902nd, the unauthorized cell sends contextual information to the UE；

If the 903, the contextual information carries nack message, the UE is to unauthorized cell retransmission data；

If it should be noted that the contextual information carries ACK information, this time going up line number According to being transmitted.

The UE is to after unauthorized cell retransmission data, the unauthorized cell regenerates contextual information according to the data of repeating transmission, if still carrying NACK control character information in the contextual information, then repeat step 902 and 903, until carrying ACK information in the contextual information, this time transmitting uplink data is completed, i.e.,

904th, the unauthorized cell sends contextual information to UE, and the contextual information carries ACK control character information.In the UE as shown in Figure 9 and the unauthorized cell carry out the interaction of a transmitting uplink data, what is do not embodied also has following process：If after step 901, if the UE does not receive the unauthorized cell by authorizing the corresponding contextual informations of the UE that cell is sent in preset time period, the UE resends the data that UE described in step 901 is sent to unauthorized cell by the mandate cell to the unauthorized cell.

In the prior art, the interaction of the UE and a unauthorized cell transmitting uplink data of progress includes：

905th, the unauthorized cell sends downlink data block to UE；

906th, the UE sends contextual information to the unauthorized cell；

If the 907, the contextual information carries nack message, the unauthorized cell is to UE retransmission datas；

If it should be noted that the contextual information carries ACK information, this time downlink data transmission is completed.

The unauthorized cell is to after UE retransmission datas, the UE regenerates contextual information according to the data of repeating transmission, if still carrying NACK control character information in the contextual information, then repeat step 906 and 907, until carrying ACK information in the contextual information, this time downlink data transmission is completed, i.e.,

908th, the UE sends contextual information to unauthorized cell, and the contextual information carries ACK control character information.A downlink data transmission is carried out in the UE as shown in Figure 3 and the unauthorized cell Interaction in, do not embody also have following process：If after step 905, if the unauthorized does not receive the UE by authorizing the corresponding contextual information of the unauthorized cell that cell is sent in preset time period, the unauthorized cell resends the data that unauthorized cell described in step 905 is sent to the UE by the mandate cell to the UE.It should be noted that, the downlink data transmission process shown in transmitting uplink data process and step 905-908 shown in step 901-904, it is not after transmitting uplink data is performed, then to perform the scheme of downlink data transmission it is to be appreciated that two processes arranged side by side.Based on shown in Fig. 9 and above description, during UE and the unauthorized cell carry out data transmission, the frequency spectrum resource of the unauthorized cell is seized, during in down state, and the communication of UE and unauthorized cell may be at following several states：The first state, the UE have sent data block to the unauthorized cell, and when not receiving the corresponding contextual information of the UE that the unauthorized cell sends, the unauthorized cell spectrum resource is changed into unavailable from available；

Second state, the UE send data block to the unauthorized cell, after it have received the corresponding contextual informations of the UE of unauthorized cell transmission, the unauthorized cell spectrum resource is changed into unavailable from available, wherein, NACK control character information is carried in HARQ feedback information in the contextual information, the NACK control characters information represents that the unauthorized base station has successfully received the data block that the UE is sent, but decoding failure；The third state, the UE have sent data block to the unauthorized cell, after it have received the corresponding contextual informations of the UE of unauthorized cell transmission, the unauthorized cell spectrum resource is changed into unavailable from available, wherein, ACK control character information is carried in HARQ feedback information in the contextual information, the ACK control characters information represents that the unauthorized base station has successfully received the data block that the UE is sent, and successfully decoded；4th kind of state, the unauthorized cell have sent data block to the UE, and when not receiving the corresponding contextual information of the unauthorized cell that the UE sends, the unauthorized cell spectrum resource is changed into unavailable from available；5th kind of state, the unauthorized cell have sent data block to the UE, after the corresponding contextual information of the unauthorized cell that the UE is sent is received, the unauthorized cell spectrum resource is changed into unavailable from available, wherein, in the HARQ feedback information in the contextual information NACK control character information is carried, the NACK control characters information represents that the UE is successfully received the data block that the unauthorized cell is sent, but decoding failure；6th kind of state, the unauthorized cell have sent data block to the UE, after the corresponding contextual information of the unauthorized cell that the UE is sent is received, unauthorized cell spectrum resource is changed into unavailable from available, ACK control character information is carried in HARQ feedback in the contextual information, the ACK control characters information represents that the UE has been successfully received the data block that the unauthorized cell is sent, and successfully decoded, it is not necessary to the unauthorized cell resends the data block.

7th kind of state, the UE have sent data block to the unauthorized cell, but be not received by within the default time the corresponding contextual informations of the UE that the unauthorized cell is sent；8th kind of state, the unauthorized cell have sent data block to the UE, but be not received by within the default time the corresponding contextual information of the unauthorized cell that the UE is sent.For in the data transmission procedure of the progress of UE and unlicensed spectrum, the either transmitting procedure of upstream data, or the transmitting procedure of downlink data, as long as data sending terminal have received corresponding contextual information, and ACK control character information is carried in contextual information, the success of this data transfer is then represented, i.e., the third and the 6th kind of communications status described above, the present invention are not covered for both states.

But, if UE and unauthorized cell are in described above first and second and the four, five and the 7th, eight kind of communications status, the unlicensed spectrum resource is unavailable, then it is unsuccessful to be likely to result in data transfer, the problem of producing the wasting of resources.Specifically,

If in the first communications status, unlicensed spectrum resource is changed into unavailable, because the unauthorized cell is without the corresponding contextual informations of the UE transmissions UE described in normal direction, cause the UE after unauthorized cell spectrum resource recovery is available, again to the unauthorized cell retransmission data, so that the problem of causing the wasting of resources；Accordingly, if in the 4th kind of communications status, unlicensed spectrum resource is changed into unavailable, because the UE is without the corresponding contextual information of the unauthorized cell transmission unauthorized cell described in normal direction, the unauthorized cell is after unauthorized cell spectrum resource recovery is available, again to the UE retransmission datas, so that the problem of causing the wasting of resources；

If in second of communications status, unlicensed spectrum resource is changed into unavailable, and the UE is without the timely retransmission data of unauthorized cell described in normal direction so that data transfer is unsuccessful, cause both it Between communication failure；

Accordingly, if under the 5th kind of communications status, unlicensed spectrum resource is changed into unavailable, and the unauthorized cell is same without the timely retransmission datas of UE described in normal direction so that data transfer is unsuccessful, causes communication failure between the two.If in seven kinds of communications status, unlicensed spectrum resource is changed into unavailable, and the UE causes communication failure between the two without the timely retransmission data of unauthorized cell described in normal direction；If in the 8th kind of communications status, unlicensed spectrum resource is changed into unavailable, and the unauthorized cell is same without the timely retransmission datas of UE described in normal direction, causes communication failure between the two.In order to avoid in described above first and second and the four, five and the 7th, eight kind of communications status, the problem that unauthorized cell spectrum is unavailable, UE and unauthorized cell can be by authorizing cell to be communicated.Based on this, the UE with unauthorized cell when being communicated, it is thus necessary to determine that whether the frequency spectrum resource of the unauthorized cell can use.When user equipment (UE) and the frequency spectrum resource of unauthorized cell are changed into disabled from can use, the U E can judge that the unauthorized cell spectrum resource is unavailable by the following method：

The UE determines that the unauthorized cell spectrum resource is unavailable by detecting：The frequency that UE can be used in unauthorized cell, the time-frequency location where oneself estimated pilot tone, monitors wireless signal, and decoded, if it is possible to be correctly decoded, and is considered as unauthorized cell and can use；If can not decode, it is considered as that unauthorized cell is unavailable, therefore, the UE can detect whether the unauthorized cell spectrum resource can use by this method.The UE receives the disabled message of unauthorized cell spectrum resource of unauthorized cell transmission to determine that the unauthorized cell spectrum resource is unavailable：The unauthorized cell is when robbing the frequency spectrum resource for accounting for unauthorized cell, the time that the frequency spectrum resource accounted for can be utilized by the unauthorized cell is robbed can calculate simultaneously described in, therefore, the unauthorized cell from that can be changed into disabled preceding L seconds by unauthorized cell spectrum resource can issue the unauthorized cell spectrum resource i.e. by disabled message in the unauthorized cell spectrum resource to the UE, wherein, L can be set according to actual conditions, and the embodiment of the present invention is not specifically limited.Therefore, the UE determines that the unauthorized cell spectrum resource is unavailable by receiving the disabled message of unauthorized cell spectrum resource of the unauthorized cell transmission, specifically, the unauthorized cell accounts for the calculating of the use time after the unlicensed spectrum resource to the unlicensed spectrum resource robbing, it is the known technology of those skilled in the art, the embodiment of the present invention is repeated no more to this； Specifically, the UE, which determines that the frequency spectrum resource of the unauthorized cell is unavailable, can use following technical scheme：

The first scheme：The UE detects whether the frequency spectrum resource of the unauthorized cell is unavailable；Specifically, during the UE uses unauthorized cell spectrum resource, monitoring wireless signal in the time-frequency location where itself estimated pilot tone, and decoded, if it is possible to be correctly decoded, then it is assumed that unauthorized cell can use；If can not decode, unauthorized cell is considered as unavailable.Second scheme：The UE can receive the disabled message of unauthorized cell spectrum resource that the base station of the unauthorized cell is sent；

Wherein, when the unauthorized cell is seized to unlicensed spectrum resource, the time that the unauthorized cell uses the unlicensed spectrum resource can be obtained.Specifically, the unauthorized cell can notify workable for unlicensed spectrum resource described in the UE period within the period；Or the unauthorized cell can notify workable for unlicensed spectrum resource described in the UE deadline within the period.

The third scheme：If the unauthorized cell is with authorizing cell not share same base station, but there is preferable return link between the unauthorized cell and mandate cell, then the UE receives the disabled message of unauthorized cell spectrum resource of the base station transmission for authorizing cell or the unauthorized cell, wherein, the disabled message of unauthorized cell spectrum resource for authorizing cell to send is that the unauthorized cell is sent.

Specifically, after the frequency spectrum resource of unauthorized cell is changed into unavailable from can use, the unauthorized cell sends the disabled message of unauthorized cell spectrum resource to the mandate cell, is sent the disabled message of unauthorized cell spectrum resource to the UE by the mandate cell.Wherein, the preferable return link refers to that the communication delay between two base stations is 0, certainly in actual application, think there is preferable return link between two base stations when can the communication delay between two base stations be less than P seconds, the P is according to depending on concrete condition, and the embodiment of the present invention is not limited this.Specifically, the mandate cell can pass through physical downlink control channel PDCCH resources or physical mixed automatic re-transmission indicating channel P H I C H resources or Physical Downlink Shared Channel resource PDSCH, or, the unauthorized cell is sent the disabled message of unauthorized cell spectrum resource to the U E by MAC entities. For 802, details are as follows：

Specifically, if the UE receives the corresponding contextual informations of the UE that the unauthorized cell is sent, the first nack message carried in the corresponding contextual information of the UE, the UE is by authorizing cell to retransmit the corresponding data of first nack message to unauthorized cell；If or the UE sends data to the unauthorized cell, the UE receives the corresponding contextual informations of the UE that the unauthorized cell is sent by the mandate cell in preset time period；Or

If the UE sends the first data to the unauthorized cell, the corresponding contextual informations of the UE that the unauthorized cell is sent are not received in preset time period, the UE retransmits the first data by the mandate cell to the unauthorized cell；Or

If carrying the second nack message in the corresponding contextual information of the unauthorized cell that the UE is sent to the unauthorized cell, the UE receives the unauthorized cell by authorizing the corresponding data of second nack message that cell is retransmitted；Or

If the UE receives the data that the unauthorized cell is sent, the corresponding contextual information of the unauthorized cell is not sent to the unauthorized cell, the U E are sent the corresponding contextual information of the unauthorized cell to the unauthorized cell by the mandate cell in preset time period；Or

If the UE has been received by the second data that the unauthorized cell is sent, failed in preset time period to send the corresponding contextual information of the unauthorized cell to the unauthorized cell, the UE receives the second data that the unauthorized cell is retransmitted by the mandate cell.The embodiments of the invention provide a kind of method of data transfer, this method includes：During user equipment (UE) and the unauthorized cell carry out data transmission, user equipment (UE) determines that the frequency spectrum resource of unauthorized cell is unavailable；The UE and the unauthorized cell are by authorizing cell to be communicated.Based on the embodiment of the present invention, it can cause when the frequency spectrum resource of unauthorized cell is unavailable, UE and unauthorized cell can be by authorizing cell to be in communication with each other, and then reduce unauthorized cell spectrum resource it is unavailable when influence to data transfer, lift message transmission rate, the availability of frequency spectrum is improved, the waste of resource is reduced.

The embodiment of the present invention additionally provides a kind of method, with reference to Figure 10, and this method is the specific descriptions to a upper embodiment of the method, including： 1001st, user equipment (UE) determines that the frequency spectrum resource of unauthorized cell is unavailable.

If the 1002, the UE receives the corresponding contextual informations of the UE that the unauthorized cell is sent, the first nack message carried in the corresponding contextual information of the UE, the UE is by authorizing cell to retransmit the corresponding data of the-nack message to unauthorized cell.Specifically, the UE can pass through the Physical Uplink Shared Channel resource PUSCH for the authorizing cell distribution or special physical uplink control channel resource PUCCH for distributing to the UE, the corresponding data of first nack message are retransmitted to cell is authorized, to cause the mandate cell to send the corresponding data of first nack message to unauthorized cell.If the UE receives the corresponding contextual informations of the UE that the unauthorized cell is sent, the first nack message carried in the corresponding contextual information of the UE, now, the UE should retransmit the corresponding data of first nack message to the unauthorized cell, but, if the UE is before the corresponding data of first nack message are retransmitted, the unauthorized cell spectrum resource is changed into unavailable from available, then the UE passes through the Physical Uplink Shared Channel resource PUSCH for the authorizing cell distribution or special physical uplink control channel resource PUCCH for distributing to the UE, the corresponding data of first nack message are retransmitted to authorizing cell, to cause the mandate cell to send the corresponding data of first nack message to unauthorized cell.

Wherein, the Physical Uplink Shared Channel resource PUSCH for authorizing cell to distribute is specially：The first situation：When unauthorized cell spectrum resource is unavailable, the PUSCH that the mandate cell is reserved to the UE mandate cells issued to the UE.Specifically, if the unauthorized cell is with authorizing cell co-sited, or the unauthorized cell is with authorizing cell not co-sited, but there is preferable return link between the unauthorized cell and mandate cell, so, after unauthorized cell spectrum resource is unavailable, the unauthorized cell sends the disabled message of unauthorized cell spectrum resource to the mandate cell, the mandate cell is that the UE reserves Q PUSCH resource, and the reserved PUSCH resources are handed down to the UE, wherein, Q is more than or equal to 1.

Second of situation：The PUSCH resources for authorizing cell to be randomly assigned to the UE.Specifically, it is described to authorize cell to send PUSCH resources at random to the user equipment in the mandate cell, the UE is after unauthorized cell spectrum resource is unavailable, the PUSCH resources that can be randomly assigned using the mandate cell are sent the corresponding contextual information of the unauthorized cell to the mandate cell, to authorize cell by the corresponding context of the unauthorized cell Information is sent to the unauthorized cell.

Wherein, the special PUCCH resource is to be configured by the mandate cell for the UE, and setup time does not limit, can be before unauthorized cell spectrum resource is unavailable, can also be after unauthorized cell spectrum resource is unavailable.The mandate cell is to be sent to the UE after the UE configures the PUCCH resource, is not repeated to send afterwards, but the reusable mandate cells of the UE are the PUCCH resource of the UE special configurations.Optionally, recognize whether the data that UE is sent need to send to unauthorized cell to authorize cell to be easy to, the corresponding data of the first NACK information for being retransmitted to the unauthorized cell can also be identified by the UE, described to identify for indicating that the data block is sent to unauthorized cell.For example, before the corresponding data of first nack message are retransmitted to the unauthorized cell by authorizing cell by the UE, the corresponding data of first nack message are increased a special mark by the UE at MAC layers, such as a special logical channel number, the special mark indicates that the data are destined for unauthorized cell, then sends the data after mark to the base station of the mandate cell by PUSCH resources or PUCCH resource.Again for example, the UE can also be by the corresponding data of the first nack message for being retransmitted to unauthorized cell in rlc layer one special mark of increase, for example, generally the particular type of the control cell is identified before control cell in existing data block with a special field, but the special field only one of which value, in embodiments of the present invention, a new value can be increased to the special field, is sent for identifying the data to unauthorized cell.

So, after authorizing cell to receive the data for the mark that the UE is sent, it can determine whether that the data should be sent to unauthorized cell if special identifier is detected, the mandate cell sends the UE data retransmitted to unauthorized cell.

Specifically, which kind of form to identify the position of special identifier and special identifier using in the data of repeating transmission, the embodiment of the present invention is not limited this.

If the 1003, the UE sends data to the unauthorized cell, the UE receives the corresponding contextual informations of the UE that the unauthorized cell is sent by the mandate cell in preset time period.

Specifically, the UE receives the corresponding context letters of the UE that the unauthorized cell is sent in preset time period by authorizing cell to distribute Physical Downlink Shared Channel resource PDSCH Breath.

Wherein, the corresponding contextual informations of the U E specifically include at least one in the following parameter：Hybrid automatic repeat-request HARQ, power headroom reporting (PHR) PHR, Slow rush state report BSR, robustness head compression ROHC, wireless spread-spectrum technology RLC state reports, PDCP

PDCP state reports.Specifically, the HARQ feedback included in the contextual information has following several forms：The first form：The H A R Q feedback informations include the corresponding HARQ process numbers of subframe numbers of each transmission block and ACK the or NACK control character information of each transmission block.For example, with reference to Fig. 1 1a, if UE respectively receives a transmission block in the subframe 5,6,7,8 of downlink radio frame respectively, the UE is according to the subframe numbers of downstream transmission blocks are received for keyword, and each subframe numbers correspond to an ACK or NACK control character information.

Second of form, HARQ information includes the corresponding HARQ process numbers of subframe numbers of each transmission block and ACK the or NACK control character information of each transmission block.For example, with reference to figure l ib, under TDD mode of operations, UE HARQ number of processes is relevant with the proportioning of TDD subframes, most 13.When sending downlink data to the UE in base station, it is notified that the UE receives data with which HARQ process, if UE respectively receives a transmission block in the subframe 5,6,7,8 of downlink radio frame respectively, it is respectively 0,1,2,12 that then the base station can send subframe 5,6,7,8 corresponding HARQ processes while transmission block is sent to the UE, then the UE is keyword according to the HARQ process numbers of reception transmission block, one ACK or NACK control character information of each HARQ process numbers correspondence；The third form, the HARQ information includes the bit map of HARQ process numbers, the bit map includes multiple bits, the value of the corresponding bit of HARQ process numbers of each transmission block is used for ACK the or NACK control character information for representing each transmission block, and the value of the corresponding bit of the corresponding HARQ process numbers of subframe without transport block transmission is sky.For example, with reference to Fig. 1 1c, the UE does not send HARQ process numbers, only send a bit map, 13 bits are included in the bit map, each bit represents 1-12 totally 13 HARQ process numbers successively, for example, HARQ process numbers receive a transmission block respectively when being 0,1,2,12, then there is the value of the corresponding bit of HARQ process numbers of transmission block to be used for ACK the or NACK control character information for representing each transmission block, other do not have the value of the corresponding bit of HARQ process numbers of transmission block to be sky； 4th kind of form, the HARQ information includes the bit map of HARQ process numbers, the bit map includes multiple bits, the value of the corresponding bit of HARQ process numbers of each transmission block is used for ACK the or NACK control character information for representing each transmission block, and the value of the corresponding bit of the corresponding HARQ process numbers of subframe without transport block transmission is used to represent ACK control character information.

For example, with reference to figure l id, the UE does not send HARQ process numbers, only send a bit map, 13 bits are included in the bit map, each bit represents 1-12 totally 13 HARQ process numbers successively, for example, HARQ process numbers are 0, 1, 2, a transmission block is received when 12 respectively, then there is the value of the corresponding bit of HARQ process numbers of transmission block to be used for ACK the or NACK control character information for representing each transmission block, other do not have the value of the corresponding bit of HARQ process numbers of transmission block to be used to represent ACK control character information, at this moment, what it is due to the representative of ACK control characters information is to have received and be successfully decoded data, without sending data again, therefore other do not have the value of the corresponding bit of HARQ process numbers of transmission block to be used to represent ACK control character information, re-transmission of the base station to data will not be caused；

5th kind of form, the HARQ information includes the bit map of HARQ process numbers, two bits represent a HARQ process number in the bit map, the value of corresponding two bits of HARQ process numbers of each transmission block is used for ACK the or NACK control character information for representing each transmission block, and the value of corresponding two bits of the corresponding HARQ process numbers of subframe without transport block transmission is used to represent DTX control character information.For example, with reference to figure l ie, the UE does not send HARQ process numbers, only send a bit map, 26 bits are included in the bit map, each two bit represents a HARQ process number, 26 bits represent 1-12 totally 13 HARQ process numbers successively, for example, HARQ process numbers are 0, 1, 2, a transmission block is received when 12 respectively, then there is the value of the corresponding bit of HARQ process numbers of transmission block to be used for ACK the or NACK control character information for representing each transmission block, other do not have the value of the corresponding bit of HARQ process numbers of transmission block to be used to represent DTX control character information, wherein, the DTX control characters information is used to represent that the process number does not receive data.

Specifically, for the transmission of HARQ feedback information, can be sent together with the other information in the unauthorized cell contextual information；Can also using punching by the way of piggyback HARQ feedback informations, i.e., by the other information in contextual information in addition to HARQ feedback information be put into authorize cell distribute to after the ascending resource of the UE, HARQ information is put by the way of punching Enter the ascending resource of the UE.So, for recipient, lost equivalent to data by some, but remain to decoding.

In addition, when unauthorized cell meets power headroom reporting (PHR) PHR trigger condition, trigger PHR, after the UE determines that the unauthorized cell is unavailable, if the unauthorized cell is still in state of activation, the state of activation refers to there is a packet data inactivity timer inside the UE, the timer has not timed out, or, the base station of the UE accesses does not issue the message that the cell has been deactivated to the UE, the PUSCH resources or PUCCH resource that then the UE is sent by the mandate cell of reception send PHR to mandate cell, the UE has following three kinds of forms when sending PHR information：The UE sends the PHR information of the cell of all activated state, meanwhile, increase a mark before the PHR of disabled unauthorized cell, it is described to identify for representing that the cell is unavailable；The UE sends the PHR information of all activated state cell；The UE sends the PHR information of all available activated state cells.

If the 1004, the UE sends the first data to the unauthorized cell, the corresponding contextual informations of the UE that the unauthorized cell is sent are not received in preset time period, the UE retransmits the first data by the mandate cell to the unauthorized cell；Specifically, the UE passes through the Physical Uplink Shared Channel resource PUSCH for the authorizing cell distribution or special physical uplink control channel resource PUCCH for distributing to the UE, by first data re-transmitting to the mandate cell, to cause the mandate cell to send first data to unauthorized cell.If the UE sends the first data to the unauthorized cell, now unauthorized cell spectrum resource is changed into unavailable from available, the UE does not receive the corresponding contextual informations of the UE that the unauthorized cell is sent in preset time period, now, the UE passes through the Physical Uplink Shared Channel resource PUSCH for the authorizing cell distribution or special physical uplink control channel resource PUCCH for distributing to the UE, by first data re-transmitting to the mandate cell, to cause the mandate cell to send first data to unauthorized cell.Wherein, the PUSCH resources and PUCCH resource, be the unauthorized cell spectrum resource it is unavailable after, it is described to authorize cell to receive the disabled message of unauthorized cell spectrum resource that the unauthorized cell is sent, be the channel resource that the UE is distributed by the mandate cell.Likewise, recognizing whether the data that UE is sent need to send to authorize cell to be easy to To unauthorized cell, first data for being retransmitted to the unauthorized cell can also be identified by the UE, described to identify for indicating that the data block is sent to unauthorized cell.Specifically, the mode that the UE is identified to first data, refers to the mode being identified in step 1002 to the corresponding data of first nack message, the embodiment of the present invention is repeated no more to this.

If the 1005, carrying the second nack message in the corresponding contextual information of the unauthorized cell that the UE is sent to the unauthorized cell, the UE receives the unauthorized cell by authorizing the corresponding data of second nack message that cell is retransmitted.

Specifically, the UE is by authorizing the MAC entity of cell to receive the corresponding data of second nack message that the unauthorized cell is retransmitted to the UE.

If carrying the second nack message in the corresponding contextual information of the unauthorized cell that the UE is sent to the unauthorized cell, now, unauthorized cell spectrum resource is changed into unavailable from available, and the UE is by authorizing the MAC entities of cell to receive the corresponding data of second nack message that the unauthorized cell is retransmitted to the UE.

Specifically, the unauthorized cell sends the corresponding data of the second nack message of repeating transmission to the mandate cell, the corresponding data of second nack message are sent to the UE by mandate cell MAC entities.Same, recognize whether the data that unauthorized cell is sent need to send to unauthorized cell to authorize cell to be easy to, the corresponding data of second nack message for being retransmitted to the UE can also be identified by the unauthorized cell, described to identify for indicating that the data block is sent to the UE.Specifically, the mode that the unauthorized cell is identified to the corresponding data of second nack message, refers to the mode being identified in step 1002 to the corresponding data of second nack message, the embodiment of the present invention is repeated no more to this.

If the 1006, the UE receives the data that the unauthorized cell is sent, the corresponding contextual information of the unauthorized cell is not sent to the unauthorized cell, the UE is sent the corresponding contextual information of the unauthorized cell to the unauthorized cell by the mandate cell in preset time period.Specifically, the UE passes through the Physical Uplink Shared Channel resource PUSCH for authorizing cell distribution or the special physical uplink control channel for distributing to the UE in preset time period Resource PUCCH, the corresponding contextual information of the unauthorized cell is sent to cell is authorized, to cause the mandate cell to send the corresponding contextual information of unauthorized cell described in the data to unauthorized cell.If the UE receives the data that the unauthorized cell is sent, the corresponding contextual information of the unauthorized cell is not sent to the unauthorized cell, now, unauthorized cell spectrum resource is changed into unavailable from available, then the U E pass through the Physical Uplink Shared Channel resource PUS CH for the authorizing cell distribution or special physical uplink control channel resource PUCCH for distributing to the UE in preset time period, the corresponding contextual information of the unauthorized cell is sent to mandate cell, to cause the mandate cell to send the corresponding contextual information of unauthorized cell described in the data to unauthorized cell.Further, to ensure that the corresponding contextual information of the unauthorized cell can preferentially be sent, the UE sets precedence information for the protocol Data Unit MAC PDU comprising the corresponding contextual information of the unauthorized cell, the priority of the corresponding contextual information of the unauthorized cell is higher than general data, less than common MAC control signalings, and according to the precedence information of the contextual information, by the corresponding contextual information of the unauthorized cell by authorizing cell to send to the unauthorized cell.

Specifically, the corresponding contextual information of the unauthorized specifically includes at least one in the following parameter：

Hybrid automatic repeat-request HARQ, power headroom reporting (PHR) PHR, Slow rush state report BSR, robustness head compression ROHC, wireless spread-spectrum technology RLC state reports, PDCP PDCP state reports.

Wherein, the form of the HARQ feedback information in the corresponding contextual information of the unauthorized cell refers to the form of HARQ feedback information in the correspondence contextual informations of UE described in step 1003.Wherein, when UE contextual informations corresponding to the unauthorized cell transmission unauthorized cell, if PUSCH or PUCCH resource that the UE distributes to the UE by the mandate cell send the corresponding contextual information of the unauthorized cell, there is the following two kinds situation：Situation 1, the UE by the preceding N PUSCH resources of the distribution for authorizing cell or distribute to the preceding M special PUCCH resources of the UE in the second preset time period, the corresponding contextual information of the unauthorized cell is sent to the mandate cell, to authorize cell to send the contextual information to the unauthorized cell, wherein N is more than or equal to Ι, and Μ is more than or equal to 1.

If the unauthorized cell spectrum resource does not recover available in the first preset time period, described UE authorizes the top n PUSCH resources of the base station transmission of cell by connecing in the second preset time period or is allocated to the preceding M special PUCCH resources of the UE, and the corresponding contextual information of the unauthorized cell is sent to the base station of the mandate cell.

For the corresponding contextual information of the unauthorized cell is sent to the mandate cell as early as possible, the UE can pass through the corresponding contextual information of first available PUSCH resources or PUCCH resource transmission unauthorized cell in the second preset time period, if first available the PUSCH resources or PUCCH resource are not enough to all send the contextual information, the partial data in the contextual information can be sent by first available PUSCH resources or PUCCH resource, other data can be sent by second in the second preset time period available PUSCH resources or PUCCH resource, until the contextual information is all sent completely.

If situation 2, the UE receive the J PUSCH resource for authorizing cell to send in same subframe, wherein, J>1, the UE judge the H PUSCH resource of transmission capacity in the J PUSCH resources not less than the contextual information size of the unauthorized cell, wherein, 1<The corresponding contextual information of the unauthorized cell is sent to the unauthorized cell and specifically included by UE described in=H by the mandate cell：The UE passes through the minimum PUSCH resources of call number in the H PUSCH resources, the corresponding contextual information of the unauthorized cell is sent to the mandate cell, to cause the mandate cell to send the corresponding contextual information of the unauthorized cell to the unauthorized cell.If the UE receives the PUSCH resources that multiple mandate cells are sent in the same subframe of the second preset time period, for example, if UE is it is determined that a sub- frame in after the unauthorized cell spectrum resource is unavailable, receive 4 PUSCH resources, numbering is PUSCHl, PUSCH2, PUSCH3 and PUSCH4, call number order from small to large according to the mandate cell for sending this four PUSCH resources arranges this four PUSCH resources and is followed successively by PUSCH2, PUSCH3, PUSCH4 and PUSCHl, which PUSCH resource the UE selects send the corresponding contextual information of the unauthorized cell, existing two schemes：The PUSCH resources that the minimum mandate cell of the UE Selecting Indexes number is sent send the corresponding contextual information of the unauthorized cell, for example, in PUSCH1-PUSCH4, the PUSCH resources that the minimum mandate cell of call number is sent are PUSCH2, then the UE sends the corresponding contextual information of the unauthorized cell by PUSCH2.If the amount of capacity for the PUSCH2 that the minimum mandate cell of the call number is sent once can not believe the corresponding context of the unauthorized cell Breath is once sent completely, then the UE abandons the PUSCH2, and selection authorizes cell index number to come the PUSCH resources that deputy mandate cell is sent according to from small arrival, is herein PUSCH3.If the corresponding context of the unauthorized cell can not be once sent completely by PUSCH3, the UE determines available PUSCH resources according to the method described above, finally.

If situation 3, the UE receive the J PUSCH resource for authorizing cell to send, wherein J in same subframe>1, the UE is sent the corresponding contextual information of the unauthorized cell to the mandate cell by the first K minimum PUSCH resource for authorizing cell to send of call number, to cause the mandate cell to send the corresponding contextual information of the unauthorized cell to the unauthorized cell, wherein, 1< =K < =J.

The PUSCH resources that the minimum mandate cell of the UE selections call number is sent send the corresponding contextual information of the unauthorized cell, if the corresponding contextual information of the unauthorized cell once can not be once sent completely by the PUSCH resources, then the UE sends a part of data by the PUSCH resources, remaining data arrange heel row according to order from small to large by call number and sent in the PUSCH resources that deputy mandate cell is distributed, in this way, until all data are sent completely.For distance, the UE first passes through the PUSCH resources of the minimum mandate cell distribution of call number, that is PUSCH2 sends the contextual information, if PUSCH2 off-capacity once to send the contextual information completely, then the UE sends a part of data by PUSCH2, remaining data are sent by PUSCH3, in this way, until whole contextual informations are sent.

If the 1007, the UE has been received by the second data that the unauthorized cell is sent, failed in preset time period to send the corresponding contextual information of the unauthorized cell to the unauthorized cell, the UE receives the second data that the unauthorized cell is retransmitted by the mandate cell.Specifically, the UE is by authorizing the MAC entity of cell to receive second data that the unauthorized cell is retransmitted.

If the UE has been received by the second data that the unauthorized cell is sent, now, unauthorized cell spectrum resource is changed into unavailable from available, and the UE fails in preset time and sends the corresponding contextual information of the unauthorized cell to the unauthorized cell, now, unauthorized cell can send the second data of the repeating transmission to cell is authorized, and be sent second data to the UE by MAC entities by mandate cell.Likewise, in order to authorize cell to be easy to recognize whether the data that unauthorized cell is sent need to send to unauthorized cell, the unauthorized cell can also will be retransmitted to described the of the UE Two data are identified, described to identify for indicating that the data block is sent to the UE.Specifically, the mode that the unauthorized cell is identified to second data, refers to the mode being identified in step 1002 to second data, the embodiment of the present invention is repeated no more to this.

The technical scheme described based on above-described embodiment, the present invention can cause when the frequency spectrum resource of unauthorized cell is unavailable, UE and unauthorized cell can be by authorizing cell to be in communication with each other, and then reduce unauthorized cell spectrum resource it is unavailable when influence to data transfer, lift message transmission rate, the availability of frequency spectrum is improved, the waste of resource is reduced.In UE contextual informations corresponding to the unauthorized cell transmission unauthorized cell, in order to prevent frequency spectrum resource that UE or unauthorized cell frequent switching are used, the embodiment of the present invention additionally provides a kind of method of data transfer, with reference to Figure 12, this method is the specific descriptions to above method embodiment, including：

1201st, user equipment (UE) determines that the frequency spectrum resource of unauthorized cell is unavailable.

Wherein, the detailed process of step 1201 can be found in the step 1001 in above-described embodiment, and the embodiment of the present invention is repeated no more to this.

1202nd, in the first preset time period, the UE determines whether the frequency spectrum resource of the unauthorized cell recovers available.

After the UE determines that the unauthorized cell spectrum resource is unavailable, if the unauthorized cell spectrum resource recovers available in the first preset time period, the unauthorized cell spectrum resource then can be continued through between the UE and the unauthorized cell to be communicated, such as described U E send the corresponding contextual information of unauthorized cell to the unauthorized cell or the UE receives the corresponding contextual informations of the UE that the unauthorized cell is sent.In first preset time period, the unlicensed spectrum resource does not recover available, if the UE is in the following two kinds state with the unauthorized cell：The UE sends data to the unauthorized cell, does not receive the corresponding contextual informations of the UE that the unauthorized cell is sent also；Or the UE receives the data that the unauthorized cell is sent, also the corresponding contextual information of the unauthorized cell is not sent to the unauthorized cell； Now, the UE can not communicate with the unauthorized cell, the corresponding contextual informations of the UE or the UE that i.e. described UE can not receive the unauthorized cell transmission can not send the corresponding contextual information of the unauthorized cell to the unauthorized cell, the UE will not authorize cell retransmission data to described, the unauthorized cell will not result in the waste of resource to the UE retransmission datas yet.And if now the UE is communicated with the unauthorized cell under above-mentioned two states, the channel resource that other UE are in communication with each other with the mandate cell may be taken, cause other data to postpone transmission time.Therefore, when unauthorized cell spectrum resource is unavailable, if the UE is in above two state with the unauthorized cell, the UE is it needs to be determined that whether the frequency spectrum resource of the unauthorized cell recovers available in the first preset time period, if in the first preset time period, the unauthorized cell spectrum resource recovery can use, then the UE is communicated with the unauthorized cell by the frequency spectrum resource of unauthorized cell, so, can be in the case where not influenceing the UE and the unauthorized cell data transmission, it is further to save resource.

If the 1203, not recovering available, if the UE sends data to the unauthorized cell, the UE receives the corresponding contextual informations of the U E that the unauthorized cell is sent by the mandate cell in the second preset time period；If the UE receives the data that the unauthorized cell is sent, the UE is sent the corresponding contextual information of the unauthorized cell to the unauthorized cell by the mandate cell in the second preset time period.

After more than first preset time period, into the second preset time period, if the frequency spectrum resource of the unauthorized cell does not recover available, it can not still be communicated between the UE and the unauthorized cell, in the following two kinds state,：

The UE sends data to the unauthorized cell, does not receive the corresponding contextual informations of the UE that the unauthorized cell is sent also；Or the UE receives the data that the unauthorized cell is sent, also the corresponding contextual information of the unauthorized cell is not sent to the unauthorized cell.

Now, if can not still be communicated between the UE and the unauthorized cell, the re-transmission of data is likely to result in, the waste of resource is caused.

For example, if the UE sends data to the unauthorized cell, the corresponding contextual informations of the UE that the unauthorized cell is sent are not received also, now, the unauthorized is small Area's frequency spectrum resource is changed into unavailable from available, in the first preset time period, if the unauthorized cell spectrum resource does not recover available, data transfer between the UE and the unauthorized cell is unaffected, but, if in second time period, the UE can't receive the corresponding contextual informations of the UE that the unauthorized cell is sent, even if the unauthorized cell has been received by the data of the UE transmissions and is successfully decoded, the UE still can retransmit the data to the unauthorized cell, or the UE does not retransmit data in MAC layer, but retransmit data in higher, cause the waste of resource.Therefore, in the second preset time period, the UE and the unauthorized cell are in default second time period by authorizing cell to be communicated.Again for example, if the UE receives the data that the unauthorized cell is sent, also the corresponding contextual information of the unauthorized cell is not sent to the unauthorized cell, now, the unauthorized cell spectrum resource is changed into unavailable from available, in the first preset time period, if the unauthorized cell spectrum resource does not recover available, data transfer between the UE and the unauthorized cell is unaffected, but, if in second time period, the UE can't send the corresponding contextual information of the unauthorized cell to the unauthorized cell, even if the UE has been received by the data of the unauthorized cell transmission and is successfully decoded, the unauthorized cell still can retransmit the data to the UE, or the UE is not in MAC layer retransmission data, but in higher retransmission data, cause the waste of resource.Therefore, in the second preset time period, and the unauthorized cell in default second time period by authorizing cell to be communicated.

Wherein, first preset time period and second preset time period and be the UE or unauthorized cell after transmitting data, wait the time of contextual information.Wherein, first preset time period can be preset with the second preset time period according to actual conditions, and the embodiment of the present invention is not limited this.Specifically, a timer and a time window can be preset in UE, the duration of the timer and time window has corresponded to first preset time period and the second preset time period respectively, after the UE determines that the unauthorized cell spectrum resource is unavailable, opening timing device, detect whether the unauthorized cell spectrum resource can use after timer startup, if the unauthorized cell spectrum resource recovers available in timer length, the UE can be communicated with the unauthorized cell by the frequency spectrum resource of the unauthorized cell；If the unauthorized cell spectrum resource does not recover available in timer duration, the UE opens a time window, time window unlatching after the UE with the unauthorized cell by authorizing cell to be communicated, i.e. described UE receives the PUSCH resources or PUCCH resource for authorizing cell to distribute, and passes through the PUSCH resources or PUCCH Resource sends the corresponding contextual information hair of the unauthorized cell to the unauthorized cell by the mandate cell, or receives the corresponding contextual informations of the UE that the unauthorized cell is sent by the mandate cell.Certainly, it is the known technology of those skilled in the art for the setting of timer and time window; and; any one skilled in the art the invention discloses technical scope in, change or replacement can be readily occurred in, should be all included within the scope of the present invention.Based on this method, the present invention can cause when the frequency spectrum resource of unauthorized cell is unavailable, UE and unauthorized cell can be by authorizing cell to be in communication with each other, and then reduce unauthorized cell spectrum resource it is unavailable when influence to data transfer, lift message transmission rate, the availability of frequency spectrum is improved, the waste of resource is reduced.

The embodiments of the invention provide a kind of method of data transfer, the executive agent of this method is unauthorized cell base station, and the base station provides service to unauthorized cell, and with reference to Figure 13, this method includes：1301st, first base station determines that the frequency spectrum resource of unauthorized cell is unavailable, and the unauthorized cell provides service by the first base station.

Specifically, the first base station rob account for a unlicensed spectrum resource when, the time that the unlicensed spectrum resource is used by the first base station can be calculated, therefore, the first base station can use the time of the unlicensed spectrum resource according to the first base station, determine whether the unauthorized cell spectrum resource can use.

1302nd, the first base station is communicated via cell and the unauthorized cell is authorized with user equipment (UE), and the mandate cell provides service by the second base station or the first base station.

Specifically, if the first base station receives the corresponding contextual information of the unauthorized cell that the UE is sent, the 2nd NACK information is carried in the corresponding contextual information of the unauthorized cell, the first base station passes through second base station and retransmits the corresponding data of second nack message to the UE;

If the first base station sends data to the UE, the first base station receives the corresponding contextual information of the unauthorized cell that the UE is sent by second base station in preset time period；
