Abstract

A method of operating an apparatus in a wireless communication system and an apparatus using the same are provided. The method involves: receiving information for configuring parameters of an uplink data channel applicable to a specific frequency band; and performing repeated transmission of the uplink data channel based on the information. In the repeated transmission, when both a full duplex (FD) time resource and a half duplex (HD) time resource are included among time resources configured for transmitting a specific uplink data channel, transmission of the specific uplink data channel is skipped.

Description

Technical Field

[0001] This disclosure relates to a method for operating a device in a wireless communication system and an apparatus for using the method. Background Technology

[0002] With an increasing number of communication devices requiring greater communication capacity, there is a need for improved mobile broadband communications compared to existing radio access technologies. Furthermore, massive machine-type communication (MTC) providing various services by connecting numerous devices and multiple objects is also one of the main issues to be considered in next-generation communications. Additionally, communication system designs considering reliability / latency-sensitive services / UEs are being discussed. The introduction of next-generation radio access technologies considering enhanced mobile broadband communication (eMBB), massive machine-type communication (mMTC), and ultra-reliable low latency communication (URLLC) is being discussed. In this disclosure, for convenience, such new technologies may be referred to as new radio access technologies (new RAT or NR).

[0003] In NR or post-NR wireless communication systems, full-duplex (FD) operation can be performed. When FD operation is performed, downlink reception and uplink transmission can occur simultaneously within a given time resource. Half-duplex (HD) operation differs in that only one of downlink reception or uplink transmission can be performed within a given time resource. For FD operation, i) some frequency resources within the same time resource can be allocated as downlink subbands and others as uplink subbands (this can be called subband FD or SBFD (subband full-duplex)), or ii) frequency resources within the same time resource can be allocated for both downlink reception and uplink transmission (this can be called spectrum-sharing FD or SSFD (spectrum-sharing full-duplex)).

[0004] Within a specific time slot, SBFD symbols operating under SBFD and non-SBFD symbols can coexist. In this case, resources for uplink data channel transmission can be configured / allocated to include both SBFD and non-SBFD symbols. However, since each symbol may differ in transmittable frequency resources, transmit power, and transmit beam, problems may arise when the User Equipment (UE) transmits uplink data channels using both SBFD and non-SBFD symbols. Summary of the Invention

[0005] Technical issues

[0006] The technical problem to be solved by this disclosure is to provide a method for operating a device in a wireless communication system and an apparatus for using the method.

[0007] Technical solution

[0008] A method for operating a device in a wireless communication system and an apparatus using the method are provided. According to the method, a user equipment (UE) receives information for configuring parameters for an uplink data channel suitable for a specific frequency band, and performs repeated transmission of the uplink data channel based on the information. In the repeated transmission, transmission of the specific uplink data channel is skipped based on both full-duplex (FD) time resources and half-duplex (HD) time resources being included in the time resources configured for transmission of the specific uplink data channel.

[0009] In another aspect, a UE, a device, and a computer-readable medium for performing the above-described methods are provided.

[0010] On the other hand, a method for operating a base station and a base station using the method are provided. According to the base station operation method, the base station sends information to a user equipment (UE) for configuring parameters for an uplink data channel applicable to a specific frequency band, and performs repeated reception of the uplink data channel based on this information. In repeated reception, reception of the specific uplink data channel is skipped based on both full-duplex (FD) time resources and half-duplex (HD) time resources being included in the time resources configured for reception of the specific uplink data channel.

[0011] Beneficial effects

[0012] According to the method disclosed herein, by transmitting each PUSCH using only symbols of the same symbol type, it is possible to prevent changes in frequency resources, transmission power, transmission beam, etc., for PUSCH transmission based on the transmitted symbols.

[0013] It can reduce the complexity of PUSCH transmission and also improve the efficiency of PUSCH transmission. Attached Figure Description

[0046] In this specification, “A or B” may mean “A only”, “B only”, or “both A and B”. In other words, in this specification, “A or B” may be interpreted as “A and / or B”. For example, in this specification, “A, B or C” may mean “A only”, “B only”, “C only”, or “any combination of A, B, and C”.

[0047] The forward slash ( / ) or comma used in this specification can mean "and / or". For example, "A / B" can mean "A and / or B". Therefore, "A / B" can mean "A only", "B only", or "both A and B". For example, "A, B, C" can mean "A, B, or C".

[0048] In this specification, "at least one of A and B" may mean "only A", "only B" or "both A and B". Additionally, in this specification, 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".

[0049] Additionally, in this specification, "at least one of A, B, and C" may mean "A only", "B only", "C only" 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".

[0050] Additionally, the parentheses used in this specification may mean "for example". Specifically, when indicated as "Control Message (PDCCH)", this may mean that "PDCCH" is cited as an example of "control message". In other words, "control message" in this specification is not limited to "PDCCH", and "PDDCH" may be cited as an example of "control message". Specifically, when indicated as "Control Message (i.e., PDCCH)", this may also mean that "PDCCH" is cited as an example of "control message".

[0051] The technical features described individually in one of the accompanying drawings in this specification can be implemented individually or simultaneously.

[0052] Figure 1 This illustrates a wireless communication system to which this disclosure can be applied. This may also be referred to as an E-UTRAN (Evolved UMTS Terrestrial Radio Access Network) or an LTE (Long Term Evolution) / LTE-A system.

[0053] E-UTRAN includes a base station (BS) 20, which provides the control plane and user plane to the user equipment (UE) 10. The UE 10 can be fixed or mobile and can be referred to by other terms such as mobile station (MS), user terminal (UT), subscriber station (SS), mobile terminal (MT), radio device, terminal, etc. The BS 20 is generally a fixed station that communicates with the UE 10 and can be referred to by other terms such as evolved Node B (eNB), base transceiver system (BTS), access point, etc.

[0054] The BSs interconnect via the X2 interface. The BSs also connect to the Evolved Packet Core (EPC) 30 via the S1 interface, and more specifically, to the Mobility Management Entity (MME) via the S1-MME, and to the Serving Gateway (S-GW) via the S1-U.

[0055] EPC 30 includes an MME, an S-GW, and a Packet Data Network Gateway (P-GW). The MME contains UE access information or UE capability information, which is generally used for UE mobility management. The S-GW is a gateway with E-UTRAN as its endpoint. The P-GW is a gateway with PDN as its endpoint.

[0056] The radio interface protocol layer between the UE and the network can be divided into three layers—Layer 1 (L1), Layer 2 (L2), and Layer 3—based on the well-known Open Systems Interconnection (OSI) model in communication systems. The Physical Layer (PHY), belonging to Layer 1, provides information transmission services using physical channels. The Radio Resource Control (RRC) layer, belonging to Layer 3, controls radio resources between the UE and the network; therefore, the RRC layer exchanges RRC messages between the UE and the BS.

[0057] Figure 2 This is a block diagram illustrating the radio protocol architecture used in the user plane. Figure 3 This is a block diagram illustrating the radio protocol architecture used for the control plane. The user plane is the protocol stack used for user data transmission. The control plane is the protocol stack used for control signal transmission.

[0058] Reference Figure 2 and Figure 3 The PHY layer provides information transmission services to higher layers (i.e., higher-level layers) via physical channels. The PHY layer connects to the Media Access Control (MAC) layer, which is higher up, via transport channels. Data is transmitted between the MAC layer and the PHY layer via transport channels. Transport channels are classified according to how data is transmitted through the radio interface and the characteristics of the data.

[0059] Data moves between different PHY layers (i.e., the transmitter's PHY layer and the receiver's PHY layer) via physical channels. These physical channels can be modulated according to an orthogonal frequency division multiplexing (OFDM) scheme and utilize time and frequency as radio resources.

[0060] The MAC layer's functions include mapping between logical channels and transport channels, as well as multiplexing and demultiplexing into transport blocks provided via physical channels on the transport channels of MAC Service Data Units (SDUs) that belong to the logical channels. The MAC layer provides services to the Radio Link Control (RLC) layer through the logical channels.

[0061] The RLC layer's functions include the concatenation, segmentation, and reassembly of RLC SDUs. To ensure the various types of Quality of Service (QoS) required for radio bearers (RBs), the RLC layer provides three operating modes: Transparent Mode (TM), Unacknowledged Mode (UM), and Acknowledged Mode (AM). AM RLC provides error correction via Automatic Repeat Request (ARQ).

[0062] The RRC layer is defined only on the control plane. The RRC layer is associated with the configuration, reconfiguration, and release of radio bearers, and is responsible for the control of logical channels, transport channels, and PHY channels. RB represents the logical path provided by Layer 1 (PHY layer) and Layer 2 (MAC layer, RLC layer, and PDCP layer) for transmitting data between the UE and the network.

[0063] The Packet Data Convergence Protocol (PDCP) layer on the user plane performs functions including the transmission of user data and header compression and encryption. The PDCP layer on the user plane also performs functions related to the transmission of control plane data and encryption / integrity protection.

[0064] RB configuration refers to defining the characteristics of the radio protocol layer and channel to provide specific services and configuring various detailed parameters and operating methods. RBs can be divided into two types: Signaling RB (SRB) and Data RB (DRB). SRB is used as the channel for sending RRC messages in the control plane, while DRB is used as the channel for sending user data in the user plane.

[0065] If an RRC connection is established between the UE's RRC layer and the E-UTRAN's RRC layer, the UE is in RRC connected state. Otherwise, the UE is in RRC idle state.

[0066] Downlink transport channels used for transmitting data from the network to the UE include a broadcast channel (BCH) for transmitting system information and a downlink shared channel (SCH) for transmitting user service or control messages. Service or control messages for downlink multicast or broadcast services can be transmitted via the downlink SCH, or via a separate downlink multicast channel (MCH). Furthermore, UL transmission channels used for transmitting data from the UE to the network include a random access channel (RACH) for transmitting initial control messages and an uplink shared channel (SCH) for transmitting user service or control messages.

[0067] The logical channels located above the transport channel and mapped to the transport channel include the Broadcast Control Channel (BCCH), Paging Control Channel (PCCH), Common Control Channel (CCCH), Multicast Control Channel (MCCH), and Multicast Service Channel (MTCH).

[0068] A physical channel comprises multiple OFDM symbols in the time domain and multiple subcarriers in the frequency domain. A subframe comprises multiple OFDM symbols in the time domain. A Resource Allocation Unit (RB) is a unit of resource allocation that includes multiple OFDM symbols and multiple subcarriers. Additionally, each subframe may allocate specific subcarriers of a particular OFDM symbol (e.g., the first OFDM symbol) to the Physical Downlink Control Channel (PDCCH), i.e., the L1 / L2 control channel. The Transmission Time Interval (TTI) is the unit of time for subframe transmission.

[0069] The following section will describe the new radio access technology (New RAT, NR).

[0070] With an increasing number of communication devices requiring greater communication capacity, there is a need for improved mobile broadband communications compared to existing radio access technologies. Furthermore, massive machine-type communication (MTC) providing various services by connecting numerous devices and multiple objects is also one of the main issues to be considered in next-generation communications. Additionally, communication system designs considering reliability / latency-sensitive services / UEs are being discussed. The introduction of next-generation radio access technologies considering enhanced mobile broadband communication (eMBB), massive machine-type communication (mMTC), and ultra-reliable low latency communication (URLLC) is being discussed. In this disclosure, for convenience, such new technologies may be referred to as new radio access technologies (new RAT or NR).

[0071] Figure 4 An example of a system architecture for a next-generation radio access network (NG-RAN) using NR is presented.

[0072] Reference Figure 4 NG-RAN may include gNBs and / or eNBs that provide user plane and control plane protocol termination to the UE. Figure 4 This example illustrates the case involving only the gNB. The gNB (eNB) connects via the Xn interface. Both the gNB and eNB connect to the 5G core network (5GC) via the NG interface. More specifically, the gNB and eNB connect to the Access and Mobility Management Function (AMF) via the NG-C interface and to the User Plane Function (UPF) via the NG-U interface.

[0073] Figure 5 This illustrates the functional division between NG-RAN and 5GC.

[0074] Reference Figure 5The gNB can provide functions such as Inter-Cell Radio Resource Management (IRM), Radio Bearer Management (RB) control, Connection Mobility Control, Radio Access Control, Measurement Configuration and Provisioning, and Dynamic Resource Allocation. The AMF can provide functions such as NAS security and Idle State Mobility Processing. The UPF can provide functions such as Mobility Anchoring and PDU Processing. The SMF can provide functions such as UE IP Address Allocation and PDU Session Control.

[0075] Figure 6 An example of a frame structure that can be applied to NR is shown.

[0076] Reference Figure 6 In NR, radio frames (hereinafter also referred to as frames) can be used for both UL transmission and downlink transmission. The frame length is 10ms, which can be defined as two 5ms half-frames (HF). HF can be defined as five 1ms subframes (SF). SF can be divided into one or more time slots, the number of time slots within an SF depending on the subcarrier spacing (SCS). Each time slot includes 12 or 14 OFDM(A) symbols depending on the cyclic prefix (CP). With normal CP, each time slot includes 14 symbols. With extended CP, each time slot includes 12 symbols. Here, symbols can include OFDM symbols (or CP-OFDM symbols) and single-carrier-FDMA (SC-FDMA) symbols (or Discrete Fourier Transform Spread Spectrum-OFDM (DFT-s-OFDM) symbols).

[0077] Table 1 below illustrates the subcarrier spacing configuration μ.

[0078] [Table 1]

[0079]

[0080] Table 2 below illustrates the number of time slots (N) in a frame configured with subcarrier spacing μ. frame,μ slot ), the number of time slots in the subframe (N) subframe,μ slot ), the number of symbols in the time slot (N) slot symb )wait.

[0081] [Table 2]

[0082]

[0083] exist Figure 6 The example shows the cases where μ = 0, 1, 2, and 3.

[0084] Table 2-1 below illustrates how the number of symbols per slot, the number of slots per frame, and the number of slots per subframe vary depending on the SCS when using extended CP.

[0085] [Table 2-1]

[0086] <![CDATA[SCS(15·2 μ )]]> <![CDATA[N slot symb ]]> <![CDATA[N frame,μ slot ]]> <![CDATA[N subframe,μ slot ]]> 60kHz (μ=2) 12 40 4

[0087] In NR systems, OFDM(A) parameter sets (e.g., SCS, CP length, etc.) can be configured differently across multiple cells merged into a single UE. Therefore, the (absolute time) duration of time resources (e.g., SF, time slots, or TTI) consisting of the same number of symbols (collectively referred to as Time Units (TUs) for simplicity) can be configured differently across merged cells.

[0088] Figure 7 The time slot structure is illustrated.

[0089] A time slot can include multiple symbols in the time domain. For example, in the case of normal CP, a time slot can include 14 symbols (or 7 symbols), but in the case of extended CP, a time slot can include 12 symbols (or 6 symbols). A carrier can include multiple subcarriers in the frequency domain. A resource block (RB) can be defined as multiple consecutive subcarriers in the frequency domain (e.g., 12 subcarriers). A bandwidth portion (BWP) can be defined as multiple consecutive (physical) resource blocks (P)RBs in the frequency domain, and a BWP can correspond to a set of parameters (e.g., SCS, CP length, etc.). A carrier can include up to N (e.g., 5) BWPs. Data communication can be performed through active BWPs, and only one BWP can be activated for a UE. In the resource grid, each element can be called a resource element (RE), and a complex symbol can be mapped to an RE.

[0090] The Physical Downlink Control Channel (PDCCH) may include one or more Control Channel Elements (CCEs), as illustrated in Table 3 below.

[0091] [Table 3]

[0092] Aggregation level Number of CCEs 1 1 2 2 4 4 8 8 16 16

[0093] In other words, PDCCH can be transmitted through resources including 1, 2, 4, 8, or 16 CCEs. Here, a CCE includes six Resource Element Groups (REGs), and a REG includes a resource block in the frequency domain and an orthogonal frequency division multiplexing (OFDM) symbol in the time domain.

[0094] The monitoring implies decoding each PDCCH candidate according to the downlink control information (DCI) format. The UE monitors a set of PDCCH candidates in one or more CORESETs (described below) on the active DL BWP of each active serving cell configured with PDCCH monitoring, based on the corresponding search space set.

[0095] In NR, a new unit called the Control Resource Set (CORESET) can be introduced. The UE can receive the PDCCH in the CORESET.

[0096] Figure 8 An example of CORESET is shown.

[0097] Reference Figure 8 CORESET includes N in the frequency domain. CORESET RB N in the resource block and time domain CORESET symb ∈{1, 2, 3} symbols. N can be provided by the base station via higher-layer signaling. CORESET RB and N CORESET symb .like Figure 8 As illustrated, a CORESET may include multiple CCEs (or REGs).

[0098] The UE can attempt to detect PDCCH in units of 1, 2, 4, 8, or 16 CCEs in the CORESET. One or more CCEs that can be attempted for PDCCH detection can be referred to as PDCCH candidates.

[0099] Multiple CORESETs can be configured for a UE.

[0100] The control area of ​​the wireless communication system (e.g., LTE / LTE-A) of the relevant technology is configured on the entire system BW used by the base station (BS). All UEs except for some UEs that only support narrowband (e.g., eMTC / NB-IoT UEs) must be able to receive the radio signals of the entire system BW of the BS in order to properly receive / decode the control information sent by the BS.

[0101] On the other hand, NR introduces the aforementioned CORESET. A CORESET is a radio resource used to transmit control information received by the UE, and it can utilize only a portion of the system bandwidth instead of the entire system bandwidth. The BS can allocate CORESETs to each UE and can transmit control information through the allocated CORESETs. In NR, the UE can receive control information from the BS without having to receive the entire system bandwidth.

[0102] CORESET can include UE-specific CORESET for sending UE-specific control information and public CORESET for sending common control information for all UEs.

[0103] On the other hand, depending on the application domain, NR may require high reliability. In this case, the target block error rate (BLER) of downlink control information (DCI) transmitted via a downlink control channel (e.g., physical downlink control channel (PDCCH)) can be significantly reduced compared to existing technologies. As an example of a method to meet the requirement of high reliability, the amount of content included in the DCI can be reduced and / or the amount of resources used when transmitting the DCI can be increased. In this case, resources may include at least one of resources in the time domain, resources in the frequency domain, resources in the code domain, and resources in the spatial domain.

[0104] The following technologies / features can be applied in NR.

[0105] <Self-contained subframe structure>

[0106] Figure 9 An example of a frame structure for a new radio access technology is shown.

[0107] In NR, such as Figure 9 As shown, the structure in which the control channel and data channel are time-division multiplexed within a TTI can be regarded as a frame structure in order to minimize the waiting time.

[0108] exist Figure 9 In the diagram, the shaded area represents the downlink control area, and the black area represents the uplink control area. Unmarked areas can be used to transmit downlink data (DL data) or uplink data (UL data). This structure is characterized by downlink (DL) transmission and uplink (UL) transmission occurring sequentially within a single subframe. DL data can be sent within a subframe, and UL ACK / NACK (acknowledgment / non-acknowledgment) can also be received. Therefore, the time required to retransmit data when errors occur is reduced, thus minimizing the latency for final data transmission.

[0109] In the subframe structure of data and control TDM, there may be time gaps required for the base station and UE to switch from transmit mode to receive mode or from receive mode to transmit mode. For this reason, some OFDM symbols during the DL to UL handover can be set as guard periods (GP) in the self-contained subframe structure.

[0110] Figure 10 An example of a self-contained time slot structure is shown.

[0111] In an NR system, a timeslot contains DL control channels, DL or UL data, and UL control channels. For example, the first N symbols in a timeslot (hereinafter, the DL control area) can be used to transmit DL control channels, and the last M symbols in the timeslot (hereinafter, the UL control area) can be used to transmit UL control channels. N and M are both integers greater than or equal to 0. The resource area (hereinafter, the data area) located between the DL control area and the UL control area can be used for either DL data transmission or UL data transmission. For example, consider the following configuration. The time slots are listed in chronological order.

[0112] 1. DL configuration only.

[0113] 2. UL configuration only.

[0114] 3. Hybrid UL-DL configuration,

[0115] -DL area + GP (protection period) + UL control area

[0116] -DL control area +GP +UL area.

[0117] DL regions: (i) DL data region, (ii) DL control region + DL data region

[0118] UL area: (i) UL data area, (ii) UL data area + UL control area.

[0119] In the DL control area, the PDCCH can be transmitted, and in the DL data area, the Physical Downlink Shared Channel (PDSCH) can be transmitted. In the UL control area, the Physical Uplink Control Channel (PUCCH) can be transmitted, and in the UL data area, the Physical Uplink Shared Channel (PUSCH) can be transmitted. Downlink control information (DCI), such as DL data scheduling information or UL data scheduling information, can be transmitted on the PDCCH. Uplink control information (UCI), such as ACK / NACK information, Channel State Information (CSI) information, or Scheduling Request (SR) for DL ​​data, can be transmitted on the PUCCH. GP provides time slots during the transition from TX mode to RX mode in the gNB and UE, or during the transition from RX mode to TX mode in the gNB and UE. Some symbols within a subframe during the transition from DL to UL can be configured as GP.

[0120] <Simulated Beamforming #1>

[0121] The wavelength is shortened to millimeter wave (mmW), thus allowing a large number of antenna elements to be installed in the same area. That is, the wavelength is 1 cm at 30 GHz, so a total of 100 antenna elements can be installed in a two-dimensional array in a 5×5 cm panel with a spacing of 0.5λ (wavelength). Therefore, a large number of antenna elements can be used in mmW to increase beamforming (BF) gain, thereby increasing coverage or improving throughput.

[0122] In this scenario, if transceiver units (TXRUs) are provided to adjust the transmit power and phase of each antenna element, independent beamforming for each frequency resource can be performed. However, installing TXRUs for all approximately 100 antenna elements is cost-inefficient. Therefore, a method using analog phase shifters to map a large number of antenna elements to a single TXRU and control the beam direction is considered. This analog beamforming can only form a beam direction across all frequency bands, thus failing to provide frequency-selective beamforming.

[0123] Hybrid beamforming (BF) with B TXRUs (less than Q antenna elements) can be considered an intermediate form between digital BF and analog BF. In this case, the number of beam directions that can be transmitted simultaneously is limited to B, although this number depends on the method of connecting the B TXRUs and Q antenna elements.

[0124] <Simulated Beamforming #2>

[0125] When multiple antennas are used in NR (Radio Frequency I / O), hybrid beamforming, a combination of digital and analog beamforming, emerges. Here, in analog beamforming (or RF beamforming), precoding (or combination) is performed at the RF end, thus achieving performance similar to digital beamforming while reducing the number of RF chains and D / A (or A / D) converters. For ease of description, the hybrid beamforming structure can be represented by N TXRUs and M physical antennas. Then, the digital beamforming of the L data layers transmitted at the transmitter can be represented by an N×L matrix. The converted N digital signals are then converted into analog signals via TXRUs and applied using an analog beamforming matrix represented by an M×N matrix.

[0126] System information for the NR system can be broadcast. In this case, analog beams belonging to different antenna panels can be transmitted simultaneously within a single symbol. A scheme is being discussed to introduce a beam RS (BRS) as a reference signal (RS) transmitted by applying a single analog beam (corresponding to a specific antenna panel) to measure the channel of each analog beam. The BRS can be defined for multiple antenna ports, and each antenna port of the BRS can correspond to a single analog beam. In this case, unlike the BRS, a synchronization signal or xPBCH can be transmitted by applying all analog beams within a group of analog beams so that it can be correctly received by any UE.

[0127] In NR, in the time domain, a synchronization signal block (SSB, or also known as the synchronization signal and physical broadcast channel (SS / PBCH)) can consist of four OFDM symbols indexed in ascending order from 0 to 3 within the synchronization signal block, and the PBCH associated with the primary synchronization signal (PSS), secondary synchronization signal (SSS), and demodulation reference signal (DMRS) can be mapped to symbols. As mentioned above, a synchronization signal block can also be represented by an SS / PBCH block.

[0128] In NR, since multiple synchronization signal blocks (SSBs) can be transmitted at different times and SSBs can be used to perform initial access (IA), serving cell measurements, etc., it is preferable to transmit the SSB first when its transmission time and resources overlap with those of other signals. For this purpose, the network can broadcast the transmission time and resource information of the SSBs or indicate them through UE-specific RRC signaling.

[0129] In NR, beams can be used for both transmitting and receiving. If the receiving performance of the currently serving beam deteriorates, a process called beam fault recovery (BFR) can be performed to search for a new beam.

[0130] Since BFR processing is not intended to declare errors or failures in the link between the network and the UE, it can be assumed that the connection to the current serving cell is maintained even if BFR processing is performed. During BFR processing, measurements of different beams configured by the network (which can be represented by CSI-RS port or Synchronization Signal Block (SSB) index) can be performed, and the optimal beam for the corresponding UE can be selected. The UE can perform BFR processing in a manner that associates RACH processing with the beam that produces good measurement results.

[0131] The Transmit Configuration Indicator (TCI) state will now be described. The TCI state can be configured for each CORESET of the control channel, and the parameters used to determine the RX beam of the UE can be determined based on the TCI state.

[0132] For each DL BWP of the serving cell, the UE can be configured for three or fewer CORESETs. Additionally, the UE can receive the following information for each CORESET.

[0133] 1) CORESET index p (e.g., one of 0 to 11, where the index of each CORESET can be uniquely determined within the BWP of a serving cell),

[0134] 2) PDCCH DM-RS scrambling sequence initialization values,

[0135] 3) The duration of CORESET in the time domain (which can be given in symbolic form).

[0136] 4) Resource block set,

[0137] 5) CCE to REG mapping parameters,

[0138] 6) Antenna port quasi-co-addressing, which indicates the quasi-co-addressing (QCL) information of the DM-RS antenna ports used for receiving PDCCH in each CORESET (from a set of antenna port quasi-co-addressings provided by a higher-layer parameter called "TCI-State").

[0139] 7) Indications regarding the presence of the Transmit Configuration Indicator (TCI) field in a specific DCI format sent by PDCCH in CORESET.

[0140] Quasi-co-located (QCL) will be described. Two antenna ports are said to be quasi-co-located (QCL) if the characteristics of the channel through which a symbol at one antenna port is transmitted can be inferred from the characteristics of the channel through which a symbol at another antenna port is transmitted. For example, when two signals A and B are transmitted from the same transmit antenna array with the same / similar spatial filters, these two signals may experience the same / similar channel states. From the receiver's perspective, upon receiving one of these two signals, the other signal can be detected by using the channel characteristics of the received signal.

[0141] In this sense, when signals A and B are called quasi-co-located (QCL), it can mean that signals A and B experience similar channel conditions. Therefore, the channel information estimated for detecting signal A is also useful for detecting signal B. In this paper, channel conditions can be defined based on, for example, Doppler frequency shift, Doppler spread, average delay, delay spread, and spatial reception parameters.

[0142] The “TCI-State” parameter associates one or two downlink reference signals with the corresponding QCL types (QCL types A, B, C, and D, see Table 4).

[0143] [Table 4]

[0144] QCL type describe QCL-Type A Doppler frequency shift, Doppler spread, average delay, delay spread QCL-Type B Doppler frequency shift, Doppler spread QCL-Type C Doppler shift, average delay QCL-Type D Spatial Rx parameters

[0145] Each “TCI-State” may include parameters for configuring the QCL relationship between one or two downlink reference signals and the DM-RS port of the PDSCH (or PDDCH) or the CSI-RS port of the CSI-RS resource.

[0146] Furthermore, for each DL BWP configured for a UE in a serving cell, the UE may provide 10 (or fewer) search space sets. For each search space set, the UE may provide at least one of the following information.

[0147] 1) Search space set index s (0≤s<40), 2) Correlation between CORESET p and search space set s, 3) PDCCH monitoring periodicity and PDCCH monitoring offset (slot units), 4) PDCCH monitoring pattern within a slot (e.g., indicating the first symbol of CORESET in the slot used for PDCCH monitoring), 5) Number of slots in which search space set s exists, 6) Number of PDCCH candidates per CCE aggregation level, 7) Information indicating whether search space set s is CSS or USS.

[0148] In NR, CORESET#0 can be configured via PBCH (or UE-specific signaling used for handover, PSCell configuration, or BWP configuration). The search space (SS) set #0 configured via PBCH can monitor different offsets (e.g., slot offset, symbol offset) for each associated SSB. This may be necessary to minimize the timing of search space monitoring by the UE. Alternatively, this may be necessary to provide a beam scan control / data area capable of performing control / data transmission on a per-beam basis to persistently perform communication with the UE under optimal beam dynamic changes.

[0149] Figure 11 The physical channel and typical signal transmission are illustrated.

[0150] Reference Figure 11 In a wireless communication system, the UE receives information from the BS via the downlink (DL) and transmits information to the BS via the uplink (UL). The information transmitted / received by the BS and UE includes data and various control information, and various physical channels exist depending on the type / purpose of the information transmitted / received by the BS and UE.

[0151] When a UE is powered on again after a power outage or enters a new cell, it performs an initial cell search operation (S11) such as adjusting synchronization with the BS. For this purpose, the UE receives the primary synchronization channel (PSCH) and secondary synchronization channel (SSCH) from the BS to adjust synchronization with the BS and obtains information such as cell identity (ID). Additionally, the UE can receive the physical broadcast channel (PBCH) from the BS to obtain broadcast information within the cell. Furthermore, the UE can receive a downlink reference signal (DL RS) during the initial cell search step to identify the downlink channel state.

[0152] (Initial) Cell search is the process by which the UE obtains time and frequency synchronization with cells and detects the cell IDs of those cells. Cell search can be based on the cell's primary and secondary synchronization signals, and PBCH DMRS.

[0153] After completing the initial cell search, the UE can receive the Physical Downlink Control Channel (PDCCH) and its corresponding Physical Downlink Shared Channel (PDSCH) to obtain more specific system information (S12).

[0154] Subsequently, the UE can perform a random access procedure to complete access to the BS (S13 to S16). Specifically, the UE can send a preamble via the Physical Random Access Channel (PRACH) (S13) and receive a random access response (RAR) to the preamble via the PDCCH and its corresponding PDSCH (S14). Afterward, the UE can send the Physical Uplink Shared Channel (PUSCH) using the scheduling information in the RAR (S15) and can perform a contention resolution procedure similar to that of the PDCCH and its corresponding PDSCH (which can be referred to as the process of receiving a contention resolution message) (S16).

[0155] After executing the above-mentioned procedures, the UE can perform PDCCH / PDSCH reception (S17) and PUSCH / Physical Uplink Control Channel (PUCCH) transmission (S18) as a typical uplink / downlink signal transmission process. The control information sent by the UE to the BS is called Uplink Control Information (UCI). UCI includes Hybrid Automatic Repeat and Request (HARQ) Acknowledgment (ACK) / Negative ACK (NACK), Scheduling Request (SR), Channel State Information (CSI), etc. CSI includes Channel Quality Indicator (CQI), Precoding Matrix Indicator (PMI), Rank Indicator (RI), etc. Typically, UCI is transmitted via PUCCH. However, when control information and data are to be transmitted simultaneously, UCI can be transmitted via PUSCH. Additionally, the UE can periodically transmit UCI via PUSCH according to network requests / instructions.

[0156] To ensure reasonable battery consumption when configuring bandwidth adaptive (BA), only one uplink BWP (bandwidth part) and one downlink BWP, or only one downlink / uplink BWP pair for each uplink carrier, can be activated at a time in the active serving cell, while all other BWPs configured in the UE are disabled. In the disabled BWPs, the UE does not monitor the PDCCH and does not perform transmissions on the PUCCH, PRACH, and UL-SCH.

[0157] For BA (Balance of Entity), the UE's RX and TX bandwidths are not necessarily as wide as the cell's bandwidth and can be adjusted. That is, commands can be used to change the bandwidth (e.g., reducing it for low-activity periods to save power), move its position in the frequency domain (e.g., to increase scheduling flexibility), and change the subcarrier spacing (e.g., to allow different services). A subset of the cell's entire bandwidth is called the Bandwidth Part (BWP), and BA is obtained by configuring the BWP for the UE and by notifying the UE of the currently active BWP among the configured BWPs. When BA is configured, the UE only needs to monitor the PDCCH on one active BWP. That is, it does not need to monitor the PDCCH across the entire downlink frequency of the cell. A BWP inactivity timer (independent of the DRX inactivity timer mentioned above) is used to switch the active BWP to the default BWP. Specifically, the timer restarts when the PDCCH is successfully decoded, and switches to the default BWP when the timer expires.

[0158] The following section describes integrated access and backhaul link (IAB). For ease of explanation, the proposed approach is illustrated based on the new RAT (NR) system; however, the scope of systems applying the proposed approach extends beyond NR systems to other systems such as 3GPP LTE / LTE-A systems.

[0159] One of the potential technologies aimed at realizing future cellular network configuration scenarios and applications is a technology that supports wireless backhaul and relay links, which enables flexible and high-density deployment of NR cells without scaling up the transport network.

[0160] Compared with LTE, it is expected that in NR, larger bandwidths will be available together with the native deployment of massive MIMO or multi-beam systems (e.g., mmWave spectrum), thus creating opportunities for the research, development, and configuration of integrated access and backhaul links. It enables a denser network of self-backhauled NR cells in a more integrated manner by establishing multiple control and data channels / processes defined as providing access to or from the UE. Such a system is referred to as integrated access and backhaul links (IAB).

[0161] The following definitions are made in this disclosure.

[0162] - AC(x): The access link between node (x) and the UE.

[0163] - BH(xy): The backhaul link between node (x) and node (y).

[0164] In this case, the node can refer to a donor gNB (DgNB) or a relay node (RN). Here, the DgNB or the donor node can be a gNB that provides the function of supporting the backhaul for the IAB node.

[0165] When there are relay node 1 and relay node 2, and relay node 1 is connected to relay node 2 via a backhaul link and relays the data transmitted and received by relay node 2, relay node 1 is called the parent node of relay node 2, and relay node 2 is called the child node of relay node 1.

[0166] The technical features separately described in one of the drawings in this specification can be implemented separately or simultaneously.

[0167] The following drawings are used to illustrate a specific example of this specification. The names of the specific devices or the names of the specific signals / messages / fields recorded in the drawings are only for illustration, so the technical features of this specification are not limited by the specific names used in the following drawings.

[0168] <PUSCH repetition>​​​​

[0170] 1) PUSCH repeat type A

[0171] Figure 12 This is an example of the repeating type A of PUSCH.

[0172] Reference Figure 12 PUSCH repetition type A is slot-based PUSCH repetition, and for each slot, repetition is performed using the same PUSCH start symbol position and PUSCH symbol length, such as... Figure 12 As shown. In this case, if the symbol resources constituting a specific PUSCH repetition contain invalid symbols that cannot be used for PUSCH transmission, they are discarded and the corresponding PUSCH repetition is not transmitted. For example, when a total of four PUSCH repetitions (Rep0, Rep1, Rep2, and Rep3) are transmitted in time slots N, N+1, N+2, and N+3 (one PUSCH repetition in each time slot), if the symbol resources constituting Rep1 include invalid symbols, the transmission of Rep1 is discarded, and only the transmissions of Rep0, Rep2, and Rep3 are performed. Therefore, the actual number of repetitions performed can be less than the configured number of repetitions.

[0173] For PUSCH repetition type A, frequency hopping can be configured for the UE via higher-layer parameters. One of two frequency hopping modes can be configured.

[0174] i) Intra-slot frequency hopping (intra-slot frequency hopping) is applicable to single-slot and multi-slot PUSCH transmission.

[0175] ii) Inter-slot frequency hopping is applicable to multi-slot PUSCH transmission.

[0176] 2) PUSCH repeat type B

[0177] Figure 13 This is an example of the repeating type B of PUSCH.

[0178] Reference Figure 13 Repeat PUSCH type B in units of the symbol length of the actual PUSCH sent. For example, as... Figure 13 In (a), when a PUSCH is sent over 10 symbols, PUSCH repetition is performed in units of 10 consecutive symbols. In this case, the repetition of PUSCH repetition time resources without considering slot boundaries, invalid symbols, etc., is called nominal repetition. Figure 13 (a) shows an example of configuring three nominal repeaters (denoted as N0, N1 and N2).

[0179] However, in the case of actual PUSCH repetition, a single PUSCH cannot be sent if it includes slot boundaries. That is, if the nominal PUSCH transmission includes slot boundaries (e.g., Figure 13 In (a), N0 and N2 are used as boundaries to execute two actual repetitions, such as... Figure 13 As shown in (b). For example, in the case where the time slot boundary is the boundary, the nominal repetition N0 is performed with two actual repetitions (such as A0, A1).

[0180] Additionally, only consecutive symbols can be used to perform a single PUSCH transmission. If invalid symbols exist in the time resource where a PUSCH repetition should be sent, then consecutive symbols are used to form an actual repetition, with the invalid symbols as the boundary. For example, if symbols #0 to #9 constitute a nominal repetition and symbols #3 to #5 are invalid symbols, then symbols #0 to #2 and symbols #6 to #9 (excluding the invalid symbols) each constitute an actual repetition.

[0181] Invalid symbols can include the following:

[0182] i) Downlink symbols configured via semi-static TDD UL-DL configuration.

[0183] ii) Invalid symbol pattern configured via RRC (which can be configured via an invalid symbol pattern indicator),

[0184] iii) SSB symbols configured via SIB1, and SSB symbols configured via "ServngCellConfigCommon".

[0185] iv) Symbols for the PDCCH of SIB1

[0186] v) Invalid symbols for DL-UL switching configured via RRC.

[0187] If a symbol that cannot be used for PUSCH transmission (e.g., a DL symbol indicated by DCI format 2_0) is included in an actual duplicate resource, the corresponding actual duplicate transmission is discarded and not performed.

[0188] Now, we will describe full-duplex operation.

[0189] In 5G, new service types such as extended reality (XR), AI-based services, and autonomous vehicles are emerging. These services feature dynamically changing traffic in both the downlink (DL) and uplink (UL) directions and require low latency for the traffic to be sent (e.g., packets). Traffic will explode in 5G services to support these diverse new use cases.

[0190] Existing semi-static or dynamic TDD UL / DL configurations have limitations such as transmission time delay and inter-carrier interference. Existing FDD methods have limitations in terms of effective frequency resource utilization in the DL / UL direction. Therefore, to achieve low latency and efficient resource utilization in NR, the introduction of full-duplex operation within a single carrier is being discussed.

[0191] Figure 14 An example of how to apply full-duplex within a carrier wave is shown.

[0192] Reference Figure 14 Full-duplex methods include, for example, in Figure 14 The sub-band full-duplex shown in (a) (hereinafter, it may be referred to as sub-band full-duplex or SBFD), and may also be considered as in Figure 14 The spectrum shared full-duplex (hereinafter, which may be referred to as SSFD) shown in (b) is shown.

[0193] In the case of SBFD, DL and UL transmit and receive using different frequency resources within the same carrier (e.g., carrier #0). That is, for the same time resource, different frequency resources are used in DL and UL.

[0194] In the case of SSFD, DL and UL transmit and receive using the same or overlapping frequency resources within the same carrier (e.g., carrier #0). That is, for the same time resources, the same or overlapping frequency resources can be used in DL and UL.

[0195] This full-duplex (FD) operation can also be used in conjunction with existing half-duplex (HD) operations. For example, some time resources used for existing half-duplex-based TDD operations can be used for full-duplex operations. SBFD or SSFD operations can be performed on the time resources used for full-duplex operations.

[0196] Figure 15 An example is shown where time resources operating in half-duplex (HD) and time resources operating in full-duplex (FD) (e.g., SBFD or SSFD) coexist.

[0197] exist Figure 15 In (a), some time resources that are SBFD (=SBFD) operations are designated as SBFD, while time resources that are HD operations are designated as HD. Figure 15 In (b), some time resources used as SSFD operations are designated as SSFD, while time resources used as HD operations are designated as HD. The unit of time resource can be, for example, a time slot or a symbol.

[0198] In the time resources used for SBFD operation, some frequency resources are used as DL resources, while others are used as UL resources. Between the DL and UL frequency resources, there may be a guard subband that is unused and empty for both DL and UL. The guard subband may also be referred to by other terms, such as guard frequency resources or guard subcarriers.

[0199] In the time resources utilized for SSFD operation, the entire frequency resource can be used for both DL and UL. Alternatively, to reduce the impact of interference from other adjacent carriers (this can be called ACI (Adjacent Carrier Interference)), some frequency resources located at one or both ends of the carrier can be excluded from DL and / or UL. That is, one or both ends of the carrier can be used as an unused guard band (guard subband) for both DL and UL. Alternatively, to reduce ACI on UL reception, one or both ends of the carrier can be used solely for DL ​​transmission.

[0200] In this disclosure, the time slot resources used for HD operations are referred to as HD time slots, and the time slot resources used for SBFD operations and SSFD operations are referred to as SBFD time slots and SSFD time slots, respectively. SBFD time slots and SSFD time slots are also collectively referred to as FD time slots.

[0201] In this disclosure, among all frequency resources used for FD operation, for convenience, frequency resources operating in DL can be referred to as DL subbands, and frequency resources operating in UL can also be referred to as UL subbands.

[0202] In 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 or different frequency resources at the same time.

[0203] Alternatively, only the base station can perform full-duplex operation, while the UE can perform half-duplex operation. The base station can simultaneously perform DL and UL transmission and reception using the same or different frequency resources at the same time, but the UE only performs DL reception or UL transmission in specific time resources. In this case, the base station performs full-duplex operation by simultaneously performing DL transmission and UL reception with different UEs.

[0204] This disclosure is described under the assumption that the base station performs / supports full-duplex operation, but the UE performs / supports half-duplex operation. However, the contents of this disclosure may still apply even if both the base station and the UE perform / support full-duplex operation.

[0205] Based on this discussion, this disclosure proposes a method for UE PUSCH transmission during in-carrier full-duplex operation when a PUSCH transmission includes both SBFD symbols and non-SBFD symbols.

[0206] In the following text, the term "network" can be interpreted as gNB or CU / DU. Furthermore, the term "UE" can be interpreted as the MT (Mobile Terminal) of the IAB node or the MT of the NCR-MT (Network Control Repeater).

[0207] A. Characteristics of DL / UL time / frequency resources used for SBFD and SSFD operations

[0208] A cell (base station) can perform both DL transmission and UL reception in the same time resource within an FD scheme (e.g., SBFD or SSFD). For example, a base station can perform HD operation in a first time resource and FD operation in a second time resource (which can be a time resource other than the first time resource).

[0209] The first time resource for performing HD operation spans frequency resources encompassing the entire system bandwidth, performing either DL or UL operation. Within the first time resource for HD operation, the network performs DL operation via time resource 1-1 and UL operation via time resource 1-2. At this time, time resources 1-1 and 1-2 do not overlap.

[0210] In the second time resource for performing FD operation, the network performs DL operation using all or part of the frequency resources (first frequency resources) in the frequency resources of the system BW constituting the cell, and performs UL operation using all or part of the frequency resources (second frequency resources).

[0211] Figure 16 Examples of first time resources, second time resources, first frequency resources, and second frequency resources are shown.

[0212] Reference Figure 16 In (a), the operation is performed as HD in the first time resource (denoted by A). In the second time resource (denoted by B), for example, it can be performed as SBFD. In the first time resource, the resource indicated by DL corresponds to the 1-1 time resource described above, and the resource indicated by UL corresponds to the 1-2 time resource described above.

[0213] Reference Figure 16 (b) In the second time resource, the frequency resource for DL ​​operation corresponds to the first frequency resource, and the frequency resource for UL operation corresponds to the second frequency resource.

[0214] Figure 17Another example of first time resources, second time resources, first frequency resources, and second frequency resources is shown.

[0215] Reference Figure 17 In (a), in the first time resource (labeled A), the device operates as a half-duplex. In the second time resource (labeled B), the device may, for example, operate as an SSFD. In the first time resource, the resource labeled DL corresponds to the first time resource described above, and the resource labeled UL corresponds to the second time resource described above.

[0216] Reference Figure 17 (b) In the second time resource, the frequency resource for DL ​​and DL+UL operations corresponds to the first frequency resource described above, and the frequency resource for DL+UL operations corresponds to the second frequency resource described above.

[0217] The first frequency resource and / or the second frequency resource may have all or some of the following characteristics.

[0218] 1) During SBFD operation, the first and second frequency resources do not overlap. This is to ensure that DL and UL operations are performed using different frequency resources. At this time, there may be frequency resources that do not correspond to both the first and second frequency resources, and these frequency resources are referred to as guard subbands or guard frequency resources. These guard frequency resources may be needed to reduce interference from DL transmissions to UL reception. Guard frequency resources can be located between the first and second frequency resources.

[0219] 2) During SSFD operation, the first and second frequency resources may overlap. In this case, there may be frequency resources that do not correspond to both the first and second frequency resources, and these frequency resources are referred to as guard subbands or guard frequency resources. These guard frequency resources may be needed to reduce interference from DL transmissions on adjacent carriers to UL reception, and / or to reduce interference from DL transmissions to UL receptions on adjacent carriers.

[0220] 3) During SBFD operation, the second frequency resource can consist of contiguous frequency resources, while the first frequency resource can consist of discontinuous frequency resources. In this case, the first frequency resource can consist of multiple (e.g., two) discontinuous sets, and each set can consist of contiguous frequency resources. This is to reduce interference from DL transmissions on adjacent carriers to the UL resource by placing the second frequency resource used for DL ​​at the center of the frequency resources constituting the cell. Conversely, the first frequency resource can consist of contiguous frequency resources, while the second frequency resource can consist of discontinuous frequency resources. In this case, the second frequency resource can consist of multiple (e.g., two) discontinuous sets, and each set can consist of contiguous frequency resources. This is to reduce interference from DL transmissions on adjacent carriers to the UL resource by placing the second frequency resource used for DL ​​at the center of the frequency resources constituting the cell.

[0221] 4) When performing SSFD operation, the second frequency resource can consist of some frequency resources from the first frequency resource. In this case, the second frequency resource can be configured to have X fewer physical resource blocks (PRBs) than the first frequency resource on one or both sides of the carrier. This is to reduce interference from DL transmissions on adjacent carriers to UL reception.

[0222] The network determines the "first time resource" and "second time resource" as described above, as well as the "first frequency resource" and "second frequency resource", and provides some or part of the corresponding information to the UE.

[0223] For FD (SBFD and / or SSFD) operations in a cell, the UE can determine information about the time resources (hereinafter referred to as SBFD symbols) for the SBFD (and / or SSFD) operation. For this purpose, information about SBFD symbols can be set from the network to the UE.

[0224] When a specific time resource is set as a time resource operating in SBFD mode (SBFD symbol), both DL (Deep Length) and UL (Ultra Length) resources can exist within that time resource. In this case, if there is no UL signal to be received by the base station in that time resource, the base station can perform only DL transmission. In SBFD resources, DL transmission is only performed within the DL subband. Therefore, even if there is no UL signal to be transmitted in the UL subband, only DL transmission can be performed within the DL subband.

[0225] In this scenario, if the base station has no UL transmissions to receive, even if the resources at a specific time are designated as SBFD symbols, it can consider performing DL transmissions both outside and within the DL subband to improve DL throughput. In other words, it can consider performing DL transmissions across the entire frequency band.

[0226] In other words, for resources identified as SBFD symbols, it is possible to consider reverting to TDD operation, where DL or UL operation is performed across the entire frequency band, rather than SBFD operation on the DL / UL subband.

[0227] In resources not designated as SBFD symbols, the UE can perform TDD (half-duplex) operations like a regular UE. That is, it can use the entire frequency resources of the cell to perform only DL or UL operations.

[0228] The UE can receive SBFD symbol information from the network. Based on this, the UE can determine whether a specific symbol is an SBFD symbol or a non-SBFD symbol.

[0229] i) If the UE determines that a particular symbol is a non-SBFD symbol, it can perform conventional operations on that symbol (or determine that conventional operations should be performed).

[0230] ii) If the UE determines that a particular symbol is an SBFD symbol, then it determines that the symbol is a symbol from the cell's perspective that can perform SBFD operations.

[0231] The UE may not need to receive configuration information for SBFD symbols from the network. In this case, i) the UE can identify all symbols as non-SBFD symbols. Therefore, the UE can operate on all symbols as in conventional TDD.

[0232] Alternatively, ii) if the UE does not receive configuration information for SBFD symbols from the network, the UE may identify all symbols as SBFD symbols.

[0233] If the UE determines that a specific symbol is an SBFD symbol, then i) typically, the UE can perform DL reception in the DL subband and UL transmission in the UL subband during the time resources when the cell is determined to be operating in SBFD. ii) Alternatively, the base station can consider performing only DL transmission or UL reception during the time resources when the cell is determined to be operating in SBFD, or perform DL transmission or UL reception across the entire frequency band as needed (capable of receiving DL or UL scheduling).

[0234] The UE can determine the UL subband and DL subband based on the network configuration.

[0235] i) The UE receives information about the UL subband and DL subband from the network and can determine the frequency resources that constitute the UL subband and DL subband.

[0236] ii) Alternatively, the UE can receive information about the UL subband from the network and determine the frequency resources constituting the UL subband. In this case, within the frequency resources constituting the system BW, the remaining frequency resources other than those configured / determined as UL subbands can be determined as DL subbands. Additionally, if the UE is configured with frequency resources constituting a guard subband, the remaining frequency resources within the frequency resources constituting the system BW, other than those configured / determined as UL and guard subbands, can be determined as DL subbands.

[0237] iii) Alternatively, the UE can receive information about the DL subband from the network and determine the frequency resources constituting the UL subband from it. In this case, within the frequency resources constituting the system BW, the remaining frequency resources other than those configured / determined as DL subbands can be determined as UL subbands. Additionally, if the UE is configured with frequency resources constituting a guard subband, the remaining frequency resources within the frequency resources constituting the system BW other than those configured / determined as DL subbands and guard subbands can be determined as UL subbands.

[0238] In this disclosure, time resources operated with SBFD or SBFD symbols may refer to the aforementioned "second time resource". Additionally, time resources operated with TDD, time resources operated with HD, TDD symbols, or HD symbols in this disclosure may refer to the aforementioned "first time resource".

[0239] The DL subband mentioned in this disclosure may refer to the aforementioned "first frequency resource". Furthermore, the UL subband mentioned in this disclosure may refer to the aforementioned "second frequency resource".

[0240] Based on the above, this disclosure describes a PUSCH transmission method for a UE during in-carrier full-duplex operation when a PUSCH transmission includes both SBFD symbols and non-SBFD symbols.

[0241] Although this disclosure is described in the context of assuming the transmission of PUSCH (including TBoMS), the contents of this disclosure can also be applied to the reception of PDSCH and the transmission of PUCCH.

[0242] This disclosure assumes SBFD operation, in which a cell simultaneously performs DL and UL using different frequency resources (subbands) within the same time resource. However, the content of this disclosure can also be applied to cells performing SSFD operation.

[0243] Figure 18 This illustrates the case where the symbol resources allocated for PUSCH transmission within a time slot include both SBFD symbols and non-SBFD symbols.

[0244] Reference Figure 18 In the case of PUSCH repetition type A and / or TBoMS transmission, a PUSCH / TBoMS transmission within a time slot consists of consecutive symbol resources within the time slot.

[0245] When a time slot contains both non-SBFD and SBFD symbols, the symbol resources allocated within the time slot for PUSCH (including TBoMS) transmissions can include both SBFD and non-SBFD symbols, such as... Figure 18 As shown.

[0246] For PUSCH repetition type B, a nominal repetition consists of contiguous symbol resources within a time slot or between two adjacent time slots. If the nominal repetition includes time slot boundaries, the actual repetition is defined by those time slot boundaries. Therefore, the actual repetition consists of contiguous symbol resources within a time slot.

[0247] Figure 19 The example illustrates the case where symbol resources allocated for PUSCH transmission in multiple time slots include both SBFD symbols and non-SBFD symbols.

[0248] Reference Figure 19 Time slot #N contains both SBFD and non-SBFD symbols. Time slot #N+1 contains only SBFD symbols.

[0249] In this case, there may be a situation where the symbol resources allocated / configured for PUSCH transmission include both SBFD symbols and non-SBFD symbols.

[0250] PUSCH transmission in SBFD symbols and PUSCH transmission in non-SBFD symbols may differ in several ways.

[0251] In SBFD symbols, if not all PRB resources allocated for PUSCH transmission are included in the UL subband, the number of PRBs used in each of the PUSCH transmissions in SBFD symbols and non-SBFD symbols can be different.

[0252] If the number of PRBs used in PUSCH transmission in an SBFD symbol is different from the number of PRBs used in a non-SBFD symbol (or there may be other reasons besides the difference in the number of PRBs), the UL transmit power (Tx power) of the UE in the SBFD symbol and the non-SBFD symbol may be different.

[0253] From the base station's perspective, the antenna / panel / RF configurations for UL reception in SBFD symbols and non-SBFD symbols are different. Therefore, the channels, UL reception beams (Rx beams), etc., in the two resources can be different.

[0254] When performing PUSCH transmission using both non - SBFD symbols and SBFD symbols at the same transmission occasion, the UE may need to apply different PUSCH transmission methods according to 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 according to the symbol type (SBFD / non - SBFD symbol).

[0255] Therefore, when the UE uses both non - SBFD symbols and SBFD symbols to perform a single PUSCH transmission within a time slot, several problems may occur.

[0256] Considering these problems, the present disclosure proposes a PUSCH transmission method for the UE when a PUSCH transmission is configured to include both SBFD symbols and non - SBFD symbols.

[0257] Although the present disclosure describes a transmission method according to the transmission symbol configuration of a PUSCH transmission (transmission occasion), it can also be applied to the case where the PUSCH is repeatedly transmitted K times.

[0258] Although the content of the present disclosure is described under the assumption of the transmission of PUSCH (including TBoMS), the content of the present disclosure can also be applied to the reception of PDSCH and the transmission of PUCCH.

[0259] <A. PUSCH / TBoMS Transmission within a Time Slot>

[0260] A PUSCH transmission method for the UE is proposed when a single PUSCH transmission within a time slot includes both SBFD symbols and non - SBFD symbols. The single PUSCH transmission within a time slot may include TBoMS transmission within the time slot. This section can be applied to PUSCH repeated transmission according to PUSCH repetition type A.

[0261] When the PUSCH transmission includes both SBFD symbols 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 according to an indication / condition.

[0262] Method 1. If both non - SBFD symbols and SBFD symbols are included in the L (L is a natural number greater than or equal to 2) symbols allocated for PUSCH transmission within a specific time slot, the UE does not perform PUSCH transmission in that time slot.

[0263] Method 2. If the L symbols allocated for PUSCH transmission in the time domain within a specific time slot include both non-SBFD and SBFD symbols, and if all PRBs (Physical Resource Blocks) allocated for PUSCH transmission in the frequency domain are included in the PRB resources constituting the UL subband, then the UE performs PUSCH transmission using the L symbols in the time slot. Otherwise, the UE does not perform PUSCH transmission in the time slot.

[0264] Method 3. If the L symbols allocated for PUSCH transmission in the time domain within a specific time slot include both non-SBFD symbols and SBFD symbols, then PUSCH transmission is performed using the L symbols in the time slot by utilizing the PRB (or RBG) resources included in the UL subband from the PRB (or RBG) resources allocated for PUSCH transmission in the frequency domain. That is, PUSCH transmission is performed using the L symbols in the time slot by utilizing the PRB (or RBG) resources included in the UL subband not only in the SBFD symbols but also in the non-SBFD symbols.

[0265] Method 4. If the L symbols allocated for PUSCH transmission in the time domain within a specific time slot include both non-SBFD symbols and SBFD symbols, then the UE assumes (or determines) that all L symbols are SBFD symbols, and based on this, performs PUSCH transmission for the L symbols in the corresponding time slot.

[0266] Method 5. The UE can perform PUSCH transmission using only symbol resources with a specific symbol type as follows.

[0267] Operation 5-1: If a specific time slot contains at least one non-SBFD symbol, the UE does not perform PUSCH transmission in that time slot. In this case, if all symbols in the time slot consist of SBFD symbols, the UE performs PUSCH transmission in that time slot.

[0268] Alternatively, if the symbol resources allocated for PUSCH transmission in a specific time slot include at least one non-SBFD symbol, the UE does not perform PUSCH transmission in that time slot. In this case, if all symbol resources allocated for PUSCH transmission in a specific time slot consist of SBFD symbols, the UE performs PUSCH transmission in that time slot.

[0269] Operation 5-2: If a specific time slot includes at least one SBFD symbol, the UE does not perform PUSCH transmission in that time slot. In this case, if all symbols in the time slot consist of non-SBFD symbols, the UE performs PUSCH transmission in that time slot.

[0270] Alternatively, if the symbol resources allocated for PUSCH transmission in a specific time slot include at least one SBFD symbol, the UE does not perform PUSCH transmission in that time slot. In this case, if all symbol resources allocated for PUSCH transmission in a specific time slot consist of non-SBFD symbols, the UE performs PUSCH transmission in that time slot.

[0271] In this case, the UE can perform operation 5-1 or operation 5-2 according to the following criteria / conditions / instructions.

[0272] Option 1. If all symbols in the first time slot indicating PUSCH transmission consist of SBFD symbols, or if all symbols allocated for PUSCH transmission in the first time slot indicating PUSCH transmission consist of SBFD symbols, then the UE applies operation 5-1 above. Otherwise, the UE applies operation 5-2 above.

[0273] Option 2. If all symbols in the first time slot indicating PUSCH transmission consist of non-SBFD symbols, or if all symbols allocated for PUSCH transmission in the first time slot indicating PUSCH transmission consist of non-SBFD symbols, then the UE applies operation 5-1 above. Otherwise, the UE applies operation 5-2 above.

[0274] Option 3. The UE instructs the application of Operation 5-1 or Operation 5-2 via the network. To do this, the UE can receive information from the network regarding the symbol type (SBFD symbol or non-SBFD symbol) used for PUSCH transmission via RRC, MAC-CE, DCI signaling, etc. For example, this can be indicated via the DCI that schedules the PUSCH.

[0275] At this point, the applicability of methods 2, 3, and 4 can vary depending on the implementation method of the base station or the transmission method of the UE. With this in mind, different methods can be applied based on indications from the base station. For example, method 3 or method 1 can be applied based on indications from the base station. For example, these indications can be transmitted to the UE via RRC signaling.

[0276] For PUSCH transmission within a specific time slot, if PUSCH transmission is not performed through the above operations, the UE may exclude the time slots constituting the PUSCH transmission from the available time slots. That is, when PUSCH is repeatedly transmitted K times, the time slots in which PUSCH was not transmitted for the above reasons will not be included in the K available time slots for setting up PUSCH transmission.

[0277] At this time, if a PUSCH is not transmitted on SBFD symbols and / or non-SBFD symbols semi-statically determined by RRC and / or MAC-CE in a specific time slot, then that time slot is not included in the available time slots constituting the PUSCH transmission. On the other hand, for a time slot in which a PUSCH is not transmitted on SBFD symbols and / or non-SBFD symbols determined by using DCI or DCI that does not schedule the PUSCH, PUSCH transmission is not performed, but that time slot may be included in the available time slots constituting the PUSCH transmission.

[0278] <Nominal / actual repeated transmission of PUSCH repetition type B>

[0279] For the transmission of PUSCH repetition type B, when the symbol resources for one nominal repetition or actual repeated transmission include both SBFD symbols and non-SBFD symbols, a PUSCH transmission method for the UE is proposed.

[0280] The UE may apply at least one of the following methods to transmit the nominal repetition or actual repetition. Alternatively, the UE may apply different methods according to an indication / condition.

[0281] Method 1. If both non-SBFD symbols and SBFD symbols are included in L (L is a natural number greater than or equal to 2, the same hereinafter) symbols constituting a specific nominal repetition, the UE does not perform the transmission of the corresponding nominal repetition.

[0282] Alternatively, if both non-SBFD symbols and SBFD symbols are included in L' (L' is a natural number less than L, i.e., L' <= L, the same hereinafter) symbols constituting a specific actual repetition, the UE does not perform the transmission of the corresponding actual repetition.

[0283] Method 2. If the L symbols constituting a specific nominal repetition include both non-SBFD symbols and SBFD symbols, and if all the PRBs allocated for PUSCH transmission are included in the PRB resources constituting the UL sub-band, the UE uses the L symbols to perform the transmission of the nominal repetition. Otherwise, the UE does not perform the transmission of the nominal repetition.

[0284] Alternatively, if the L' (<= L) symbols constituting a specific actual repetition include both non-SBFD symbols and SBFD symbols, and if all the PRBs allocated for PUSCH transmission are included in the PRB resources constituting the UL sub-band, the UE uses the L' symbols to perform the transmission of the actual repetition. Otherwise, the UE does not perform the transmission of the actual repetition.

[0285] Method 3. If the L symbols constituting a specific nominal repeat include both non-SBFD symbols and SBFD symbols, then the nominal repeat transmission is performed using the PRB (or RBG) resources included in the UL subband from the PRB (or RBG) resources allocated to PUSCH transmission. That is, nominal repeat transmission is performed using L symbols by utilizing the PRB (or RBG) resources included in the UL subband from both SBFD and non-SBFD symbols.

[0286] Alternatively, if both non-SBFD symbols and SBFD symbols are included in the L' (<=L) symbols constituting a particular actual repeat, then the actual repeat transmission is performed using L' symbols by utilizing the PRB (or RBG) resources included in the UL subband from the PRB (or RBG) resources allocated to PUSCH transmission. In other words, the actual repeat transmission is performed using L' symbols by utilizing the PRB (or RBG) resources included in the UL subband from both SBFD and non-SBFD symbols.

[0287] Method 4. If the L symbols constituting a particular nominal repetition include both non-SBFD symbols and SBFD symbols, then the UE assumes (or determines) that all L symbols are SBFD symbols, and based on this, uses the L symbols to perform nominal repetition transmission.

[0288] Alternatively, if the L' (<= L) symbols constituting a particular actual repetition include both non-SBFD symbols and SBFD symbols, then the UE assumes (or determines) that all L' symbols are SBFD symbols, and based on this, uses L' symbols to perform the actual repetition transmission.

[0289] Method 5. A method for including SBFD or non-SBFD symbols in the invalid symbols used to determine the symbol resources constituting the actual repetition. Therefore, these symbols are not included in the symbols performing the actual repetition.

[0290] At this point, it can be determined as follows whether a symbol in an SBFD symbol or a non-SBFD symbol is included in the invalid symbols.

[0291] Alternative Option 1: The UE receives an indication from the base station regarding which symbol (SBFD symbol or non-SBFD symbol) is included in the invalid symbols. This indication can be provided via RRC, MAC-CE, and / or DCI signaling.

[0292] Alternative Option 2. Invalid symbols include those that are not of the same type as the symbols used to transmit the PUSCH, based on the indication of the symbol type. For example, the network can indicate the symbol type (SBFD symbol / non-SBFD symbol) of the symbol resources used for PUSCH transmission to the UE via the DCI that schedules the PUSCH. In other words, it can be indicated whether to perform PUSCH transmission assuming SBFD symbols or non-SBFD symbols. For example, if the UE is instructed to perform PUSCH transmission assuming SBFD symbols, non-SBFD symbols are identified as invalid. Conversely, if the UE is instructed to perform PUSCH transmission assuming non-SBFD symbols, SBFD symbols are identified as invalid.

[0293] Alternative Option 3: If the first symbol in a nominal repetition is a non-SBFD symbol, then the SBFD symbol is included in the invalid symbols. Additionally, if the first symbol in a nominal repetition is an SBFD symbol, then the non-SBFD symbol is included in the invalid symbols.

[0294] Alternative Option 4: When the number of repetitions of PUSCH repetition type B is K, if the first symbol among the symbols constituting the first nominal repetition is a non-SBFD symbol, then the SBFD symbol is included in the invalid symbols. Furthermore, if the first symbol among the symbols constituting the first nominal repetition is an SBFD symbol, then the non-SBFD symbol is included in the invalid symbols.

[0295] Additionally, for specific nominal repetitions, this method can be applied to perform PUSCH transmissions where not all PRBs allocated to PUSCH transmissions are included in the PRB resources constituting the UL subband.

[0296] Method 6. If the L symbols constituting a particular nominal repeat include both non-SBFD symbols and SBFD symbols, then the nominal repeat is segmented into actual repeats around the boundaries of SBFD symbol resources and non-SBFD symbol resources.

[0297] For example, in Figure 19 Of the four symbols constituting the nominal Rep2, the first and second symbols are SBFD symbols, while the third and fourth symbols are non-SBFD symbols. In this case, based on the boundary between SBFD symbol resources and non-SBFD symbol resources, the first and second symbols constitute one actual repetition, and the third and fourth symbols constitute another actual repetition. This will be referred to... Figure 21 Detailed description.

[0298] Additionally, for specific nominal repetitions, this method can be applied to perform PUSCH transmissions where not all PRBs allocated to PUSCH transmissions are included in the PRB resources constituting the UL subband.

[0299] At this point, the applicability of the above methods can vary depending on the implementation method of the base station or the transmission method of the UE. With this in mind, different methods can be applied based on indications from the base station. For example, method 3 or method 1 can be applied based on indications from the base station. For example, these indications can be transmitted to the UE via RRC signaling.

[0300] Figure 20 An example of the operation method of a UE in a wireless communication system is given.

[0301] Reference Figure 20 The UE receives information for configuring parameters for an uplink data channel applicable to a specific frequency band (S201).

[0302] The aforementioned information may be, for example, a PUSCH-Config information element used to configure UE-specific PUSCH parameters applicable to a particular BWP.

[0303] The UE performs repeated transmission of the uplink data channel based on this information. However, during repeated 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 skips / drops the transmission of the specific uplink data channel (S202). That is, the transmission of the specific uplink data channel is dropped or the transmission of the specific uplink data channel is not performed.

[0304] Depending on the implementation, the UE may also receive a repetition type indicator that indicates the type of repetition of the uplink data channel.

[0305] For example, an indicator (e.g., “pusch-RepTypeIndicatorDCI-0-1”, “pusch-RepTypeIndicatorDCI-0-2”) indicating the type of PUSCH retransmission can be provided to the UE via an RRC message / information element (“PUSCH-Config”) used to configure UE-specific PUSCH parameters applicable to a specific bandwidth portion (BWP).

[0306] For example, “pusch-RepTypeIndicatorDCI-0-1” and “pusch-RepTypeIndicatorDCI-0-2” respectively indicate (notify) the UE whether to follow PUSCH repetition type A or PUSCH repetition type B operation for PUSCHs scheduled via DCI format 0_1, DCI format 0_2, and / or configuration license (CG) transmissions associated with activating DCI formats 0_1 / 0_2. “pusch-RepTypeIndicatorDCI-0-1” and “pusch-RepTypeIndicatorDCI-0-2” respectively activate PUSCH repetition type A or PUSCH repetition type B. “pusch-RepTypeIndicatorDCI-0-1” applies to DCI format 0_1, and “pusch-RepTypeIndicatorDCI-0-2” applies to DCI format 0_2.

[0307] The UE can determine the repetition type of the uplink data channel as either the first repetition type or the second repetition type based on the repetition type indicator.

[0308] For example, the first repetition type could be Physical Uplink Shared Channel (PUSCH) repetition type A, which is configured to perform repeated transmission of the uplink data channel in each time slot using the same start-transmit symbol and transmit symbol length. PUSCH repetition type A can include only one PUSCH repetition in a time slot.

[0309] Furthermore, the second repetition type can be PUSCH repetition type B, which is configured to perform uplink data channel repetition in units of transmitted symbol length. In PUSCH repetition type B, multiple PUSCH repetitions can be included in one time slot. When PUSCH is retransmitted in PUSCH repetition type B, if the transmitted symbol length includes time slot boundaries or invalid symbols, then two actual repetitions are performed with the time slot boundaries or invalid symbols as boundaries.

[0310] Regarding PUSCH repeat type A and PUSCH repeat type B, the above has already been referred to. Figure 12 and 13 It was described.

[0311] The UE can perform repeated transmission of the uplink data channel based on the determined repetition type.

[0312] At this point, if the time slots for transmitting uplink data channels include both full-duplex (FD) and half-duplex (HD) time resources, the uplink data channel transmission operation can be performed differently depending on the determined repetition type.

[0313] For example, FD time resources can be SBFD symbols that enable the UE to operate in SBFD (subband full-duplex) mode, and HD time resources can be non-SBFD symbols.

[0314] More specifically, when the uplink data channel (PUSCH) is repeatedly transmitted in the first repetition type (PUSCH repetition type A), if both FD time resources and HD time resources are included in a specific time slot for the transmission of the uplink data channel, then the transmission of the uplink data channel may not be performed in the specific time slot.

[0315] In other words, such as Figure 18 As illustrated, there may be cases where both non-SBFD symbols and SBFD symbols exist in a specific time slot, and the symbol resources allocated / configured for repeated transmission of PUSCH (including TBoMS) include both SBFD symbols and non-SBFD symbols.

[0316] In this case, if PUSCH repetition type A is set, PUSCH transmissions in a specific time slot can be discarded / skipped. According to this method, when PUSCH repetition type A is executed, only symbols of the same type exist in each time slot where PUSCH repetition is actually performed. Therefore, the complexity of executing PUSCH repetition type A can be reduced, and situations where transmit power / transmit / receive beams, etc., should be changed due to variations in the symbol type of each symbol within each time slot can be prevented.

[0317] Furthermore, when uplink data channels (PUSCH) are repeatedly transmitted in the second repetition type (PUSCH repetition type B), if both FD time resources and HD time resources are included in a specific time slot for uplink data channel transmission, the uplink data channels can be repeatedly transmitted using different actual transmission resources based on the boundary between FD time resources and HD time resources.

[0318] This method allows each PUSCH to be transmitted using only symbols of the same symbol type, thus preventing changes to the frequency resources, transmission power, and transmission beam for PUSCH transmission based on the transmitted symbols. Therefore, it reduces the complexity of PUSCH transmission and improves PUSCH transmission efficiency.

[0319] In some implementations, when the time resources constituting PUSCH transmission include both SBFD symbols and non-SBFD symbols, PUSCH transmission may or may not be performed based on the frequency resources allocated for PUSCH transmission. That is, when the time resources constituting PUSCH transmission include both SBFD symbols and non-SBFD symbols, whether or not PUSCH is transmitted may depend on the frequency resources allocated for PUSCH transmission.

[0320] For example, if the time resources constituting PUSCH transmission include both SBFD symbols and non-SBFD symbols, then in order for the UE to transmit PUSCH, the frequency resources (e.g., PRB) allocated for PUSCH transmission should not include resources other than the UL subband.

[0321] In other words, when the time resources constituting PUSCH transmission include both SBFD symbols and non-SBFD symbols, i) if the PRB resources allocated for PUSCH transmission include resources other than the UL subband, the UE does not transmit PUSCH, and ii) if all PRB resources allocated for PUSCH transmission are included in the UL subband, the UE can transmit PUSCH.

[0322] Figure 21 This example illustrates a PUSCH retransmission method when PUSCH is repeatedly transmitted in PUSCH repetition type B and includes different types of symbols (SBFD symbols and non-SBFD symbols) in a specific time slot.

[0323] like Figure 21 As shown, time slot #N includes both SBFD and non-SBFD symbols, while time slot #N+1 includes only SBFD symbols. In this case, there may be situations where the symbol resources allocated / configured for PUSCH transmission include both SBFD and non-SBFD symbols.

[0324] exist Figure 21 In the four symbols constituting nominal Rep2, the first and second symbols are SBFD symbols, while the third and fourth symbols are non-SBFD symbols. In this case, based on the boundary between SBFD and non-SBFD symbol resources, the first and second symbols constitute one actual repetition, and the third and fourth symbols constitute another. That is, among the four symbols constituting nominal Rep2, the uplink data channel is repeatedly transmitted using different actual transmission resources based on the boundary between FD time resources (SBFD symbols) and HD time resources (non-SBFD symbols).

[0325] Then, two actual repeated transmissions are performed based on the time slot boundaries.

[0326] Therefore, when PUSCH repetition type B is configured, it can be executed with a total of five actual repetitions in slot #N and one actual repetition in slot #N+1. Figure 21 The four nominal repeats (nominal repeat 0 to nominal repeat 3).

[0327] This method ensures that all symbols in each actual repeat have the same symbol type. That is, all symbols in each actual repeat are either SBFD symbols or non-SBFD symbols. Therefore, there is an advantage: it eliminates the need to change the transmit power or transmit / receive beam for each symbol in an actual repeat transmission.

[0328] Figure 22 The signaling process and operation method between the base station and the UE are illustrated.

[0329] Reference Figure 22 The base station provides TDD configuration information to the UE (S221).

[0330] TDD configuration information is an example of information used to configure the aforementioned HD time resources and HD frequency resources.

[0331] The base station provides FD resource information to the UE (S222). The FD resource information may be information that notifies the UE of FD time resources and / or FD frequency resources.

[0332] The base station provides the UE with a repeat type indicator (S223).

[0333] For example, the base station may provide an indicator (e.g., “pusch-RepTypeIndicatorDCI-0-1”, “pusch-RepTypeIndicatorDCI-0-2”) indicating the type of PUSCH retransmission via an RRC message / information element (“PUSCH-Config”) used to configure UE-specific PUSCH parameters applicable to a specific bandwidth portion (BWP).

[0334] The UE determines the repetition type (S224). For example, the UE can determine the type of PUSCH repetition as PUSCH repetition type A or PUSCH repetition type B based on the repetition type indicator.

[0335] When both FD time resources and HD time resources are included in the time slot for uplink data channel transmission, the UE performs uplink data channel transmission operations differently based on the determined repetition type (and / or whether all frequency resources set for uplink data channel transmission are included in the UL subband) (S225). The frequency resources configured for uplink data channel transmission can be dynamically set via DCI.

[0336] Reference Figures 18 to 21 The specific operation is described in detail.

[0337] Figure 23 The wireless device applicable to this specification is shown.

[0338] Reference Figure 23 The first wireless device 100 and the second wireless device 200 can transmit radio signals via various RATs (e.g., LTE and NR).

[0339] The first wireless device 100 may include at least one processor 102 and at least one memory 104, and additionally may include at least one transceiver 106 and / or at least one antenna 108. The at least one processor 102 (hereinafter simply referred to as the processor) may control at least one memory 104 (hereinafter simply referred to as the memory) and / or at least one transceiver 106 (hereinafter simply referred to as the transceiver), and may be configured to implement the descriptions, functions, processes, proposals, methods, and / or operational flows disclosed in this document. For example, the processor 102 may process information in the memory 104 to generate a first information / signal, and then transmit a radio signal including the first information / signal via the transceiver 106. Additionally, the processor 102 may receive a radio signal including a second information / signal via the transceiver 106, and then store information obtained from signal processing of the second information / signal in the memory 104. The memory 104 may be connected to the processor 102 and may store various pieces of information related to the operation of the processor 102. For example, memory 104 may store software code, including instructions for performing some or all of the processing controlled by processor 102 or for performing the descriptions, functions, processes, proposals, methods, and / or operation flowcharts disclosed in this document. Here, processor 102 and memory 104 may be part of a communication modem / circuit / chip designed to implement RAT (e.g., LTE or NR). Transceiver 106 may be connected to processor 102 and may transmit and / or receive radio signals via one or more antennas 108. Transceiver 106 may include a transmitter and / or a receiver. Transceiver 106 may be used interchangeably with a radio frequency (RF) unit. In this specification, a wireless device may refer to a communication modem / circuit / chip.

[0340] Processor 102 receives information for configuring parameters of an uplink data channel suitable for a specific frequency band and performs repeated transmission of the uplink data channel based on that information. During repeated transmission, if the time resources set for transmission of the specific uplink data channel include both full-duplex (FD) and half-duplex (HD) time resources, then transmission of the specific uplink data channel is skipped / discarded; or, based on the frequency resources set for transmission of the specific uplink data channel, transmission of the specific uplink data channel is skipped / discarded. (See also...) Figures 18 to 21 It describes a specific operation.

[0341] The second wireless device 200 may include one or more processors 202 and one or more memories 204, and may also include one or more transceivers 206 and / or one or more antennas 208. The processors 202 may control the memories 204 and / or the transceivers 206, and may be configured to implement the descriptions, functions, processes, proposals, methods, and / or operational flows disclosed in this document. For example, the processors 202 may process information in the memories 204 to generate third information / signals, which can then be transmitted via the transceivers 206 as radio signals including the third information / signals. Additionally, the processors 202 may receive radio signals including fourth information / signals via the transceivers 206, and may store information obtained by processing the fourth information / signals in the memories 204. The memories 204 may be connected to the processors 202 and may store various information related to the operation of the processors 202. For example, memory 204 may store software code, including instructions for performing some or all of the processing controlled by processor 202, or for performing the descriptions, functions, procedures, proposals, methods, and / or operation flowcharts disclosed in this document. Here, processor 202 and memory 204 may be part of a communication modem / circuit / chip designed to implement RAT (e.g., LTE or NR). Transceiver 206 may be connected to processor 202 and may transmit and / or receive radio signals via one or more antennas 208. Transceiver 206 may include a transmitter and / or a receiver. Transceiver 206 may be used interchangeably with an RF unit. In this specification, a wireless device may refer to a communication modem / circuit / chip. Processor 202 sends information to user equipment (UE) for configuring parameters for an uplink data channel suitable for a specific frequency band and performs repeated reception of the uplink data channel based on that information. In repeated reception, if the time resources for receiving a specific uplink data channel include both full-duplex (FD) and half-duplex (HD) time resources, then the reception of that specific uplink data channel is skipped / discarded, or the reception of that specific uplink data channel is skipped / discarded based on the frequency resources allocated for receiving that specific uplink data channel. (See reference...) Figures 18 to 21 It describes a specific operation.

[0342] The hardware components of wireless devices 100 and 200 will be described in more detail below. One or more protocol layers may be implemented by, but are not limited to, one or more processors 102 and 202.

[0348] Figure 24 An example of the structure of a signal processing module is shown. Here, signal processing can be performed... Figure 23 It is executed in processors 102 and 202.

[0349] Reference Figure 24 The transmitting device (e.g., processor, processor and memory, or processor and transceiver) in the UE or BS may include a scrambler 301, a modulator 302, a layer mapper 303, an antenna port mapper 304, a resource block mapper 305, and a signal generator 306.

[0350] The transmitting device can transmit one or more codewords. The encoded bits in each codeword are scrambled by a corresponding scrambler 301 and transmitted over the physical channel. The codeword can be referred to as a data string and can be equivalent to a transport block provided as a data block by the MAC layer.

[0351] The corresponding modulator 302 can modulate the scrambled bits into complex-valued modulation symbols. Modulator 302 can modulate the scrambled bits according to a modulation scheme to arrange complex-valued modulation symbols representing their positions on the signal constellation diagram. The modulation scheme is unrestricted, and m-PSK (m-phase shift keying) or m-QAM (m-quadrature amplitude modulation) can be used to modulate the coded data. The modulator can be referred to as a modulation mapper.

[0352] Complex-valued modulation symbols can be mapped to one or more transmission layers by layer mapper 303. Complex-valued modulation symbols on each layer can be mapped by antenna port mapper 304 for transmission at antenna ports.

[0353] Each resource block mapper 305 can map the complex-valued modulation symbols for each antenna port to appropriate resource elements in the virtual resource blocks allocated for transmission. The resource block mapper can map virtual resource blocks to physical resource blocks according to an appropriate mapping scheme. The resource block mapper 305 can allocate the complex-valued modulation symbols for each antenna port to appropriate subcarriers and multiplex the complex-valued modulation symbols according to the user.

[0354] Each signal generator 306 can modulate complex-valued modulation symbols, i.e., antenna-specific symbols, for each antenna port according to a specific modulation scheme (e.g., OFDM (Orthogonal Frequency Division Multiplexing)) to generate complex-valued time-domain OFDM symbol signals. The signal generator can perform an IFFT (Inverse Fast Fourier Transform) on the antenna-specific symbols and can insert a CP (Cyclic Prefix) into the IFFT-operated time-domain symbols. The OFDM symbols undergo digital-to-analog conversion and up-conversion before being transmitted to the receiving device through each transmit antenna. The signal generator may include an IFFT module, a CP insertion unit, a digital-to-analog converter (DAC), and an up-converter.

[0355] Figure 25 Another example illustrating the structure of a signal processing module in a transmitting device is given. Here, signal processing can be performed in the processor of the UE / BS, for example... Figure 23 Processors 102 and 202.

[0356] Reference Figure 25 The transmitting device (e.g., processor, processor and memory, or processor and transceiver) in the UE or BS may include a scrambler 401, a modulator 402, a layer mapper 403, a precoder 404, a resource block mapper 405, and a signal generator 406.

[0357] The transmitting device can scramble the encoded bits in the codeword using the corresponding scrambler 401, and then transmit the scrambled encoded bits through the physical channel.

[0358] 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 the positions on the signal constellation diagram. The modulation scheme is unrestricted and can use π / 2-BPSK (π / 2-binary phase shift keying), m-PSK (m-phase shift keying), or m-QAM (m-quadrature amplitude modulation) to modulate the coded data.

[0359] Complex-valued modulation symbols can be mapped to one or more transport layers by layer mapper 403.

[0360] Complex-valued modulation symbols on each layer can be pre-coded by pre-encoder 404 for transmission at antenna ports. Here, the pre-encoder can perform transform precoding on the complex-valued modulation symbols, followed by precoding. Alternatively, the pre-encoder can perform precoding without transform precoding. Pre-encoder 404 can process the complex-valued modulation symbols according to MIMO using multiple transmit antennas to output antenna-specific symbols and assign these symbols to the corresponding resource block mapper 405. The output z of pre-encoder 404 can be obtained by multiplying the output y of layer mapper 403 by an N×M precoding matrix W. Here, N is the number of antenna ports, and M is the number of layers.

[0361] Each resource block mapper 405 maps the complex-valued modulation symbol for each antenna port to the appropriate resource element in the virtual resource block allocated for transmission.

[0362] Resource block mapper 405 can assign complex-valued modulation symbols to appropriate subcarriers and multiplex complex-valued modulation symbols according to users.

[0363] Signal generator 406 can modulate complex-valued modulation symbols according to a specific modulation scheme (e.g., OFDM) to generate complex-valued time-domain OFDM symbol signals. Signal generator 406 can perform IFFT (Inverse Fast Fourier Transform) on antenna-specific symbols and can insert a CP (Cyclic Prefix) into the IFFT-operated time-domain symbols. The OFDM symbols undergo digital-to-analog conversion and up-conversion before being transmitted to the receiving device through each transmit antenna. Signal generator 406 may include an IFFT module, a CP insertion unit, a digital-to-analog converter (DAC), and an up-converter.

[0364] The signal processing of the receiving device can be the reverse process of the signal processing of the transmitting device. Specifically, the processor of the transmitting device decodes and demodulates the RF signal received through the antenna port of the transceiver. The receiving device may include multiple receiving antennas, and the signals received through the receiving antennas are recovered into baseband signals, and then multiplexed and demodulated according to MIMO to recover the data string intended to be transmitted by the transmitting device. The receiving device may include: a signal recovery unit that recovers the received signal into a baseband signal; a multiplexer for combining and multiplexing the received signals; and a channel demodulator for demodulating the multiplexed signal string into corresponding codewords. The signal recovery unit, multiplexer, and channel demodulator may be configured as integrated modules or independent modules for performing their functions. More specifically, the signal recovery unit may include: an analog-to-digital converter (ADC) for converting an analog signal into a digital signal; a CP removal unit for removing CP from the digital signal; a FET module for applying an FFT (Fast Fourier Transform) to the CP-removed signal to output a frequency domain signal; and a resource element demapper / equalizer for recovering the frequency domain symbols into antenna-specific symbols. The antenna-specific symbols are then recovered into the transport layer by a multiplexer, and the transport layer is recovered into codewords intended to be transmitted by a transmitting device by a channel demodulator.

[0388] Figure 32 The communication system 1 used in this specification is shown.

[0389] Reference Figure 32The communication system 1 used in this specification includes wireless devices, base stations (BS), and networks. Herein, a wireless device refers to a device that communicates using Radio Access Technology (RAT) (e.g., 5G New RAT (NR)) or Long Term Evolution (LTE) and may be referred to as a communication / radio / 5G device. Wireless devices may include, but are not limited to, robots 100a, vehicles 100b-1 and 100b-2, extended reality (XR) devices 100c, handheld devices 100d, home appliances 100e, Internet of Things (IoT) devices 100f, and artificial intelligence (AI) devices / servers 400. For example, a vehicle may include a vehicle with wireless communication capabilities, an autonomous vehicle, and a vehicle capable of communication between vehicles. Here, a vehicle may include an unmanned aerial vehicle (UAV) (e.g., a drone). XR devices may include augmented reality (AR) / virtual reality (VR) / mixed reality (MR) devices and may be implemented in the form of head-mounted displays (HMDs), head-up displays (HUDs) installed in vehicles, televisions, smartphones, computers, wearable devices, home appliances, digital signage, vehicles, robots, etc. Handheld devices may include smartphones, smart tablets, wearable devices (e.g., smartwatches or smart glasses), and computers (e.g., laptops). Home appliances may include televisions, refrigerators, and washing machines. IoT devices may include sensors and smart meters. For example, the BS and network can be implemented as wireless devices, and a particular wireless device 200a can operate as a BS / network node relative to other wireless devices.

[0390] Wireless devices 100a to 100f can connect to network 300 via BS200. AI technology can be applied to wireless devices 100a to 100f, and wireless devices 100a to 100f can connect to AI server 400 via network 300. Network 300 can be configured using a 3G network, a 4G (e.g., LTE) network, or a 5G (e.g., NR) network. Although wireless devices 100a to 100f can communicate with each other via BS200 / network 300, wireless devices 100a to 100f can also perform direct communication with each other without going through the BS / network (e.g., secondary link communication). For example, vehicles 100b-1 and 100b-2 can perform direct communication (e.g., vehicle-to-vehicle (V2V) / vehicle-to-everything (V2X) communication). In addition, IoT devices (e.g., sensors) can perform direct communication with other IoT devices (e.g., sensors) or other wireless devices 100a to 100f.

[0391] Wireless communication / connections 150a, 150b, or 150c can be established between wireless devices 100a to 100f / BS200 or between BS200 and BS200. In this document, wireless communication / connections can be established via various RATs (e.g., 5G NR), such as uplink / downlink communication 150a, secondary link communication 150b (or D2D communication), or inter-BS communication (e.g., relay, integrated access and backhaul (IAB)). Wireless devices and BS / wireless devices can transmit / receive radio signals to / from each other via wireless communication / connections 150a and 150b. For example, wireless communication / connections 150a and 150b can transmit / receive signals via various physical channels. To this end, at least a portion of various configuration information configuration processes, various signal processing processes (e.g., channel coding / decoding, modulation / demodulation, and resource mapping / demapping), and resource allocation processes for transmitting / receiving radio signals can be performed based on various proposals of this disclosure.

[0392] In addition, NR supports multiple parameter sets (or subcarrier spacing (SCS)) to support a variety of 5G services. For example, a 15kHz SCS can support wide-area coverage in traditional cellular bands. A 30kHz / 60kHz SCS supports dense urban areas, lower latency, and wider carrier bandwidth. A 60kHz or higher SCS uses a bandwidth greater than 24.25GHz to overcome phase noise.

[0393] NR bands can be defined as two types of frequency ranges (FR1, FR2). The values ​​of the frequency ranges can be changed. For example, the two types of frequency ranges (FR1, FR2) are shown in Table 5 below. For ease of explanation, in the frequency ranges used in NR systems, FR1 can represent "below 6 GHz" and FR2 can represent "above 6 GHz" and can also be referred to as millimeter wave (mmW).

[0394] [Table 5]

[0395] Frequency range specification Corresponding frequency range Subcarrier spacing (SCS) FR1 450MHz to 6000MHz 15, 30, 60kHz FR2 24250MHz to 52600MHz 60, 120, 240kHz

[0396] As mentioned above, the frequency range value in an NR system can be varied. For example, as shown in Table 6 below, FR1 can include a frequency band ranging from 410MHz to 7125MHz. That is, FR1 can include a frequency band of at least 6GHz (or 5850MHz, 5900MHz, 5925MHz, etc.). For example, the frequency band of at least 6GHz (or 5850MHz, 5900MHz, 5925MHz, etc.) included in FR1 can include unlicensed frequency bands. Unlicensed frequency bands can be used for various purposes, such as unlicensed frequency bands for vehicle-specific communications (e.g., autonomous driving).

[0397] [Table 6]
