It should be understood that, in the TDD of traditional LTE, subframe 1 and subframe 6 are respectively the special subframe of TDD, the special subframe 1 and special subframe 6 separately include DwPTS, protection interval (Guard Period, referred to as " GP ") and uplink pilot time slot (Uplink Pilot Time Slot, referred to as " UpPTS ") three parts, wherein UpPTS and GP is not used in transmission data, only DwPTS is used for transmission data and control information etc., so in extension physical mixed automatic re-transmission indicating channel (Physical Hybrid ARQ Indicator Channel, referred to as " PHICH ") under length, in DwPTS, PHI is sent using 2 symbols CH；Under normal PHICH length, in DwPTS, PHICH is sent using 1 symbol.

Therefore, as shown in figure 3, base station can design the last one imperfect subframe using the configuration of DwPTS, but how to indicate that the DwPTS configuring condition of the last one imperfect subframe is a problem to be solved.

Specifically, DwPTS configures signed number to indicate to be respectively as follows: 3,6,9,10,11,12 symbols, and base station can be configured to one of 6 kinds of numbers of symbols with instruction information instruction DwPTS configuration, i.e. instruction DwPTS.

It it should be understood that base station can indicate that the DwPTS of the last one imperfect subframe is configured by indicating information, after UE receives instruction information, can know that its DwPTS is configured, not need UE by detection and obtain the DwPTS configuration that base station is sent, it is thus possible to save the power consumption of UE.

S120, base station send instruction information to UE by reference to subframe.

In S120, base station can send instruction information to UE by reference to subframe, indicate the DwPTS configuration of the last one imperfect subframe, i.e. the DwPTS configuration of instruction information instruction UE.

It should be understood that this can be the last one imperfect subframe of unauthorized carrier wave with reference to subframe, can be The complete subframe of any one of unauthorized carrier wave can also be any one subframe of authorization carrier wave.

Therefore, a kind of method of transmission data of the embodiment of the present invention, in LAA-LTE system, base station indicates that the DwPTS of the last one imperfect subframe is configured by reference to subframe, in this way, UE can determine that DwPTS is configured according to instruction information, do not need to determine DwPTS configuration by detecting again, can save the power consumption of UE.

It should be understood that using synchronous hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, referred to as " HARQ ") mode, there is uplink the set time to require for initial transmission and re-transmission for traditional LTE system.PHICH is used for data response HARQ correct (ACK) or HARQ error (NACK) to Physical Uplink Shared Channel (Physical Uplink Shared Channel, referred to as " PUSCH ") transmission.

For example, UE can detect corresponding PHICH in subframe n+4 if UE sends PUSCH in subframe n, if receiving is NACK, retransmitting data can transmit again in subframe n+8.And for LAA carrier wave, due to LAA-LTE UE cannot busy channel always, so discontinuous transmission causes the re-transmission of HARQ to be interrupted, e-NodeB retransmits data packet after UE can only be waited to seize channel again, and the waiting time may be very long, causes data delay.

Therefore, it is directed to for LAA, uplink uses asynchronous HARQ operation, PHICH is not needed then, thus in an embodiment of the present invention, instruction information can be sent by the PHICH in the DwPTS of the last one imperfect subframe, which indicates the DwPTS configuration of the last one imperfect subframe of base station.

It should be understood that being directed to for LAA, in the case where extending PHICH length, 2 symbols can be used in the DwPTS of the last one imperfect subframe to send PHICH；Under normal PHICH length, 1 symbol can be used in the DwPTS of the last one imperfect subframe to send PHICH, the present invention does not do any restrictions to this.

It should be understood that in third generation partner program (3rd Generation Partnership Project, referred to as " 3GPP ") related DwPTS concrete configuration situation such as the following table 1 of standard:

Table 1

It should be understood that in LAA, usually using downlink general cyclic prefix (Cyclic Prefix, referred to as " CP "), wherein T_sFor using the inverse of rate, each subframe can have 14 orthogonal frequency division multiplexis (Orthogonal Frequency Division Multiplexing, referred to as " OFDM ") symbol, each sub-frame configuration is different, then OFDM symbol number shared by DwPTS, GP, UpPTS is different, wherein, DwPTS may include 3-12 symbol.

Therefore, it can be by indicating the configuring condition of the DwPTS of the last one imperfect subframe in the PHICH in the DwPTS of the last one imperfect subframe or by increasing new bit in the PDCCH in the DwPTS of the last one imperfect subframe with base station, as table 1 can be seen that, DwPTS has 6 kinds of different configurations, and specific signed number mesh indicates to be respectively as follows: 3,6,9,10,11,12 A symbol.

Therefore, it is possible to increase by 3 bits in the PHICH or PDCCH in the DwPTS of the last one imperfect subframe to indicate the configuration of DwPTS, as shown in table 2 below:

Table 2

DwPTS configuration	Index	Specific symbolic number
Configuration 1	000	3 OFDM symbols
Configuration 2	001	6 OFDM symbols
Configuration 3	010	9 OFDM symbols
Configuration 4	011	10 OFDM symbols
Configuration 5	100	11 OFDM symbols
Configuration 6	101	12 OFDM symbols

It should be understood that the instruction information can configure corresponding index (index) for DwPTS, index indicates the DwPTS configuration of the last one imperfect subframe of unauthorized carrier wave.As shown in table 2, it can indicate that DwPTS's is configured to 3 OFDM symbols with index of reference " 000 ", it can indicate that DwPTS's is configured to 6 OFDM symbols with index of reference " 001 ", it can indicate that DwPTS's is configured to 9 OFDM symbols with index of reference " 010 ", it can indicate that DwPTS's is configured to 10 OFDM symbols with index of reference " 011 ", it can indicate that DwPTS's is configured to 11 OFDM symbols with index of reference " 100 ", can indicate that DwPTS's is configured to 12 OFDM symbols with index of reference " 101 ".

It therefore, can be by indexing the different configuring condition for indicating DwPTS or different symbolic numbers, to obtain the configuring condition of the DwPTS of the last one imperfect subframe of base station.

It should be understood that, 3 bits or any several bits can be increased in PHICH or PDCCH in the DwPTS of the last one imperfect subframe of unauthorized carrier wave to indicate the configuration of DwPTS, such as 4 bit or 5 bits, the configuration of DwPTS either is indicated by increasing other information in PHICH or PDCCH, and the present invention is without limitation.

Optionally, base station can send instruction information to UE by any one complete subframe of unauthorized carrier wave.

Specifically, base station can send instruction information to UE by the PHICH or PDCCH of any one complete subframe of unauthorized carrier wave.
