The optional symbols of URLLC are possible to can be seldom, can not be seized so as to cause URLLC, causes the delay of URLLC business to increase, drop
Meaning caused by behavior itself is seized in low introducing.In addition, the resource for being not used in transmission RS can be used for seizing by URLLC, that
URLLC needs to know the RS configurations of current eMBB user；For URLLC, additional signaling overheads is needed so that receive
It is opaque.
Forbid seizing assemble of symbol by configuring in technical solution of the present invention, it is ensured that the sign resources in the set are not
It can be seized by URLLC business, thereby may be ensured that the sign resources for forbidding seizing in assemble of symbol can be normal by eMBB business
It uses, to ensure that the performance of eMBB business, reduces URLLC business and seize the influence to eMBB service features；In addition, not permitting
Perhaps the resource granularity that URLLC business is seized is symbol, and the resource distribution of the reference signal without knowing eMBB business ensures
URLLC business can rob the quantity of the resource accounted for, to ensureing that URLLC business can be executed normally.
To make the above purposes, features and advantages of the invention more obvious and understandable, below in conjunction with the accompanying drawings to the present invention
Specific embodiment be described in detail.
Fig. 1 is a kind of flow chart of business method for pre-emptively of the embodiment of the present invention.
Business method for pre-emptively in the present embodiment can be used for base station side.
Business method for pre-emptively shown in FIG. 1 may comprise steps of：
Step S101：When URLLC business seizes eMBB business, in each downlink unit transmission list of the eMBB business
In member, the URLLC business is dispatched in the sign resources for forbidding seizing except assemble of symbol and is seized, it is described to forbid seizing
Assemble of symbol is preconfigured；
Step S102：URLLC business datums are sent using the sign resources accounted for are robbed.
In the present embodiment, eMBB business and URLLC business can be two kinds of communication scenes.Wherein, eMBB business can carry
For the big flows mobile broadband service such as more high bandwidth, such as ultra high-definition video；URLLC business can meet various real-time communication need
It asks, and reliability higher, such as unmanned, industrial automation business.Specifically, eMBB business and URLLC business can be with
It realizes, can also be realized in different base station side in same base station side.
In order to ensure the low time delay of URLLC business, when eMBB business carries out, URLLC business can seize eMBB business
Running time-frequency resource.Specifically, the maximum belt that the maximum bandwidth (namely system bandwidth) that URLLC business occupies is occupied with eMBB business
Under wide (namely system bandwidth) unanimous circumstances, it may occur that seize.Specifically, the URLLC business seized can correspond to list
A URLLC user equipmenies can also correspond to multiple URLLC user equipmenies.Similarly, the eMBB business being preempted can correspond to individually
EMBB user equipmenies can also correspond to multiple eMBB user equipmenies.
It will be apparent to a skilled person that eMBB user equipmenies can be the user equipment using eMBB business；
URLLC user equipmenies can be the user equipment using URLLC business.
In specific implementation, forbid seizing assemble of symbol being that base station is configured in advance, can also be agreement (namely
Communication standard or communication protocol) it is specified.Then in step S101, when URLLC business seizes eMBB business, in the eMBB
In each downlink unit transmission unit of business, the URLLC is dispatched in the sign resources for forbidding seizing except assemble of symbol
Business is seized.Specifically, downlink unit transmission unit represents minimum data transmission time, it is referred to as transmission time
It is spaced (Transmission Time Interval, TTI).It, can be in each downlink unit transmission unit of eMBB business
Scheduling URLLC business is seized in the sign resources for forbidding seizing except assemble of symbol, and eMBB business is forbidding seizing symbol
Collect the business closed to be unaffected.
For example, eMBB business downlink unit transmission units are a subframe namely 14 sign resources, forbid seizing symbol
Collection is combined into the 3rd and the 4th symbol, then URLLC business can be accounted in the 1st, the 2nd, the 5th to the 14th enterprising rob of symbol, and
Business of the eMBB business on the 3rd and the 4th symbol is unaffected.Further, the first two symbol in each subframe
(namely the 1st and the 2nd symbol) region, remaining symbol are data area in order to control, and URLLC business, which is seized, will not usually seize control
Region processed, then URLLC business can be accounted in the 5th to the 14th enterprising rob of symbol.
In specific implementation, after the completion of seizing, in step s 102, the sign resources robbed and accounted for can be utilized to send URLLC
Business datum.That is, being set at least one URLLC user using the sign resources accounted for transmission URLLC business datums are robbed
It is standby.
The embodiment of the present invention forbids seizing assemble of symbol by configuring, it is ensured that sign resources in the set will not be by
URLLC business is seized, thereby may be ensured that forbid seizing sign resources in assemble of symbol can by eMBB business normal uses,
To ensure that the performance of eMBB business, reduces URLLC business and seize the influence to eMBB service features；In addition, not allowing
The resource granularity that URLLC business is seized is symbol, and the resource distribution of the reference signal without knowing eMBB business ensure that
URLLC business can rob the quantity of the resource accounted for, to ensure that URLLC business can be executed normally.
Preferably, can also include after step S102：It sends resource and seizes instruction information to eMBB user equipmenies, with logical
Know the position that the sign resources accounted for are robbed described in the eMBB user equipmenies.
In specific implementation, after the completion of seizing, instruction information can be seized by resource, URLLC business is robbed to the symbol accounted for
The position informing eMBB user equipmenies of number resource.Since rob the sign resources accounted for transmission is URLLC business datums, lead to
The position that notice eMBB user equipmenies rob the sign resources accounted for is crossed, can make eMBB user equipmenies that can be seized to avoid demodulation
To sign resources on URLLC business datums, to avoid eMBB service features deteriorate and BLER(block error rate) increase.
Further, the eMBB user equipmenies are seized after receiving the resource and seizing instruction information by described
To sign resources on the data bit log-likelihood ratio that carries reset.Specifically, eMBB user equipmenies are robbed receiving resource
It accounts for before instruction information, the data bit log-likelihood ratio carried on each symbol in downlink unit transmission unit can be demodulated
(Likelihood Rate,LLR).For example, demodulating the data bit pair carried on each symbol in downlink unit transmission unit
Counting likelihood ratio is：{LLR1 3, LLR2 3..., LLRn3 3,LLR1 4, LLR2 4..., LLRn4 4,…,LLR1 14, LLR2 14...,
LLRn14 14}.Wherein, LLRn lIt is the bit number for including on first of symbol for n-th of the LLR solved on first of symbol, nl.By
In corresponding reference signal may be carried on symbol, the data bit number of distinct symbols is caused to have difference.Assuming that URLLC business
Symbol 8,9,12,13 is seized, the eMBB bits of traffic data LLR in then symbol 8,9,12,13 is invalid, then eMBB user equipmenies exist
It receives resource to seize after instruction information, eMBB user equipmenies reset the bit LLR on symbol 8,9,12,13, i.e. { LLR1 8=
0, LLR2 8=0 ..., LLRn8 8=0, LLR1 9=0, LLR2 9=0 ..., LLRn9 9=0, LLR1 12=0, LLR2 12=0 ...,
LLRn12 12=0, LLR1 13=0, LLR2 13=0 ..., LLRn13 13=0 }, it is then fed into decoder.
Further, transmission resource is seized instruction information to eMBB user equipmenies and be may comprise steps of：Described in determination
EMBB user equipmenies are in the first frequency resource location robbed in the sign resources accounted for and the URLLC business datums
In the second frequency resource location robbed in the sign resources accounted for；If the first frequency resource location and described second
Frequency resource position, which exists, to be overlapped, then sends the resource and seize instruction information to the eMBB user equipmenies.
In specific implementation, Fig. 2 is can refer to, Fig. 2 is a kind of application scenarios signal of business method for pre-emptively of the embodiment of the present invention
Figure.Wherein, time-domain symbol is laterally indicated, it is longitudinal to indicate frequency domain bandwidth.Each downlink unit transmission unit of eMBB business includes
14 symbols.In the system bandwidth f1-f4 of eMBB business, there are three user equipmenies：EMBB user equipmenies 1, eMBB user equipmenies
2 and eMBB user equipmenies 3, and certain bandwidth is occupied respectively.
After the completion of seizing, URLLC business is robbed in the time domain accounts for symbol 7, symbol 8, symbol 11 and symbol 12 (in such as figure
Shown in dash area).For eMBB user equipmenies 1, first frequency resource location is f1-f2, and URLLC business is in symbol 7, symbol
Second frequency resource location on numbers 8 frequency domain is f1-f5, and first frequency resource location and the second frequency resource location are deposited
It is overlapping, then can send resource and seize instruction information to eMBB user equipmenies 1,1 symbol 7 of notice eMBB user equipmenies, symbol 8
It is preempted.
Further, on 8 frequency domain of symbol 7 and symbol, URLLC business occupy eMBB user equipmenies 1 bandwidth and
A part for the bandwidth (f2-f3) of eMBB user equipmenies 2；On 12 frequency domain of symbol 11 and symbol, URLLC business occupies eMBB and uses
A part for the bandwidth (f3-f4) of family equipment 3.In this case, even if URLLC business occupies the band of eMBB user equipmenies 2
A part for the bandwidth of a wide part and user equipment 3, but seized in instruction information in resource and can also indicate that eMBB user
2 symbol 7 of equipment and symbol 8 are preempted, and 3 symbol 11 of instruction eMBB user equipmenies and symbol 12 are preempted.So, eMBB user sets
Standby 2 in demodulation, abandons the total data on symbol 7 and symbol 8, and eMBB user equipmenies 3 abandon symbol 11 and symbol in demodulation
Total data on numbers 12.
Preferably, it may comprise steps of before step S101：Forbid seizing all symbols in assemble of symbol by described
The position of number resource is sent to the eMBB user equipmenies.Specifically, if forbidding seizing assemble of symbol being that base station is matched in advance
It sets, then the position for forbidding seizing all sign resources in assemble of symbol can be sent to the eMBB user by base station sets
It is standby.If forbidding seizing assemble of symbol being that agreement is specified, eMBB user equipmenies, which have learned that, to be forbidden seizing in assemble of symbol
The position of all sign resources, is informed without base station.
Further, the bit number that the resource is seized shared by instruction information is equal to：The downlink unit of the eMBB business
Sign resources sum shared by transmission unit and the difference for forbidding seizing all sign resources sums in assemble of symbol.This implementation
Example by the position for forbidding seizing all sign resources in assemble of symbol by informing eMBB user equipmenies, so that resource is seized
Indicate that the bit number shared by information can be reduced, to reduce signaling overheads.
Specifically, by taking downlink unit transmission unit occupies 14 symbols as an example, if eMBB user equipmenies cannot be known
Forbid seizing the position of all sign resources in assemble of symbol, then resource seize instruction information need 14 bits, each bit with
Each symbol is corresponding.If eMBB user equipmenies know that the position for forbidding seizing all sign resources in assemble of symbol is the 3rd
With the 4th symbol, then resource, which is seized, indicates that information needs 12 bits, each bit and the 1st, the 2nd, the 5th to the 14th symbol phase
It is corresponding.
Closer, the bit number that the resource is seized shared by instruction information is equal to：The downlink list of the eMBB business
Sign resources sum shared by the transmission unit of position forbids seizing all sign resources sums and control in assemble of symbol described in subtracting
Sign resources sum shared by region processed.By taking downlink unit transmission unit occupies 14 symbols as an example, downlink unit transmission unit
The first two symbol region, URLLC business do not seize control area usually in order to control.Therefore if eMBB user equipmenies know taboo
The position for only seizing all sign resources in assemble of symbol is the 3rd and the 4th symbol, then resource, which is seized, indicates that information only needs 10
Bit, each bit are corresponding with the 5th to the 14th symbol.
Preferably, the downlink of the time span and the URLLC business of the downlink unit transmission unit of the eMBB business
The time span of unit transmission unit is identical or different.For example, the downlink unit transmission unit of eMBB business occupies 10ms,
The downlink unit transmission unit of URLLC business occupies 5ms.
Preferably, described to forbid seizing assemble of symbol including at least the occupied symbol money of advance data demodulated reference signal
Source.
Closer, forbid seizing assemble of symbol only including the occupied symbol money of advance data demodulated reference signal
Source.
Specifically, assemble of symbol where advance data demodulated reference signal (Front-loaded DMRS) does not allow
URLLC business is seized；In the reference signal of assemble of symbol where other reference signals, such as additional DMRS, phase noise
(Phase tracking reference signal, PT-RS), channel state information reference signals (Channel state
Information reference signal, CSI-RS) where assemble of symbol on allow URLLC business seize.Due to preceding
It sets data demodulation reference signal and usually only takes up 1 to 2 symbols, and URLLC business is in each downlink unit transmission of eMBB business
Data area can normally be seized in unit, therefore can ensure the URLLC business time delay influence suffered when seizing as far as possible
It is small.In addition, advance data demodulated reference signal can be used for the demodulation of eMBB user equipmenies, by ensureing advance data demodulation
The occupied sign resources of reference signal are not seized by URLLC business, to ensure that eMBB user equipmenies can be demodulated normally, into
And it ensure that the performance for seizing eMBB business under scene.
