Specifically, embodiments of the invention provide a kind of method for transmitting data, shown in reference picture 2, comprise the following steps：

101st, the first equipment is to before the second equipment transmission data, it is determined that transmission pattern.

The pattern of k sub-channels is included in the transmission pattern, the free timeslot of at least two subchannels is not overlapping in any identical moment k sub-channels, k is the integer not less than 2.It should be understood that subchannel includes physical sub-channels and/or logical sub-channel；Its sub-channels is divided in frequency domain according to frequency range, and transmission pattern includes the positional information of free timeslot in the positional information and at least two subchannel of the time slot of transmission data at least two subchannel；Transmitting pattern is used for the resource for indicating that the time slot and free timeslot of transmission data take.In a communications system, the occupancy for channel resource is generally divided according to the unit time slot of predetermined number, and the time slot of transmission data is one or continuous multiple unit time slots, free time Time slot is one or continuous multiple unit time slots.

102nd, first equipment transmits the data according to the transmission pattern to second equipment.

First equipment sends data by least two subchannel according to the transmission pattern to the second equipment；Specifically, the first equipment sends data in each subchannel using LBT working method to the second equipment.First equipment sends data using LBE or FBE working method by least two subchannel to the second equipment, is not specifically limited here.And when subchannel is physical sub-channels, the first equipment needs to send data using independent wave filter in each physical sub-channels.

In such scheme the first equipment by the transmission pattern of determination to the second equipment transmission data, so that the second equipment detects the data that the first equipment is transmitted by the transmission pattern, due to the pattern for the k sub-channels that the transmission pattern is included, and the free timeslot of at least two subchannels is not overlapping in any identical moment k sub-channels, therefore other equipment can not detect available free timeslot in the corresponding whole bandwidth of transmission pattern, therefore other equipment can not seize channel resource by way of detecting idle channel resources, so as to realize LTE-U nodes exclusive channel resource transmission data within a period of time.

It should be understood that the bandwidth that can be configured in k sub-channels per sub-channels is respectively less than the bandwidth for any channel that other equipment (for example, the 4th equipment) is used；And/or the free timeslot total bandwidth (on frequency domain) of the phase that includes of the continuous subchannel of frequency in the same time is less than the bandwidth for any channel that other equipment (for example, the 4th equipment) is used.Exemplary, shown in reference picture 1, when the 4th equipment is the AP in Wi-Fi systems, the bandwidth of the channel that the 4th equipment is used usually 20MHz can now configure the bandwidth respectively less than 20MHz per sub-channels in k sub-channels；And/or the free timeslot total bandwidth (frequency domain) of the phase that includes of the continuous subchannel of frequency in the same time is less than 20MHz, and then the 4th equipment is avoided to seize the channel resource of the subchannel for meeting bandwidth requirement.

Embodiments of the invention provide a kind of method for transmitting data, shown in reference picture 3, comprise the following steps：

201st, the second equipment is before the data of the first equipment transmission are detected, it is determined that transmission pattern.

The pattern of k sub-channels is included in the transmission pattern, at any identical moment k The free timeslot of at least two subchannels is not overlapping in subchannel, and k is the integer not less than 2.It should be understood that subchannel includes physical sub-channels and/or logical sub-channel；Its sub-channels is divided in frequency domain according to frequency range, and transmission pattern includes the positional information of free timeslot in the positional information and at least two subchannel of the time slot of transmission data at least two subchannel；Transmitting pattern is used for the resource for indicating that the time slot and free timeslot of transmission data take.In a communications system, the occupancy for channel resource is generally divided according to the unit time slot of predetermined number, and the time slot of transmission data is one or continuous multiple unit time slots, and free timeslot is one or continuous multiple unit time slots.

202nd, second equipment detects the data that first equipment is transmitted according to the transmission pattern.

The second equipment detects the data that the first equipment is transmitted by the transmission pattern of determination in such scheme, due to the pattern for the k sub-channels that the transmission pattern is included, and the free timeslot of at least two subchannels is not overlapping in any identical moment k sub-channels, therefore other equipment can not detect available free timeslot in the corresponding whole bandwidth of transmission pattern, therefore other equipment can not seize channel resource by way of detecting idle channel resources, so as to realize LTE-U nodes exclusive channel resource transmission data within a period of time.

It should be understood that the bandwidth that can be configured in k sub-channels per sub-channels is respectively less than the bandwidth for any channel that other equipment (for example, the 4th equipment) is used；And/or the free timeslot total bandwidth (frequency domain) of the phase that includes of the continuous subchannel of frequency in the same time is less than the bandwidth for any channel that other equipment (for example, the 4th equipment) is used.Exemplary, shown in reference picture 1, when the 4th equipment is the AP in Wi-Fi systems, the bandwidth of the channel that the 4th equipment is used usually 20MHz can now configure the bandwidth respectively less than 20MHz per sub-channels in k sub-channels；And/or the free timeslot total bandwidth (frequency domain) of the phase that includes of the continuous subchannel of frequency in the same time is less than 20MHz, and then the 4th equipment is avoided to seize the channel resource of the subchannel for meeting bandwidth requirement.

Below, first equipment is used as using the eNB in LTE-U systems, 4th equipment is used as using the AP nodes in Wi-Fi systems, the specific transmission pattern with reference to shown in Figure 4 and 5, by taking a width of 20MHz of the band that the first equipment is used as an example, includes two logical sub-channels in the eNB transmission patterns used, wherein each logical sub-channel is 10MHz bandwidth, shown in reference picture 4, data frame length 10ms, totally 20 time slots are (English：Slot), comprising 100 moneys Source block (English：Resource Block, referred to as：RB).Working method according to FBE provides that free timeslot length is at least 5% principle of the slot length of transmission data, takes 19 slot to be used as the time slot of transmission data, and 1 slot is used as free timeslot.Under this transmission pattern, 1 10MHz bandwidth (including 50 RB) of 20MHz bandwidth can be set to the 1st logical sub-channel, another 10MHz bandwidth (including 50 RB) is set to the 2nd logical sub-channel, and the free timeslot of this 2 logical sub-channels is not overlapping.For example, FBE working method provides that free timeslot length is at least the 5% of the slot length of transmission data, if 2 logical sub-channels take the time slot of the transmission data of identical duration, wherein transmit the time slot of data when a length of M milliseconds (ms).By taking free timeslot length 5% for the slot length of transmission data as an example, it is late N milliseconds (ms) that 2nd logical sub-channel only needs to than the 1st logical sub-channel transmission time, N values are [0.05*M, M], you can so that the free timeslot of this 2 continuous logical sub-channels in frequency is not overlapping identical at the time of.Transmission pattern that can certainly be as shown in Figure 5 sets the time slot that data are transmitted in two sub-channels.In addition each logical sub-channel is a width of 20MHz of band for the channel that the AP nodes in 10MHZ bandwidth, Wi-Fi systems are used, therefore, when AP nodes detect channel using CCA, is always able to detect that channel is occupied, causes AP nodes to access；And the transmission pattern of LTE-U systems known to the eNB in other LTE-U systems, when detecting the free timeslot of any logical sub-channel by CCA, can smoothly it access；Certain above-mentioned example is only illustrated by taking free timeslot length 5% for the slot length of transmission data as an example, and other ratios can also be realized and are not limited here.

Transmission pattern shown in reference picture 7, by taking a width of 20MHz of the band that the first equipment is used as an example, include two physical sub-channels in the eNB bandwidth used, under this transmission pattern, the physical channel of 20MHz bandwidth can be divided into 2 10MHz independent physical sub-channels, now, the first equipment sends signal in corresponding physical sub-channels respectively using 2 10MHz wave filter, and the free timeslot of this 2 continuous physical sub-channels in frequency is not overlapping identical at the time of；It is the transmission data moment of 2 physical sub-channels in this scheme, similar with the transmission data moment in the embodiment of above-mentioned 2 logical sub-channels of use.

Certainly at least two subchannels set in the first bandwidth can be discharged after LTE-U eNB data are sent completely；Now the channel resource of at least two subchannels is idle condition, then AP nodes now in Wi-Fi systems detect the channel resource free time according to LBE working method, can smoothly access channel, and send data.Optionally, above-described embodiment is only that, using the AP nodes in Wi-Fi systems as the 4th equipment, eNB in LTE-U systems exemplified by the first equipment as illustrating；Certain 4th equipment can also be to provide the user equipment of the AP node serves in Wi-Fi systems, and when the user equipment of the eNB services in LTE-U systems is as the first equipment, data can also be transmitted with reference to the above method, are not being repeated herein.
