block (RB), a region, a band, a sub-band, a control chamiel, 

a data channel, a synchronization signal, various reference 

signals, various signals, and various messages associated 

with NR of the present disclosure may be interpreted as 

being used in the past or present or as various meanings to 40 

be used in the future. 

NR (New Radio) 

Recently, the 3GPP has approved the "Study on New 

Radio Access Technology", which is a study item for 

research on next-generation/5G radio access technology. On 45 

the basis of such a study item, the 3GPP have started 

discussions about frame structure, chamiel coding & modulation, waveform, multiple access scheme, etc. 

It is required to design the NR not only to provide a data 

transmission rate enhanced as compared with that of LTE/ 50 

LTE-Advanced, but also to meet various requirements for 

detailed and specific usage scenarios. In particular, an 

eMBB, mMTC, and URLLC have been discussed as representative usage scenarios of the NR, and it has been required 

to design more flexible frame structures as compared with 55 

those for LTE/LTE-Advanced in order to meet the requirements of each usage scenario. 

Specifically, the eMBB, mMTC, URLLC are considered 

as representative usage scenarios of the NR. Since each 

usage scenario imposes a different requirement of data rates, 60 

latency, coverage, etc., many discussions have conducted for 

a technique of efficiently multiplexing radio resource units 

based on different types of numerology (e.g., a subcarrier 

spacing (SCS), a subframe, a transmission time interval 

(TTI), etc.) in order to efficiently satisfy requirements 65 

according to usage scenarios through a frequency band of 

any NR system. 

6 

To this end, there also have been many discussions 

conducted for developing i) a technique of multiplexing 

numerology having different SCS values based on TDM, 

FDM or TDM/FDM through one NR carrier and ii) a 

technique of supporting one or more time units in configuring scheduling units in a time domain. 

In this regard, in the NR, a subframe has been defined as 

one type of time domain structure. As reference numerology 

to define a subframe duration, a single subframe duration is 

defined as having 14 OFDM symbols of 15 kHz SCS-based 

normal CP overhead, like the LTE. Therefore, the subframe 

in the NR may have a time duration of 1 ms. Unlike the LTE, 

since the subframe of the NR is an absolute reference time 

duration, a slot and a mini-slot may be defined as a time unit 

used for an actual UL/DL data scheduling. In this case, the 

number of OFDM symbols constituting a corresponding 

slot, a value ofy, has been defined as y=14 regardless of the 

numerology, but not limited thereto. 

Therefore, any slot may have 14 symbols. In accordance 

with a transmission direction for a slot, all of the symbols 

may be used for DL transmission or UL transmission, or the 

symbols may be used in the configuration of a DL portion+a 

gap+a UL portion. 

Further, a mini-slot having fewer symbols than the slot 

has been defined in any numerologies (or SCS), and, as a 

result, a short time domain scheduling interval for the 

transmission and reception of UL/DL data may be configured based on the mini-slot. Also, a long time domain 

scheduling interval for the transmission and reception of 

UL/DL data may be configured by slot aggregation. 

In particular, in case of transmission and reception of 

latency-critical data, such as Ultra-reliable low-latency communication (URLLC), when scheduling is performed on a 

slot basis according to 0.5 ms (7 symbols) or 1 ms (14 

symbols) defined in a frame structure based on a numerology having a small SCS value such as 15 kHz, it may be 

difficult to meet latency requirements. To solve this problem, 

a mini-slot having fewer OFDM symbols than the slot may 

be defined so that scheduling for latency-critical data, such 

as the URLLC, may be performed based on the mini-slot. 

Further, as described above, there has been discussions on 

a technique of scheduling data in accordance with latency 

requirements based on the length of the slot (or mini-slot) 

defined in each numerology, by multiplexing and supporting 

the numerologies using the TDM or FDM technique, which 

have different SCS values within one NR carrier. For 

example, as illustrated in FIG. 1, the length of a symbol for 

60 kHz SCS is shortened by a fourth of that for 15 kHz SCS, 

and thus a 60 kHz-based slot is shortened to have a length 

of about 0.125 ms as compared with a 15 kHz-based slot 

having a length of 0.5 ms under the same condition that 

seven OFDM symbols constitute one slot. 

As described above, techniques of satisfying each requirement ofURLLC and eMBB has been discussed by defining 

different SCSs or different TTI lengths in the NR. 

Wider Bandwidth Operations 

A typical LTE system supports a scalable bandwidth 

operation for an LTE component carrier (CC). An LTE 

service provider may use a bandwidth of at least 1.4 MHz up 

to 20 MHz according to a frequency deployment scenario 

when configuring one LTE CC. Accordingly, an LTE UE 

supports transmission/reception capabilities of 20 MHz 

bandwidth for one LTE CC. 

However, the NR has been designed to support UEs each 

having different transmission/reception bandwidth capability from another in one broadband NR component carrier. 

Accordingly, as illustrated in FIG. 2, it is required to

format for the transmission of UL control information with 

a payload size ofup to two bits and ii) a PUCCH format for 

the transmission of UL control information with a payload 

size exceeding 2 bits. Furthermore, for the long duration 

configure one or more bandwidth parts (BWPs) constituting 

bandwidths obtained by subdividing an NR CC and to 

support a wider and flexible bandwidth operation by configuring and activating different BWPs from each other to 

each UE. 

Specifically, in the NR, one or more BWPs may be 

configured through one serving cell from a view of a UE. 

The UE may transmit and/or receive UP/DL data by activating one DL BWP and one UP BWP, in the serving cell. 

Furthermore, in a case where the UE are connected to a 

plurality of serving cells ( e.g., when the UE performs carrier 

aggregation (CA)), the UE may transmit and/or receive 

UP/DL data by activating one DL BWP and/or one UL BWP 

5 PUCCH, the NR defines i) a PUCCH format for the transmission of UL control information with a payload size ofup 

to two bits and ii) a PUCCH format for the transmission of 

UL control information with a payload size exceeding 2 bits. 

As described, for defining a PUCCH structure to transmit 

10 UL control information in the NR, it may be required to 

define a PUCCH duration and a PUCCH format. 

In accordance with an embodiment of the present disclosure, a method may be provided for allocating a PUCCH 

for each serving cell and using a radio resource of each resource for HARQ ACK/NACK feedback or aperiodic CSI 

serving cell. 15 reporting by a UE in the NR. In some embodiments of the 

present disclosure, the PUCCH resource allocation method 

is described as being applied for HARQ ACK/NACK feedback and aperiodic CSI reporting by a UE, but it is not 

Specifically, an initial bandwidth part (BWP) may be 

defined for an initial access procedure in any serving cell, 

and one or more VE-specific BWPs may be configured 

through RRC signaling dedicated for each UE, and a default 

bandwidth part (BWP) may be defined for a fallback opera- 20 

tion for each UE. 

limited thereto. For example, the PUCCH resource allocation method according to embodiments may be applied for 

a service request (SR) or periodic CSI reporting. 

It is possible to define A plurality of downlink and/or 

uplink BWPs to be simultaneously activated and used 

according to the configurations of BWPs and the capability 

of a UE in any serving cell. However, the NR rel-15 defines 

that only one DL BWP and one UL BWP are activated and 

used in an UE at any time. 

As described above, in the NR, one or more BWPs may 

be configured through one serving cell from a UE perspective. For example, at least one DL BWP and at least one UL 

25 BWP may be configured according to a transmission direction supported by the serving cell that usesunpaired spectrum (i.e. TDD) or paired spectrum (i.e. FDD). 

NRPUCCH The NR defines a BS to activate and use only one DL 

In the typical LTE system, a PUCCH is transmitted on a BWP and one UL BWP at a predetermined time for each UE 

single subframe basis, where the PUCCH is an UL control 

channel for the transmission of uplink control information 

(UCI) by a UE. That is, one PUCCH is transmitted through 

30 in order for transmitting and receiving each of DL/UL radio 

channel and signal (e.g. PDCCH/PDSCH, PUSCH/PUCCH 

etc.) When the serving cell is a DL-only cell or an UL-only 

14 SC-FDMA symbols constituting one subframe in a time cell, the serving cell may activate and use only one or more 

domain. In a case where the last symbol is used for an SRS 

transmission, the PUCCH is transmitted through 13 symbols 35 

except for the last symbol. 

Furthermore, different PUCCH formats are defined 

according to payload sizes of UL control information. For 

example, the different PUCCH formats are defined as follows: i) PUCCH format 1/la/lb is used to transmit UL 40 

control information of one or two bits ( e.g., a scheduling 

request (SR) and a HARQ ACK); ii) PUCCH format 2a/2b 

is used to transmit an UL control information having a 

moderate payload size ( e.g., CQI/CSI feedback); and 

PUCCH format 3 or more is used to transmit the feedback 45 

of the UL control information having a large payload size 

when carrier aggregation (CA) is used. 

However, the NR defines a PUCCH structure to have 

various durations in a slot having 14 symbols. For example, 

the NR defines a long duration PUCCH and a short duration 50 

PUCCH according to the number of symbols required to 

transmit a single PUCCH, N values, in a single slot for the 

transmission of uplink control information (UCI) by a UE. 

DL BWPs or only one or more UL BWPs. 

Accordingly, in a UE perspective, one or more UL BWPs 

and/or DL BWPs may be independently provided and activated for a secondary cell (Scell) configured for carrier 

aggregation, in addition to a primary cell (Pcell) to which the 

UE is connected first. 

As described, when one or more BWPs are configured in 

an serving cell of an UE, the UE can activate and use one 

BWP at any time. 

Specifically, for a DL transmission and/or reception, the 

serving cell activates and uses one DL BWP in any DL 

subframe/slot/mini-slot of one or more DL BWPs configured for a corresponding UE. Likewise, for an UL transmission and/or reception, the serving cell activates and uses 

one UL BWP in any UL subframe/slot/mini-slot of one or 

more UL BWPs configured for the UE. 

Activation/deactivation indications of the DL BWP and 

the UL BWP to an UE may be performed through DL control 

information (DCI) transmitted through a PDCCH. For 

example, the activation/deactivation of the DL BWP may be 

For the UE to transmit the UCI, the NR defines two types of performed through DL assignment DL control information

Hereinafter, the short and long duration PUCCHs may be 

refer to as short and long PUCCHs respectively. That is, the 

short duration PUCCH may be transmitted using one or two 60 

symbols, and the long duration PUCCH may be transmitted 

using four to fourteen symbols in one symbol. 

Furthermore, similar to the typical LTE, the NR defines 

different PUCCH formats according to payload sizes of 

uplink control information for each of the long duration 65 

PUCCH and the short duration PUCCH. For example, for 

the short duration PUCCH, the NR defines i) a PUCCH 

Furthermore, the activation/deactivation of the UL BWP 

may be performed through an UL grant containing resource 

allocation information on a PUSCH. 

For example, a UE may receive, from a BS, BWP 

configuration information on one or more BWP sets constituted by one or more BWPs configured for the UE. Next, the 

UE may receive, from the BS, DL control information 

containing information that indicates one of one or more 

BWPs contained in the one or more BWP sets configured by 

the BWP configuration information. The UE may receive the 

PDSCH or transmit the PUSCH or PUCCH through the one 

BWP indicated in the DL control information.

At this time, the BWP configuration information may be

trated in FIG. 3B, the BWP #2 including one or multiple 

PUCCH resource sets may be formed of a first to fourth 

PUCCH resource sets. 

In accordance with an embodiment of the present disclosure, provided are a PUCCH resource allocation method 5 

considering a VE-specific BWP based operation and 

detailed operations of a UE and a BE related thereto. In 

particular, in connection with the activation/deactivation of 

As described, each PUCCH resource includes one or 

multiple PUCCH resource sets configured for each UL BWP 

through higher layer signaling. Such each PUCCH resource 

may be defined as PUCCH format configuration information, time/frequency domain PUCCH resource configuration 

information ( or additionally code domain resource configu- the UL BWP, provided is a specific method of allocating a 

PUCCH resource to prevent ambiguity between indication 10 

and interpretation of a PUCCH transceiving resource of a 

ration information) in the UL BWP, or the like. For example, 

as illustrated in FIG. 3B, a specific PUCCH resource set, 

such as a second PUCCH resource set, may be configured by 

a first to fourth PUCCH resources. BS and a UE, resulted from UL BWP switching. 

In the NR, a BS/network may configure a single PUCCH 

resource set configured by one or more PUCCH resources 15 

for HARQ ACK/NACK feedback or a plurality of PUCCH 

resource sets, each of which is configured by one or more 

PUCCH resources, for each UE, and then transmit the 

configured one or more PUCCH resource sets to each UE 

through VE-specific higher layer signaling. 20 

As described above, when one or multiple PUCCH 

resource sets configure each BWP through the higher layer 

signaling, in configuring an area of PUCCH resource indication information through the DL allocation DL control 

information, the BS may include explicitly UL BWP indication information for the transmission of a PUCCH therein. 

For example, the PUCCH resource indication information 

through the DL allocation DL control information may 

include UL BWP indication information (e.g. BWP index 

information)+PUCCH resource set indication information 

( e.g. PUCCH resource set index information) in the corresponding UL BWP+PUCCH resource indication information ( e.g. a PUCCH resource index in the PUCCH resource 

As described, when one or multiple PUCCH resource sets 

are configured for an UE through the VE-specific higher 

layer signaling, the BS may include PUCCH resource indication information as HARQ ACK/NACK feedback in 

response to a PDSCH reception at a corresponding UE in DL 25 

allocation DL control information and transmit the DL 

allocation DL control information containing the PUCCH 

resource indication information when transmitting PDSCH 

scheduling control information for the UE through a 

PDCCH. 

That is, for each PDSCH transmission for an UE, the BS 

selects i) one of i) PUCCH resources configuring a single 

PUCCH resource set configured for the UE or ii) one of 

PUCCH resources configuring one of multiple PUCCH 

resource sets and a PUCCH resource set. Then, the BS 

transmits the selected one PUCCH resource through DL 

allocation DL control information. Accordingly, the UE may 

be defined to dynamically allocate a PUCCH resource to be 

used for HARQ ACK/NACK feedback. 

30 

set) to be used by the UE for HARQ ACK/NACK feedback 

of PUCCH resources configuring the corresponding 

PUCCH resource set. 

In this regard, when a BWP is configured with specific 

classes of PUCCH resource sets, the PUCCH resource set 

indication information may be replaced by the specific 

classification information. For example, when a separate 

PUCCH resource set is configured for each of a PUCCH 

35 format, the PUCCH resource set indication information may 

include a PUCCH duration, a PUCCH payload size, and the 

like, each of the corresponding PUCCH format information, 

PUCCH duration information, PUCCH payload size information, and the like. 

In accordance with an embodiment of the present disclo- 40 

sure, proposed are a method of configuring a PUCCH 

resource set and a method of indicating the corresponding 

PUCCH resource. 

For example, as described above, when a PUCCH 

resource set is configured through RRC signaling, a separate 

PUCCH resource set for each PUCCH format may be 

configured, and the PUCCH format indication information 

As a method of configuring one or more PUCCH resource for the HARQ ACK/NACK feedback of the UE may be 

sets for an UE, in configuring one or more PUCCH resource 

sets for each UE for HARQ ACK/NACK feedback of the 

UE, it may be defined that one or more separate resource sets 

are configured for each UL BWP configured for the UE. 

For example, as illustrated in FIG. 3A, when N (e.g, N is 

a natural number greater than 1) UL BWPs for any UE are 

configured, it may be defined that separate one or multiple 

PUCCH resource sets are configured for each UL BWP to 

indicate a PUCCH resource for HARQ ACK/NACK feedback of the UE and then transmitted to the UE through 

VE-specific higher layer signaling. Although FIG. 3A shows 

that overlapping between the BWPs in each frequency axis 

does not occur, one or more BWPs may be configured to 

overlap with another BWP partially or fully in any frequency 

axis. However, the present embodiment is not limited to a 

specific UL BWP configuration. 

Referring to FIG. 3B, the BS may configure total N 

groups of one or multiple PUCCH resource sets per each 

BWP for a UE, for example, from one or multiple PUCCH 

resource sets for a BWP #1, one or multiple PUCCH 

resource sets for a BWP #2, . . . , up to one or multiple 

PUCCH resource sets for a BWP #N, where N is an integer 

number equal to and greater than 1. For example, as illus45 transmitted through the DL allocation DL control information, and thus a resource set for PUCCH resource allocation 

of the UE may be derived. 

For another example, a separate PUCCH resource set may 

be configured according to a PUCCH payload size to be 

50 transmitted by the UE, i.e. the payload size of UL control 

information, and the PUCCH resource set for the PUCCH 

resource allocation may be determined according to the UL 

control information payload size to be transmitted by the 

UE. As illustrated in FIG. 3B, only the PUCCH resource 

55 indication information (e.g. an ACK/NACK resource indication (ARI)) may be transmitted through DL allocation DL 

control information, and, when the UE determines one or 

more PUCCH resource sets to interpret it, derived may be a 

corresponding PUCCH resource set according to an UL 

60 control information payload size (UCI payload size) to be 

transmitted by the UE through a PUCCH resource allocated 

through the corresponding DL allocation DL control. 

For example, the UL control information payload size 

may be divided into four areas according to the number of 

65 bits, and one of a first to fourth PUCCH resource sets may 

be derived according to the number of bits of the UL control 

information, as illustrated in FIG. 3B. 

Case 2:23-cv-00639-JRG Document 1-8 Filed 12/29/23 Page 17 of 23 PageID #: 258
US 10,638,463 B2 

11 

As illustrated in FIG. 3C, DL allocation DL control 

information may contain PUCCH resource indication information (PUCCH resource information or a PUCCH resource 

indicator). The PUCCH resource indication information 

indicates one UL control channel resource, for the transmis- 5 

sion of UL control information, of UL control channel 

resources configuring an UL control channel resource set. 

For example, as illustrated in FIG. 3B, in a case where the 

UL control channel resource set is formed of the first to 

fourth PUCCH resources, PUCCH resource indication infor- 10 

mation illustrated in FIG. 3C may indicate one of the four 

PUCCH resources. 

12 

above, an UL BWP for the PUCCH transmission may be 

determined as an active UL BWP of the corresponding UE 

in a slot for the transmission of the DL allocation DL control 

information. 

As another method of implicitly determining an UL BWP, 

an UL BWP for the transmission of the PUCCH may be 

determined as an active UL BWP in a time point to transmit 

the PUCCH of the corresponding UE, that is, a slot through 

which the PUCCH is transmitted ( or in a case where the 

PUCCH is transmitted through a plurality of slots, a slot 

through which the transmission of the PUCCH is started.) As 

another method of implicitly determining an UL BWP for 

the PUCCH transmission, UL BWPs associated with each 

other for the PUCCH transmission for each DL BWP to 

The PUCCH resource set information (or including indication information according to the classification of the 

PUCCH) and the PUCCH resource index information in the 

corresponding PUCCH resource set may be encoded in a 

joint coding scheme and transmitted or received through one 

information area. The information related to the PUCCH 

resource set indication may be required only in a case that 

supports to configure a plurality of PUCCH resource sets in 

one UL BWP, and when the configuration of only one 

UCCH resource set per one UL BWP is supported, the 

PUCCH resource set indication information may be 

excluded. 

15 which DL allocation DL control information for PDSCH 

resource allocation may be transmitted. 

Also, the UL BWPs associated with each other for the 

PUCCH transmission for each DL BWP through which 

PDSCH transmission may be performed according to DL 

20 allocation DL control information. In this case, the BS may 

configure UL BWPs associated with each other for the 

PUCCH transmission for each DL BWP configured for an 

UE and transmit them to the corresponding UE through a 

As described, when the UL BWP indication information 25 

for the transmission of the PUCCH is included in the DL 

VE-specific high layer signaling or Ll control signaling, or 

define implicitly a DL BWP-UL BWP association rule. 

For example, in a case where the same BWP configuration 

is performed for both a DL and an UL in a TDD cell, or in 

a case where the same number of BWP configurations is 

performed for both a DL and an UL in a TDD/FDD cell, the 

allocation DL control information, the UL BWP indication 

information may be additionally used as UL BWP activation 

information of the UE and UL BWP switching indication 

information resulted therefrom. 

For example, the UE may perform UL BWP switching, 

according to the UL BWP indication information, after a 

predetermined slot, for example, k slots, from a slot to 

receive the UE the DL allocation DL control information. In 

this case, the UL BWP switching means an operation of 

deactivating a currently-active UL BWP and activating a 

new UL BWP according to the indication information. 

30 DL BWP and the UL BWP of the same index may be 

associated with each other. 

As another method of configuring one or more PUCCH 

resource sets for HARQ ACK/NACK feedback of the UE, 

the one or more PUCCH resource sets may be commonly 

Furthermore, the UE may perform the UL BWP switching 

(that is, an operation of deactivating a currently-active UL 

BWP and activating a new UL BWP according to the 

indication information) according to UL BWP indication 

information before a predetermined slot, for example, j slots, 

from a PUCCH transmission slot. In this case, the k value or 

35 configured to one or more UL BWP. That is, when PUCCH 

resources configuring one PUCCH resource set configured 

for a UE is defined, each of the PUCCH resources configuring the PUCCH resource set may be configured with one 

or more PUCCH resources defined in all UL BWPs config40 ured for the UE. 

the j value is an arbitrary integer value of O or more and has 

a certain fixed value. The k value or the j value may be 45 

configured by a BS and transmitted through higher layer 

signaling, or the k value or the j value may be determined 

according to the capability of the UE. When the UL BWP 

indication information indicates a currently-active UL BWP, 

the UE does not perform the operation of the UL BWP 50 

switching. 

As another method of configuring a PUCCH resource 

indication information area through DL allocation DL control information, the UL BWP may be determined implicitly. 

As a result, the PUCCH resource indication information of 55 

the DL allocation DL control information may be configured 

by a PUCCH resource set indication information+PUCCH 

resource indication information, to be used for HARQ 

ACK/NACK feedback by the UE, of PUCCH resources 

configuring the PUCCH resource set, except for the UL 60 

BWP indication information. 

When a BS configures each of one or more PUCCH 

resources configuring one or more PUCCH resource sets for 

an UE, information on an UL BWP configured by the one or 

more PUCCH resources may be contained in each PUCCH 

resource. 

Accordingly, each PUCCH resource configuring one or 

multiple PUCCH resource sets configured through the 

higher layer signaling for an UE may be defined as PUCCH 

format configuration information, UL BWP configuration 

information, and time/frequency domain PUCCH resource 

configuration information in the UL BWP (or additionally 

code-domain resource configuration information), or the 

like. 

In this case, PUCCH resource indication information 

transmitted through the DL allocation DL control information, as in the case of the implicit UL BWP indication, may 

be configured by PUCCH resource set indication information (for example, PUCCH resource set index information)+ 

PUCCH resource indication information to be used for 

HARQ ACK/NACK feedback by the UE among PUCCH 

resources configuring the PUCCH resource set (for example, 

a PUCCH resource index in a PUCCH resource set), or only 

PUCCH resource indication information to be used for 

HARQ ACK/NACK feedback by the UE among PUCCH 

The PUCCH resource set indication information+the 

PUCCH resource indication information, to be used for 

HARQ ACK/NACK feedback by the UE, of PUCCH 

resources configuring the PUCCH resource set may be 

configured in the same manner as described above. In a case 

where the UL BWP is determined implicitly as described 

65 resources configuring one or more PUCCH resource sets 

(for example, a PUCCH resource index in a PUCCH 

resource set.) 

Case 2:23-cv-00639-JRG Document 1-8 Filed 12/29/23 Page 18 of 23 PageID #: 259

13 

Likewise, when a BWP is configured with specific classes 

of PUCCH resource sets, the PUCCH resource set indication 

information may be replaced by the specific classification 

information. 

For example, when a separate PUCCH resource set is 5 

configured for each of a PUCCH format, a PUCCH duration, 

a PUCCH payload size, and the like, each of the corresponding PUCCH format information, PUCCH duration information, PUCCH payload size information, and the like may be 

used in place of each of the PUCCH resource set indication 10 

information. 

The PUCCH resource set information (or, including indication information according to the classification of the 

PUCCH) and the PUCCH resource index information in the 15 

corresponding PUCCH resource set may be encoded in a 

joint coding scheme and transmitted or received through one 

information area. The information related to the PUCCH 

resource set indication may be necessary only in a case of 

supporting the configuration of a plurality of PUCCH 20 

resource sets for each UE. The PUCCH resource set indication information may be excluded in a case of supporting 

the configuration of only one UCCH resource for each UE. 

14 same mamier as the PUCCH resource set configuration 

method for the HARQ ACK/NACK feedback, or be configured regardless of that. 

When one or more separate PUCCH resource sets for 

aperiodic CSI reporting are configured, as described above, 

one or more PUCCH resource sets for the aperiodic CSI 

reporting may be configured for each UL BWP, or one or 

more PUCCH resource sets for the aperiodic CSI reporting 

may be commonly configured in one or more UL BWPs. 

In this regard, in a case where one or more PUCCH 

resource sets for separate aperiodic CSI reporting are configured, the PUCCH resource allocation for the HARQ 

ACK/NACK feedback through the DL allocation DL control 

information described above may be applied to PUCCH 

resource allocation for the aperiodic CSI reporting. Additionally, an operation described above may be applied to an 

UL B WP activation or a UE operation related to an UL B WP 

switching. 

Additionally, when aperiodic CSI reporting through an 

UL grant is triggered, radio chamiel indication information 

(i.e., a PUSCH or PUCCH) for the transmission of aperiodic 

CSI reporting information by a UE may be included. 

As described above, the method of the PUCCH resource 

set configuration and the method of the corresponding 

25 PUCCH resource indication have been discussed, referring 

to FIGS. 2 to 3C. Hereinafter, referring to FIGS. 4 to 7, 

methods of transmitting and receiving UL control information by a UE and/or a BS, and the related UE and BS will 

be described in detail. 

Additionally, when configuration information on PUCCH 

resources configuring PUCCH resource sets configured 

through high layer signaling contains UL BWP configuration information, according to PUCCH resource allocation 

indicated by PUCCH resource indication information ofDL 

allocation DL control information, as in the case of the 

explicit UL BWP indication, the UE may perform an UL 30 

BWP activation or an UL BWP switching operation to an UL 

BWP configured by the one or more PUCCH resources. 

Additionally, as described above, when PUCCH resource 

sets for HARQ ACK/NACK feedback of the UE for each UL 

BWP are configured, or when one or more PUCCH resource 35 

sets are commonly configured in one or more UL BWPs, 

each PUCCH resource configuring the one or more PUCCH 

resource sets may be allocated for aperiodic CSI feedback of 

the UE. 

FIG. 4 is a flowchart showing a method of a UE for 

transmitting UL control information b according to embodiments of the present disclosure. 

Referring to FIG. 4, a UE receives, from a BS, UL control 

channel resource set configuration information for transmitting the UL control information S400. 

One or more UL control chamiel resource sets may be 

configured for each UL BWP configured for a UE. The UL 

BWP may be activated through DL control information. 

Specifically, a corresponding serving cell for a DL transSpecifically, aperiodic CSI reporting of any UE may be 

triggered by the BS through DL allocation DL control 

information. For this purpose, when a DL allocation DL 

control information format for an UE is defined, an information area for triggering aperiodic CSI reporting of the UE 

may be defined to be included therein. In a case where the 

aperiodic CSI reporting of the UE is triggered through the 

aperiodic CSI reporting indication information area, the 

aperiodic CSI reporting information may be multiplexed and 

then transmitted, along with HARQ ACK/NACK feedback 

information on a PDSCH through the one or more PUCCH 

resources according to the PUCCH resource allocation 

information indicated through the DL allocation DL control 

information. That is, the PUCCH resource set configuration 

may be a common PUCCH resource set configuration for 

HARQ ACK/NACK feedback and aperiodic CSI reporting.

corresponding serving cell for an UL transmission and/or 

reception activates and uses one UL BWP contained in an 

45 UL subframe/slot/mini-slot of one or more UL BWPs configured for a corresponding UE. 

Activation/deactivation indications of the DL BWP and 

the UL BWP to an UE may be performed through DL control 

information (DCI) transmitted through a PDCCH. Specifi50 cally, the activation/deactivation of the DL BWP may be 

performed through DL assignnient DL control information 

containing resource allocation information on a PDSCH. 

Furthermore, the activation/deactivation of the UL BWP 

may be performed through an UL grant including resource 

55 allocation information on a PUSCH. 

In addition, apart from the configuration of one or more 

PUCCH resource sets for the HARQ ACK/NACK feedback, 

a BE/network may configure one or more PUCCH resource 

sets for aperiodic CSI reporting and transmit the configured 

one or more PUCCH resource sets to each UE through 60 

VE-specific High layer signaling. That is, one or multiple 

PUCCH resource sets for only aperiodic CSI feedback for 

each UE may be configured and transmitted to each UE 

through VE-specific High layer signaling. 

In this case, one or more PUCCH resource sets for the 65 

aperiodic CSI feedback may be separately configured for 

each PUCCH format or for each PUCCH duration, in the 

For example, a UE may receive BWP configuration 

information on one or more BWP sets configured by one or 

more BWPs configured for the UE from a BS. Next, the UE 

may receive, from the BS, DL control information containing information for indicating one of one or more BWPs 

contained in the one or more BWP sets configured by the 

BWP configuration information. The UE may receive the 

PDSCH or transmit the PUSCH or PUCCH through the one 

BWP indicated in the DL control information. 

At this time, the BWP configuration information may be

In the NR, a BS/network may configure a single PUCCH 

resource set configured by one or more PUCCH resources 

for HARQ ACK/NACK feedback or a plurality of PUCCH 

resource sets, each of which is configured by one or more 

PUCCH resources, for each UE, and then transmit the 

configured one or more PUCCH resource sets to each UE 

through VE-specific higher layer signaling. 

In a case where one or multiple PUCCH resource sets for 

an UE through the VE-specific higher layer signaling are 

configured, the BS may transmit corresponding DL alloca- 10 

tion DL control information including PUCCH resource 

indication information for HARQ ACK/NACK feedback by 

the UE in response to a corresponding PDSCH reception 

when transmitting PDSCH scheduling control information 15 

for the UE through a PDCCH. 

Furthermore, the UE determines one of UL control channel resource sets contained in UL control channel resource 

set configuration information S410. 

In step S410, when the UL control channel resource sets 20 

to transmit the UL control information are determined, the 

UE may determine one of the UL control channel resource 

sets according to the size of the UL control information. 

Furthermore, the UE determines one of UL control channel resources contained in the determined one UL control 25 

channel resource set S420. 

Additionally, the UE may receive from the BS DL control 

information containing information indicating one, for the 

transmission of the UL control information, of UL control 

channel resources configuring UL control channel resource 30 

sets. 

At this time, the one UL control channel resource for the 

UL control information transmission of the UL control 

channel resources contained in the determined UL control 

channel resource set may be indicated from the BS through 35 

the DL control information. 

16 or the like. For example, as illustrated in FIG. 3B, a second 

PUCCH resource set may be configured by a first to fourth 

PUCCH resources. 

Furthermore, when a BWP is configured with specific 

classes of PUCCH resource sets, the PUCCH resource set 

indication information may be replaced by the specific 

classification information. For example when a separate 

PUCCH resource set is configured for each of a PUCCH 

format, a PUCCH duration, a PUCCH payload size, and the 

like, each of the corresponding PUCCH format information, 

PUCCH duration information, PUCCH payload size information, and the like may be used in place of each of the 

PUCCH resource set indication information. 

That is, a separate PUCCH resource set may be configured according to a PUCCH payload size to be transmitted 

by the UE, i.e. the payload size of UL control information, 

and the PUCCH resource set for the PUCCH resource 

allocation may be determined according to the UL control 

information payload size to be transmitted by the UE. As 

illustrated in FIG. 3B, only the PUCCH resource indication 

information ( e.g. an ACK/NACK resource indication (ARI) 

may be transmitted through DL allocation DL control information, and, when the UE determines one or more PUCCH 

resource sets to interpret it, derived may be a corresponding 

PUCCH resource set according to an UL control information 

payload size (UCI payload size) to be transmitted by the UE 

through a PUCCH resource allocated through the corresponding DL allocation DL control. 

For example, the UL control information payload size 

may be divided into four areas according to the number of 

bits, and one of a first to fourth PUCCH resource sets may 

be derived according to the number of bits of the UL control 

information, as illustrated in FIG. 3B. 

As illustrated in FIG. 3C, DL allocation DL control 

information may contain PUCCH resource indication information (PUCCH resource information or a PUCCH resource 

indicator). The PUCCH resource indication information 

indicates one UL control channel resource, for the transmission of UL control information, of UL control channel 

As described above, the UE may determine, for each 

PDSCH transmission, one of PUCCH resources contained in 

a single PUCCH resource set configured for the UE, or 

determine one of a plurality of PUCCH resource sets configured for the UE and one of PUCCH resources contained 

in the corresponding PUCCH resource set, and then dynamically allocate a PUCCH resource. 

40 resources configuring an UL control channel resource set. 

For example, as illustrated in FIG. 3B, in a case where the 

UL control channel resource set is configured by the first to 

fourth PUCCH resources, PUCCH resource indication inforSpecifically, as a method of configuring PUCCH resource mation illustrated in FIG. 3C may indicate one of the four 

sets for an UE, in configuring PUCCH resource sets for each 

UE for HARQ ACK/NACK feedback of the UE, separate 

resource sets may be configured for each UL BWP configured for the UE. 

45 PUCCH resources. 

For example, as illustrated in FIG. 3A, in a case where N 

(N is a natural number greater than 1) UL BWPs for an UE 50 

are configured, separate PUCCH resource sets to each UL 

BWP for a PUCCH resource indication for HARQ ACK/ 

NACK feedback of the UE may be configured and transmitted to the UE through VE-specific higher layer signaling. 

Referring to FIG. 3B, the BS may configure, for each 55 

BWP for a UE, total N PUCCH resource sets, for example, 

from PUCCH resource sets for a BWP #1, PUCCH resource 

sets for a BWP #2, ... , up to PUCCH resource sets for a 

BWP #N. For example, as illustrated in FIG. 3B, the BWP 

#2 including PUCCH resource sets may be configured by a 60 

first to fourth PUCCH resource sets. 

The various methods described above referring to FIGS. 

2 to 3C may be applied to a specific PUCCH resource set 

configuration method and a corresponding PUCCH resource 

indication in some embodiments of the present disclosure. 

The UE transmits the UL control information through the 

determined the UL control channel resource S430. 

FIG. 5 is a flowchart of a BS for receiving UL control 

information according to some embodiments of the present 

disclosure. 

Referring to FIG. 5, a BS transmits to a UE UL control 

channel resource set configuration information for the transmission of the UL control information SS00. 

As described above, one or more UL control channel 

resource sets may be configured for each UL BWP configured for a UE. The UL BWP may be activated through DL 

control information. 

In this case, each PUCCH resource configuring PUCCH 

resource sets configured for each UL BWP through higher 

layer signaling may be defined as PUCCH format configuration information, time/frequency domain PUCCH 

resource configuration information ( or additionally code 

domain resource configuration information) in the UL BWP, 

Specifically, a corresponding serving cell for a DL transmission and/or reception activates to use one DL BWP 

contained in any DL subframe/slot/mini-slot of one or more 

65 DL BWPs configured for a corresponding UE. Likewise, the 

corresponding serving cell for an UL transmission and/or 

reception activates to use one UL BWP contained in any UL

subframe/slot/mini-slot of one or more UL BWPs configured for the corresponding UE. 

Activation/deactivation indications of the DL BWP and 

18 

the UL BWP to an UE may be performed through DL control 

information (DCI) transmitted through a PDCCH. Specifi- 5 

cally, the activation/deactivation of the DL BWP may be 

performed through DL assignment DL control information 

containing resource allocation information on a PDSCH. 

Furthermore, the activation/deactivation of the UL BWP 

may be performed through an UL grant containing resource 10 

allocation information on a PUSCH. 

As a method of configuring one or more PUCCH resource 

sets for an UE, in configuring PUCCH resource sets for each 

UE for HARQ ACK/NACK feedback of the UE, one or 

more separate resource sets may be configured for each UL 

BWP configured for the UE. 

For example, as illustrated in FIG. 3A, in a case where N 

(N is a natural number greater than 1) UL BWPs for an UE 

are configured, separate PUCCH resource sets to each UL 

BWP for a PUCCH resource indication for HARQ ACK/ 

NACK feedback of the UE may be configured and transmitted to the UE through VE-specific higher layer signaling. 

For example, the UE may receive BWP configuration 

information on BWP sets configured by BWPs configured 

for the UE from the BS. Next, the UE may receive DL 

control information containing information indicating one of 

BWPs contained in the BWP sets configured by the BWP 

configuration information from the BS. The UE may receive 

the PDSCH, or transmit the PUSCH or PUCCH through the 

one BWP indicated in the DL control information. 

At this time, the BWP configuration information may be 

receive from the BS through high layer signaling, such as 

RRC signaling. 

In the NR, a BS/network may configure a single PUCCH 

resource set configured by PUCCH resources for HARQ 

ACK/NACK feedback or a plurality of PUCCH resource 

sets, each of which is configured by PUCCH resources, for 

each UE, and then transmit the configured PUCCH resource 

sets to each UE through VE-specific higher layer signaling. 

Referring to FIG. 3B, the BS may set, for each BWP for 

a UE, total N PUCCH resource sets, for example, from 

15 PUCCH resource sets for a BWP #1, PUCCH resource sets 

for a BWP #2, ... , up to one or multiple PUCCH resource 

sets for a BWP #N. For example, as illustrated in FIG. 3B, 

the BWP #2 including PUCCH resource sets, may be 

configured by a first to fourth PUCCH resource sets. 

20 In this case, each PUCCH resource configuring PUCCH 

resource sets configured for each UL BWP through higher 

layer signaling may be defined as PUCCH format configuration information, time/frequency domain PUCCH 

resource configuration information ( or additionally code 

25 domain resource configuration information) in the UL BWP, 

or the like. For example, as illustrated in FIG. 3B, a second 

PUCCH resource set may be configured by a first to fourth 

PUCCH resources. 

In a case where PUCCH resource sets for an UE through the 30 

VE-specific higher layer signaling are configured, when 

transmitting PDSCH scheduling control information for the 

In this regard, when a BWP is configured with specific 

classes of PUCCH resource sets, the PUCCH resource set 

indication information may be replaced by the specific 

classification information. For example, when a separate 

PUCCH resource set is configured to each of a PUCCH 

format, a PUCCH duration, a PUCCH payload size, and the 

UE through a PDCCH, the BS may transmit corresponding 

DL allocation DL control information including PUCCH 

resource indication information for HARQ ACK/NACK 35 

feedback by the UE in response to a corresponding PDSCH 

like, each of the corresponding PUCCH format information, 

PUCCH duration information, PUCCH payload size inforreception. 

Furthermore, the BS receives UL control information 

through one of UL control channel resources configuring 

one of UL control channel resources contained in UL control 40 

mation, and the like may be used in place of each of the 

PUCCH resource set indication information. 

That is, a separate PUCCH resource set may be configured according to a PUCCH payload size to be transmitted 

by the UE, i.e. the payload size of UL control information, 

and the PUCCH resource set for the PUCCH resource 

allocation may be determined according to the UL control 

information payload size to be transmitted by the UE. As 

channel resource set configuration information S510. 

As described above, the UL control channel resource sets 

for transmitting the UL control information may be determined as one of the UL control channel resource sets 

according to the size of the UL control information. 

As described above, the BS may transmit to the UE DL 

control information containing information indicating one, 

for the transmission of the UL control information, of UL 

control channel resources configuring UL control channel 

resource sets. 

At this time, for the UL control information transmission, 

the one of the UL control channel resources configuring the 

UL control channel resource sets may be indicated to the UE 

through the DL control information. 

That is, the BS selects, for each PDSCH transmission for 

an UE, one of PUCCH resources configuring a single 

PUCCH resource set configured for the UE, or one of 

PUCCH resources configuring one of PUCCH resource sets 

and a PUCCH resource set, configured for the UE. Then, the 

BS transmits the selected PUCCH resource through DL 

allocation DL control information. Accordingly, the UE 

dynamically may allocate a PUCCH resource to be used for 

HARQ ACK/NACK feedback. 

In accordance with an embodiment of the present disclosure, proposed are a method of configuring a PUCCH 

resource set and a method of indicating the corresponding 

PUCCH resource. 

45 illustrated in FIG. 3B, only the PUCCH resource indication 

information ( e.g. an ACK/NACK resource indication (ARI) 

may be transmitted through DL allocation DL control information, and, when the UE determines one or more PUCCH 

resource sets to interpret it, derived may be a corresponding 

50 PUCCH resource set according to an UL control information 

payload size (UCI payload size) to be transmitted by the UE 

through a PUCCH resource allocated through the corresponding DL allocation DL control. 

For example, the UL control information payload size 

55 may be divided into four areas according to the number of 

bits, and one of a first to fourth PUCCH resource sets may 

be derived according to the number of bits of the UL control 

information, as illustrated in FIG. 3B. 

As illustrated in FIG. 3C, DL allocation DL control 

60 information may contain PUCCH resource indication information (PUCCH resource information or a PUCCH resource 

indicator). The PUCCH resource indication information 

indicates one UL control channel resource, for the transmission of UL control information, of UL control channel 

65 resources configuring an UL control channel resource set. 

For example, as illustrated in FIG. 3B, in a case where the
