Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
The two ends of data interaction include but are not limited to base station and subscriber equipment (User Equipment in the embodiment of the invention, UE), owing to carry out the interactive data transmission between base station and the UE, so both being transmitting terminal separately, base station and UE also be receiving terminal, explain with transmitting terminal and receiving terminal in the following embodiments, transmitting terminal in the practical application and receiving terminal can have the equipment of data-transformation facility for base station or UE or other.
The embodiment of the invention provides a kind of method of transfer of data, and as shown in Figure 1, described method comprises the steps:
101, transmitting terminal just passes packet or data packet group to receiving terminal.
With the packet is example, and transmitting terminal transmission primaries packet can take a TTI.
For the data packet bundling technology, transmitting terminal can also be to receiving terminal transmits data packets group, and described data packet group can take a plurality of TTI, for example, each data packet group can take four TTI continuously and transmit, and comprises four identical packets in every group of data packet group.
102, when do not receive that receiving terminal sends to the ACK information of packet or described data packet group the time, transmitting terminal retransmits at least once this packet or data packet group to receiving terminal.
With the packet is example, and transmitting terminal can continue to retransmit this packet to receiving terminal after receiving terminal just passes packet.Number of retransmissions is at least once, and the embodiment of the invention is not done qualification to the number of retransmissions upper limit.
The method of the transfer of data that the embodiment of the invention provides, can be after just passing packet or data packet group to receiving terminal, at least once retransmit this packet or data packet group to receiving terminal, can solve in the prior art, the problem that each re-transmission all must just can be carried out after receiving feedback information, thereby can save the time of waiting for feedback information, reduce the propagation delay time of data.
Further, the embodiment of the invention also provides a kind of method of transfer of data, and as shown in Figure 2, described method is that described method can comprise to the further expanding of the described method of Fig. 1:
201, transmitting terminal just passes packet or data packet group to receiving terminal.
With the packet is example, and transmitting terminal transmission primaries packet can take a TTI.
For the data packet bundling technology, transmitting terminal can also be to receiving terminal transmits data packets group, and described data packet group can take a plurality of TTI, for example, each data packet group can take four TTI continuously and transmit, and comprises four identical packets in every group of data packet group.
202, transmitting terminal retransmits at least once this packet or data packet group to receiving terminal.
With the packet is example, and transmitting terminal can continue to retransmit this packet to receiving terminal after receiving terminal just passes packet.Number of retransmissions is at least once, and the embodiment of the invention is not done qualification to the number of retransmissions upper limit.
Further, transmitting terminal serves as the standard that whether retransmits with the ACK information that whether receives receiving terminal and send.When transmitting terminal received described ACK information, from receiving the TTI of described ACK information, transmitting terminal was after this no longer to the receiving terminal retransmission data packet may; If transmitting terminal does not receive described ACK information, then transmitting terminal continues repeatedly to retransmit described packet to receiving terminal.Described ACK information is the correct confirmation that receiving terminal sends to transmitting terminal, and this information representation receiving terminal correctly receives the packet that transmitting terminal sends.
Before correctly receiving packet, receiving terminal can repeatedly can't correctly receive described packet, and when taking defeat each time, receiving terminal all can send a nack message to transmitting terminal, and described nack message is used to represent that receiving terminal takes defeat.Need to prove that herein whether transmitting terminal retransmits and when retransmit packet and do not rely on described nack message in embodiments of the present invention.
Further, can obtain indication information at interval at execution of step 201 back transmitting terminals, when UE was transmitting terminal, described interval indication information can send to UE by the base station.The TTI that need wait for when described interval indication information is used to indicate each retransmission data packet may or data packet group is number at interval.
With the packet is example, and when channel resource enough transmitted some packets, transmitting terminal just had enough channel resources to retransmit this packet continuously to receiving terminal after just passing packet to receiving terminal, and at this moment, the TTI number in the indication information of described interval is zero.Many transmit end receive end is used simultaneously but often transmit a plurality of packets in the practical application or have, in this case, the first biography of certain packet and retransmit between, just need one or more TTI at interval between retransmitting and retransmitting.And how to be a plurality of allocation of packets channel resources, how the transmission intercal between promptly per two packets to determine, can be according to the actual needs setting, and present embodiment is not done qualification to this.
The TTI that need wait for when described interval indication information is each retransmission data packet may is number at interval, need to prove:
1) wait of each retransmission data packet may at interval can be different.Need to carry out to retransmit for three times just can be received to rectify after just passing with a certain packet and really be received as example: just pass with retransmit for the first time between, for the first time retransmit with retransmit for the second time between and re-transmission for the second time and for the third time the interval between the re-transmission both can all be a TTI, also can be respectively one, two, three TTI, can also be respectively one, one, two TTI.The embodiment of the invention whether the interval between per twice transmission of same packet is equated and per twice transmission between at interval TTI number do not limit.
2) described interval indication information can be aimed at the interval indication information of transmitting terminal, and transmitting terminal is all waited for according to the interval T TI that this interval indication information is indicated all packets of this transmitting terminal transmission according to this interval indication information.Described interval indication information also can be aimed at the interval indication information of packet, and transmitting terminal is waited for the different interval TTI of different pieces of information bag according to the indication of interval indication information according to the interval indication information that is directed to the different pieces of information bag.
Transmitting terminal repeatedly retransmits this packet according to the interval indication information to receiving terminal.TTI interval between re-transmission and the first biography and the TTI interval between re-transmission and the re-transmission can be stipulated that this interval indication information (after promptly first biography packet) before the transmitting terminal retransmission data packet may first time obtains by an interval indication information.TTI interval between re-transmission and the first biography and the TTI interval between re-transmission and the re-transmission also can be stipulated by many interval indication informations, every the interval indication information need between per twice transmission to stipulate TTI number at interval, and this interval indication information obtains before in each transmission (just passing or re-transmission).
Do not do the upper limit for the number of times of transmitting terminal retransmission data packet may in the embodiment of the invention and limit, the higher limit of number of retransmissions can be according to the needs of practical application by being configured.
Preferably, transmitting terminal can be judged the TTI interval that each retransmission data packet may or data packet group need be waited for voluntarily, does not promptly need to obtain indication information at interval.Concrete, when channel resource enough transmitted some packets, transmitting terminal retransmitted continuously to packet; When channel resource was not enough to transmit some packets, transmitting terminal was judged the TTI interval that each retransmission data packet may need be waited for, and after waiting for according to judgement, retransmission data packet may.
Transmitting terminal serves as the standard that whether retransmits with the ACK information that whether receives receiving terminal and send.When transmitting terminal received described ACK information, from receiving the TTI of described ACK information, transmitting terminal was after this no longer to the receiving terminal retransmission data packet may; If transmitting terminal does not receive described ACK information, then transmitting terminal continues repeatedly to retransmit described packet to receiving terminal according to the interval indication information.Described ACK information is the correct confirmation that receiving terminal sends to transmitting terminal, and this information representation receiving terminal correctly receives the packet that transmitting terminal sends.
Present embodiment can be applied to following application scenarios, and this application scenarios is not as the qualification to the embodiment of the invention.As shown in Figure 3, with transmitting terminal a certain packet being retransmitted continuously is example: with respect to this packet, when channel resource relatively sufficient, in the time of needn't waiting for all between for example per twice transmission that TTI at interval, first biography and re-transmission to this packet take TTI0 in proper order, TTI1, TTI2...... transmit, that is to say does not have TTI at interval between each transmission, suppose that receiving terminal correctly receives this packet when transmitting terminal retransmits for the third time, when promptly on TTI3, correctly receiving this packet, receiving terminal can send ACK information to transmitting terminal (four TTI of transmitting terminal after each transmission receives feedback information) on the TTI7, propagation delay time is three TTI in such cases, if a TTI is 10 milliseconds, then propagation delay time is 30 milliseconds.Transmitting terminal no longer retransmits this packet after receiving ACK information on the TTI7.
In the prior art, owing to need all to wait for that the feedback information of receiving terminal is (before receiving terminal correctly receives this packet before each the re-transmission, described feedback information is a nack message), retransmit on the 4th TTI after receiving feedback information, needing between each transmission to cause seven TTI at interval thus.As shown in Figure 4, still correctly receiving this packet with receiving terminal when transmitting terminal retransmits for the third time is example, transmitting terminal takies TTI0, TTI8, TTI16 and TTI24 respectively to the first biography of this packet, re-transmission for the first time, re-transmission for the second time and re-transmission for the third time and transmits, if a TTI is 10 milliseconds, then propagation delay time in such cases is 240 milliseconds.The embodiment of the invention has reduced 210 milliseconds time delay with respect to prior art.
For the data packet group in the transmits data packets binding technology, as shown in Figure 5, with transmitting terminal a certain data packet group being retransmitted continuously is example: with respect to this data packet group, when channel resource is best, (needn't wait for all between per twice transmission that TTI at interval), first biography and re-transmission to this data packet group take TTI0-TTI3 in proper order, TTI4-TTI7, TTI8-TTI11...... transmit, there is not TTI at interval between each transmission, suppose that receiving terminal correctly receives this data packet group when transmitting terminal retransmits for the third time, when promptly on TTI12-TTI15, correctly receiving this data packet group, receiving terminal can send ACK information to transmitting terminal (four TTI of transmitting terminal after each transmission receives feedback information) on the TTI19, propagation delay time is 12 TTI in such cases, if a TTI is 10 milliseconds, then propagation delay time is 120 milliseconds.Transmitting terminal no longer retransmits this data packet group after receiving ACK information on the TTI19.
In the prior art, owing to need all to wait for that the feedback information of receiving terminal is (before receiving terminal correctly receives this data packet group before each the re-transmission, described feedback information is a nack message), receive feedback information on the 4th TTI of transmitting terminal after each transmission, and retransmit on the 9th to the 12 TTI after receiving feedback information, needing between each transmission to cause 12 TTI at interval thus.As shown in Figure 6, still correctly receiving this data packet group with receiving terminal when transmitting terminal retransmits for the third time is example, transmitting terminal takies TTI0-TTI3, TTI16-TTI19, TTI32-TTI35 and TTI48-TTI51 respectively to the first biography of this data packet group, re-transmission for the first time, re-transmission for the second time and re-transmission for the third time and transmits, if a TTI is 10 milliseconds, then propagation delay time in such cases is 480 milliseconds.The embodiment of the invention has reduced 360 milliseconds time delay with respect to prior art.
Optionally, prescribe a time limit when channel resource has, the embodiment of the invention still can reduce propagation delay time with respect to prior art.Concrete, suppose that four transmission (once just passing three times retransmits) all need three TTI at interval between any two, the time delay that receiving terminal correctly receives this packet is 12 TTI, promptly 120 milliseconds, still prior art has reduced 120 milliseconds time delay relatively.In addition, above-mentioned prior art is with synchronous hybrid automatic repeat request (Hybrid Automatic Repeat Request, HARQ) transmission means, promptly seven TTI in interval are that example describes between twice transmission, when the mode that adopts asynchronous HARQ is transmitted, at least at interval seven TTI between twice transmission, the propagation delay time of packet is bigger.
Need to prove that the time delay of data packet transmission is the time interval of this packet between being issued to that receiving terminal is correct and receiving from transmitting terminal, receive time interval between the ACK information but not this packet is issued to transmitting terminal from transmitting terminal.Because the time that receiving terminal correctly receives this packet receives the time of ACK information early than transmitting terminal, therefore transmitting terminal still retransmits this packet (fourth, fifth, six, seven re-transmission) after receiving terminal correctly receives this packet, till transmitting terminal receives ACK information.So the number of retransmissions (seven times) that can occur packet in Fig. 3 can correctly receive the number of retransmissions (three times) of this packet greater than receiving terminal, and the continuous situations that send ACK information for four times to transmitting terminal of receiving terminal.
Optionally, the packet or the data packet group that can be optionally priority be higher than pre-set level adopt above-mentioned steps 201 and the described implementation of step 202 to transmit, and the packet or the data packet group that priority are less than or equal to pre-set level adopt prior art to transmit.Under the limited condition of channel resource, optionally priority is higher than the packet of pre-set level or data packet group adopts above-mentioned steps 201 and the described implementation of step 202 to transmit, can improve priority and be higher than the packet of pre-set level or the transmission success rate of data packet group, guarantee quality of services for users.Described priority can be to determine according to the delay sensitive degree of packet or data packet group, for example, according to the delay sensitive degree of packet or data packet group the priority of packet or data packet group is set to one-level, secondary, three grades etc. from high to low.For VoP in the circuit domain business or data packet group, because the delay sensitive degree is higher, if crossing conference, propagation delay time influences user's communication experience, particularly when the conversation a certain Founder when carrying out transregional switching, the accumulation of handover delay and propagation delay time can reduce user's speech quality at double, and VoP or data packet group in can circuit domain business be set to one-level packet or data packet group.Perhaps, for the transmission of Online Video packet or data packet group, it is not smooth that excessive propagation delay time can cause user terminal video to play, and reduces user's experience, can the Online Video packet or data packet group be set to secondary data packet or data packet group.Can preferentially be higher than three grades to priority so, promptly priority is that the packet of firsts and seconds or data packet group adopt above-mentioned steps 201 and the described implementation of step 202 to transmit.In addition, can also be set to one-level, secondary, three grades etc. from high to low to the priority of packet or data packet group according to the size of packet or data packet group, big more packet or data packet group priority are high more.In data transmission procedure, with respect to little packet or data packet group, bigger packet or data packet group data carried by data content are more important, preferentially adopt above-mentioned steps 201 and the described implementation of step 202 to transmit, can reduce the influence of data transmission fails the customer service quality to bigger packet or data packet group.The priority of described packet or data packet group, and described pre-set level can adjust according to actual conditions, the embodiment of the invention does not limit this.
Optionally, can also determine that transfer resource on each TTI is whether less than default transfer resource threshold value, when the transfer resource on certain TTI during less than default transfer resource threshold value, packet or data packet group that this TTI is used for priority is higher than pre-set level at least once retransmit.As shown in Figure 7, in an application scenarios of the embodiment of the invention, be example with the packet, need to send three packets that priority is respectively one-level, secondary and three grades, wherein one-level is that limit priority and three priority of data packets all are higher than pre-set level.Suppose that each packet all needs to carry out to retransmit for three times the ability transmission success, taking TTI0 to TTI2 order respectively to the one-level packet, after three grades of packets of secondary data packet respectively carry out once just passing, determine that transfer resource on the TTI3 is whether less than default transfer resource threshold value, when the transfer resource on the TTI3 during less than default transfer resource threshold value, on TTI3, the one-level packet is once retransmitted, whether the transfer resource on definite then TTI4 is less than default transfer resource threshold value, when the transfer resource on the TTI3 during less than default transfer resource threshold value, on TTI3, secondary data packet is once retransmitted, by that analogy, final process is at TTI3, TTI6, retransmit for three times on the TTI9, the success of one-level data packet transmission, process is at TTI4, TTI7, retransmit for three times on the TTI10, the secondary data packet transmission success, process is at TTI5, TTI8, retransmit three grades of packet transmission success three times on the TTI11.Further, can also will transmit the next stage packet again after a certain level packet transmission success.As shown in Figure 8, suppose that still each packet all needs to carry out to retransmit for three times the ability transmission success, taking TTI0 to TTI2 order respectively to the one-level packet, after three grades of packets of secondary data packet respectively carry out once just passing, when the transfer resource on the TTI3 during less than default transfer resource threshold value, on TTI3, the one-level packet is carried out retransmitting the first time, when the transfer resource on the TTI4 during less than default transfer resource threshold value, on TTI4, the one-level packet is carried out retransmitting the second time, when the transfer resource on the TTI5 during less than default transfer resource threshold value, on TTI5, the one-level packet is retransmitted for the third time, according to the implementation of transmission one-level packet secondary and three grades of packets are transmitted then, promptly respectively at TTI6, TTI7, TTI8 is last to carry out three re-transmissions to secondary data packet, respectively at TTI9, TTI10, TTI11 is last to carry out three re-transmissions to three grades of packets.The application scenarios of the embodiment of the invention is that example describes with the transmits data packets, for the transmits data packets group, can be according to the characteristic of data packet group, and realize that according to the implementation of transmits data packets the embodiment of the invention is no longer given unnecessary details this.
Further, in the Another application scene of the embodiment of the invention, when determining when having enough channel resources, transmitting terminal can retransmit at least once described packet or data packet group to described receiving terminal on the TTI of assignment.Enough channel resources were for after passing (or a plurality of) packet or data packet group originally, and also residue can be transmitted the channel resource of a packet goods data packet group at least.Passed originally after a packet or the data packet group under the prerequisite that does not influence the base station load, as long as there is the residue channel resource, just utilize this residue channel resource that packet or data packet group are retransmitted, increase the number of retransmissions of packet or data packet group, further improve the success rate of packet or data packet group transmission.
Further again, in the Another application scene of the embodiment of the invention, can also be that described packet or data packet group are provided with number of retransmissions according to the priority of packet or data packet group, the packet that priority is high or the number of retransmissions of data packet group be greater than the low packet of priority or the number of retransmissions of data packet group.Concrete, can to packet or data packet group number of retransmissions be set according to the size or the delay sensitive degree of packet or data packet group, the packet that packet is big or the delay sensitive degree is high or the packet that number of retransmissions is little greater than packet or the delay sensitive degree is low or the data packet group of data packet group.When the number of retransmissions of a certain packet or data packet group surpasses default number of retransmissions, even receiving terminal does not correctly receive this packet or data packet group, also no longer this packet or data packet group are retransmitted, thereby guarantee to utilize other packets of limited transmission resources for transmitting or data packet group.
The method of the transfer of data that the embodiment of the invention provides, can be after just passing packet or data packet group to described receiving terminal, at least once retransmit this packet or data packet group to receiving terminal, can solve in the prior art problem that each re-transmission all must just can be carried out after receiving feedback information.Because transmitting terminal is waited for feedback information and according to described feedback information retransmission data packet may or data packet group certain time delay is arranged all, thereby the embodiment of the invention can be saved and be waited for feedback information and according to time of described feedback information retransmission data packet may or data packet group, can reduce the time delay of transfer of data.
In addition, the method of the transfer of data that the embodiment of the invention provides can also stop retransmission data packet may or data packet group when receiving the ACK information of receiving terminal transmission, other packets of the channel resource allocation that will save or data packet group can be optimized the configuration of channel resource.
In addition, the method of the transfer of data that the embodiment of the invention provides, can also be under the limited condition of channel resource, the technical scheme that preferentially adopts present embodiment to provide to some delay sensitive or big packet or data packet group, can carry out refinement to the characteristics of customer service, improve user's experience.
With reference to the realization of method embodiment shown in Figure 2, the embodiment of the invention provides a kind of device, as shown in Figure 9, and in order to realize method embodiment shown in Figure 2.Described device includes but are not limited to base station and UE, and described device comprises:
With the packet is example, and described transmitter 91 transmission primaries packets can take a Transmission Time Interval TTI.
For the data packet bundling technology, described transmitter 91 can also be to receiving terminal transmits data packets group, and described data packet group can take a plurality of TTI, for example, each data packet group can take four TTI continuously and transmit, and comprises four identical packets in every group of data packet group.
Described transmitter 91 also be used for when do not receive that receiving terminal sends to correct the affirmations ACK information of packet or described data packet group the time, to receiving terminal re-transmission at least once this packet or data packet group.Wherein, ACK information representation receiving terminal correctly receives this packet or data packet group.
Further, as shown in figure 10, described device can also comprise:
Acquiring unit 1001 is used to obtain indication information at interval, and described interval indication information is for retransmit the TTI number that described packet or data packet group need be waited at every turn.
The interval indication information that described transmitter 91 also is used for receiving according to described receiver 1001 is to receiving terminal retransmission data packet may or data packet group.
With the packet is example, and when channel resource enough transmitted some packets, described transmitter 91 just had enough channel resources to retransmit this packet continuously to receiving terminal after just passing packet to receiving terminal, and the TTI number in the indication information of promptly described interval is zero.Many base station and receiving terminal are used simultaneously but often transmit a plurality of packets in the practical application or have, in this case, the first biography of certain packet and retransmit between, just need one or more TTI at interval between retransmitting and retransmitting.The TTI that comes out is used for transmitting other packets at interval.And how to be a plurality of allocation of packets channel resources, how the transmission intercal between promptly per two packets to determine, can be according to the actual needs setting, and present embodiment is not done qualification to this.
The TTI that need wait for when described interval indication information is each retransmission data packet may is number at interval, need to prove:
1) wait of each retransmission data packet may at interval can be different.Need to carry out to retransmit for three times just can be received to rectify after just passing with a certain packet and really be received as example: just pass with retransmit for the first time between, for the first time retransmit with retransmit for the second time between and re-transmission for the second time and for the third time the interval between the re-transmission both can all be a TTI, also can be respectively one, two, three TTI, can also be respectively one, one, two TTI.The embodiment of the invention whether the interval between per twice transmission of same packet is equated and per twice transmission between at interval TTI number do not limit.
2) described interval indication information can be aimed at the interval indication information of transmitting terminal, and transmitting terminal is all waited for according to the interval T TI that this interval indication information is indicated all packets of this transmitting terminal transmission according to this interval indication information.Described interval indication information also can be aimed at the interval indication information of packet, and transmitting terminal is waited for the different interval TTI of different pieces of information bag according to the indication of interval indication information according to the interval indication information that is directed to the different pieces of information bag.
