Such as, first time window 305 or 40 can include arbitrary an appropriate number of sub-frame set, and can include appointing in each sub-frame set
It anticipates an appropriate number of DL subframe and UL subframe.
In accordance with an embodiment of the present disclosure, the first communication equipment 110 can determine rising for first time window in any suitable manner
Begin the time.In certain embodiments, the first communication equipment 110 can be directed to unauthorized frequency in response to the duplication of signal to be sent
Spectrum performs LBT processes.After idle channel is detected, the first communication equipment 110 can make the initial time for accessing channel
Initial time for first time window.It should be understood that the first communication equipment 110 can be fitted with that will initiate the arbitrary of signal transmission
When initial time of the other times as first time window.
In accordance with an embodiment of the present disclosure, the first communication equipment 110 can determine first time window in arbitrary opportune moment
Window length (is known as " the first window is long ").For example, the first communication equipment 110 can determine at the first time before the duplication for sending signal
First window of window is long.Alternatively, the first communication equipment 110 can determine that the first window is long during signal is sent.It is specific real
Applying example will be described in detail later.
First communication equipment 110 can be long based on arbitrary appropriate the first window because usually determining first time window.It is sending
In the embodiment that the first window length is determined before the duplication of signal, the first communication equipment 110 can determine the based on historical experience
One window is long.For example, signal will be previously sent duplication when used window length it is long as the first window.Alternatively, the first communication is set
Standby 110 can determine that the first window is long according to channel fading profiles.For example, the first communication equipment 110 can send signal
Channel fading or congestion situation are determined before replicating.If channel fading or congestion are more serious, the first communication equipment 110 can be with
Determine that the first longer window is long.In addition, the first communication equipment 110 is also based on the feature of signal to be sent to determine reference
Time window.For example, if signal to be sent is the control signal for including less information bit, the first communication equipment 110 can
To determine that first time window is long with the first shorter window.And for the data-signal for including more information bit, the first communication
Equipment 110 can determine that first time window is long with the first longer window.
In certain embodiments, the first communication equipment 110 can be grown to determine first based on the reference window of reference time window
First window of time window is long.First communication equipment 110 can determine that the first window is long to be grown based on reference window in any suitable manner.Make
For example, the first window of first time window can be grown reference window of the fixed setting for reference time window by the first communication equipment 110
It is long.
Additionally or alternatively, in order to further enhance covering, what the first communication equipment 110 can also be grown in reference window
On the basis of, the number of the duplication based on the signal to be sent is long dynamically to adjust the first window of first time window.With reference to Fig. 5
One specific example of the first window length that first time window is dynamically adjusted on the basis of reference window length is discussed.
Fig. 5 shows the dynamic adjustment first time at the first communication equipment 110 of some embodiments according to the disclosure
The exemplary method 500 of the first window length of window.As shown in the figure, in frame 505, the first communication equipment 110 determines and reference time window phase
The reference number of associated signal replication.This can arbitrarily appropriate ways be determined with reference to number.For example, sending answering for signal
In the embodiment of the first window length that first time window is determined before system, the first communication equipment 110 can pre-estimate the reference time
The number of the duplication for the signal that can be sent in window, and using estimated number as with reference to number.Sending signal replication
During determine the first window length embodiment in, the first communication equipment 110 can first with the reference time window send believe
Number some duplication.After reference time window, the first communication equipment 110 determines to have had sent in reference time window more
It is few to replicate, then it can refer to number using the number of the duplication sent as this.
After determining with reference to number, in frame 510, the first communication equipment 110 to that will send in the first time window
The number of duplication be compared with identified with reference to number.In frame 515, if the number for the duplication that will be sent is more than ginseng
Number is examined, that is, reference time window cannot accommodate enough duplications, then the first communication equipment 110 determines first time window
The reference window that first window length should be more than reference time window is long.
By this method, the first communication equipment 110 can dynamically adjust first according to the practical transmission demand of signal replication
First window of time window is long.For example, it is more serious in channel fading and when needing to send more signal replication, the first communication equipment
110 can send signal using longer first time window.In addition, based on reference time window dynamic in signal transmission process
The mode of the first window length of first time window is adjusted, can channel for example can not be successfully accessed so as to lead due to LBT failures
In the case that cause reference time window cannot accommodate enough duplications, signal is sent using longer first time window, so as to true
Covering performance needed for protecting.
It describes to determine first time window based on the reference window length of reference time window below with reference to Fig. 6, Fig. 7 (a) and Fig. 7 (b)
The first window length specific example.Referring initially to Fig. 6, it illustrates grow to determine based on reference window before the duplication for sending signal
The example timing of first window length.In this example, reference time window 605 includes three continuous frames 610 (being labeled as " F ").The
One communication equipment 110 determines that in reference time window 605 enough letters can not be sent by estimation before signal replication is sent
Number replicate, then first time window 610 is determined as to include three reference time windows 605.
It should be understood that the reference window length of reference time window shown in fig. 6 is only exemplary rather than limiting.According to the reality of the disclosure
Example is applied, reference time window can be long with arbitrary appropriate reference window.For example, reference time window can be including arbitrary an appropriate number of
Frame or subframe.
It should also be understood that the first window length of identified first time window is also only exemplary rather than limiting.First time window
It can include the reference time window of arbitrary suitable multiple.As an example, first time window can include the reference time of integral multiple
Window, for example, M=2N, 3N ..., wherein M be first time window the first window it is long, N is that the reference window of reference time window is long.As
Alternative example, first time window can include non-integral multiple reference time window, for example, M=(1+1/2) N, (1+1/4) N ....
Fig. 7 (a) and Fig. 7 (b), which shows to grow based on reference window during signal replication is sent, determines the first window length
Example timing, wherein Fig. 7 (a) shows repeatedly determining example timing, and Fig. 7 (b) shows the example timing that single determines.
In the example shown in Fig. 7 (a), three reference times window 705-1,705-2 and 705-3 (are referred to as " the first reference time window
705-1 ", " the second reference time window 705-2 " and " third reference time window 705-3 ", are referred to as " reference time window 705 ") it is every
It is a all to include three continuous frames 610.First communication equipment 110 sends signal first in the first reference time window 705-1
Multiple duplications.At the end of the first reference time window 705-1, because there is no whole signal replications is sent, first is logical
Believe that equipment 110 determines that (715) first time window 710 should also include the second reference time window 705-2, that is, including two references
Time window 705.
Equally, at the end of the second reference time window 705-2, still without sending whole signal replications, so first
Communication equipment 110 determines that (720) first time window 710 should also include third reference time window 705-3 again, that is, including three
Reference time window 705.At the end of third reference time window 705-3, the first communication equipment 110 has had sent all duplications,
Thus finally determining (725) first time window 705 includes three reference time windows 705 to the first communication equipment 110.
Shown in Fig. 7 (b) two reference time windows 730 and 735 (be referred to as " the 4th reference time window 730 " and
" the 5th reference time window 735 ").First communication equipment 110 sends the multiple multiple of signal in the 4th reference time window 730 first
System.At the end of the 4th reference time window 730, the first communication equipment 110 determines also have some signal replications not yet to send, and then
Determine that (740) first time window 745 should also include the 5th reference time window 735.
Although should be understood that in Fig. 7 (b), the 4th reference time window 730 and the 5th reference time window 735 are each shown as wrapping
Three continuous frames 610 are included, but this is only exemplary rather than limiting.In certain embodiments, the first communication equipment 110 can be with
At the end of the 4th reference time window 730, determine to also need to time window how long based on the number of signal replication to be sent
To send remaining duplication.That is, the first communication equipment 110 can determine the 5th reference based on the number of duplication to be sent
The reference window of time window 735 is long.
It next proceeds to reference to figure 2, in frame 215, the first communication equipment 110 sends finger associated with first time window
Show.As described above, although the duplication for sending signal instruction associated with sending first time window is illustrated as detaching at two
Frame in independently execute two actions, but this is not offered as that the two actions are inevitable independently to be performed.In some embodiments
In, the duplication of signal can be sent together with associated instruction in the first time window, specific example carries out later
It is described in detail.
Above-mentioned instruction can indicate arbitrary adequate information associated with first time window.In some embodiments, the instruction
It can indicate that the first window of first time window is long.Correspondingly, recipient's (such as second communication equipment 120) can be according to the instruction
To detect the duplication of the signal transmitted by sender, and the signal is detected according to these duplications.The specific implementation of recipient
Example will be described in detail with reference to figure 10 later.
Additionally or alternatively, which also can indicate that the signal sent in the first time window, so as to recipient
Indicate which signal transmitted duplication belongs to.Such instruction for signal can also indicate transmitted duplication to recipient
Which time window belonged to, because all duplications sent in a time window can belong to same signal.By simultaneously
The instruction of the first window length of first time window and the instruction of signal transmitted in the first time window are sent, recipient can be with
Double check is carried out to instruction, so as to find the flase drop of instruction or missing inspection in time, and the corresponding detection of corrigendum in time is wrong
Accidentally.
In some other embodiments, it is after instruction associated with first time window also can indicate that first time window
It is no to also have another time window (being known as " the second time window ").For example, the first communication equipment 110 can determine first time window it
Whether there is another part to replicate afterwards to be sent.If the first communication equipment 110 only has sent to be sent in the first time window
A part for signal replicates, then the first communication equipment 110 can determine also to need to send another portion after first time window terminates
Divide and replicate.Then, the first communication equipment 110 can determine the second time window for sending another part duplication.Second time
The determination process of window is similar with the determination process of above-described first time window, therefore details are not described herein.
After the second time window is determined, the first communication equipment 110 can be sent after first time window when also having second
Between window instruction as instruction associated with first time window, so as to recipient's instruction still need to after the first timing window after
It is continuous that the duplication of signal is detected.Additionally or alternatively, the first communication equipment 110 can send the second time window window it is long
The instruction of (being known as " the second window is long ") is as instruction associated with first time window.Second window length instruction can be also used for
Recipient implicitly indicates there be the second time window after the first timing window.If the first communication equipment 110 is determined first
All duplications of signal are had sent in time window, then the first communication equipment 110 does not have after can sending first time window
