In embodiment illustrated in fig. 2, there is provided a kind of ascending transmission method of user equipment side, including：
According to configuration signal, it is that the UE where the UE or described UE assembles the UGFT windows put to obtain network side by S21, UE
Configuration information.
Wherein, the configuration information includes：The cycle (being designated as ugfc-Periodicity) of the UGFT windows, and/or
Offset (be designated as ugfc-Offset) of the UGFT windows within the cycle.
Specifically, the offset and UGFT moneys of the cycle of the UGFT windows, the UGFT windows within the cycle
The specific value of the length of source unit can be weighed with absolute time, such as how many ms or with some basic time
The multiple at interval is weighed, such as multiple of subframe etc..Fig. 3 gives a kind of periodically centralized UGFT resource pools distribution
Example.
Optionally, the configuration information also includes：The number of the UGFT resource units included in the UGFT windows.
S22, the UE determine the position of the UGFT windows according to the configuration informations of the UGFT windows.
On the UGFT resource units that S23, the UE are included in the UGFT windows, uplink is carried out.
The embodiments of the invention provide a kind of centralized UGFT resource distribution modes, UE obtains network according to configuration signal
UE of the side where the UE or described UE assembles the configuration information for the UGFT windows put, and according to the configuration information, determines institute
The position of UGFT windows is stated, and on the UGFT resource units included in the UGFT windows, carries out uplink.Due to only needing
The uplink of UE or UE groups is dispatched by configuration signal, UE is realized and the UGFT windows put is assembled in the UE where the UE or the UE
Exempt from mandate uplink in mouthful, adopted because UE assembles the uplink in the UGFT windows put in the UE where the UE or the UE
Realized with authorization is exempted from, reduce signaling consumption, reduce interaction time delay, improve spectrum efficiency.
In the embodiment of the present invention, for the transmission according to system-frame-subframe for time domain timing basic structure similar to LTE
For system, network side only need by the value of two signaling elements of ugfc-Periodicity and ugfc-Offset notify to
UE, UE are the accurate original position that would know that UGFT windows.It is assumed that 5G NR continue to use similar LTE basic time domain system frame-subframe
Structure, if a system-frame system frame includes S subframe subframe and (it is assumed that NR system-frame durations are fixed, but defined
The subframe type of a variety of different lengths, then S is also corresponding a variety of values), and ugfc-Periodicity and ugfc-
Offset numerical value unit is subframe, then UE can be known corresponding to the original position of UGFT windows by following expression formula
System Frame Number (System Frame Number, abbreviation SFN) in subframe number：
SFN mod T=FLOOR (ugfc-Offset/S)；
Subframe=ugfc-Offset mod S；
With T=ugfc-Periodicity/S；
Further, UE is further according to numerical value of N, you can knows the end position of UGFT windows.ugfc-Periodicity、

Optionally, ugfc-Periodicity, ugfc-Offset and N frequency of notification or renewal frequency are not required for one
Cause, therefore, ugfc-Periodicity, ugfc-Offset and N can be sent in same signaling, can also pass through difference
Signaling is sent.
In the embodiment of the present invention, if applying UGFT on unauthorized unlicensed frequency spectrums, UE needs sending letter
Whether idle (i.e. channel idle assessment (Clear Channel Assessment, the abbreviation of unlicensed spectrum is first listened to before number
Its busy-idle condition is judged, if receiving power is less than one
Determine thresholding, then it is assumed that source is not interfered with unlicensed spectrum and is in idle condition, then sends signal in the unlicensed spectrum,
Otherwise signal is not sent.It is this in order to avoid what multi-user transmission collided/conflicted in time first monitors the machine sent afterwards
System is referred to as LBT (Listen Before Talk).
In the embodiment of the present invention, UGFT configurations (UGFT configuration, the abbreviation of different UE or different UE groups
UGFC) can be different, so as to reduce transmission collision of the multi-user on time-frequency location.
Specifically, UGFC differences include following three kinds of possible situations：
The cycle phase of the UGFT windows is same, but offset of the UGFT windows within the cycle is different；Or
Offset of the UGFT windows within the cycle is identical, but the cycle of the UGFT windows is different；Or
The offset of the cycle of the UGFT windows and the UGFT windows within the cycle is different.
When the embodiment of the present invention is applied to unlicensed spectrum, UGFT that UE described in S23 is included in the UGFT windows
On resource unit, uplink, including following two possible implementations are carried out：
Mode A, the UE setting aside some time in interval before the UGFT resource units, LBT is performed, in LBT successes
Afterwards, on the UGFT resource units, uplink is carried out.
Mode B, the UE setting aside some time in interval in the UGFT resource units, LBT is performed, after LBT successes,
On the UGFT resource units, uplink is carried out.
For mode A and mode B, wherein, described to set aside some time in interval, 1) UGFT where the UGFT resource units
Any UE corresponding to window in UE or UE groups, will not be carried out in frequency domain resource corresponding to the UGFT resource units it is up
Transmission；2) network side at least will not carry out downlink transfer corresponding to the UGFT resource units in frequency domain resource；3) network side
Uplink at least will not be carried out dispatching UE corresponding to the UGFT resource units in frequency domain resource.The interval of setting aside some time
Size depend on LBT needed for maximum time interval.
For mode A and mode B, optionally, if LBT durations are not UGFT resource units length (i.e. UGFT resource units
The duration in time domain) integral multiple, then：Network side or UE are needed in the UGFT moneys where interval initial time of setting aside some time
The transmission of part UGFT resource units is carried out on source unit.For example the length of a UGFT resource unit is 1ms (corresponding LTE
One subframe lengths), and the maximum required durations of LBT are considerably shorter than 1ms, then network side or UE can be in the 1ms subframe lengths
Carry out the transmission of part subframe.
In the embodiment of the present invention, on the UGFT resource units that UE described in S23 is included in the UGFT windows, carry out
During row transmission, including following two possible implementations：
Mode 1, the UE randomly choose K UGFT resource list from N number of UGFT resource units in the UGFT windows
Member, and on the K UGFT resource units, uplink is carried out, wherein, K ∈ [1, N '], N ' is less than or equal to N just
Integer.
Optionally, the N ' can be make an appointment or network side notified by the configuration information to institute
UE is stated, can also be that network side is signaled to the UE by other, a UE can be limited once by passing through N '
The number of transmissions in UGFT windows or the time continuously transmitted.
Optionally, network side according to UGFT transmission success situation, can adjust N ' value.
In which, the UE is after the position of UGFT windows has been known, from N number of UGFT resource units, randomly chooses K
Individual UGFT resource units carry out uplink.
Carry out uplink because different UE randomly choose different number UGFT resource units, reduce multi-user when
Transmission collision on frequency position.
When which is applied to unlicensed spectrum, after the UE randomly chooses K UGFT resource unit, at the K
LBT is carried out before UGFT resource units or in the K UGFT resource unit.If LBT successes, allow behind or where it
UGFT resource units in carry out uplink, wherein, carry out uplink particular location depend on LBT be from a UGFT
The initial time of resource unit starts or terminated in the initial time of a UGFT resource unit.If where LBT successes
One or more UGFT resource unit after UGFT resource units falls within K selected UGFT resource unit.It is optional
, UE can be continuously transmitted without carrying out LBT on adjacent UGFT resource units.
When which is applied to unlicensed spectrum, it is possible that UE is close to continuously transmitting in UGFT resource units,
Its duration is also limited to maximum channel holding time (the Maximum Channel Occupancy in unlicensed spectrum
Time, MCOT), the business of different priorities can have different MCOT.
Mode 2, the UE one random number L of selection, the L UGFT resource list in the UGFT windows from [1, N ']
In member, uplink is carried out.
Specifically, the UE randomly generates a random natural number L between [1, N '], L numerical value constrains the UE
At most allow the number of UGFT resource units taken in a UGFT window.Wherein, N ' definition is referring specifically to above-mentioned side
Associated description in formula 1.
Due to only determine the UE in the UGFT windows at most allow take UGFT resource units number, such as
What initial UGFT resource unit of selection is transmitted, including following manner：
Mode 21, in order to increase sending probability, the UE can select to begin attempt to L from first UGFT resource unit
The transmission of continuous UGFT resource units.
When which is applied to unlicensed spectrum, the UE can be attempted successively since first UGFT resource unit
LBT, if LBT successes, the UGFT resource lists that UE can in the UGFT resource units and afterwards at some UGFT resource unit
Uplink is carried out in member, but the total duration for needing to meet to transmit in a UGFT window is no more than L UGFT resource unit, and
Optionally on the UGFT resource units continuously transmitted without carrying out LBT again.Certainly, whether UE will attempt L transmission, also depend on
In the portfolio of itself.
When which is applied to unlicensed spectrum, it is possible that UE is close to continuously transmitting in UGFT resource units,
Its duration is also limited to the maximum channel holding time MCOT in unlicensed spectrum, and the business of different priorities can have not
Same MCOT.
Mode 22, in order to reduce UE transmission collision probability, the UGFT resources that the UE includes from the UGFT windows
In unit, original position of the one UGFT resource unit of random selection as uplink, uplink is carried out.
Specifically, the UE randomly chooses a UGFT resource unit as uplink in N number of UGFT resource units
Original position, UE can carry out uplink since L UGFT resource unit the UGFT resource units.
When which is applied to unlicensed spectrum, the UE can be attempted successively since in selected original position
LBT, if the LBT successes on some UGFT resource unit, the UGFT that the UE can in the UGFT resource units and afterwards are provided
Uplink is carried out in source unit, but the total duration that meet to transmit in a UGFT window is no more than L UGFT resource unit.
Optionally, without carrying out LBT again on the UGFT resource units continuously transmitted.
Obviously, in addition to MCOT limitation, the maximum duration that the UE can be transmitted additionally depends on the start bit randomly selected
Put the position in UGFT windows.Because two UGFT windows are discontinuous in time, so described in each UGFT windows
UE is required for reselecting original position.
Several M are kept out of the way in mode 23, UE random selections, the first UGFT resource unit included from the UGFT windows
Start to perform LBT, on the UGFT resource units where successfully completing LBT for the M times or UGFT resource units afterwards, carry out
Row transmission, 1≤M≤N.
Specifically, the UE, which randomly chooses one, keeps out of the way several M, then from first UGFT resource in the UGFT windows
Unit starts to attempt LBT successively, if on some UGFT resource unit LBT success, keep out of the way number retreating to M-1, only when
The UE all LBT successes on M UGFT resource unit, (it can now keep out of the way number and retreat to 0) institute in the M times success LBT
UGFT resource units or the beginning uplink of UGFT resource units afterwards.But meet what is transmitted in a UGFT window
Total duration is no more than L UGFT resource unit.For example, UGFT resource units based on random back when Fig. 4 provides M=3
Selection course.
In which, if keeping out of the way number described in current UGFT windows does not retreat to 0, the UE successfully completes LBT at the M times
On the UGFT resource units at place or UGFT resource units afterwards, uplink is carried out, including：
The UE after current UGFT windows terminate, keep out of the way by pause；And the UE next UGFT windows arrival after,
Keep out of the way number when keeping out of the way from first UGFT resource unit of next UGFT windows to suspend, start to keep out of the way.
Obviously, in addition to MCOT limitation, maximum duration that the UE can be transmitted, which additionally depends on, to be kept out of the way number and retreats to 0 when institute
UGFT resource units position.It should be noted that the UE keep out of the way number retreat to next UGFT windows after 0 when
Need to reselect and keep out of the way several M.
Based on any of the above-described embodiment, for most of types of service, UE needs to wait network upon completion of the transmission
The ACK/NACK of side confirms, just can know that whether transmission succeeds, if it fails, then needing according to hybrid autonomous retransmission
(Hybrid Automatic Repeat reQuest, abbreviation HARQ) rule retransmits the data of failure.In order to avoid UE is being transmitted
Afterwards for a long time in etc. ACK/NACK to be received state, it is necessary to be carried out about to the network side feeding back ACK/NACK specific time
Beam, if while in view of applied to unlicensed spectrum network side being also required to LBT before feeding back ACK/NACK, consolidate so can not limit
Fixed ACK/NACK delivery times, and certain offset should be reserved, that is, allow network side in the time interval of a setting
Interior transmission ACK/NACK, is referred to as ACK/NACK windows by this time interval here.Accordingly, UE described in S23 is in the UGFT
On the UGFT resource units included in window, after carrying out uplink, methods described also includes：
The UE receives the ACK/ that network side is replied in the ACK/NACK windows corresponding with the UGFT windows
NACK。
Wherein, the initial time of ACK/NACK windows can be realized using following three kinds of modes：
Initial time or finish time of the initial time of mode A, ACK/NACK window for any UGFT windows.
In which, network side can be in ACK/NACK windows for upper in the UGFT windows before the UGFT windows
The ACK/NACK feedbacks that all or part of uplink in row transmission or/and the UGLT windows is concentrated.
Initial time or finish time of the initial time of mode B, ACK/NACK window for any UGFT resource units.
For example, Fig. 5 A give initial time the showing for the initial time of any UGFT windows of ACK/NACK windows
Example, the initial time that Fig. 5 B give ACK/NACK windows are the example of the finish time of any UGFT windows.
The initial time of mode C, ACK/NACK window is spaced setting afterwards for the finish time of any UGFT resource units
At the time of duration.
For example, the initial time that Fig. 5 C give ACK/NACK windows is the finish time of any UGFT resource units
Example at the time of interval setting duration afterwards.
In which, the initial time of ACK/NACK windows corresponds to certain a period of time after UGFT resource unit finish times
Carve, the when a length of network side handle time delay reserved, to be received the decode to UE uplink.
Based on the either type in aforesaid way A~mode C, the finish time of ACK/NACK windows can pass through permission
ACK/NACK time delay values (i.e. ACK/NACK windows duration) characterize, and this time delay value can be weighed with absolute time, such as more
Few ms or weighed with the multiple at some basic time interval (such as subframe).
Obviously, two signalings are at most needed in mode A or mode B, and (this signaling can be L1 signalings (physical layer signaling), L2
Signaling (data link layer signaling), L3 signalings (high-level signaling, such as medium education (Media Access Control, abbreviation
MAC), wireless heterogeneous networks (Radio Resource Control, abbreviation RRC) etc.) or broadcast message) UE can be allowed to know
The accurate location of ACK/NACK windows, when the two signalings can be the original position and ACK/NACK windows of ACK/NACK windows
It is long, wherein, original position can use 1 bit to represent to correspond to initial time or the finish time of UGFT resource units, or UGFT
The initial time of window or finish time.If the initial time and window duration of ACK/NACK windows are system default
Value, then without any notice signaling；If the original position of ACK/NACK windows is default value, a signaling is only needed to lead to
Know ACK/NACK window durations.
At most two signalings (this signaling can be L1 signalings, L2 signalings, L3 signalings or broadcast message) are needed in mode C i.e.
UE can be allowed to know the accurate location of ACK/NACK windows, the two signalings can be network side handle time delay and ACK/NACK windows
Duration.If network side handle time delay and ACK/NACK window durations are system default value, without any notice signaling；Such as
Fruit network side handle time delay is default value, then only needs a signaling to notify ACK/NACK window durations.
Further, the UE receives the ACK/NACK packets that the network side is replied in the ACK/NACK windows
Include following four situation：
If the 1, receiving the ACK that the network side is replied, the UE need not be retransmitted；
If the 2, the UE receives the NACK that the network side is replied in the ACK/NACK windows,：The UE exists
On UGFT resource units after the ACK/NACK windows, retransmitted；Or the UE the ACK/NACK windows it
On the UGFT resource units included in next UGFT windows afterwards, retransmitted.
Optionally, the difference that the HARQ data version of re-transmission can retransmit with initial transmission or last time.
If the 3, the UE receives the dispatch for re-transmission of network side transmission in the ACK/NACK windows,
The UE is retransmitted on the resource unit scheduled in the dispatch.
Optionally, if the scheduling for re-transmission that the UE receives network side transmission in the ACK/NACK windows is believed
ACK/NACK information is also have received when making, then ignores the ACK/NACK information.
Optionally, the resource unit indicated by the dispatch is non-UGFT resource units.
If the 4, the UE does not receive any reply of network side in the ACK/NACK windows,：
The UE is retransmitted on the UGFT resource units after the ACK/NACK windows；
Or the UGFT resource units that the UE is included in next UGFT windows after the ACK/NACK windows
On, retransmitted.
Optionally, the HARQ data version of re-transmission can retransmit identical with initial transmission or last time.
