This part, mainly provides a kind of method for improving SRS transmission chance, i.e. UE has at least one Individual character position can be used for carrying out SRS transmission.

Wherein, there are two kinds of situations in the SRS character positions of candidate, transmission SRS：

One kind is：User equipment (UE) has carried out SRS on one of SRS time-domain symbols position of candidate Transmission, SRS transmission is no longer carried out on remaining candidate's time-domain symbol position.

I.e. if user equipment (UE) is competed before the SRS character positions of candidate to unauthorized carrier wave The right to use (successfully completes LBT processes according to specific LBT mechanism, that is, thinks that user's competition is arrived The right to use of unauthorized carrier wave), then UE transmits SRS on current SRS character positions.For The UE, abandon transmitting in other SRS character positions of candidate, or, other SRS symbols of candidate Number position failed for the UE.

Another kind is：User equipment (UE) have sent on one of SRS time-domain symbols position of candidate SRS, remaining candidate's time-domain symbol position still can use for the UE.

I.e. if user equipment (UE) is competed before the SRS character positions of candidate to unauthorized carrier wave The right to use (successfully completes LBT processes according to specific LBT mechanism, that is, thinks that user's competition is arrived The right to use of unauthorized carrier wave), then UE transmits SRS on current SRS character positions.Waiting Other SRS character positions of choosing are also transmitted, alternatively, if the SRS character positions of candidate It is continuous in time domain, then UE can be transmitted directly in the SRS time-domain symbols position of candidate, not had to Perform LBT.Conversely, if the SRS character positions of candidate are discrete in time domain, UE is in candidate SRS time-domain symbol position on be transmitted before, it is still desirable to perform LBT mechanism (LBT Mechanism LBT mechanism performed when can be than being successfully transmitted SRS more simplifies (for example, 25us LBT Cat2), or, using the n values in smaller contention window and defer period), obtaining To unauthorized carrier wave the right to use on the premise of, can just be passed on the time-domain symbol position of candidate It is defeated.Or if the SRS character positions of candidate are discrete in time domain, UE is being successfully transmitted Sent on SRS time-domain symbol position to the blank character between next SRS time-domain symbols position dilute Thin Seize ACK message.

It is presented below the different OFDM symbol numbers of definition and SRS that UE candidates can transmit is accorded with The corresponding relation of number position.A total form can be equally formulated, i.e., can be inquired about in this form The SRS transmission character position corresponding to distinct symbols into a subframe.Such as table 10.

When being for different OFDM symbol numbers below, the SRS transmission character position of UE candidates.

During 9 OFDM symbols, the SRS of corresponding UE candidate transmission character position.

Table 12 according to remaining symbolic number in descending tail portion subframe be 9 when, corresponding UE candidate SRS transmission character position

Because remaining symbolic number is 9, or, 10, or, 11, or, 12 in subframe, or, 14 During OFDM symbol, the SRS of corresponding UE candidate transmission character position number of combinations is too many, here Just do not enumerate one by one.The residue 9 in for a subframe, or, 10, or, 11, or, 12, or, During 14 OFDM symbols, the method for corresponding candidate's SRS transmission character position is same as above, Ye Shiben Within the scope of invention protection.

If triggering the physical layer DCI signalings of SRS transmission, e.g., the proprietary DCI signalings of UE (for example, The signalings of format 0/4), or, group DCI signalings (for example, format 3/3A), or, DL Grant (for example, format 1A/2B/2C) signalings are sent in subframe n, according to existing LTE protocol In n+k1 (wherein, k1 4) timing relationship, determine the time-domain position of SRS transmission.Enter one Step, the SRS transmission subframe determined according to n+k1 timing relationships terminate for downlink transfer burst Tail portion subframe, the physical layer DCI signalings for triggering SRS transmission should be in downlink transfer burst The tail portion subframe of end starts, and is sent in k1 subframe forward.Fig. 3 is according to the present invention A kind of signal that SRS transmission subframe position is determined according to timing relationship n+k of preferred embodiment Figure, as shown in figure 3, in order to ensure SRS is in the tail portion subframe that downlink transfer burst terminates Transmission, trigger the schematic diagram of the subframe of the DCI signalings transmission of SRS transmission.

By Fig. 3, subframe n is sent according to the DCI signalings that SRS transmission is triggered in existing LTE protocol, The subframe position of SRS transmission is determined according to n+4 timing relationships, alternatively, according to high-rise RRC The SRS transmission character position of signal deployment, character positions of the UE in the subframe of SRS transmission Upper transmission SRS premise is：LBT mechanism is performed before SRS character positions, if UE is in SRS LBT successes are performed before character position, then UE SRS symbols on transmit SRS.Conversely, If UE performed before SRS character positions LBT failure, UE SRS symbols on do not pass Defeated SRS.Or UE does not perform LBT before SRS character positions, as long as downlink transfer burst End position is not more than 16us to the gap between SRS character positions, or, 25us.If SRS Subframe where the character position of transmission is located at MCOT, and (MCOT may be considered downlink transfer Burst+ uplink burst, or, MCOT is considered independent downlink transfer burst, or, MCOT is considered independent uplink burst) in, then before the time-domain symbol of SRS transmission Perform 25us Cat2LBT.If the subframe where the character position of SRS transmission is located at MCOT (MCOT may be considered downlink transfer burst+ uplink burst, or, MCOT thinks It is independent downlink transfer burst, or, MCOT is considered independent uplink burst) outside, Or first subframe in MCOT, then SRS transmission time-domain symbol or subframe Cat4LBT is performed before.Preferably, can with the high LBT priority of configuration preference level, such as, Priority level 1 (e.g., maximum contention window 5, minimum competition window 0, the n in defer period For 0, or, 1, or, 2), or, priority level 2 (e.g., maximum contention window 7, it is minimum competing Striving window 3, the n in defer period is 0, or, 1, or, 2).Alternatively, upward signal or letter The priority in road is：SRS>PUSCH+SRS>PUSCH.Or the parameter n in LBT mechanism, And/or random back value N is configured by physical layer DCI signalings, or, high-rise RRC signaling.

Another situation：If trigger the physical layer DCI signalings of SRS transmission, e.g., the proprietary DCI of UE Signaling (for example, the signalings of format 0/4), or, group DCI signalings (for example, format 3/3A), Or DL grant (for example, format 1A/2B/2C) signaling, or, public DCI signalings (example Such as, format 1C) sent in subframe n, according to new n+k (wherein, k be more than or equal to 0, Or k is positive integer more than or equal to 4) timing relationship, determine the time-domain position of SRS transmission. Wherein it is preferred to k 0,1,2,3,4,5,6 etc..K is the 0 DCI letters for representing triggering SRS transmission Order is sent on subframe n, and the subframe of determination SRS transmission is also subframe n.And if k is 1, Represent that the DCI signalings of triggering SRS transmission are sent on subframe n, SRS is determined according to n+1 relations Transmission is on subframe n+1.Now, UE it is determined that SRS transmission subframe in it is specific which Transmission is determined by high-rise RRC signaling on symbol.Fig. 4 is one kind according to the preferred embodiment of the invention The first schematic diagram of the subframe position of SRS transmission is determined according to timing relationship n+k1；Fig. 5 is A kind of time domain that SRS transmission is determined according to timing relationship n+k1 according to the preferred embodiment of the invention Second schematic diagram of frame position；As shown in figure 4, or, shown in Fig. 5.

Citing 2：Citing 2 is that UE has the SRS transmission of multiple candidates with 1 difference of citing Time-domain symbol position.It is assumed that (the i.e. high-rise RRC of sequence number 174 in high-rise RRC signaling allocation list 12 The position that OFDM symbol call number is 13,10,6,5 in configuration subframe is the SRS transmission time domain of candidate Character position).Specific SRS is transmitted on which subframe passes through physical layer DCI signalings, or Person, the time-domain position of SRS transmission is configured by continuing to use high-rise RRC signaling.Wherein, SRS is triggered The physical layer DCI signalings of transmission, e.g., the proprietary DCI signalings of UE (for example, the signalings of format 0/4), Or group DCI signalings (for example, format 3/3A), or, DL grant are (for example, format 1A/2B/2C) signaling, or, public DCI signalings (for example, format 1C) are sent out in subframe n Send, the timing relationship of the time-domain position of its determination SRS transmission, can according to existing n+4, or, According to new n+k (wherein, k be more than or equal to 0, or, k is the positive integer more than or equal to 4) Timing relationship, specific method is the same as citing 1.

Alternatively, in the SRS transmission time-domain symbol position of candidate, if UE is in the symbol of first candidate LBT successes are performed before number position, then UE transmits SRS on first character position.Conversely, If UE performed before the character position of first candidate LBT failure (LBT mechanism LBT Cat4, And maximum contention window is 5, minimum competition window is that n is 1 in 1, defer period.Or LBT Mechanism is 25us Cat2), then UE abandons transmitting SRS on first character position.Continue to taste Examination performs LBT (now in the SRS of next candidate before the SRS character positions of next candidate LBT mechanism is performed before character position can be with the LBT of execution before previous SRS character positions Mechanism is identical, or, the LBT mechanism than being performed before previous SRS character positions more simplifies, Or, faster access the LBT mechanism or parameter (LBT mechanism LBT Cat4, and maximum contention of channel Window is 3, and minimum competition window is that n is 0, or, 1 in 0, defer period, or, LBT mechanism For 25us Cat2)), if performing LBT successes, UE is transmitted on current SRS symbols. Conversely, LBT fails, UE continues to attempt to perform LBT before next SRS character positions.Weight The multiple above method.Wherein, institute UE is successfully transmitted SRS on one of SRS symbols of candidate, its The transmission SRS of his candidate character position fails for the UE, or, the UE continues in candidate SRS character positions before perform LBT, under the premise of LBT is successful, send SRS.

Further, since the character position of SRS transmission, or, the sign bit of the SRS transmission of candidate It is that high-rise RRC is configured to put, and at least one of SRS transmission character position can determined by the configuration Can be the symbol in descender subframe, or, UE sides LBT unsuccessfully causes the SRS symbols of configuration Position may not transmit.This to a certain degree on limit the chance that SRS is transmitted in the subframe of part.

Mode two：Physical layer DCI signalings trigger SRS transmission, and notify the symbol of SRS transmission Position, or, the SRS transmission character position of candidate.

Wherein, SRS transmission subframe, or, SRS transmission time domain are determined by DCI signalings Frame collection location is by specific timing relationship.Specific timing relationship includes one of the following：It is existing N+4 timing relationships in LTE protocol；Or according to new definition relation n+k.Wherein, k is More than or equal to 0, or, k is the positive integer more than or equal to 4, it is preferable that k 0,1,2,3,4,5,6 Deng.The subframe position of SRS transmission is determined by timing relationship, or, the SRS of candidate is passed The method of defeated character position is the same as in method one.Parameter k can be by physical layer in specific timing relationship DCI signalings, or, high-rise RRC signaling determines.

It is with the difference of method one, UE is signaled specifically in SRS by DCI by base station Which of subframe of transmission, or, transmit SRS on which symbol.Wherein, base station only needs Notify the sequence index number in form in embodiment, you can know the time-domain symbol position of SRS transmission, Or the SRS transmission time-domain symbol position of candidate.

For mode two, base station is known that remaining symbol in downlink transfer burst tail portion subframes Number, so as to be corresponding to the corresponding remaining number of symbols of UE notices in the form from embodiment 1 SRS transmission character position, or, the SRS transmission character position of candidate.

Mode three：Physical layer DCI signalings trigger SRS transmission, and UE can pass through the public of inspection The implicit time-domain symbol position for determining SRS transmission of remaining symbolic number that DCI is obtained, or, candidate's The time-domain symbol position of SRS transmission.

For mode three, SRS transmission can be triggered by a physical layer DCI signaling, and SRS The subframe position of transmission, or, the SRS transmission subframe position of candidate can still pass through spy Fixed timing relationship determines.Wherein, specific timing relationship is one of the following：

N+4 timing relationships in existing LTE protocol；Or

According to new definition relation n+k.

Wherein, k be more than or equal to 0, or, k is positive integer more than or equal to 4, it is preferable that k For 0,1,2,3,4,5,6 etc..The subframe position of SRS transmission is determined by timing relationship, or, The method of the SRS transmission character position of candidate is the same as in method one.Parameter k in specific timing relationship Can by physical layer DCI signalings, or, high-rise RRC signaling determines.

Further, UE SRS specific character position is transmitted in descending tail portion subframe can be with Determination is implied according to the remaining symbolic number known to the public DCI signalings that UE is checked, or, in advance The mode of definition determines, or, the mode that base station and UE arrange in advance determines.

The implicit character position for determining transmission SRS, including one below：Downlink transfer burst end Last symbol in portion subframe, or, in downlink transfer burst tail portion subframe Penultimate symbol, or, first in downlink transfer burst tail portion subframe symbol Number, or, second symbol in downlink transfer burst tail portion subframe, or, it is descending The 3rd symbol in burst tail portion subframe is transmitted, or, specific one symbol, or Person, the notation index in downlink transfer burst tail portion subframe are the symbol of even number, or, Notation index in downlink transfer burst tail portion subframe is the symbol of odd number, or, it is specific Assemble of symbol.

Specific one symbol, or, specific assemble of symbol can be prior by base station and UE Agreement, or, mode is predefined, or, high-rise RRC configurations, or, physical layer DCI leads to Know.

For example, when remaining symbol is 3 in downlink transfer burst tail portion subframe, UE can be with According to last symbol in implicit remaining 3 symbols of determination of remaining 3 symbols, or, the One symbol, or, second symbol, or, first symbol and the 3rd symbol, or, Second symbol and the time-domain symbol position that the 3rd symbol is SRS transmission.

Mode four：First physical layer DCI signalings trigger SRS transmission, the second physical layer DCI instructions The sequence index of SRS transmission.

Wherein, first physical layer DCI signaling only triggers SRS transmission, and passes through the second physical layer DCI determines the subframe of SRS transmission or the subframe position of candidate, and, the symbol of SRS transmission Number position, or, the SRS transmission character position of candidate.Fig. 6 is according to the preferred embodiment of the present invention The first DCI signalings triggering SRS transmission, the 2nd DCI signalings are according to n+k or n+k1 timed-shutoffs The subframe position for the SRS transmission that system determines and/or the signal of the time-domain symbol position of SRS transmission Figure, as shown in Figure 6.

The subframe that first physical layer DCI signalings are sent is located at the transmission of the second physical layer DCI signalings Before subframe position.Alternatively, the subframe that the first physical layer DCI signalings are sent can also After the second physical layer DCI signalings send subframe position.That is, the former is first tactile Hair SRS transmission, and the subframe position of specific SRS transmission, or, the SRS of candidate is passed Defeated subframe position, and, the sequence index number of SRS transmission is notified by secondary physical floor DCI To UE.The sequence index of SRS transmission is the sequence index number in form in embodiment 1.Then Person is to first pass through a physical layer DCI and signal UE to determine SRS according to specific timing relationship The subframe position of transmission, or, the subframe position of the SRS transmission of candidate, and, SRS The sequence index number of transmission, and first physical layer DCI is triggered by second physical layer DCI signaling The subframe position of the SRS transmission of signal deployment, or, time domain of the SRS transmission of candidate Frame position, and, the sequence index number of SRS transmission is enabled.

In addition, another situation, the first physical layer DCI signalings, and/or, the second physical layer DCI The subframe of SRS transmission or the time domain of candidate can be determined in signaling by specific timing relationship Subframe position.Wherein, specific timing relationship is one of the following：N+4 in existing LTE protocol Timing relationship；Or according to new definition relation n+k.K be more than or equal to 0, or, k is big In the positive integer equal to 4, it is preferable that k 0,1,2,3,4,5,6 etc..SRS is determined by timing relationship The subframe position of transmission, or, the method for the SRS transmission character position of candidate is the same as in method one. In specific timing relationship parameter k can by physical layer DCI signalings, or, high-rise RRC signaling It is determined that.

Fig. 7 be first DCI signalings triggering SRS transmission according to the preferred embodiment of the invention and by According to the subframe position of n+k timing relationships instruction SRS transmission, the 2nd DCI signalings are according to n+k1 Timing relationship determines the schematic diagram of the time-domain symbol position of SRS transmission, as shown in fig. 7, the first physics Layer DCI signalings determine the subframe of SRS transmission or the subframe position of candidate, and second Physical layer DCI indicates the character position of SRS transmission, or, the SRS transmission character position of candidate.

Mode five：First physical layer DCI signalings trigger SRS transmission, the second physical layer DCI instructions UE determines the subframe of SRS transmission or the subframe position of candidate according to specific timing relationship, The character position for the SRS that specific UE is transmitted in descending burst tail portions, or, candidate's Transmit the remaining symbol that SRS character position can be known by the UE public DCI signalings detected Number is implicit to be determined.

SRS transmission is triggered according to first physical layer DCI signaling and refers to that UE can receive triggering SRS is transmitted in SRS transmission subframe after SRS transmission signaling.And the time domain of SRS transmission The subframe position of subframe or candidate are according to specific timed-shutoff by the second physical layer DCI signalings System determines.

Specific timing relationship, and, according to remaining symbol in downlink transfer burst tail portion subframes The implicit time-domain symbol position for determining SRS transmission of number, or, the side of the time-domain symbol position of candidate Method is the same as the method in other method in the present embodiment.

Mode six：Triggered by physical layer DCI signalings and clearly notify the subframe of SRS transmission Or the subframe position of candidate, and/or, SRS character position is transmitted, or, the biography of candidate Defeated SRS character position.

Wherein, two kinds of situations are included for mode six：

Preferred embodiment 3

In the preferred embodiment, there is provided a kind of different UE in different SRS character positions, or, Identical SRS character positions, or, transmission SRS side on identical candidate's SRS character positions Method.

Situation 1：One SRS character position situation of identical is configured for different UE, UE is passed Defeated SRS method.

For situation 1, it is assumed that when remaining symbol is 6 in downlink transfer burst tail portion subframes, SRS transmission symbol is last symbol (e.g., notation index #13) in remaining 6 symbols, SRS The mode of transmission includes one below：

Mode one：Different UE perform LBT before SRS character positions, and introduce self-dalay mechanism. Wherein, self-dalay can in LBT mechanism, or, LBT mechanism end.Fig. 8 is according to this During the time-domain symbol position of the different UE configuration identical SRS transmissions of invention preferred embodiment, The schematic diagram of self-dalay operation is introduced in LBT mechanism, as shown in figure 8, different UE can be configured Identical LBT mechanism, and/or, LBT parameter sets.For example, UE1 and UE2 configuration identicals LBT Cat4 mechanism, and the n in random back value N, defer period.Wherein, self-dalay mechanism It can be detected with UE when N values are decremented to 1 and start self-dalay before SRS symbols, accorded with SRS As long as the 9us UE before number detect that channel idle can send SRS in SRS symbols.Or Self-dalay UE after N values are decremented to 0 starts to perform self-dalay.Wherein, minimum particle size in self-dalay For 9us, i.e. self-dalay time domain length is 9us integral multiple, or, it is the whole of specific CCA durations Several times.Specific CCA durations can be 16us, or, 25us.

In addition, different UE can use Cat2LBT, in downlink transfer burst terminating symbols position To performing multiple CCA durations between SRS character positions.Wherein, the number of CCA durations is performed Equal to downlink transfer burst terminating symbols position to SRS character positions duration divided by CCA durations institute It must be worth and round.Institute's downlink transfer burst terminating symbols position to SRS character positions duration is not CCA The integral multiple of duration, then UE performs the CCA detections of a residual time length in remaining duration, A length of remaining duration during its CCA.CCA durations can be 16us, or, 25us, or, 34us, or, 43us.

Alternatively, when downlink transfer burst finish times to the gap between the character position of SRS transmission No more than 16us, or, during 25us, UE can not perform LBT mechanism and directly transmit SRS.

Mode two：Remaining symbolic construction in descending tail portion subframe：CCA gap1+ Seize ACK messages+ CCA gap2+SRS.Wherein it is preferred to Seize ACK message can be format4 PRACH (or cut Short PRACH) or short structure PUCCH.Alternatively, in remaining symbolic construction extremely At least one of few CCA gap1 and CCA gap2.Fig. 9 is according to the preferred embodiment of the invention Spatial structure schematic diagram in downlink transfer burst tail portion subframes, as shown in figure 9, working as descending biography The gap that defeated burst finish times start to Seize ACK message between sending is not more than 16us, or, 25us When, UE can not perform LBT mechanism and directly transmit Seize ACK message.Alternatively, different UE hairs The Seize ACK message sent can be multiplexed by frequency division manner, or, passed through using different cyclic shift modes Code division mode is multiplexed.I.e. CCA gap1 can be omitted.Further, different UE are in CCA gap2 In can use identical LBT mechanism, and/or, LBT parameter sets carry out channel access.

In addition, different UE configurations identical SRS character positions, wherein, different UE are same Transmission can use different cyclic shifts in SRS symbols, and/or, different transmission broach.No The cyclic shift used with UE, and/or, transmission broach can be configured by high-rise RRC signaling, and/ Or, physical layer DCI signal deployments.Wherein, cyclic shift span [0~7], or, [0, s1], It is [0,1] to transmit broach span, or, [0,3], or, [0, s2].Wherein, s1 be more than etc. In 7 positive integer.S2 is the positive integer more than or equal to 3.

Situation 2：A different SRS character position situations is configured for different UE, UE is passed Defeated SRS method.

Illustrate herein below in row transmission burst exemplified by remaining symbol in downlink transfer burst tail portions In molecule frame in remaining symbol, different UE configure different SRS character positions.Figure 10 is root According to the preferred embodiment of the present invention, different UE are configured not in downlink transfer burst tail portion subframes The schematic diagram of same SRS transmission time-domain symbol, as shown in Figure 10, different UE configurations are different SRS character positions, and different UE perform CCA position be preferably SRS character positions before A symbol, or, preceding P symbol.P is the symbol more than or equal to 1, and is less than descending biography Defeated burst tail portions subframe residue symbolic number subtracts particular value.Wherein, top grade value can be 1,2,3,4,5 Or in descending burst tail portions subframe SRS number of symbols.

Wherein, different UE configure different SRS character positions, alternatively, different SRS symbols The different UE of position can configure different transmission broach, and/or, cyclic shift, or, configuration Identical transmits broach, and/or, cyclic shift.Different UE in same SRS character positions can To configure different transmission broach, or, cyclic shift.Cyclic shift, and/or, transmission broach can be with Configured by high-rise RRC signaling, and/or, physical layer DCI signal deployments.Wherein, cyclic shift takes It is worth scope [0~7], or, [0, s1], transmission broach span is [0,1], or, [0,3], or Person, [0, s2].Wherein, s1 is the positive integer more than or equal to 7.S2 is the positive integer more than or equal to 3. The different SRS character positions of different UE configurations can be by the configuration in embodiment 1 and embodiment 2 The method of SRS character positions.

Situation 3：Identical candidate's SRS character position situations are configured for different UE, UE is passed Defeated SRS method.

For situation 3, different UE configuration identical candidate's SRS character positions, wherein, candidate SRS character positions can be continuous in time domain, multiple symbols composition that can also be discrete in time domain.

The identical SRS character positions of different UE configurations and the configuration in embodiment 1 and embodiment 2 The method of SRS character positions is identical.

Wherein, in the SRS character positions of candidate, it is preferable that in same SRS character positions Different UE configures different transmission broach, and/or, cyclic shift.Since so, when multiple When at least one of UE performs CCA failures before the SRS character positions of candidate, next Success before SRS character positions, and transmitted on current SRS symbols, will not also it cause resource to touch Hit.Alternatively, SRS is successfully transmitted in one of the SRS character positions of candidate UE, other times The SRS symbols of choosing, the UE can continue executing with LBT and send SRS, or, do not send SRS. Or do not perform LBT and directly transmit SRS.

Preferably, the SRS character positions of candidate can be discrete in time domain.For example, UE is configured Candidate SRS transmission character position be 13,11,9.Before CCA position is symbol 9, symbol 10, symbol 12.If UE1 performs LBT successes before symbol 9, UE uploads in symbol 9 Defeated SRS.If UE1 is when that will continue to transmit SRS on symbol 11, behaviour of the UE1 in symbol 10 Work has two kinds：One kind, UE sends to send preserved signal in specific resources or take in symbol 10 to be believed Number.Another kind, UE perform LBT in symbol 10.LBT can be LBT CaT4, minimum competing Strive window 0 or, 1, maximum contention window 5, n is 0, or, 1 in defer period.Or LBT Can be Cat2 LBT.Specific resources are specific RE or RB or RBG or subband.That is UE1 Send Seize ACK message or preserved signal in specific resource, the resource on frequency domain in addition to specific resources On blank in advance.Preferably, the LBT that UE1 is performed in the symbol 10 can with before symbol 9 The LBT mechanism of execution is identical, or, the LBT that can more simplify, or, shorter competition Window.Or Cat2 LBT, and a length of 25us during CCA.If on symbol 11 transmit SRS into Work(, the SRS character position transmission methods of its candidate are same as above.Another kind is, if UE1 is in symbol 9 LBT successes are performed before, then UE transmits SRS on symbol 9.On the symbol 11,13 of candidate UE1 can not send SRS.

If UE1 performs LBT failures before symbol 9, continuing in symbol 10, or, symbol LBT is continued executing with before 11, wherein, in symbol 10, or, the LBT performed before symbol 11 Mechanism can be identical with the LBT mechanism performed before symbol 9, or, than being performed before symbol 9 LBT mechanism more simplify, or, shorter contention window, or, Cat2 LBT, and CCA Shi Changwei 25us.That is, LBT failures are performed before current SRS character positions in UE, The LBT mechanism that next SRS character positions perform can be with previous SRS semiology analysis LBT Mechanism is identical, or, shorter contention window, or, the LBT mechanism more simplified, e.g., Cat2 LBT, and a length of 25us during CCA.The SRS character positions of candidate send the LBT performed by SRS Method the like use above-mentioned identical method.

Situation 4：Different candidate's SRS character position situations are configured for different UE, UE is passed Defeated SRS method.

Unlike situation 3, for situation 4, candidate's SRS character positions of different UE configurations Can occur it is overlapping, or, can partly overlap, or, it is not overlapping.

When being partly overlapped for the different UE candidate's SRS character positions configured, partly overlapping SRS character position differences UE configure different transmission broach, or, cyclic shift.It is not overlapping The different UE of SRS character positions can configure identical transmission broach, or, identical circulation Displacement, or, different transmission broach, or, different cyclic shifts.

If in addition, UE transmission SRS character position performs CCA symbols with another UE Position can solve SRS transmission position in same symbol by the way of CCA frequency domain patterns The problem of being collided with CCA execution positions, i.e. remain for it by one of SRS transmission broach is pre- His UE carries out CCA detections.That is, in a symbol, SRS and CCA pass through frequency division Mode is multiplexed.

Preferred embodiment 4

If allowing SRS without PUSCH to be transmitted in normal upstream subframe in LAA, now, If SRS character positions are still the last symbol of subframe, as " SRS without PUSCH ", " SRS with PUSCH " and " PUSCH " in same sub-frame of uplink during simultaneous transmission, In order to meet for the control requirement that LBT is performed before transmission signal in ETSI, then in configuration SRS Without PUSCH subframe, base station are signaled in the UE blank subframe by physical layer DCI Penultimate symbol, penultimate symbol are used to send SRS and perform CCA.

Another way, in configuration SRS without PUSCH subframe, change existing SRS Character position, i.e., it is revised as first symbol (" SRS in subframe from the last symbol in subframe Without PUSCH ", " SRS with PUSCH " and " PUSCH " CCA positions are transmission " SRS Without PUSCH ", " SRS with PUSCH " and the previous subframe in " PUSCH " subframe Last symbol), or, second symbol (" SRS without PUSCH ", " SRS with PUSCH " and " PUSCH " CCA positions are transmission " SRS without PUSCH ", " SRS with First symbol in PUSCH " and " PUSCH " subframe).

New SRS character positions, it can be signaled by physical layer DCI to UE, or, pass Defeated SRS without PUSCH subframe position is implicit to determine SRS character positions.Wherein, transmit SRS without PUSCH subframe position can be that cell-level is shared.Physical layer DCI signalings, Including：The proprietary DCI signalings of UE (for example, the signalings of format 0/4)；Or public DCI signalings (for example, format 1C)；Or group DCI signalings (for example, format 3/3A)；Or DL grant (for example, format 1A/2B/2C) signaling.

This preferred embodiment is to be based on supporting broadband SRS in LAA systems, there is provided one kind is in SRS bands Wide configuration parameter C_SRSWhen >=2, meet in ETSI on bandwidth control requirement solution method.

Wherein, in ETSI for bandwidth control requirement be：Transmission equipment is enterprising in unauthorized carrier wave The bandwidth of row transmission at least accounts for the 80% of total bandwidth.

For SRS, the transmission bandwidth on unauthorized carrier wave must similarly be fulfilled in ETSI on The control requirement of bandwidth.In existing LTE protocol, only SRS band width configurations parameter C_SRSFor 0,1,2 Meet that the transmission bandwidth in ETSI accounts at least 80% control requirement of total bandwidth.But work as SRS bandwidth Configuration parameter C_SRSThe pipe in ETSI on bandwidth is unsatisfactory for more than the SRS transmission bandwidth corresponding to 2 System requires.

Based on this, for SRS band width configuration parameters C_SRSDuring more than 2, meet that transmission band occupation is total The method of the requirement of bandwidth at least 80% is as follows：

Method one：The method that N is repeated on frequency domain.

SRS bandwidth is determined according to Bsrs and Csrs, so that it is determined that the number repeated on frequency domain, or Person, number of repetition are signaled by high-rise RRC or physical layer DCI.For example, B_SRS=0, C_SRS=6 A width of 48 PRB of SRS transmission band of determination, then it is 2 to correspond to the number repeated on frequency domain.Figure 11 It is that frequency domain according to the preferred embodiment of the invention repeats the schematic diagram that N meets ETSI control bandwidth requirements, As shown in figure 11.

According to high-rise RRC signaling or the frequency domain starting point of physical layer DCI signal deployments, start to map SRS Sequence.If the repeating mapping SRS sequences in the resource less than 80% bandwidth.

Method two：Increase the length of SRS sequences, until specified in control at least 80% correspondence Bandwidth.

Method three：Increase transmission broach Comb method.Establish transmission broach Comb and SRS Corresponding relation between transmission bandwidth.

Wherein, it can be 2,4,6,8,12 etc. to transmit broach Comb.

Method four：Change subcarrier spacing.Carried for example, corresponding to different sons according to different SRS bandwidth Wave spacing.

Assume that subcarrier spacing is r, corresponding SRS bandwidth=r*12*Msrs>=80% system bandwidth. Wherein, Msrs is PRB corresponding to SRS bandwidth

Method five：Meet that nominal bandwidth meets total bandwidth extremely in a period of time using Frequency Hopping mode Few 80% control requirement.Frequency Hopping mode and existing LTE technologies are always identical, and difference exists In the time domain interval of frequency hopping is revised as symbol level from sub-frame level.I.e. in descending burst tail portions molecule Remaining symbol in frame, or, the SRS time-domain symbols position of candidate, or, the SRS of configuration is only In defeated subframe of writing a biography, SRS Frequency Hoppings are according to symbol successively frequency hopping.

Method six：The mode to be interweaved using RB.

For example, Bsrs=0, Csrs are configured to 6 or 7, RB corresponding to its SRS bandwidth is 48. Then can be by interpolation RB method, i.e., according to frequency domain starting point, according to 96mod2, (2 be RB's Interval) for SRS is mapped corresponding to 0 or 1 in resource, but according to original comb in each PRB Mapping.

Method seven：By the way of block interleaving.

For example, Bsrs=0, Csrs are configured to 3, RB corresponding to its SRS bandwidth is 72.Cluster Number can be 2,3,4,6,8,9,12,24, and RB numbers are respectively 36 in corresponding cluster, 24,18,12,9,6,3.Figure 12 is utilization block interleaving mode according to the preferred embodiment of the invention Meet the schematic diagram of ETSI control bandwidth requirements, as shown in figure 12.

Embodiment 6

The present embodiment is provided under a kind of more subframe scheduling scenes, and processing user equipment (UE) transmission signal is not The method of continuous problem.

For PUSCH, notation index is 1 to proceed by transmission situation from subframe, blank in subframe Symbol be subframe in notation index 0.And/or PUSCH enters since subframe notation index 0 Row transmission, PUSCH terminating symbols index are 12, or, 11 situations, blank character is in subframe Notation index is 13 in subframe, or, 12 and 13.

PUSCH starts character position, or, terminating symbol position, and/or, the symbol that LBT is performed Position can by base station by physical layer DCI signal deployments to UE.

Based on this, when UE1 is scheduled in continuous multiple subframes, for example, subframe #n, subframe #n+1, and the starting point of progress PUSCH transmission is symbol 0 in subframe, end position is symbol 12 In the case of, there is transmission letter when carrying out PUSCH transmission on subframe #n, and subframe #n+1 in UE Number non-continuous event, because UE does not carry out signal transmission in subframe #n last symbol. It is before and after the situation of symbol 0 similarly appears in for the hollow white symbol of subframe in more subframe scheduling scenes Occurs transmission signal non-continuous event between subframe.

The method for solving the signal discontinuous problem occurred in more subframes is as follows：

Method one：Implicit indication UE performs LBT at the blank character between front and rear subframe.LBT can To use 25us Cat2LBT mechanism, or, similar DRS LBT mechanism, or, with Machine selects the Cat2LBT mechanism of CCA starting points, or, minimum competition window is used as 0, it is maximum competing It is the Cat4LBT mechanism that n is 0, or 1 in 5, defer period to strive window.Wherein, defer period It is that n slot is added by fixed CCA durations.Slot is 9us, a length of 16us when fixing CCA.

Method two：It is explicitly indicated at the blank character between front and rear subframe and is held by physical layer DCI signalings Row LBT.Wherein, the character position that PUSCH transmission starts can be indicated in physical layer DCI signalings, And/or PUSCH transmission terminating symbol position, and/or, blank character position in subframe, and/or, LBT mechanism, and/or, parameter corresponding to LBT mechanism, e.g., maximum contention window and minimum competition window It is worth, random back value, n values in defer period, CCA duration durations, CCA duration Starting point.

Method three：UE sends sparse preserved signal or occupancy at the blank character between front and rear subframe Signal.Sparse preserved signal or Seize ACK message refers to preserved signal or Seize ACK message only in specific frequency Sent in domain resource (RE or RB or RBG or subband).Except specific frequency domain in blank character Part or all of frequency domain resource outside resource can be used for other UE and perform CCA, in CCA successes In the case of carry out PUSCH transmission and/or SRS and send.Wherein, for performing CCA frequency domain Blank resource location and/or time-domain symbol position can be logical by physical layer DCI signalings dynamic by base station Know to UE.

Preferred embodiment 7

This preferred embodiment mainly provides cycle SRS and aperiodic SRS transmission method.

Cycle of SRS transmission and offset parameter in the case where being configured by high-rise RRC signaling, by In upstream or downstream buffer states, the opportunistic downlink or uplink that LAA is performed is transmitted, so that There is non-continuous event in transmission signal.Based on this, it is preferable that only when UE SRS periodic points it Preceding execution LBT success, and when having PUSCH on the SRS periodic points, UE could be in the SRS cycles SRS transmission is carried out on point.Preferably, only when UE performed before SRS periodic points LBT into Work(, UE cans carry out SRS transmission on SRS periodic points.Preferably, even if UE is in SRS LBT successes are performed before periodic point, SRS transmission can not be carried out on SRS periodic points, only It could attempt to carry out SRS biographies on the periodic point in SRS after the triggering of physical layer DCI signalings is received It is defeated, wherein, physical layer DCI signalings triggering SRS transmission can be that triggering UE carries out a SRS Transmission, or, n times SRS transmission.The increase triggering SRS transmission i.e. in physical layer DCI signalings Field, and/or, increase instruction SRS transmission time field.N is the positive integer more than or equal to 1. Preferably, N 1,2,3,4,5,6,7,8.Further, periodic points of the UE in SRS It is upper to attempt to carry out SRS transmission to refer to perform LBT successes before SRS periodic point, just can be It is transmitted on SRS periodic points.If failing conversely, performing LBT before SRS periodic points, It can not be transmitted on SRS periodic points.

The subframe position of SRS transmission, in addition to it can be configured by high-rise RRC signaling, Physical layer DCI signal deployments can also be passed through.Wherein, physical layer DCI signal deployments SRS is passed through The subframe position of transmission or the SRS transmission subframe position of candidate, can pass through one below mode：

Mode one：Carried in physical layer DCI signalings subframe position for indicating SRS transmission or The field of the SRS transmission subframe position of candidate.UE is by receiving DCI signalings, you can knows biography Defeated SRS subframe position or the subframe position of candidate.

Mode two：The field for indicating specific timed-shutoff set occurrence k is carried in physical layer DCI signalings. The subframe position of SRS transmission or time domain of candidate can be determined by specific timed-shutoff set occurrence Frame position.For example, physical layer DCI signalings are sent on subframe n, by receiving DCI signalings And the specific timed-shutoff set occurrence carried, determine time domain that subframe corresponding to n+k is SRS transmission Frame position or the subframe position of candidate.Wherein, k can be the value more than or equal to 0, can also For the value more than or equal to 4, it is preferable that k 0,1,2,3,4,5,6,7,8.

Mode three：The cycle of high-rise RRC signaling configuration and offset, only receive base station hair in UE During the physical layer DCI signalings sent high level RRC signaling configure cycle and offset corresponding to time domain son At least one of frame position or candidate's subframe position come into force, or, available.Wherein, physical layer Instruction SRS can be carried in DCI signalings once to be transmitted in the subframe of candidate, Huo,Duo The configured information of secondary transmission.

In addition, the subframe position of SRS transmission or the SRS transmission subframe position of candidate can be by hidden The mode contained determines, for example, receiving public DCI signalings, you can knows that SRS can be in up biography First subframe in defeated burst, or, transmit even subframe corresponding to subframe index or strange in burst Being transmitted in several subframes (can be by by subframe quotation marks correspondence or uplink burst length Interior subframe numbers mod p obtain 0,1,2 ... subframe corresponding to one of p-1 be SRS time domains son Frame or the SRS subframes of candidate), or, DRS subframes, or, descending tail portion subframe. Wherein, those time domains of which symbol or candidate accord with SRS subframes or the subframe of candidate SRS transmission is carried out on number to be signaled by physical layer DCI, or, high-rise RRC signaling Configuration, or, base station and UE make a reservation in advance, or, predefined mode determines.Wherein it is determined that SRS Time-domain symbol or the DCI signalings of candidate's time-domain symbol position, and, determine SRS subframes position Or the signaling of candidate's SRS subframes position, and, the signaling for triggering SRS transmission can be same Individual DCI signalings, or, different DCI signalings.

Alternatively, the DCI format that the signaling of SRS transmission can be multiplexed in existing protocol are triggered 0/4/1A/2B/2C/2D, wherein, for SRS and PUSCH situations, triggering SRS transmission can be with Using DCI format 0/4.And for SRS not with PUSCH situations, triggering SRS transmission can be with Outside DCI format 2B/2C/2D, DCI format 1C, or, DCI format can also be used 3/3A.Wherein, for DCI format 1C, can be passed using reserved bit to indicate to trigger SRS It is defeated.For DCI format 3/3A, the field for indicating triggering SRS transmission can be increased newly.Base In this, the subframe position of SRS transmission or time domain of candidate are also increased newly in DCI format Frame field, and/or, increase the time-domain symbol of SRS transmission or the time-domain symbol field of candidate newly, and/or, Newly-increased triggering SRS carries out single transmission or the field being transmitted several times, and/or, increase timed-shutoff set occurrence newly k。

For aperiodic SRS transmission, the signaling of aperiodic SRS transmission is triggered except triggering SRS is passed It is defeated, it is alternatively possible to carrying triggering UE carries out a SRS transmission, or, n times SRS is passed It is defeated.In addition, the SRS periodic points that the time-domain position of aperiodic SRS transmission configures except high-rise RRC Outside, can also by the subframe positions of physical layer DCI signaling dynamic instruction SRS transmissions or The subframe position of candidate.

Whether SRS transmission can be carried out on the subframe position of candidate, depending on physical layer DCI Signaling triggers and/or LBT results.The triggering of DCI signalings refers to that triggering SRS is transmitted, and/or, Triggering UE is to carry out a SRS transmission in the subframe of candidate, or, it can carry out repeatedly SRS transmission.

I.e. on the SRS subframes position of candidate, if time domain of UE candidate wherein LBT successes are performed before frame, it is possible to carry out SRS transmission on the subframe position of the candidate. Or

If performing LBT successes before the subframe of a UE candidate wherein, but do not receive The DCI signalings that base station is sent, can not be in time domain even if UE has performed LBT successes SRS transmission is carried out on frame.Or

If performing LBT successes before the subframe of a UE candidate wherein, and receive base station The DCI signalings of transmission, then according to SRS transmission of the carry out indicated in DCI signalings, still, Multiple SRS transmission information, SRS transmission is carried out on multiple SRS subframes positions of candidate.

Wherein, if multiple SRS transmission time-domain positions of candidate are continuous in time domain, once A SRS transmission time-domain position performs LBT successes to UE before wherein, you can in follow-up candidate SRS transmissions are directly carried out on SRS time-domain positions, without performing LBT.And if candidate's is more Individual SRS transmission time-domain position is discrete in time domain, once then a SRS is passed UE wherein LBT successes are performed before defeated time-domain position, that is, are only capable of being transmitted on current SRS time-domain positions. To be transmitted on follow-up candidate's SRS time-domain positions, it is necessary to carry out one of following operation：One It is to perform LBT mechanism.Second, send sparse preserved signal or Seize ACK message.Sparse reserved letter Number or Seize ACK message refer to only in total bandwidth to send preserved signal or occupancy in specific frequency domain resource Signal, remaining frequency domain resource are vacant or reserved.Reason for doing so is that in front and rear SRS time domains position Between putting the UE transmit signal be it is discontinuous, so as to cause front and rear SRS time-domain positions it Between blank character or subframe at lose channel the right to use, based on this, in front and rear SRS time-domain positions Between blank character or subframe at, or UE need send Seize ACK message, or need perform LBT.

Here the processing method that SRS transmission is carried out on the subframe of multiple candidates, it is similarly suitable For carrying out the situation of SRS transmission on the time-domain symbol position of multiple candidates.

Wherein, the subframe of SRS transmission can be descending tail portion subframe, or, DRS Subframe, or, sub-frame of uplink in uplink burst, or, first in uplink burst At least one of subframe.Further, SRS is carried out on remaining symbol in descending tail portion subframe The time-domain symbol position of transmission can by physical layer DCI signal deployments, and/or, high-rise RRC letter Order configuration, and/or, determined according to remaining number of symbols is implicit, and/or, base station and UE are prior about Determine mode to obtain.And transmit and refer in DRS subframes for SRS, SRS can be in DRS subframes In be transmitted at least one of remaining two symbols.

Physical layer DCI signalings include：The proprietary DCI of UE (for example, DCI format 0/4) or, DL grant (for example, DCI format 1A/2B/2C/2D) or, common DCI are (for example, DCI Format 1C) or, group DCI (for example, DCI format 3/3A), i.e., in physical layer DCI signalings At least one of in increase SRS field, and/or, SRS trigger fields, and/or, SRS symbol Number field, and/or, timed-shutoff set occurrence, and/or, distinct symbols number and SRS transmission time-domain symbol Indication field is indexed in position correspondence related table.

It should be noted that above-described embodiment or preferred embodiment, are not limited only to apply in downlink transfer Tail portion subframe situation, uplink tail portion subframe is can be used for, or, uplink Beginning subframe, or, uplink complete subframe, or, descending complete subframe situation, or, Other scenes (for example, the scene such as LAA, SDL, SUL, LAA DC, NB-IOT, MTC), Or other situations.

By above-described embodiment and preferred embodiment, solves descending tail portion to a certain extent SRS transmission problem in the case of remaining symbol is more in subframe.Meanwhile also increase SRS biographies Defeated chance, improve SRS capacity.It is unsatisfactory in addition, also solving particular configuration in the SRS of broadband The problem of control in ETSI on bandwidth requires.
