Wherein, transmitting the corresponding frequency spectrum just passing data of described re-transmission data is the second frequency spectrum；

Described first frequency spectrum is identical or different with described second frequency spectrum.

Described HARQ information carries out the request of data re-transmission for request base station.Described in the present embodiment step Rapid S110 and step S120 do not have certain sequencing；But all occurred before step S130.

The duration of the first appointment time is more than the duration of described second appointment time in the present embodiment, and described the Two appointment times can be a time period in the described first appointment time.Specifically such as the described first appointment time Can be divided into N number of described second appointment time, described N can be integer not less than 1, such as the 2nd, 3 or 4 Deng.

The unlicensed spectrum that in described step S120, determination be can be used within the first appointment time, specifically such as By base station, concrete interval T as every in LAA base station is determined in unlicensed spectrum by carrier wave selection mode M available carrier wave.The duration of described time T was i.e. equal to for the described first appointment time.Described M load Ripple is M the available unlicensed spectrum that can be used within the described first appointment time.

The described second appointment time is a time period in the described first appointment time, when described second specifies In the first interior appointment time, the available unlicensed spectrum determining in the step s 120 have may by Occupy and entering row data communication, it is contemplated that within the described second appointment time, be not used in described base station lead to Letter, therefore available unauthorized by can be used for for the second appointment time in described step S130 of the present embodiment Frequency spectrum is selected a frequency spectrum as the first frequency spectrum sending re-transmission data.Wherein, the described second appointment time Available mandate frequency spectrum included by can be the complete or collected works of unlicensed spectrum available in the described first appointment time or son Collection.But the frequency spectrum beyond available unlicensed spectrum in generally will not including the described first appointment time.

Described first frequency spectrum selected in step s 130 can select an available unlicensed spectrum for any Carrying out retransmitting communication, described first frequency spectrum of selection can be identical or not with the second frequency spectrum for passing at the beginning of data With, it is clear that when using the method described in the present embodiment to carry out data re-transmission, it is not necessary that wait for carrying out data The second frequency spectrum just passing carries out data re-transmission, it is clear that so can reduce when described second frequency spectrum is occupied, The speed of response that described data retransmit, thus improve communication quality and user's user satisfaction.

Embodiment of the method two:

Step S110: receive the HARQ information that terminal sends；

As in figure 2 it is shown, described method also includes:

Step S111: before utilizing described first frequency spectrum to send re-transmission data, under authorizing on frequency spectrum Row control information takies instruction information to the described available unlicensed spectrum of terminal transmission；

The described instruction information that takies is for entering line number to the described base station of terminal instruction within the described second appointment time According to the available unlicensed spectrum sending.

Described taking in instruction information can include for the second finger time will be used for carrying out the unlicensed spectrum of data transmission Identification information.So terminal is after receiving described identification information, it is believed that within the second appointment time The corresponding frequency spectrum of described identification information is will to carry out the available unauthorized of data transmission in the described second appointment time Frequency spectrum.

The described mark taking available unlicensed spectrum in instruction information may additionally include the described first appointment time Information, and mark the interior label information by the available unlicensed spectrum using of described second appointment time, this Sample terminal combines described identification information and described label information, thus can confirm that out the described second appointment time The interior available unlicensed spectrum that will carry out data transmission.Described label information can use bitmap to carry out table Showing, each described frequency spectrum can use 1 data bit to be indicated, and when this data bit is 0 and 1, represents Whether be used within the described second appointment time send data different conditions.If as 1 expression takies This frequency spectrum carries out data transmission within the second appointment time, then be that 0 expression is not take up this frequency spectrum in the second appointment Carry out data transmission in time.

Obviously, when implementing, the described information content taking instruction information and information structure mode have multiple, Be not limited to above-mentioned any one, in a word in the method described in the present embodiment, by sending described to terminal Take instruction information, thus can inform terminal within the second appointment time, it is only necessary to specify the time second In carry out information blind check in available unlicensed spectrum, not be used in each available unlicensed spectrum or the All carry out information blind check in available unlicensed spectrum described in one appointment time, enter such that it is able to reduce terminal Row information blind check amount such that it is able to reduce the power consumption of terminal, extends the stand-by time of terminal.

Embodiment of the method three:

Step S110: receive the HARQ information that terminal sends；

As in figure 2 it is shown, described method also includes:

As it is shown on figure 3, described method also includes:

Step S112: send described available unauthorized frequency to terminal by authorizing the Downlink Control Information on frequency spectrum Spectrum take instruction information before, to described terminal send first instruction information, wherein, described first instruction Information is for indicating the described available unlicensed spectrum within the described first appointment time；

Described first instruction information and the described instruction information that takies are provided commonly for the described base station of described terminal instruction Carry out the available unlicensed spectrum of data transmission within the described second appointment time.

Sending the described first instruction information to terminal in the present embodiment, the first instruction information is used for informing terminal Which the available unlicensed spectrum that can be used for communicating within the first appointment time has, so follow-up All can only need in each described second appointment time in one appointment time to send in the second appointment time of expression To be used for carrying out the label information of data transmission.When thus can reduce each described second appointment Take the information content of instruction information described in interior, thus data interaction amount between base station and terminal will be reduced, from And the energy consumption of terminal can be reduced, extend the standby time of terminal.

Specifically such as, the start time in the first appointment time, covered in described base station by described step S112 All terminals in the cell range that cap-shaped becomes send the described first appointment information, and described first appointment information refers to Understand that available unlicensed spectrum includes frequency spectrum A, frequency spectrum B, frequency spectrum C, frequency spectrum D within the first appointment time And frequency spectrum E.In the start time of the second appointment time each described in step S111, transmission frequency spectrum A, The label information of frequency spectrum B, frequency spectrum C, frequency spectrum D and frequency spectrum E, this label information can be one by 1 The bit map that bit is constituted.Being made up of 5 bits in this bit map, terminal and base station are all given tacit consent to, 1st bit represents the label information whether frequency spectrum A took within the second appointment time；2nd bit table Show the label information whether frequency spectrum B took within the second appointment time；3rd bit represents frequency spectrum C The label information whether taking in two appointment times；4th bit represents frequency spectrum D within the second appointment time The label information whether taking；And the 5th bit represents what whether frequency spectrum E took within the second appointment time Label information.By forming 01 sequence, so base station just can inform that terminal refers to second in this bit map Fix time and interior will be used for carrying out the information of the frequency spectrum of data transmission.If there being 8 in the described first appointment time Two appointment times, then in the described first appointment time, the identification information of available unlicensed spectrum can only send one Secondary, and take instruction information and need to send 8 times, relatively both sent the identification information of frequency spectrum and sent out simultaneously simultaneously Send frequency spectrum the need of occupied label information within the second appointment time, it is clear that the side described in the present embodiment Method, the information content of transmission is less.

Use this combination first indicate information and take instruction information indicate within the second appointment time for Send the available unlicensed spectrum of data, it is clear that can not only inform which terminal arrives within the second appointment time Individual frequency range carries out data blind check and reception up, and the information content also with transmission simultaneously is few, can subtract further The energy consumption of few terminal, extends the standby time of terminal.

Embodiment of the method four:

Present embodiments provide a kind of information processing method, be different from a described upper method implement described in Information processing method, same has the problem that can reduce data transmission delay.

Below in conjunction with above-mentioned any embodiment one specific example of offer:

There is provided a kind of information processing method in the present embodiment, described method includes:

Step S1: base station per interval T, determines the M in unauthorized frequency range by carrier selecting method CC, composition available CC set, namely U1, and this information is notified to all terminals by RRC information. This carrier wave selection cycle T can arrange longer, because which is semi-persistent scheduling, and available 160ms, 320ms, 640ms etc., and its cycle T and M can configure by base station.Described CC herein is unauthorized Frequency spectrum, it may include above-mentioned first frequency spectrum and the second frequency spectrum.Described U1 is can use within the first appointment time The set of unlicensed spectrum.Described T can be the above-mentioned first appointment time.Described RRC can be Radio Resource Control information.Described base station can be LAA base station.Carrier wave in described U1 can be collectively referred to as CC1.

Step S2: terminal reads rrc message, and preserves the configuration information of CC1.

Step S3: base station, when downlink transfer, is used in the physical downlink control channel PDCCH of main plot Bit map bit-map prepares M bit in advance for indicating in U1, whether CC1 can use.Now, institute The bit map stated is equivalent to take instruction information in above-described embodiment.

Step S4: each CC in U1 is inquired about by base station, determines the seizure condition of each CC.

Case 3:

Have its corresponding retransmission process number, and each CC in U1 corresponding to each CC in set U1 One_to_one corresponding 0 is to the sequence number of M-1, and when downlink transfer, PDCCH not only needs to indicate below Retransmit the re-transmission version of data, in addition it is also necessary to instruction retransmits version is corresponding just passes which CC in U1 Initial transmission in which process.User terminal can be according to this information, by Physical Downlink Shared Channel The re-transmission data of PDSCH and re-transmission version are given to corresponding CC, and merge decoding.

Step S7: base station carries out downlink data transmission according to process above.

Step S8: first terminal detects the PDCCH in Pcell, it is thus achieved that the group of CC shared by real base station Close U2, and in corresponding frequency range, carry out PDCCH blind check, detect whether to issue the data of oneself, It and corresponding data is re-transmission or new data etc., and is received locating to PDSCH according to the instruction of PDCCH Reason.

Step S9: the ACK/NACK feedback corresponding to the PDSCH in unauthorized frequency range uses original CA Processing method, be i.e. transmitted by the ascending control channel PUCCH of Pcell.

Step S10: base station is according to the feedback on PUCCH, to the number transmitting in unauthorized frequency range before According to carrying out retransmitting or new biography.Herein, new biography is the first biography carrying out next data.
