Above-mentioned process can be applied in unauthorized frequency range carry out data transmission, and can also be applied to carry out in authorized spectrum band
Data transmission, or can also be applied on the frequency range of other rule definition carry out data transmission.
Preferably, above-mentioned process is applied to carry out data transmission in unauthorized frequency range by the embodiment of the present invention, such feelings
Under condition, after the network equipment can be made to access channel, the transmission sequence that advanced processing obtains is sent.
Unlicensed spectrum does not plan specific application system, can for various wireless communication system for example bluetooth, Wi-Fi,
LTE etc. is shared, uses shared unlicensed spectrum resource between multiple systems by way of preempting resources.3GPP regulation, non-
When disposing LTE system in authorized spectrum band, unauthorized frequency range as secondary carrier by the main carrier back work on authorized frequency bands, this
Technology is known as LAA (Licensed-Assisted Access, authorization carrier frequency section adjuvant grafting enter).To guarantee LTE in unauthorized frequency range
With other wireless fair co-existences such as Wi-Fi, extensive approval has been obtained using LBT (listen Before Talk) technology.
In order to provide a flexible fair adaptive channel access mechanism, etsi standard is required unauthorized
5150-5350MHz and 5470-5725MHz frequency range use LBT technology.LBT process is similar to the CSMA/CA (carrier of WiFi
Sense multiple access with collision avoidance, the Carrier Sense Multiple of conflict avoidance) mechanism, often
CCA (Clear Channel Assessment) detection is carried out before a equipment utilization channel.Etsi standard is by unauthorized frequency
The device class of section is FBE (Frame Based Equipment, the equipment based on frame) and LBE (Load Based
Equipment, the equipment based on load), two different Channel Access Mechanisms are respectively corresponded, as shown in figs. 5 and 6.

10ms.Idling cycle is at least the 5% of Channel holding time.Within the CCA time of idling cycle tail portion, equipment executes new
CCA detection carries out channel access again.Channel holding time adds idling cycle to be that a fixed value is known as in FBE mechanism
frame period。
As shown in fig. 6, LBE Channel Access Mechanism, channel transmission time and starting point are all variable.Before accessing channel
It is extended CCA detection, that is, generates a random factor N, until idle time of channel reaches N times of CCA time, is just connect
Enter channel, initiates data transmission, and maximum Channel holding time is 13ms.
It is needed according to the LTE system of LTE system and unauthorized frequency range in the requirement authorized spectrum band of current 3GPP in the time
Upper alignment.It to the LTE system in unauthorized frequency range, is influenced by factors such as LBT contention access, radio frequency times, data pass
Defeated start time may be in any position in a subframe, that is, what is sent is imperfect subframe in a time domain.
As previously mentioned, the embodiment of the present invention is preferably applied to the scene carried out data transmission using unauthorized frequency range.
Under the scene, it is based on process shown in FIG. 1, before step 101, the network equipment can carry out channel by above-mentioned competitive way
Access.In a step 101, network equipment acquisition should be in one on the carrier wave (than first carrier as the aforementioned) of authorized spectrum band
Data to be transmitted in subframe；In a step 102, the data to be transmitted that the network equipment will acquire is handled to obtain N number of hair
Send sequence；In step 103, from the first subframe (than the first subframe as the aforementioned) of the network equipment in unauthorized frequency range
A OFDM symbol starts until n-th OFDM symbol successively to transmit N number of A sent in sequence to n-th transmission sequence
Column, in another subframe in the unauthorized frequency range (than the second subframe as the aforementioned) since first OFDM symbol to the
N number of first to the A-1 transmission sequence sent in sequence is successively transmitted until A-1 OFDM symbol.
It can be seen that, on the one hand, the data in a subframe in authorized spectrum band are used unauthorized frequency range by the network equipment
On multiple subframes transmit, and the 2nd in the first subframe at least in unauthorized frequency range OFDM symbol starts to transmit, be
The network equipment and terminal, which carry out data transmission being prepared operation, leaves the time；On the other hand, the network equipment is in unauthorized frequency
The OFDM symbol quantity that section is used to carry out data transmission is fixed, and is in regularity distribution, is connect so that terminal be allow to determine
The position of data is received, to guarantee that terminal is able to carry out data receiver.
Further, on the basis of various embodiments of the present invention, if only preceding L OFDM symbol is used in first subframe
In downlink transfer, and A≤L < N, then N number of L+1 sent in sequence is sent sequence to n-th and set by the network equipment
For sky.Alternatively, then the network is set if only preceding K OFDM symbol is used for downlink transfer, and K≤A-1 in second subframe
Standby K+1 to the A-1 transmission sequence by N number of transmission sequence is set to sky.Above-mentioned two situations also may be used in combination.
