's is fed back to ACK in semi-static HARQ code book 1；, terminal 12 carries out CRC check after receiving TB4, verifies successfully, and half is quiet TB3 is fed back to ACK in state HARQ code book 1, and terminal 12 carries out CRC check after receiving TB7, verifies successfully, semi-static HARQ TB7's is fed back to ACK in code book 1.
After access network equipment 11 receives semi-static HARQ code book 1, since the feedback of TB1, TB4 and TB7 are ACK, The HARQ process of HARQ ID 6 sends new data TB3 to terminal 12, and the HARQ process of HARQ ID 7 sends new number to terminal 12 According to TB5, the HARQ process of HARQ ID 8 sends new data TB to terminal 12.There is noncontinuity transmitting in the scheduling of new data TB3 The DCI that (discontinuous transmission, DTX), i.e. terminal 12 do not receive TB3, terminal 12 can not obtain TB3 Running time-frequency resource, cause terminal 12 not receive TB3, TB3 is fed back to NACK in semi-static HARQ code book 2 at this time.Terminal 12 CRC check is carried out after receiving TB5, is verified successfully, TB5's is fed back to ACK in semi-static HARQ code book 2；Terminal 12 receives CRC check is carried out after TB8, is verified successfully, and TB8's is fed back to ACK in semi-static HARQ code book 2.
After access network equipment 11 receives semi-static HARQ code book 2, due to the NACK that is fed back to of TB3, HARQ ID's 6 HARQ process can send the 1st re-transmission of TB3 to terminal 12；Since the feedback of TB5 and TB8 is ACK, HARQ ID's 7 HARQ process can send new data TB6 to terminal 12, and the HARQ process of HARQ ID 8 can send new data TB9 to terminal 12.Eventually After end 12 receives the 1st re-transmission of TB3, since terminal 12 is not received by the first biography of TB3, to the 1st re-transmission CRC of TB3 Verification fails, and TB3's is fed back to NACK in semi-static HARQ code book 3；Terminal 12, which receives, carries out CRC check after TB6, verification at Function, TB6's is fed back to ACK in semi-static HARQ code book 3；There is DTX in the scheduling of new data TB3, at this time semi-static HARQ code book TB3's is fed back to NACK in 2.
By Fig. 2A, it can be seen that after DTX occurs for the first biography of TB3, the 1st re-transmission of TB3 fails, and due to terminal 12 The first biography of TB3 is not received, and the later retransmission of TB3 will fail always.
In the related technology, a kind of scheme of reply re-transmission failure is provided.After terminal 12 receives re-transmission, use is same The TBS for the TB that HARQ process the last time receives goes CRC check.After terminal 12 receives the 1st re-transmission of TB3, terminal 12 use same HARQ process, and the TBS for the TB that the last time receives goes to carry out TB3 CRC check, i.e. terminal 12 uses TB1 TBS go to TB3 carry out CRC check.
There are the following problems for the program: TB1 and TB3 is two different TB, and the TBS of TB1 may be with the TBS of TB3 not Together, when TBS difference, terminal 12 is still failure to the CRC check of TB3.
The embodiment of the present application provides a kind of scheme that data success rate is improved in the semi-static feedback mechanism of HARQ.The party Whether case includes two parts, and first part is identification DTX, had occurred by the scheduling that identification just passes when retransmitting of terminal 12 DTX, or in first pass identify whether that DTX has occurred by terminal 12；Second part is the number of DTX reported and DTX occurs According to issue, the case where DTX that terminal 12 will recognize, is reported to access network equipment 11, and DTX occurs for the positioning of access network equipment 11 Data, the data of generation DTX are sent to terminal 12 in the way of just passing, thus solve just pass scheduling occur DTX, The problem of causing later retransmission to fail.
It should be noted that DTX occurs for a TB in the embodiment of the present application, it can be understood as, the scheduling of the TB occurs DTX or terminal do not receive the DCI of the TB.Semi-static HARQ code book is one of HARQ mechanism feedback model, anti-at this In feedback mode, using semi-static mode to the reception state of access network equipment feedback TB, semi-static HARQ code book can claim terminal For semi-static HARQ code book or semi-static code book.MCS, RV or NDI of TB, it can be understood as, DCI letter corresponding with TB MCS, RV or NDI of TB in breath.
The first embodiment of the embodiment of the present application identification DTX is introduced below according to Fig. 3.
S301: access network equipment 11 sends Downlink Control Information (downlink control to terminal 12 Information, DCI).
Optionally, terminal can save the DCI.
For example, terminal 12 can pass through Physical Downlink Control Channel (physical downlink control Channel, PDCCH) from access network equipment 11 receive DCI.
DCI includes resource allocation information, hybrid automatic repeat-request (hybrid automatic repeat request, HARQ the control information of (identifier, ID) and data block (transport block, TB), the control of the TB) are identified Information includes Modulation and Coding Scheme (modulation and coding scheme, MCS), and new data indicates (new data Indicator, NDI), redundancy versions (redundancy version, RV).
For example, the HARQ ID of a HARQ process is 6, current transmission block is TB3, and terminal 12 is received from access network equipment 11 DCI3, DCI3 may include following information:
(1) resource allocation information of TB3, the distribution information of time domain, frequency domain including TB3；

Terminal 12 obtains QAM information, for example, terminal 12 obtains QAM information by RRC reconfiguration message, such as passes through RRC Cellgroupconfig acquisition of information in reconfiguration message, the RRC reconfiguration message in user's access procedure or can be cut Change process；Or terminal 12 can judge QAM information according to the mapping table of MCS and MCS and QAM.
It should be noted that communication system can configure under each QAM, under the MCS for just passing and retransmitting, different Q AM, MCS for just passing and retransmitting can be different.Here can be according to the QAM information of terminal 12, and the MCS of current TB, judgement Whether current TB is re-transmission, and the embodiment of the present application is not construed as limiting the numerical value of QAM, the numerical value of the MCS for re-transmission.In addition, logical Letter system can configure the RV of the RV and re-transmission that just pass, here can according to the RV information of terminal 12, judge current TB whether be It retransmits, the embodiment of the present application is not construed as limiting the numerical value of RV.
For example, if QAM is 64, terminal 12 judges whether the MCS of current TB is 29-31, if so, MCS instruction retransmits；If QAM is 256, and terminal 12 judges whether the MCS of current TB is 28-31, if so, MCS instruction retransmits；
Alternatively, terminal 12 judges whether the RV of current TB is more than or equal to 1, if it is greater than or equal to 1, then RV instruction is retransmitted.
For example, the MCS that the QAM of terminal 12 is 64, TB3 is 29, illustrate that the MCS instruction of TB3 retransmits；Alternatively, the RV of TB3 is 1, illustrate that the RV instruction of TB3 retransmits, TB3 is to retransmit.
About judging whether the TB is re-transmission, the embodiment of the present application provides second of implementation, the first realization side Formula may include:
Firstly, terminal 12 is in semi-static HARQ code book, if not receiving some TB in semi-static code book, terminal 12 record the relevant information of the TB not received, such as record the HARQ process number of not received TB, and No. TB etc..
For example, terminal 12 in last time semi-static HARQ code book, does not receive the first biography of TB3, terminal 12 saves TB3's The relevant information just passed, such as HARQ ID 6, TB3 etc..
Secondly, terminal 12 judges under the HARQ process of current TB, the information of the TB of the last time transmission, if the last pass Defeated TB terminal 12 does not receive, then current TB is to retransmit.
For example, judging that the last TB transmitted is TB3 under same HARQ process, terminal 12 after terminal 12 receives TB3 TB3 is not received, then current TB3 is to retransmit.
DTX occurs about the scheduling just passed, the embodiment of the present application provides a kind of implementation:
When TB is to retransmit, terminal 12 judges the TB's that the NDI of current TB and same HARQ process the last time are received Whether NDI is identical, if it is different, illustrating that DTX occurs for the scheduling of the first biography of the TB；If they are the same, illustrate the scheduling of first biography of the TB not DTX occurs.The NDI for the TB that the NDI of current TB and same HARQ process the last time receive not can be understood as NDI simultaneously Overturning, the NDI of current TB can be understood as NDI when identical as the NDI of TB that same HARQ process the last time receives and do not turn over Turn.
Terminal 12 judges whether the NDI for the TB that the NDI of current TB and same HARQ process the last time receive is identical, In, the NDI of current TB can be obtained from the corresponding DCI of current TB；The NDI for the TB that same HARQ process the last time receives It can be obtained from the corresponding DCI of TB that same HARQ process the last time receives, such as terminal 12 is received in the last time To same HARQ process DCI when, save it in terminal 12, terminal is according to the resource allocation information of the DCI corresponding TB is received in resource, and received TB is stored in terminal 12.
For example, current TB is TB3, according to DCI3, the NDI of TB3 is 1.Belong to same HARQ process with TB3, terminal 12 is most The TB closely once received is TB1, and it is DCI1, the NDI of the NDI and TB1 of DCI1 0, TB3 are or not terminal 12, which obtains the DCI of TB1, Together.
The TB that the NDI of current TB and same HARQ process the last time receive is not identical, illustrate current TB with it is same The data for the TB transmission that HARQ process the last time receives are different, and current TB is to retransmit.Illustrate that access network equipment 11 is not Current TB is sent to terminal 12 for the first time, that is to say, that before sending current TB to terminal 12 by same HARQ process, is connect Log equipment 11 is transmitted across DCI and TB to terminal 12, and (MCS or RV refers to the first biography which is current TB in the DCI of the TB Show just biography, and the NDI of the TB is different from the NDI of TB that same HARQ process the last time receives), but terminal 12 does not have The DCI is received, leads to not receive the TB in the resource indicated according to the DCI, that is, when the first biography of the current TB of descending scheduling DTX has occurred.
For example, illustrate TB3 and TB1 transmission is different data since the NDI that the NDI of TB3 is 1, TB1 is 0, wherein TB1 is that terminal 12 is received in same HARQ process the last time.However, the MCS and RV of TB3 indicate to retransmit.Illustrate Between TB1 and TB3, access network equipment 11 may be had sent to terminal 12 TB3 first biography (NDI of the first biography of TB3 be 1, MCS be 0-28, RV 0), but terminal 12 is not received by the DCI of the first biography of TB3, the money for causing terminal 12 that can not be indicated according to DCI Source receives the first biography of TB3, that is, DTX has occurred when the first biography of descending scheduling TB3.
Terminal 12 is when receiving TB, in conjunction with MCS, RV, the information for the transmission of same HARQ process last time that terminal 12 saves And it is put into one or more in NDI, judge whether it is re-transmission, and it just passes and DTX has occurred, accurate can must identify current Whether the first biography retransmitted has occurred DTX.
The embodiment of the present application provides the method for another identification DTX, and as shown in Figure 3B, this method is to semi-static HARQ Each TB is judged in code book, judges whether terminal 12 does not receive, if not receiving, DTX is had occurred in the scheduling of the TB.
