Embodiment two

Fig. 3 is the implementation process schematic diagram two of ascending transmission method of the embodiment of the present invention；As shown in figure 3, the method is answered For terminal side；The described method includes:

Step 301: sending uplink scheduling request message；

Step 302: receiving the uplink scheduling authorization signaling determined according to the uplink scheduling request message；Wherein, institute State the different subframes that uplink scheduling authorization signaling indicates N number of different moments；The N is the positive integer more than or equal to 2.

Here, terminal sends uplink scheduling request message to base station, and the base station receives the uplink scheduling request message, Uplink scheduling authorization signaling is determined according to the uplink scheduling request message, is indicated in the uplink scheduling authorization signaling multiple Uplink scheduling chance, and the uplink scheduling authorization signaling (UL Grant) is sent to terminal, the terminal receives on described Row scheduling authorization signaling；The terminal detects the corresponding frequency band of uplink scheduling chance according to the uplink scheduling authorization signaling, and Can judgement send the corresponding uplink service of the uplink scheduling request message on the corresponding frequency band of the uplink scheduling chance Data；Wherein, the uplink scheduling chance refers to the specific sub-frame of particular moment, therefore, the uplink scheduling authorization signaling Indicate that different uplink scheduling chances refers to that the uplink scheduling authorization signaling indicates the different subframes at multiple and different moment.

In above scheme, the method also includes:

Judge the frequency band ginseng of the corresponding frequency band of the first subframe at the first moment in the different subframes of N number of different moments Whether numerical value is less than preset threshold；

If so, being sent out on the corresponding frequency band of the first subframe at the first moment in the different subframes of N number of different moments Send the uplink scheduling request message corresponding uplink business data.

Here, terminal successively determines the frequency of the different subframes of N number of different moments of the uplink scheduling authorization signaling instruction Section, successively detects the frequency range of the different subframes of N number of different moments, and successively judges difference of N number of different moments Whether the frequency band parameter values of the frequency range of frame are more than preset threshold, if so, explanation be more than preset threshold frequency band parameter values to it is corresponding when The subframe at quarter is busy, i.e., channel busy at this time, cannot subframe upload at the time of the frequency band parameter values for being more than preset threshold correspond to Therefore the corresponding uplink business data of the defeated uplink scheduling request message continues to judge the corresponding frequency of the subframe of subsequent time Whether the frequency band parameter values of band are more than preset threshold；

Otherwise, illustrate that the frequency band parameter values more than preset threshold correspond to the subframe spare time at moment, i.e., channel at this time is not busy, can Be more than preset threshold frequency band parameter values correspond at the time of subframe on transmit the uplink scheduling request message it is corresponding on Row business datum；Wherein, the frequency band parameters can make an uproar parameter or other parameters for the bottom on frequency band.

Specifically, if terminal for the first time detection N number of different moments different subframes in the first moment first When the corresponding frequency band of subframe is busy to carry out data transmission, i.e., when the channel busy of the first detection can not carry out data transmission, then eventually End carries out second and detects, that is, the second subframe for detecting the second moment in the different subframes of N number of different moments is corresponding Frequency band, if the channel busy of the second detection can not still carry out data transmission, terminal carries out third time detection, i.e., described in detection The corresponding frequency band of third subframe at the third moment in the different subframes of N number of different moments, and so on, until terminal carries out the The corresponding frequency band idle of X subframe at the X moment in the different subframes of N number of different moments is determined in X detection, described The uplink scheduling request message is transmitted on the corresponding frequency band of X subframe at the X moment in the different subframes of N number of different moments Until corresponding uplink business data；Wherein, the X is the positive integer for being less than or equal to N more than or equal to 1.
