Description
Technical field
The present invention relates to wireless communication technology field more particularly to a kind of re-transmission sides of enhancing mobile broadband service data
Method, device, base station and user equipment.
Background technology
EMBB (enhanced Mobile Broadband enhance mobile broadband) and URLLC (Ultra Reliability
And Low Latency Communication, the reliable low time delay communication of superelevation) it is 3GPP (3rd Generation
Partnership Project, third generation partner program) two kinds of 5G application scenarios defining.Wherein URLLC business clock synchronization
Prolong has very strict requirement with reliability.In order to meet this requirement, need to give URLLC traffic assignments big bandwidth so that
URLLC business completes highly-reliable transmission in stringent delay requirement.Since URLLC business has paroxysmal feature, if will
All bandwidth are only assigned to URLLC business, and the serious waste of frequency spectrum resource can be caused when no URLLC business reaches, is made
It is relatively low to obtain frequency spectrum resource utilization rate.In order to improve frequency spectrum resource utilization rate, URLLC business and eMBB business can be multiplexed this frequency
Spectrum resource.
Since eMBB business is different with the delay requirement of URLLC business, business feature is also different, the data of URLLC business
Typically small, in order to meet stringent delay requirement, URLLC business is scheduled using smaller time slot.EMBB business datums
It is generally large, it is scheduled according to identical time slot, signaling overheads can be significantly increased, to reduce frequency spectrum resource utilization rate,
Therefore eMBB business is scheduled using larger time slot.Since eMBB business is different from the scheduling granularity of URLLC business,
URLLC business may reach among some time slot of eMBB business, in order to ensure URLLC service reliabilitys and low time delay requirement
Under the premise of boost the efficiency of frequency resources utilization as far as possible, following scheme may be used：For downlink, URLLC business can
To seize the eMBB service resources transmitted.The program ensures the performance of URLLC business but eMBB business is caused
Serious negative impression increases eMBB business and successfully solves to reduce influence of the URLLC business to the eMBB business being preempted
The probability of code, may be used following scheme：For downlink, support seizes few time-frequency to eMBB business by URLLC business
The instruction of resource.
In the downlink, it is not seized by URLLC business in order to ensure the common signal of eMBB business, it can be when will be entire
Frequency resource is divided into two regions in a manner of frequency division multiplexing.As shown in Figure 1, entire running time-frequency resource is divided into two portions on frequency domain
Point, eMBB monopolizes frequency range and eMBB, URLLC are multiplexed frequency range.EMBB monopolizes frequency range and is only used for eMBB business, is transmitted in the frequency range
The common signal of eMBB business can ensure that the signal is not seized by URLLC business.EMBB, URLLC multiplexing frequency range are used for transmission
EMBB and URLLC business.It is multiplexed frequency range in eMBB, URLLC, when URLLC business is in some for the eMBB business transmitted
When being reached among gap, it is high to meet URLLC business ultralow time delay that URLLC business can seize the eMBB service resources transmitted
It is reliable to require, serious influence can be caused for the eMBB business transmitted in this way.Although base station notifies UE by instruction
Its eMBB business seizes portion of time frequency resources by URLLC business can improve the probability that UE is correctly decoded eMBB business, still,
When ratio that eMBB business is preempted is higher or MCS (Modulation Coding Scheme, the modulating-coding of eMBB business
Mode) it is higher when, in the case where there is instruction, the probability that eMBB business is correctly decoded is still very low.
In order to increase the probability that eMBB business is correctly decoded, the eMBB business datums seized by URLLC business can be existed
After the transmission time slot of the eMBB business, retransmitted on identical frequency spectrum resource.As shown in Fig. 2, URLLC business exists
The intermediate of eMBB time slots 1 reaches, and the time slot has been already allocated to eMBB business at this time, and URLLC business can seize the eMBB business
Frequency spectrum resource, after eMBB time slots 1, the eMBB business datums seized by URLLC business can be identical in eMBB time slots 2
It is retransmitted at once on frequency spectrum resource.Which can make eMBB business that probability is successfully decoded is unaffected and reduce as far as possible
The propagation delay time of eMBB business improves the handling capacity of UE.
Autonomous retransmission mode retransmits the eMBB seized by URLLC business in eMBB time slots 1 in the initial part of eMBB time slots 2
The data of business, when the initial part of eMBB time slots 2 is used to retransmit the eMBB business that eMBB time slots 1 are seized by URLLC business
When data, the available running time-frequency resource of original ready eMBB business datums in advance reduces on eMBB time slots 2, needs at this time
The code check of the data is improved to transmit within the shorter time, this way can increase the Block Error Rate of data, seriously affect system
Performance.In order to ensure that the Block Error Rate of transmission, another method are to reduce the TBS of original eMBB business datums on eMBB time slots 2
(Transport Block Size, transport block size) retransmits after then re-modulating coding.Due to URLLC business phases
Than the data packet of eMBB business is larger, and the time delay of the modulating-coding of eMBB business is greater than URLLC business, when URLLC business exists
It is reached at the end of eMBB time slots 1 are fast, URLLC business can seize 1 tail portion of eMBB time slots, and the eMBB seized by URLLC
Business datum can be retransmitted in the initial part of eMBB time slots 2.Change the TBS of original eMBB business datums on eMBB time slots 2 at this time
The time delay of modulating-coding is carried out afterwards reaches original eMBB business datums on transmission eMBB time slots 2 if more than from URLLC data
Time will prevent on eMBB time slots 2 original eMBB business datums from being sent.

Then the TBS and modulating-coding for data of being engaged in are sent in the latter half of eMBB time slots N+1.UE receives the data of eMBB time slots N
After seizing instruction, it may be determined that the running time-frequency resource that URLLC is seized is not belonging to the last M time slot of eMBB time slots N, therefore UE
Will eMBB time slots N+1 continue to the eMBB business datums seized by URLLC business, then complete decoding.With do not occur
It seizes and compares, propagation delay time at this time increases a URLLC slot length.
If (Te-(M+1)×TU-TUd) ＜ t≤(Te–M×TU-TUd), i.e. when reaching moment distance eMBB of URLLC business
Gap N terminates to be more than M × TU+TUdAnd it is not more than (M+1) × TU+TUd, t as shown in Figure 52Moment, at this time URLLC business can seize original
There is the frequency spectrum resource of eMBB time slots N to be located at the last M URLLC time slots of eMBB time slots N, M=1 in example as shown in Figure 5,
URLLC business is in t2When moment reaches, the frequency spectrum resource of the last one in eMBB time slots N (the 4th) URLLC time slots can be seized,
And the eMBB business datums for the original eMBB time slots N being preempted can be sent in the initial part of eMBB time slots N+2.At this point, base station
There is no time enough to go to change the TBS of the upper original eMBB business datums of eMBB time slots N+1 and modulating-coding and then in eMBB
The latter half of gap N+1 is sent.Therefore, it is necessary to the eMBB business datums of original eMBB time slots N are postponed an eMBB time slot.This
Shi Jizhan can change the TBS of original eMBB business datums on eMBB time slots N+2 again and modulating-coding is then in eMBB time slots N
+ 2 latter half is sent.
After UE receives the data of eMBB time slots N and seizes instruction, it may be determined that the running time-frequency resource that URLLC is seized belongs to
The last M time slot of eMBB time slots N, therefore UE has following three kinds of decoding processes.
Mode 1：UE completes decoding after the data for having received eMBB time slots N, according to instruction is seized, if successfully decoded, this
When propagation delay time with do not seize it is identical.If decoding failure, UE will eMBB time slots N+2 continue to by URLLC industry
The eMBB business datums that business is seized, then decode with together with eMBB time slots N again.If successfully decoded, phase is seized with no
Than propagation delay time at this time increases a URLLC slot length plus an eMBB slot length.Which may insure most
Small propagation delay time, but since possible secondary decoding can cause additional power consumption.
Mode 2：UE will continue to the eMBB business datums seized by URLLC business in eMBB time slots N+2, then with
EMBB time slots N is decoded again together.Compared with no seize, it is long that propagation delay time at this time increases a URLLC time slot
Degree adds an eMBB slot length.Which average delay compared with mode one is longer.
Mode 3：UE can according to the MCS of the ratio, eMBB business that eMBB business datums are seized by URLLC business and again
It passes number and formulates a rule, when meeting the rule, decoded with mode 1, otherwise mode 2 is used to decode.Such as：For different
MCS, number of retransmissions give the thresholding for the ratio that eMBB business datums are seized by URLLC business, when eMBB business datum quilts respectively
When the ratio that URLLC business is seized is less than the thresholding, UE is completed after the data for having received eMBB time slots N according to instruction is seized
Decoded success rate is higher, and employing mode 1 decodes, and otherwise employing mode 2 decodes.It can also be by the way of fairly simple, only
The thresholding that the ratio that eMBB business datums are seized by URLLC business is given according to MCS or number of retransmissions, can also give a system
The thresholding for the ratio that one eMBB business datums are seized by URLLC business.
