Specific embodiment
Below in conjunction with attached drawing, the technical solution in the application is described.
In LTE system, downlink and uplink is based respectively on OFDMA and SC-FDMA, and running time-frequency resource is divided into time dimension
On OFDM or SC-FDMA symbol (hereinafter referred to as time-domain symbol, abbreviation symbol) and frequency dimension on subcarrier.And it is the smallest
Resource granularity is called a resource unit (Resource Element, RE), i.e., expression time-domain on a time-domain symbol and
The time-frequency lattice point of a sub- carrier wave composition in frequency domain.
The transmission of business is dispatched based on base station in LTE system.The data packet on upper layer quilt when physical layer is scheduled
The small data packets with transmission block (Transport Block, TB) for unit are divided into, the basic time unit of scheduling is usually one
A subframe, Shi Changwei 1ms.One subframe includes two time slots, and a time slot includes 7 time-domain symbols.Further, LTE is drilled
Into further accounting for introducing shorter time scheduling unit in system, for example, as unit of a time slot even several time-domain symbols
Scheduling mode.In general, specific scheduling flow is that base station sends down control channel, carried on the down control channel
The scheduling information of transmission block TB in downstream data channel or uplink data channels.Wherein, scheduling information includes the money of scheduled TB
Source distribute information (that is, occupy running time-frequency resource), modulation and encoding scheme (Modulation and Coding Scheme,
MCS) the control such as index information.
Wherein, the size (Transport Block Size, TBS) of transmission block is the important step of downstream transmission.Base
After station has configured TBS, TBS information is carried in MCS index and the resource allocation information in DCI.U blind examination DCI, according to it
In resource allocation information and MCS index, extrapolate TBS.The hair of upstream data is carried out further according to resource allocation information therein
It send or the reception of downlink data.
In existing LTE system, the determination of TBS, is solely dependent upon MCS and base station is the Physical Resource Block PRB of terminal distribution
Quantity (hereinafter referred to as NPRB)。
Specifically, for no special subframe, including under frequency division duplex (Frequency Division Duplex, FDD)
Subframe and time division duplex (Time Division Duplex, TDD) under normal sub-frames.
Terminal device first passes through MCS index, looks into MCS table (such as table 1) and obtains TBS index, further according to TBS index and from money
The number of the assigned PRB determined in information is distributed in source, is looked into TBS table (such as table 2) and is obtained TBS.
Table 1
| MCS index | Order of modulation | TBS index |
| 0 | 2 | 0 |
| 1 | 2 | 1 |
| 2 | 2 | 2 |
| 3 | 2 | 3 |
| …… | …… | …… |
Table 2
For the special subframe under TDD, including descending pilot frequency time slot (being denoted as DwPTS), guard time (Guard
Period, GP) and three parts of uplink pilot time slot (being denoted as UpPTS).LTE currently supports 10 kinds of different special subframes to match
It sets, the DwPTS length (that is, time-domain symbol number) under difference configuration is also not quite similar.DwPTS length can be equal to 8~12
Symbol.In addition to this, DwPTS is also possible to only grow 3 symbols, is not used in transmission downlink data at this time.
For special subframe, terminal device first uses method same as above, is tabled look-up by MCS index and 1 obtains TBS rope
Draw.Then it is tabled look-up according to PRB (hereinafter referred to as equivalent PRB) number after TBS index and conversion and 2 obtains TBS.Wherein, equivalent PRB
It can be calculated by following formula (1):
The process that TBS is calculated when carrying data from DwPTS above can be seen that the time domain that LTE system considers DwPTS
Symbol is fewer than the time-domain symbol of no special subframe, therefore is configured with 0.75 this parameter and converts to the quantity of the PRB of distribution, then
TBS is calculated according to the PRB after conversion.But no matter 8 symbols of DwPTS long or 12 symbols, the parameter of configuration are 0.75, spirit
Activity is poor.
And 5G technology is to support more flexible time slot configuration.For example, the time slot of mini-slot mini-slot, 7 symbols,
The time slot etc. of 14 symbols.Simultaneously as will support the flexible of reference signal (Reference Signal, RS) in 5G technology
Configuration, this is configurable the quantity for the RE that carrying data are actually used on each PRB also.It is understood, therefore, that
It is very big for carrying the dynamic range of the quantity of the RE of data on each PRB in 5G.For example, from 24~120.If continued
It is no longer suitable that TBS is calculated in a manner of tabling look-up in LTE above.
In order to be adapted with 5G, a kind of existing scheme proposition use following formula (2) calculating TBS:
Wherein, υ is the spatial reuse number of plies of TB mapping, and Q is the order of modulation of modulating-coding strategy, and R is code rate, NPRBFor
The quantity of the PRB distributed on frequency domain,It is in a PRB for carrying the quantity of the RE of data.
Q and R can be determined according to such as the following table 3.
Table 3
| MCS index | Order of modulation Q | Code rate R × 1024 |
| 0 | 2 | 120 |
| 1 | 2 | 193 |
| 2 | 2 | 308 |
| 3 | 2 | 449 |
| …… | …… | …… |
As mentioned before, it is contemplated that 5G will support a variety of slot lengths, and therefore, someone is on the basis of this scheme, again
Propose following several implementation
Mode 1
It provides singleDefault value.
Mode 2
It is multiple for different PDSCH length legislationsDefault value.
Mode 3
Network side is that each UE configures one
Mode 4
Network side is that each UE configures oneValue set, indicate that current data are transmitted by DCI every time and adopt
?
Mode 5
Network side is that UE configures oneValue set, every time by for UE indicate it is one " falseness " and smallerMeet the requirement of the ELF magnetic field under URLLC scene.
For example it is assumed that high-level signaling is some terminal equipment configurationValue set
The quantity that the RE of carrying data is actually available in time slot 1, each PRB is 120.It is actually available in time slot 2, each PRB
In carrying data RE quantity be 80.In time slot 1, if the code rate of URLLC business demand is lowest bit rate in table 3 above
Half, then base station to the terminal device by indicatingRealize the configuration of low bit- rate.But in time slot 2, if
The code rate of URLLC business demand remains as the half of lowest bit rate in table 3, since high-level signaling does not return frequent transmission, base
Station has little time to change preconfiguredSet in value, therefore, base station can not be the terminal equipment configuration on demand
As it can be seen that although the above several ways are intended to meet, the following 5G system multi-slot length, TBS is more flexible wants
Ask, but in view of in 5G for carry data RE Number dynamics range greatly, high-level signaling will not frequently send, URLLC
The numerical value for the low bit- rate that may be needed extremely low code rate, and specifically need is unable to estimate and in view of forward compatibility etc. is many
Reason, these existing modes are still unable to satisfy demand.
For this purpose, the application proposes a kind of method for transmitting data, the quantity that the RE of data is carried in 5G system can satisfy
Dynamic range is very big, URLLC business may need ELF magnetic field, has the demands such as forward compatibility, realizes in multi-slot length
Scene under, can be any low bit- rate of UE flexible configuration.

Subsequent, the network equipment can be the value set of terminal equipment configuration Dynamic gene, the adjustment by high-level signaling
The value set of the factor is the subset of Dynamic gene resource pool.
For example it is assumed that the value set of the Dynamic gene={ 0.5,0.6,0.7,1 }.
The network equipment can indicate the value set of the Dynamic gene by 2 bits.For example, passing through " 00 ", " 01 ", " 10 "
" 11 " indicate respectively that the value of Dynamic gene is 0.5,0.6,0.7 and 1.
In the embodiment of the present application, the value set of the Dynamic gene of network equipments configuration can be related with MCS.In other words
It says, it can be for the value set of the different Dynamic gene of different MCS index configurations.

Son.
Table 4
| MCS Group | 0 | 1 | … | M |
| Set ofη | {η0,0,…,η0,k} | {η1,0,…,η1,k} | {ηM,0,…,ηM,k} |
According to different MCS modes, different values is configured for Dynamic gene, running time-frequency resource can be saved.
For example, in SNR=-3dB, to reach BLER=10^-5, the code rate needed is 0.12.In SNR=
When 0.2dB, to reach BLER=10^-5, the code rate needed is 0.25.In SNR=3.3dB, to reach BLER=10
^-5, the code rate needed are 0.5.
The value of Dynamic gene needed for above-mentioned three kinds of MCS modes are corresponding may refer to table 5.
Table 5
As it can be seen that MCS index 1 and index 3 may make up same since the value of corresponding Dynamic gene is same or similar
MCS group, and MCS index 4 belongs to different MCS group from index 1, index 3.
It is exemplified below and configures the different values of Dynamic gene are how to save transmission money according to different MCS modes
Source.
Base station is to dispatch 6PRB, MCS index 1, η=1, the service of error rate 10% UE#1.To dispatch 6PRB, MCS index 4, η
=1, error rate 10% services UE#2.After URLLC business reaches, need lower error rate to 10^-5.At this point, base station withMCS index 1, η=0.6 service UE#1,MCS index 4, η=0.83 service UE#2.With
η is all configured to 0.6 and compares, and UE#2 has saved the downlink transfer resource of 2 PRB.
In the embodiment of the present application, the value set of Dynamic gene can be predefined, or be passed through by the network equipment
High-level signaling instruction.For example, terminal device, which receives the network equipment, sends the first configuration information, first configuration information is for referring to
Show the value set of Dynamic gene.
240, terminal device determines the first TBS according to resource allocation information, MCS index and Dynamic gene.
In the embodiment of the present application, terminal device determines first according to resource allocation information, MCS index and Dynamic gene
TBS includes two ways.
Mode 1
Terminal device calculates the first TBS according to the following formula (3) or (4).
Wherein, NPRBThe quantity for being the PRB that the terminal device distributes for the network equipment,Or
For the quantity on a PRB in a time slot for bearing downlink, the RE of upstream data, ν is data channel mapping
The number of plies, QmFor order of modulation, R is code rate, ηDLAnd ηULThe respectively Dynamic gene that uses of downlink, uplink.
It should be understood that QmIt can look into MCS table according to MCS index and determine.
If it is downlink transfer, then formula (3) are used.If it is uplink, then formula (4) are used.
That is, the first TBS will be directly calculated according to formula (3) or (4) in terminal device in mode 1.
It is understood that the TBS in formula (3) and formula (4), is the first TBS.
Mode 2
Optionally, terminal device determines the first TBS according to resource allocation information, MCS and Dynamic gene, comprising:
Terminal device will calculate the 2nd TBS according to above-mentioned formula (3) or formula (4)；
Terminal device chooses the first TBS from TBS set according to the 2nd TBS.
It wherein, include at least one TBS in TBS set.
That is, the 2nd TBS that terminal device is calculated according to formula (3) or (4) is as an initial value, then
The first TBS is chosen from TBS set according to this initial value.
Wherein, the first TBS and the 2nd TBS meets the first mapping relations, and the first mapping relations can be configured by high-level signaling,
The embodiment of the present application is not construed as limiting this.For example, the first mapping relations can be as described in following any one:
First TBS is the value in TBS set closest to the 2nd TBS；
First TBS is the maximum value for being not more than the 2nd TBS in TBS set；
First TBS is the minimum value for being not less than the 2nd TBS in TBS set.
Similar with the value set of Dynamic gene, TBS set can be predefined, or pass through high level by the network equipment
Signaling instruction.
In some scenarios, TBS determination may not be needed excessively high flexibility.If the TBS of network equipments configuration is higher than
Actually required TBS can reduce the reliability of the coding of system instead, influence system performance.
For example, URLLC business, and the small data packets to be sent that URLLC business is handed down from upper layer are transmitted to UE in base station
A kind of this TBS of only 256bits (that is, 32bytes).At this point, if base station determines L PRB of scheduling, with MCS index N hair
It send, and having the TBS of mapping relations in TBS set with the TBS is (256+Z) bits.At this point, base station will first pass through the side of zero padding
Formula, it is (256+Z) bits that the data packet of 256bits, which is mended, then again with code rateSend data.
On the contrary, if TBS flexibility is less high, the network equipment is only configured with a kind of this TBS of 256bits, then base station will
Directly with code rateSend data.Demodulation performance is higher instead.
250, terminal device carries out receiving or sending for data channel with the network equipment according to the first TBS.
If it is downlink transfer, terminal device receives data channel according to the first TBS determined in step 240.
If it is uplink, terminal device carries out uplink data channels according to the first TBS determined in step 240
It sends.
