Description

Method of operating a device in a wireless communication system and a device using the method

[0001] The present disclosure relates to a method of operating a device in a wireless communication system and a device using the method.

[0002] As more and more communication devices demand greater communication capacity, the need for improved mobile broadband communications over existing radio access technology (RAT) is emerging. Furthermore, massive Machine Type Communications (MTC), which connects numerous devices and objects to provide diverse services anytime, anywhere, is also a key issue to be considered in next-generation communications. Furthermore, communication system design that considers reliability and latency-sensitive services / terminals is being discussed. The introduction of next-generation radio access technologies that take enhanced mobile broadband communications, massive MTC, and URLLC (Ultra-Reliable and Low Latency Communication) into account is being discussed. For convenience, these technologies are referred to herein as 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 be performed simultaneously in a specific time resource. Half duplex (HD) operation is different from HD operation in that either downlink reception or uplink transmission can be performed only in a specific time resource. For FD operation, i) some frequency resources in the same time resource are allocated as downlink subbands and other some frequency resources are allocated as uplink subbands (this may be referred to as subband FD, or subband-wise full duplex (SBFD), ii) frequency resources that can be used for both downlink reception and uplink transmission in the same time resource may be allocated (this may be referred to as spectrum shared FD, or spectrum-sharing full duplex (SSFD)).

[0004] Within a specific slot, SBFD symbols that operate as SBFD and non-SBFD symbols that do not operate as SBFD may coexist. In this case, resources for uplink data channel transmission may be configured / allocated to include both SBFD and non-SBFD symbols. Then, since each symbol may have differences in transmittable frequency resources, transmit power, and transmit beam, problems may arise when a terminal transmits an uplink data channel using both SBFD and non-SBFD symbols.

[0005] The technical problem to be solved by the present disclosure is to provide a method of operating a device in a wireless communication system and a device using the method.

[0006] A method of operating a device in a wireless communication system and a device using the method are provided. According to the method, a terminal receives information used to set parameters of an uplink data channel applicable to a specific frequency band, and performs repetitive transmission of the uplink data channel based on the information. In the repetitive transmission, if both a full duplex (FD) time resource and a half duplex (HD) time resource are included in the time resources set for transmission of a specific uplink data channel, transmission of the specific uplink data channel is skipped.

[0007] In another aspect, a terminal, device, or computer-readable recording medium for executing the above method is provided.

[0008] In another aspect, a method of operating a base station and a base station using the method are provided. According to the method of operating the base station, the base station transmits to a terminal information used for setting parameters of an uplink data channel applicable to a specific frequency band, and repeatedly receives the uplink data channel based on the information. In the repeated reception, if both a full duplex (FD) time resource and a half duplex (HD) time resource are included in the time resources for receiving a specific uplink data channel, reception of the specific uplink data channel is skipped.

[0009] According to the method according to the present disclosure, by transmitting each PUSCH using only symbols of the same symbol type, it is possible to prevent frequency resources, transmission power, transmission beams, etc. for PUSCH transmission from changing depending on the transmission symbol.

[0010] It can reduce the complexity of PUSCH transmission and also increase PUSCH transmission efficiency.

[0043] In this specification, “A or B” can mean “only A,” “only B,” or “both A and B.” In other words, “A or B” in this specification can be interpreted as “A and / or B.” For example, “A, B or C” in this specification can mean “only A,” “only B,” “only C,” or “any combination of A, B, and C.”

[0044] As used herein, a slash ( / ) or a comma can mean "and / or." For example, "A / B" can mean "A and / or B." Accordingly, "A / B" can mean "only A," "only B," or "both A and B." For example, "A, B, C" can mean "A, B, or C."

[0048] Technical features individually described in a single drawing in this specification may be implemented individually or simultaneously.

[0049] Figure 1 illustrates a wireless communication system to which the present disclosure may be applied. This may also be referred to as an Evolved-UMTS Terrestrial Radio Access Network (E-UTRAN) or a Long Term Evolution (LTE) / LTE-A system.

[0050] E-UTRAN includes a base station (BS) 20 that provides a control plane and a user plane to a user equipment (UE) 10. The UE 10 may be fixed or mobile, and may be referred to by other terms such as a mobile station (MS), a user terminal (UT), a subscriber station (SS), a mobile terminal (MT), a wireless device, or a terminal. The base station (20) refers to a fixed station that communicates with the UE 10, and may be referred to by other terms such as an evolved-NodeB (eNB), a base transceiver system (BTS), or an access point.

[0051] Base stations (20) can be connected to each other via the X2 interface. The base station (20) is connected to an EPC (Evolved Packet Core, 30) via the S1 interface, more specifically, to an MME (Mobility Management Entity) via the S1-MME, and to an S-GW (Serving Gateway) via the S1-U.

[0052] The EPC (30) consists of an MME, an S-GW, and a P-GW (Packet Data Network-Gateway). The MME holds information about terminal access and capabilities, and this information is primarily used for terminal mobility management. The S-GW is a gateway with the E-UTRAN as its endpoint, and the P-GW is a gateway with the PDN as its endpoint.

[0053] The layers of the radio interface protocol between the terminal and the network can be divided into L1 (layer 1), L2 (layer 2), and L3 (layer 3) based on the three lower layers of the Open System Interconnection (OSI) standard model, which is widely known in communication systems. Among these, the physical layer belonging to layer 1 provides information transfer service using physical channels, and the RRC (Radio Resource Control) layer located in layer 3 controls radio resources between the terminal and the network. To this end, the RRC layer exchanges RRC messages between the terminal and the base station.

[0054] Figure 2 is a block diagram illustrating the radio protocol architecture for the user plane. Figure 3 is a block diagram illustrating the radio protocol architecture for the control plane. The user plane is a protocol stack for transmitting user data, and the control plane is a protocol stack for transmitting control signals.

[0055] Referring to Figures 2 and 3, the physical layer (PHY layer) provides information transfer services to upper layers using physical channels. The PHY layer is connected to its upper layer, the Medium Access Control (MAC) layer, through a transport channel. Data is transferred between the MAC layer and the PHY layer via the transport channel. Transport channels are classified based on how and with what characteristics data is transmitted over the wireless interface.

[0056] Data travels between different physical layers, i.e., between the physical layers of a transmitter and receiver, via a physical channel. This physical channel can be modulated using Orthogonal Frequency Division Multiplexing (OFDM) and utilizes time and frequency as radio resources.

[0057] The MAC layer's functions include mapping between logical channels and transport channels, and multiplexing / demultiplexing MAC service data units (SDUs) belonging to logical channels into transport blocks provided as physical channels on the transport channels. The MAC layer provides services to the RLC (Radio Link Control) layer through logical channels.

[0058] The functions of the RLC layer include concatenation, segmentation, and reassembly of RLC SDUs. To guarantee the various Quality of Service (QoS) required by 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 through automatic repeat request (ARQ).

[0059] The RRC (Radio Resource Control) layer is defined only in the control plane. The RRC layer is responsible for controlling logical, transport, and physical channels, including the configuration, reconfiguration, and release of radio bearers. An RB is a logical path provided by Layer 1 (PHY layer) and Layer 2 (MAC layer, RLC layer, PDCP layer) for data transmission between a terminal and the network.

[0060] The functions of the Packet Data Convergence Protocol (PDCP) layer in the user plane include the transmission of user data, header compression, and ciphering. The functions of the Packet Data Convergence Protocol (PDCP) layer in the control plane include the transmission of control plane data and encryption / integrity protection.

[0061] Establishing an RB refers to the process of defining the characteristics of the radio protocol layer and channel to provide a specific service, and setting specific parameters and operating methods for each. RBs can be further divided into two types: signaling RBs (SRBs) and data RBs (DRBs). SRBs are used as a conduit for transmitting RRC messages in the control plane, while DRBs are used as conduits for transmitting user data in the user plane.

[0062] When an RRC connection is established between the RRC layer of the terminal and the RRC layer of the E-UTRAN, the terminal is in an RRC connected state, otherwise it is in an RRC idle state.

[0063] Downlink transmission channels that transmit data from the network to the terminal include the Broadcast Channel (BCH), which transmits system information, and the downlink Shared Channel (SCH), which transmits user traffic or control messages. Traffic or control messages for downlink multicast or broadcast services may be transmitted through the downlink SCH or a separate downlink Multicast Channel (MCH). Meanwhile, uplink transmission channels that transmit data from the terminal to the network include the Random Access Channel (RACH), which transmits initial control messages, and the uplink Shared Channel (SCH), which transmits user traffic or control messages.

[0064] Logical channels that are located above the transport channel and are mapped to the transport channel include BCCH (Broadcast Control Channel), PCCH (Paging Control Channel), CCCH (Common Control Channel), MCCH (Multicast Control Channel), and MTCH (Multicast Traffic Channel).

[0065] A physical channel consists of multiple OFDM symbols in the time domain and multiple subcarriers in the frequency domain. A single subframe consists of multiple OFDM symbols in the time domain. A resource block is a resource allocation unit and consists of multiple OFDM symbols and multiple subcarriers. Additionally, each subframe can use specific subcarriers of specific OFDM symbols (e.g., the first OFDM symbol) of the subframe for the Physical Downlink Control Channel (PDCCH), i.e., the L1 / L2 control channel. A Transmission Time Interval (TTI) is a unit time for subframe transmission.

[0066] Below, we describe new radio access technology (new RAT, NR).

[0067] As more and more communication devices demand greater communication capacity, the need for improved mobile broadband communications over existing radio access technology (RAT) is emerging. Furthermore, massive Machine Type Communications (MTC), which connects numerous devices and objects to provide diverse services anytime, anywhere, is also a key issue to be considered in next-generation communications. Furthermore, communication system design that considers reliability and latency-sensitive services / terminals is being discussed. The introduction of next-generation radio access technologies that take into account enhanced mobile broadband communications, massive MTC, and URLLC (Ultra-Reliable and Low Latency Communication) is being discussed, and for convenience, these technologies are referred to as new RAT or NR in this disclosure.

[0068] Figure 4 illustrates the system architecture of a New Generation Radio Access Network (NG-RAN) to which NR is applied.

[0069] Referring to FIG. 4, the NG-RAN may include gNBs and / or eNBs that provide user plane and control plane protocol termination to the UE. FIG. 4 illustrates a case where only gNBs are included. The gNBs (eNBs) are connected to each other via Xn interfaces. The gNBs and eNBs are connected to the 5th generation core network (5G Core Network: 5GC) via the NG interface. More specifically, they are connected 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.

[0070] Figure 5 illustrates the functional division between NG-RAN and 5GC.

[0071] Referring to FIG. 5, the gNB can provide functions such as inter-cell radio resource management (Inter Cell RRM), radio bearer management (RB control), connection mobility control (Connection Mobility Control), radio admission control (Radio Admission Control), measurement configuration and provision, 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 (Session Management Function) can provide functions such as terminal IP address allocation and PDU session control.

[0072] Figure 6 illustrates a frame structure that can be applied in NR.

[0073] Referring to FIG. 6, a radio frame (hereinafter abbreviated as a frame) can be used for uplink and downlink transmission in NR. A frame has a length of 10 ms and can be defined as two 5 ms half-frames (Half-Frames, HF). A half-frame can be defined as five 1 ms sub-frames (Subframes, SF). A sub-frame can be divided into one or more slots, and the number of slots in a sub-frame depends on the Subcarrier Spacing (SCS). Each slot contains 12 or 14 OFDM (A) symbols depending on the CP (cyclic prefix). When a normal CP is used, each slot contains 14 symbols. When an extended CP is used, each slot contains 12 symbols. Here, the symbols can include an OFDM symbol (or a CP-OFDM symbol), an SC-FDMA symbol (or a DFT-s-OFDM symbol).

[0074] Table 1 below illustrates the subcarrier spacing configuration μ (also referred to as subcarrier spacing configuration).

[0075] [Table 1]

[0076]

[0077] Table 2 below shows the number of slots (N) in a frame according to the subcarrier spacing setting μ. frameμ slot ), number of slots in a subframe (N subframeμ slot ), number of symbols in the slot (N slot symb ) are examples.

[0078] [Table 2]

[0079]

[0080] In Fig. 6, examples are given for μ=0, 1, 2, and 3.

[0081] Table 2-1 below illustrates that when extended CP is used, the number of symbols per slot, the number of slots per frame, and the number of slots per subframe change depending on the SCS.

[0082] [Table 2-1]

[0083]

[0084] In an NR system, OFDM(A) numerologies (e.g., SCS, CP length, etc.) may be set differently between multiple cells that are merged into a single terminal. Accordingly, the (absolute time) interval of a time resource (e.g., SF, slot, or TTI) (conveniently referred to as TU (Time Unit)) consisting of the same number of symbols may be set differently between the merged cells.

[0085] Figure 7 illustrates a slot structure.

[0086] A slot can contain multiple symbols in the time domain. For example, in the case of a normal CP, one slot can contain 14 symbols (or 7 symbols), but in the case of an extended CP, one slot can contain 12 symbols (or 6 symbols). A carrier can contain multiple subcarriers in the frequency domain. A Resource Block (RB) can be defined as multiple (e.g., 12) consecutive subcarriers in the frequency domain. A Bandwidth Part (BWP) can be defined as multiple consecutive (P)RBs in the frequency domain, and can correspond to a single numerology (e.g., SCS, CP length, etc.). A carrier can contain up to N (e.g., 5) BWPs. Data communication is performed through activated BWPs, and only one BWP can be activated for a single terminal. In the resource grid, each element is referred to as a Resource Element (RE), to which one complex symbol can be mapped.

[0087] A PDCCH (physical downlink control channel) may be composed of one or more CCEs (control channel elements) as shown in Table 3 below.

[0088] [Table 3]

[0089]

[0090] That is, the PDCCH can be transmitted through a resource consisting of 1, 2, 4, 8, or 16 CCEs. Here, the CCEs are composed of 6 REGs (resource element groups), and one REG consists of one resource block in the frequency domain and one OFDM (orthogonal frequency division multiplexing) symbol in the time domain.

[0091] Monitoring refers to decoding each PDCCH candidate according to the DCI (downlink control information) format. The terminal monitors a set of PDCCH candidates in one or more core sets (CORESETs, described below) on the active DL BWP of each activated serving cell for which PDCCH monitoring is configured, according to the corresponding search space set.

[0092] In NR, a new unit called a control resource set (CORESET) can be introduced. A terminal can receive PDCCHs in a CORESET.

[0093] Figure 8 illustrates a core set.

[0094] Referring to Figure 8, the coreset is N in the frequency domain. CORESET RB It consists of N resource blocks and is in the time domain. CORESET symb ∈ {1, 2, 3} symbols. N CORESET RB, N CORESET symb can be provided by the base station via upper layer signals. As illustrated in Fig. 8, a core set may include multiple CCEs (or REGs).

[0095] A terminal may attempt PDCCH detection in units of 1, 2, 4, 8, or 16 CCEs within a core set. One or more CCEs for which PDCCH detection can be attempted may be referred to as PDCCH candidates.

[0096] A terminal can be configured with multiple core sets.

[0097] In conventional wireless communication systems (e.g., LTE / LTE-A), the control domain spans the entire system bandwidth used by the base station. Except for some terminals that support only narrow bandwidths (e.g., eMTC / NB-IoT terminals), all terminals must be able to receive radio signals across the entire system bandwidth of the base station to properly receive / decode the control information transmitted by the base station.

[0098] In contrast, NR introduces the aforementioned core set. A core set is a radio resource for control information that a terminal must receive. It can utilize only a portion of the system bandwidth in the frequency domain, rather than the entire bandwidth. Furthermore, it can utilize only a portion of the symbols within a slot in the time domain. The base station can assign a core set to each terminal and transmit control information through the assigned core set. In NR, a terminal can receive control information from the base station without necessarily receiving the entire system bandwidth.

[0099] The core set may include a terminal-specific core set for transmitting terminal-specific control information and a common core set for transmitting control information common to all terminals.

[0100] Meanwhile, in NR, depending on the application field, high reliability may be required, and in such a situation, the target block error rate (BLER) for downlink control information (DCI) transmitted through a downlink control channel (e.g., physical downlink control channel: PDCCH) may be significantly lower than in the prior art. One example of a method for satisfying such a requirement requiring high reliability is to reduce the amount of content included in the DCI and / or increase the amount of resources used when transmitting the DCI. In this case, the resources may include at least one of time domain resources, frequency domain resources, code domain resources, and spatial domain resources.

[0101] The following technologies / features can be applied in NR:

[0102] Self-contained subframe structure

[0103] Figure 9 illustrates an example of a frame structure for a new wireless access technology.

[0104] In NR, for the purpose of minimizing latency, a structure in which a control channel and a data channel are time-division multiplexed (TDM) within one TTI, as shown in Fig. 9, can be considered as one of the frame structures.

[0105] In Fig. 9, the hatched area represents a downlink control area, and the black area represents an uplink control area. Unmarked areas can be used for downlink data (DL data) transmission or uplink data (UL data) transmission. A characteristic of this structure is that downlink (DL) transmission and uplink (UL) transmission are sequentially performed within a single subframe, so that DL data can be sent and UL ACK / NACK (Acknowledgement / Not-acknowledgement) can also be received within the subframe. As a result, the time required for data retransmission when a data transmission error occurs is reduced, thereby minimizing the latency of the final data transmission.

[0106] In these data and control TDMed subframe structures, a time gap is required for the base station and terminal to transition from transmission mode to reception mode or from reception mode to transmission mode. To this end, some OFDM symbols at the transition point from DL to UL in the self-contained subframe structure can be set as a guard period (GP).

[0107] Figure 10 illustrates the structure of a self-contained slot.

[0108] In an NR system, a single slot may contain a DL control channel, DL or UL data, and a UL control channel. For example, the first N symbols in a slot may be used to transmit a DL control channel (hereinafter, referred to as a DL control region), and the last M symbols in the slot may be used to transmit a UL control channel (hereinafter, referred to as a UL control region). N and M are each integers greater than or equal to 0. A resource region (hereinafter, referred to as a data region) between the DL control region and the UL control region may be used for DL ​​data transmission or UL data transmission. As an example, the following configuration may be considered. Each section is listed in chronological order.

[0109] 1. DL only configuration

[0110] 2. UL only configuration

[0111] 3. Mixed UL-DL configuration

[0112] - DL area + GP (Guard Period) + UL control area

[0113] - DL control area + GP + UL area

[0114] DL area: (i) DL data area, (ii) DL control area + DL data area

[0115] UL domain: (i) UL data domain, (ii) UL data domain + UL control domain

[0116] In the DL control region, a PDCCH can be transmitted, and in the DL data region, a PDSCH (physical downlink shared channel) can be transmitted. In the UL control region, a PUCCH (physical uplink control channel) can be transmitted, and in the UL data region, a PUSCH (physical uplink shared channel) can be transmitted. In the PDCCH, downlink control information (DCI), such as DL data scheduling information and UL data scheduling information, can be transmitted. In the PUCCH, uplink control information (UCI), such as ACK / NACK (Positive Acknowledgement / Negative Acknowledgement) information for DL ​​data, CSI (Channel State Information) information, and SR (Scheduling Request), can be transmitted. GP provides a time gap when a base station and a terminal switch from transmission mode to reception mode or from reception mode to transmission mode. Some symbols at the time of switching from DL to UL within a subframe can be set as GP.

[0117] Analog Beamforming #1

[0118] In millimeter wave (mmW), the wavelength is shortened, allowing for the installation of multiple antenna elements in the same area. That is, in the 30 GHz band, the wavelength is 1 cm, allowing for a total of 100 antenna elements to be installed in a two-dimensional array at 0.5 wavelength (lambda) intervals on a 5 x 5 cm panel. Therefore, in mmW, multiple antenna elements are used to increase beamforming (BF) gain, thereby increasing coverage or throughput.

[0119] In this case, if there is a transceiver unit (TXRU) that allows transmission power and phase control for each antenna element, independent beamforming is possible for each frequency resource. However, it is not practical in terms of cost to install a TXRU for all 100 or so antenna elements. Therefore, a method of mapping multiple antenna elements to a single TXRU and controlling the direction of the beam with an analog phase shifter is being considered. This analog beamforming method has the disadvantage of being unable to perform frequency-selective beamforming because it can only create one beam direction for the entire band.

[0120] Hybrid beamforming (hybrid BF), which has B TXRUs, which is less than Q antenna elements, can be considered as an intermediate form between digital beamforming (Digital BF) and analog beamforming (Analog BF). In this case, depending on the connection method of the B TXRUs and Q antenna elements, the number of beam directions that can be transmitted simultaneously is limited to B or fewer.

[0121] Analog Beamforming #2

[0122] In NR systems, when multiple antennas are used, a hybrid beamforming technique that combines digital beamforming and analog beamforming is emerging. In this case, analog beamforming (or RF beamforming) performs precoding (or combining) at the RF end, which has the advantage of achieving performance close to digital beamforming while reducing the number of RF chains and D / A (or A / D) converters. For convenience, the hybrid beamforming structure can be expressed as N TXRUs and M physical antennas. Then, the digital beamforming for L data layers to be transmitted from the transmitter can be expressed as an N by L matrix, and the N converted digital signals are converted into analog signals through the TXRU, and then analog beamforming expressed as an M by N matrix is ​​applied.

[0123] System information of an NR system can be transmitted in a broadcasting manner. At this time, analog beams belonging to different antenna panels within one symbol can be transmitted simultaneously, and a method of introducing a beam reference signal (BRS), which is a reference signal (RS) transmitted by applying a single analog beam (corresponding to a specific antenna panel) to measure a channel for each analog beam, is being discussed. The BRS can be defined for multiple antenna ports, and each antenna port of the BRS can correspond to a single analog beam. At this time, unlike the BRS, a synchronization signal or xPBCH can be transmitted by applying all analog beams within an analog beam group so that any terminal can receive it well.

[0124] In NR, a synchronization signal block (SSB, or may be referred to as a synchronization signal and physical broadcast channel (SS / PBCH) in the time domain) may be composed of four OFDM symbols numbered in ascending order from 0 to 3 within the synchronization signal block, and a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a PBCH associated with a demodulation reference signal (DMRS) may be mapped to the symbols. As described above, the synchronization signal block may also be referred to as an SS / PBCH block.

[0125] In NR, multiple synchronization signal blocks can be transmitted at different times, and SSB can be used to perform initial access (IA), serving cell measurement, etc. Therefore, when the transmission timing and resources overlap with other signals, it is desirable to transmit SSB preferentially. To achieve this, the network can broadcast SSB transmission timing and resource information or indicate it through UE-specific RRC signaling.

[0126] NR can perform beam-based transmission and reception operations. If the reception performance of the current serving beam degrades, a process called beam failure recovery (BFR) can be used to find a new beam.

[0127] Since BFR is not a process for declaring an error / failure in the link between the network and the terminal, it can be assumed that the connection with the current serving cell is maintained even when the BFR process is performed. During the BFR process, measurements are performed on different beams set by the network (a beam can be expressed as a CSI-RS port or an SSB (synchronization signal block) index, etc.) and the best beam for the terminal is selected. The terminal can proceed with the BFR process by performing the RACH process associated with the beam with the best measurement result.

[0128] Now, we will describe the Transmission Configuration Indicator (TCI) state. The TCI state can be set for each core set of the control channel, and parameters for determining the terminal's receive (Rx) beam can be determined based on the TCI state.

[0129] For each downlink bandwidth portion (DL BWP) of a serving cell, a terminal may be configured with up to three core sets. Additionally, for each core set, the terminal may be provided with the following information:

[0130] 1) Coreset index p (e.g., one from 0 to 11, where the index of each coreset can be uniquely determined among the BWPs of a serving cell),

[0131] 2) PDCCH DM-RS scrambling sequence initialization value,

[0132] 3) Interval in the time domain of the core set (can be given in symbol units),

[0133] 4) A set of resource blocks,

[0134] 5) CCE-to-REG mapping parameters,

[0135] 6) Antenna port quasi co-location (QCL) information indicating quasi co-location (QCL) information of DM-RS antenna ports for PDCCH reception in each core set (from a set of antenna port quasi co-locations provided by a higher layer parameter called 'TCI-State');

[0136] 7) Indicating the presence or absence of a transmission configuration indication (TCI) field for a specific DCI format transmitted by PDCCH in the core set, etc.

[0137] Let's explain QCL. If the characteristics of the channel through which a symbol on one antenna port is transmitted can be inferred from the characteristics of the channel through which a symbol on another antenna port is transmitted, then the two antenna ports are said to be in quasi-co-location (QCL). For example, if two signals (A and B) are transmitted from the same transmit antenna array with identical / similar spatial filters applied, the two signals may experience identical / similar channel conditions. From the receiver's perspective, if one of the two signals is received, the channel characteristics of the received signal can be used to detect the other signal.

[0138] In this sense, the fact that A and B are QCL may mean that A and B experienced similar channel conditions, and thus, the channel information estimated to detect A is also useful for detecting B. Here, the channel conditions may be defined by, for example, Doppler shift, Doppler spread, average delay, delay spread, spatial reception parameters, etc.

[0139] The 'TCI-State' parameter associates one or two downlink reference signals with a corresponding QCL type (there are QCL types A, B, C, and D, see Table 4).

[0140] [Table 4]

[0141]

[0142] Each 'TCI-State' may include parameters for establishing a quasi-colocation (QCL) relationship between one or two downlink reference signals and a DM-RS port of a PDSCH (or PDCCH), or a CSI-RS port of a CSI-RS resource.

[0143] Meanwhile, in each DL BWP configured for a terminal in a serving cell, the terminal may be provided with up to 10 search space sets. For each search space set, the terminal may be provided with at least one of the following pieces of information:

[0144] 1) Search space set index s (0≤s<40), 2) Association between core set P and search space set s, 3) PDCCH monitoring period and PDCCH monitoring offset (slot unit), 4) PDCCH monitoring pattern within a slot (e.g., indicating the first symbol of the core set within a slot 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, etc.

[0145] In NR, core set #0 can be configured by PBCH (or terminal-specific signaling for handover, PSCell configuration, or BWP configuration). The search space (SS) set #0 configured by PBCH can have different monitoring offsets (e.g., slot offset, symbol offset) for each associated SSB. This may be necessary to minimize the search space occasions that the terminal must monitor. Alternatively, it may also be necessary to provide a beam sweeping control / data area that can transmit control / data for each beam so that communication with the terminal can be continuously performed in a situation where the best beam of the terminal dynamically changes.

[0146] Figure 11 illustrates physical channels and general signal transmission.

[0147] Referring to Figure 11, in a wireless communication system, a terminal receives information from a base station via the downlink (DL), and the terminal transmits information to the base station via the uplink (UL). The information transmitted and received between the base station and the terminal includes data and various control information, and various physical channels exist depending on the type and purpose of the information they transmit and receive.

[0148] When a terminal is powered on again from a powered-off state or newly enters a cell, it performs an initial cell search operation, such as synchronizing with the base station (S11). To this end, the terminal receives the PSCH (Primary Synchronization Channel) and SSCH (Secondary Synchronization Channel) from the base station to synchronize with the base station and obtain information such as the cell ID (cell identity). In addition, the terminal can obtain broadcast information within the cell by receiving the PBCH (Physical Broadcast Channel) from the base station. In addition, the terminal can receive the DL RS (Downlink Reference Signal) during the initial cell search phase to check the downlink channel status.

[0149] (Initial) cell search can be defined as a procedure in which a terminal acquires time and frequency synchronization with a cell and detects the cell ID of the cell. Cell search can be based on the primary synchronization signal and secondary synchronization signal of the cell, and the PBCH DMRS.

[0150] A terminal that has completed initial cell search can obtain more specific system information by receiving a PDCCH (Physical Downlink Control Channel) and a corresponding PDSCH (Physical Downlink Control Channel) (S12).

[0151] Thereafter, the terminal can perform a random access procedure (Random Access Procedure) to complete connection to the base station (S13-S16). Specifically, the terminal can transmit a preamble through a Physical Random Access Channel (PRACH) (S13) and receive a Random Access Response (RAR) for the preamble through a PDCCH and a corresponding PDSCH (S14). Thereafter, the terminal can transmit a Physical Uplink Shared Channel (PUSCH) using scheduling information in the RAR (S15) and perform a contention resolution procedure (Contention Resolution Procedure) such as a PDCCH and a corresponding PDSCH (which can be considered a process of receiving a contention resolution message) (S16).

[0152] A terminal that has performed the above-described procedure can then perform PDCCH / PDSCH reception (S17) and PUSCH / PUCCH (Physical Uplink Control Channel) transmission (S18) as general uplink / downlink signal transmission procedures. Control information that the terminal transmits to the base station is referred to as UCI (Uplink Control Information). UCI includes HARQ ACK / NACK (Hybrid Automatic Repeat and reQuest Acknowledgement / Negative-ACK), SR (Scheduling Request), CSI (Channel State Information), etc. CSI includes CQI (Channel Quality Indicator), PMI (Precoding Matrix Indicator), RI (Rank Indication), etc. UCI is generally transmitted through PUCCH, but can be transmitted through PUSCH when control information and data must be transmitted simultaneously. In addition, the terminal can aperiodically transmit UCI through PUSCH according to a request / instruction of the network.

[0153] To enable reasonable battery consumption when BA (bandwidth adaptation) is configured, only one uplink BWP and one downlink BWP, or only one downlink / uplink BWP pair, for each uplink carrier can be activated at a time within an active serving cell, while all other BWPs configured in the UE are deactivated. In deactivated BWPs, the UE does not monitor the PDCCH and does not transmit on the PUCCH, PRACH, and UL-SCH.

[0154] For BA, the receive and transmit bandwidth of the terminal need not be as wide as the cell bandwidth and can be adjusted: the width can be commanded to change (e.g., shrinking during periods of low activity to save power), the location in the frequency domain can be moved (e.g., to increase scheduling flexibility), and the subcarrier spacing can be commanded to change (e.g., to allow different services). A subset of the total cell bandwidth of a cell is referred to as a bandwidth part (BWP), and a BA is obtained by setting BWP(s) to the terminal and notifying the terminal which of the set BWPs is currently active. Once a BA is set, the terminal only needs to monitor the PDCCH on one active BWP. That is, there is no need to monitor the PDCCH on the entire downlink frequency of the cell. A BWP inactive timer (independent of the DRX inactive timer described above) is used to switch an active BWP to a default BWP: the timer is restarted upon successful PDCCH decoding, and a switch to the default BWP occurs when the timer expires.

[0155] Below, we describe the integrated access and backhaul link (IAB). For convenience, the proposed approach is based on the new RAT (NR) system. However, the scope of the proposed approach can be expanded to include other systems, such as 3GPP LTE / LTE-A systems, in addition to NR systems.

[0156] One potential technology that aims to enable future cellular network deployment scenarios and applications is support for wireless backhaul and relay links, enabling flexible and very dense deployment of NR cells without the need to proportionally densify the transport network.

[0157] The expected availability of greater bandwidth in NR compared to LTE (e.g., in the mmWave spectrum), along with the native deployment of massive MIMO or multi-beam systems, creates opportunities for the development and deployment of integrated access and backhaul links. This allows for easier deployment of dense networks of self-backhauled NR cells in a more integrated manner by establishing multiple control and data channels / procedures defined to provide connectivity or access to terminals. Such systems are referred to as integrated access and backhaul links (IAB).

[0158] In this disclosure, the following are defined:

[0159] - AC(x): Access link between node(x) and terminal(s).

[0160] - BH(xy): Backhaul link between node(x) and node(y).

[0161] At this time, the node may refer to a DgNB (donor gNB) or a relay node (RN). Here, the DgNB or donor node may be a gNB that provides a function to support backhaul for IAB nodes.

[0162] When relay node 1 and relay node 2 exist, and relay node 1 is connected to relay node 2 via a backhaul link and relays data transmitted and received to 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.

[0163] Technical features individually described in a single drawing in this specification may be implemented individually or simultaneously.

[0164] The following drawings are intended to illustrate specific examples of the present specification. The names of specific devices and the names of specific signals, messages, and fields depicted in the drawings are provided for illustrative purposes only, and the technical features of this specification are not limited to the specific names used in the drawings.

[0165] <PUSCH 반복(repetitions)>

[0166] PUSCH repetition types A and B were introduced in the standard specifications (e.g., NR Rel-15 / 16). Transmission is performed as follows depending on the PUSCH repetition type.

[0167] 1) PUSCH repetition type A

[0168] Figure 12 is an example of PUSCH repetition type A.

[0169] Referring to FIG. 12, PUSCH repetition type A is a slot-based PUSCH repetition transmission, and repetition is performed with the same PUSCH transmission start symbol position and PUSCH transmission symbol length for each slot, as illustrated in FIG. 12. At this time, if an invalid symbol that cannot be used for PUSCH transmission exists among the symbol resources constituting a specific PUSCH repetition, the transmission of the corresponding PUSCH repetition is dropped and not performed. For example, when a total of four PUSCH repetition transmissions of Rep0, Rep1, Rep2, and Rep3 are performed in slots N, N+1, N+2, and N+3 (one PUSCH repetition is transmitted in each slot), if an invalid symbol is included in the symbol resources constituting Rep1, the transmission of Rep1 is dropped, and only the transmissions of Rep0, Rep2, and Rep3 are performed. Therefore, the actual number of repetitions performed may be less than the set number of repetitions.

[0170] For PUSCH repetition type A, frequency hopping can be configured for the UE by upper layer parameters. One of two frequency hopping modes can be configured.

[0171] i) Frequency hopping within a slot is applicable to single slot and multi-slot PUSCH transmission.

[0172] ii) Inter-slot frequency hopping is applicable to multi-slot PUSCH transmission.

[0173] 2) PUSCH repetition type B

[0174] Figure 13 is an example of PUSCH repetition type B.

[0175] Referring to Fig. 13, PUSCH repetition type B is repeated in units of the symbol length in which the actual PUSCH is transmitted. For example, as in (a) of Fig. 13, when the PUSCH is transmitted through 10 symbols, PUSCH repetition is performed in units of 10 consecutive symbols. At this time, the repetition that determines the PUSCH repetition transmission time resource without considering slot boundaries, invalid symbols, etc. is called nominal repetition. In Fig. 13 (a), three nominal repetitions (N0, N 1, An example is shown where N2 is set.

[0176] However, in the case of actual PUSCH repetition, a single PUSCH cannot be transmitted while including a slot boundary. That is, if a nominal PUSCH transmission includes a slot boundary (e.g., N0, N2 in (a) of FIG. 13), two actual repetitions are performed with the slot boundary as the boundary, as in (b) of FIG. 13. For example, a nominal repetition N0 is performed with two actual repetitions, such as A0, A1, with the slot boundary as the boundary.

[0177] Additionally, a single PUSCH transmission can only be performed using consecutive symbols. If an invalid symbol exists in the time resource where a PUSCH repetition should be transmitted, the actual repetition is formed using consecutive symbols with the invalid symbol as the boundary. For example, if symbols #0 to #9 constitute a nominal repetition and symbols #3 to #5 are invalid symbols, symbols #0 to #2 and symbols #6 to #9, excluding the invalid symbol, each constitute an actual repetition.

[0178] Invalid symbols may include the following:

[0179] i) Downlink symbol set by semi-static TDD UL-DL setting,

[0180] ii) an invalid symbol pattern set by RRC (which may be set by the invalid symbol pattern indicator);

[0181] iii) SSB symbol set by SIB1, SSB symbol set by 'ServngCellConfigCommon',

[0182] iv) Symbol for PDCCH for SIB1,

[0183] v) Invalid symbol for DL-UL switching set by RRC.

[0184] If a symbol that cannot be used for PUSCH transmission (e.g., a DL symbol indicated by DCI format 2_0) is included within one actual repetition resource, the corresponding actual repetition transmission is dropped and not performed.

[0185] Now, we describe full duplex operation.

[0186] 5G is giving rise to new service types, such as extended reality (XR), AI-based services, and self-driving cars. These services are characterized by dynamic traffic in both downlink (DL) and uplink (UL) directions, and the requirement for low latency in the transmission of traffic (e.g., packets). To support these diverse new use cases, 5G services will experience an explosive increase in traffic.

[0187] Existing semi-static or dynamic TDD UL / DL configurations suffer from transmission delays and interference between operators. Existing FDD schemes also face limitations in efficient frequency resource utilization in the DL / UL directions. Therefore, the introduction of full-duplex operation within a single carrier is being discussed to achieve low latency and efficient resource utilization in NR.

[0188] Figure 14 shows examples of how to apply full duplex within a carrier.

[0189] Referring to FIG. 14, in the full duplex method, subband-wise full duplex (hereinafter, referred to as subband full duplex or SBFD) as in (a) of FIG. 14 and spectrum-sharing full duplex (hereinafter, referred to as SSFD) as in (b) of FIG. 14 can be considered.

[0190] In the case of SBFD, DL and UL transmission and reception are performed through different frequency resources within the same carrier (e.g., carrier #0). That is, different frequency resources are used for DL ​​and UL for the same time resource.

[0191] In SSFD, DL and UL transmission and reception are performed through the same frequency resources or overlapping frequency resources within the same carrier (e.g., carrier #0). That is, DL and UL can use the same or overlapping frequency resources for the same time resource.

[0192] This full-duplex (FD) operation can also be combined with existing half-duplex (HD) operation. For example, among the time resources used for existing half-duplex-based TDD operation, some of the time resources can be used for full-duplex operation. For example, SBFD or SSFD operation can be performed on the time resources performing full-duplex operation.

[0193] Figure 15 shows examples where time resources operating in HD (half duplex) and time resources operating in FD (full duplex), such as SBFD or SSFD, coexist.

[0194] In (a) of Fig. 15, some time resources operating in SBFD are indicated as SBFD, and time resources operating in half-duplex are indicated as HD. In (b) of Fig. 15, some time resources operating in SSFD are indicated as SSFD, and time resources operating in half-duplex are indicated as HD. The unit of the time resource may be, for example, a slot or a symbol.

[0195] In a time resource operating under SBFD, 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 for both DL and UL and remains empty. The guard subband may also be referred to by other terms, such as guard frequency resources or guard subcarrier(s).

[0196] In a time resource operating in SSFD, the entire frequency resource can be used for both DL and UL. Alternatively, to reduce the impact of interference (which may be referred to as adjacent carrier interference (ACI)) from other adjacent carriers, some frequency resources at one or both ends of the carrier can be left unused for DL ​​and / or UL. That is, one or both ends of the carrier can be used as guard bands (guard subbands) that are not used for both DL and UL. Alternatively, to reduce the impact of ACI on UL reception, one or both ends of the carrier can be used only for DL ​​transmission.

[0197] In this disclosure, a slot resource operating in half-duplex is referred to as an HD slot, and a slot resource operating in SBFD and a slot resource operating in SSFD are referred to as an SBFD slot (SBFD slot) and an SSFD slot (SSFD slot), respectively. In addition, an SSFD slot and an SSFD slot are collectively referred to as an FD slot.

[0198] In the present disclosure, in a time resource operating as FD, a frequency resource operating as DL among the entire frequency resources is conveniently called a DL subband, and a frequency resource operating as UL may also be called a UL subband.

[0199] In full-duplex operation, both the base station and the terminal can perform full-duplex operation. That is, both the base station and the terminal can simultaneously transmit and receive DL and UL using the same or different frequency resources in the same time resource.

[0200] Alternatively, only the base station can perform full-duplex operation, while the terminals can perform half-duplex operation. The base station can simultaneously transmit and receive DL and UL signals using the same or different frequency resources in the same time resource, but the terminals perform only DL reception or UL transmission in specific time resources. In this case, the base station performs full-duplex operation by performing DL transmission and UL reception with different terminals at the same time.

[0201] The present disclosure assumes that the base station performs / supports full duplex operation, while the terminal performs / supports half duplex operation. However, the present disclosure can also be applied to cases where both the base station and the terminal perform / support full duplex operation.

[0202] Based on this discussion, the present disclosure proposes a PUSCH transmission method of a terminal when one PUSCH transmission includes both SBFD symbols and non-SBFD symbols during intra-carrier full duplex operation.

[0203] In the following, the term "network" may be interpreted as gNB or CU / DU. Furthermore, the term "terminal (UE)" may be interpreted as MT (mobile terminal, mobile termination) of an IAB node or NCR-MT (MT of a network-controlled repeater).

[0204] A. Characteristics of DL / UL time / frequency resources for SBFD and SSFD operations

[0205] A cell (base station) can perform both DL transmission and UL reception in the same time resource in a FD manner, such as SBFD or SSFD. For example, the base station can perform HD operation in the first time resource and FD operation in the second time resource (which may be any time resource other than the first time resource).

[0206] In the first time resource performing the HD operation, the DL operation or the UL operation is performed across the entire frequency resources that constitute the entire system bandwidth. Within the first time resource performing the HD operation, the network performs the DL operation through the 1-1 time resource and the UL operation through the 1-2 time resource. At this time, the 1-1 time resource and the 1-2 time resource do not overlap with each other.

[0207] In the second time resource performing the FD operation, the network performs the DL operation through all or part of the frequency resources (first frequency resources) among the frequency resources constituting the system band of the cell, and performs the UL operation through all or part of the frequency resources (second frequency resources).

[0208] Figure 16 shows examples of a first time resource, a second time resource, a first frequency resource, and a second frequency resource.

[0209] Referring to (a) of FIG. 16, in the first time resource (indicated by A), the device operates in half-duplex. In the second time resource (indicated by B), the device may operate in, for example, SBFD. The resource indicated by DL in the first time resource corresponds to the aforementioned 1-1 time resource, and the resource indicated by UL corresponds to the aforementioned 1-2 time resource.

[0210] Referring to (b) of Fig. 16, the frequency resource operating as DL in the second time resource corresponds to the first frequency resource described above, and the frequency resource operating as UL corresponds to the second frequency resource described above.

[0211] Figure 17 illustrates another example of a first time resource, a second time resource, a first frequency resource, and a second frequency resource.

[0212] Referring to (a) of FIG. 17, in the first time resource (indicated by A), the device operates in half-duplex. In the second time resource (indicated by B), for example, it may operate in SSFD. The resource indicated by DL in the first time resource corresponds to the aforementioned 1-1 time resource, and the resource indicated by UL corresponds to the aforementioned 1-2 time resource.

[0213] Referring to (b) of Fig. 17, the frequency resources operating as DL and DL+UL in the second time resource correspond to the first frequency resource described above, and the frequency resources operating as DL+UL correspond to the second frequency resource described above.

[0214] The first frequency resource and / or the second frequency resource may have all or some of the following characteristics:

[0215] 1) When performing SBFD operation, the first frequency resource and the second frequency resource do not overlap with each other. This is to ensure that DL and UL operations are performed through different frequency resources. At this time, there may be frequency resources that do not correspond to either the first or second frequency resources, and such frequency resources are called guard subbands or guard frequency resources. Such guard frequency resources may be necessary to reduce interference between DL transmission and UL reception. The guard frequency resource may be located between the first and second frequency resources.

[0216] 2) When performing SSFD operation, the first frequency resource and the second frequency resource may overlap. In this case, there may be frequency resources that do not correspond to either the first frequency resource or the second frequency resource, and such frequency resources are called guard subbands or guard frequency resources. Such guard frequency resources may be necessary to reduce interference between DL transmissions on adjacent carriers and / or between DL transmissions and UL reception on adjacent carriers.

[0217] 3) When performing the SBFD operation, the second frequency resource may be configured with continuous frequency resources, and the first frequency resource may be configured with non-contiguous frequency resources. In this case, the first frequency resource may be configured with multiple (for example, two) non-contiguous sets, and each set may be configured with continuous frequency resources. This is to reduce interference of DL transmission on adjacent carriers to UL resources by positioning the second frequency resource used for UL at the center of the frequency resources constituting the cell. Conversely, the first frequency resource may be configured with continuous frequency resources, and the second frequency resource may be configured with non-contiguous frequency resources. In this case, the second frequency resource may be configured with multiple (for example, two) non-contiguous sets, and each set may be configured with continuous frequency resources. This is to reduce interference of DL transmission on UL resources on adjacent carriers by positioning the second frequency resource used for DL ​​at the center of the frequency resources constituting the cell.

[0218] 4) When performing SSFD operation, the second frequency resource may be configured with a portion of the frequency resources of the first frequency resource. In this case, the second frequency resource may be configured with X PRBs (physical resource blocks) less than the first frequency resource for one or both edge portions of the carrier. This is to reduce interference between DL transmission on adjacent carriers and UL reception.

[0219] The network can determine / judge the 'first time resource' and 'second time resource', and the 'first frequency resource' and 'second frequency resource' as described above, and provide all or part of the corresponding information to the terminal.

[0220] The terminal can determine information about time resources (hereinafter referred to as SBFD symbols) that operate as SBFD (and / or SSFD) for the FD (SBFD and / or SSFD) operation of the cell. For this purpose, information about SBFD symbols can be set to the terminal from the network.

[0221] When a specific time resource is configured as a time resource operating in SBFD (SBFD symbol), both DL and UL resources can exist in 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 only perform DL transmission. In SBFD resources, DL transmission occurs only within the DL subband. Therefore, even if there is no UL signal transmitted in the UL subband, DL transmission can only be performed within the DL subband.

[0222] In this case, even if a specific time resource is determined to be an SBFD symbol, if there is no UL transmission to be received by the base station, it may be considered to perform DL transmission not only on the DL subband but also outside the DL subband to improve DL throughput. In other words, it may be considered to perform DL transmission over the entire bandwidth.

[0223] That is, a fallback to TDD operation that performs DL or UL operation over the entire band, rather than SBFD operation over DL / UL subbands, can be considered for resources judged as SBFD symbols.

[0224] In resources not identified by the SBFD symbol, the terminal can perform TDD operation (half-duplex operation) like a conventional terminal. That is, it can perform only DL or UL operation using the entire frequency resources of the cell.

[0225] A terminal can receive SBFD symbol information from the network. Based on this, it can determine whether a specific symbol is an SBFD symbol or a non-SBFD symbol.

[0226] i) If the terminal determines that a specific symbol is a non-SBFD symbol, it can perform a legacy operation on the symbol (or determines that a legacy operation is to be performed).

[0227] ii) If the terminal determines that a specific symbol is an SBFD symbol, it determines that the symbol is a symbol that can perform SBFD operation from the cell perspective.

[0228] The terminal may not receive configuration information for SBFD symbols from the network. In this case, i) the terminal may determine all symbols as non-SBFD symbols. Therefore, the terminal may operate as in legacy TDD for all symbols.

[0229] Or ii) if the terminal does not receive configuration information for SBFD symbols from the network, the terminal may determine all symbols as SBFD symbols.

[0230] If the terminal determines that a specific symbol is an SBFD symbol, i) in general, the terminal can perform DL reception within the DL subband and UL transmission within the UL subband in the time resource where the cell is determined to operate in SBFD. ii) Additionally, the base station can consider performing only DL transmission or UL reception in the time resource where the cell is determined to operate in SBFD, or performing DL transmission or UL reception over the entire band (capable of receiving DL or UL scheduling) as needed.

[0231] The terminal can determine the UL subband and DL subband based on the network settings.

[0232] i) The terminal receives information about UL subbands and DL subbands from the network, and can determine frequency resources constituting the UL subbands and DL subbands from this.

[0233] ii) Or, the terminal can receive only the information about the UL subband from the network and determine the frequency resources constituting the UL subband from this. In this case, the remaining frequency resources, excluding the frequency resources set / determined as the UL subband within the frequency resources constituting the system BW, can be determined as DL subbands. Additionally, if the terminal is configured with the frequency resources constituting the guard subband, the remaining frequency resources, excluding the frequency resources set / determined as the UL subband and the guard subband within the frequency resources constituting the system BW, can be determined as DL subbands.

[0234] iii) Alternatively, the terminal may receive only information about the DL subband from the network and determine the frequency resources constituting the UL subband from this. In this case, the remaining frequency resources, excluding the frequency resources set / determined as the DL subband within the frequency resources constituting the system band, may be determined as the UL subband. Additionally, if the terminal receives frequency resources constituting the guard subband, the remaining frequency resources, excluding the frequency resources set / determined as the DL subband and the guard subband within the frequency resources constituting the system band, may be determined as the UL subband.

[0235] In the present disclosure, the time resource operating in SBFD or the SBFD symbol may refer to the aforementioned "second time resource." In addition, the time resource operating in TDD, the time resource operating in HD, the TDD symbol, or the HD symbol in the present disclosure may refer to the aforementioned "first time resource."

[0236] 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."

[0237] Based on the above, the present disclosure describes a PUSCH transmission method of a terminal when one PUSCH transmission includes both SBFD symbols and non-SBFD symbols during intra-carrier full duplex operation.

[0238] Although the contents of the present disclosure are described assuming transmission of PUSCH (including TBoMS), the contents of the present disclosure can also be applied to reception of PDSCH and transmission of PUCCH.

[0239] The present disclosure assumes SBFD operation, where a cell performs DL and UL simultaneously using different frequency resources (subbands) within the same time resource. However, the contents of the present disclosure can also be applied to a cell performing SSFD operation.

[0240] Figure 18 illustrates a case where symbol resources allocated for PUSCH transmission within a slot include both SBFD symbols and non-SBFD symbols.

[0241] Referring to FIG. 18, in case of PUSCH repetition type A and / or TBoMS transmission, PUSCH / TBoMS transmission within one slot consists of consecutive symbol resources within the slot.

[0242] When both non-SBFD symbols and SBFD symbols can exist in the symbols within a slot, symbol resources allocated for PUSCH (including TBoMS) transmission within the slot can include both SBFD symbols and non-SBFD symbols, as shown in FIG. 18.

[0243] For PUSCH repetition type B, a nominal repetition consists of consecutive symbol resources within a slot or within two adjacent slots. If a nominal repetition includes a slot boundary, the actual repetition is divided by the slot boundary. Therefore, a real repetition consists of consecutive symbol resources within a slot.

[0244] Figure 19 illustrates a case where symbol resources allocated for PUSCH transmission in multiple slots include both SBFD symbols and non-SBFD symbols.

[0245] Referring to Figure 19, slot #N contains both SBFD symbols and non-SBFD symbols. Slot #N+1 contains only SBFD symbols.

[0246] In such cases, there may be cases where the symbol resources allocated / configured for PUSCH transmission include both SBFD symbols and non-SBFD symbols.

[0247] PUSCH transmissions in SBFD symbols and PUSCH transmissions in non-SBFD symbols may not be identical in several aspects.

[0248] In an SBFD symbol, if the PRB resources allocated for PUSCH transmission are not all included within the UL subband, the number of PRBs used in each of the PUSCH transmission in the SBFD symbol and the PUSCH transmission in the non-SBFD symbol may be different.

[0249] If the number of PRBs used in PUSCH transmission in an SBFD symbol is different from that used in a non-SBFD symbol (or there may be other reasons besides the number of PRBs being different), the UL transmission power (Tx power) of the UE in the SBFD symbol and the non-SBFD symbol may be different.

[0250] From the base station perspective, the configuration of antenna / panel / RF (antenna / panel / RF) for UL reception in SBFD symbols and non-SBFD symbols is not the same, so the channel, UL reception beam (Rx beam), etc. in the two resources may be different.

[0251] When performing PUSCH transmission using both non-SBFD symbols and SBFD symbols in the same transmission occasion, the UE may need to apply different PUSCH transmission methods depending on the symbol type (i.e., whether it is an SBFD symbol or a non-SBFD symbol). And / or the base station may need to apply different PUSCH reception methods depending on the symbol type (SBFD / non-SBFD symbol).

[0252] Therefore, several problems may arise when a terminal performs a single PUSCH transmission within a slot using both non-SBFD symbols and SBFD symbols.

[0253] Considering these problems, the present disclosure proposes a PUSCH transmission method of a terminal when one PUSCH transmission is configured to include both SBFD symbols and non-SBFD symbols.

[0254] Although the present disclosure describes a transmission method according to a transmission symbol configuration of one PUSCH transmission (transmission opportunity), it can also be applied when a PUSCH is transmitted repeatedly K times.

[0255] Although the contents of the present disclosure are described assuming transmission of PUSCH (including TBoMS), the contents of the present disclosure can also be applied to reception of PDSCH and transmission of PUCCH.

[0256] <A. 슬롯 내에서의 PUSCH / TBoMS 전송>

[0257] We propose a PUSCH transmission method for a UE when a single PUSCH transmission within a slot includes both SBFD and non-SBFD symbols. A single PUSCH transmission within a slot may include a TBoMS transmission within the slot. This section can be applied to PUSCH repetition transmissions according to PUSCH repetition type A.

[0258] When a PUSCH transmission includes both SBFD symbols and non-SBFD symbols (if configured to include them), the UE may apply one of the following methods for the PUSCH transmission. Alternatively, the UE may apply different methods depending on the instructions / conditions.

[0259] 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 slot, the terminal does not perform PUSCH transmission in that slot.

[0260] Method 2. If the L symbols allocated in the time domain for PUSCH transmission within a specific slot include both non-SBFD symbols and SBFD symbols, and if all PRBs (physical resource blocks) allocated for PUSCH transmission in the frequency domain are included in the PRB resources constituting the UL subband, the UE performs PUSCH transmission using the L symbols in the slot. Otherwise, the UE does not perform PUSCH transmission in the slot.

[0261] Method 3. If the L symbols allocated in the time domain for PUSCH transmission within a specific slot include both non-SBFD symbols and SBFD symbols, the PUSCH transmission is performed using the L symbols in the slot by using the PRB (or RBG) resources included in the UL subband among the PRB (or RBG) resources allocated for PUSCH transmission in the frequency domain. That is, the PUSCH transmission is performed using the L symbols in the slot by using the PRB (or RBG) resources included in the UL subband not only in the SBFD symbol but also in the non-SBFD symbol.

[0262] Method 4. If the L symbols allocated in the time domain for PUSCH transmission within a specific slot include both non-SBFD symbols and SBFD symbols, the terminal assumes (or determines) that all of the L symbols are SBFD symbols, and based on this, performs PUSCH transmission for the L symbols in the slot.

[0263] Method 5. The terminal can perform PUSCH transmission only using symbol resources with a specific symbol type as follows.

[0264] Action 5-1: If a specific slot contains at least one non-SBFD symbol, the terminal does not perform PUSCH transmission in that slot. In this case, if all symbols in the slot consist of SBFD symbols, the terminal performs PUSCH transmission in that slot.

[0265] Alternatively, if the symbol resources allocated for PUSCH transmission within a specific slot include at least one non-SBFD symbol, the terminal does not perform PUSCH transmission in that slot. In this case, if all symbol resources allocated for PUSCH transmission within a specific slot are composed of SBFD symbols, the terminal performs PUSCH transmission in that slot.

[0266] Action 5-2: If at least one SBFD symbol is included in a specific slot, the terminal does not perform a PUSCH transmission in that slot. In this case, if all symbols in the slot are composed of non-SBFD symbols, the terminal performs a PUSCH transmission in that slot.

[0267] Alternatively, if the symbol resources allocated for PUSCH transmission within a specific slot include at least one SBFD symbol, the terminal does not perform PUSCH transmission in that slot. In this case, if all symbol resources allocated for PUSCH transmission within a specific slot are composed of non-SBFD symbols, the terminal performs PUSCH transmission in that slot.

[0268] In this case, the terminal can perform operation 5-1 or operation 5-2 according to the following criteria / conditions / instructions.

[0269] Option 1. If all symbols within the first slot in which the PUSCH is indicated to be transmitted are composed of SBFD symbols or if all symbols allocated for PUSCH transmission within the first slot in which the PUSCH is indicated to be transmitted are composed of SBFD symbols, the terminal applies operation 5-1 above. Otherwise, the terminal applies operation 5-2 above.

[0270] Option 2. If all symbols within the first slot in which the PUSCH is indicated to be transmitted are composed of non-SBFD symbols or if all symbols allocated for PUSCH transmission within the first slot in which the PUSCH is indicated to be transmitted are composed of non-SBFD symbols, the terminal applies operation 5-1 above. Otherwise, the terminal applies operation 5-2 above.

[0271] Option 3. The terminal applies either operation 5-1 or operation 5-2 via network instruction. To this end, the terminal may receive information about the symbol type (SBFD symbol or non-SBFD symbol) used for PUSCH transmission from the network via RRC, MAC-CE, DCI signaling, etc. For example, this may be indicated via DCI scheduling the PUSCH.

[0272] At this time, the applicability of Methods 2, 3, and 4 may vary depending on the implementation method of the base station or the transmission method of the terminal. Considering this, different methods may be applied based on instructions from the base station. For example, either Method 3 or Method 1 may be applied based on instructions from the base station. These instructions may be communicated to the terminal via RRC signaling, for example.

[0273] For PUSCH transmission in a specific slot, if PUSCH transmission is not performed by the above operation, the terminal may not include the slot constituting the PUSCH transmission in the available slots. That is, when the PUSCH is repeatedly transmitted K times, the slot in which the PUSCH is not transmitted for the above reason is not included in the K available slots for which PUSCH transmission is set.

[0274] At this time, if a PUSCH is not transmitted in a specific slot by an SBFD symbol and / or a non-SBFD symbol determined semi-statically by RRC and / or MAC-CE, the slot is not included in the available slots that constitute PUSCH transmission. On the other hand, for a slot in which a PUSCH is not transmitted in a specific slot by an SBFD symbol and / or a non-SBFD symbol determined through a DCI or a DCI that does not schedule a PUSCH, PUSCH transmission is not performed, but the slot may be included in the available slots that constitute PUSCH transmission.

[0275] <B. PUSCH 반복 타입 B의 명목상 / 실제 반복 전송>

[0276] For transmission of PUSCH repetition type B, a PUSCH transmission method of a terminal is proposed when symbol resources for one nominal repetition or actual repetition transmission include both SBFD symbols and non-SBFD symbols.

[0277] The terminal may apply at least one of the following methods for transmitting nominal or actual repetitions. Alternatively, the terminal may apply different methods depending on the instructions / conditions.

[0278] 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, hereinafter the same) symbols that constitute a specific nominal repetition, the terminal does not perform transmission of the corresponding nominal repetition.

[0279] Or, if both non-SBFD symbols and SBFD symbols are included in L' (L' is a natural number less than L, i.e., L'<= L, hereinafter the same) symbols constituting a specific actual repetition, the terminal does not perform transmission of the corresponding actual repetition.

[0280] Method 2. If the L symbols constituting a specific nominal repetition include both non-SBFD symbols and SBFD symbols, and if all PRBs allocated to PUSCH transmission are included in the PRB resources constituting the UL subband, the UE performs transmission of the nominal repetition using the L symbols. Otherwise, the UE does not perform transmission of the nominal repetition.

[0281] Alternatively, if the L' (<= L) symbols constituting a specific actual repetition include both non-SBFD symbols and SBFD symbols, and if all PRBs allocated to PUSCH transmission are included in the PRB resources constituting the UL subband, the terminal performs transmission of the actual repetition using the L' symbols. Otherwise, the terminal does not perform transmission of the actual repetition.

[0282] Method 3. If the L symbols constituting a specific nominal repetition include both non-SBFD symbols and SBFD symbols, the nominal repetition transmission is performed using the PRB (or RBG) resources included in the UL subband among the PRB (or RBG) resources allocated to PUSCH transmission. That is, the nominal repetition transmission is performed using the L symbols using the PRB (or RBG) resources included in the UL subband in both the SBFD symbol and the non-SBFD symbol.

[0283] Or, if both non-SBFD symbols and SBFD symbols are included in the L' (<= L) symbols constituting a specific actual repetition, the actual repetition transmission is performed using the L' symbols by using the PRB (or RBG) resources included in the UL subband among the PRB (or RBG) resources allocated to the PUSCH transmission. That is, the actual repetition transmission is performed using the L' symbols by using the PRB (or RBG) resources included in the UL subband in both the SBFD symbol and the non-SBFD symbol.

[0284] Method 4. If the L symbols that constitute a specific nominal repetition include both non-SBFD symbols and SBFD symbols, the terminal assumes (or determines) that all of the L symbols are SBFD symbols, and based on this, performs transmission of the nominal repetition using the L symbols.

[0285] Or, if the L' (<= L) symbols that constitute a specific actual repetition include both non-SBFD symbols and SBFD symbols, the terminal assumes (or determines) that all of the L' symbols are SBFD symbols, and based on this, performs transmission of the actual repetition using the L' symbols.

[0286] Method 5. Include SBFD or non-SBFD symbols in the invalid symbols used to determine the symbol resources that constitute the actual repetition. Therefore, these symbols are not included in the symbols that perform the actual repetition.

[0287] At this time, it can be determined whether a symbol among the SBFD symbol or the non-SBFD symbol is included in the invalid symbol as follows.

[0288] Alt 1. The terminal receives an indication from the base station as to which symbol, either an SBFD symbol or a non-SBFD symbol, is included in the invalid symbol. This indication may be provided via RRC, MAC-CE, and / or DCI signaling.

[0289] Alt 2. Depending on the indication of the type of symbol through which the PUSCH is transmitted, symbols that are not identical to the type are included in the invalid symbols. For example, the UE may be indicated by the network through DCI that schedules the PUSCH, the symbol type (SBFD symbol / non-SBFD symbol) of the symbol resources that perform the corresponding PUSCH transmission. That is, the UE may be indicated whether to perform the PUSCH transmission assuming the SBFD symbol or assuming the non-SBFD symbol. For example, if the UE is instructed to perform the PUSCH transmission assuming the SBFD symbol, the non-SBFD symbol is determined as an invalid symbol. On the other hand, if the UE is instructed to perform the PUSCH transmission assuming the non-SBFD symbol, the SBFD symbol is determined as an invalid symbol.

[0290] Alt 3. If the first symbol among the symbols that constitute a nominal repetition is a non-SBFD symbol, include the SBFD symbol in the invalid symbols. Additionally, if the first symbol among the symbols that constitute a nominal repetition is a SBFD symbol, include the non-SBFD symbol in the invalid symbols.

[0291] Alt 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, the SBFD symbol is included in the invalid symbols. Additionally, if the first symbol among the symbols constituting the first nominal repetition is an SBFD symbol, the non-SBFD symbol is included in the invalid symbols.

[0292] Additionally, for a specific nominal repetition, this method can be applied to perform PUSCH transmission in cases where not all PRBs allocated to PUSCH transmission are included in the PRB resources constituting the UL subband.

[0293] Method 6. If the L symbols that constitute a specific nominal repetition include both non-SBFD symbols and SBFD symbols, the actual repetition is divided based on the boundary between the SBFD symbol resources and the non-SBFD symbol resources.

[0294] For example, among the four symbols that constitute Nominal Rep2 in Fig. 19, the first and second symbols are SBFD symbols, and the third and fourth symbols are non-SBFD symbols. In this case, the first and second symbols constitute one actual repetition, and the third and fourth symbols constitute another actual repetition, based on the boundary between the SBFD symbol resource and the non-SBFD symbol resource. This will be described in detail with reference to Fig. 21.

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

[0296] At this time, the applicability of the above method may vary depending on the implementation method of the base station or the transmission method of the terminal. Considering this, different methods may be applied based on instructions from the base station. For example, either Method 3 or Method 1 may be applied based on instructions from the base station. These instructions may be communicated to the terminal via RRC signaling, for example.

[0297] Figure 20 illustrates an operation method of a terminal in a wireless communication system.

[0298] Referring to FIG. 20, the terminal receives information used to set parameters of an uplink data channel applicable to a specific frequency band (S201).

[0299] The above information may be, for example, a PUSCH-Config information element used to set terminal-specific PUSCH parameters applicable to a particular BWP.

[0300] The terminal performs repetitive transmission of the uplink data channel based on the above information. However, in the repetitive transmission, if both full duplex (FD) time resources and half duplex (HD) time resources are included in the time resources set for transmission of a specific uplink data channel, the terminal skips / drops transmission of the specific uplink data channel (S202). That is, transmission of the specific uplink data channel is dropped or transmission of the specific uplink data channel is not performed.

[0301] Depending on the embodiment, the terminal may further receive a repetition type indicator indicating the type of repetitive transmission of the uplink data channel.

[0302] For example, a UE may be provided with an indicator (e.g., 'pusch-RepTypeIndicatorDCI-0-1', 'pusch-RepTypeIndicatorDCI-0-2') indicating the type of PUSCH repetition transmission via an RRC message / information element ('PUSCH-Config') used to configure UE-specific PUSCH parameters applicable to a specific bandwidth part (BWP).

[0303] For example, 'pusch-RepTypeIndicatorDCI-0-1', 'pusch-RepTypeIndicatorDCI-0-2' indicate (indicate) whether the UE follows PUSCH repetition type A operation or PUSCH repetition type B operation for PUSCH scheduled by DCI format 0_1, DCI format 0_2 and / or configured grant (CG) transmission associated with activating DCI format 0_1 / 0_2, respectively. 'pusch-RepTypeIndicatorDCI-0-1', 'pusch-RepTypeIndicatorDCI-0-2' activates PUSCH repetition type A or PUSCH repetition type B, respectively. 'pusch-RepTypeIndicatorDCI-0-1' is applied to DCI format 0_1 ​​and 'pusch-RepTypeIndicatorDCI-0-2' is applied to DCI format 0_2.

[0304] The terminal can determine the repetition transmission type of the uplink data channel as one of the first repetition type and the second repetition type based on the repetition type indicator.

[0305] For example, the first repetition type may be a physical uplink shared channel (PUSCH) repetition type A, which is configured to perform repeated transmission of the uplink data channel with the same transmission start symbol and transmission symbol length in each slot. PUSCH repetition type A may include only one PUSCH repetition in one slot.

[0306] And, the second repetition type may be PUSCH repetition type B, which is configured to perform repeated transmission of the uplink data channel in units of transmission symbol length. In PUSCH repetition type B, multiple PUSCH repetitions may be included in one slot. When repeatedly transmitting a PUSCH with PUSCH repetition type B, if a slot boundary or an invalid symbol is included in symbols of the transmission symbol length, two actual repetition transmissions are performed with the slot boundary or the invalid symbol as the boundary.

[0307] As for PUSCH repetition type A and PUSCH repetition type B, they have already been described above with reference to FIGS. 12 and 13.

[0308] The terminal can perform repeated transmission of the uplink data channel based on the determined repetition type.

[0309] At this time, if both full duplex (FD) time resources and half duplex (HD) time resources are included in the slot for transmission of the uplink data channel, the transmission operation of the uplink data channel can be performed differently depending on the determined repetition type.

[0310] For example, the FD time resource may be an SBFD symbol that enables the terminal to operate in SBFD (subband-wise full duplex), and the HD time resource may be a non-SBFD symbol.

[0311] More specifically, when repeatedly transmitting the uplink data channel (PUSCH) with the first repetition type (PUSCH repetition type A), if both the FD time resource and the HD time resource are included for transmission of the uplink data channel within a specific slot, transmission of the uplink data channel may not be performed in the specific slot.

[0312] That is, as illustrated in FIG. 18, there may be cases where both non-SBFD symbols and SBFD symbols exist within a specific slot, and symbol resources allocated / configured for PUSCH (including TBoMS) repeated transmission include both SBFD symbols and non-SBFD symbols.

[0313] At this time, if PUSCH repetition type A is set, PUSCH transmission in the specific slot can be dropped / skipped. According to this method, when performing PUSCH repetition type A, only symbols of the same type exist in each slot where PUSCH repetition is actually performed. Therefore, the complexity in performing PUSCH repetition type A can be reduced, and a situation in which transmission power / transmit / receive beams, etc. must be changed due to a change in the symbol type of each symbol within each slot can be prevented.

[0314] Meanwhile, in the case of repeatedly transmitting an uplink data channel (PUSCH) in the second repetition type (PUSCH repetition type B), if both the FD time resource and the HD time resource are included for transmission of the uplink data channel within a specific slot, the uplink data channel may be repeatedly transmitted through different actual transmission resources based on the boundary between the FD time resource and the HD time resource.

[0315] This method allows each PUSCH to be transmitted using only symbols of the same symbol type, thereby preventing variations in frequency resources, transmission power, and transmission beams for PUSCH transmission depending on the transmission symbol. Consequently, the complexity of PUSCH transmission can be reduced and PUSCH transmission efficiency can be increased.

[0316] In some embodiments, when the time resources constituting the PUSCH transmission include both SBFD symbols and non-SBFD symbols, the PUSCH transmission may or may not be performed depending on the frequency resources allocated for the PUSCH transmission. That is, when the time resources constituting the PUSCH transmission include both SBFD symbols and non-SBFD symbols, whether or not to transmit the PUSCH may depend on the frequency resources allocated for the PUSCH transmission.

[0317] For example, if the time resources configuring PUSCH transmission include both SBFD symbols and non-SBFD symbols, in order for the terminal to transmit the PUSCH, the frequency resources (e.g., PRB) allocated for PUSCH transmission must not include resources other than UL subbands.

[0318] That is, when the time resources constituting the PUSCH transmission include both SBFD symbols and non-SBFD symbols, i) if the PRB resources allocated for the PUSCH transmission include resources other than the UL subband, the UE does not transmit the PUSCH, and ii) if all the PRB resources allocated for the PUSCH transmission are included within the UL subband, the UE can transmit the PUSCH.

[0319] FIG. 21 illustrates a PUSCH repetition transmission method when a PUSCH is repeatedly transmitted with PUSCH repetition type B and different types of symbols (SBFD symbols and non-SBFD symbols) are included within a specific slot.

[0320] As illustrated in FIG. 21, slot #N includes both SBFD symbols and non-SBFD symbols, and slot #N+1 includes only SBFD symbols. However, there may be a case where symbol resources allocated / configured for PUSCH transmission include both SBFD symbols and non-SBFD symbols.

[0321] In Fig. 21, among the four symbols constituting Nominal Rep2, the first and second symbols are SBFD symbols, and the third and fourth symbols are non-SBFD symbols. In this case, the first and second symbols constitute one actual repetition based on the boundary between the SBFD symbol resource and the non-SBFD symbol resource, and the third and fourth symbols constitute another actual repetition. That is, in the four symbols constituting Nominal Rep2, the uplink data channel is repeatedly transmitted through different actual transmission resources based on the boundary between the FD time resource (SBFD symbol) and the HD time resource (non-SBFD symbol).

[0322] Then, two actual repetition transmissions are performed based on the slot boundary.

[0323] Therefore, when PUSCH repetition type B is set, the four nominal repetitions (nominal repetition 0 to nominal repetition 3) of FIG. 21 can be performed with a total of five actual repetitions (actual repetitions) in slot #N and one actual repetition in slot #N+1.

[0324] This method ensures that all symbols in each actual repetition have the same symbol type. That is, all symbols in each actual repetition are either SBFD symbols or non-SBFD symbols. Therefore, there is no need for different transmit power or different transmit / receive beams for each symbol in a single actual repetition transmission, which has the advantage of eliminating this.

[0325] Figure 22 illustrates a signaling process and operation method between a base station and a terminal.

[0326] Referring to Figure 22, the base station provides TDD setting information to the terminal (S221).

[0327] TDD configuration information is an example of information for setting the HD time resources and HD frequency resources described above.

[0328] The base station provides FD resource information to the terminal (S222). The FD resource information may be information that informs the terminal of FD time resources and / or FD frequency resources.

[0329] The base station provides a repetition type indicator to the terminal (S223).

[0330] For example, the base station may provide an indicator (e.g., 'pusch-RepTypeIndicatorDCI-0-1', 'pusch-RepTypeIndicatorDCI-0-2') indicating the type of PUSCH repetitive transmission via an RRC message / information element ('PUSCH-Config') used to configure terminal-specific PUSCH parameters applicable to a specific bandwidth part (BWP).

[0331] The terminal determines the repetition type (S224). For example, the terminal may determine the type of PUSCH repetition transmission as PUSCH repetition type A or PUSCH repetition type B based on the repetition type indicator.

[0332] When both FD time resources and HD time resources are included in a slot for transmission of an uplink data channel, the terminal performs transmission operations of the uplink data channel differently according to the determined repetition type (and / or depending on whether the frequency resources set for transmission of the uplink data channel are all included in the UL subband) (S225). The frequency resources set for transmission of the uplink data channel can be dynamically set by DCI.

[0333] The specific operation is described in detail with reference to Figures 18 to 21.

[0334] Figure 23 illustrates a wireless device applicable to the present specification.

[0335] Referring to FIG. 23, the first wireless device (100) and the second wireless device (200) can transmit and receive wireless signals through various wireless access technologies (e.g., LTE, NR).

The processor (102).

[0337] Information used to set parameters of an uplink data channel applicable to a specific frequency band is received, and repeated transmission of the uplink data channel is performed based on the information. In the repeated transmission, if time resources set for transmission of a specific uplink data channel include both a full duplex (FD) time resource and a half duplex (HD) time resource, transmission of the specific uplink data channel is skipped / dropped, or transmission of the specific uplink data channel is skipped / dropped depending on the frequency resources set for transmission of the specific uplink data channel. The specific operation has been described with reference to FIGS. 18 to 21.

[0338] The second wireless device (200) includes one or more processors (202), one or more memories (204), and may further include one or more transceivers (206) and / or one or more antennas (208). The processor (202) controls the memories (204) and / or the transceivers (206), and may be configured to implement the descriptions, functions, procedures, proposals, methods, and / or operational flowcharts disclosed in this document. For example, the processor (202) may process information in the memory (204) to generate third information / signals, and then transmit a wireless signal including the third information / signals via the transceivers (206). Furthermore, the processor (202) may receive a wireless signal including fourth information / signals via the transceivers (206), and then store information obtained from signal processing of the fourth information / signals in the memory (204). The memory (204) may be connected to the processor (202) and may store various information related to the operation of the processor (202). For example, the memory (204) may perform some or all of the processes controlled by the processor (202), or may store software code including commands for performing the descriptions, functions, procedures, proposals, methods, and / or operation flowcharts disclosed in this document. Here, the processor (202) and the memory (204) may be part of a communication modem / circuit / chip designed to implement wireless communication technology (e.g., LTE, NR).

In this specification, a wireless device may also mean a communication modem / circuit / chip. The processor (202) transmits information used to set parameters of an uplink data channel applicable to a specific frequency band to the terminal, and repeatedly receives the uplink data channel based on the information.In the above repeated reception, if the time resources for reception of a specific uplink data channel include both a full duplex (FD) time resource and a half duplex (HD) time resource, reception of the specific uplink data channel is skipped / dropped, or reception of the specific uplink data channel is skipped / dropped depending on the frequency resources set for reception of the specific uplink data channel. The specific operation has been described with reference to FIGS. 18 to 21.

[0345] Fig. 24 illustrates an example of a signal processing module structure. Here, signal processing may be performed in the processor (102, 202) of Fig. 23.

[0346] Referring to FIG. 24, a transmission device (e.g., a processor, a processor and a memory, or a processor and a transceiver) within a terminal or a base station 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).

[0347] A transmitting device can transmit one or more codewords. The coded bits within each codeword are scrambled by a scrambler (301) and transmitted over a physical channel. A codeword may also be referred to as a data string and may be equivalent to a transport block, which is a data block provided by the MAC layer.

[0348] The scrambled bits are modulated into complex-valued modulation symbols by a modulator (302). The modulator (302) can modulate the scrambled bits according to a modulation scheme and arrange them into complex-valued modulation symbols that represent positions on a signal constellation. There is no limitation on the modulation scheme, and m-PSK (m-Phase Shift Keying) or m-QAM (m-Quadrature Amplitude Modulation) can be used to modulate the encoded data. The modulator may be referred to as a modulation mapper.

[0349] The complex modulation symbols may be mapped to one or more transmission layers by a layer mapper (303). The complex modulation symbols on each layer may be mapped by an antenna port mapper (304) for transmission on an antenna port.

[0350] The resource block mapper (305) can map the complex modulation symbol for each antenna port to an appropriate resource element within a virtual resource block (VRB) allocated for transmission. The resource block mapper can map the VRB to a physical resource block (PRB) according to an appropriate mapping scheme. The resource block mapper (305) can assign the complex modulation symbol for each antenna port to an appropriate subcarrier and multiplex it according to the user.

[0351] The signal generator (306) can generate a complex-valued time domain OFDM symbol signal by modulating a complex modulation symbol for each antenna port, i.e., an antenna-specific symbol, with a specific modulation method, for example, an Orthogonal Frequency Division Multiplexing (OFDM) method. The signal generator can perform an Inverse Fast Fourier Transform (IFFT) on the antenna-specific symbol, and a Cyclic Prefix (CP) can be inserted into the time domain symbol on which the IFFT is performed. The OFDM symbol is transmitted to a receiving device through each transmitting antenna through digital-to-analog conversion, frequency uplink conversion, etc. The signal generator can include an IFFT module, a CP inserter, a Digital-to-Analog Converter (DAC), a frequency uplink converter, etc.

[0352] Fig. 25 illustrates another example of a signal processing module structure within a transmission device. Here, signal processing may be performed in a processor of a terminal / base station, such as the processor (102, 202) of Fig. 23.

[0353] Referring to FIG. 25, a transmission device (e.g., a processor, a processor and a memory, or a processor and a transceiver) in a terminal or a base station 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).

[0354] The transmitting device can transmit coded bits within a codeword through a physical channel after scrambling the coded bits within the codeword by a scrambler (401).

[0355] The scrambled bits are modulated into complex modulation symbols by a modulator (402). The modulator can modulate the scrambled bits according to a predetermined modulation scheme and arrange them into complex modulation symbols representing positions on a signal constellation. There is no limitation on the modulation scheme, and pi / 2-BPSK (pi / 2-Binary Phase Shift Keying), m-PSK (m-Phase Shift Keying), or m-QAM (m-Quadrature Amplitude Modulation) can be used to modulate the encoded data.

[0356] The above complex modulation symbol can be mapped to one or more transmission layers by the layer mapper (403).

[0357] The complex modulation symbols on each layer can be precoded by the precoder (404) for transmission on the antenna ports. Here, the precoder may perform precoding after performing transform precoding on the complex modulation symbols. Alternatively, the precoder may perform precoding without performing transform precoding. The precoder (404) may process the complex modulation symbols in a MIMO manner according to multiple transmission antennas to output antenna-specific symbols and distribute the antenna-specific symbols to the corresponding resource block mapper (405). The output z of the precoder (404) can be obtained by multiplying the output y of the layer mapper (403) by the precoding matrix W of NХM. Here, N is the number of antenna ports and M is the number of layers.

[0358] The resource block mapper (405) maps the demodulation modulation symbol for each antenna port to the appropriate resource element within the virtual resource block allocated for transmission.

[0359] The resource block mapper (405) can assign complex modulation symbols to appropriate subcarriers and multiplex them according to the user.

[0360] The signal generator (406) can generate a complex-valued time domain OFDM (Orthogonal Frequency Division Multiplexing) symbol signal by modulating a complex modulation symbol with a specific modulation method, for example, OFDM. The signal generator (406) can perform an Inverse Fast Fourier Transform (IFFT) on an antenna-specific symbol, and a Cyclic Prefix (CP) can be inserted into the time domain symbol on which the IFFT has been performed. The OFDM symbol is transmitted to a receiving device through each transmitting antenna after going through digital-to-analog conversion, frequency upconversion, etc. The signal generator (406) can include an IFFT module, a CP inserter, a Digital-to-Analog Converter (DAC), a frequency uplink converter, etc.

[0361] The signal processing process of the receiving device may be configured in reverse order of the signal processing process of the transmitter. Specifically, the processor of the receiving device performs decoding and demodulation on a wireless signal received externally through the antenna port(s) of the transceiver. The receiving device may include a plurality of multiple receiving antennas, and each signal received through the receiving antenna is restored to a baseband signal and then multiplexed and MIMO demodulated to be restored to a data sequence originally intended to be transmitted by the transmitting device. The receiving device (1820) may include a signal restorer for restoring the received signal to a baseband signal, a multiplexer for combining and multiplexing the received and processed signals, and a channel demodulator for demodulating the multiplexed signal sequence into a corresponding codeword. The signal restorer, the multiplexer, and the channel demodulator may be configured as an integrated module performing their functions or as individual modules. More specifically, the signal restorer may include an analog-to-digital converter (ADC) that converts an analog signal into a digital signal, a CP remover that removes a CP from the digital signal, an FFT module that applies an FFT (fast Fourier transform) to a signal from which the CP has been removed to output a frequency domain symbol, and a resource element demapper / equalizer that restores the frequency domain symbol to an antenna-specific symbol. The antenna-specific symbol is restored to a transmission layer by a multiplexer, and the transmission layer is restored to a codeword that the transmitter intended to transmit by a channel demodulator.

Artificial Intelligence (AI) technology can be applied to the wireless devices (100a to 100f), and the wireless devices (100a to 100f) can be connected to an AI server (400) via the network (300). The network (300) can be configured using a 3G network, a 4G (e.g., LTE) network, a 5G (e.g., NR) network, etc. The wireless devices (100a to 100f) can communicate with each other via the base station (200) / network (300), but can also communicate directly (e.g., sidelink communication) without going through the base station / network.

[0390] The NR frequency band can be defined by two types of frequency ranges (FR1, FR2). The numerical values ​​of the frequency ranges can be changed, and for example, the frequency ranges of the two types (FR1, FR2) can be as shown in Table 5 below. For convenience of explanation, among the frequency ranges used in the NR system, FR1 can mean the “sub 6 GHz range”, and FR2 can mean the “above 6 GHz range” and can be called millimeter wave (mmW).

[0391] [Table 5]

[0392]

[0393] As described above, the numerical value of the frequency range of the NR system can be changed. For example, FR1 may include a band from 410 MHz to 7125 MHz, as shown in Table 6 below. That is, FR1 may include a frequency band above 6 GHz (or 5850, 5900, 5925 MHz, etc.). For example, the frequency band above 6 GHz (or 5850, 5900, 5925 MHz, etc.) included within FR1 may include an unlicensed band. The unlicensed band may be used for various purposes, such as for vehicular communications (e.g., autonomous driving).
