Description

A kind of method of sending and receiving of subframe, base station and user equipment

Technical field

The present invention relates to fields of communication technology more particularly to a kind of method of sending and receiving of subframe, base station and user to set It is standby.

Background technique

Unlicensed spectrum (English: Unlicensed Spectrum) refers to common frequency spectrum, and any organization or individual is It can be used.But (English: Listen Before Talk, abbreviation: LBT) is sent out afterwards using needing to follow when unlicensed spectrum first to listen Mechanism, i.e. communication equipment first listen to whether have other communication equipments sending data on channel before sending frame, if Channel idle, the communication equipment can transmit data；Otherwise, which wouldn't send data, but when avoiding one section Between after attempt again.Usual LBT needs to follow clear channel assessment (CCA) (English: Clear Channel Assessment, abbreviation CCA) principle and extension clear channel assessment (CCA) (English: Extended CCA, abbreviation: ECCA) principle, so-called CCA principle is communication Equipment needs the time span of at least one CCA observing time window of monitor channel, wherein when CCA observing time window is scheduled Between length, such as 20 microseconds (unit: us), if communication equipment does not listen to carrier wave in this CCA observing time window Signal, then it is assumed that this channel can be used for idle channel.If communication equipment listens in this CCA observing time window Carrier signal, then it is assumed that this channel is occupied, to be transferred to the ECCA stage.An integer can be generated in ECCA phase communication equipment Then random number R needs that the channel could be used in a channel idle point after continuously listening to R CCA observing time window.

Base station can dispose LTE carrier wave in unlicensed spectrum, but because after the competition to unlicensed spectrum resource of base station only A period of time (such as: 10 milliseconds) can be used, just cannot make after other communication equipment occupies the unlicensed spectrum resource With, therefore unlicensed spectrum can not stand alone as user equipment (English: User Equipment, abbreviation: UE) service, it can only conduct One secondary carrier provides data transport service for UE, and UE needs in addition to be anchored on an authorization frequency spectrum.

In long term evolution (English: Long Term Evolution, abbreviation: LTE) system, multi-transceiver technology such as Fig. 1 institute Show, timing relationship having the same between multiple member carriers, i.e., the frame boundaries and subframe number of major-minor carrier wave are all the same；It is major-minor The uplink feedback information of the downlink data of carrier wave is sent from one of carrier wave uplink, for example, main carrier is in son in Fig. 1 The affirmative acknowledgement (English: Acknowledge, abbreviation: ACK) sent on frame 5 is to the data sent in major-minor carrier wave subframe 1 Response；The data of one carrier wave can be by the Physical Downlink Control Channel (English: Physical Downlink of other carrier waves Control Channel, referred to as: PDCCH) dispatch, i.e., cross-carrier scheduling can also be dispatched, example by the PDCCH of the carrier wave itself Such as, in Fig. 1, carry out the data in cross-carrier scheduling secondary carrier subframe 0 using the PDCCH in main carrier subframe 0, but need to pay attention to , while one of scheduling mode can only be selected.

Frame structure in LTE system as shown in Fig. 2, a frame includes 10 subframes, each subframe include at least PDCCH and Physical Downlink Shared Channel (English: Physical Downlink Shared Channel, referred to as: PDSCH) symbol, optionally There may also be enhancing Physical Downlink Control Channel (English: Enhanced Physical Downlink Control Channel, referred to as: EPDCCH).Usual PDCCH occupy in the time domain each subframe preceding n orthogonal frequency division multiplexing (it is English: Orthogonal Frequency Division Multiplexing, referred to as: OFDM) symbol, and n≤3, PDSCH only take up OFDM symbol after OFDM symbol where control channel and reference signal, if being configured with EPDCCH, EPDCCH can be with In the part frequency domain resource of the region PDSCH.

As shown in figure 3, after base station confirms that unauthorized secondary carrier is idle by ECC A (or CCA), this is begun to use non-to award Power secondary carrier carries out data transmission.But base station occupies the initial time after unauthorized carrier wave and sub-frame boundary is possible without It is overlapped, for example, in Fig. 3, base station occupies the initial time after unauthorized carrier wave to the time between the initial position of subframe 0 just It is an incomplete subframe.And CCA the or ECCA stage before base station occupies unauthorized carrier wave is likely to occupy a subframe In PDCCH where preceding n OFDM symbol, cause to lack PDCCH and the data of the subframe can not be scheduled, thus nothing Method carries out data transmission.

Iing is proposed in the prior art can be in the initial time after base station occupies unauthorized carrier wave to the starting of next subframe Leading (English: Preamble) is sent in imperfect subframe between position, to keep base station to the unauthorized secondary carrier institute In the occupancy of channel resource.But since leading transmission phase can not send the scheduling data for UE, will lead to from this In the secondary time for occupying unauthorized carrier wave, there is the resource of an imperfect subframe not to be available, to cause the wave of channel resource Take.

In order to overcome the above technical defects, a kind of side that unauthorized secondary carrier data are sent is proposed in the prior art Method, it is believed that can be in the initial time after base station occupies unauthorized carrier wave to imperfect between the initial position of next subframe The scheduling data for being directed to UE are sent in subframe, and scheduling information corresponding to the scheduling data sent in the imperfect subframe is then It is sent in next subframe.For example, as shown in figure 4, non-using the next cross-carrier scheduling of the PDCCH in the subframe 3 of authorization main carrier Authorize the data in the subframe 2 of secondary carrier.But the data that N subframe is sent in existing LTE system are generally required in N-1 Subframe carries out coded treatment.It, can not be in the previous of first subframe since the first subframe in this method is imperfect subframe Subframe knows the number for the data symbol that first subframe can be used, this brings challenge to pre-coded data.In order to mention It is preceding to may be that data transmitted by imperfect subframe encode, base station needs to know in advance that each subframe occupies data symbol The case where, it may need unnecessarily to traverse all complete subframes so as to cause base station and be pre-processed, greatly be consumed The process resource of base station.

If the processor 902 determine the last one imperfect subframe of the unauthorized carrier wave be with first it is imperfect The splicing subframe of subframe splicing then obtains one in first imperfect subframe of the unauthorized carrier wave and its splicing subframe After coded data in TTI, the processor 902 is also used to: based on from the unauthorized carrier wave the last one is imperfect The scheduling information obtained on the PDCCH of subframe is decoded the coded data of acquisition；Alternatively, being based on from the unauthorized load The scheduling information obtained on the PDCCH of the subframe of the corresponding authorization carrier wave of the imperfect subframe of the last one of wave, to the volume of acquisition Code data are decoded；Alternatively, based on first imperfect subframe and the last one imperfect son from the unauthorized carrier wave Scheduling information is extracted on the EPDCCH of frame, the data in spliced subframe are decoded；Alternatively, being based on from described unauthorized It is obtained on the EPDCCH of first imperfect subframe of carrier wave subframe for authorizing carrier wave corresponding with the last one imperfect subframe Scheduling information, the coded data of acquisition is decoded.

If the processor 902 determines that second subframe of the unauthorized carrier wave is to splice with first imperfect subframe Splicing subframe, then first imperfect subframe of the unauthorized carrier wave and its splicing subframe on obtain a TTI in After coded data, the processor 902 is also used to: based on first imperfect subframe from the unauthorized carrier wave The scheduling information obtained on PDCCH is decoded the coded data of acquisition；Alternatively, based on from the of the unauthorized carrier wave The scheduling information obtained on the EPDCCH of one imperfect subframe and second subframe, is decoded the coded data of acquisition.

As shown in fig.10, the implementing procedure of this method is such as the embodiment of the invention provides a kind of sending method of subframe Under:

Step 1001: base station is that UE configures unauthorized carrier wave.

The unauthorized carrier wave is the secondary carrier that the base station is UE configuration.

Step 1002: the base station determines first imperfect subframe after the unauthorized carrier wave is occupied, Yi Jiyu The splicing subframe of this first imperfect subframe splicing.

For example, in practical application, base station can confirm that the unauthorized carrier wave sends data by CCA or ECCA Initial time.Specifically, the end position of CCA or ECCA is not overlapped with the boundary of subframe generally, for example, CCA or ECCA End position is at the Y OFDM symbol of X subframe, wherein Y is the positive integer less than 14.Particularly, when Y is greater than 3, It indicates that CCA the or ECCA stage occupies preceding 3 OFDM symbols where the PDCCH in X subframe, that is, will appear because lacking PDCCH and the case where can not be scheduled to the data of the subframe.

In order to using the unauthorized carrier wave it is occupied after initial time between the initial position of next subframe Imperfect subframe sends valid data, to improve the service efficiency of unauthorized carrier wave, the embodiment of the present invention proposes can should Imperfect subframe and other subframes of unauthorized carrier wave are spliced into a complete subframe.Specifically, can have but be not limited to following Two kinds of connection schemes:

Scheme one,

The base station determines that the last one imperfect subframe of the unauthorized carrier wave is to spell with first imperfect subframe The splicing subframe connect.

For example, as shown in figure 11, it is assumed that this occupy the subframe 2 on unauthorized carrier wave to totally 6 milliseconds of subframe 8 (unit: Ms the time), wherein subframe 2 and subframe 8 are imperfect subframe.Scheme one is that this is occupied to the front and back of unauthorized carrier wave Two imperfect subframes --- subframe 2 and subframe 8 are spliced into a complete subframe.

Scheme two,

For example, as shown in figure 12, it is assumed that this occupy the subframe 2 on unauthorized carrier wave to totally 6 milliseconds of subframe 8 (unit: Ms the time), wherein subframe 2 and subframe 8 are imperfect subframe.Scheme two is that this is occupied the endless of unauthorized carrier wave Sub- frame --- the front portion of subframe 3 is spliced into a complete subframe by whole subframe 2 and its latter.Then, by the latter of subframe 3 Part and subframe 8 are scheduled as imperfect subframe, wherein rear portion and this kind of PDCCH of subframe 8 to subframe 3 The scheduling problem of unappropriated imperfect subframe has mature technology in the prior art to solve, and the present invention repeats no more.

It should be noted that the base station can only select one of connection scheme simultaneously, and the base station and described UE makes an appointment using identical connection scheme.

Optionally, after the base station determines that the unauthorized carrier wave is occupied, authorization carrier wave or described non-can also be passed through It authorizes carrier wave to send secondary carrier and occupies notice to the UE, to notify this described unauthorized carrier wave of occupancy of base station described in the UE Initial time, the UE carries out the data for sending from the unauthorized carrier wave of receiving and storing from the initial time Parsing.For example, as shown in figure 13, base station is sent secondary carrier using the PDCCH in authorization carrier wave subframe 3 and occupies notice to being taken The UE of business.

Optionally, after the base station determines first imperfect subframe after the unauthorized carrier wave is occupied, may be used also It is indicated to the UE to send unauthorized carrier-wave transmission, the unauthorized carrier-wave transmission instruction is used to indicate the unauthorized carrier wave First imperfect subframe position and first imperfect subframe in for splicing data symbol length.

Step 1003: the base station encodes the data in a TTI.

Step 1004: the base station by the data after coding by first imperfect subframe of the unauthorized carrier wave and It splices subframe and is sent to the UE.

Specifically, if using the first connection scheme in above-mentioned steps 1002, i.e., the described base station determines described non-award The last one the imperfect subframe for weighing carrier wave is the splicing subframe spliced with first imperfect subframe, then institute in step 1004 State base station this can account for according to the position of first imperfect subframe of the unauthorized carrier wave after occupied and the base station With the occupancy Duration Information of the unauthorized carrier wave, determine after the unauthorized carrier wave is occupied the last one is imperfect The position of subframe, then the data after coding are passed through the symbol of first imperfect subframe of the unauthorized carrier wave by the base station Number and the symbol of the last one imperfect subframe be sent to the UE.

Wherein, the occupancy Duration Information can be configured by the base station and carry to occupy in notice in secondary carrier and sent out Give the UE, the occupancy duration that base station occupies unauthorized carrier wave every time in this case can be it is unfixed, specifically The occupancy duration determined by base station after reinform to UE.Alternatively, the occupancy Duration Information is also possible to be pre-configured In the base station side and the user equipment side, base station is occupied according to the occupancy duration of agreement every time in this case Unauthorized carrier wave.

Further, the data in a TTI after coding are placed on the first of the unauthorized carrier wave by the base station It, can also be by the number in a TTI after the coding when on the data symbol of a imperfect subframe and the last one imperfect subframe The position of first imperfect subframe and the control symbol of the last one imperfect subframe is placed on according to corresponding scheduling information It sets.Wherein, scheduling information shows the corresponding data of the scheduling information and is destined to which UE and positioned at unauthorized carrier wave The information such as in any block resource.

Specifically, can have following four method to realize the placement of scheduling information:

The first: the base station by the scheduling information of the data be placed on the unauthorized carrier wave the last one is endless On the PDCCH of whole subframe.

For example, as shown in figure 14, base station is by former and later two imperfect subframes --- subframe 2 and the subframe on unauthorized carrier wave 8 are spliced into a complete subframe, and using the PDCCH of the subframe 8 on unauthorized carrier wave, are carried on unauthorized carrier wave to dispatch Data in subframe 2 and subframe 8.Correspondingly, UE needs to solve again after the subframe 2 and the concatenation of subframe 8 on unauthorized carrier wave Code.

Second: the base station by the scheduling information of the data be placed on the unauthorized carrier wave the last one is endless On the PDCCH of the corresponding subframe for authorizing carrier wave of whole subframe.

For example, as shown in figure 15, base station is by former and later two imperfect subframes --- subframe 2 and the subframe on unauthorized carrier wave 8 are spliced into a complete subframe, and use the PDCCH of the subframe on authorization carrier wave corresponding to the subframe 8 on unauthorized carrier wave, To dispatch the data in the subframe 2 and subframe 8 that are carried on unauthorized carrier wave.

The third: the base station is imperfect by the scheduling information of the data be placed on the unauthorized carrier wave first On the EPDCCH of subframe and the last one imperfect subframe.

For example, as shown in figure 16, base station is by former and later two imperfect subframes --- subframe 2 and the subframe on unauthorized carrier wave 8 are spliced into a complete subframe, and using the EPDCCH of subframe 2 and subframe 8 on unauthorized carrier wave, are carried on non-award to dispatch Weigh the data in the subframe 2 and subframe 8 of carrier wave.

4th kind: the base station is imperfect by the scheduling information of the data be placed on the unauthorized carrier wave first On the EPDCCH of the subframe subframe for authorizing carrier wave corresponding with the last one imperfect subframe.

For example, as shown in figure 17, base station is by former and later two imperfect subframes --- subframe 2 and the subframe on unauthorized carrier wave 8 are spliced into a complete subframe, and using the subframe on authorization carrier wave corresponding to the subframe 2 and subframe 8 on unauthorized carrier wave EPDCCH, to dispatch the data in the subframe 2 and subframe 8 that are carried on unauthorized carrier wave.

In addition, if using second of connection scheme in above-mentioned step 1102, i.e., the described base station determines the unauthorized load Second subframe of wave is the splicing subframe with first imperfect subframe splicing, then base station described in step 1104 can root According to the symbol lengths M of first imperfect subframe, the splicing symbol lengths N of second subframe is determined；Wherein, this first it is endless The symbol lengths M of whole subframe include filling signal or targeting signal occupy symbol lengths, control symbol length and data The length of symbol, and the sum of M and N are the symbol lengths of a complete subframe.Then the base station passes through the data after coding The symbol of first imperfect subframe of the unauthorized carrier wave and the top n symbol of second subframe are sent to the UE.

Further, the data in a TTI after coding are placed on the first of the unauthorized carrier wave by the base station It, can also be by the volume when on the data symbol for including in the data symbol of a imperfect subframe and the top n symbol of second subframe Scheduling information corresponding to the data in a TTI after code is placed on the control symbol and second of first imperfect subframe On the position for the control symbol for including in the top n symbol of a subframe.

Specifically, can have following two method to realize the placement of scheduling information:

The first: the base station is imperfect by the scheduling information of the data be placed on the unauthorized carrier wave first On the PDCCH of subframe.

For example, as shown in figure 18, the front portion of imperfect subframe 2 and subframe 3 on unauthorized carrier wave is spliced in base station For a complete subframe, and using the preceding n OFDM symbol of subframe 2 as the PDCCH of subframe 2, using the son on unauthorized carrier wave The PDCCH of frame 2 dispatches the data being carried in 3 front portion of subframe 2 and subframe, wherein n≤3.

Second: the base station is imperfect by the scheduling information of the data be placed on the unauthorized carrier wave first On the EPDCCH of the top n symbol of subframe and second subframe.

For example, as shown in figure 19, the front portion of imperfect subframe 2 and subframe 3 on unauthorized carrier wave is spliced in base station For a complete subframe, and son is carried on to dispatch using the EPDCCH of 3 front portion of subframe 2 and subframe on unauthorized carrier wave Data in 3 front portion of frame 2 and subframe.

Further, the base station is using the top n symbol of second subframe of the unauthorized carrier wave as splicing subframe It, can also be using the rear M symbol of second subframe of the unauthorized carrier wave as new after first imperfect subframe splicing Imperfect subframe be scheduled, and the scheduling information for the data dispatched on the rear M symbol of second subframe is placed on On the PDCCH of second subframe of the unauthorized carrier wave.

For example, as shown in figure 20, the front portion of imperfect subframe 2 and subframe 3 on unauthorized carrier wave is spliced in base station It is scheduled for a complete subframe, while the subsequent remainder of the subframe 3 imperfect subframe new as one being adjusted The PDCCH as subframe 3 is vacated in the n OFDM symbol that subframe 3 originates in degree, base station, remains for dispatching to be carried on behind subframe 3 Data in remaining part point.

It optionally, can also be in the unauthorized carrier wave before the data after coding are sent to the UE by the base station Upper transmission filling signal or targeting signal are to the UE, to keep the occupancy to the unauthorized carrier wave, and described in notice UE confirmed according to the testing result to filling signal or targeting signal first after the unauthorized carrier wave is occupied it is imperfect The position of subframe.

Refering to shown in Figure 21, the embodiment of the invention also provides a kind of method of reseptance of subframe, the implementing procedures of this method It is as follows:

Step 2101:UE receives the data that base station is sent by unauthorized carrier wave.

Wherein, the unauthorized carrier wave is the secondary carrier that the base station is the UE configuration.

Optionally, the UE is before receiving the data that base station is sent by unauthorized carrier wave, it is also possible to can receive institute Stating the filling signal that base station is sent by the unauthorized carrier wave, perhaps the targeting signal filling signal or targeting signal are used In keep the base station to the occupancy of the unauthorized carrier wave and after notifying that unauthorized carrier wave described in the UE is occupied the The position of one imperfect subframe.

Specifically, the UE determines the unauthorized carrier wave by the base station by filling signal or targeting signal detection The method of first imperfect subframe after occupancy are as follows: the UE is filled signal or targeting signal to the unauthorized carrier wave Detection, the subframe confirmation that will test filling signal or targeting signal is after the unauthorized carrier wave is occupied by the base station First imperfect subframe.

And before first imperfect subframe after the UE determines that the unauthorized carrier wave is occupied by the base station, it can Selection of land, the UE are also possible to that the secondary carrier occupancy that the base station is sent by authorization carrier wave or the unauthorized carrier wave can be received Notice, the secondary carrier occupancy notice is used to indicate the base station, and this occupies the initial time of the unauthorized carrier wave.Due to UE received data can will be stored in local from unauthorized carrier wave, therefore the UE is occupied according to the secondary carrier and notified, can To confirm the orthochronous for starting to parse the data sent on unauthorized carrier wave, to parse valid data.

Step 2102: the UE determine the unauthorized carrier wave by the base station occupy after first imperfect subframe, And the splicing subframe with this first imperfect subframe splicing.

Wherein, the unauthorized carrier-wave transmission that the UE can be sent according to the base station indicates, determines the unauthorized load Wave is by first imperfect subframe after the occupancy of the base station.

For example, first imperfect subframe after being occupied with prespecified unauthorized carrier wave by the base station is to receive The previous subframe of the unauthorized carrier-wave transmission instruction.

Specifically, the embodiment of the present invention can have but be not limited to following two connection scheme:

Scheme one,

The UE determines that the last one imperfect subframe of the unauthorized carrier wave is to splice with first imperfect subframe Splicing subframe.

Specifically, the UE can be according to the position and the base station of first imperfect subframe of the unauthorized carrier wave This occupies the occupancy Duration Information of the unauthorized carrier wave, determines the last one after the unauthorized carrier wave is occupied The position of imperfect subframe, and be the unauthorized load by the subframe confirmation on the position of the last one determining imperfect subframe The imperfect subframe of the last one of wave.

Wherein, the occupancy Duration Information can be configured by the base station and carry to occupy in notice in secondary carrier and sent out The UE is given, the base station side and the user equipment side can also be pre-configured to be in.

Scheme two,

It should be noted that the UE can only select one of connection scheme, and the UE and the base station simultaneously It makes an appointment using identical connection scheme.

Step 2103: the UE obtains one in the first imperfect subframe and its splicing subframe of the unauthorized carrier wave Coded data in a TTI.

Specifically, the UE obtains one in the first imperfect subframe and its splicing subframe of the unauthorized carrier wave The method of coded data in TTI are as follows: determine the symbol lengths of first imperfect subframe and the length of data symbol first Degree calculates the length of the data symbol of splicing subframe, finally first then according to the symbol lengths of first imperfect subframe The coded data in a TTI is obtained on the data symbol in data symbol and splicing subframe in a imperfect subframe.

For example, UE obtain certain using unauthorized carrier-wave transmission data the occupancy duration (including leading/filling/ Data/control section) it is 6ms, the starting subframe for starting transmission is subframe 2, primary sign is symbol 5 in subframe 2, it is known that this Secondary UE has received 5 complete subframes and former and later two imperfect subframes altogether, and (i.e. first imperfect in subframe 2 by UE Subframe) on occupy symbol 5 totally 10 symbol lengths (including sent out in subframe 2 to symbol 14 (subframe has 14 symbols) Leading/filling/data/the control section sent).If the splicing subframe of subframe 2 is that this occupies last of unauthorized carrier wave A subframe can be confirmed that subframe 8 (i.e. the 7th subframe) is ending subframe by calculating UE, and due to son as shown in figure 11 The sum of frame 2 and the symbol lengths of subframe 8 one is set to 14 symbols, therefore total symbol lengths of subframe 8 are 4 symbols.In subframe 2 Data symbol part is included in the symbol 5 of subframe 2 between symbol 14, and the data symbol part in subframe 8 is included in subframe 8 Symbol 1 is between symbol 4.UE is needed 10 symbols of subframe 2 and 4 symbols of subframe 8 splicing one complete subframe of composition Afterwards, the character position for deducting targeting signal, filling signal and control signal carries out data decoding again later.In addition, if subframe 2 Splicing subframe be this occupy second subframe of unauthorized carrier wave, as shown in figure 12, by calculate UE subframe 3 can be confirmed Symbol lengths in (i.e. second subframe) for splicing are 14-10=4 symbol, then UE is needed preceding 4 symbols of subframe 3 It is decoded with after 10 symbols splicing one complete subframe of composition of subframe 2.Due to that may be wrapped in preceding 4 symbols of subframe 3 N control symbol is contained, n≤3, this n controls the data that symbol is sent on rear 10 symbols of scheduling subframe 3, therefore UE may need to deduct in subframe 2 and the spliced complete subframe of subframe 3 character position of targeting signal and filling signal with And deduct and carry out data decoding again after the position of this n control symbol, and the data UE carried on rear 10 symbols of subframe 3 It needs in addition to be decoded.

In the embodiment of the present invention, the UE can have following two mode determine first of the unauthorized carrier wave not The complete symbol lengths of subframe and the length of data symbol:

The first: the UE is filled the detection of signal or targeting signal to the unauthorized carrier wave, according to inspection in institute State the position that the symbol of filling signal or targeting signal is detected in first imperfect subframe of unauthorized carrier wave, calculate this The symbol that filling signal or targeting signal occupy in the symbol lengths of one imperfect subframe and first imperfect subframe Length, and the symbol lengths that are occupied according to the symbol lengths, filling signal or targeting signal of first imperfect subframe and The length for controlling symbol, calculates the length of the data symbol in first imperfect subframe；Wherein, first imperfect son The symbol lengths of frame include filling signal or targeting signal occupy symbol lengths, control symbol length and data symbol Length.

For example, it is assumed that UE detects targeting signal during S to E symbols of the N subframe of unauthorized carrier wave, In, E >=S and E, S are positive integer, then it is assumed that the N subframe be base station occupy first after the unauthorized carrier wave it is imperfect Subframe, the E+1 symbol to contained between the last symbol of the N subframe data symbol occupancy position, Huo Zheke The position that control symbol occupies can be further included.Under the first connection scheme of the invention, i.e. first imperfect subframe Splicing subframe be base station this when occupying the last one imperfect subframe of unauthorized carrier wave, the E+1 symbol is sub to the N It is the position that data symbol occupies between the last symbol of frame；And under second of connection scheme of the invention, i.e., The splicing subframe of one imperfect subframe be base station this when occupying second subframe of unauthorized carrier wave, the E+1 symbol arrives After having deducted the n position that control symbol occupies between the last symbol of the N subframe, it is only the position of data symbol occupancy It sets.

Second: the UE indicates according to the unauthorized carrier-wave transmission that the base station is sent, and determines the unauthorized carrier wave First imperfect subframe symbol lengths and the data symbol in first imperfect subframe length.

Further, the UE obtains the coded data in a TTI from first imperfect subframe and its splicing subframe Afterwards, it is also necessary to extract corresponding scheduling information and the coded data in first imperfect subframe and its splicing subframe is solved Code.

If the UE determines that the last one imperfect subframe of the unauthorized carrier wave is and the in above-mentioned steps 2102 The splicing subframe of one imperfect subframe splicing, then the UE can based on from the unauthorized carrier wave the last one is imperfect The scheduling information obtained on the PDCCH of subframe is decoded the coded data of acquisition.Alternatively, the UE can be based on from institute The scheduling information obtained on the PDCCH of the corresponding subframe for authorizing carrier wave of the last one imperfect subframe of unauthorized carrier wave is stated, The coded data of acquisition is decoded.Alternatively, the UE can be based on first imperfect son from the unauthorized carrier wave Scheduling information is extracted on frame and the EPDCCH of the last one imperfect subframe, the data in spliced subframe are decoded. Alternatively, the UE can be corresponding with the last one imperfect subframe based on first imperfect subframe from the unauthorized carrier wave Authorization carrier wave subframe EPDCCH on the scheduling information that obtains, the coded data of acquisition is decoded.

If in above-mentioned steps 2102, the UE determine the unauthorized carrier wave second subframe be with first it is endless The splicing subframe of whole subframe splicing, then the UE can be based on first imperfect subframe from the unauthorized carrier wave The scheduling information obtained on PDCCH is decoded the coded data of acquisition.Alternatively, the UE is based on from the unauthorized load The scheduling information obtained on first imperfect subframe of wave and the EPDCCH of second subframe carries out the coded data of acquisition Decoding.

In conclusion technical solution provided in an embodiment of the present invention, by the way that base station to be occupied to the starting after unauthorized carrier wave Imperfect subframe and other subframes between moment and the initial position of next subframe are spliced into a complete subframe, so that one The coded data of a complete subframe can be carried in two imperfect subframes, be can use the imperfect subframe and sent significant figure According to, the service efficiency of unauthorized carrier wave is improved, no matter and the transmission data since on which symbol of imperfect subframe, base It stands all only with the data for shifting to an earlier date precoding one complete subframe, the complete subframe without traversing all is pre-processed, saved The process resource of base station.
