1 / 75 “METHOD FOR OPERATING DEVICE AND DEVICE USING THE METHOD IN A WIRELESS COMMUNICATION SYSTEM” FIELD OF THE INVENTION

[001] This description refers to a method for operating a device in a wireless communication system and to a device using the method. FUNDAMENTALS OF THE INVENTION

[002] As more and more communication devices demand greater communication capacity, there is a need for enhanced mobile broadband communication compared to existing radio access technology. Furthermore, massive machine-type communications (MTC), which provide diverse services connecting various devices and objects, are a key issue to be considered in next-generation communication. In addition, the design of communication systems considering reliability / latency-sensitive services / UEs is being discussed. The introduction of next-generation radio access technology, considering enhanced mobile broadband communication (eMBB), massive MTC (mMTC), and ultra-reliable low-latency communication (URLLC), is discussed. This new technology may be referred to as new radio access technology (new RAT or NR) in the present description for convenience.

[003] In NR or post-NR wireless communication systems, full duplex (FD) operation can be performed. When performing FD operation, downlink reception and uplink transmission can occur simultaneously in a given time resource. Half duplex (HD) operation differs in that only one of downlink reception and uplink transmission can be performed in a given time resource. For FD operation, i) some frequency resources in the same time resource can be allocated as downlink sub-bands and other frequency resources as uplink sub-bands (this can be called sub-band FD or SBFD (full duplex per sub-band)), or ii) frequency resources that Petition 870250089387, dated 10 / 01 / 2025, page 11 / 121 2 / 75 can be used for both downlink reception and uplink transmission in the same time resource can be allocated (this can be called Shared Spectrum FD or SSFD (full duplex with spectrum sharing)).

[004] Within a specific slot, SBFD symbols that operate as SBFD and non-SBFD symbols that do not operate as SBFD can coexist. In this case, resources for uplink data channel transmission can be configured / allocated to include both SBFD and non-SBFD symbols. Thus, since each symbol can present differences in transmissible frequency resources, transmission power, and transmission beamwidth, problems may arise when a user equipment (UE) transmits an uplink data channel using both SBFD and non-SBFD symbols. SUMMARY OF THE INVENTION

[005] Technical Problem

[006] The technical problem to be solved by the present description is to provide a method for operating a device in a wireless communication system and a device using the method.

[007] Technical Solution

[008] A method for operating a device in a wireless communication system and a device using the method are provided. According to the method, a user equipment (UE) receives information used to configure parameters of an uplink data channel applicable to a specific frequency band and performs a repeat transmission of the uplink data channel based on that information. In the repeat transmission, based on the inclusion of full-duplex (FD) and half-duplex (HD) timing features in the timing features configured for the transmission of a specific uplink data channel, the transmission of the specific uplink data channel is skipped.

[009] In another aspect, a UE, a device and a readable medium are provided. Petition 870250089387, dated 10 / 01 / 2025, page 12 / 121 3 / 75 per computer to run the above method.

[010] In another aspect, a method is provided for operating a base station and a base station using the method. According to the base station operation method, the base station transmits, to a user equipment (UE), information used to configure parameters of an uplink data channel applicable to a specific frequency band and performs a repeat reception of the uplink data channel based on this information. In the repeat reception, based on the inclusion of full duplex (FD) and half duplex (HD) time features in the time features configured for the reception of a specific uplink data channel, the reception of the specific uplink data channel is skipped. ADVANTAGEOUS EFFECTS

[011] According to the method described herein, by transmitting each PUSCH using only symbols of the same type, it is possible to prevent the frequency resources, transmission power, transmission beams, etc. for PUSCH transmission from changing depending on the transmission symbol.

[012] This can reduce the complexity of PUSCH transmission and increase the efficiency of PUSCH transmission. BRIEF DESCRIPTION OF THE DRAWINGS

[045] In this descriptive report, “A or B” may mean “A only”, “B only” or “both A and B”. In other words, in this descriptive report, “A or B” may be interpreted as “A and / or B”. For example, in this report Petition 870250089387, dated 10 / 01 / 2025, page 15 / 121 6 / 75 descriptive, “A, B or C” may mean “only A”, “only B”, “only C” or “any combination of A, B and C”.

[046] A slash ( / ) or comma used in this descriptive report may mean “and / or”. For example, “A / B” may mean “A and / or B”. Consequently, “A / B” may mean “A only”, “B only” or “A and B”. For example, “A, B and C” may mean “A, B or C”.

[047] In this descriptive report, “at least one of A and B” may mean “only A”, “only B” or “A and B”. Furthermore, in this descriptive report, the expression “at least one of A or B” or “at least one of A and / or B” may be interpreted as “at least one of A and B”.

[048] In addition, in this descriptive report, “at least one of A, B and C” may mean “only A”, “only B”, “only C” or “any combination of A, B and C”. Furthermore, “at least one of A, B or C” or “at least one of A, B and / or C” may mean “at least one of A, B and C”.

[049] Furthermore, parentheses used in this descriptive report may mean “for example”. Specifically, when indicated as “control information (PDCCH)”, it may mean that “PDCCH” is proposed as an example of “control information”. In other words, the “control information” in this descriptive report is not limited to “PDCCH”, and “PDCCH” may be proposed as an example of “control information”. In addition, when indicated as “control information (i.e., PDCCH)”, it may also mean that “PDCCH” is proposed as an example of “control information”.

[050] The technical characteristics described individually in a figure in this descriptive report can be implemented individually or simultaneously.

[051] Figure 1 illustrates a wireless communication system to which the present description can be applied. This can also be called E-UTRAN (Network of Petition 870250089387, dated 10 / 01 / 2025, page 16 / 121 7 / 75 Access via Terrestrial Radio (Evolved UMTS) or LTE (Long Term Evolution) / LTE-A system.

[052] E-UTRAN includes a base station (BS) 20 that provides a control plane and a user plane for a user equipment (UE) 10. The UE 10 can be fixed or mobile, and may be referred to by other terminology, such as mobile station (MS), user terminal (UT), subscriber station (SS), mobile terminal (MT), wireless device, terminal, etc. The BS 20 is generally a fixed station that communicates with the UE 10 and may be referred to by other terminology, such as evolved Node-B (eNB), base transceiver system (BTS), access point, etc.

[053] The BSs are interconnected via an X2 interface. The BSs are also connected via an S1 interface to an evolved packet core (EPC) 30, more specifically, to a mobility management entity (MME) via S1-MME and to a service gateway (S-GW) via S1-U.

[054] EPC 30 includes an MME, an S-GW, and a packet data network gateway (P-GW). The MME holds UE access information or UE capacity information, and such information is generally used for UE mobility management. The S-GW is a gateway that has an E-UTRAN as its endpoint. The P-GW is a gateway that has a PDN as its endpoint.

[055] The layers of a radio interface protocol between the UE and the network can be classified into a first layer (L1), a second layer (L2), and a third layer (L3), based on the three lower layers of the Open Systems Interconnection (OSI) model, well known in communication systems. Among them, a physical layer (PHY) belonging to the first layer provides an information transfer service using a physical channel, and a radio resource control (RRC) layer belonging to the third layer serves to control a radio resource between the UE and the network. For this, the RRC layer exchanges an RRC message between the UE and the BS. Petition 870250089387, dated 10 / 01 / 2025, page 17 / 121 8 / 75

[056] Figure 2 is a block diagram showing the radio protocol architecture for the user plane. Figure 3 is a block diagram showing the radio protocol structure for the control plane. The user plane is a protocol stack for transmitting user data. The control plane is a protocol stack for transmitting control signals.

[057] With reference to Figure 2 and Figure 3, a PHY layer provides an upper layer (= higher layer) with a service for transferring information through a physical channel. The PHY layer is connected to a medium access control (MAC) layer, which is a layer above the PHY layer, through a transport channel. Data is transferred between the MAC layer and the PHY layer through the transport channel. The transport channel is classified according to how and with what characteristics the data is transferred through a radio interface.

[058] Data is moved between different PHY layers, that is, the PHY layers of a transmitter and a receiver, through a physical channel. The physical channel can be modulated according to an Orthogonal Frequency Division Multiplexing (OFDM) scheme and use time and frequency as radio features.

[059] The functions of the MAC layer include mapping between a logical channel and a transport channel, as well as multiplexing and demultiplexing for a transport block provided through a physical channel into the transport channel of a Service Data Unit (SDU) MAC belonging to a logical channel. The MAC layer provides service to a Radio Link Control (RLC) layer through the logical channel.

[060] The functions of the RLC layer include the concatenation, segmentation, and reassembly of an RLC SDU. To guarantee the various types of Quality of Service (QoS) required by a Radio Carrier (RB), the RLC layer provides three types Petition 870250089387, dated 10 / 01 / 2025, page 18 / 121 9 / 75 operating mode: Transparent Mode (TM), Unacknowledged Mode (UM), and Acknowledged Mode (AM). The AM RLC provides error correction through an Automatic Retry Request (ARQ).

[061] The RRC layer is defined only in the control plane. The RRC layer is related to the configuration, reconfiguration, and release of radio carriers, being responsible for the control of logical channels, transport channels, and PHY channels. An RB means a logical route provided by the first layer (PHY layer) and the second layers (MAC layer, RLC layer, and PDCP layer) to transfer data between the UE and a network.

[062] The function of a Packet Data Convergence Protocol (PDCP) layer in the user plane includes the transfer of user data and header compression and encryption. The function of the PDCP layer in the user plane also includes the transfer and encryption / protection of the integrity of control plane data.

[063] Configuring an RB means the process of defining the characteristics of a wireless protocol layer and channels to provide a specific service and configuring each detailed parameter and method of operation. An RB can be divided into two types: Signaling RB (SRB) and Data RB (DRB). The SRB is used as a passage through which an RRC message is transmitted in the control plane, and the DRB is used as a passage through which user data is transmitted in the user plane.

[064] If an RRC connection is established between the UE's RRC layer and the RRC layer of an E-UTRAN, the UE will be in the RRC connected state. Otherwise, the UE will be in the RRC idle state.

[065] A downlink transport channel through which data is transmitted from a network to the UE includes a broadcast channel (BCH) through which system information is transmitted and a shared downlink channel (SCH) Petition 870250089387, dated 10 / 01 / 2025, p. 19 / 121 10 / 75 through which user traffic or control messages are transmitted. Traffic or a control message for the multicast or downlink broadcast service can be transmitted through the downlink SCH, or it can be transmitted through an additional downlink multicast channel (MCH). Meanwhile, an uplink transport channel through which data is transmitted from the UE to a network includes a random access channel (RACH) through which an initial control message is transmitted and a shared uplink channel (SCH) through which user traffic or control messages are transmitted.

[066] The logical channels that are placed over the transport channel and mapped to the transport channel include a broadcast control channel (BCCH), a paging control channel (PCCH), a common control channel (CCCH), a multicast control channel (MCCH), and a multicast traffic channel (MTCH).

[067] The physical channel includes several OFDM symbols in the time domain and several subcarriers in the frequency domain. A subframe includes a plurality of OFDM symbols in the time domain. An RB is a resource allocation unit, and includes a plurality of OFDM symbols and a plurality of subcarriers. In addition, each subframe can use specific subcarriers of specific OFDM symbols (e.g., the first OFDM symbol) from the corresponding subframe for a physical downlink control channel (PDCCH), i.e., an L1 / L2 control channel. A Transmission Time Interval (TTI) is a unit of time for subframe transmission.

[068] Next, a new radio access technology (new RAT, NR) will be described.

[069] As more and more communication devices require greater communication capacity, there is a need for enhanced mobile broadband communication compared to existing radio access technology. Furthermore, Petition 870250089387, dated 10 / 01 / 2025, page 20 / 121 11 / 75 Massive machine-type communications (MTC), which provide diverse services connecting various devices and objects, are a key issue to be considered in next-generation communication. Furthermore, the design of communication systems considering reliability / latency-sensitive services / UEs is being discussed. The introduction of next-generation radio access technology, considering enhanced mobile broadband communication (eMBB), massive MTC (mMTC), and ultra-reliable low-latency communication (URLLC), is discussed. This new technology may be referred to as new RAT or NR in this description for convenience.

[070] Figure 4 illustrates the system structure of a next-generation radio access network (NG-RAN) to which NR is applied.

[071] With reference to Figure 4, the NG-RAN may include a gNB and / or an eNB that provides user plane and control plane protocol termination for a UE. Figure 4 illustrates the case of including only gNBs. The gNBs (eNBs) are connected via an Xn interface. The gNB and eNB are connected to a 5G core network (5GC) via an NG interface. More specifically, the gNB and eNB are connected to an access and mobility management (AMF) function via an NG-C interface and connected to a user plane function (UPF) via an NG-U interface.

[072] Figure 5 illustrates a functional division between an NG-RAN and a 5GC.

[073] With reference to Figure 5, gNB can provide functions such as inter-cell radio resource management (Inter Cell RRM), radio carrier management (RB control), connection mobility control, radio admission control, metering configuration and provisioning, dynamic resource allocation, and the like. AMF can provide functions such as NAS security, idle-state mobility handling, and so on. UPF can provide functions such as mobility docking, PDU processing, and the like. SMF can Petition 870250089387, dated 10 / 01 / 2025, page 21 / 121 12 / 75 provides functions such as EU IP address assignment, PDU session control, and so on.

[074] Figure 6 illustrates an example of a frame structure that can be applied in NR.

[075] With reference to Figure 6, in NR, a radio frame (hereinafter also referred to as a frame) can be used in uplink and downlink transmissions. The frame has a length of 10 ms and can be defined as two 5 ms half-frames (HFs). The HF can be defined as five 1 ms sub-frames (SFs). The SF can be divided into one or more slots, and the number of slots within the SF depends on the subcarrier spacing (SCS). Each slot includes 12 or 14 OFDM(A) symbols according to a cyclic prefix (CP). In the case of using a normal CP, each slot includes 14 symbols. In the case of using an extended CP, each slot includes 12 symbols. In this case, a symbol may include an OFDM symbol (or CP-OFDM symbol) and a Single Carrier-FDMA (SC-FDMA) symbol (or Discrete Fourier Transform-OFDM (DFT-s-OFDM) symbol).

[076] Table 1 below illustrates a μ subcarrier spacing configuration. [Table 1] μ Af = 2M5[kHz] Cyclic Prefix (CP) 0 15 Normal 1 30 Normal 2 60 Extended Normal 3 120 Normal 4 240 Normal

[077] Table 2 below illustrates the number of slots in a frame (Nframe'Mslot), the number of slots in a subframe (Nsubframe'Mslot), the number of symbols in a slot (Nslotsymb) and the like, according to the subcarrier spacing settings μ. [Table 2] Petition 870250089387, dated 10 / 01 / 2025, page 22 / 121 13 / 75 μ Nslotsymb Nframe^slot Msubframe.pslot 0 14 10 1 1 14 20 2 2 14 40 4 3 14 80 8 4 14 160 16

[078] Figure 6 illustrates a case of μ = 0, 1, 2, 3.

[079] Table 2-1 below illustrates that the number of symbols per slot, the number of slots per frame, and the number of slots per subframe vary depending on the SCS, in the case of using an extended CP. [Table 2-1] __________________________________________________________ SCS(15*2M) Nslotsymb Nframe- μ slot Msubframe, μ slot 60KHz (μ = 2) 12 40 4

[080] In an NR system, OFDM(A) numerologies (e.g., SCS, CP length, and so on) can be configured differently among a plurality of cells integrated into a UE. Consequently, a duration (of absolute time) of a time resource (e.g., SF, slot, or TTI) (for convenience, collectively referred to as a time unit (TU)) configured with the same number of symbols can be configured differently among the integrated cells.

[081] Figure 7 illustrates a slot structure.

[082] A slot can include a plurality of symbols in a time domain. For example, in the case of a normal CP, a slot can include 14 symbols (or 7 symbols). However, in the case of an extended CP, a slot can include 12 symbols (or 6 symbols). A carrier can include a plurality of subcarriers in a frequency domain. A feature block (RB) can be defined as a plurality of consecutive subcarriers (e.g., 12 subcarriers) in the frequency domain. A bandwidth portion (BWP) can be defined as a plurality of consecutive (physical) feature blocks ((P)RBs) in the frequency domain. Petition 870250089387, dated 10 / 01 / 2025, p. 23 / 121 14 / 75 sequence, and the BWP can correspond to a numerology (e.g., SCS, CP length, and so on). The carrier can include up to N (e.g., 5) BWPs. Data communication can be performed via an active BWP, and only one BWP can be activated for a UE. In a feature grid, each element can be called a feature element (RE), and a complex symbol can be mapped to it.

[083] A physical downlink control channel (PDCCH) may include one or more control channel elements (CCEs), as illustrated in Table 3 below. [Table 3] Aggregation Level Number of CCEs 1 1 2 2 4 4 8 8 16 16

[084] That is, PDCCH can be transmitted via a feature that includes 1, 2, 4, 8, or 16 CCEs. Here, the CCE includes six groups of feature elements (REGs), and a REG includes a feature block in a frequency domain and an orthogonal frequency division multiplexing (OFDM) symbol in a time domain.

[085] Monitoring involves decoding each PDCCH candidate according to a downlink control information (DCI) format. The UE monitors a set of PDCCH candidates in one or more CORESETs (to be described below) in an active BWP DL of each activated service cell in which PDCCH monitoring is configured, according to a corresponding search space set.

[086] A new unit called control resource set (CORESET) can be introduced in NR. The UE can receive a PDCCH in CORESET.

[087] Figure 8 illustrates CORESET. Petition 870250089387, dated 10 / 01 / 2025, page 24 / 121 15 / 75

[088] With reference to Figure 8, CORESET includes Ncoresetrb, the number of feature blocks in the frequency domain, and NCORESETsymb and {1, 2, 3}, the number of symbols in the time domain. Ncoresetrb and NCORESETsymb can be provided by a base station via upper-layer signaling. As illustrated in Figure 8, a plurality of CCEs (or REGs) can be included in the CORESET.

[089] The UE may attempt to detect a PDCCH in units of 1, 2, 4, 8 or 16 CCEs in the CORESET. One or a plurality of CCEs in which PDCCH detection may be attempted may be referred to as PDCCH candidates.

[090] A plurality of CORESETs can be configured for the UE.

[091] A control region in the wireless communication system of the related technique (e.g., LTE / LTE-A) is configured across the entire system BW used by a base station (BS). All UEs, excluding some (e.g., eMTC / NB-IoT UEs) that only support a narrowband, must be able to receive wireless signals from the entire system BW of the BS to properly receive / decode the control information transmitted by the BS.

[092] On the other hand, in NR, the CORESET described above was introduced. The CORESET consists of radio resources for control information to be received by the UE and can use only a portion, rather than the entire system bandwidth. The BS can allocate the CORESET to each UE and transmit control information through the allocated CORESET. In NR, the UE can receive control information from the BS without necessarily receiving the entire system bandwidth.

[093] The CORESET may include an EU-specific CORESET for transmitting EU-specific control information and a common CORESET for transmitting control information common to all EUs.

[094] On the other hand, NR may require high reliability depending on the field of application. In this situation, the target block error rate (BLER) for downlink control information (DCI) transmitted through a control channel. Petition 870250089387, dated 10 / 01 / 2025, page 25 / 121 The 16 / 75 downlink bandwidth (e.g., physical downlink control channel: PDCCH) can be significantly smaller than that of the previous technique. As an example of a method to satisfy the high reliability requirement, the amount of content included in the DCI can be reduced and / or the amount of resources used in the DCI transmission can be increased. At this point, the resources may include at least one of the following: time domain resources, frequency domain resources, code domain resources, and space domain resources.

[095] In NR, the following technologies / resources can be applied.

[096] <Estrutura de subquadro autocontida>

[097] Figure 9 shows an example of a frame structure for a new wireless access technology.

[098] In NR, as shown in Figure 9, a structure in which a control channel and a data channel are time-division multiplexed within a TTI can be considered a frame structure to minimize latency.

[099] In Figure 9, the hatched area represents the downlink control area and the black area represents the uplink control area. An unmarked area can be used to transmit downlink data (DL data) or to transmit uplink data (UL data). The characteristic of this structure is that downlink (DL) and uplink (UL) transmissions occur sequentially within a subframe; DL data can be transmitted within a subframe, and UL ACK / NACK (Acknowledgement / Non-Acknowledgement) can also be received. As a result, the time required to retransmit data when a data transmission error occurs is reduced, thus minimizing the latency of the final data transmission.

[0100] In this TDMed data and control subframe structure, a time slot may be required for a base station and a UE to switch from a transmit mode to a receive mode or from a receive mode to a transmit mode. Petition 870250089387, dated 10 / 01 / 2025, page 26 / 121 17 / 75 transmission mode. For this purpose, some OFDM symbols, at the moment when DL switches to UL, can be defined for a guard period (GP) in the self-contained subframe structure.

[0101] Figure 10 illustrates the structure of a self-contained slot.

[0102] In an NR system, a DL control channel, DL or UL data channel, a UL control channel, and the like may be contained in a slot. For example, the first N symbols (hereinafter, DL control region) in the slot may be used to transmit a DL control channel, and the last M symbols (hereinafter, UL control region) in the slot may be used to transmit a UL control channel. N and M are integers greater than or equal to 0. A resource region (hereinafter, data region) that exists between the DL control region and the UL control region may be used for DL ​​data transmission or UL data transmission. For example, the following configuration may be considered. The respective durations are listed in chronological order.

[0103] 1. DL configuration only,

[0104] 2. UL configuration only,

[0105] 3. Mixed UL-DL configuration:

[0106] DL Region + Guard Period (GP) + UL Control Region,

[0107] DL control region + GP + UL region.

[0108] DL Region: (i) DL data region, (ii) DL control region + DL data region.

[0109] UL Region: (i) UL data region, (ii) UL data region + UL control region.

[0110] A PDCCH can be transmitted in the DL control region, and a shared physical downlink channel (PDSCH) can be transmitted in the DL data region. A shared physical uplink channel (PUCCH) can be transmitted in the UL control region, and a shared physical uplink channel (PUSCH) can be Petition 870250089387, dated 10 / 01 / 2025, page 27 / 121 18 / 75 transmitted in the UL data region. Downlink control information (DCI), for example, DL data scheduling information, UL data scheduling information, and the like, can be transmitted in the PDCCH. Uplink control information (UCI), for example, ACK / NACK information about DL data, channel status information (CSI), and a scheduling request (SR), can be transmitted in the PUCCH. A GP provides a time slot in a process in which a BS and a UE switch from TX mode to RX mode, or a process in which the BS and UE switch from RX mode to TX mode. Some symbols at the time of switching from DL to UL within a subframe can be configured as GP.

[0111] <Formação de feixe analógica #1 >

[0112] Wavelengths are shortened in millimeter waves (mmW), and therefore a large number of antenna elements can be installed in the same area. That is, the wavelength is 1 cm at 30 GHz, and therefore a total of 100 antenna elements can be installed in the form of a two-dimensional array in a 0.5 lambda (wavelength) slot in a 5 x 5 cm panel. Consequently, it is possible to increase the beamforming gain (BF) by using a large number of antenna elements to increase coverage or improve the data transfer rate in mmW.

[0113] In this case, if a transceiver unit (TXRU) is provided to adjust the transmission power and phase per antenna element, frequency-independent beamforming can be performed. However, installing TXRUs for all approximately 100 antenna elements decreases cost-effectiveness. Thus, a method is considered to map a large number of antenna elements to one TXRU and control the beam direction using an analog phase shifter. Such analog beamforming can only form one beam direction in all bands and therefore cannot provide frequency-selective beamforming. Petition 870250089387, dated 10 / 01 / 2025, p. 28 / 121 19 / 75

[0114] Hybrid beamforming (BF) with a number B of TXRUs less than Q antenna elements can be considered an intermediate form of digital BF and analog BF. In this case, the number of beam directions that can be transmitted simultaneously is limited to B, although it depends on a method of connecting the B TXRUs and the Q antenna elements.

[0115] <Formação de feixe analógica #2>

[0116] When a plurality of antennas is used in NR, hybrid beamforming, which is a combination of digital and analog beamforming, is emerging. Here, in analog beamforming (or RF beamforming), one RF end performs pre-coding (or combination) and therefore it is possible to obtain similar performance to digital beamforming by reducing the number of RF chains and the number of D / A (or A / D) converters. For convenience, the hybrid beamforming structure can be represented by N TXRUs and M physical antennas. Then, the digital beamforming for the L data layers to be transmitted at the transmitting end can be represented by an N by L matrix, and the N converted digital signals are converted to analog signals via TXRUs, and the analog beamforming represented by an M by N matrix is ​​applied.

[0117] NR system information can be transmitted via broadcast. In this case, in one symbol, analog beams belonging to different antenna panels can be transmitted simultaneously. A scheme for introducing an RS beam (BRS), which is a reference signal (RS) transmitted by applying a single analog beam (corresponding to a specific antenna panel), is under discussion for measuring a channel by analog beam. The BRS can be defined for a plurality of antenna ports, and each antenna port of the BRS can correspond to a single analog beam. In this case, unlike the BRS, a signal of Petition 870250089387, dated 10 / 01 / 2025, page 29 / 121 20 / 75 synchronization or an xPBCH can be transmitted by applying all analog beams within an analog beam group, so as to be received correctly by any UE.

[0118] In NR, in a time domain, a synchronization signal block (SSB, or also known as synchronization signal and physical broadcast channel (SS / PBCH)) can consist of 4 OFDM symbols indexed from 0 to 3 in ascending order within a synchronization signal block, and a PBCH related to a primary synchronization signal (PSS), secondary synchronization signal (SSS), and demodulation reference signal (DMRS) can be mapped to the symbols. As described above, the synchronization signal block can also be represented by an SS / PBCH block.

[0119] In NR, as a plurality of synchronization signal blocks (SSBs) may be transmitted at different times respectively, and the SSB may be used to perform initial access (IA), service cell measurement and the like, it is preferable to transmit the SSB first when the transmission time and resources of the SSB overlap with those of other signals. For this purpose, the network may transmit the transmission time and resource information of the SSB or indicate them by means of UE-specific RRC signaling.

[0120] In NR, beams can be used for transmission and reception. If the reception performance of a current service beam is degraded, a search process for a new beam through so-called Beam Fault Recovery (BFR) can be performed.

[0121] Since the BFR process is not intended to declare an error or failure of a link between the network and a UE, it can be assumed that a connection to the current service cell is maintained even if the BFR process is executed. During the BFR process, the measurement of different beams (which can be expressed in terms of CSI-RS port or Synchronization Signal Block (SSB) index) configured by the network is performed. Petition 870250089387, dated 10 / 01 / 2025, page 30 / 121 21 / 75 can be executed, and the best beam for the corresponding UE can be selected. The UE can execute the BFR process in such a way that it performs a RACH process related to a beam that produces a good measurement result.

[0122] Now, a state of the transmission configuration indicator (hereinafter, TCI) will be described. The TCI state can be configured for each CORESET of a control channel, and can determine a parameter to determine an RX beam of the UE, based on the TCI state.

[0123] For each DL BWP of a service cell, a UE can be configured for three or fewer CORESETs. In addition, a UE can receive the following information for each CORESET.

[0124] 1) CORESET p index (from 0 to 11, where the index of each CORESET can be determined exclusively among the BWPs of a service cell),

[0125] 2) Initialization value of the DM-RS scrambling sequence of the PDCCH,

[0126] 3) Duration of a CORESET in the time domain (which can be given in symbol units),

[0127] 4) Set of resource blocks,

[0128] 5) CCE to REG mapping parameter,

[0129] 6) Antenna port quasi-colocation, indicating quasi-colocation (QCL) information of a DM-RS antenna port to receive a PDCCH in each CORESET (from a set of antenna port quasi-colocations provided by an upper-layer parameter called 'TCI-State'),

[0130] 7) Indication of the presence of the Transmission Configuration Indication (TCI) field for a specific DCI format transmitted by the PDCCH in the CORESET, and so on.

[0131] QCL will be described. If a characteristic of a channel through which a symbol on an antenna port is transmitted can be inferred from Petition 870250089387, dated 10 / 01 / 2025, page 31 / 121 22 / 75 a channel characteristic through which a symbol on the other antenna port is transmitted, the two antenna ports are said to be quasi-colocalized (QCLed). For example, when two signals A and B are transmitted from the same set of transmitting antennas to which the same / similar spatial filter is applied, the two signals can pass through the same / similar channel state. From the perspective of a receiver, upon receiving one of the two signals, another signal can be detected using a channel characteristic of the received signal.

[0132] In this sense, when it is said that signals A and B are nearly colocalized (QCLed), this may mean that signals A and B have passed through a similar channel condition and, therefore, the channel information estimated to detect signal A is also useful for detecting signal B. Here, the channel condition can be defined according to, for example, a Doppler shift, a Doppler spread, an average delay, a delay spread, a spatial reception parameter or similar.

[0133] A 'TCI-State' parameter associates one or two downlink reference signals with corresponding QCL types (QCL types A, B, C and D, see Table 4). [Table 4] QCL Type Description QCL Type A Doppler shift, Doppler scatter, mean delay, delay scatter QCL Type B Doppler shift, Doppler scatter QCL Type C Doppler shift, mean delay QCL Type D Spatial Rx parameter

[0134] Each 'TCI-State' can include a parameter to configure a QCL relationship between one or two downlink reference signals and a DM-RS port of a PDSCH (or PDCCH) or a CSI-RS port of a CSI-RS resource.

[0135] Meanwhile, for each DL BWP configured for a UE in a service cell, the UE can be provided with 10 (or fewer) sets of search spaces. For each set of search spaces, the UE can be provided with at least one of the following pieces of information. Petition 870250089387, dated 10 / 01 / 2025, page 32 / 121 23 / 75

[0136] 1) search space set index s (0 < s < 40), 2) an association between a CORESET and the search space set s, 3) a PDCCH monitoring periodicity and a PDCCH monitoring offset (slot unit), 4) a PDCCH monitoring pattern within a slot (e.g., indicating a first symbol of a CORSET in a slot for PDCCH monitoring), 5) the number of slots in which the search space set s exists, 6) the number of PDCCH candidates per CCE aggregation level, 7) information indicating whether the search space set s is CSS or USS.

[0137] In NR, a CORESET#0 can be configured by a PBCH (or a dedicated UE signaling for transfer or a PSCell configuration or a BWP configuration). A set of #0 seek spaces (SS) configured by the PBCH can have different monitoring offsets (e.g., a slot offset, a symbol offset) for each associated SSB. This may be necessary to minimize the need for UE monitoring of the seek space. Alternatively, this may be necessary to provide a beam scan control / data region capable of performing control / data transmission based on each beam, so that communication with the UE is persistently performed in a situation where the UE's best beam changes dynamically.

[0138] Figure 11 illustrates physical channels and typical signal transmission.

[0139] With reference to Figure 11, in a wireless communication system, a UE receives information from a BS via a downlink (DL) and the UE transmits information to the BS via an uplink (UL). The information transmitted / received by the BS and the UE includes data and a variety of control information, and there are several physical channels according to the type / purpose of the information transmitted / received by the BS and the UE. Petition 870250089387, dated 10 / 01 / 2025, page 33 / 121 24 / 75

[0140] The UE that is reconnected from an off state or that has recently entered a cell performs an initial cell search operation, such as synchronization adjustment with the BS or similar (S11). To do this, the UE receives a primary synchronization channel (PSCH) and a secondary synchronization channel (SSCH) from the BS to adjust synchronization with the BS and acquire information such as cell identity (ID) or similar. In addition, the UE may receive a physical transmission channel (PBCH) from the BS to acquire broadcast information in the cell. Furthermore, the UE may receive a downlink reference signal (DL RS) in an initial cell search step to identify a downlink channel state.

[0141] Cell search (initial) can be considered a procedure in which the UE obtains time and frequency synchronization with a cell and detects the cell ID. Cell search can be based on the primary synchronization signal and the secondary synchronization signal of the cell, and on the PBCH DMRS.

[0142] After completing the initial cell search, the UE can receive a physical downlink control channel (PDCCH) and a corresponding physical downlink control channel (PDSCH) to acquire more specific system information (S12).

[0143] Next, the UE can execute a random access procedure to complete access to the BS (S13 ~ S16). Specifically, the UE can transmit a preamble via a physical random access channel (PRACH) (S13) and can receive a random access response (RAR) for the preamble via a corresponding PDCCH and PDSCH (S14). Subsequently, the UE can transmit a shared physical uplink channel (PUSCH) using scheduling information in the RAR (S15) and can execute a contention resolution procedure similar to the PDCCH and PDSCH (this can be said to be the process of receiving a contention resolution message) (S16). Petition 870250089387, dated 10 / 01 / 2025, page 34 / 121 25 / 75

[0144] After executing the procedure mentioned above, the UE can perform PDCCH / PDSCH reception (S17) and PUSCH / uplink control physical channel (PUCCH) transmission (S18) as a typical uplink / downlink signal transmission procedure. The control information transmitted by the UE to the BS is called uplink control information (UCI). The UCI includes repeat acknowledgment (ACK) / negative ACK (NACK) and hybrid automatic request (HARQ), scheduling request (SR), channel status information (CSI), or similar. The CSI includes a channel quality indicator (CQI), a pre-coding matrix indicator (PMI), a classification indication (RI), or similar. In general, the UCI is transmitted via the PUCCH. However, when control information and data must be transmitted simultaneously, the UCI can be transmitted via the PUSCH.Furthermore, the UE can transmit the UCI aperiodically via PUSCH, according to a request / instruction from a network.

[0145] In order to allow reasonable battery consumption when bandwidth adaptation (BA) is configured, only one uplink BWP and one downlink BWP, or only a pair of downlink / uplink BWPs for each uplink carrier, can be activated simultaneously in an active service cell, and all other BWPs configured in the UE are deactivated. In the deactivated BWPs, the UE does not monitor the PDCCH and does not perform transmission in the PUCCH, PRACH, and ULSCH.

[0146] For the BA, the RX and TX bandwidths of the UE are not necessarily as wide as the bandwidth of a cell and can be adjusted. That is, it can be commanded so that a width is changed (e.g., reduced for a period of low activity to save energy), a position in a frequency domain is moved (e.g., to increase scheduling flexibility), and a spacing between subcarriers is changed (e.g., to allow different services). A subset of the entire bandwidth of a Petition 870250089387, dated 10 / 01 / 2025, page 35 / 121 The 26 / 75 cell is referred to as the bandwidth portion (BWP), and the BA is acquired by configuring BWP(s) for the UE and notifying it of a currently active BWP among the configured BWPs. When the BA is configured, the UE only needs to monitor the PDCCH on an active BWP. That is, there is no need to monitor the PDCCH on the entire downlink frequency of the cell. An inactive BWP timer (independent of the previously mentioned inactive DRX timer) is used to switch an active BWP to a default BWP. That is, the timer resets when PDCCH decoding is successful, and the switch to the default BWP occurs when the timer expires.

[0147] Next, an integrated access and backhaul (IAB) link will be described. To facilitate the description, a proposed method based on a new RAT (NR) system will be described. However, the scope of the system to which the proposed method is applied is expandable to other systems, such as 3GPP LTE / LTE-A systems, in addition to the NR system.

[0148] One of the potential technologies aimed at enabling future scenarios and applications for cellular network deployment is support for wireless backhaul and relay links, allowing for flexible and highly dense deployment of NR cells without the need to proportionally densify the transport network.

[0149] It is expected that greater bandwidth in NR compared to LTE will be available (e.g., mmWave spectrum) with the native deployment of massive MIMO or multibeam systems, thus creating opportunities for the development and deployment of integrated access and backhaul links. This facilitates the creation of a dense network of NR cells with auto-backhaul in a more integrated way, establishing multiple defined control and data channels / procedures to provide access or access to UEs. Such systems are termed integrated access and backhaul (IAB) links.

[0150] This description defines the following. Petition 870250089387, dated 10 / 01 / 2025, page 36 / 121 27 / 75 [0151 ] - AC(x): an access link between node (x) and the UE(s).

[0152] - BH(xy): a backhaul link between node (x) and node (y).

[0153] In this case, the node can mean a donor gNB (DgNB) or a relay node (RN). Here, the DgNB or donor node can be a gNB that provides a function to support backhaul for IAB nodes.

[0154] When relay node 1 and relay node 2 exist, relay node 1, which is connected to relay node 2 by a backhaul link and relays transmitted and received data to relay node 2, is called the parent node of relay node 2, and relay node 2 is called the child node of relay node 1.

[0155] The technical features described individually in a drawing in this descriptive report can be implemented individually or simultaneously.

[0156] The following drawings have been prepared to explain a specific example of this descriptive report. As the names of specific devices or specific signals / messages / fields described in the drawings are given as examples, the technical characteristics of this descriptive report are not limited to the specific names used in the drawings below.

[0157] <Repetições PUSCH>

[0158] Types A and B of PUSCH repeaters have been introduced into the standard specifications (e.g., NR Rel-15 / 16). Transmission is performed as follows, depending on the type of PUSCH repeater.

[0159] 1) Push-type A repetition

[0160] Figure 12 is an example of a type A PUSCH repeat.

[0161] With reference to Figure 12, type A PUSCH repeat is a slot-based PUSCH repeat transmission, and the repeat is performed with the same initial PUSCH transmission symbol position and PUSCH transmission symbol length for each slot, as illustrated in Figure 12. In this Petition 870250089387, dated 10 / 01 / 2025, page 37 / 121 28 / 75 moment, if there is an invalid symbol that cannot be used for PUSCH transmission between the symbol resources that constitute a specific PUSCH repeat, the transmission of the corresponding PUSCH repeat will be discarded and not executed. For example, when a total of four PUSCH repeat transmissions of Rep0, Rep1, Rep2, and Rep3 are executed in slots N, N+1, N+2, and N+3 (one PUSCH repeat is transmitted in each slot), if the symbol resources that constitute Rep1 include an invalid symbol, the transmission of Rep1 will be discarded, and only the transmissions of Rep0, Rep2, and Rep3 will be executed. Therefore, the actual number of repetitions executed may be less than the configured number.

[0162] For type A PUSCH repeat, frequency hopping can be configured for UE by upper layer parameters. One of two frequency hopping modes can be configured.

[0163] i) Frequency hopping within a slot (intra-slot frequency hopping) is applicable to single-slot and multi-slot PUSCH transmission.

[0164] ii) Inter-slot frequency hopping is applicable to multi-slot PUSCH transmission.

[0165] 2) Push-type B repetition

[0166] Figure 13 is an example of a type B PUSCH repeat.

[0167] With reference to Figure 13, the type B PUSCH repeat is repeated in units of the symbol length in which the actual PUSCH is transmitted. For example, as in (a) of Figure 13, when PUSCH is transmitted over 10 symbols, the PUSCH repeat runs in units of 10 consecutive symbols. At this point, the repeat that determines the transmission time resources of the PUSCH repeat without considering slot limits, invalid symbols, etc., is called the nominal repeat. (a) Figure 13 shows an example in which three nominal repeats (denoted as N0, N1, and N2) are configured. Petition 870250089387, dated 10 / 01 / 2025, page 38 / 121 29 / 75

[0168] However, in the case of a real PUSCH repeat, a single PUSCH transmission cannot be transmitted while including a slot limit. That is, if a nominal PUSCH transmission includes a slot limit (e.g., N0, N2 in (a) of Figure 13), two real repeats are executed with the slot limit as the limit, as in (b) of Figure 13. For example, a nominal repeat N0 is executed with two real repeats, such as A0, A1, with the slot limit as the limit.

[0169] Furthermore, a single PUSCH transmission can only be performed using consecutive symbols. If there is an invalid symbol in the time resource where a PUSCH repeat is to be transmitted, the actual repeat will be formed using consecutive symbols with the invalid symbol as the boundary. For example, if symbols #0 to #9 constitute a nominal repeat and symbols #3 to #5 are invalid symbols, symbols #0 to #2 and symbols #6 to #9, excluding the invalid symbol, each constitute an actual repeat.

[0170] Invalid symbols may include the following:

[0171] i) Downlink symbol configured by TDD UL-DL semi-static configuration,

[0172] ii) an invalid symbol pattern set by RRC (which can be set by the invalid symbol pattern indicator),

[0173] iii) SSB symbol configured by SIB1, SSB symbol configured by 'ServngCellConfigCommon',

[0174] iv) Symbol for PDCCH for SIB1,

[0175] v) Invalid symbol for DL-UL switching configured by RRC.

[0176] If a symbol that cannot be used for PUSCH transmission (for example, a DL symbol indicated by the DCI 2_0 format) is included in an actual replay resource, the corresponding actual replay transmission will be discarded and not executed. Petition 870250089387, dated 10 / 01 / 2025, page 39 / 121 30 / 75

[0177] Now, the full duplex operation will be described.

[0178] In 5G, new types of services, such as extended reality (XR), artificial intelligence-based services, and autonomous cars, are emerging. These services have characteristics that dynamically alter traffic in both the downlink (DL) and uplink (UL), and require low latency for traffic (e.g., packets) to be transmitted. In 5G services, traffic will increase exponentially to support these new use cases.

[0179] Existing semi-static or dynamic TDD UL / DL configurations have limitations, such as transmission time delay and carrier interference. The existing FDD method has limitations in terms of efficient use of frequency resources in the DL / UL direction. Therefore, for low latency and efficient resource utilization in NR, the introduction of full duplex operation on a single carrier is being discussed.

[0180] Figure 14 shows examples of how to apply full duplex to an intracarrier.

[0181] With reference to Figure 14, the full duplex method includes sub-band full duplex (hereinafter referred to as sub-band full duplex or SBFD), as shown in (a) of Figure 14, and spectrum-sharing full duplex (hereinafter referred to as SSFD), as shown in (b) of Figure 14.

[0182] In the case of SBFD, DL and UL are transmitted and received through different frequency resources within the same carrier (e.g., carrier #0). That is, different frequency resources are used in DL and UL for the same time resource.

[0183] In the case of SSFD, DL and UL are transmitted and received through the same frequency resources or overlapping frequency resources within the same carrier (e.g., carrier #0). That is, the same frequency resources or overlapping frequency resources can be used in DL and UL for Petition 870250089387, dated 10 / 01 / 2025, page 40 / 121 31 / 75 the same time resource.

[0184] This full duplex (FD) operation can also be used in combination with the existing half duplex (HD) operation. For example, among the time resources used for the existing half-duplex-based TDD operation, some time resources can be used for the full duplex operation. SBFD or SSFD operations can be executed on time resources that perform full duplex operations.

[0185] Figure 15 shows an example in which a time resource operating in half duplex (HD) and a time resource operating in full duplex (FD), such as SBFD or SSFD, coexist.

[0186] In (a) of Figure 15, some time resources operating as SBFD are indicated as SBFD, and time resources operating as HD are indicated as HD. In (b) of Figure 15, some time resources operating as SSFD are indicated as SSFD, and time resources operating as HD are indicated as HD. The time resource unit can be, for example, a slot or symbol.

[0187] In time resources operating as SBFD, some frequency resources are used as DL resources, and other frequency resources are used as UL resources. Between the DL frequency resource and the UL frequency resource, there may be an unused and empty guard sub-band for both DL and UL. Guard sub-bands may also be referred to by other terms, such as guard frequency resources or guard subcarrier(s).

[0188] In time resources operating with SSFD, the entire frequency resource can be used for both DL and UL. Or, to reduce the impact of interference from other adjacent carriers (this may be called ACI (adjacent carrier interference)), some frequency resources at one or both ends of the carrier may not be used for DL ​​and / or UL. That is, one or both ends of the carrier may be used as a band of Petition 870250089387, dated 10 / 01 / 2025, page 41 / 121 32 / 75 guard band not used (sub-guard band) for both DL and UL. Alternatively, to reduce the ACI on UL reception, one or both ends of the carrier can be used only for DL ​​transmission.

[0189] In this description, a slot resource that operates as an HD is referred to as an HD slot, and a slot resource that operates as an SBFD and a slot resource that operates as an SSFD are referred to as an SBFD slot and an SSFD slot, respectively. The SBFD slot and the SSFD slot are also collectively referred to as FD slots.

[0190] In the present description, in time resources operating as FD, among all frequency resources, frequency resources operating as DL may be referred to as DL sub-band, and frequency resources operating as UL may be referred to as UL sub-band, for convenience.

[0191] In the case of full duplex operation, both the base station and the UE can perform full duplex operation. That is, both the base station and the UE can simultaneously perform DL and UL transmission and reception using the same frequency resources or different resources in the same time resource.

[0192] Alternatively, only the base station can perform full duplex operation and the UE can perform half duplex operation. The base station can simultaneously perform DL and UL transmission and reception using the same frequency resources or different resources in the same time resource, but the UE only performs DL reception or UL transmission in a specific time resource. In this case, the base station performs full duplex operation, performing DL transmission and UL reception with different UEs at the same time.

[0193] The content of this description assumes that the base station performs / supports full duplex operation, but the UE performs / supports half duplex operation. However, the content of this description may apply even when both the base station and the UE perform / support full duplex operation. Petition 870250089387, dated 10 / 01 / 2025, page 42 / 121 33 / 75

[0194] Based on this discussion, the present description proposes a method for transmitting PUSCH from an UE when a PUSCH transmission includes SBFD symbols and non-SBFD symbols during intracarrier full duplex operation.

[0195] Hereafter, the term network can be interpreted as gNB or CU / DU. Additionally, the term UE can be interpreted as MT (mobile terminal, mobile termination) of an IAB node or NCR-MT (MT of a network-controlled repeater).

[0196] A. Characteristics of DL / UL time / frequency resources for SBFD and SSFD operation

[0197] A cell (base station) can perform both DL transmission and UL reception on the same time resource in an FD scheme, such as SBFD or SSFD. For example, the base station can perform HD operation on a first time resource and FD operation on a second time resource (which may be a different time resource from the first time resource).

[0198] The first time resource that performs the HD operation performs the DL operation or the UL operation on the frequency resources that span the entire system bandwidth. Within the first time resource that performs the HD operation, the network performs the DL operation through time resource 1-1 and the UL operation through time resource 1-2. At this point, time resources 1-1 and 1-2 do not overlap.

[0199] In the second time resource that executes the FD operation, the network executes DL operations through all or part of the frequency resources (first frequency resources) among the frequency resources that constitute the cell's system BW, and executes UL operations through all or part of the frequency resources (second frequency resources).

[0200] Figure 16 shows examples of a first time feature, a second time feature, a first frequency feature, and a second frequency feature. Petition 870250089387, dated 10 / 01 / 2025, page 43 / 121 34 / 75

[0201] With reference to (a) of Figure 16, in the first time feature (represented by A), the device is operated in HD. In the second time feature (represented by B), for example, the device can be operated as SBFD. In the first time feature, the feature indicated by DL corresponds to time feature 1-1 described above, and the feature indicated by UL corresponds to time feature 1-2 described above.

[0202] With reference to (b) of Figure 16, in the second time feature, the frequency feature operating as DL corresponds to the first frequency feature described above, and the frequency feature operating as UL corresponds to the second frequency feature described above.

[0203] Figure 17 shows another example of a first time feature, a second time feature, a first frequency feature, and a second frequency feature.

[0204] With reference to (a) of Figure 17, in the first time feature (denoted A), the device operates as a half duplex. In the second time feature (denoted B), the device can operate, for example, as an SSFD. In the first time feature, the feature denoted DL corresponds to the first time feature described above, and the feature denoted UL corresponds to the second time feature described above.

[0205] With reference to (b) of Figure 17, in the second time feature, the frequency features operating as DL and DL+UL correspond to the first frequency feature described above, and the frequency features operating as DL+UL correspond to the second frequency feature described above.

[0206] The first frequency feature and / or the second frequency feature may have all or some of the following characteristics.

[0207] 1) When executing the SBFD operation, the first frequency feature and the second frequency feature do not overlap. This ensures that the DL operations Petition 870250089387, dated 10 / 01 / 2025, page 44 / 121 35 / 75 and UL are implemented using different frequency resources. At this point, there may be frequency resources that do not correspond to the first and second frequency resources, and these frequency resources are called guard sub-bands or guard frequency resources. These guard frequency resources may be necessary to reduce interference from DL transmission on UL reception. The guard frequency resource may be located between the first frequency resource and the second frequency resource.

[0208] 2) When performing an SSFD operation, the first frequency resource and the second frequency resource may overlap. At this time, there may be frequency resources that do not correspond to the first and second frequency resources, and these frequency resources are called guard sub-bands or guard frequency resources. These guard frequency resources may be necessary to reduce DL transmission interference on adjacent carriers in UL reception and / or to reduce DL transmission interference on UL reception on adjacent carriers.

[0209] 3) When performing an SBFD operation, the second frequency resource can be composed of contiguous frequency resources, and the first frequency resource can be composed of non-contiguous frequency resources. At this point, the first frequency resource can be composed of a plurality of non-contiguous sets (e.g., two), and each set can be composed of contiguous frequency resources. This aims to reduce DL transmission interference on adjacent carriers in UL resources, placing the second frequency resource used for UL at the center of the frequency resources that constitute the cell. On the other hand, the first frequency resource can be composed of contiguous frequency resources, and the second frequency resource can be composed of non-contiguous frequency resources. At this point, the second frequency resource can be composed of multiple non-contiguous sets (e.g., two), and each Petition 870250089387, dated 10 / 01 / 2025, page 45 / 121 A 36 / 75 array can be composed of contiguous frequency resources. This aims to reduce interference from DL transmission on UL resources in adjacent carriers by positioning the second frequency resource used for DL ​​in the center of the frequency resources that make up the cell.

[0210] 4) When performing the SSFD operation, the second frequency resource may be composed of some frequency resources from the first frequency resource. At this point, the second frequency resource may be configured to have fewer X physical resource blocks (PRBs) on one or both edges of a carrier than the first frequency resource. This aims to reduce DL transmission interference on adjacent carriers in UL reception.

[0211] The network determines the “first time resource” and the “second time resource”, and the “first frequency resource” and the “second frequency resource”, as described above, and provides all or part of the corresponding information to the UE.

[0212] For FD (SBFD and / or SSFD) operation of the cell, the UE can determine information about the time resources (hereinafter referred to as SBFD symbols) that operate as SBFD (and / or SSFD). For this purpose, information about the SBFD symbol can be set for the UE from the network.

[0213] When a specific time resource is configured as a time resource operating in SBFD (symbol SBFD), both DL and UL resources can exist in that time resource. In this case, if there is no UL signal for the base station to receive in that time resource, the base station can only perform DL transmissions. In SBFD resources, DL transmission only occurs within the DL sub-band. Therefore, even if there is no UL signal transmitted in the UL sub-band, DL transmission can only be performed within the DL sub-band.

[0214] In this case, if the base station has no UL transmissions to receive, even if the specific time feature is a feature determined as Petition 870250089387, dated 10 / 01 / 2025, page 46 / 121 37 / 75 symbol SBFD, it may consider running DL transmissions outside the DL subband as well as within the DL subband to improve the DL transfer rate. That is, it may consider running DL transmissions across the entire band.

[0215] That is, in resources defined as SBFD symbols, fault recovery can be considered for the TDD operation, where the DL or UL operation is performed across the entire band, instead of the SBFD operation in the DL / UL subbands.

[0216] In resources not determined as symbol SBFD, the UE can perform the TDD operation (half duplex operation) like a conventional UE. That is, it can perform only the DL or UL operation using all the frequency resources of the cell.

[0217] A UE can receive information about SBFD symbols from the network. Based on this, it can determine whether a specific symbol is an SBFD symbol or a non-SBFD symbol.

[0218] i) If the UE determines that a specific symbol is a non-SBFD symbol, it may perform a legacy operation on the symbol (or determine that a legacy operation must be performed).

[0219] ii) If the UE determines that a specific symbol is an SBFD symbol, it determines that the symbol is a symbol that can perform the SBFD operation from the perspective of the cell.

[0220] The UE may not receive configuration information for SBFD symbols from the network. In this case, i) the UE may determine all symbols as non-SBFD symbols. Therefore, the UE may operate as in legacy TDD for all symbols.

[0221] Or ii) if the UE does not receive configuration information for SBFD symbols from the network, the UE may determine all symbols as SBFD symbols.

[0222] If the EU determines that a specific symbol is an SBFD symbol, i) Petition 870250089387, dated 10 / 01 / 2025, page 47 / 121 38 / 75 In general, the UE can perform DL reception within the DL sub-band and UL transmission within the UL sub-band during the time feature in which the cell is determined to operate in SBFD. ii) Additionally, the base station may consider performing only DL transmission or UL reception during the time feature in which the cell is determined to operate in SBFD, or perform DL transmission or UL reception across the entire band (capable of receiving DL or UL scheduling), as needed.

[0223] The UE can determine the UL sub-band and DL sub-band based on network settings.

[0224] i) The UE receives information about the UL sub-bands and the DL sub-bands from the network and can determine the frequency resources that constitute the UL sub-bands and the DL sub-bands from that.

[0225] ii) Alternatively, the UE can receive only information about the UL sub-band from the network and determine the frequency resources that constitute the UL sub-band from it. In this case, within the frequency resources that constitute the system BW, the remaining frequency resources, excluding the frequency resources defined / determined as UL sub-bands, can be determined as DL sub-bands. Furthermore, if the UE is configured with frequency resources that constitute a guard sub-band, the remaining frequency resources, excluding the frequency resources configured / determined as UL sub-bands and guard sub-bands, within the frequency resources that constitute the system BW, can be determined as DL sub-bands.

[0226] iii) Alternatively, the UE can receive only information about the DL sub-band from the network and determine the frequency resources that constitute the UL sub-band from it. In this case, within the frequency resources that constitute the system BW, the remaining frequency resources, excluding the frequency resources defined / determined as DL sub-bands, can be determined as UL sub-bands. Furthermore, if the UE is configured with resources Petition 870250089387, dated 10 / 01 / 2025, page 48 / 121 39 / 75 frequencies that constitute a guard sub-band, the remaining frequency resources, excluding frequency resources configured / determined as DL sub-bands and guard sub-bands, within the frequency resources that constitute the system BW, may be determined as UL sub-bands.

[0227] In the present description, the time resource operating in SBFD or the symbol SBFD may refer to the “second time resource” mentioned earlier. Additionally, the time resource operating in TDD, the time resource operating in HD, the symbol TDD or the symbol HD in the present description may refer to the “first time resource” mentioned earlier.

[0228] The DL sub-band mentioned in this description may refer to the “first frequency feature” mentioned earlier. Additionally, the UL sub-band mentioned in this description may refer to the “second frequency feature” mentioned earlier.

[0229] Based on the above, the present description describes a method of PUSCH transmission from a UE when a PUSCH transmission includes SBFD symbols and non-SBFD symbols during intracarrier full duplex operation.

[0230] Although the content of this description is described assuming PUSCH transmission (including TBoMS), the content of this description may also be applied to PDSCH reception and PUCCH transmission.

[0231] This description assumes SBFD operation, where a cell performs DL and UL simultaneously using different frequency resources (sub-bands) within the same time resource. However, the content of this description can also be applied to a cell performing SSFD operation.

[0232] Figure 18 illustrates a case where the symbol resources allocated for PUSCH transmission within a slot include SBFD symbols and non-SBFD symbols.

[0233] With reference to Figure 18, in the case of PUSCH type A and / or repetition Petition 870250089387, dated 10 / 01 / 2025, page 49 / 121 40 / 75 TBoMS transmission, the PUSCH / TBoMS transmission within a slot consists of consecutive symbol resources within the slot.

[0234] When non-SBFD symbols and SBFD symbols can exist in the symbols within a slot, the symbol resources allocated for PUSCH transmission (including TBoMS) within the slot can include SBFD symbols and non-SBFD symbols, as shown in Figure 18.

[0235] For type B PUSCH repetition, a nominal repetition consists of consecutive symbol features within one slot or within two adjacent slots. If a nominal repetition includes a slot boundary, the actual repetition is divided by the slot boundary. Therefore, an actual repetition consists of consecutive symbol features within one slot.

[0236] Figure 19 illustrates a case where the symbol resources allocated for PUSCH transmission in multiple slots include SBFD and non-SBFD symbols.

[0237] With reference to Figure 19, slot #N contains SBFD symbols and non-SBFD symbols. Slot #N+1 contains only SBFD symbols.

[0238] In these cases, there may be instances where the symbol resources allocated / configured for PUSCH transmission include both SBFD and non-SBFD symbols.

[0239] PUSCH transmissions in SBFD symbols and PUSCH transmissions in non-SBFD symbols may not be identical in several respects.

[0240] On an SBFD symbol, if the PRB resources allocated for PUSCH transmission are not all included in the UL sub-band, the number of PRBs used in each PUSCH transmission on the SBFD symbol and in the PUSCH transmission on the non-SBFD symbol may be different.

[0241] If the number of PRBs used in PUSCH transmission on an SBFD symbol is different from that used on a non-SBFD symbol (or there may be other reasons besides the number of PRBs being different), the transmission power Petition 870250089387, dated 10 / 01 / 2025, page 50 / 121 41 / 75 The UL (Tx power) rating for the EU in the SBFD symbol and the non-SBFD symbol may differ.

[0242] From the base station perspective, the antenna / panel / RF (antenna / panel / RF) configuration for UL reception in SBFD symbols and non-SBFD symbols is not the same, therefore the channel, UL reception beam (Rx beam) etc., in the two resources may be different.

[0243] When performing PUSCH transmission using non-SBFD symbols and SBFD symbols on the same transmission occasion, the UE may need to apply different PUSCH transmission methods depending on the symbol type (i.e., whether it is an SBFD symbol or a non-SBFD symbol). And / or the base station may need to apply different PUSCH reception methods depending on the symbol type (SBFD / non-SBFD symbol).

[0244] Therefore, several problems can arise when a UE performs a single PUSCH transmission within a slot using both non-SBFD symbols and SBFD symbols.

[0245] Considering these problems, the present description proposes a method for transmitting PUSCH from a UE when a PUSCH transmission is configured to include SBFD and non-SBFD symbols.

[0246] Although the present description describes a transmission method according to a transmission symbol configuration of a PUSCH transmission (transmission opportunity), it can also be applied when a PUSCH is transmitted repeatedly K times.

[0247] Although the content of this description is described assuming PUSCH transmission (including TBoMS), the content of this description may also apply to PDSCH reception and PUCCH transmission.

[0248] <A. Transmissão de PUSCH / TBoMS dentro de um slot>

[0249] A method for transmitting PUSCH to a UE is proposed when a single PUSCH transmission within a slot includes SBFD symbols and not Petition 870250089387, dated 10 / 01 / 2025, page 51 / 121 42 / 75 SBFD. A single PUSCH transmission within a slot may include a TBoMS transmission within the slot. This section may apply to PUSCH repeat transmissions according to the PUSCH A repeat type.

[0250] When a PUSCH transmission includes SBFD and non-SBFD symbols (if configured to include them), the UE may apply one of the following methods to the PUSCH transmission. Alternatively, the UE may apply different methods depending on the instructions / conditions.

[0251] Method 1. If non-SBFD symbols and SBFD symbols are included in the L symbols (L is a natural number greater than or equal to 2) allocated for PUSCH transmission within a specific slot, the UE does not perform PUSCH transmission in that slot.

[0252] Method 2. If the L symbols allocated in the time domain for PUSCH transmission within a specific slot include non-SBFD symbols and SBFD symbols, and if all PRBs (physical resource blocks) allocated for PUSCH transmission in the frequency domain are included in the PRB resources that constitute the UL sub-band, the UE performs PUSCH transmission using the L symbols in the slot. Otherwise, the UE does not perform PUSCH transmission in the slot.

[0253] Method 3. If the L symbols allocated in the time domain for PUSCH transmission within a specific slot include both non-SBFD and SBFD symbols, the PUSCH transmission is performed using the L symbols in the slot, utilizing the PRB (or RBG) resources included in the UL sub-band between the PRB (or RBG) resources allocated for PUSCH transmission in the frequency domain. That is, the PUSCH transmission is performed using the L symbols in the slot using the PRB (or RBG) resources included in the UL sub-band not only in the SBFD symbol, but also in the non-SBFD symbol.

[0254] Method 4. If the L symbols allocated in the time domain for trans Petition 870250089387, dated 10 / 01 / 2025, page 52 / 121 43 / 75 PUSCH mission within a specific slot includes non-SBFD symbols and SBFD symbols, the UE assumes (or determines) that all L symbols are SBFD symbols and, based on this, executes the PUSCH transmission for the L symbols in the corresponding slot.

[0255] Method 5. The UE can perform PUSCH transmission only using symbol resources with a specific symbol type, as follows.

[0256] 5-1 Operation: If a specific slot contains at least one non-SBFD symbol, the UE does not perform PUSCH transmission in that slot. In this case, if all symbols in the slot consist of SBFD symbols, the UE performs PUSCH transmission in that slot.

[0257] Alternatively, if the symbol resources allocated for PUSCH transmission within a specific slot include at least one non-SBFD symbol, the UE does not perform PUSCH transmission in that slot. In this case, if all symbol resources allocated for PUSCH transmission within a specific slot are composed of SBFD symbols, the UE performs PUSCH transmission in that slot.

[0258] Operation 5-2: If at least one SBFD symbol is included in a specific slot, the UE does not perform a PUSCH transmission in that slot. In this case, if all symbols in the slot are composed of non-SBFD symbols, the UE performs a PUSCH transmission in that slot.

[0259] Alternatively, if the symbol resources allocated for PUSCH transmission within a specific slot include at least one SBFD symbol, the UE does not perform PUSCH transmission in that slot. In this case, if all symbol resources allocated for PUSCH transmission within a specific slot are composed of non-SBFD symbols, the UE performs PUSCH transmission in that slot.

[0260] In this case, the EU can perform operation 5-1 or operation 5-2 of Petition 870250089387, dated 10 / 01 / 2025, page 53 / 121 44 / 75 in accordance with the following criteria / conditions / instructions.

[0261] Option 1. If all symbols within the first slot where PUSCH is indicated for transmission are composed of SBFD symbols, or if all symbols allocated for PUSCH transmission within the first slot where PUSCH is indicated for transmission are composed of SBFD symbols, the UE applies operation 5-1 above. Otherwise, the UE applies operation 5-2 above.

[0262] Option 2. If all symbols within the first slot where PUSCH is indicated for transmission are composed of non-SBFD symbols, or if all symbols allocated for PUSCH transmission within the first slot where PUSCH is indicated for transmission are composed of non-SBFD symbols, the UE applies operation 5-1 above. Otherwise, the UE applies operation 5-2 above.

[0263] Option 3. The UE applies operation 5-1 or operation 5-2 via network instruction. To do so, the UE can receive information about the symbol type (SBFD or non-SBFD symbol) used for the network PUSCH transmission via RRC, MAC-CE, DCI signaling, etc. For example, this can be indicated via PUSCH DCI scheduling.

[0264] At this time, the applicability of Methods 2, 3, and 4 may vary depending on the base station implementation method or the UE transmission method. Considering this, different methods may be applied based on instructions from the base station. For example, Method 3 or Method 1 may be applied based on instructions from the base station. These instructions may be communicated to the UE via RRC signaling, for example.

[0265] For PUSCH transmission in a specific slot, if the PUSCH transmission is not performed by the above operation, the UE may not include the slot that constitutes the PUSCH transmission in the available slots. That is, when the PUSCH is transmitted repeatedly K times, the slot in which the PUSCH is not transmitted for the above reason is not included in the K available slots for which the transmission is performed. Petition 870250089387, dated 10 / 01 / 2025, page 54 / 121 45 / 75 PUSCH is set.

[0266] At this time, if a PUSCH is not transmitted in a specific slot by an SBFD symbol and / or a non-SBFD symbol determined semi-statically by RRC and / or MAC-CE, the slot is not included in the available slots that constitute the PUSCH transmission. On the other hand, for a slot in which a PUSCH is not transmitted in a specific slot by an SBFD symbol and / or a non-SBFD symbol determined by means of a DCI or a DCI that does not schedule a PUSCH, the PUSCH transmission is not executed, but the slot may be included in the available slots that constitute the PUSCH transmission.

[0267] <B. Transmissão de Repetição Nominal / Real de Repetição PUSCH Tipo B>

[0268] For type B PUSCH repeat transmission, a method for transmitting a UE PUSCH is proposed when the symbol resources for a nominal repeat transmission or actual repeat include SBFD symbols and non-SBFD symbols.

[0269] The UE may apply at least one of the following methods to transmit nominal or actual repetitions. Alternatively, the UE may apply different methods depending on the instructions / conditions.

[0270] Method 1. If non-SBFD symbols and SBFD symbols are included in the L (L is a natural number greater than or equal to 2, hereafter the same) symbols that constitute a specific nominal repeat, the UE does not perform the transmission of the corresponding nominal repeat.

[0271] Or, if both non-SBFD symbols and SBFD symbols are included in L' (L' is a natural number less than L, i.e., L' <= L, hereafter the same) symbols that constitute a specific real repetition, the UE does not perform the transmission of the corresponding real repetition.

[0272] Method 2. If the L symbols that constitute a nominal repetition Petition 870250089387, dated 10 / 01 / 2025, p. 55 / 121 46 / 75 specifies that it includes non-SBFD symbols and SBFD symbols, and if all PRBs allocated for PUSCH transmission are included in the PRB resources that constitute the UL sub-band, the UE performs nominal repeat transmission using the L symbols. Otherwise, the UE does not perform nominal repeat transmission.

[0273] Alternatively, if the L' (<= L) symbols that constitute a specific actual repeat include non-SBFD symbols and SBFD symbols, and if all PRBs allocated for PUSCH transmission are included in the PRB resources that constitute the UL sub-band, the UE performs the actual repeat transmission using the L' symbols. Otherwise, the UE does not perform the actual repeat transmission.

[0274] Method 3. If the L symbols that constitute a specific nominal repeat include non-SBFD symbols and SBFD symbols, the nominal repeat transmission is performed using the PRB (or RBG) resources included in the UL sub-band between the PRB (or RBG) resources allocated for PUSCH transmission. That is, the nominal repeat transmission is performed using the L symbols using the PRB (or RBG) resources included in the UL sub-band in both the SBFD symbol and the non-SBFD symbol.

[0275] Or, if both non-SBFD symbols and SBFD symbols are included in the L' (<= L) symbols that constitute a specific real repeat, the transmission of the real repeat is performed using the L' symbols using the PRB (or RBG) resources included in the UL sub-band between the PRB (or RBG) resources allocated for PUSCH transmission. That is, the transmission of the real repeat is performed using the L' symbols, using the PRB (or RBG) resources included in the UL sub-band in both the SBFD symbol and the non-SBFD symbol.

[0276] Method 4. If the L symbols that constitute a specific nominal repetition include non-SBFD symbols and SBFD symbols, the UE assumes (or determines) that all L symbols are SBFD symbols and, based on that, executes the Petition 870250089387, dated 10 / 01 / 2025, p. 56 / 121 47 / 75 transmission of nominal repetition using the L symbols.

[0277] Or, if the L' (<= L) symbols that constitute a specific actual repetition include non-SBFD symbols and SBFD symbols, the UE assumes (or determines) that all L' symbols are SBFD symbols and, based on that, performs the transmission of the actual repetition using the L' symbols.

[0278] Method 5. Method that includes SBFD or non-SBFD symbols in invalid symbols, used to determine the symbol features that constitute the actual repetition. Therefore, these symbols are not included in the symbols that perform the actual repetition.

[0279] At this point, it can be determined whether a symbol among the SBFD symbols or not SBFD is included in the invalid symbol, as follows.

[0280] Alt 1. The UE receives an indication from the base station as to which symbol, an SBFD or non-SBFD symbol, is included in the invalid symbol. This indication may be provided via RRC, MAC-CE and / or DCI signaling.

[0281] Alt 2. According to the symbol type indication for which the PUSCH is transmitted, symbols that are not identical to the type are included in the invalid symbols. For example, an UE may be instructed on the symbol type (SBFD symbol / non-SBFD symbol) of the symbol resources to perform the PUSCH transmission via the DCI PUSCH scheduling from the network. That is, it may be instructed whether to perform the PUSCH transmission assuming an SBFD symbol or a non-SBFD symbol. For example, if the UE is instructed to perform a PUSCH transmission assuming an SBFD symbol, it will determine a non-SBFD symbol as invalid. Conversely, if the UE is instructed to perform a PUSCH transmission assuming a non-SBFD symbol, it will determine an SBFD symbol as invalid.

[0282] Alt 3. If the first symbol among the symbols that constitute a nominal repetition is a non-SBFD symbol, include the SBFD symbol among the symbols Petition 870250089387, dated 10 / 01 / 2025, page 57 / 121 48 / 75 invalid. Additionally, if the first symbol among the symbols that constitute a nominal repetition is an SBFD symbol, include the non-SBFD symbol among the invalid symbols.

[0283] Alt 4. When the number of repetitions of type B of PUSCH repetition is K, if the first symbol among the symbols that constitute the first nominal repetition is a non-SBFD symbol, the SBFD symbol will be included among the invalid symbols. Additionally, if the first symbol among the symbols that constitute the first nominal repetition is an SBFD symbol, the non-SBFD symbol will be included among the invalid symbols.

[0284] In addition, for a specific nominal repeat, this method can be applied to perform PUSCH transmission in cases where not all PRBs allocated for PUSCH transmission are included in the PRB resources that constitute the UL sub-band.

[0285] Method 6. If the L symbols that constitute a specific nominal repetition include non-SBFD symbols and SBFD symbols, the nominal repetition is segmented into actual repetitions around the boundary of the SBFD and non-SBFD symbol features.

[0286] For example, among the four symbols that constitute the Nominal Rep2 in Figure 19, the first and second symbols are SBFD symbols, and the third and fourth symbols are non-SBFD symbols. In this case, the first and second symbols constitute a real repetition, and the third and fourth symbols constitute another real repetition, based on the boundary between the features of SBFD symbols and the features of non-SBFD symbols. This will be described in detail with reference to Figure 21.

[0287] In addition, for a specific nominal repeat, this method can be applied to perform PUSCH transmission in cases where not all PRBs allocated for PUSCH transmission are included in the PRB resources that constitute the UL sub-band. Petition 870250089387, dated 10 / 01 / 2025, page 58 / 121 49 / 75

[0288] Currently, the applicability of the above method may vary depending on the base station implementation method or the UE transmission method. Considering this, different methods can be applied based on instructions from the base station. For example, Method 3 or Method 1 can be applied based on instructions from the base station. These instructions can be communicated to the UE via RRC signaling, for example.

[0289] Figure 20 illustrates a method of operation of a UE in a wireless communication system.

[0290] With reference to Figure 20, the UE receives information used to configure parameters of an uplink data channel applicable to a specific frequency band (S201).

[0291] The above information may be, for example, a PUSCH-Config information element used to configure UE-specific PUSCH parameters applicable to a specific BWP.

[0292] The UE performs the replay transmission of the uplink data channel based on the information. However, in the replay transmission, if both full-duplex (FD) and half-duplex (HD) time resources are included in the time resources configured for the transmission of a specific uplink data channel, the UE ignores / discards the transmission of the specific uplink data channel (S202). That is, the transmission of the specific uplink data channel is discarded or the transmission of the specific uplink data channel is not performed.

[0293] Depending on the modality, the UE may also receive a repeater type indicator which indicates the type of repeater transmission of the uplink data channel.

[0294] For example, a UE may be supplied with an indicator (e.g., 'pusch-RepTypeIndicatorDCI-0-1', 'pusch-RepTypeIndicatorDCI-0-2') that indicates Petition 870250089387, dated 10 / 01 / 2025, page 59 / 121 50 / 75 is the type of PUSCH repeat transmission via an RRC message / information element ('PUSCH-Config') used to configure UE-specific PUSCH parameters applicable to a specific bandwidth portion (BWP).

[0295] For example, 'pusch-RepTypeIndicatorDCI-0-1' and 'pusch-RepTypeIndicatorDCI-0-2' indicate (inform) respectively whether the UE will follow the PUSCH type A replay operation or the PUSCH type B replay operation for scheduled PUSCH by DCI 0_1 format, DCI 0_2 format and / or configured grant transmission (CG) associated with the activation of DCI 0_1 / 0_2 format. 'pusch-RepTypeIndicatorDCI-0-1' and 'pusch-RepTypeIndicatorDCI-0-2' activate PUSCH type A replay or PUSCH type B replay, respectively. 'pusch-RepTypeIndicatorDCI-0-1' applies to DCI 0_1 format, and 'pusch-RepTypeIndicatorDCI-0-2' applies to DCI 0_2 format.

[0296] The UE can determine the type of uplink data channel repeat transmission as either first repeat type or second repeat type based on the repeat type indicator.

[0297] For example, the first type of repeater can be a type A shared physical uplink channel repeater (PUSCH), which is configured to perform repeat transmission of the uplink data channel with the same transmission start symbol and transmission symbol length in each slot. A type A PUSCH repeater can only include one PUSCH repeater in a slot.

[0298] And the second type of repetition can be PUSCH type B repetition, which is configured to perform the retransmission of the uplink data channel in transmission symbol length units. In PUSCH type B repetition, multiple PUSCH repetitions can be included in a slot. When repeatedly transmitting a PUSCH with PUSCH type B repetition, if a slot limit or an invalid symbol is included in symbols with the transmission symbol length, two actual retransmissions are performed with the slot limit or the invalid symbol as the limit. Petition 870250089387, dated 10 / 01 / 2025, pp. 60 / 121 51 / 75

[0299] As for the type A PUSCH repeat and the type B PUSCH repeat, they have already been described above with reference to Figures 12 and 13.

[0300] The UE can perform uplink data channel repeater transmission based on the determined repeater type.

[0301] Currently, if both full duplex (FD) and half duplex (HD) time resources are included in the uplink data channel transmission slot, the uplink data channel transmission operation may be performed differently depending on the type of repetition determined.

[0302] For example, the FD time feature may be an SBFD symbol that allows UE to operate in SBFD (full duplex in sub-band), and the HD time feature may be a non-SBFD symbol.

[0303] More specifically, when repeatedly transmitting the uplink data channel (PUSCH) with the first type of repetition (type A PUSCH repetition), if both the FD timing feature and the HD timing feature are included for the transmission of the uplink data channel within a specific slot, the transmission of the uplink data channel may not be performed in the specific slot.

[0304] That is, as illustrated in Figure 18, there may be cases where non-SBFD symbols and SBFD symbols exist in a specific slot, and the symbol resources allocated / configured for PUSCH repeat transmission (including TBoMS) include both SBFD symbols and non-SBFD symbols.

[0305] At this point, if type A PUSCH repeat is defined, PUSCH transmission in the specific slot can be discarded / ignored. According to this method, when executing type A PUSCH repeat, only symbols of the same type exist in each slot where the PUSCH repeat is actually executed. Therefore, the complexity in executing type A PUSCH repeat can be reduced, and a situation where transmission power / transmission / reception beams etc., must be Petition 870250089387, dated 10 / 01 / 2025, page 61 / 121 52 / 75 altered due to a change in the symbol type of each symbol within each slot can be avoided.

[0306] Meanwhile, in the case of repeatedly transmitting an uplink data channel (PUSCH) in the second type of repetition (PUSCH type B repetition), if both the FD time feature and the HD time feature are included for the transmission of the uplink data channel within a specific slot, the uplink data channel can be repeatedly transmitted through different actual transmission features based on the boundary between the FD time feature and the HD time feature.

[0307] This method allows each PUSCH to be transmitted using only symbols of the same symbol type, thus avoiding variations in frequency, transmission power, and transmission beam resources for PUSCH transmission depending on the transmission symbol. Consequently, the complexity of PUSCH transmission can be reduced and the efficiency of PUSCH transmission can be increased.

[0308] In some embodiments, when the time resources that constitute the PUSCH transmission include SBFD symbols and non-SBFD symbols, the PUSCH transmission may or may not be performed depending on the frequency resources allocated for the PUSCH transmission. That is, when the time resources that constitute the PUSCH transmission include SBFD symbols and non-SBFD symbols, whether or not the PUSCH transmission is performed may depend on the frequency resources allocated for the PUSCH transmission.

[0309] For example, if the time resources that constitute the PUSCH transmission include SBFD symbols and non-SBFD symbols, in order for the UE to transmit PUSCH, the frequency resources (e.g., PRB) allocated for PUSCH transmission must not include resources beyond the UL sub-bands.

[0310] That is, when the time resources that constitute the transmission Petition 870250089387, dated 10 / 01 / 2025, page 62 / 121 53 / 75 of PUSCH include SBFD symbols and non-SBFD symbols, i) if the PRB resources allocated for PUSCH transmission include resources beyond the UL sub-band, the UE does not transmit PUSCH, and ii) if all PRB resources allocated for PUSCH transmission are included in the UL sub-band, the UE can transmit PUSCH.

[0311] Figure 21 illustrates a PUSCH repeat transmission method where a PUSCH is transmitted repeatedly with type B PUSCH repeat and different symbol types (SBFD symbols and non-SBFD symbols) are included in a specific slot.

[0312] As illustrated in Figure 21, slot #N includes both SBFD and non-SBFD symbols, and slot #N+1 includes only SBFD symbols. In this case, there may be an instance where the symbol resources allocated / configured for PUSCH transmission include both SBFD and non-SBFD symbols.

[0313] In Figure 21, among the four symbols that constitute the Nominal Rep2, the first and second symbols are SBFD symbols, and the third and fourth symbols are non-SBFD symbols. In this case, the first and second symbols constitute a real repetition based on the boundary between the SBFD symbol feature and the non-SBFD symbol feature, and the third and fourth symbols constitute another real repetition. That is, in the four symbols that constitute the Nominal Rep2, the uplink data channel is transmitted repeatedly through different real transmission features based on the boundary between the FD time feature (SBFD symbol) and the HD time feature (non-SBFD symbol).

[0314] Next, two actual repeat transmissions are performed based on the slot limit.

[0315] Therefore, when the B-type PUSCH repetition is configured, the four nominal repetitions (nominal repetition 0 to nominal repetition 3) of Figure 21 can be executed with a total of five actual repetitions in slot #N and one actual repetition in slot #N+1. Petition 870250089387, dated 10 / 01 / 2025, page 63 / 121 54 / 75

[0316] This method ensures that all symbols in each real repetition have the same symbol type. That is, all symbols in each real repetition are either SBFD symbols or non-SBFD symbols. Therefore, there is an advantage as there is no need to change the transmission power or the transmit / receive beams for each symbol in a real repetition transmission.

[0317] Figure 22 illustrates a signaling process and a method of operation between a base station and a UE.

[0318] With reference to Figure 22, the base station provides TDD configuration information to the UE (S221).

[0319] The TDD configuration information is an example of information for configuring the HD timing features and HD frequency features described above.

[0320] The base station provides FD resource information to the UE (S222). FD resource information may be information that informs the UE about FD time resources and / or FD frequency resources.

[0321] The base station provides a repeater type indicator to the UE (S223).

[0322] For example, the base station may provide an indicator (e.g., 'pusch-RepTypeIndicatorDCI-0-1', 'pusch-RepTypeIndicatorDCI-0-2') that indicates the type of PUSCH repeat transmission via an RRC message / information element ('PUSCH-Config') used to configure UE-specific PUSCH parameters applicable to a specific bandwidth portion (BWP).

[0323] The UE determines the type of repeat (S224). For example, the UE may determine the type of PUSCH repeat transmission as PUSCH repeat type A or PUSCH repeat type B based on the repeat type indicator.

[0324] When both FD time resources and HD time resources are included in a slot for transmitting an uplink data channel, the UE Petition 870250089387, dated 10 / 01 / 2025, page 64 / 121 55 / 75 performs uplink data channel transmission operations differently, according to the type of repetition determined (and / or depending on whether the frequency resources defined for uplink data channel transmission are all included in the UL sub-band) (S225). The frequency resources configured for uplink data channel transmission can be dynamically defined by the DCI.

[0325] The specific operation is described in detail with reference to Figures 18 to 21.

[0326] Figure 23 illustrates a wireless device applicable to this descriptive report.

In this descriptive report, the wireless device can represent a communication modem / circuit / chip.Processor 102 receives information used to configure parameters of an uplink data channel applicable to a specific frequency band and performs a repeat transmission of the uplink data channel based on this information. In the repeat transmission, if the timing resources defined for the transmission of a specific uplink data channel include both a full-duplex (FD) timing resource and a half-duplex (HD) timing resource, the transmission of the specific uplink data channel will be skipped / discarded, or the transmission of the specific uplink data channel will be skipped / discarded depending on the frequency resources defined for the transmission of the specific uplink data channel. The specific operation has been described with reference to Figures 18 to 21.

For example, processor 202 can process information within memory 204 to generate a third piece of information / signal and then transmit radio signals, including the third piece of information / signal, through transceiver 206. Additionally, processor 202 can receive radio signals, including a fourth piece of information / signal, through transceiver 206 and then store the information obtained from processing the fourth piece of information / signal in memory 204.

In the repeat reception, if both full-duplex (FD) and half-duplex (HD) time resources are included in the time resources for receiving a specific uplink data channel, the reception of the specific uplink data channel will be skipped / discarded, or the reception of the data channel will be discarded. Petition 870250089387, dated 10 / 01 / 2025, page 67 / 121 The specific 58 / 75 uplink will be ignored / discarded depending on the frequency resources defined for receiving the specific uplink data channel. The specific operation has been described with reference to Figures 18 to 21.

[0330] The hardware elements of the 100 and 200 wireless devices will be described in more detail below. One or more protocol layers may be implemented, without limitation, by one or more 102 and 202 processors. For example, one or more 102 and 202 processors may implement one or more layers (e.g., functional layers such as PHY, MAC, RLC, PDCP, RRC, and SDAP).

Furthermore, one or more 104 and 204 memories may be connected to one or more 102 and 202 processors by means of various technologies, such as wired or wireless connection.

[0335] One or more 106 and 206 transceivers may transmit user data, control information, and / or radio signals / channels, as mentioned in the operating methods and / or flowcharts of this document, to one or more other devices. One or more 106 and 206 transceivers may receive user data, control information, and / or radio signals / channels, as mentioned in the descriptions, functions, procedures, proposals, operating methods, and / or flowcharts described in this document, from one or more other devices.

For example, one or more 102 and 202 processors may perform the control so that one or more 106 and 206 transceivers may transmit user data, control information, or radio signals to one or more other devices. In addition, one or more 102 and 202 processors Petition 870250089387, dated 10 / 01 / 2025, pp. 70 / 121 61 / 75 can perform the control so that one or more 106 and 206 transceivers can receive user data, control information, or radio signals from one or more other devices. Furthermore, one or more 106 and 206 transceivers can be connected to one or more 108 and 208 antennas, and one or more 106 and 206 transceivers can be configured to transmit and receive user data, control information, and / or radio signals / channels, mentioned in the descriptions, functions, procedures, proposals, methods, and / or operating flowcharts described in this document, through one or more 108 and 208 antennas.

One or more 106 and 206 transceivers can convert the user data, control information, radio signals / channels, etc., processed using one or more 102 and 202 processors, from baseband signals to RF band signals. To this end, one or more 106 and 206 transceivers may include oscillators and / or (analog) filters.

[0336] Figure 24 shows an example of the structure of a signal processing module. Here, signal processing can be performed on processors 102 and 202 of Figure 23.

[0337] With reference to Figure 24, the transmission device (for example, a processor, the processor and a memory, or the processor and a transceiver) in a UE or BS may include a scrambler 301, a modulator 302, a layer mapper 303, an antenna port mapper 304, a feature block mapper 305, and a signal generator 306.

[0338] The transmission device can transmit one or more words. Petition 870250089387, dated 10 / 01 / 2025, pp. 71 / 121 62 / 75 code. The bits encoded in each codeword are scrambled by the corresponding 301 scrambler and transmitted over a physical channel. A codeword can be called a data sequence and can be equivalent to a transport block, which is a data block provided by the MAC layer.

[0339] The scrambled bits are modulated into complex-valued modulation symbols by the corresponding modulator 302. The modulator 302 can modulate the scrambled bits according to a modulation scheme to arrange complex-valued modulation symbols representing positions in a signal constellation. The modulation scheme is not limited and m-PSK (m-Phase Shift Keying) or m-QAM (m-Quadrature Amplitude Modulation) can be used to modulate the encoded data. The modulator can be called a modulation mapper.

[0340] Complex value modulation symbols can be mapped to one or more transport layers by layer mapper 303. Complex value modulation symbols in each layer can be mapped by antenna port mapper 304 for transmission on an antenna port.

[0341] Each 305 resource block mapper can map complex-value modulation symbols relative to each antenna port to appropriate resource elements in a virtual resource block allocated for transmission. The resource block mapper can map the virtual resource block to a physical resource block according to an appropriate mapping scheme. The 305 resource block mapper can allocate complex-value modulation symbols relative to each antenna port to appropriate subcarriers and multiplex the complex-value modulation symbols according to the user.

[0342] The 306 signal generator can modulate complex-value modulation symbols in relation to each antenna port, i.e., antenna-specific symbols. Petition 870250089387, dated 10 / 01 / 2025, pp. 72 / 121 63 / 75 antenna, according to a specific modulation scheme, for example, OFDM (Orthogonal Frequency Division Multiplexing), to generate a complex-valued OFDM symbol signal in the time domain. The signal generator can perform IFFT (Inverse Fast Fourier Transform) on the antenna-specific symbols, and a Cyclic Prefix (CP) can be inserted into the time-domain symbols on which the IFFT was performed. The OFDM symbols undergo digital-to-analog conversion and frequency upconversion, and are then transmitted to the receiving device via each transmitting antenna. The signal generator may include an IFFT module, a CP insertion unit, a digital-to-analog converter (DAC), and a frequency upconverter.

[0343] Figure 25 shows another example of the structure of a signal processing module in a transmission device. In this case, signal processing can be performed on a UE / BS processor, such as processors 102 and 202 in Figure 23.

[0344] With reference to Figure 25, the transmission device (for example, a processor, the processor and a memory, or the processor and a transceiver) in the UE or BS may include a scrambler 401, a modulator 402, a layer mapper 403, a pre-encoder 404, a feature block mapper 405 and a signal generator 406.

[0345] The transmission device can scramble encoded bits into a codeword using the corresponding 401 scrambler and then transmit the scrambled encoded bits through a physical channel.

[0346] The scrambled bits are modulated into complex-valued modulation symbols by the corresponding modulator 402. The modulator can modulate the scrambled bits according to a predetermined modulation scheme to arrange complex-valued modulation symbols representing positions in a signal constellation. The modulation scheme is not limited and pi / 2-BPSK (Pi / 2 Petition 870250089387, 01 / 10 / 2025, p. 73 / 121 64 / 75 Binary Phase Shift Keying (m-PSK) or m-QAM (m-Quadrature Amplitude Modulation) can be used to modulate the encoded data.

[0347] Complex value modulation symbols can be mapped to one or more transport layers by the 403 layer mapper.

[0348] Complex-valued modulation symbols in each layer can be pre-coded by the 404 pre-encoder for transmission on an antenna port. Here, the pre-encoder can perform transform pre-coding on the complex-valued modulation symbols and then perform pre-coding. Alternatively, the pre-encoder can perform pre-coding without performing transform pre-coding. The 404 pre-encoder can process the complex-valued modulation symbols according to MIMO using multiple transmit antennas to output antenna-specific symbols and distribute them to the corresponding 405 feature block mapper. A z output of the 404 pre-encoder can be obtained by multiplying a y output of the 403 layer mapper by a WN x M pre-coding matrix. Here, N is the number of antenna ports and M is the number of layers.

[0349] Each 405 resource block mapper maps complex-valued modulation symbols relative to each antenna port to appropriate resource elements in a virtual resource block allocated for transmission.

[0350] The 405 resource block mapper can allocate complex value modulation symbols to appropriate subcarriers and multiplex the complex value modulation symbols according to the user.

[0351] The 406 signal generator can modulate complex-valued modulation symbols according to a specific modulation scheme, for example, OFDM, to generate a complex-valued OFDM symbol signal in the time domain. The 406 signal generator can perform IFFT (Inverse Fast Fourier Transform). Petition 870250089387, dated 10 / 01 / 2025, page 74 / 121 65 / 75 in antenna-specific symbols, and a CP (Cyclic Prefix) can be inserted into the time-domain symbols in which the IFFT was performed. The OFDM symbols undergo digital-to-analog conversion and frequency upconversion, and are then transmitted to the receiving device via each transmitting antenna. The 406 signal generator may include an IFFT module, a CP insertion unit, a digital-to-analog converter (DAC), and a frequency upconverter.

[0352] The signal processing procedure of the receiving device may be the inverse of the signal processing procedure of the transmitting device. Specifically, the processor of the transmitting device decodes and demodulates the RF signals received by the transceiver's antenna ports. The receiving device may include a plurality of receiving antennas, and the signals received through the receiving antennas are restored to baseband signals and then multiplexed and demodulated according to MIMO to be restored to a data sequence intended to be transmitted by the transmitting device. The receiving device may include a signal restoration unit that restores the received signals to baseband signals, a multiplexer to combine and multiplex the received signals, and a channel demodulator to demodulate multiplexed signal sequences into corresponding codewords.The signal restoration unit, multiplexer, and channel demodulator can be configured as an integrated module or as independent modules to perform their functions. More specifically, the signal restoration unit may include an analog-to-digital converter (ADC) to convert an analog signal into a digital signal, a CP removal unit that removes a CP from the digital signal, a FET module to apply FFT (Fast Fourier Transform) to the signal from which the CP was removed to output symbols in the frequency domain, and a feature element demapper / equalizer to restore the symbols in the frequency domain. Petition 870250089387, dated 10 / 01 / 2025, pp. 75 / 121 66 / 75 for antenna-specific symbols. The antenna-specific symbols are restored to the transport layers by the multiplexer, and the transport layers are restored by the channel demodulator to codewords intended to be transmitted by the transmitting device.

[0353] Figure 26 illustrates an example of a wireless communication device according to an example implementation of the present description.

[0354] With reference to Figure 26, the wireless communication device, for example, a UE, may include at least one of a processor 2310, such as a digital signal processor (DSP) or a microprocessor, a transceiver 2335, a power management module 2305, an antenna 2340, a battery 2355, a screen 2315, a keyboard 2320, a global positioning system (GPS) chip 2360, a sensor 2365, a memory 2330, a SIM card (subscriber identification module) 2325, a speaker 2345 and a microphone 2350. A plurality of antennas and a plurality of processors may be provided.

[0355] Processor 2310 can implement functions, procedures, and methods described in this description. Processor 2310 in Figure 26 may be processors 102 and 202 in Figure 23.

[0356] Memory 2330 is connected to processor 2310 and stores information related to processor operations. The memory may be located inside or outside the processor and connected to it by various techniques, such as wired and wireless connections. Memory 2330 in Figure 26 may be memories 104 and 204 in Figure 23.

[0357] A user can enter various types of information, such as telephone numbers, using various techniques, such as pressing keys on the 2320 keyboard or activating the sound using the 2350 microphone. The 2310 processor can receive and process user information and perform an appropriate function, such as making a Petition 870250089387, dated 10 / 01 / 2025, page 76 / 121 67 / 75 calls using an entered phone number. In some scenarios, data can be retrieved from SIM card 2325 or memory 2330 to perform the appropriate functions. In some scenarios, processor 2310 can display various types of information and data on screen 2315 for user convenience.

[0358] Transceiver 2335 is connected to processor 2310 and transmits and / or receives RF signals. The processor can control the transceiver to initiate communication or transmit RF signals, including various types of information or data, such as voice communication data. The transceiver includes a transmitter and a receiver for transmitting and receiving RF signals. Antenna 2340 can facilitate the transmission and reception of RF signals. In some implementation examples, when the transceiver receives an RF signal, it can forward and convert the signal into a baseband frequency for processing performed by the processor. The signal can be processed by various techniques, such as conversion into audible or readable information to be emitted by the loudspeaker 2345. The transceiver in Figure 26 may be transceivers 106 and 206 in Figure 29.

[0359] Although not shown in Figure 26, several components, such as a camera and a Universal Serial Bus (USB) port, can be additionally included in the UE. For example, the camera can be connected to the 2310 processor.

[0360] Figure 26 is an example of implementation in relation to the UE, and the implementation examples in this description are not limited to it. The UE does not necessarily include all the components shown in Figure 26. That is, some of the components, for example, the keyboard 2320, the GPS chip 2360, the sensor 2365 and the SIM card 2325, may not be essential components. In that case, they may not be included in the UE.

[0361] Figure 27 shows an example of the 2000 processor. Petition 870250089387, dated 10 / 01 / 2025, page 77 / 121 68 / 75

[0362] With reference to Figure 27, processor 2000 may include a control channel transceiver 2010 and a data channel transceiver 2020. For example, processor 2000 may execute the methods described in Figures 16 to 22 from the UE perspective. Processor 2000 may be an example of processors 102 and 202 of Figure 23.

[0363] Figure 28 shows an example of the 3000 processor.

[0364] With reference to Figure 28, processor 3000 may include a control information / data generation module 3010 and a transmission / reception module 3020. Processor 3000 may execute the methods described in Figures 16 to 22, for example, from the perspective of a base station or network. Processor 3000 may be an example of processors 102 and 202 in Figure 23.

[0365] Figure 29 shows another example of a wireless device.

[0366] With reference to Figure 29, the wireless device may include one or more processors 102 and 202, one or more memories 104 and 204, one or more transceivers 106 and 206 and one or more antennas 108 and 208.

[0367] The example of the wireless device described in Figure 29 is different from the example of the wireless device described in Figure 23, because processors 102 and 202 and memories 104 and 204 are separate in Figure 23, while memories 104 and 204 are included in processors 102 and 202 in the example in Figure 29. That is, the processor and memory can constitute a single chipset.

[0372] Figure 31 shows a portable device to which this descriptive report applies. The portable device may include a smartphone, a smartpad, a wearable device (e.g., a smartwatch or smart glasses), or a portable computer (e.g., a notebook). The portable device may be referred to as a mobile station (MS), user terminal (UT), or mobile subscriber station. Petition 870250089387, dated 10 / 01 / 2025, pp. 80 / 121 71 / 75 (MSS), subscriber station (SS), advanced mobile station (AMS) or wireless terminal (WT).

[0373] With reference to Figure 31, the portable device (100) may include an antenna unit (108), a communication unit (110), a control unit (120), a memory unit (130), a power supply unit (140a), an interface unit (140b) and an input / output unit (140c). The antenna unit (108) may be configured as part of the communication unit (110). Blocks 110 to 130 / 140a to 140c correspond to blocks 110 to 130 / 140 of Figure 30, respectively.

[0374] The communication unit (110) can transmit and receive signals (e.g., data, control signals, etc.) with other wireless devices and base stations. The control unit (120) can control components of the portable device (100) to perform various operations. The control unit (120) may include an AP (Application Processor).

[0376] Figure 32 illustrates a communication system 1 applied to this descriptive report.

[0377] With reference to Figure 32, a communication system 1 applied to this descriptive report includes wireless devices, Base Stations (BSs), and a network. In this document, wireless devices represent devices that perform communication using Radio Access Technology (RAT) (e.g., 5G New RAT (NR) or Long Term Evolution (LTE)) and may be referred to as communication / radio / 5G devices. Wireless devices may include, among others, a robot 100a, vehicles 100b-1 and 100b-2, an Extended Reality (XR) device 100c, a portable device 100d, a household appliance 100e, an Internet of Things (IoT) device 100f, and an Artificial Intelligence (AI) device / server 400. For example, vehicles may include a vehicle with wireless communication function, an autonomous vehicle, and a vehicle capable of performing vehicle-to-vehicle communication. In this case, the vehicles may include an Unmanned Aerial Vehicle (UAV) (by Petition 870250089387, dated 10 / 01 / 2025, p. 82 / 121 73 / 75 example, a drone). The XR device may include an Augmented Reality (AR) / Virtual Reality (VR) / Mixed Reality (MR) device and may be implemented in the form of a Virtual Reality Headset (HMD), a Head-Up Display (HUD) mounted in a vehicle, a television, a smartphone, a computer, a wearable device, a home appliance, digital signage, a vehicle, a robot, etc. The wearable device may include a smartphone, a smartpad, a wearable device (e.g., a smartwatch or smart glasses), and a computer (e.g., a notebook). The home appliance may include a TV, a refrigerator, and a washing machine. The IoT device may include a sensor and a smart meter. For example, BSs and the network may be implemented as wireless devices, and a specific wireless device 200a may operate as a BS / network node in relation to other wireless devices.

[0378] Wireless devices 100a to 100f can be connected to network 300 via BSs 200. An AI technology can be applied to wireless devices 100a to 100f, and wireless devices 100a to 100f can be connected to AI server 400 via network 300. Network 300 can be configured using a 3G network, a 4G network (e.g., LTE), or a 5G network (e.g., NR). Although wireless devices 100a to 100f can communicate with each other via BSs 200 / network 300, wireless devices 100a to 100f can perform direct communication (e.g., sidelink communication) between themselves without going through the BSs / network. For example, vehicles 100b-1 and 100b-2 can perform direct communication (e.g., vehicle-to-vehicle (V2V) / vehicle-to-everything (V2X) communication). Additionally, the IoT device (e.g., a sensor) can perform direct communication with other IoT devices (e.g., sensors) or other wireless devices 100a to 100f.

[0379] Wireless communications / connections 150a, 150b, or 150c can be established between wireless devices 100a to 100f / BS 200, or BS 200 / BS 200. Here, wireless communications / connections can be established through various Petition 870250089387, dated 10 / 01 / 2025, page 83 / 121 74 / 75 RATs (e.g., 5G NR), such as 150a uplink / downlink communication, 150b sidelink communication (or D2D communication), or communication between BSs (e.g., relay, Integrated Access and Backhaul (IAB)). Wireless devices and BSs / wireless devices can transmit / receive radio signals between them via 150a and 150b wireless communications / connections. For example, 150a and 150b wireless communications / connections can transmit / receive signals via multiple physical channels. To this end, at least part of several configuration information setup processes, several signal processing processes (e.g., channel encoding / decoding, modulation / demodulation, and resource mapping / demapping), and resource allocation processes for radio signal transmission / reception can be performed based on the various proposals in this description.

[0380] Meanwhile, NR supports multiple numerologies (or subcarrier spacing (SCS)) to support various 5G services. For example, if the SCS is 15 kHz, a wide area of ​​conventional cellular bands can be supported. If the SCS is 30 kHz / 60 kHz, a densely urban bandwidth with lower latency and higher carrier bandwidth is supported. If the SCS is 60 kHz or higher, a bandwidth greater than 24.25 GHz is used to overcome phase noise.

[0381] An NR frequency band can be defined as a frequency band of two types (FR1, FR2). The frequency band values ​​can be changed. For example, the frequency band of the two types (FR1, FR2) can be as shown below in Table 5. For ease of explanation, among the frequency bands used in an NR system, FR1 can mean a “band below 6 GHz” and FR2 can mean a “band above 6 GHz”, and can also be called millimeter waves (mmW).

[0382] [Table 5] Petition 870250089387, dated 10 / 01 / 2025, page 84 / 121 75 / 75 Frequency Band Designation | Corresponding Frequency Band | Subcarrier Spacing (SCS) | FR1 | 450MHz - 6000MHz | 15, 30, 60kHz | FR2 | 24250MHz - 52600MHz | 60, 120, 240kHz

[0383] As described above, the frequency band values ​​in the NR system can be changed. For example, as shown in Table 6 below, FR1 may include a band in the range of 410 MHz to 7125 MHz. That is, FR1 may include a frequency band of at least 6 GHz (or 5850, 5900, 5925 MHz and so on). For example, a frequency band of at least 6 GHz (or 5850, 5900, 5925 MHz and so on) included in FR1 may include an unlicensed band. The unlicensed band may be used for various purposes, for example, the unlicensed band for specific vehicle communication (e.g., automated driving). [Table 6] Frequency Band Designation | Corresponding Frequency Band | Subcarrier Spacing (SCS) | FR1 410MHz-7125MHz | 15, 30, 60kHz | FR2 24250MHz - 52600MHz | 60, 120, 240kHz

[0384] The claims described in this descriptive report can be combined in various ways. For example, technical features in method claims of this descriptive report can be combined to be implemented or executed in an apparatus, and technical features in apparatus claims of this descriptive report can be combined to be implemented or executed in a method. Furthermore, technical features in method claims and apparatus claims of this descriptive report can be combined to be implemented or executed in an apparatus.
