Step S111: before sending re-transmission data using first frequency spectrum, the downlink passed through on authorization frequency spectrum is controlled Information can indicate information with the occupancy of unlicensed spectrum to described in terminal transmission；

The occupancy instruction information is used to indicate that the base station carries out data hair within second specified time to terminal The available unlicensed spectrum sent.

The instruction information that occupies may include the mark that will be used to carry out the unlicensed spectrum of data transmission in the second finger time Know information.Terminal is after receiving the identification information in this way, it is believed that the identification information pair within the second specified time The frequency spectrum answered is the available unlicensed spectrum that data transmission will be carried out in second specified time.

The instruction information that occupies may additionally include the identification information that unlicensed spectrum can be used in first specified time, And by the mark information of the available unlicensed spectrum used in label second specified time, such terminal is in conjunction with the mark Know information and the mark information, thus can confirm that out that will to will do it can be used for data transmission in second specified time non- Authorize frequency spectrum.The mark information can be indicated using bitmap, each described frequency spectrum can be used 1 data bit and carry out It indicates, when which is 0 and 1, the different conditions that whether be used to send data within second specified time of expression. Such as indicate that occupy the frequency spectrum carries out data transmission within the second specified time, then indicates to be not take up the frequency spectrum second for 0 if 1 Data transmission is carried out in specified time.

Obviously in specific implementation, there are many information content for occupying instruction information and information constituted modes, not office It is limited to any one of the above, in a word in the method described in the present embodiment, indicates information by sending the occupancy to terminal, this Sample can inform terminal within the second specified time, it is only necessary to the enterprising row information of unlicensed spectrum can be used within the second specified time Blind examination, without can be used at each in available unlicensed spectrum described in unlicensed spectrum or in the first specified time Information blind examination is carried out, extends terminal so as to reduce terminal progress information blind examination amount so as to reduce the power consumption of terminal Stand-by time.

Embodiment of the method three:

Step S110: the HARQ information that terminal is sent is received；

As shown in Fig. 2, the method also includes:

As shown in figure 3, the method also includes:

Step S112: by authorization frequency spectrum on Downlink Control Information to terminal send described in can accounting for unlicensed spectrum Before instruction information, Xiang Suoshu terminal sends the first instruction information, wherein the first instruction information is used to indicate described Described in first specified time uses unlicensed spectrum；

The first instruction information and occupancy instruction information are provided commonly for indicating the base station in institute to the terminal State the available unlicensed spectrum that data transmission is carried out in the second specified time.

The first instruction information is sent to terminal in the present embodiment, the first instruction information is for informing terminal first Which the available unlicensed spectrum that can be used for being communicated in specified time has, in this way subsequent every within the first specified time It can only need to send the label for indicating will to be used to carry out data transmission in the second specified time in one second specified time Information.The information content for occupying instruction information in each described second specified time can be thus reduced, thus Data interaction amount between reduction base station and terminal is extended into the standby time of terminal so as to reduce the energy consumption of terminal.

Specifically such as, it at the beginning of the first specified time, to be formed by the step S112 to being covered in the base station Cell range in all terminals send first specify information, first specify information is specified when first is specified Interior can include frequency spectrum A, frequency spectrum B, frequency spectrum C, frequency spectrum D and frequency spectrum E with unlicensed spectrum.In each institute in step S111 At the beginning of stating for the second specified time, the mark information of frequency spectrum A, frequency spectrum B, frequency spectrum C, frequency spectrum D and frequency spectrum E, the label are sent Information can be a bit map being made of 1 bit.It is made of in the bit map 5 bits, terminal and base station Default, the 1st bit indicates the mark information whether frequency spectrum A occupies within the second specified time；2nd bit indicates frequency spectrum The mark information whether B occupies within the second specified time；3rd bit indicates whether frequency spectrum C accounts within the second specified time Mark information；4th bit indicates the mark information whether frequency spectrum D occupies within the second specified time；And the 5th bit Indicate the mark information whether frequency spectrum E occupies within the second specified time.Base station can pass through in the bit map in this way It forms 01 sequence and informs that terminal will be used to carry out the information of the frequency spectrum of data transmission within the second specified time.If described first refers to There are 8 the second specified times in fixing time, then can use the identification information of unlicensed spectrum can be only in first specified time It sends primary, and occupies instruction information and need to send 8 times, the relatively simultaneous identification information for both having sent frequency spectrum or while sending frequency spectrum Whether during second specified time occupied mark information is needed, it is clear that method described in the present embodiment, the information content of transmission It is less.

It is indicated using this combination first instruction information and occupancy instruction information within the second specified time for sending The available unlicensed spectrum of data, it is clear that can not only inform terminal within the second specified time to going to carry out in which frequency range Data blind examination and reception, at the same also have send information content it is few, the energy consumption of terminal can be further reduced, extend terminal to Machine duration.
