Embodiment

To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the embodiment of the present invention In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is Part of the embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art The every other embodiment obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.

Various embodiments of the present invention be applied to exempt from authorized transmissions pattern, terminal to the network equipment send data before, without to Base station requests scheduling resource, therefore, the network equipment can not know the mark for the terminal for sending the data before decoding obtains data.

Fig. 1 is the flow chart for the data transmission method that one embodiment of the invention provides, as shown in figure 1, the side of the present embodiment Method can include：

S101, terminal determine to send the sequence number of the pilot tone of the first signal of the M times transmission.

M is the integer more than or equal to 1.

S102, terminal send the M times transmission using pilot tone corresponding to the sequence number according to the sequence number to the network equipment First signal.

In the present embodiment, terminal can determine to send the sequence number of the pilot tone of the first signal sent for the first time, or, second The sequence number of the pilot tone of first signal of secondary transmission, or, sequence number of pilot tone of the first signal that third time is sent etc..

Alternatively, if a kind of possible implementations of the M more than 1, S102 is：Terminal does not connect in preset time When receiving the confirmation message that the network equipment is sent, according to the sequence number, using pilot tone corresponding to the sequence number to the net The M times transmission first signal of network equipment；The confirmation message is used to confirm to have received first signal.It is, eventually Hold and judge whether the confirmation message for being used to confirm to have received the first signal for receiving network equipment transmission in preset time, if Confirmation message is received in preset time, then illustrates that the first signal succeeds and is decoded by the network equipment, then terminate；If default Confirmation message is not received in time, then illustrates that the first signal is received or decoded by the network equipment not successfully, then sends the again One signal, the present embodiment send the first signal as the M times the first signal of transmission again, and then terminal is according to the sequence determined in S101 Number, to the M times the first signal of transmission of the network equipment.

Alternatively, the first signal of the M times transmission is the m-th redundancy versions of the first signal or the first letter of repetition Number.

S103, the network equipment set first signal as n-th retransmission when failing to first signal interpretation First signal.

The N is the integer more than or equal to 1.

The signal for the failed decoding that S104, the network equipment receive according to preceding n times, enters at row decoding to first signal Reason.

In the present embodiment, after the network equipment receives the first signal, row decoding is entered to first signal, if to first letter It is number successfully decoded, then it can obtain the data that terminal is sent to the network equipment；If failing to the first signal interpretation, first is set Signal is the first signal of n-th retransmission, and N is the integer more than or equal to 1.Then the failed decoding received according to preceding n times Signal, row decoding processing is entered to the first signal of the n-th retransmission.

Alternatively, if the signal received according to preceding n times, when merging decoding failure to first signal, institute is updated It is N+1 to state N.The number of retransmissions of first signal is namely set as N+1, further according to the first N+1 times failed decoding received Signal, row decoding processing is entered to first signal, by that analogy.

Such as：For the network equipment when failing to the first signal interpretation, the network equipment sets the number of retransmissions of first signal For 1, row decoding processing is entered to first signal according to the signal of the failed decoding of first 1 time reception, if successfully decoded, to end End sends confirmation message, to confirm to receive first signal to terminal notification；If decoding failure, the weight of first signal is set Number 2 is passed, row decoding processing is entered to first signal according to the signal of the failed decoding of first 2 times receptions, if successfully decoded, Confirmation message is sent to terminal, to confirm to receive first signal to terminal notification；If decoding failure, first signal is set Number of retransmissions be 3, if maximum retransmission be 3, terminate, i.e., not further according to the signal of the failed decoding 3 times received Enter row decoding processing to first signal.Alternatively, the network equipment preserves the first signal that this is decoded not successfully.

The data transmission method that the present embodiment provides, passes through the first signal interpretation sent in the network equipment to receiving terminal During failure, first signal is set as to the first signal of n-th retransmission, the letter of the failed decoding received further according to preceding n times Number, row decoding processing is entered to the first signal of the n-th retransmission, it is achieved thereby that in the situation for the mark that can not know terminal Under, in failed decoded signal, the more parts of signals decoded not successfully can be merged to decoding processing to obtain data.

S304, the network equipment according to the sequence number of the pilot tone of the first signal of the n-th retransmission, pilot tone select rule and The number of retransmissions N of the current setting of first signal, the sequence number of the pilot tone for the first signal that n times receive before acquisition.

In the present embodiment, by N be 3 exemplified by, the network equipment according to the 3rd time re-transmission the first signal pilot tone signal, lead Frequency selects rule and number of retransmissions 3, obtains the sequence number of the pilot tone of the first signal 3 times received, that is, the 1st reception before obtaining The sequence number (be, for example, P1) of pilot tone of the first signal, preceding 2nd reception the first signal pilot tone sequence number (being, for example, P2) With the sequence number (being, for example, P3) of the pilot tone of the first signal of first 3rd time reception.

The sequence number of the pilot tone for the first signal that S305, the network equipment receive according to the preceding n times, is received from the preceding n times Failed decoding signal in, obtain the first signal that the preceding n times receive.

Such as：The serial number P1 of network equipment pilot tone of the 1st the first signal received before, the 1st reception of the past The serial number P1 of the signal acquisition pilot tone decoded not successfully signal is the first signal of first 1st time reception；The network equipment according to The serial number P2 of the pilot tone of preceding 2nd the first signal received, the signal acquisition pilot tone of the failed decoding of the 2nd reception of the past Serial number P2 signal is the first signal of first 2nd time reception；Network equipment pilot tone of the 3rd the first signal received before Serial number P3, the serial number P3 of the signal acquisition pilot tone of the failed decoding of the 3rd reception signal is first 3rd time reception in the past The first signal.

The first signal that S306, the network equipment receive according to the preceding n times, enters to the first signal of the n-th retransmission Row decoding processing.

Such as：The network equipment the first signal of the 1st reception, first signal and first 3rd time of preceding 2nd reception before The first signal received, row decoding processing is entered to the first signal of the 3rd re-transmission.

The possible implementation of the first of S306 is S3061, and S306 second of possible implementation includes S3061 And S3062.

S3061, the network equipment carry out the first signal that the preceding n times receive and the first signal of the n-th retransmission Merge decoding processing.

S3062, the network equipment reject any the first signal received in the first signal that the preceding n times receive, and obtain First signal of N-1 reception；First signal of described N-1 times reception and the first signal of the n-th retransmission are translated Code processing.

As shown in fig. 6, the sequence number of the pilot tone of the first signal transmitted every time is identical, terminal is at the beginning of moment t is to the network equipment Pass the first signal, the serial number 2 of pilot tone；Confirmation message of the terminal due to being not received by network equipment transmission, in next week Phase retransmit for the first time, selects the serial number 2 of identical pilot tone, is sent using pilot tone corresponding to sequence number 2 and retransmitted for the first time Signal；Transmission is still unsuccessful, and having carried out second in next cycle retransmits, and selects the serial number 2 of identical pilot tone, adopts The pilot tone corresponding to sequence number 2 sends second of signal retransmitted；Now there is another terminal also to be sent separately to the network equipment simultaneously One signal (is referred to as secondary signal), selects the serial number 3 of pilot tone, and secondary signal is sent using pilot tone corresponding to sequence number 3.Terminal is sent out Send the first signal still unsuccessful, having carried out third time in next cycle retransmits, and selects the serial number 2 of identical pilot tone, adopts Pilot tone sends the signal that third time retransmits corresponding to sequence number 2.

The network equipment have received signal in moment t, t+T, t+2T successively.After each signal progress pilot detection of reception, The serial number 2 of the pilot tone for the signal that moment t is received, the serial number pilot tone 2, t+ of the pilot tone for the signal that t+T is received are detected respectively The sequence number of the pilot tone for two signals that 2T is received is respectively pilot tone 2 and 2, but equal decoding failure.

Then, the network equipment receives signal in moment t+3T, after carrying out pilot detection to this signal, detects pilot tone Serial number 2, row decoding, but decoding failure are entered to this signal.

Then the signal that this signal retransmits as first time is set, the letter for the decoding failure that this signal and last time are received Number merge decoding processing, that is, the signal of the serial number 2 for the pilot tone that this signal was received with last time merges Decoding, equal decoding failure.

This signal is reset as second signal retransmitted, by entering for this signal and the signal of upper decoding failure twice Row merges decoding processing, that is, the signal of this signal and the serial number 2 of the upper pilot tone received twice is merged into decoding, Equal decoding failure.

The signal that this signal retransmits for third time is reset, by entering for this signal and the signal of upper decoding failure three times Row soft merging, that is, the sequence of the signal of the serial number 2 for the pilot tone that this signal and last time are received, the pilot tone that last time receives again Number for 2 signal and again last time receive the signal of serial number 2 of pilot tone and merge decoding, and the successfully decoded terminal that obtains is sent out Give the data of the network equipment.

Alternatively, the network equipment is when setting this signal as the signal of second of re-transmission, also by this signal and t+2T The signal of the serial number 2 of the pilot tone of reception merges decoding, and by this signal and the serial number of t+T moment pilot tones 2 signal merges decoding, equal decoding failure.When setting the signal that this signal retransmits as third time, also this is believed Number closed with the signal of the signal of the serial number 2 of the pilot tone of t+2T receptions and the serial number 2 of the pilot tone of t+T receptions And decode, the serial number for the pilot tone that the signal and t of this signal and the serial number 2 of the pilot tone of t+2T receptions are received 2 signal merges decoding, and the signal and t of this signal and the serial number 2 of the pilot tone of t+T receptions are received The signal of the serial number 2 of pilot tone merges decoding.

As shown in fig. 7, pilot tone select rule for：The serial number p of the pilot tone of first signal of the M times transmission_M-1=mod (p₁ +(M-1)², K), K is that the maximum of pilot tone sequence number is identical, and terminal passes the first signal, the sequence of pilot tone at the beginning of moment t is to the network equipment Number be 2；Confirmation message of the terminal due to being not received by network equipment transmission, in next cycle retransmit for the first time, The serial number 3 of the pilot tone of rule selection is selected according to pilot tone, the signal retransmitted for the first time is sent using pilot tone corresponding to sequence number 3； Transmission is still unsuccessful, and having carried out second in next cycle is retransmitted, and the serial number of the regular pilot tone selected is selected according to pilot tone 6, second of signal retransmitted is sent using pilot tone corresponding to sequence number 6；Now there is another terminal also to be sent out simultaneously to the network equipment Another signal (being referred to as secondary signal) is sent, the serial number 3 of pilot tone is selected, secondary signal is sent using pilot tone corresponding to sequence number 3.Eventually End the first signal of transmission is still unsuccessful, and having carried out third time in next cycle retransmits, and is led according to what pilot tone selection rule selected The serial number 11 of frequency, the signal of third time re-transmission is sent using pilot tone corresponding to sequence number 11.

The network equipment have received signal in moment t, t+T, t+2T successively.After each signal progress pilot detection of reception, The serial number 2 of the pilot tone for the signal that moment t is received, the serial number pilot tone 3, t+ of the pilot tone for the signal that t+T is received are detected respectively The sequence number of the pilot tone for two signals that 2T is received is respectively pilot tone 6 and 3, but equal decoding failure.

Then, the network equipment receives signal in moment t+3T, after carrying out pilot detection to this signal, detects pilot tone Serial number 11, row decoding, but decoding failure are entered to this signal.

Then the signal that this signal retransmits as first time is set, determines the sequence number of the pilot tone of the first signal of last time reception It should be 11-1=10, but the sequence number of the pilot tone is had no in the signal of last time reception, therefore nonjoinder decoding is handled.

This signal is reset as second of signal retransmitted, determines that last time the first signal of reception should be 11-4+1= 8, but the sequence number of the pilot tone is had no in the signal of last time reception, therefore nonjoinder decoding is handled.

The signal that this signal retransmits for third time is reset, determines that last time the first signal of reception should be 11-9+4= 6, last time should be 11-9+1=3, and upper upper last time should be 11-9=2, then the pilot tone that this signal and last time are received The signal of the serial number 3 for the pilot tone that the signal of serial number 6, upper last time receive and upper upper last time receive the letter of the serial number 2 of pilot tone Decoding number is merged, obtains the data that terminal is sent to the network equipment.

Alternatively, the network equipment is when setting the signal that this signal retransmits as third time, also by this signal and pilot tone The signal of serial number 6 and the signal of serial number 3 of pilot tone merge decoding, by the serial number 6 of this signal and pilot tone The signal of the serial number 2 of signal and pilot tone merges decoding, by the signal and pilot tone of this signal and the serial number 3 of pilot tone The signal of serial number 2 merges decoding.

The data transmission method that the present embodiment provides, by such scheme, terminal can not known by realizing the network equipment Mark in the case of, in failed decoded signal, the more parts of signals decoded not successfully can be merged decoding processing with Data are obtained, and the sequence of the pilot tone of the signal of the present embodiment meets pilot tone selection rule, is merged to more parts of signals Complexity is reduced during decoding processing, improves merging decoding treatment effeciency.

Fig. 8 is the flow chart for the data transmission method that one embodiment of the invention provides, as shown in figure 8, the side of the present embodiment Method can include：

S401, terminal determine to send the sequence number of the pilot tone of the first signal of the M times transmission.

M is the integer more than or equal to 1.

S402, terminal send the M times transmission using pilot tone corresponding to the sequence number according to the sequence number to the network equipment The mark of terminal belonging to first signal and first signal.

S403, the network equipment set first signal as n-th retransmission when failing to first signal interpretation First signal.

S404, the network equipment obtain according to the mark of the terminal from the signal of the failed decoding of the preceding n times reception The signal for taking the Q terminal of the mark that can detect the terminal to send.

1≤Q≤N。

Alternatively, the mark of the terminal-pair terminal can use the coding mode of fixed robust to be modulated, and such as use Code check is 0.1 coded system.Correspondingly, the network equipment can translate the mark of the terminal with high probability.So that N is equal to 3 as an example, if The network equipment is not go out the mark of the terminal from the signal detection of the 2nd reception, and therefore, the network equipment can connect from 3 times Receive failed decoding signal in obtains the 1st time receive and detect the signal corresponding to the mark of the terminal, and 3rd reception and detect the signal corresponding to the mark of the terminal.

The signal that S405, the network equipment are sent according to the described Q times terminal, enters at row decoding to first signal Reason.

In the present embodiment, what the signal corresponding to same terminal iidentification sent for same terminal, hence, it can be determined that above-mentioned The signal that the Q terminal of the mark that can detect the terminal of acquisition is sent is believed for the first of Q reception of the network equipment Number, and the signal sent according to the described Q times terminal, row decoding processing is entered to first signal of n-th retransmission.

Wherein, how the signal sent according to the described Q times terminal, decoding processing is merged to first signal Implementation process may refer to S204 in Fig. 2, or, the specific implementation process in S204 and S205, or, may refer to figure Specific implementation process in 5 in S306, here is omitted.

Alternatively, so that N is equal to 3 as an example, Q is equal to 2, and the network equipment 3 times receives according to the mark of the terminal from described Failed decoding signal in obtain the signal that can detect that 2 times of the mark terminals of the terminal are sent, this 2 ends The first signal that end is sent is the 2nd the first signal sent of the 1st the first signal received of the network equipment or the network equipment, Failed decoding of the rule from the 2nd reception can be selected by pilot tone for the first signal of the 2nd reception of the network equipment Determined in signal, or arbitrarily determine the signal of a transmission from the signal of the failed decoding of the 2nd reception at random；So Afterwards further according to the first signal 3 times received, decoding processing is merged to the first signal of n-th retransmission.

Alternatively, the mark of the terminal also carries transmission instruction；When the M is 1, the transmission, which is designated as just passing, to be referred to Show；When the M is more than 1, the transmission is designated as retransmit.Correspondingly, above-mentioned S403 a kind of possible implementation For：When the transmission is designated as retransmit, first signal of first signal as n-th retransmission is set.Correspondingly, when When transmission is designated as just passing instruction, then terminate, wait receives the first signal next time.

Such as：Randomly selected pilot tone serial number 2 when the first signal is passed at the beginning of terminal to the network equipment, and the mark of terminal Middle transmission is designated as just passing instruction.Terminal to the network equipment retransmit the first signal when randomly selected pilot tone serial number 6, it is and right Transmission is designated as retransmit in the mark of terminal.The network equipment receives the first signal for the first time, and detects the sequence number of pilot tone For 2, and the mark of terminal is decoded out, know that transmission is designated as just passing instruction, but decode the first Signal Fail；Then network is set The first signal of standby second of reception, and the serial number 6 of pilot tone is detected, and the mark of the same terminal is decoded out, know biography It is defeated to be designated as retransmit, then this first signal twice is merged into decoding processing.Alternatively, transmission instruction can also be M occurrence, it is the M times transmission of the first signal to represent this.

Alternatively, a kind of S402 possible implementation is：When the M is more than 1, using common corresponding to the sequence number Yoke pilot tone sends the mark of terminal and first signal of the M times transmission to the network equipment, and conjugated pilot mentioned here is Finger takes conjugation to pilot tone corresponding to the sequence number.Or when M is equal to 1, using normal pilot tone corresponding to the sequence number to network Equipment sends the mark of terminal and first signal of the M times transmission.Correspondingly, above-mentioned S403 a kind of possible realization side Formula is：When the pilot tone of first signal is conjugated pilot, it is the first signal retransmitted to illustrate first signal, is then set First signal is the first signal of n-th retransmission.Alternatively, when the pilot tone of first signal is normal pilot tone, say Bright first signal is the first signal just passed, is then terminated, and wait receives the first signal next time.

Such as：The serial number 2 of randomly selected pilot tone when the first signal is passed at the beginning of terminal to the network equipment, and according to sequence number The mark of the first signal and terminal is sent for 2 normal pilot tone.The pilot tone that terminal selects when retransmitting the first signal to the network equipment Serial number 2, and send according to the conjugated pilot of serial number 2 mark of first signal and terminal.The network equipment connects for the first time The first signal is received, and detects the serial number 2 of pilot tone, and decodes out the mark of terminal, the pilot tone according to the first signal is normal Pilot tone knows first signal just to pass signal, but decodes the first Signal Fail；Then second of reception first of the network equipment Signal, and the serial number 2 of pilot tone is detected, and the mark of the same terminal is decoded out, the pilot tone according to the first signal is common Yoke pilot tone knows first signal to retransmit signal, then this first signal twice is merged into decoding processing.

In addition, in the various embodiments described above, during multiple signals are merged with decoding processing, can be based on Chase merges (chase combining, CC) or increment merges (incremental redundancy, IR), in above two In merging mode, it is necessary to according to the redundant version number (redundancy for merging each signal for decoding processing Version, RV) these signals are merged with decoding processing.Wherein, the redundant version number of signal and the number of retransmissions of the signal Mapping relations be present, either exist with the sequence number of the pilot tone of the signal mapping relations or with the signal number of retransmissions and the letter Number both sequence numbers of pilot tone mapping relations be present and (such as pushed away by the sequence number of the number of retransmissions of the signal and the pilot tone of the signal Export the redundant version number in the signal).

The data transmission method that the present embodiment provides, terminal also send the mark of the terminal when sending signal together, So that the network equipment can also detect that the mark of the terminal in reception signal, the mark of same terminal will can be detected not Successfully decoded signal merges decoding to obtain data.

It should be noted that the various embodiments described above of the present invention be able to can also answer applied in HARQ synchronous transfer For in HARQ asynchronous transmission.
