It is noted that the method that the equipment provided due to the present embodiment can realize above-described embodiment three, Therefore other operate the corresponding contents that may refer to embodiment three in detail, do not repeat them here.

Below by several application examples, said method is illustrated.

Application example 1

UE assists base station to compete the overall flow of unauthorized carrier wave and data transmission as shown in Figure 5.Concrete bag Including UE assists own base station to carry out seizing of unauthorized carrier resource, and then after successful contention to resource, Notice peripheral base station and other UE, and carry out the process of uplink.Comprise the following steps:

Step 1, base station sends uplink scheduling authorization (UL grant), notice below UE competition to UE Information: need to assist the unauthorized carrier number of competition, subframe numbers, execution clear channel assessment (CCA) (Clear Channel Assessment, is called for short CCA) initial time position, any block of competing on unauthorized carrier wave Resource, pre-scheduling information；

Alternatively, this competition information is gone back portability operator identifier and/or with frequency multiplexing instruction etc., in order to UE carries out uplink FDM transmission.

Step 2, receives the UE of the competition information that base station sends, and performs CCA in the position specified, when Described UE carries out CCA when channel idle being detected, at once at the public resource appointed with base station in advance Or send an instruction information in appointment resource or send instruction information and data.

Step 3, competes the base station belonging to successful UE and adjacent base station and other are not competed successfully UE detects and receives on public resource or appointment resource；

Detection purpose be: for not competing successful UE, in order to know whether can with seize The unauthorized carrier wave competed to the UE multiplexing together of unauthorized carrier wave.For described base station or adjacent For base station, in order to judge whether it is that subordinate UE robs and accounts for unauthorized carrier resource or whether can use non- Authorize carrier resource.Specifically, for UE own base station, in order to know that subordinate UE is the most successful Rob the unauthorized carrier resource accounting for specifying；For neighbouring with operator base station, in order to know whether with frequency Multiplexing enables, thus is used together, by frequency division multiplexing, the unauthorized carrier resource competed and carries out data biography Defeated；For other UE, account for resource to detect whether that Shi Tong community UE robs, or multiple with frequency Rob with UE in the same carrier cell under enable and account for resource, thus judge whether this node can use and seize The most whether the unauthorized carrier resource arrived, can carry out multiuser multiplexing uplink.

For competing successfully UE own base station, public resource or appointment resource receive described instruction letter Breath, resolves information content further, if detection is the instruction information that subordinate UE sends, then it is assumed that UE The unauthorized carrier resource of detection is seized successfully and can use.If parsing is that subordinate UE sends and with frequency Multiplexing identification enables, then own base station needs to broadcast unauthorized carrier wave available information to adjacent by X2 mouth With operator base station, and carry out resource negotiation, under this base station and adjacent same operator, base station has data to send out The UE sent, the subframe after public resource or appointment resource carries out upstream data according to the resource consulted Transmission, own base station and then need to take in duration in real time at unauthorized carrier wave with base station under operator Detect and receive upstream data.If it is indicated that information is SRS signal, then base station know channel can In the case of, in addition it is also necessary to carry out the measurement of up channel according to SRS signal, the result of measurement may be used for this Data transfer or prepare for next data transfer.If compete successful UE at public resource or Specify and have sent instruction information and a upstream data in resource, then own base station is receiving in instruction information After, in the case of knowing that channel can be used, it is also performed to the reception of upstream data.

For UE side, if not competing successful UE to detect that instruction information Shi Tong community UE sends Then thinking that channel can be used, according to pre-scheduling information, on unauthorized carrier wave, these UE use frequency division multiplexing Mode carries out data transmission.If not competing successful UE to detect that instruction information is UE under same operator Send and enable with frequency instruction, then these UE can pass in the resource location consulted before enterprising row data Defeated.And the original position carried out data transmission is: first after public resource or appointment resource complete OFDM symbol or first subframe position starts.

Application example 2

As seen in figures 6a-b, public resource is with FBE (Frame Based to the time-frequency partition structure of public resource Equipment, equipment based on frame structure) LBT (Listen Before Talk, listem-before-talk) be Illustrate its possible concrete time-domain position of anticipating.According to the above-mentioned definition to public resource, its maximum magnitude is Perform first complete symbols after CCA success to terminate to next sub-frame boundary, i.e. public resource is maximum Scope may not exceed two subframes, minimum zone be perform CCA success after a complete OFDM Symbol.

Public resource schematical sections from Fig. 6 it can be seen that in time domain public resource be by one or Multiple OFDM symbol composition, i.e. least unit in public resource time domain is a complete OFDM Symbol.And the position according to different CCA position public resources changes the most therewith, performs further The position of CCA is determined by base station.

In Fig. 6Represent LBT subframe,Represent public resource,Represent descending sub frame,Table Show special subframe,Represent sub-frame of uplink.

As shown in Figure 6 a, for UE when the original position of a subframe starts to perform CCA competition, If UE performs CCA and competes moment of unauthorized carrier resource OFDM symbol complete less than Border, then UE needs to send a Seize ACK message in the residue time-domain resource of this OFDM symbol, as Instruction information, it is to avoid other UE of native system or different system (such as Wi-Fi system) node (STA) Seize this unauthorized carrier wave.If UE performs CCA and competes the moment of unauthorized carrier resource precisely The border of one complete OFDM symbol, for above-mentioned two situations, the original position of public resource is all From the beginning of UE performs first complete OFDM symbol original position after CCA competes resource, root Send the size and determining of content (instruction information or instruction information and data) according to UE and take one or the most Individual OFDM symbol.

As shown in Figure 6 b, public resource can also divide according to frequency domain.Its public resource is successful execution CCA takies the resource of bandwidth or by multiple subcarriers on frequency domain after competing unauthorized carrier resource The one or more Physical Resource Block PRB constituted, time domain at most can take execution CCA continuously The next subframe of frame terminates.

Public resource be mainly used for send notification signal so that base station and do not compete successful UE public Detect and receive this notification signal in resource altogether, in order to obtain the situation that takies of unauthorized carrier wave, reduce base The loss that real-time blind check of standing brings.

Application example 3

Fig. 7 for specify resource schematic diagram, as shown in Figure 7, it is intended that for transmission notice base station and other The resource of UE be according to UE perform CCA position depending on, it is intended that resource always in successful execution After CCA, first OFDM symbol starts to this sub-frame boundary.

The position of CCA is performed in the beginning situation of a subframe for UE, it is intended that resource (as PUSCH) as shown in Figure 7a.If the position of execution CCA is at the end of a subframe, then specify money Source is the PUSCH resource in next subframe, as shown in Figure 7b.It is to say, successful contention is to non- The UE authorizing carrier resource can send an instruction information or instruction information sum in the resource specified According to, it being used for notifying base station and other UE, which unauthorized carrier wave has been preempted.Optionally, notice institute Belong to base station and carry out upstream data reception.Equally, base station and other UE also can be in the resource specified detections up This instruction information.Specify resource effect the same with the effect of public resource, be all to refer to as a transmission Show the transport vehicle of information.

Application example 4

This example is mainly discussed in detail the generation process performing the instruction information that the successful UE of CCA sends. Mainly introduce two kinds of instruction information generating modes: one is by normal in amendment LTE PHY Basic sequence generate required instruction information.The second is to define the indicator sequence that UE sends.

The first process obtaining required instruction information by amendment basic sequence is as follows:

After competing unauthorized carrier wave for UE side, the instruction information of transmission may include that SRS (detection Reference signal), PSS/SSS (main synchronizing sequence/secondary synchronization sequences) and Preamble (leading) etc., These signals are all by basic sequenceObtain through certain process.Therefore main detailed description is satisfied sends out The sequence sent is carried Cell ID, operator identifier and the basic sequence with information such as frequency multiplexing instructionsRaw One-tenth process.

Basic sequenceSend the original series of instruction information for UE side, wherein have N number of packet, u table Show group number u ∈ 0,1 ..., N-1}, v are the basic sequences number in group.Sequence group number u is determined by following formula:

Time slot n_sInterior sequence set sequence number u is redirected pattern f by group_gh(n_s) and sequential shift pattern f_ssObtain, i.e. U=(f_gh(n_s)+f_ss) mod N, give f here_gh(n_s) and f_ssNew generating mode, if needing in sequence to take Band Cell ID identifies the most original group and redirects switch open, represents that cell ID instruction is opened in this example, As described in following formula:

Wherein, the initialization value of pseudo-random sequence c generates with Cell ID value, is:WhereinFor cell ID.

And further, sequence needs additionally carry operator identifier and then can obtain according to the following equation :

For PUCCH, f_ssCan obtain with Cell ID and N mould, be: WhereinFor cell ID.

For PUSCH, sequence can be carried Cell ID and operator identifier, so f_ssCan by under Formula obtains:Wherein △_ssFor operator identifier, △_ss∈ 0,1 ..., m}, m For operator's number, operator identifier can be known by base station.

For SRS,WhereinFor cell ID.

Described parameter can be differently configured with flexible configuration, and the information carried in indicator sequence is the most different.Enter One step, if the indicator sequence sent needing carry with frequency Warning Mark (0 or 1), can be used this The sequence generated is scrambled and a new sequence by individual mark.

Specific in the present embodiment, above-mentioned middle N preferably takes 30, so can continue to use value in standard, but It is not limited to this value.According to domestic three common big operators, value is 3 to m.Method one is not change Being replaced on the basis of former formula framework, therefore standardization effort amount is minimum.

Method two: define an indicator sequence.Detailed process is as follows:

Assuming that number is m in UE ID set, i.e. { a₀,…,a_m-1, in Cell ID set, number is n Individual, i.e. { b₀,…,b_n-1, in operator collective, number is p, i.e. { c₀,c₁,…c_p}.Optionally, it is assumed that with Frequently multiplexing identification 0 or 1.According to the different permutation and combination of the element in these three or four set, available M*n*p or m*n*p*2 sequence.The most each sequence represents a kind of permutation and combination method.Such as: sequence Row 0 identify UE ID=a₀, Cell ID=b₀, operator ID=c₀, with frequency multiplexing identification 0, the like. Depending on the length of custom list is according to amount of bandwidth.

The value of m, n, p does not limits, and preferred p can value be 2.

Above two method, according to concrete instruction information needs the content carried different and can be suitable Modify.The above-mentioned information carried is only for example, and can be not limited to above-mentioned in other embodiments The information carried.

Application example 5

This example mainly describes in detail after UE competes unauthorized carrier resource, sends the finger described in a upper example Show that information notice base station and other UE oneself have seized successful carrier wave and the concrete mistake carried out data transmission Journey, concrete step is as described below:

Step one, performs CCA for UE side, base station triggers or the UE specified on unauthorized carrier wave Detection operation；

Here, the UE that base station triggers participates in competing on unauthorized carrier wave is included in the predefined cycle ginseng The UE, the UE receiving UL grant that compete with unauthorized carrier wave or by Paging (paging) message The UE etc. triggered.These UE can detect on the CCA position of base station notice, and for difference Frame structure, perform the position of CCA and number be different from.For FBE, perform the position of CCA Can be at the beginning of a subframe or subframe end position.For LBE (Load Based Equipment, Equipment based on load), position in subframe, the position of execution CCA is uncertain, and CCA Number the most indefinite.These can be configured by base station side.

Here, for FBE, the position that above-mentioned UE performs CCA is identical, so there will be these UE competes the unauthorized carrier resource situation that base station is specified simultaneously.And for LBE, due to each UE The random back value generated is different, the most only there will be a final successful contention of UE unauthorized to specify Carrier wave.

Step 2, competes successful UE in step one, send and seize on public resource or appointment resource The instruction information notice base station of the unauthorized carrier wave of success and other UE, or transmission instruction information and UE are certainly The upstream data of body.

Public resource described here or appointment resource are the resource introduced in example 2 and example 3, herein No longer carry out repeated description.UE send instruction information can be SRS, Preamble, PSS/SSS or Sign etc..Preferably sending SRS signal, corresponding sequence generating mode refers to example 4.

Illustrate and compete successful UE transmission instruction letter on the public resource of definition or appointment resource Breath or instruction information and data.For FBE structure, described in step one, it is possible that many Individual UE competes the situation of unauthorized carrier wave simultaneously, and for this situation, these UE are in the public money of definition By the way of time-division, frequency division or code division, instruction information or instruction letter is carried out on source or appointment resource Breath and the transmission of data.For LBE, perform CCA every time and only have a UE successful contention to resource, This UE can public resource or specify send in resource an instruction information or instruction information and self Data.

Step 3, this base station and neighbouring base station and do not compete successful UE all at public resource or refer to Determining to detect and receive instruction message in resource, this base station is also performed to the reception of upstream data.

This base station receives this instruction message on public resource or the resource specified and (could be for notice Or the instruction information measured) or indicate message and data, during resolving, base station solves The data failure that code UE sends, then base station can only understand subordinate UE success by the message received The unauthorized carrier wave that competition is arrived.Now, there are two kinds for the treatment of methods base station: the first is by subordinate UE's Schedule information sends.For the unauthorized carrier resource allowing the UE having data to send in this community arrive in competition Enterprising line frequency divides multiplexing transmission data.UE side needs after receiving the schedule information that base station sends, ability Corresponding resource carries out uplink.The second is the n-th subframe before UE performs CCA Issued uplink scheduling information, UE compete resource time be engraved in n+k (k≤4) subframe before, Base station starts to receive the data sent from UE side in the n-th+k subframe.As long as at public resource or refer to Determine to receive in resource unauthorized carrier resource can UE in n+k subframe, all begin through time-division, frequently Divide or the mode of code division carries out transmitting uplink data.

If it is indicated that the same frequency multiplexing function carried in information is opened, i.e. carry with frequency multiplexing instruction, then Base station need by X2 mouth broadcast notice neighbouring with other communities under operator can unauthorized carrier wave Resource, and hold consultation realize UE under different districts data transmission.If do not made with frequency multiplexing function Can, only in this community, UE can carry out the transmission of data by multiplex mode, and then base station is then taking The upstream data that subordinate UE sends is received in channel duration.

Additionally, neighbouring different operators base station receives this instruction message, i.e. think that this unauthorized carrier wave is Through occupied, stop detecting.

For not competing successful UE, public resource or appointment resource detect instruction information, resolves Its Cell ID judge whether be same community or carry in resolving whether instruction information operator identifier and With frequency multiplexing instruction.If not competing successful UE to parse instruction information and carry the Cell identical with self ID, then this UE thinks that specific unauthorized carrier wave can be used, at public resource or specify after resource first In subframe or performing after CCA detects that the UE of channel idle has sent its data, those can be just Really parse channel can UE can carry out transmitting uplink data by the way of frequency division multiplexing.If not Competing successful UE, to parse the Cell ID carried in instruction information different from self, but operator identifier The same and enable with frequency multiplexing, then these UE it is believed that on specific unauthorized carrier wave resource can use, and According to being about scheduled on public resource or specifying after resource in first subframe or letter detected performing CCA After the idle UE in road has sent its data, those can correctly parse channel can UE can pass through The mode of frequency division multiplexing carries out transmitting uplink data.If not competing successful UE can not parse instruction letter Cell ID, operator identifier and same frequency multiplexing instruction in breath, then these UE think that channel is unavailable.

For resolving the incorrect UE of instruction information, can process by the following method:

First method: abandon detecting on public resource or appointment resource, but at channel occupancy Channel Detection is carried out in real time in phase.Mainly in carrying out data transmission on the unauthorized carrier wave competed UE, the situation that data transmission in advance is complete, channel resource utilization ratio can be improved further.

The channel occupancy phase starts to calculate from performing CCA successful UE transmission Seize ACK message.This UE is at letter Road takies can carry out a data transfer, in the channel occupancy phase in the public resource in the phase or appointment resource Unauthorized carrier resource after Nei can also carry out data transmission.

Second method: directly abandon the detection of channel busy within the unauthorized carrier occupancy phase.Do so can The biggest channel resource can be caused to waste.

Application example 6

Fig. 8 is that this example is competed successful UE and sent the detailed process of SRS signal on public resource and show It is intended to；

Specific in this example, perform the Seize ACK message (such as instruction information) that the successful UE of CCA sends On the one hand being used for notifying that base station is the most successfully robbed accounts for specific unauthorized carrier wave, and another aspect is used for base station Carry out the measurement of up channel.

As shown in Figure 8, the moment started a subframe has the UE of unauthorized carrier wave competition qualification and holds Row CCA detects, if the UE participating in competition performs CCA success, but the CCA successful moment is not enough One complete OFDM symbol border, the most preferably sends a Seize ACK message.If competition arrive time Carve the border being precisely a complete OFDM symbol, then on preferred public resource after CCA SRS signal is sent by the way of frequency division or code division.It is emphasized that the SRS letter sent here Number it is not only and to play notice base station road occupying situation, be additionally operable to the up channel matter telling base station to carry out these UE Measurement, i.e. signals base measure bandwidth is much, the cycle, which subframe etc., such base station will Receive from competing the SRS signal taken for notice that successfully UE sends, measure each further UE, to channel conditions between base station, distributes suitable resource and MCS preferably to each UE.

If the position that each UE performs CCA is different, only one of which UE1 performs CCA success, And have sent the SRS information of correspondence.Do not compete successful UE2 and UE3 at public resource or to specify Receive and detect the Seize ACK message that UE1 sends in resource.If UE2 receives and detects that UE1 sends Signal in the Cell ID that carries identical with self, then UE2 sends self SRS letter on public resource Number, i.e. channel conditions between it and base station of notice base station measurement.And the Cell ID that UE3 detects and self Difference, but detect and Seize ACK message carries with frequency multiplexing instruction and enable, i.e. UE1 and UE3 is same The UE of the different districts under operator, then UE3 also sends the SRS letter of self equally on public resource Number.Whereas if UE2 and UE3 can not correctly resolve Seize ACK message, then UE2 and UE3 or put Abandon reception, it is believed that this carrier wave is unavailable, stop detection.Within the unauthorized carrier occupancy phase, one is straight The idle condition of row detection channel.

The most always on public resource the base station of detection it is known that the channel conditions of other UE, it is simple to According to the channel measurement information reported, issue suitable MCS grade, improve transmission quality.

In order to avoid the website of different system entered within the time that base station and other UE detection receive instruction information Row resource is seized, and the UE competed can repeat to send Seize ACK message always.

Application example 7

Fig. 9 is that this example uses D2D mechanism to realize UE and notify the schematic diagram of other nodes.

Use D2D mechanism, it is assumed that base station side specifies correspondence can in advance all UE on unauthorized carrier wave Resource, have preferable X2 interface between this base station and neighbor base station and synchronize preferably, not compete successfully UE detects on channel (PSSCH) detecting carrier wave busy just to get started at D2D to share.

As it is shown in figure 9, in all UE participating in competition, UE1 is successful in t on unauthorized carrier wave Competition is to unauthorized carrier wave, and now, UE1 will authorize transmission in the corresponding resource of PSSCH on carrier wave The instruction information of agreement in advance, so, other UE (such as UE2, UE3) just can receive on PSSCH To this sequence, thus stop this carrier wave is carried out CCA detection.Meanwhile, this base station and adjacent base station are also The instruction information of agreement can be detected in PSSCH resource.Since so, UE1 just accounts for the most successfully robbing The message informing of this unauthorized carrier resource gives other base stations and UE.Meanwhile, successful UE1 is competed Also need on unauthorized carrier wave, send one for representing channel occupied instruction information, it is to avoid other Node is seized.

It should be noted that the PSSCH resource in D2D is permissible in each subframe and each time slot Flexible configuration.

Do so, it is also possible to solve multiple UE and rob the situation accounting for same unauthorized carrier wave simultaneously.Because Can there is oneself independent resource at each UE of PSSCH, thus without producing conflict, considerably increase Base station be correctly decoded efficiency.So that base station obtains available unauthorized carrier information.
