NR (New Radio)

3GPP recently approved the study item "Study on New Radio Access Technology" for research on next generation / 5G radio access technology, and based on this, RAN WG1 has frame structure, channel coding and modulation , waveform & multiple access scheme and so on. NR is required not only to improve data transmission rate as compared with LTE, but also to design various QoS requirements that are required according to granular and specific usage scenarios. In particular, enhancement mobile broadband (eMBB), massive MTC (MMTC) and URLLC (Ultra Reliable and Low Latency Communications) are defined as typical usage scenarios of NR. structure design is required. Since each usage scenario has different requirements for data rates, latency, reliability, coverage, etc., it is a method to efficiently satisfy the requirements of each usage scenario through frequency bands constituting an NR system. there is a need for an efficient multiplexing of radio resource units based on subcarrier spacing, subframe, TTI, etc., for example.

One method is to support TDM, FDM or TDM / FDM based multiplexing on one or more NR component carriers (s) for numerology with different subcarrier spacing values, and a scheduling unit in the time domain A discussion was made on how to support more than one time unit in composition. In this regard, NR is a type of time domain structure defined as a subframe. Reference numerology for defining the subframe duration is defined as 14 OFDM symbols of 15 kHz sub-carrier spacing (SCS) based normal CP overhead equivalent to LTE To define a single subframe duration. Thus, subframes in NR have a time duration of 1ms. However, unlike LTE, NR subframes are absolute reference time durations, and slots and mini-slots can be defined as time units that are the basis of actual uplink and downlink data scheduling. In this case, the number of OFDM symbols constituting the slot, y value is defined as y = 7 and 14 for the numerology having the SCS value of up to 60 kHz, and for the numerology having the SCS value larger than 60 kHz, y = Lt; / RTI >

Accordingly, any slot can be composed of 7 or 14 symbols, and all symbols are used for DL transmission according to the transmission direction of the corresponding slot, or all symbols are used for UL transmission, or the DL portion + (gap) + UL portion.

Also, a mini-slot composed of a smaller number of symbols than a corresponding slot is defined in an arbitrary numerology (or SCS), and a short-time time-domain scheduling interval is set for uplink / downlink data transmission or reception, A long-time time-domain scheduling interval for uplink / downlink data transmission and reception can be configured. In particular, in the case of transmission and reception of latency critical data such as URLLC, scheduling is performed in units of 0.5 ms (7 symbols) or 1 ms (14 symbols) based on a numerology-based frame structure having a small SCS value, such as 15 kHz , it is difficult to satisfy the latency requirement. Therefore, it is possible to define a mini-slot composed of a smaller number of OFDM symbols than the corresponding slot and to schedule the latency critical data such as the URLLC based on the defined mini-slot.

Alternatively, as described above, by supporting the numerology having different SCS values in one NR Carrier by multiplexing the TDM and / or FDM scheme, it is possible to reduce the number of slots based on the slot (or mini-slot) length defined for each numerology Scheduling of data according to latency requirement is also considered. For example, as shown in FIG. 1, when the SCS is 60 kHz, the symbol length is reduced to about 1/4 of that of the SCS 15 kHz. Therefore, when one slot is composed of 7 OFDM symbols, While the slot length based on 60 kHz is reduced to about 0.125 ms.

In this way, the NR is discussing how to satisfy the requirements of URLLC and eMBB by defining different SCSs or different TTI lengths.

NR PDSCH / PUSCH  TB, CB, CBG  Configuration

In the existing LTE system, when a PDSCH / PUSCH resource is allocated for an arbitrary DL / UL data transmission, the TBS (Transport Block Size) through which the PDSCH / PUSCH is transmitted is determined by MCS and RB (Resource Block) allocation information do. When the TB is determined, the TB is segmented into a plurality of CBs according to a maximum CB (code block) size for encoding, and the CRC is attached and encoded in the corresponding CB units. Mapping is performed for PDSCH / PUSCH resources. On the other hand, the HARQ ACK / NACK feedback and retransmission for an arbitrary PDSCH / PUSCH are performed in TB units.

In NR, especially in case of eMBB, since it is required to support larger TBS compared to LTE, the number of CBs constituting one TB can be drastically increased according to the maximum CB size definition. Therefore, there is a great need to further subdivide HARQ ACK / NACK feedback and retransmission units for one TB. A CBG (Code Block Group) is formed by grouping one or more CBs, and the corresponding CBG-based HARQ ACK / NACK feedback and retransmission or CB A need exists for HARQ ACK / NACK feedback and retransmission of the unit.

The present invention proposes a CBG configuration method for NR PDSCH / PUSCH and a control information transmission / reception method associated therewith.

Point 1. Dynamic or implicit CBG  number configuration

The number of CBGs constituting an arbitrary TB can be dynamically signaled via the DCI or implicitly defined.

Specifically, the number of CBGs for an arbitrary UE may be included in the DL assignment DCI or the UL grant DCI for transmitting the resource allocation information for the PDSCH or the PUSCH, and may be transmitted through the PDCCH.

Or as a function of the size of the TBS transmitted on any PDSCH or PUSCH, or as a function of the number of CBs determined by the TBS and the maximum CB size.

Or the size of the corresponding CBG can be determined according to the number of mini-slots or mini-slot groups constituting an arbitrary slot.

Or semi-static through UE-specific / cell-specific higher layer signaling for each terminal.

Or as a function of the number of CBGs set through the UE-specific / cell-specific higher layer signaling or L1 signaling through DCI and the number of CBs constituting the TBs transmitted on any PDSCH or PUSCH. For example, a CBG constituting the corresponding TB is determined based on a value equal to or smaller than the number of CBGs set through UE-specific / cell-specific higher layer signaling or L1 signaling and the number of CBs constituting the corresponding TB . That is, in a base station / network, when one PDSCH or PUSCH is transmitted for each UE through UE-specific / cell-specific higher layer signaling or L1 signaling, it can be configured for one TB transmitted through the corresponding PDSCH or PUSCH and the number of actual CBGs may be defined as a value less than or equal to the number of CBs constituting the TB and the maximum CBG number set by the base station / network.

Or a combination of parameters transmitted through UE-specific or cell-specific higher layer signaling and parameters transmitted through L1 control signaling such as DL assignment DCI or UL grant, the number and configuration of CBG for arbitrary TB have. Specifically, when establishing a CBG-based (re) transmission for a UE through UE-specific or cell-specific higher layer signaling, the base station / network determines the DL assignment DCI for the UE or the size of the CBG indication information area That is, the number of bits constituting the corresponding CBG indication information area is set, and the number of CBGs for TBs transmitted and received via the PDSCH or PUSCH allocated through the corresponding DL assignment DCI or UL grant is Can be defined to be set through the corresponding CBG indication information area. For example, if a CBG-based PDSCH or PUSCH (re) transmission setup is performed by a base station / network for an arbitrary terminal, the CBG indication information area configured through DL assignment DCI or UL grant for the corresponding terminal And may be a bitmap information area for indicating a CBG transmitted through a PDSCH or PUSCH transmission resource allocated through the corresponding DL assignment DCI or UL grant. Accordingly, the base station / network allocates the size of the bitmap information area for the corresponding DLG assignment DCI or UL grant for the corresponding UE through the UE-specific or cell-specific higher layer signaling, that is, the corresponding CBG indication The number of bits constituting the bitmap information area for the UE is defined so that the bit allocation size of the DL assignment DCI for the corresponding UE or the CBG indication information area included in the UL grant is determined. However, when a CBG-based (re) transmission for a PDSCH of an arbitrary terminal is set by the base station / network, the bitmap size of the CBG indication information area set through the corresponding UE-specific or cell- The size (eg, number of HARQ ACK / NACK feedback bits) of the HARQ ACK / NACK feedback information through the PUCCH or PUSCH of the corresponding terminal may be determined. When the CBG-based PDSCH or PUSCH (re) transmission for an arbitrary UE is established, the size of the CBG indication information area of the DL assignment DCI or UL grant for the corresponding UE is determined by UE-specific or cell-specific higher layer signaling When the PDSCH or PUSCH for the corresponding UE is set, the number of CBGs constituting the TB transmitted through the corresponding PDSCH or PUSCH transmits transmission resource allocation information for initial transmission of the corresponding PDSCH or PUSCH. The DL assignment DCI or the UL grant of the DL grant. For example, as described above, a CBG instruction information area included in a DL assignment DCI or an UL grant is configured as a bitmap type for CBG indication transmitted through a corresponding DL assignment DCI or a PDSCH or PUSCH allocated through an UL grant , When the initial PDSCH or initial PUSCH resource allocation for an arbitrary TB transmission is allocated, the number of CBGs constituting the TB through the bitmap-based CBG indication information area included in the corresponding DL assignment DCI or UL grant is implicitly It can be signaling. Specifically, in constructing the bitmap information area for CBG indication in the base station / network, the CBG transmitted through the corresponding DL assignment DCI or the PDSCH or PUSCH allocated by the UL grant is designated as '1', and CBG 0 'for the TB, a bitmap for the CBG indication of DL assignment DCI or UL grant including initial PDSCH or PUSCH resource allocation information for an arbitrary TB transmission, It is possible to define that the bits of the bitmap for indicating the CBG are composed of '1' from the LSB or MSB and the remaining bits (s) are composed of '0' as many as the number of CBGs.

Point 2. CB grouping method

Solution 1. CBG  segmentation first

For any TB, a primary segmentation is made to the CGB level, followed by segmentation to CB within the CBG.

That is, if the number of CBGs is set according to the above point 1, the corresponding TBGs can be divided into evenly divided or almost evenly divided CBGs according to the number of corresponding CBGs. If an evenly or almost evenly divided CBG is constructed for the TB of arbitrary PDSCH or PUSCH, the CB can be independently configured according to the maximum CB size within each CBG. If independent CB configuration is performed at CBG level, interleaving between CBs within each CBG can be performed, or mapping can be performed within allocated PDSCH or PUSCH resources without interleaving. Or interleaving may be established by the base station by UE-specific / cell-specific higher layer signaling or L1 control signaling.

2. CB segmentation first

Any TB that is transmitted on any PDSCH or PUSCH is firstly segmented into CB (s) evenly divided or almost evenly divided according to the maximum CB size, and CB (s) 1, CBG, CBG, and CBG. That is, when N CBs are configured from CB # 0 to CB # (N-1) for an arbitrary TB and M CBGs are set for the TB, CBG # 0 to CBG # (1) below, in constructing the CB constituting the above-mentioned CB.

Equation (1)

The arbitrary CBG # m (where m = 0, ..., M-1) is composed of CB # n satisfying the following expression.

However, [X] means the maximum integer not greater than X. That is, it means the maximum integer (floor function) among integers less than or equal to X. However, according to the above equation (1), in determining the CBs constituting the CBGs, CBs # 0 to # (M- 1). The present invention is not limited to the form of the determination formula, and all cases where the CB index is cyclically mapped to CBG in an increasing order of the CB index are included in the present invention.

For example, when N = 10 and M = 3, CBG # 0 = {CB # 0, 3, 6, 9}, CBG # 1 = {CB # CB # 2, 5, and 8}, the CBs are sequentially / cyclically mapped to each CBG in increasing order.

That is, in constructing the M CBGs, the first K CBGs are composed of ceil (N / M) CB (s) and the remaining (MK) CBGs are CB (s) . However, in this case, K = N mod M is defined. Or sequentially, the first K CBGs of the total M CBGs are sequentially assigned to the total Kceil (N / M) CBs from CB # 0 to CB # (Kceil (N / M) -1) (N / M) floor (N / M) to CB # (Kceil (N / M)) to CB # (N-1) (N / M) CBs (s) for CBs, respectively. CBG # 0 = {CB # 0,1,2,3}, CBG # 1 = {CB # 4,5,6}, CBG # 2 = CB # 7, 8, 9}.

Alternatively, a method of mapping CBs constituting an arbitrary CBG can be constructed by the following expression (2).

Equation (2)

The arbitrary CBG # m (where m = 0, ..., M-1) is composed of CB # n satisfying the following expression.

However, according to the above equation (2), each CBG is composed of consecutive [N / M] CBs, and the last CBG is composed of remaining CBs . In other words, CBG # 0 is composed of [N / M] CBs from CB # 0 to # [N / M] CBG # (M-1) is composed of [N / M] CBs and CBG # (M-1) Will be made up of remaining CBs.

In addition, the method of constructing CBs sequentially from the highest CBG index in the reverse order of the above formulas (1) and (2) is also included in the scope of the present invention.

In this case, as in the above-mentioned method 1, CB interleaving for PDSCH / PUSCH resource mapping may be performed in CBG units or TB units, or localized mapping may be applied without interleaving. Or the corresponding interleaving application and the CBG-based or TB-based interleaving mode may be set by the cell-specific / UE-specific higher layer signaling or L1 control signaling to the base station.

Point 3. PDSCH / PUSCH  resource mapping

Solution 1. CBG -specific resource mapping

A method of mapping the TB to be transmitted to the allocated PDSCH / PUSCH resource, which can be defined to perform resource mapping and rate matching for each CBG constituting the corresponding TB. That is, the corresponding PDSCH or PUSCH resource mapping can be defined to divide allocated PDSCH or PUSCH resources according to the number of CBGs, and define resource mapping and rate matching for each CBG in the divided PDSCH or PUSCH resource. At this time, the resource partitioning can be defined to be performed in the time domain. That is, for the TTI in which the PDSCH or PUSCH transmission is performed, resource mapping can be defined to be performed in units of symbol / symbol group / mini-slot / mini-slot group / slot / slot group evenly or almost evenly divided according to the number of CBG have. Alternatively, the resource partitioning can be done in the frequency domain. That is, the allocated PRB resources may be divided into evenly or almost evenly divided sub-bands according to the number of CBGs, and resource mapping and rate matching may be defined for each CBG in the corresponding sub-band. At this time, resource mapping of each CBG within the divided region can be mapped in a frequency first manner or a time first manner. However, it is further possible to define that the base station sets up the L1 control signaling (eg, DL assignment DCI or UL grant DCI) or UE-specific / cell-specific higher layer signaling for the frequency first manner or time first manner mapping.

2. TB-specific resource mapping

Resource mapping and rate matching for transmission resources constituting PDSCH or PUSCH allocated in TB units can be performed. That is, a consistent resource mapping and rate matching scheme can be applied to PDSCH / PUSCH resources allocated for the corresponding TB transmission irrespective of the number of CBs or CBGs constituting an arbitrary TB.

In addition, the CBG grouping method or the resource mapping / rate matching method of points 2 and 3 can be defined so that the base station sets CBG grouping method or resource mapping / rate matching method to be applied to each terminal. In this case, the corresponding CBG grouping method and the resource mapping / rate matching method may be independently set through separate information areas, or may be jointly set to one information area. Also, the setting can be semi-static set-up through UE-specific / cell-specific higher layer signaling, or dynamically set and transmitted through L1 control signaling (eg, DL assignment DCI or UL grant DCI).
