Specific embodiment
Below with reference to accompanying drawing and in conjunction with the embodiments describing the present invention in detail.It should be noted that in the feelings not conflicted
Under condition, the feature in embodiment and embodiment in the application can be mutually combined.
It should be noted that description and claims of this specification and the term " first " in above-mentioned accompanying drawing, " second "
Etc. being for distinguishing similar object, without for describing specific order or precedence.
A kind of data processing method is provided in the present embodiment, and Fig. 1 is data processing method according to embodiments of the present invention
Flow chart one, as shown in figure 1, the flow process comprises the steps：
Whether step S102, carry presupposed information in identification of base stations data to be dispatched, and wherein, presupposed information includes following
At least one：Control information, the reference information for decoding other data；
Step S104, in the case of carrying presupposed information in data to be dispatched are recognized, base station arranges data to be dispatched
Number of retransmissions；
Step S106, base station retransmit data to be dispatched on continuous descending sub frame according to number of retransmissions.
By above-mentioned steps, in identification of base stations data to be dispatched, whether presupposed information is carried, for carrying treating for presupposed information
Scheduling data arrange number of retransmissions, and retransmit data to be dispatched on continuous descending sub frame according to number of retransmissions, exhale in group
Shared carrying does not have up carrying, it is impossible to whether information is properly received in the case of feeding back, is user equipment automatically
Retransmission information.It can be seen that, using above-mentioned steps, in solving correlation technique, group exhales shared carrying ensure transmission information
The problem of accuracy, improves the accuracy that group exhales transmission information in shared carrying.
Alternatively, in the shared information for carrying to user equipment and sending is exhaled in base station by group, some information are relatively more
Important, for example：Control information, the reference information for decoding other data, cannot be correctly decoded in above- mentioned information
In the case of, will cause that order cannot be executed correctly or related data cannot be correctly decoded, so as to have impact on system
Stability, therefore, it is in order to solve the above problems, in above-mentioned steps S102, pre- in identification of base stations data to be dispatched
If information includes but is not limited at least one of：Control information, the reference information for decoding other data.
Alternatively, in the transmitting procedure of video data, key frame is the reference information for decoding intermediate frame, above-mentioned
In step S102, key frame can be above-mentioned presupposed information by identification of base stations, and for carrying the number to be dispatched of key frame
Retransmission process is carried out according to number of retransmissions is arranged, that improves key frame information is decoded into power, so as to ensure middle frame information
It is decoded into power.
Alternatively, in above-mentioned steps S104, base station can arrange the re-transmission of data to be dispatched according at least one of
Number of times：The modulation demodulation system of data to be dispatched, channel quality, signal intensity, wherein, the modulatedemodulate of data to be dispatched
The channel encoding rate of tune mode is higher, then setting number of retransmissions is bigger, and the channel quality of transmission data is poorer, then arrange weight
Biography number of times is bigger, and signal intensity is lower, then arrange number of retransmissions bigger.By said method, set according to different conditions
Different number of retransmissions are put, while the accuracy of information transfer is improved, it is also possible to save resources.

Number of times, for example：Base station determines the modulation demodulation system of data to be dispatched；Base station is arranged and is retransmitted according to modulation demodulation system
Number of times, wherein, the channel encoding rate of modulation demodulation system is higher, then arrange number of retransmissions bigger.Modulation demodulation system
Channel encoding rate is higher, and user equipment difficulty during decoding is bigger, and error rate is also higher, is channel encoding rate
Higher modulation demodulation system arranges larger number of retransmissions, and that can improve user equipment is decoded into power, so as to improve
The accuracy of information transfer.
Alternatively, group exhales the shared modulation demodulation system commonly used that carries to include QPSK, 16QAM and 64QAM etc., its
In, the channel encoding rate of these three debugging demodulation modes increases successively, in order to ensure that these three modulation demodulation systems can reach
To certain information transfer accuracy, base station is that the number of retransmissions that these three debugging demodulation modes are arranged becomes big successively, for example：
In above-mentioned steps S104, arranging number of retransmissions according to the modulation demodulation system of data to be dispatched includes at least one of：
Base station determines that the modulation demodulation system of data to be dispatched is QPSK, then it is the first preset value to arrange number of retransmissions；Base station is true
The modulation demodulation system of data surely to be dispatched is 16QAM, then it is the second preset value, wherein, second to arrange number of retransmissions
Preset value is more than the first preset value；Base station determines that the modulation demodulation system of data to be dispatched is 64QAM, then arrange and retransmit
Number of times is the 3rd preset value, and wherein, the 3rd preset value is more than the second preset value.
Alternatively, after above-mentioned steps S102, in the case of not carrying presupposed information in data to be dispatched are recognized,
In order to reduce the waste of resource, more rational Resources allocation, base station can be directly using data to be dispatched as new biography data
It is transmitted, without being retransmitted.
Alternatively, in above-mentioned steps S106, the mark of the presupposed information in data to be dispatched can also be set to by base station
Preset value, preset value is for indicating to carry presupposed information in data to be dispatched.By above-mentioned steps, it is possible to use family sets
It is standby to identify whether to be set to preset value judges whether carry presupposed information in data to be dispatched by identification presupposed information.
A kind of data processing method is additionally provided in the present embodiment, and Fig. 2 is data processing side according to embodiments of the present invention
The flowchart 2 of method, as shown in Fig. 2 the flow process comprises the steps：
Step S202, user equipment receive many parts of numbers to be dispatched for carrying presupposed information from continuous multiple descending sub frames
According to wherein, presupposed information includes at least one of：Control information, the reference information for decoding other data；
Step S204, user equipment merge demodulation to many parts of data to be dispatched.
By above-mentioned steps, user equipment receives many parts of data to be dispatched for carrying presupposed information, and many parts are waited to adjust
Degrees of data merges demodulation, and improve presupposed information is decoded into power, so as to also improve the success rate of information transfer.
It can be seen that, using above-mentioned steps, in solving correlation technique, group exhales asking for the shared accuracy for carrying and cannot ensureing transmission information
Topic, improves the accuracy that group exhales transmission information in shared carrying.
Alternatively, in above-mentioned steps S202, reference information includes：Key frame.User equipment can receive many parts
The data to be dispatched of key frame are carried, and many parts are carried with the data to be dispatched of key frame and merge demodulation, improved
Key frame information is decoded into power, is decoded into power so as to ensure that middle frame information.
