Show for FBE, there is fixing transmission frame-form, Channel holding time and idle period constitute the fixing frame period,
Phase carries out CCA detection to equipment at one's leisure, is idle when channel is detected, then can carry out data transmission immediately, no
Then, the idle period in the next fixing frame period carries out CCA detection again.For European FBE, during channel occupancy
Between for 1ms to 10ms, idle period is at least the 5% of Channel holding time.CCA detection duration is at least
20 μ s, CCA detection can be based on energy measuring it is also possible to be based on signal detection.
Fig. 6 is the LBT schematic diagram of mechanism of the equipment LBE according to the preferred embodiment of the present invention based on load, such as Fig. 6

Detection, if after carrying out CCA detection, when finding channel for the free time, then can carry out data transmission, data immediately
The maximum time that transmission can take is (13/32) × q ms, and wherein q={ 4,5,6 ... 31,32 } is configurable；Otherwise, such as
Really find that channel is busy, enter extension CCA (eCCA) detection period, that is, the CCA of X time to be carried out detects,
The value of X is stored in an enumerator, and wherein X value randomly selects in 1 to q, referred to as random back value.Every time
If it find that channel is idle, then enumerator starts to successively decrease CCA detection (each CCA detection time is identical), such as
Fruit channel is not idle, then enumerator does not successively decrease, and when enumerator is decremented to 0, then can proceed by data transfer,
Data transmission period determines according to demand, but maximum not can exceed that (13/32) × q ms.
Preferred embodiment two
This preferred embodiment executes the CCA UE that the present invention provides under by the way of FBE and executes CCA every time to UE
During frequency domain position determine and method of adjustment be described in detail.
For the mode of FBE, UE executes LBT and adopts the description to FBE in preferred embodiment one, i.e. each frame week
It is only performed once initial CCA, if the such as frame period is 1ms, UE can be able to be carried out in each subframe in phase
CCA.For the higher business of priority, such as retransmit business or the information of feedback correlation, or when base station scheduling is many
Individual UE is multiplexed in identical subframe and sends, or when UE oneself finds that the RB of scheduling is less than upstream bandwidth, it is preferred to use
This LBT mode.
Under which, the initial time-domain position that UE executes CCA is predefined value, positioned at subframe end ion frame boundaries one

Mode two：UE only carries out CCA in the resource of scheduling.
Mode three：Centered on the center of scheduling resource, the frequency domain of CCA is the frequency domain money that can include dispatching to UE
One virtual bandwidth in source, the size of virtual bandwidth is predefined value, such as 5M, 10M, 15M or 20M, or
L subband of person, or virtual bandwidth passes through for base station that signaling is semi-static or the value of dynamic instruction.
Fig. 7 is to determine schematic diagram according to the resource contention frequency domain position providing in the preferred embodiment of the present invention two, as Fig. 7 institute

Centered on center, virtual bandwidth is 5M, preferably covers system bandwidth value or the base of the minimum of the frequency domain resource of scheduling
Stand by RRC signaling or DCI signal deployment to UE value.
If UE carries out CCA success in scheduling subframe corresponding time-frequency domain position, UE is in the RB resource of scheduling
On according to base station scheduling signaling send data.
If this UE continuously dispatches multiple subframes, and the frequency domain resource position of the scheduling of next subframe is also in virtual tapes
In wide, then this UE can continuously transmit multiple subframes.
This UE is when next time is scheduled, if last time virtual bandwidth includes the resource that this UE is scheduled, should
UE first can carry out CCA detection according to virtual bandwidth before in last time corresponding frequency domain position, if the free time, permissible
Carry out data transmission.
Or, if last time CCA virtual bandwidth does not include the frequency domain resource that this UE is scheduled, this UE can be
Originally carry out a skew offset on the basis of frequency domain position, the position after skew still includes the RB, CCA of this scheduling
Frequency domain remain as predefined or signaling instruction virtual bandwidth, such as 5M.

The frequency domain of row CCA is centered on indexing the RB for 30, and the frequency domain virtual bandwidth of CCA is minimum system band
Width values 5M.If CCA success, this UE can be carried out data transfer.If it fails, data then can not be carried out
Transmission, or this UE is still to carry out data transmission less than the power predefining threshold value.
Specifically, if UE n+1 subframe scheduling frequency domain resource still in upper once CCA virtual bandwidth as Fig. 8
Shown, then this UE is that the 2nd CCA virtual bandwidth is constant in the CCA frequency domain position of n+1 subframe.
If the frequency domain resource of n+1 subframe scheduling, not in upper once CCA virtual bandwidth, has two kinds of selections：
Mode one：This UE enters line displacement offset in the CCA position of n+1 subframe on the basis of original, until comprising
The frequency domain position of scheduling, as shown in Figure 9.
Mode two, when this UE carries out CCA in n+1 subframe, centered on the center of the resource dispatched by this
Carry out the CCA detection in respective virtual bandwidth, as shown in Figure 10.
Or, when the value of the alternate position spike of the frequency domain resource dispatched twice is less than predefined thresholding, employing mode one,
When more than predefined thresholding, employing mode two.
Or, when the result of first time detection is idle, employing mode one, when first time testing result is busy
When employing mode two.
UE be can be seen that by this preferred embodiment in a virtual bandwidth, carry out CCA, and in whole system bandwidth

Resource contention frequency domain position adjustment mode schematic diagram one in bright preferred embodiment three, as shown in figure 11.
The third：The frequency domain original position of CCA or center frequency domain position and scope all change, but the frequency domain of CCA
Scope always comprises the resource dispatched.Figure 12 is according to resource contention frequency domain position adjustment side in the preferred embodiment of the present invention three
Formula schematic diagram two, as shown in figure 12.
On the contrary, when UE carries out initial CCA in full bandwidth or virtual bandwidth or extension CCA testing result meets necessarily
When condition, the frequency domain of follow-up CCA and/or position can be adjusted according to the related result of last time CCA
Or reduce.
Such as, UE can be according to the energy detecting, or CCA adds up the number of times of failure, or busy duration, or
The signaling instruction of person base station, carries out the adjustment of CCA frequency domain.
The adjustment mode that the frequency domain of CCA is reduced still can have above-mentioned three kinds：
The first：Centered on the center of the center of scheduling resource or system bandwidth, the frequency domain of CCA is reduced certain
Individual length, Figure 13 is according to resource contention frequency domain position adjustment mode schematic diagram three in the preferred embodiment of the present invention three, such as

Preferred embodiment seven
, in addition to oneself carry out CCA frequency domain position determination and adjustment according to rule, the frequency domain position of CCA is acceptable for UE
Illustrated by the method that RB that is predefined and dispatching combines determination.
Such as, predefine and system bandwidth is divided into some continuous or discontinuous overlapping virtual bandwidth set, then, UE
Carry out CCA in one or more virtual bandwidth belonging in the frequency domain resource of scheduling.
Figure 21 is to determine schematic diagram according to resource contention frequency domain position in the preferred embodiment of the present invention seven, as shown in figure 21,
Figure for the right, it is assumed that system bandwidth is 20M, if predefined virtual bandwidth is 5M, can be divided into 4.
If virtual bandwidth is 10M, 2 can be divided into.And as far as possible a UE scheduling is existed when base station scheduling
In one virtual bandwidth, it is to avoid the situation across virtual bandwidth scheduling occurs.So each scheduling of each UE has uniquely
Belonging virtual bandwidth is corresponding.
Or system bandwidth is divided into the set of several overlapping virtual system bandwidth, as shown in the left side of Figure 21, false
If the system bandwidth of 20M is divided into A, the set of the different virtual bandwidth being 5M of B, C, D, E five, two adjacent

With the offset information of MCS or RB when last scheduled, the data code modulation not be given and resource location information
Represent that the information with last time is consistent.
Or UE first sends Seize ACK message on the resource, and the resource notification of free time will be detected to base station, base station exists
Dispatch other users in this resource or this UE carries out transmitting uplink data.
Specifically, such as base station sends indication signaling to close and dispatch in this subframe with UE geographical position
UE, allows this UE send data on idling-resource.Or base station sends scheduling configured information to this UE, and UE receives
Carry out the transmission of upstream data in next subframe to after this information.

Mode one：First scheduling subframe is full bandwidth, subsequently directly continuously transmits without carrying out CCA again,
Mode two：Each scheduling subframe will carry out CCA in the frequency domain resource of scheduling.
When scheduling UE is discrete subframe, UE carries out CCA in the frequency domain resource of each subframe scheduling.
Or, UE is according to base station is semi-static or the frequency domain position of dynamic instruction carries out CCA.
Then, UE carries out LBT and data transfer according to the parameter receiving.
