NR (new radio)
3GPP has had been approved by " Study on New Radio Access Technology " recently, is for studying
The research project of the next generation/5G radio access technologies, and have been based on it and started about frame structure, the channel for NR
Coding and modulation, the discussion of waveform and Multiple Access scheme.
NR need to design so as to meet various requirement using scene that be directed to respective subdivision and detailed and with
LTE/LTE is advanced to compare more improved data transfer rates.Specifically, enhancing mobile broadband (eMBB), extensive MTC (mMTC) and
Super reliable low delay communication (URLLC) has been suggested uses scene for the representativeness of NR, and needs design than LTE/LTE high
The more flexible frame structure of frame structure of grade is as the method for meeting the respective requirement using scene.
Specifically, consider to use scene by the representativeness of 3GPP, eMBB, mMTC and URLLC NR discussed.Due to respective
Had using scene and required for the different of data rate, delay and covering, so needing for based on different parameter set (examples
Such as, subcarrier spacing, subframe, TTI, etc.) be used as efficiently efficiently to multiplex the scheme of radio resource unit
Meet the method for the respective requirement using scene for the frequency band by constituting predetermined NR systems.
As the method for it, has been carried out and TDM, FDM or TDM/FDM are based on by a NR carrier wave about one kind
To multiplex and support the method with the parameter set of different subcarrier spacing (SCS) values and in the time domain configuration schedules unit
The discussion of the method for the middle one or more time quantums of support.About in this point, subframe is made as a kind of time domain in NR
The definition of structure, and determination will include the normal CP expenses based on 15kHz subcarriers spacing (SCS) (it is identical with LTE)
The single sub-frame durations of 14 OFDM symbols be defined as the reference parameter sets for defining corresponding sub-frame duration.
Therefore, the subframe in NR has the duration of 1ms.However, unlike LTE, since NR subframes are absolute reference duration, institute
Time quantum is can be defined as with time slot and mini-slot, which is actual uplink link/down link data scheduling
Basis.In this case, the quantity, that is, y values for constituting the OFDM symbol of corresponding time slot are defined as 14 value, without
How is pipe parameter set.
Therefore, predetermined time slot may include 14 symbols.Whole in symbol can be used for the hair according to corresponding time slot
The downlink in direction is sent to send (DL transmissions) or uplink transmission (UL transmissions), or can be with DL part+(gap)+UL
Partial form uses.
In addition, in predefined parameter collection (or SCS), the more smallest number of the quantity including the symbol than corresponding time slot is defined
Symbol mini-slot.Based on it, it is polymerize by time slot, can be arranged for uplink/downlink data transmission/reception
Short Time Domain scheduling interval, or can be arranged for uplink/downlink data transmission/reception it is long when domain scheduling between
Every.
Specifically, in the case of transmission/reception of the delay critical data of such as URLLC, when based on such as 15kHz
Small SCS values the unit of the time slot of 0.5ms (7 symbols) or 1ms (14 symbols) that defines in the frame structure of parameter set in
When executing scheduling, it may be difficult to meet delay requirement.Therefore, the OFDM symbol including more smallest number compared with corresponding time slot
Mini-slot can be defined, and can dispatch the delay critical data such as URLLC based on defined mini-slot.
Alternatively, as described above, by supporting one via the multiplexing in TDM schemes or FDM schemes
The parameter set with different SCS values in carrier wave, it is contemplated that based on the time slot (or mini-slot) defined for each parameter set
The method that length dispatches data according to delay requirement.For example, as shown in Figure 1, SCS correspond to 60kHz the case where, with
The case where SCS is corresponding to 15kHz is reduced to about 1/4 compared to the symbol lengths of length.Therefore, when a time slot includes equably
When 7 OFDM symbols, the corresponding slot length of 15kHz is 0.5ms, and the slot length of 60kHz is reduced to about
0.125ms。
As described above, it by defining different SCS or different TTI length in NR, has carried out about satisfaction
The discussion of method in each of URLLC and eMBB.
Transmission block configures
In LTE system, when sending distribution PDSCH/PUSCH resources for predetermined LDL/UL data, for passing through correspondence
The transport block sizes (TBS) that send of PDSCH/PUSCH be based on MCS and resource block (RB) and distribute information to determine.When corresponding
When TBS is determined, corresponding TB is divided (segmentation) at multiple code blocks (CB) according to the maximum CB sizes for coding, passes through
It is attached CRC in the unit of corresponding CB to encode, and between CB staggeredly, leads to the PDSCH/PUSCH for distribution
The mapping of resource.However, being executed in the unit of TB for the HARQACK/NACK feedbacks of predetermined PDSCH/PUSCH and according to it
Repeating transmission send operation.
In NR, the resource of the bigger for TBS is needed compared to LTE due to eMBB, so the CB of one TB of configuration
Quantity may acutely increase according to the definition of maximum CB sizes.Therefore, it is necessary to further segment the HARQ for a TB
ACK/NACK feeds back and retransmits the unit sent, and proposes based on the code block generated by being grouped one or more CB
The HARQ ACK/NACK feedbacks of group (CBG) and repeating transmission are sent or the HARQ ACK/NACK in the unit of CB are fed back and repeating transmission is sent
Needs.
In view of such situation, the present disclosure presents when UE and BS sends/receive data when configuration code block group
Close the technology with transmission data.
The embodiment being described below can be applied to UE, BS and the core network reality using all mobile communication technologies
Body (MME).For example, the present embodiment may be applied to next generation mobile communication (for example, 5G mobile communication or new RAT) UE,
BS and core-network entities (access and mobility functions (AMF)) and the mobile communication UE for being applied to LTE technologies.For ease of
Description, BS can indicate eNB or BS (CU, DU or a logic by CU and DU of the LET/E-UTRAN in 5G wireless networks
The entity that entity is realized), wherein central location (CU) and distributed unit (DU) is separated, i.e. gNB.
Meanwhile in NR using in scene, " URLLC " refers to supporting the service of high reliability and low delay, and can be
During data transmission/receive process generate delay (although send/receive data it is little) when there is a situation where serious problems
It is lower to be used.For example, becoming prodigious in data transmission/reception delay, such as in the case of automatic driving vehicle, such as
Danger of the fruit due to traffic accident and there are Loss of Life and property can then be serviced using URLLC.
EMBB can be used when needing by supporting service transmission/reception mass data of high-speed data transmission
Service.For example, when needing to send mass data (such as 3D videos or UHD service) per unit time, eMBB services can be by
It uses.
MMTC can be when send/receive data size less and postpone to lead to the problem of not be but needs it is low
The service used when power consumption.For example, being mounted to the sensor device of structure small city can be serviced using mMTC, because setting
It is standby should be with the battery long-time operation of insertion.
Hereinafter, the operation of the UE and BS according to the present embodiment will be described with reference to the drawings.
Fig. 2 is the figure of the operation for describing UE according to the embodiment.
With reference to figure 2, UE can execute the information that the maximum quantity about code block group (CBG) is received from BS in S210
Step.The information of maximum quantity about code block group includes about can be contained in a transmission code block group in the block
The information of maximum quantity, because transmission block is divided into multiple code blocks and one or more code blocks are configured to code by UE
In block group.
The maximum number about code block group can be received by UE specific higher layers signaling or honeycomb specific higher layer signaling
The information of amount.For example, the information of the maximum quantity about code block group can be UE technically or honeycomb is exclusively through RRC
What signaling received.
UE can be executed in S220 to be divided into N number of code block (wherein, N is natural number) by transmission block and is drawn N number of
The code block divided is grouped into M code block group the step of (wherein, M is natural number) carrys out configuration code block group.For example, UE can be with
A transmission block for being configured for data transmission is divided into N number of code block.Hereinafter, UE can will be N number of divided
Code block, which is grouped into M code block group, carrys out configuration code block group.
For example, code can be determined based on the relatively decimal between the maximum quantity of code block group and the quantity N of code block
The quantity M of block group.Specifically, UE can select the maximum quantity of the code block group received from BS and transmission block to be divided into
Smaller value between the quantity N of code block and the quantity of code block group can be determined as less than or equal to selected value
Value.For example, when the maximum quantity of code block group is configured as 3 and is received and working as the quantity of divided code block and being
When 10, UE can select the quantity of code block group as one in the natural number equal to or less than 3.That is, the number of code block group
Amount can be one in 1,2 and 3.
In another example, UE can be based on the value by obtaining the quantity of the quantity of code block divided by code block group
Come determine the every code block group being contained in each code block group code block quantity.For example, being determined when by the above method
When the quantity of code block group, UE can be based on by by the quantity (N) of the code block divided divided by identified code block group
Quantity (M) and the value that obtains determines the quantity for the code block being contained in each code block group.
For example, when the quantity for the code block being contained in each code block group is determined, among M code block group
The quantity of the code block for the every code block group for including in each of K code block group of head based on code block group index can be by
It is determined as the value obtained by rounding up to the value by obtaining the quantity of the quantity of code block divided by code block group.
Specifically, when the quantity N of code block is 10 and the quantity M of code block group is confirmed as 3, UE can execute grouping so that 4
A code block is contained in the K code block group based on code block group index.For example, 4 can be user's journey ceil (N/M)
And the value determined.
In another example, when the quantity for the code block being contained in code block group is determined, M code block group it
In each of the residue code block group other than K code block group in include every code block group code block quantity
It can be determined that by being obtained by the downward rounding of value for obtaining the quantity of the quantity of code block divided by code block group
The value obtained.Specifically, when the quantity N of code block is that the 10 and quantity M of code block group is confirmed as 3, UE can be executed point
Group is so that 3 code blocks are contained in the remaining M-K generation other than the K code block group based on above-mentioned code block group index
In code block group.For example, 4 values that can be determined for user's journey ceil (N/M).For example, 3 can be user journey floor (N/
<M the value) determined.
Meanwhile in the embodiment above, K is confirmed as by the quantity M by the quantity N of code block divided by code block group
The remainder of acquisition.For example, when N is 10 and M is 3, K can be determined that 1.
That is, when the quantity of code block is 10 and the quantity of code block group is confirmed as 3, UE can be executed control so that
4 code blocks are contained in 1 code block group based on code block group index and 3 code blocks are contained in remaining 2
In code block group.That is, code block can be grouped so that 4 code blocks are contained in code block group index 0, and 3 generations
Code block is contained in each of code block group index 1 and 2.
Meanwhile when the quantity for the code block that be contained in each code block group is determined, UE determine code block and
Code block group is to include code block.
For example, the quantity of the code block based on code block group index and per code block group, controller 510 can be according to code
N number of code block is assigned to M code block group and is grouped N number of code block by the sequence of block index.Specifically, when 10 code block quilts
When being grouped into 3 code block groups, code block is sequentially contained in code block group by the sequence that UE groups are indexed according to code block.
With reference to figure 3, code block index CB#0 to CB#3 is the group in code block group #0 to be contained in, code block index
CB#4 to CB#6, which is grouped into, to be contained in code block group #1, and code block index CB#7 to CB#9 be grouped by comprising
In code block group #2.
By operating above, according to above-described embodiment, transmission block can be divided into multiple code blocks and will be divided by UE
Code block be grouped into each code block group.
UE can execute the step of transmission block transmission data by being configured by code block group in S230.For example, UE will
CRC is attached to each code block, code block is grouped into code block group, and send transmission block.BS can be controlled in code
The execution that HARQ operation and repeating transmission in block group unit are sent.
Therefore, though transmission block is configured as growing very much on a timeline but if can carry out high speed data processing because
HARQ operation is executed in code block group unit and operation is sent in repeating transmission.
Hereinafter, by the operation based on BS operation descriptions in the case where down link data is sent to UE by BS.
Fig. 4 is the figure for describing BS operations according to the embodiment.
With reference to figure 4, BS can be executed in S400 to be sent to UE about the information of the maximum quantity of code block group (CBG)
The step of.BS can will be sent to UE about the information of the maximum quantity of the code block group determined according to predetermined criterion.For example, closing
It can be sent by UE specific higher layers signaling or honeycomb specific higher layer signaling in the information of the maximum quantity of code block group.
BS can be executed in S410 to be divided into N number of code block (wherein, N is natural number) by transmission block and is drawn N number of
The code block divided is grouped into M code block group the step of (wherein, M is natural number) carrys out configuration code block group.
As described above, BS can be smaller between the maximum quantity based on code block group and the quantity N of code block
It counts to determine the quantity M of code block group.For example, BS can be divided with the maximum quantity and transmission block of the code block group of option and installment
