Physical Downlink Control CHannel) on perhaps dynamic configuration or matched by semi-static in random access response
It sets, it can be in the Modulation and Coding Scheme of which carrier wave transmitting data and use of which comprising terminal in uplink authorization instruction time
Deng.After terminal obtains the uplink authorization instruction of base station distribution, upstream data can be sent in specified time-frequency domain resources.
In order to carry out the transmission of upstream data, in the side UE, medium access control (MAC, Media Access Control)
Layer need to obtain from physical layer relevant hybrid automatic repeat-request (Hybrid Automatic Repeat reQuest,
HARQ) information.There are a HARQ entity, the parallel HARQ processes of HARQ entity maintaining certain amount for the side UE, to realize
It waits and continues continuously to transmit during feedback whether last transmission success.In a given Transmission Time Interval
(TTI, Transmission Time Interval), if indicating the uplink authorization instruction of the TTI, HARQ entity is that will send out
Raw transmission determines a HARQ process.HARQ entity is also the HARQ feedback correct/error response received from physical layer
(ACK/NACK, Acknowledgement/Negative Acknowledgement) information, modulation and coding strategy (MCS,
Modulation and Coding Scheme) information and resource information be sent to corresponding HARQ process.Each HARQ process
Correspond to a harq buffer area (buffer).Currently, using synchronous sending method is generally used when retransmitting data packet, i.e.,
When retransmitting data packet, terminal can retransmit the number in the place of the fixation relative to the HARQ process for transmitting the data packet for the first time

Specific embodiment
First introduce the process that uplink synchronous in the related technology sends data below: terminal receives what base station was sent
PDCCH, if indicated in PDCCH comprising uplink authorization, the terminal determines HARQ according to the subframe for receiving uplink authorization instruction
Process number, and obtain HARQ state of a process information, then terminal is believed according to uplink authorization instruction and HARQ state of a process
Breath carries out determining whether to trigger primary re-transmission (transmission again for the data packet being transmitted across before) or triggering is primary
New biography (first time for the data packet not sent before transmits): where HARQ state of a process information includes at least:
Before HARQ process once transmission in NDI value, the buffer state of HARQ process, wherein buffer state include buffer area whether
For it is empty and whether NULL.Specifically,
If uplink authorization indicates not with Cell Radio Network Temporary Identifier/Identity, Cell-RNTI (T-CRNTI, Temporary Cell
Radio Network Temporary Identifier) mark PDCCH in, and if new number in correlation HARQ information
It is turned over according to instruction (NDI, New Data Indicator) compared to the value in once being transmitted before the HARQ process, alternatively, if
Uplink authorization is indicated in radio network temporary identifier (C-RNTI, Cell Radio the Network Temporary with cell
Identity) in the PDCCH identified, and the buffer area of the HARQ process is empty (data i.e. in buffer area are empty), alternatively,
If the uplink authorization instruction in random access response, notifies the primary new transmission of corresponding HARQ process triggers；It is no
Then, adaptive retransmission of corresponding HARQ process triggers is notified.
If the PDCCH that terminal receives base station transmission does not include uplink authorization instruction, the corresponding HARQ process of the TTI
Buffer area non-empty (data in buffer area be not empty), notify the once non-adaptive re-transmission of corresponding HARQ process triggers；Phase
In the technology of pass, the processing for the buffer area (buffer) of corresponding HARQ process be it is such, when new biography, by data or
Data packet is saved in buffer area；Confirmation (ACK) information is only received, buffer area is not dealt with；When number of retransmissions is more than maximum
Number, then clear buffer.
In the related technology, terminal is when data need to retransmit, if the resource competed using finishing, or
It can only arrive, could execute until resource contention then data retransmission processes cannot be executed normally to resource without competition again
Data retransmission processes (so abnormal situation would tend to occur in the related technology, need to wait long time that could send
Success)；If number of retransmissions exceeds maximum times, the time delay that data can be made to send is elongated, eventually leads to packet loss.Related skill
Another major reason of packet loss is in art, due to not having competition, according to the prior art, can only ceaselessly wait, when always to resource
When not competing resource, just abandon.
In order to solve the problems, such as that the synchronization sending method of the upstream data under unauthorized carrier wave scene, the present invention are real
The asynchronous sending mode or method of upstream data will be introduced, that is, carry by PDCCH under unauthorized carrier wave scene by applying example
HARQ process number is scheduled, and re-transmission is dispatched always by PDCCH.
Each embodiment in order to better understand the present invention, first introduces several concepts:
It retransmits, refers to the transmission again to the data packet being transmitted across before；
New biography refers to the first time transmission for the data packet not sent before one；
The synchronization sending method of the upstream data under unauthorized carrier wave scene, i.e. terminal receive uplink authorization in the related technology
The subframe of instruction and send upstream data and between time interval and terminal send upstream data and receive between corresponding
Time interval is fixed.It is shown in Figure 1, in the related art, if terminal receives the upper of base station at the time of subframe 0
Row authorization instruction, then terminal is in the subframe (subframe that sub-frame interval is 4 from receiving the subframe moment that uplink authorization indicates always
Number to send upstream data on 4)；Terminal is by the subframe that sub-frame interval is 4 from the subframe for sending upstream data, (subframe numbers are
8) response message (such as nack message) is received, it, be into if terminal receives the nack message of base station at the time of subframe numbers are 8
Row retransmits, and terminal be always from the subframe for receiving nack message fixed sub-frame interval be 4 subframe (subframe numbers are
12) it is retransmitted on.
Lower mask body introduces a kind of asynchronous transmission method using upstream data of proposition of the embodiment of the present invention, the party
The realization process of method is such that
Terminal receives the PDCCH that base station is sent, and indicates comprising uplink authorization, carries HARQ in the uplink authorization instruction
The identification information of process, the terminal determine HARQ state of a process information according to the identification information of HARQ process, then terminal is extremely
It is few to be carried out determining whether to trigger primary re-transmission or triggering according to uplink authorization instruction and HARQ state of a process information
New biography, specifically, referring to table 1, if the NDI in correlation HARQ information is compared to the value in once transmitting before the HARQ process
It is turned over, alternatively, if uplink authorization instruction is in the PDCCH identified with C-RNTI and the buffer area of the HARQ process is sky
(data in buffer area are sky), alternatively, if this HARQ process or transmission block (TB, Transport Block) first
The uplink scheduling received, that is, before without the data of any NDI, alternatively, if uplink authorization instruction is in random access response
In, then notify new biography of corresponding HARQ process triggers；Otherwise, corresponding HARQ process triggers is notified once to retransmit.
Table 1
In embodiments of the present invention, re-transmission and new biography can use identical HARQ process or different HARQ processes, need
It is noted that terminal can be in the HARQ process for transmitting the data packet for the first time when using identical HARQ process
Variable time interval (identical subframe) retransmits the data packet；Referring to fig. 2, if terminal receives base station at the time of subframe 0
Uplink authorization instruction, if terminal is judged as carry out new biography, terminal can be 5 in subframe numbers (can be the new biography moment with
The subframe for receiving uplink authorization instruction is not fixed intervals, and indicates this interval in uplink authorization instruction) carry out new biography；Such as
Fruit terminal receives the uplink authorization instruction of base station at the time of subframe numbers are 8, is retransmitted if terminal is judged as, terminal exists
Subframe numbers are that 14 (can be retransmission time with the subframe for receiving uplink authorization instruction is not fixed intervals, or in uplink authorization
This interval is indicated in instruction) on retransmitted.As it can be seen that in embodiments of the present invention, the sub-frame interval of new biography and re-transmission is not
The same.
Here, RV is used for the different editions for showing to send data, to merge when receiving data according to version.This
The time interval sent in inventive embodiments is not fixed, i.e., the embodiment of the present invention sends upstream data using variable time interval
There is important influence to technical problem is solved, specifically, interval in the related technology is fixed, if regular time does not provide
Source can be used to retransmit or new biography, just can only wait next fixed intervals just and can be carried out transmission；And it is spaced in the embodiment of the present invention
It is not fixed, then can be sent when having resource.Certainly, in another embodiment of the invention, retransmit and new biography
It can be using fixed intervals in the related technology.Whether ACK information and ACK to retransmitting and play an important role in the related technology, and
In the embodiment of the present invention, will not there are ACK information and NACK again, whether terminal, which retransmits, is determined according to information shown in table 1.
In the embodiment of the present invention, the processing for corresponding buffer area be it is such, each HARQ process is corresponding with one
Buffer area (buffer)；
Method one: when new biography, storing data into buffer area, has next time new biography again by data cover, phase
It is removed when in original buffer area, new data save.
Method two: it when receiving retransfer scheduling, retransmits and new biography is not the same HARQ process, the data for needing to retransmit are turned
It moves on in the buffer area of the HARQ process retransmitted.
Both the above method, when the resource use competed finishes, data are not yet sent successfully completely, will be all relevant
It removes buffer area.Resource contention process is carried out for base station, it is that base station needs that terminal resource is notified to compete as a result, being arrived comprising competition
Resource time-frequency domain information.Alternatively, buffer area retains, it is arranged timer (being arranged as unit of unauthorized carrier wave), more than one
It fixes time and does not receive new uplink authorization instruction, remove all buffer areas.
The technical solution of the present invention is further elaborated in the following with reference to the drawings and specific embodiments.
