Description

Method and device for repetitive transmission and frequency hopping of uplink control channel in communication system The present disclosure relates to an uplink control channel transmission technique in a communication system, and more particularly, to a frequency hopping technique and repetitive transmission of an implicit indication-based uplink control channel for improving coverage of a terminal in a non-terrestrial network. Communication networks (e.g., 5G communication networks, 6G communication networks, etc.) are being developed to provide improved communication services compared to existing communication networks (e.g., long term evolution (LTE), advanced LTE-A (LTE-A), etc.). 5G communication networks (e.g., new radio (NR) communication networks) can support frequency bands above 6 GHz as well as frequency bands below 6 GHz. In other words, 5G communication networks can support FR1 bands and / or FR2 bands. 5G communication networks can support various communication services and scenarios compared to LTE communication networks. For example, usage scenarios of 5G communication networks can include enhanced Mobile Broadband (eMBB), Ultra Reliable Low Latency Communication (URLLC), massive Machine Type Communication (mMTC), etc. Compared to 5G, 6G communication networks can support a wider range of communication services and scenarios. 6G communication networks can meet requirements for ultra-high performance, ultra-high bandwidth, ultra-high space, ultra-high precision, ultra-intelligence, and / or ultra-reliability. 6G communication networks can support diverse and wide frequency bands and be applied to various usage scenarios (e.g., terrestrial communications, non-terrestrial communications, sidelink communications, etc.). Communication networks (e.g., 5G communication networks, 6G communication networks, etc.) can provide communication services to terminals located on the ground. Demand for communication services for not only terrestrial but also non-terrestrial devices such as aircraft, drones, and satellites is increasing, and technologies for non-terrestrial networks (NTNs) are being discussed to address this need. Non-terrestrial networks can be implemented based on 5G communication technologies, 6G communication technologies, etc. In non-terrestrial networks, communication between satellites and ground-based communication nodes, or between non-terrestrial communication nodes (e.g., aircraft, drones, etc.) can be performed based on 5G communication technologies, 6G communication technologies, etc. In non-terrestrial networks, the physical distance between a terminal and a base station may be longer than that between a terminal and a base station in a terrestrial network. In non-terrestrial networks, path loss may be high, and delays may be long. In non-terrestrial networks, the transmit power constraints for uplink communication at a transmitter (e.g., a terminal) may be greater than the transmit power constraints for downlink communication at a transmitter (e.g., a base station). Due to the long delays, real-time exchange of control messages (e.g., control information) between a base station and a terminal may be challenging. The purpose of the present disclosure to solve the above problems is to provide a method and device for repetitive transmission and frequency hopping of an uplink control channel in a communication system. A method of a UE (user equipment) according to embodiments of the present disclosure for achieving the above object may include: receiving PUCCH configuration information for repeated transmission and frequency hopping of a physical uplink control channel (PUCCH) from a base station; obtaining UE-specific information from the base station in a random access (RA) procedure; receiving a physical downlink shared channel (PDSCH) from the base station in the RA procedure; and transmitting a PUCCH including HARQ-ACK (hybrid automatic repeat request acknowledgment) feedback information of the PDSCH to the base station based on the PUCCH configuration information and the UE-specific information. The above PUCCH is a common PUCCH including one or more PUCCH transmissions, and a frequency resource for transmitting each of the one or more PUCCH transmissions to the base station can be determined using at least one of PUCCH symbol information included in a slot, PUCCH start symbol position information within a slot, repetition factor information, hopping sequence start offset information, or hopping sequence information.

The step of generating the basic sequence based on the UE-specific information includes the steps of: selecting basic sequence generation information used to generate the basic sequence from among the UE-specific information; converting the basic sequence into a Q-base sequence; performing compensation on the Q-base sequence; and performing combination on the result of performing the compensation, wherein Q may be a natural number of 2 or more.

The step of transmitting each of the one or more PUCCH transmissions to the base station includes the step of determining a frequency resource of each of the one or more PUCCH transmissions, and in determining the frequency resource of each of the one or more PUCCH transmissions, for the hopping sequence, one of a predefined starting offset, a starting offset that changes over time, or a starting offset corresponding to the last element value of a previous hopping sequence may be applied as the starting offset. The step of transmitting the PUCCH to the base station based on the PUCCH configuration information and the UE specific information further includes the step of applying at least one of an interleaver or a scrambler, wherein at least one of the interleaver or the scrambler can be applied to at least one of the base sequence, the pre-hopping sequence or the hopping sequence. The above RA procedure is a 4-step RA procedure, and the UE-specific information may be included in at least one of message 1 of the RA procedure, message 2 of the RA procedure, message 3 of the RA procedure, or message 4 of the RA procedure. The above RA procedure is a 2-step RA procedure, and the UE-specific information may be included in at least one of message A of the RA procedure or message B of the RA procedure. The above PUCCH configuration information is received from the base station via a cell-specific message, and the cell-specific message may be at least one of a system information block (SIB)1 or SIB19. The step of obtaining the UE-specific information from the base station includes the step of transmitting a request for the UE-specific information to the base station; and the step of receiving the UE-specific information from the base station in response to the request, wherein the request for the UE-specific information is transmitted to the base station via message 3 of a 4-step RA procedure or message A of a 2-step RA procedure, and the UE-specific information can be received from the base station via message 4 of the 4-step RA procedure or message B of the 2-step RA procedure.

For example, the core network may include AMF, UPF, SMF, etc. Communication between the gateway and the core network may be performed based on a NG-C / U interface or a 6G-C / U interface. The function of a base station may be performed by a satellite. In other words, the base station may be located on a satellite. A base station located on a satellite may be a base station-DU (distributed unit), and a base station-CU (centralized unit) may be located within an NG-RAN or 6G-RAN.

FIG. 5a is a block diagram illustrating a first embodiment of a transmission path, and FIG. 5b is a block diagram illustrating a first embodiment of a reception path. Referring to FIGS. 5A and 5B, a transmission path (510) may be implemented in a communication node that transmits a signal, and a reception path (520) may be implemented in a communication node that receives a signal. The transmission path (510) may include a channel coding and modulation block (511), a serial-to-parallel (S-to-P) block (512), an Inverse Fast Fourier Transform (N IFFT) block (513), a parallel-to-serial (P-to-S) block (514), a cyclic prefix (CP) addition block (515), and an up-converter (UC) (516).

Here, N may be a natural number. In the transmission path (510), information bits may be input to a channel coding and modulation block (511). The channel coding and modulation block (511) may perform a coding operation (e.g., a low-density parity check (LDPC) coding operation, a polar coding operation, etc.) and a modulation operation (e.g., a quadrature phase shift keying (QPSK), a quadrature amplitude modulation (QAM), etc.) on the information bits. The output of the channel coding and modulation block (511) may be a sequence of modulation symbols. The S-to-P block (512) can convert modulation symbols in the frequency domain into parallel symbol streams to generate N parallel symbol streams. N can be an IFFT size or an FFT size. The N IFFT block (513) can perform an IFFT operation on the N parallel symbol streams to generate signals in the time domain.

The CP addition block (515) can insert a CP into a signal. The UC (516) can up-convert the frequency of the output of the CP addition block (515) to an RF (radio frequency) frequency. Additionally, the output of the CP addition block (515) can be filtered at the baseband before up-conversion. A signal transmitted from a transmission path (510) may be input to a reception path (520). An operation in the reception path (520) may be the reverse operation of the operation in the transmission path (510). A DC (521) may down-convert the frequency of the received signal to a baseband frequency. A CP removal block (522) may remove a CP from a signal.

In FIGS. 5A and 5B , Discrete Fourier Transform (DFT) and Inverse DFT (IDFT) may be used instead of FFT and IFFT. Each of the blocks (e.g., components) in FIGS. 5A and 5B may be implemented by at least one of hardware, software, or firmware. For example, some of the blocks in FIGS. 5A and 5B may be implemented by software, and the remaining blocks may be implemented by hardware or a “combination of hardware and software.” In FIGS. 5A and 5B , a single block may be subdivided into multiple blocks, multiple blocks may be integrated into a single block, some blocks may be omitted, and blocks supporting other functions may be added.

Referring to FIGS. 7A and 7B , user data and control data (e.g., control information) may be transmitted and received through an interface between a UE and a satellite (e.g., a base station). User data may refer to a user protocol data unit (PDU). The protocol stack of the satellite radio interface (SRI) may be used to transmit and receive user data and / or control data between the satellite and the gateway. User data may be transmitted and received through a GTP (GPRS (general packet radio service) tunneling protocol)-U tunnel between the satellite and the core network. In a non-terrestrial network, a base station can transmit system information (e.g., SIB19) containing satellite assistance information for NTN access. A UE can receive system information (e.g., SIB19) from the base station and check the satellite assistance information included in the system information. The UE can perform communication (e.g., non-terrestrial communication) based on the satellite assistance information. SIB19 can include the information elements (IE)(s) defined in Table 4 below.

IE 'NTN-CovEnh-r18' may include the number of PUCCH repetitions for message 4 hybrid automatic repeat request acknowledgment (HARQ-ACK) (hereinafter, Msg4 HARQ-ACK) and / or a threshold for Msg4 HARQ-ACK. The number of PUCCH repetitions for Msg4 HARQ-ACK (e.g., 'numberOfMsg4HARQ-ACK-Repetitions-r18') may be expressed as a bit string of size 4. The RSRP threshold for Msg4 HARQ-ACK (e.g., 'rsrp-ThresholdMsg4HARQ-ACK-r18') may indicate an RSRP threshold for determining whether to repeat the PUCCH for Msg4 HARQ-ACK. The Msg4 HARQ-ACK may be transmitted from the terminal to the base station according to the random access (RA) procedure described below. As shown in IE 'NTN-CovEnh-r18' in Table 4, for Msg4 HARQ-ACK, a maximum of {1, 2, 4, 8} repetition count candidates can be set. Only one value can be set. Setting only {1} as a single value may not be supported. The repetition count can be expressed as a repetition factor. In one embodiment, the UE may assume that the number of PUCCH repetitions for Msg4 HARQ-ACK (e.g., 'numberOfMsg4HARQ-ACK-Repetitions-r18') and the RSRP threshold for Msg4 HARQ-ACK (e.g., 'rsrp-ThresholdMsg4HARQ-ACK-r18') are set by receiving SIB19. It may be assumed that a 4-step random access (RA) procedure has been initiated at the UE. The terminal can obtain an RSRP value by performing a measurement operation for a synchronization signal of the base station. Based on a comparison result between the obtained RSRP value and the RSRP threshold for Msg4 HARQ-ACK, the terminal can transmit a PUCCH to the base station based on the PUCCH repetition count information for Message 4 HARQ-ACK (e.g., 'numberOfMsg4HARQ-ACK-Repetitions-r18'). If the obtained RSRP value is less than the RSRP threshold for Msg4 HARQ-ACK, the terminal can transmit the PUCCH to the base station repeatedly as many times as the repetition count indicated by the PUCCH repetition count information (e.g., 'numberOfMsg4HARQ-ACK-Repetitions-r18'). If the obtained RSRP value is greater than the RSRP threshold for Msg4 HARQ-ACK, the terminal can transmit a non-repeated PUCCH to the base station. In another embodiment, the UE may receive SIB19 and assume that the number of PUCCH repetitions for Msg4 HARQ-ACK (e.g., 'numberOfMsg4HARQ-ACK-Repetitions-r18') and the RSRP threshold for Msg4 HARQ-ACK (e.g., 'rsrp-ThresholdMsg4HARQ-ACK-r18') are configured. It may be assumed that a 4-step RA procedure is initiated at the UE. Based on the comparison result between the measured RSRP value and the RSRP threshold for Msg4 HARQ-ACK, the UE may transmit a message including a repetition request (e.g., Msg3 of the 4-step RA procedure) to the base station. The terminal can obtain an RSRP value by performing a measurement operation on the synchronization signal of the base station. The terminal can compare the obtained RSRP value with the RSRP threshold for Msg4 HARQ-ACK. If the obtained RSRP value is lower than the RSRP threshold for Msg4 HARQ-ACK, a message including a repetition request (e.g., Msg3 of the 4-step RA procedure) can be transmitted to the base station. In another embodiment, the UE may receive SIB19 and assume that the number of PUCCH repetitions for Msg4 HARQ-ACK (e.g., 'numberOfMsg4HARQ-ACK-Repetitions-r18') and the RSRP threshold for Msg4 HARQ-ACK (e.g., 'rsrp-ThresholdMsg4HARQ-ACK-r18') are configured. It may be assumed that a 4-step RA procedure is initiated at the UE. The base station may send a capability inquiry to the UE as needed. The base station may transmit a message (e.g., Msg3 of the 4-step RA procedure) containing a capability inquiry to the terminal as needed (e.g., when a predefined condition is met). In response to the base station's capability inquiry, the terminal may transmit a message (e.g., Msg3 of the 4-step RA procedure) containing a capability report to the base station. The capability report of the terminal may include information indicating that the terminal supports repeated transmissions and / or frequency hopping on the PUCCH. In the above-described other embodiments and still other embodiments, the base station can set a repetition factor to be used by the terminal through the Msg4 DCI DAI ((downlink assignment index) field. According to the set repetition factor, the terminal can transmit Msg4 HARQ-ACK to the base station. Common PUCCH resource-based PUCCH transmission after Msg4 HARQ-ACK can be transmitted to the base station according to the set repetition factor. In the above-described embodiments, frequency hopping may be applied to PUCCH transmission for Msg4 HARQ-ACK and PUCCH transmission based on common PUCCH resources after Msg4 HARQ-ACK. The terminal may transmit PUCCH transmission for Msg4 HARQ-ACK and PUCCH transmission based on common PUCCH resources after Msg4 HARQ-ACK to the base station by applying frequency hopping. NTN-Config defined in Table 4 may include information element(s) defined in Table 5 below. EphemerisInfo defined in Table 5 may contain information element(s) defined in Table 6 below. In the present disclosure, a method for operating repetitive transmission and frequency hopping based on implicit indication for an uplink control channel in an NTN environment (hereinafter, "a method for determining frequency resources based on UE-specific information") may be proposed. In order to improve NTN uplink coverage, repetitive transmission and frequency hopping may be applied to a UE in a situation where a common PUCCH resource-based PUCCH transmission following Msg4 HARQ-ACK is agreed upon between a base station and a UE. When repetitive transmission and frequency hopping are applied to a UE, the UE may determine a frequency resource arrangement (or allocation) for each of a plurality of PUCCH transmissions (or PUCCH instances) for the PUCCH. The UE-specific information may be expressed as UE-specific information. In the RA procedure, dedicated PUCCH resources may not be allocated to the UE. The UE may transmit a PUCCH containing ACK / NACK information for Msg4 to the base station using common PUCCH resources. The dedicated PUCCH resources may be UE-specific resources allocated based on UE performance. The common PUCCH resources may be resources commonly used by UEs connected to the base station. In an NTN environment, to improve coverage (e.g., improve uplink coverage), if the UE transmits a PUCCH containing ACK / NACK information for Msg4 to the base station using common PUCCH resources, repeated transmission and frequency hopping may be supported. As described above, in the RA procedure, Msg 4 HARQ-ACK and subsequent PUCCHs can be transmitted from the UE to the base station using common PUCCH resources. In the 3rd generation partnership project (3GPP), PUCCH repeated transmissions can be used to improve NTN coverage, which uses the repeated transmission value set to Msg4 PDSCH until dedicated PUCCH resources are allocated to the UE. When PUCCH repeated transmissions are used, an intra-slot frequency hopping mechanism can be applied. When applying repeated transmissions and frequency hopping, the transmission operation method, i.e., how each transmission symbol is allocated to which frequency resource, has not yet been discussed. Although it has been decided to apply the intra-slot frequency hopping mechanism, the operation method of frequency hopping (e.g., how to determine the frequency resource to which a specific transmission symbol is allocated) has not been determined. In the intra-slot frequency hopping mechanism, an intra-slot-based 2-hop method is being considered as a frequency hopping method. To ensure future scalability, an N(≥2)-hop method applicable to both intra- and inter-slots may be required. According to the present disclosure, an operation method for repetitive transmission and frequency hopping for PUCCH transmission can be specified. Specifically, based on essential information for repetitive transmission and frequency hopping operation, the symbol position in each transmission slot, i.e., the frequency resource on which each symbol should be transmitted, can be derived based on the time resource used by each symbol through the corresponding parameters. This derivation process can be further refined by introducing additional messages and information as needed. Through this, the base station and terminal can identify the frequency resource of each symbol to be transmitted later immediately after the parameters are given, and repetitive transmission and frequency hopping for PUCCH transmission can be supported based on this. The essential information for repetitive transmission and frequency hopping operation may be information included in a UE-specific message that is necessarily exchanged between the base station and terminal according to a standard specification (e.g., 3GPP NR standard) before performing PUCCH transmission based on common PUCCH resources. The UE-specific message may be expressed as a terminal-specific message. Msg4 HARQ-ACK may be a message transmitted from the terminal to the base station to indicate that the RA procedure has been successfully performed. Msg4 HARQ-ACK may be transmitted from the terminal to the base station according to the following four-step random access (RA) procedure. Msg4 HARQ-ACK may be expressed as Msg5. FIG. 8 is a flowchart illustrating a four-step random access procedure according to embodiments of the present disclosure. Referring to Figure 8, a communication system may include a base station and a terminal. The terminal may access the base station according to a four-step RA procedure. It may be assumed that the terminal has received system information from the base station, including configuration information for radio resources (e.g., uplink radio resources) for the RA procedure. The base station and the terminal may be configured identically or similarly to the communication node illustrated in Figure 3. In step S810, the terminal may transmit Msg1, including a preamble, to the base station using a physical random access channel (PRACH) established by the base station. The base station may receive Msg1 from the terminal. Msg1 may be expressed as MSG1. In a contention-based random access (CBRA) procedure, a UE can randomly select an RA preamble. In a contention-free random access (CFRA) procedure, a base station can pre-allocate an RA preamble to a UE. In step S820, the base station may transmit Msg2 including a random access response (RAR) to the terminal in response to Msg1 received in step S810. The terminal may receive Msg2 including the RAR from the base station. Msg2 may be transmitted via a physical downlink control channel (PDCCH) and / or a physical downlink shared channel (PDSCH). Msg2 may be expressed as MSG2. The RAR may include timing advance (TA) information indicating timing offset information for UL synchronization, UL resource allocation information (UL grant information), temporary terminal identifiers (e.g., temporary cell-RNTI, TC-RNTI), etc. The terminal may perform step S830 according to the resource allocation information and TA value in the RAR. In step S830, the terminal may transmit Msg3 containing scheduled transmission to the base station. The base station may receive Msg3 containing scheduled transmission from the terminal. Msg3 may be expressed as MSG3. In step S840, the base station may transmit Msg4 containing contention resolution information to the terminal. The terminal may receive Msg4 containing contention resolution information from the base station. Msg4 may be expressed as MSG4. In step S850, the terminal may transmit Msg5, which includes HARQ-ACK (hybrid automatic repeat and request acknowledgment) information for Msg4, to the base station. The base station may receive Msg5, which includes HARQ-ACK information for Msg4, from the terminal. Msg5 may be expressed as MSG5. As illustrated in Fig. 8, Msg4 HARQ-ACK may be a message transmitted from the terminal to the base station to indicate that RA has been successfully performed. Msg4 HARQ-ACK may be transmitted from the terminal to the base station via the physical uplink control channel (PUCCH). If the RRC connection establishment between the base station and the terminal is not completed, Msg4 HARQ-ACK may be transmitted using common PUCCH resources instead of dedicated PUCCH resources for the terminal. In an NTN environment, PUCCH transmission enhancement for Msg4 HARQ-ACK may be considered for UEs to enhance coverage. As mentioned above, Msg4 HARQ-ACK may be transmitted using common PUCCH resources instead of dedicated PUCCH resources. The common PUCCH resources may continue to be used until dedicated PUCCH resources are allocated to the UE. After Msg4 HARQ-ACK transmission, coverage enhancement may be applied to PUCCH transmissions using the common PUCCH resources in the same manner as for Msg4 HARQ-ACK transmissions. Coverage enhancement may also imply uplink coverage enhancement. PUCCH can be used by terminals to transmit uplink control information (UCI), such as HARQ-ACK, to the base station. Formats such as those in Table 7 can be used on PUCCH. In Table 7, when intra-slot frequency hopping is set for PUCCH formats 1, 3, and 4, the number of symbols in the first hop is It could be. can represent the PUCCH transmission length of the OFDM symbol. Before dedicated PUCCH resources are allocated, the UE can use common PUCCH resources. The UE can use the PUCCH resource set provided according to Table 8 for HARQ-ACK transmission. When dedicated PUCCH resources are allocated to the UE, the UE can receive at least one PUCCH resource(s) from the base station via a higher layer (e.g., the RRC layer). Referring to Table 8, a PUCCH resource set can include 16 resources. For PUCCH transmission, each of the 16 resources includes the PUCCH format, the first symbol, the duration, and the PRB offset. and / or may include a cyclic shift (CS) index set. For PUCCH / PUSCH, if interlace transmission is not configured, the terminal can transmit PUCCH using frequency hopping. If interlace transmission is configured, the terminal can transmit PUCCH without using frequency hopping. Whether interlace transmission is configured can be checked through the parameter 'useInterlacePUCCH-PUSCH' in 'BWP-UplinkCommon' in Table 9. The parameter can be expressed as a field or IE. In Table 9, when the parameter 'useInterlacePUCCH-PUSCH-r16' is provided in 'BWP-UplinkCommon', for cell-specific PUSCH (e.g., PUSCH scheduled by RAR UL grant), the UE can use UL frequency domain resource allocation type 2. For cell-specific PUCCH, the UE can use interlaced PUCCH formats 0 and 1. To improve uplink coverage in an NTN environment, PUCCH may be repeatedly transmitted as illustrated in Fig. 9. When repeated transmission is performed for PUCCH, the repetition factor may be 2, and frequency hopping may not be applied. FIG. 9 is a conceptual diagram illustrating a comparison between a case where repetitive transmission is not applied and a case where repetitive transmission is applied to a physical uplink control channel according to embodiments of the present disclosure. Referring to FIG. 9, the first part (910) may represent a case where repeated transmission is not applied to PUCCH format 1 of length 4. The second part (920) may represent a case where the repetition factor is 2 for PUCCH format 1 of length 4. In the second part (920), frequency hopping may not be applied. As illustrated in the second part (920), when repeated transmission is applied to PUCCH format 1, the start symbol in each slot and the number of symbols within each slot may be the same. In an added slot (e.g., slot 1), the same symbols may be transmitted in a temporally repeated manner. For convenience of explanation, one slot includes 14 symbols, but is not limited thereto. Next, for PUCCH transmission, cases where frequency hopping is not applied and cases where frequency hopping is applied will be described. As shown in the first part (910) of FIG. 9, repeated transmission may not be applied to PUCCH format 1 with a length of 4. FIG. 10 is a conceptual diagram illustrating a comparison between a case where repetitive transmission is not applied and a case where repetitive transmission is applied to a physical uplink control channel according to embodiments of the present disclosure. Referring to FIG. 10, the first part (1010) may represent a case where frequency hopping is not applied to a PUCCH format 1 having a length of 4. The second part (1020) may represent a case where 2-hop based frequency hopping is applied to a PUCCH format 1 having a length of 4. As illustrated in the first part (1010), frequency hopping may not be applied to a PUCCH format 1 having a length of 4. The PUCCH may transmit 4 PUCCH symbols using only the first frequency resource. As illustrated in the second part (1020), 2-hop based frequency hopping may be applied to a PUCCH format 1 having a length of 4. The PUCCH may transmit 4 PUCCH symbols using the first frequency resource and the second frequency resource. For convenience of explanation, one slot includes 14 symbols, but is not limited thereto. Next, the notations used in the UE-specific information-based frequency resource determination method will be described. The notations shown in Table 10 may be used in the UE-specific information-based frequency resource determination method. In Table 10, can be expressed as "number of frequency resources applied to hopping, number of frequency resources, hopping factor". can be expressed as a "repetition factor". In a UE-specific information-based frequency resource determination method, the notations shown in Table 10 can be used as shown in FIG. 11. FIG. 11 is a conceptual diagram illustrating notations used in a UE-specific information-based frequency resource determination method in embodiments of the present disclosure. Referring to Figure 11, the subcarrier spacing (SCS) can be assumed to be 15 kHz, and one slot can include 14 symbols. Number of PUCCH symbols per slot can be 4, the total number of frequency resources for frequency hopping can be 2, and the repeat transmission factor can be 2. may represent the first frequency resource (or first frequency resource), may represent the second frequency resource (or second frequency resource). PUCCH starting symbol in each slot can be 10 days. Is It can be, It could be. Is Regardless of It can be decided according to . If it is 10 or 11, can be 1. If it is 12 or 13, can be 2. In Fig. 11, for convenience of explanation, it is assumed that the SCS is 15 kHz, but it is not limited thereto. A UE-specific information-based frequency resource determination method proposed in this disclosure will be described. [UE-Specific Information-Based Frequency Resource Determination Method] In a situation where repetitive transmission and frequency hopping are considered, a UE-specific information-based frequency resource determination method can determine the frequency resources to which each transmission symbol in each slot is allocated for PUCCH transmission on a per-user (or per-terminal) basis using a cell-specific message. The UE-specific information-based frequency resource determination method may have a structure in which steps 1 to 4 are sequentially performed. Each of steps 1 to 4 may be expressed as a procedure or process. - Step 1: Base sequence Creation of; > Basic sequence It can be generated solely through the use of information previously exchanged between the base station and the terminal or through a combination of information previously exchanged between the base station and the terminal. - Step 2: Basic Sequence Pre-hopping sequence for N-hop application from generation; - Step 3: Pre-hopping sequence Hopping sequence from decision; - Step 4: Determined hopping sequence Frequency resources using decision. frequency resources After the PUCCH symbol is determined, the terminal can determine the frequency resource index to be applied to each PUCCH symbol. The terminal can perform repeated transmission and frequency hopping based on the determined frequency resource index. Each of the above-described steps 1 to 4 may be subjected to the following step O at least once prior to execution. - Step O: Change the message (or sequence) value. > An interleaver and / or scrambler may be applied, which may change the message (or sequence) value. A flowchart of a UE-specific information-based frequency resource determination method according to embodiments of the present disclosure can be represented as in FIG. 12. FIG. 12 is a flowchart illustrating a method for determining frequency resources based on UE-specific information according to embodiments of the present disclosure. Referring to FIG. 12, a method for determining frequency resources based on UE-specific information may include steps 1 to 4 (steps S1210 to S1240). In step 1 (step S1210), a basic sequence is determined by using information previously exchanged between a base station and a terminal alone or by combining information previously exchanged between a base station and a terminal. can be generated. Step O (step S1250) is the generated basic sequence An interleaver and / or scrambler can be performed on the step 2 (step S1220). In step O (step S1250), the interleaved and / or scrambled basic sequence Pre-hopping sequence from can be generated. In step 3 (step S1230), the interleaved and / or scrambled pre-hopping sequence in step O (step S1260) Hopping sequence from can be generated. In step 4 (S1240), the interleaved or scrambled hopping sequence in step O (step S1260) Using frequency resources can be determined. As mentioned earlier, frequency resources may represent a frequency resource for transmitting the b-th symbol in slot a. In Fig. 12, the basic sequence , pre-hopping sequence and hopping sequence does not exist or has an existing base sequence , pre-hopping sequence and hopping sequence If the existing basic sequence is not suitable for application, step 1 (step S1210) may be initiated. can be used, and new basic sequences If it is determined that there is no need to generate a pre-hopping sequence, step 2 (step S1220) may be initiated. can be used, and a new pre-hopping sequence If it is determined that there is no need to generate the existing hopping sequence, step 3 (step S1230) may be initiated. can be used, and a new hopping sequence If it is determined that there is no need to generate existing frequency resources, step 4 (step S1240) may be initiated. can be used, and new frequency resources If it is determined that there is no need to generate a UE-specific information-based frequency resource, the execution of each of steps 1 (step S1210) to 4 (step S1240) in the UE-specific information-based frequency resource determination method may be terminated. A frequency resource determination method based on UE-specific information may include a basic sequence generation step (e.g., step 1 (step S1210) in FIG. 12), a pre-hopping sequence generation step (e.g., step 2 (step S1220) in FIG. 12), a hopping sequence generation step (e.g., step 3 (step S1230) in FIG. 12), and a frequency resource determination step (e.g., step 4 (S1240) in FIG. 12). Depending on the application of the UE-specific information-based frequency resource determination method, each step may be omitted. For example, when the input of the previous step is directly used as the output of the next step, a specific step(s) may be omitted. Frequency Resource For generation, only one starting point from each of the basic sequence generation step, pre-hopping sequence generation step, hopping sequence generation step, and frequency resource determination step can be used. In a UE-specific information-based frequency resource determination method, a sequence used in a previous PUCCH transmission may be stored and managed. After the current PUCCH repetition transmission and frequency hopping for the symbol, the newly generated sequence may be compared with the stored sequence during the next PUCCH repetition transmission and frequency hopping. As a result of the comparison, there may be no change in the newly generated sequence and the stored sequence. If necessary, the previous step may be skipped and the process may start from one of steps 2, 3, or 4 (e.g., step 2 (step S1220), step 3 (step S1230), or step 3 (step S1240) in FIG. 13). The base station may be aware of both the message(s) (or information(s)) and the configuration value(s) used by the terminal in the UE-specific information-based frequency resource determination method. The base station may determine the frequency resource based on the message(s) (or information(s)) and the configuration value(s) used by the terminal in the frequency determination method. can be determined. The base station can determine the repetitive transmission and frequency hopping transmission patterns for the PUCCH of the terminal. Next, each step of the UE-specific information-based frequency resource determination method described above will be described. Step 1: Base sequence generation As mentioned before, in step 1, the basic sequence It can be generated by using only the information previously exchanged between the base station and the terminal or by combining the information previously exchanged between the base station and the terminal. Before repeated transmission and frequency hopping are performed in Msg4 HARQ ACK transmission and common PUCCH resource-based PUCCH transmission, the base station and the terminal perform step 1. Basic sequence of base numbers can be generated. In step 1, information that is exchanged between the base station and the terminal and is known to be the same can be used. The basic sequence generation method (e.g., step 1 (S1210) in FIG. 12) can include steps such as those illustrated in FIG. 13. can be a natural number greater than or equal to 2. FIG. 13 is a flowchart illustrating a basic sequence generation method according to embodiments of the present disclosure. Referring to FIG. 13, the basic sequence generation method performs steps S1310 to S1340 by inputting UE-specific message(s) to generate the basic sequence. can be generated. In step S1310, the basic sequence The input message(s) used to generate the basic sequence may be selected. In step S1320, the input message(s) selected in step S1310 may be selected. To fit It can be converted into information of the hexadecimal number. In step S1330, Compensation can be performed on the information converted to a base sequence. In step 1340, the information compensated in step S1330 is combined to form a basic sequence. can be created. In step S1310, the input message(s) are the basic sequence can be selected to generate. The information contained in the cell-specific message(s) may be information commonly known to multiple terminals. Basic sequence When generated using information included in a cell-specific message, the repetitive transmission and frequency hopping pattern for the PUCCH can occur identically for each of a plurality of terminals. The physical resource block (PRB) for the frequency resources of each of the plurality of terminals can be equally allocated. The PUCCH instances (or PUCCH symbols) of each of the plurality of terminals can be simultaneously received by the base station, and the PUCCH instances (or PUCCH symbols) of each of the plurality of terminals can act as interference. To prevent this, information included in UE-specific message(s) having different values ​​for each terminal can be used to determine the frequency resources. As needed, the information included in the cell-specific message(s) can be utilized or partially utilized. The UE-specific message(s) may include RAPID (random access preamble identity) information, C-RNTI (cell radio network temporary identifier) ​​information, and / or contention resolution identity (C-ID) information, which may have different values ​​for each UE. The RAPID information, C-RNTI information, and contention resolution ID information may be information included in message(s) exchanged between the base station and the UE prior to HARQ-ACK transmission in the RA procedure. In addition to the RAPID information, C-RNTI information, and contention resolution ID information, information such as UL-grant and TAC (timing advanced command) included in the RAR message may be included in the basic sequence. can be used to generate. The preamble of Msg1 can be used as information included in a non-binary UE-specific message. The base station can predetermine what information to use, for example, the type of RA procedure (e.g., 2-step RA procedure or 4-step RA procedure) or the frequency hopping factor. Depending on the case, the base station can define a default value. The base station can provide (or transmit) cell-specific message(s) to multiple terminals through the master information block (MIB) / system information block (SIB). Before step S1310 is performed, the base station can define a default sequence. UE-specific message(s) for generating can be transmitted to the terminal. In this case, when two or more pieces of information are used, the method for combining each piece of information can be determined through the default value or UE-specific message(s). After the base station and the terminal determine which information to use in step S1310, the base station and the terminal may perform a conversion process (step S1320). The conversion process may be expressed as a conversion step or a conversion procedure. In step S1320, the base station and the terminal determine the basic sequence of the information. to fit It can be converted to a decimal. As mentioned before, can be a natural number greater than or equal to 2. The information used is the basic sequence If the base station and terminal are different from the base sequence, the base station and terminal may apply step S1320. In other words, the information used is the basic sequence If the base is the same as that of , step S1320 may be omitted. For example, binary base sequence If is considered ( In this case), the selected input message may be Msg1 of the RA procedure. A process of converting the preamble into a sequence of binary digits may be applied. Through the process of converting into a sequence of binary digits, For all input information used, except for input information given in decimal. A base conversion process may be applied. In step S1330, the base station and the terminal can limit the scope of specific information. Through step S1320, After the base station conversion process is performed, the scope of specific information may be limited. If the terminal and base station have a common and accurate understanding of the limited scope of specific information, they can perform a compensation process for that specific information. This may be to prevent future frequency hopping operation results from always being allocated more heavily to certain frequency resources. The compensation process can be expressed as a compensation step or procedure. For example, in the case of RAPID, the number of preamble IDs that can actually be expressed in a total size of 6 bits may be limited to 16 (4 bits) due to the influence of reserved preambles within the cell. The terminal may go through a compensation process (e.g., step S1330 illustrated in FIG. 13). In the compensation process, a particular message (or a particular sequence) is actually (decimal) values ​​can be used. The exchanged message is the entire Among the values ​​of the dog If it has a small size (in decimal), the output sequence of the corresponding information that has gone through the compensation process is has the value of or It can be determined by a sequence of lengths. can represent a rounding operation. can represent a discard operation. is a decimal value cast The result of conversion to a base can be displayed. In this case (in other words, this ), no additional process may be considered. In this case (in other words, this If it is not a power of ), either the rounding operation or the truncating operation can be selected and used depending on the situation. When a discard operation is performed, By the length of After the array is created, a given element, such as the first or last element, may be discarded and used. When a carry operation is performed, can be used as is. Or. Any random number (decimal) In addition to From A sequence of numbers can be generated. Random numbers The range is 0 to It could be a random number The range is 0 to In this case, And It can be. The output sequence has length can be expressed as a random number The generation pattern and rules can be determined by agreement between the base station and the terminal or by pre-definition between the base station and the terminal. After the base station and the terminal perform the compensation process by performing step S1330, the base station and the terminal perform the combining process (step S1340) to perform the basic sequence can be generated. The combining process can be expressed as a combining step or a combining procedure. In step S1340, the base station and the terminal combine the information they have decided to use to determine the basic sequence. can create a basic sequence The length of may vary depending on the amount of information used, the type of information, and / or whether a compensation process is applied. If only one piece of information is selected, the selected message, transformation result and / or compensation result will be the default sequence. can be determined. If two or more messages are selected, the default sequence can be determined through one of the following methods: Method 1, Method 2, or Method 3. - Method 1: Simple concatenation of messages; - Method 2: Combining messages using the XOR (exclusive OR) operation; or - Method 3: Combining messages through simultaneous application of Method 1 and Method 2. Method 1, Method 2 or Method 3 described above can be represented as in Fig. 14. In Method 1 to Method 3, each message can be expressed as a sequence. FIG. 14 is a conceptual diagram illustrating a method for determining a basic sequence in a combining procedure when using multiple input messages according to embodiments of the present disclosure. Referring to Fig. 14, after the compensation procedure is performed, a combination procedure is performed on two binary input messages to obtain the basic sequence can be determined (or generated). In the combining procedure, one of method 1 (1410), method 2 (1420), or method 3 (1430) can be applied. As described above, method 1 (1410) can be a method of simply combining messages (or sequences). Method 2 (1420) can be a method of combining message(s) (or sequence(s)) through an XOR operation. Method 3 (1430) can be a method of applying methods 1 and 2 simultaneously. Basic sequence can be assumed to be a binary sequence. In Fig. 14, for convenience of explanation, the binary basic sequence is assumed but is not limited to this. In Fig. 14, in the compensation procedure, two compensated sequences (a first compensated sequence and a second compensated sequence) can be generated. The first compensated sequence can be expressed as a bit sequence "1010". The second compensated sequence can be expressed as a bit sequence "1111". For the two compensated sequences, when method 1 (1410) is applied, the combining procedure generates a base sequence can be generated (or determined) as a bit sequence ("10101111") which is a simple combination of the first compensated sequence ("1010") and the first compensated sequence ("1111"). When method 2 (1420) is applied, the combination procedure uses the base sequence The bit sequence ("0101") can be generated (or determined) through the XOR operation of the first compensated sequence ("1010") and the second compensated sequence ("1111"). When method 2 (1420) is applied, the combining procedure uses the base sequence The bit sequence (“101011110101”) can be generated (or determined) as a combination of the bit sequence (“10101111”) generated (or determined) in Method 1 and the bit sequence (“0101”) generated (or determined) in Method 2. As illustrated in Fig. 14, Method 1 can be applied to increase the length of the basic sequence. Two pieces of information and is the basic sequence can be used to generate (or determine) the basic sequence Is , , or It could be one of them. is information Next information It may be a way to combine . is information Next information It may be a way to combine . is information Elements and information of It may be a method of combining elements alternately. is information Elements and information of It may be a method of combining elements alternately. The multiple sequences applied in Method 1 may be different. In Method 1, a sequence of relatively short length may be repeatedly applied. Alternatively, one element of a relatively short sequence may be applied to each of multiple elements of a relatively long sequence. In Method 1 (1410) of FIG. 14, a combination of two sequences is illustrated for convenience of explanation, but the present invention is not limited thereto. In other words, Method 1 (1410) of FIG. 14 may also be applied to a combination of two or more pieces of information. A sequence may be expressed as information. As illustrated in Figure 14, Method 2 can combine two sequences through an XOR operation. In this case, Method 2 can be applied, and the value of the binary base sequence can be changed. To obtain more diverse base sequences within a given length, Method 2 can be applied. In method 2, the basic sequence To generate (or determine) two sequences and can be used. Basic sequence Is can be expressed as can represent an XOR operation. In method 2, the multiple sequences applied may be different. In method 2, a sequence of a relatively short length can be repeatedly applied. For each multiple elements of a relatively long sequence, one element of the relatively short sequence can be applied to the XOR operation. Or, one element of the relatively short sequence can be applied to the XOR operation only for one element among the multiple elements of the relatively long sequence. In method 2, other logical operations such as AND, OR, NAND, and XNOR can be applied instead of the XOR operation. Next, embodiments for the above-described step 1 will be described. FIG. 15 is a conceptual diagram illustrating a method for generating a basic sequence according to the present disclosure. Referring to FIG. 15, in order to generate a basic sequence, step 1 may include an input message step (e.g., step S1310 shown in FIG. 13), a conversion procedure step (e.g., step S1320 shown in FIG. 13), a compensation procedure step (e.g., step S1330 shown in FIG. 13), and a combining procedure step (e.g., step S1340 shown in FIG. 13). In the first embodiment (1510), It can be. In the second embodiment (1520), It can be. In the third embodiment (1530), It could be. In the first embodiment (1510), step 1 is a binary sequence (e.g., 000000 (2) ) as input to a binary base sequence. (For example, 000000 (2) ) can be created (or determined). In the second embodiment (1520), step 1 is a 4-ary sequence (e.g., 0123 (4) ) using binary base sequence (For example, z= 00011011 (2) ) can be generated (or determined). In the second embodiment (1520), the conversion procedure step included in step 1 (e.g., step S1320 shown in FIG. 13)) is a 4-ary sequence (e.g., 0123 (4) ) for input binary sequence (e.g. 00011011) (2) ) can be created (or determined). In the third embodiment (1530), step 1 is a 4-bit sequence and a binary sequence (e.g., 0123 (4) , 10110100 (2) ) as input to a 4-ary base sequence. (For example, z = 01232310 (4) ) can be generated (or determined). The conversion procedure step included in step 1 (e.g., step S1320 shown in FIG. 13)) is a 4-ary sequence (e.g., 0123 (4) ) and binary sequences (e.g., 10110100 (2) ) for input of a 4-bit sequence (e.g., 0123) (4) , 2310 (4) ) can be created (or determined). Next, step 2 of the UE-specific information-based frequency resource determination method described above will be described. Step 2: Pre-hopping sequence generation Given as input Jin basic sequence For N-hop application, in step 2, Jinsu's pre-hopping sequence can be generated (or determined). Step 2 can be represented as in Fig. 16. FIG. 16 is a flowchart illustrating a method for determining a pre-hopping sequence according to embodiments of the present disclosure. Referring to Figure 16, the pre-hopping sequence determination method is a basic sequence Pre-hopping sequence by applying direct conversion method or indirect conversion method can be generated (or determined). In the method for determining the pre-hopping sequence, if the direct conversion method can be applied, the pre-hopping sequence is the basic sequence cast Jinsu's pre-hopping sequence can be converted to . If the indirect conversion method can be applied, the pre-hopping sequence can be obtained from a table. A table can store and manage multiple sequences. A base sequence is included in a sequence in a table. can be corresponded to. As shown in Fig. 13. Basic sequence can be generated (or determined) by performing steps S1310 to S1340. The table can be expressed as a conversion table. In step S1610, the basic sequence Pre-hopping sequence for As a method for generating (or determining) the base station and the terminal, each can determine whether to apply the direct conversion method or the indirect conversion method. The direct conversion method is the basic sequence Pre-hopping sequence for If it is determined that the method is applied to generate (or determine) the indirect conversion method, step S1620 may be performed. The indirect conversion method is a basic sequence Pre-hopping sequence for If it is determined that the method is to be applied to generate (or determine) , step S1620 may be performed. In step S1620, the input basic sequence Is Jinsu's pre-hopping sequence can be converted into a pre-hopping sequence Is can be modeled as Is Enter the base number The process of converting to a base can be represented. In the direct conversion method, Jin basic sequence Pre-hopping sequence where one of the elements on the right or the left is assumed to be the highest digit can be converted. For example, in a binary base sequence, one of the bits, the least significant bit (LSB) or the most significant bit (MSB), can be converted assuming it to be the highest digit. In this case, the input basic sequence is a pre-hopping sequence can be used as a pre-hopping sequence. In other words, is the basic sequence It can be ( ). In step S1630, the basic sequence Separate according to the values ​​indicated by A sequence of bases can be mapped. Multiple Numeric sequences can be stored and managed in tables. Base sequences and base sequences Corresponding to The base station and terminal may have predefined or agreed upon sequences in advance. The hexadecimal sequences are " "A set of hexadecimal sequences" or " can be expressed as a "set of true sequences". Multiple Each of the hexadecimal sequences can be a quasi-orthogonal sequence such as a pseudo-random (PN) sequence or an orthogonal sequence such as a Hadamard sequence. As shown in Figure 16, the basic sequence Applying the direct conversion method (e.g., performing step S1620 in Fig. 16) Jinsu's pre-hopping sequence can be converted into . The direct conversion method can be represented as in Fig. 17. FIG. 17 is a conceptual diagram illustrating a method of converting a basic sequence into a pre-hopping sequence by applying a direct conversion method according to embodiments of the present disclosure. Referring to Figure 17, the basic sequence (1710) may be a binary base sequence. Binary base sequence may contain the bit sequence "10101101".

The terminal can transmit a message (e.g., Msg3) including a request for UE-specific parameter(s) used in a UE-specific information-based frequency resource determination method to the base station. The base station can transmit a message (e.g., Msg4) including the UE-specific parameter(s) to the terminal in response to the terminal request. In Table 26, Embodiments L and M may be UE-specific information-based frequency resource determination methods combining cell-specific messages, terminal requests, and / or UE-specific messages. In embodiment L, the base station may transmit a cell-specific message (e.g., SIB1, SIB19, etc.) to the terminal. The terminal may transmit a message (e.g., Msg3) to the base station including a request for UE-specific parameter(s) used in a UE-specific information-based frequency resource determination method. In response to the terminal request, the base station may transmit a message (e.g., Msg4) including the UE-specific parameter(s) to the terminal. In embodiment L, the base station can transmit a cell-specific message (e.g., SIB1, SIB19, etc.) to the terminal. The terminal can transmit a message (e.g., MsgA) to the base station containing a request for UE-specific parameter(s) used in a UE-specific information-based frequency resource determination method. In response to the terminal request, the base station can transmit a message (e.g., MsgB) containing the UE-specific parameter(s) to the terminal. Next, a PUCCH transmission method using a UE-specific information-based frequency resource determination method in a communication system will be described. Duplicate and similar descriptions may be omitted. The communication system may include an NTN. In step S3310, for repeated transmission and frequency hopping of PUCCH, the terminal can receive PUCCH configuration information for repeated transmission and frequency hopping from the base station. PUCCH configuration information may include repetition factor information, hopping factor information, PUCCH symbol information included in a slot, PUCCH start symbol position information within a slot, and / or hopping sequence start offset information. The repetition factor information may include a value indicating the number of repeated transmissions (e.g., in Table 10). ) may be included. The hopping factor information is a value indicating the number of frequency resources (or total number of resource frequencies) applied to hopping (e.g., in Table 10). ) may include, the PUCCH symbol information included in the slot is a value indicating the number of PUCCH symbols per slot (e.g., in Table 10). ) may be included. The PUCCH start symbol position information within the slot is a value indicating the PUCCH start symbol position in each slot (e.g., in Table 10). ) may be included. The hopping sequence start offset information is a value indicating the hopping sequence start offset (e.g., in Equation 3). ) may be included. The terminal may initiate or trigger an RA procedure. If the RA procedure is performed, steps S3320 to S3340 may be performed. In step S3320, the base station may transmit a message including UE-specific information to the terminal in the RA procedure, and the terminal may receive a message including UE-specific information from the base station to the terminal in the RA procedure, thereby obtaining UE-specific information. In step S3330, the base station may transmit a PDSCH to the terminal in the RA procedure. The terminal may receive the PDSCH from the base station in the RA procedure. As illustrated in FIG. 8, according to the RA procedure, the base station can receive messages of the RA procedure (e.g., Msg1, Msg3, Msg4 HARQ-ACK in FIG. 8) from the terminal. The base station can transmit messages of the RA procedure (e.g., Msg2, Msg4 in FIG. 8) to the terminal. The terminal can receive messages of the RA procedure (e.g., Msg1, Msg3, Msg4 HARQ-ACK in FIG. 8) from the base station. The messages of the RA procedure can be transmitted via PDSCH. The terminal can generate HARQ-ACK feedback information for the received messages of the RA procedure (e.g., Msg4 in FIG. 8). As mentioned above, UE-specific information may be information contained in UE-specific messages (or messages) that have different values ​​for each user (or terminal). For example, UE-specific information may include RAPID information, C-RNTI information, collision resolution ID information, UL grant information, TAC information, etc. PUCCH configuration information and UE-specific information can be transmitted and received between the base station and the terminal, as shown in Tables 21 to 26. In step S3340, the terminal may transmit a PUCCH including HARQ-ACK feedback information of the PDSCH to the base station based on PUCCH configuration information and UE-specific information. The base station may receive a PUCCH including HARQ-ACK feedback information of the PDSCH from the terminal. The HARQ-ACK of the PDSCH may mean Msg4 HARQ-ACK. A PUCCH may be a common PUCCH that includes one or more PUCCH transmissions. As illustrated in Equation 3, frequency resources for transmitting each of the one or more PUCCH transmissions to the base station may be determined using PUCCH symbol information included in the slot, PUCCH start symbol position information within the slot, repetition factor information, hopping sequence start offset information, and / or hopping sequence information. As illustrated in FIG. 12, to determine a frequency resource for transmitting one or more PUCCH transmissions to the base station, the terminal may perform steps 1 to 4. To receive one or more PUCCH transmissions from the terminal, the base station may perform steps 1 to 4. If steps 1 to 4 are performed, step O may be further included. In step O, the interleaver and / or scrambler may decode the base sequence. , pre-hopping sequence and / or hopping sequence can be applied to. In determining the frequency resources of each of one or more PUCCH transmissions, a starting offset may be applied to the hopping sequence. The starting offset may be one of a first starting offset, a second starting offset, or a third starting offset. As mentioned above, the first start offset can be 0 or a non-zero constant. The first start offset can be a predefined start offset. The second start offset can be a random number. The second start offset can be a start offset that changes over time. The third start offset can be a hopping sequence used in a previous PUCCH repetition transmission. The next element of the last element may be a value that is used for the first PUCCH symbol in the current PUCCH transmission. The third start offset may be a start offset corresponding to the value of the last element of the previous hopping sequence. As described above, additional information may be required in each of steps 1 to 4. The PUCCH configuration information may further include additional information required in each of steps 1 to 4. In the method for transmitting PUCCH using a frequency resource determination method based on UE-specific information, steps S3310 to S3340 are described individually, but this is not intended to limit the order in which the steps are performed, and if necessary, each step may be performed simultaneously, in a different order, or the steps may be combined. When a UE-specific information-based frequency resource determination method is applied, the average received SNR of PUCCH symbols can be improved. Repeated PUCCH transmissions along the time axis can be implemented in a specific manner. After repeated PUCCH transmissions, the average received SNR of PUCCH symbols can be improved through a combining process at the base station. Consequently, signals from terminals transmitting from longer distances can be successfully received, improving coverage. When a frequency resource determination method based on UE-specific information is applied, diversity gains of PUCCH symbols can be obtained. For repeated transmission and frequency hopping, PUCCH can be transmitted by hopping to multiple frequency resources across multiple slots. In a time and frequency selective mobile fading channel environment, time diversity and frequency diversity gains can be increased through a combining process at the base station. Consequently, the frequency of occurrence of situations in which the instantaneous received SNR of a PUCCH signal transmitted by a terminal suddenly deteriorates due to deep fading can be reduced, and coverage can be improved. When a UE-specific information-based frequency resource determination method is applied, efficient PUCCH repetitive transmission and frequency hopping can be implemented. Specific symbol-specific frequency allocation schemes during repetitive transmission and frequency hopping according to a given hopping pattern can be derived using formulas based on environmental parameters. In this process, the given parameters can be specified by the base station / network depending on the situation, or default values ​​or derived values ​​derived from other parameters can be used to reduce signaling overhead. Depending on the situation, specific implementations of various forms of repetitive transmission and frequency hopping can be directed using only the necessary or allowable amount of signaling overhead. This can contribute to the application of efficient coverage enhancement methods in NTN environments. When a UE-specific information-based frequency resource decision method is applied, diversity enhancement and processing overhead during PUCCH repetitive transmission and frequency hopping operations can be controlled. The number of hoppings can be adjusted, allowing for selective adjustments between achieving additional diversity through more hopping during frequency hopping and reducing processing overhead during transmission and reception through fewer hopping. When a UE-specific information-based frequency resource determination method is applied, user multiplexing can be achieved during PUCCH repetitive transmissions and frequency hopping operations. Because the number and timing of hopping can be adjusted, individual UEs using shared PUCCH resources can avoid using the same frequency resources for repetitive transmissions and frequency hopping. The operations of the method according to the present disclosure can be implemented as a computer-readable program or code on a computer-readable recording medium. A computer-readable recording medium includes any type of recording device that stores information readable by a computer system. Furthermore, a computer-readable recording medium can be distributed across network-connected computer systems, allowing the computer-readable program or code to be stored and executed in a distributed manner. Additionally, the computer-readable recording medium may include hardware devices specifically configured to store and execute program instructions, such as ROM, RAM, flash memory, etc. The program instructions may include not only machine language codes produced by a compiler, but also high-level language codes that can be executed by a computer using an interpreter, etc. While some aspects of the present disclosure have been described in the context of a device, they may also represent a description of a corresponding method, wherein a block or device corresponds to a method step or a feature of a method step. Similarly, aspects described in the context of a method may also be described as a corresponding block or item or a feature of a corresponding device.
