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] Wireless communication systems, whether NR or later, can perform full duplex (FD) operation. In FD operation, a device can simultaneously perform downlink reception and uplink transmission within a specific time resource. This differs from half duplex (HD) operation, which can perform either downlink reception or uplink transmission within a specific time resource.

[0004] For FD operation, i) some frequency resources in the same time resource may be allocated as downlink subbands and other frequency resources as uplink subbands (this may be referred to as subband FD, or subband-wise full duplex (SBFD), or 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).

[0005] Meanwhile, in the case of time / frequency resources in which a device operates as FD (which may be referred to as FD resources), the channel environment may be worse than that in the case of time / frequency resources in which a device operates as HD (which may be referred to as HD resources) due to cross-link interference (CLI), self-interference (SI), etc.

[0006] Therefore, when transmitting uplink control information (UCI) in a time resource operating as an FD, if a code rate, number of coded modulation symbols, etc. determined based on HD resources are used, transmission of the UCI may not be performed successfully.

[0007] Considering these points, when transmitting UCI in a communication system supporting FD operation, a method and device for determining the code rate or the number of coded modulation symbols considering FD resources are required.

[0008] 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.

[0009] 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 generates uplink control information (UCI) and transmits the UCI to the network through a physical uplink shared channel (PUSCH) of a slot. At this time, with respect to a specific parameter used to determine the number of coded modulation symbols per layer for transmission of the UCI, a first parameter value is applied when the slot is an FD slot configured with FD (full duplex) resources, and a second parameter value is applied when the slot is an HD slot configured with HD (half duplex) resources.

[0010] In another aspect, a terminal, device, or computer-readable recording medium for executing the above method is provided.

[0011] 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 requests uplink control information (UCI) from a terminal, and the base station receives the UCI from the terminal through a physical uplink shared channel (PUSCH) of a slot. With respect to a specific parameter used to determine the number of coded modulation symbols per layer for reception of the UCI, a first parameter value is applied when the slot is an FD slot configured with FD (full duplex) resources, and a second parameter value is applied when the slot is an HD slot configured with HD (half duplex) resources.

[0012] According to the method according to the present disclosure, when UCI is multiplexed and transmitted on a PUSCH in an FD resource that may have a channel condition worse than the channel condition targeted by the base station, a code rate suitable for the FD resource can be applied, so that UCI can be transmitted reliably.

[0013] In addition, when UCI is transmitted through different types of resources, ambiguity can be prevented by clarifying the value of the parameter used to determine the number of coded modulation symbols of the UCI.

[0044] Technical features individually described in a single drawing in this specification may be implemented individually or simultaneously.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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).

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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).

[0062] 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.

[0063] Below, we describe new radio access technology (new RAT, NR).

[0064] 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.

[0065] Figure 4 illustrates the system architecture of a New Generation Radio Access Network (NG-RAN) to which NR is applied.

[0066] 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.

[0067] Figure 5 illustrates the functional division between NG-RAN and 5GC.

[0068] 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.

[0069] Figure 6 illustrates a frame structure that can be applied in NR.

[0070] 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).

[0071] Table 1 below illustrates the subcarrier spacing configuration μ (also referred to as subcarrier spacing configuration).

[0072] [Table 1]

[0073]

[0074] Table 2 below shows the number of slots (N) in a frame according to the subcarrier spacing setting μ. frame,μ slot ), number of slots in a subframe (N subframe,μ slot ), number of symbols in the slot (N slot symb ) are examples.

[0075] [Table 2]

[0076]

[0077] In Fig. 6, examples are given for μ=0, 1, 2, and 3.

[0078] 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.

[0079] [Table 2-1]

[0080]

[0081] 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.

[0082] Figure 7 illustrates a slot structure.

[0083] 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 BWPs (e.g., 4 or 5). 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.

[0084] A PDCCH (physical downlink control channel) may be composed of one or more CCEs (control channel elements) as shown in Table 3 below.

[0085] [Table 3]

[0086]

[0087] 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.

[0088] 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.

[0089] In NR, a new unit called a control resource set (CORESET) can be introduced. A terminal can receive PDCCHs in a CORESET.

[0090] Figure 8 illustrates a core set.

[0091] 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).

[0092] 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.

[0093] A terminal can be configured with multiple core sets.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] Meanwhile, in NR, depending on the application field, high reliability may be required, and in such a situation, the target BLER (block error rate) 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.

[0098] The following technologies / features can be applied in NR:

[0099] Self-contained subframe structure

[0100] Figure 9 illustrates an example of a frame structure for a new wireless access technology.

[0101] 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.

[0102] Figure 9 shows an example in which a downlink control region is located at the front of the TTI and an uplink control region is located at the back of the TTI. The region between the downlink control region and the uplink control region can be used for downlink data (DL data) transmission or uplink data (UL data) transmission. A characteristic of this structure is that downlink (DL) reception and uplink (UL) transmission are sequentially performed within a single subframe / slot, so that DL data can be received and UL ACK / NACK (Acknowledgement / Not-acknowledgement) can be transmitted within a single subframe / slot. 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.

[0103] In this way, in a data and control TDMed subframe structure, 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 point of transition from DL to UL in a self-contained subframe structure can be set as a guard period (GP).

[0104] Figure 10 illustrates the structure of a self-contained slot.

[0105] 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.

[0106] 1. DL only configuration

[0107] 2. UL only configuration

[0108] 3. Mixed UL-DL configuration

[0109] - DL area + GP (Guard Period) + UL control area

[0110] - DL control area + GP + UL area

[0111] DL area: (i) DL data area, (ii) DL control area + DL data area

[0112] UL domain: (i) UL data domain, (ii) UL data domain + UL control domain

[0113] 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.

[0114] Analog Beamforming #1

[0115] 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.

[0116] 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.

[0117] 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.

[0118] Analog Beamforming #2

[0119] 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.

[0120] 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.

[0121] 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.

[0122] 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.

[0123] 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.

[0124] 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.

[0125] 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.

[0126] 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:

[0127] 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),

[0128] 2) PDCCH DM-RS scrambling sequence initialization value,

[0129] 3) Interval in the time domain of the core set (can be given in symbol units),

[0130] 4) A set of resource blocks,

[0131] 5) CCE-to-REG mapping parameters,

[0132] 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');

[0133] 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.

[0134] 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.

[0135] 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.

[0136] 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).

[0137] [Table 4]

[0138]

[0139] 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.

[0140] 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:

[0141] 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 (common search space) or USS (UE-specific search space), etc.

[0142] 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.

[0143] Figure 11 illustrates physical channels and general signal transmission.

[0144] 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.

[0145] 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.

[0146] (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.

[0147] 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).

[0148] Thereafter, the terminal may perform a random access procedure (Random Access Procedure) to complete connection to the base station (S13-S16). Specifically, the terminal may 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 may 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 may be considered a process of receiving a contention resolution message) (S16).

[0149] 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.

[0150] 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.

[0151] 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.

[0152] 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.

[0153] 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.

[0154] 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).

[0155] In this disclosure, the following are defined:

[0156] - AC(x): Access link between node(x) and terminal(s).

[0157] - BH(xy): Backhaul link between node(x) and node(y).

[0158] 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.

[0159] 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.

[0160] <PUSCH 반복(repetitions)>

[0161] 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.

[0162] 1) PUSCH repetition type A

[0163] Figure 12 is an example of PUSCH repetition type A.

[0164] 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.

[0165] 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.

[0166] i) Frequency hopping within a slot is applicable to single slot and multi-slot PUSCH transmission.

[0167] ii) Inter-slot frequency hopping is applicable to multi-slot PUSCH transmission.

[0168] 2) PUSCH repetition type B

[0169] Figure 13 is an example of PUSCH repetition type B.

[0170] 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.

[0171] 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.

[0172] 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.

[0173] Invalid symbols may include the following:

[0174] i) Downlink symbol set by semi-static TDD UL-DL setting,

[0175] ii) an invalid symbol pattern set by RRC (which may be set by the invalid symbol pattern indicator);

[0176] iii) SSB symbol set by SIB1, SSB symbol set by 'ServngCellConfigCommon',

[0177] iv) Symbol for PDCCH for SIB1,

[0178] v) Invalid symbol for DL-UL switching set by RRC.

[0179] 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.

[0180] Now, we describe full duplex operation.

[0181] 5G is giving rise to new service types, such as extended reality (XR), AI-based services, and self-driving cars. These services feature dynamic traffic in both downlink (DL) and uplink (UL) directions, and require low latency for traffic transmission (e.g., packets). 5G services will experience explosive growth in traffic to support these diverse new use cases.

[0182] 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.

[0183] Figure 14 shows examples of how to apply full duplex within a carrier.

[0184] 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.

[0185] 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.

[0186] 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.

[0187] 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.

[0188] 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.

[0189] 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.

[0190] 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).

[0191] 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 from other adjacent carriers (which may be referred to as adjacent carrier interference (ACI)), 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 exclusively for DL ​​transmission.

[0192] 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.

[0193] 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.

[0194] 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.

[0195] 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.

[0196] In the present disclosure, the base station may perform / support full duplex operation, while the terminal may perform / support half duplex operation. Alternatively, in the present disclosure, both the base station and the terminal may perform / support full duplex operation.

[0197] <A. SBFD 및 SSFD 동작을 위한 DL / UL 시간 / 주파수 자원의 특성>

[0198] 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).

[0199] Through this operation, the network can change the time resource for performing transmission and reception between the first time resource and the second time resource depending on the type of signal / channel being transmitted and received or the terminal performing the transmission and reception. For example, in the case of important signals / channels (e.g., SSB, PRACH) that require high transmission and reception performance with less influence from interference, the resources can be set to transmit and receive only on the first time resource that operates only in half duplex. This allows the transmission and reception performance of the corresponding signals / channels to be maintained while applying full duplex to the cell. Alternatively, in the case of a terminal that cannot properly transmit and receive due to the significant influence of cross link interference (CLI) when operating in full duplex on the second time resource, the transmission and reception performance for the terminal can be guaranteed by setting the resources to perform transmission and reception on the first time resource.

[0200] The terminal / base station performs DL or UL operations across the entire frequency resources that constitute the entire system bandwidth in the first time resource where the HD operation is performed. Within the first time resource where the HD operation is performed, the network performs DL operations through the 1-1 time resource and UL operations 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.

[0201] The terminal / base station performs FD operation in the second time resource, and the network performs 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 UL operation through all or part of the frequency resources (second frequency resources).

[0202] Figure 16 shows examples of a first time resource, a second time resource, a first frequency resource, and a second frequency resource.

[0203] 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.

[0204] 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.

[0205] Figure 17 illustrates another example of a first time resource, a second time resource, a first frequency resource, and a second frequency resource.

[0206] 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.

[0207] 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.

[0208] The first frequency resource and / or the second frequency resource may have all or some of the following characteristics:

[0209] 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.

[0210] 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.

[0211] 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.

[0212] 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.

[0213] Through the above operation, the base station can perform a half-duplex operation in which only one of DL transmission or UL reception is performed in the entire frequency resources constituting the cell in the first time resource, and a full-duplex operation in which DL transmission is performed through the first frequency resource within the frequency resources constituting the cell and UL reception is simultaneously performed through the second frequency resource within the frequency resources constituting the cell in the second time resource.

[0214] The network can determine / judge the 'first time resource' and the 'second time resource', and the 'first frequency resource' and the 'second frequency resource' as described above, and provide all or part of the corresponding information to the terminal. The network can perform DL transmission to the terminal in the '1-1 time resource within the first time' and the '1 frequency resource within the second time resource', and perform UL reception from the terminal in the '1-2 time resource within the first time resource' and the '2 frequency resource within the second time resource'.

[0215] The terminal can receive all or part of the information about the 'first time resource' and the 'second time resource' and the 'first frequency resource' and the 'second frequency resource' from the network, and determine the location of the resources. The terminal can perform DL reception from the network through all or part of the '1-1 time resource within the first time' and the '1 frequency resource within the second time resource', and perform UL transmission to the network through the '1-2 time resource within the first time resource' and the '2 frequency resource within the second time resource'.

[0216] Meanwhile, in the existing NR TDD carrier, the base station performs only one operation, either downlink or uplink, in a specific time resource. In this case, the base station always operates in the downlink in the time resource where SSB is transmitted.

[0217] For terminals operating in existing TDD, the following is assumed for symbols in which SSB (SS / PBCH) is transmitted.

[0218] 1) SS / PBCH transmission symbols cannot be configured for uplink by TDD configuration (e.g., 'TDD-UL-DL-ConfigCommon' and / or 'TDD-UL-DL-ConfigDedicated').

[0219] 2) SS / PBCH transmission symbols cannot be set to uplink in SFI (slot format indication) by DCI format 2_0.

[0220] 3) When SS / PBCH is transmitted in a symbol set to flexible by TDD configuration (e.g., 'TDD-UL-DL-ConfigCommon' and / or 'TDD-UL-DL-ConfigDedicated'), if the uplink transmission of the terminal overlaps with the SS / PBCH symbol, the uplink transmission is not performed. In case of SRS, if it overlaps with the SS / PBCH symbol in the flexible symbol, SRS transmission is not performed in the overlapped symbol(s).

[0221] Meanwhile, in FDs such as SBFD and SSFD, both DL and UL resources can exist in the same time resource from the cell's perspective. Therefore, the base station can simultaneously perform downlink transmission and uplink reception. Therefore, even if SS / PBCH are transmitted in the time resource where the cell is performing FD operation, the base station can perform uplink reception while transmitting SS / PBCH.

[0222] Meanwhile, under the current standard, a terminal cannot perform uplink transmission on symbol resources where SS / PBCH is transmitted. In other words, a terminal cannot perform FD operations on the SS / PBCH transmission time resources of a base station.

[0223] 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.

[0224] 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.

[0225] 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.

[0226] In this disclosure, we assume and describe SBFD operation, where a cell performs DL and UL simultaneously using different frequency resources (e.g., subbands) within the same time resource. However, the contents of this disclosure can also be applied to a cell performing SSFD operation.

[0227] In a wireless communication system, i) the base station may perform full duplex operation and the terminal may perform half duplex operation, ii) the base station may perform half duplex operation and the terminal may perform full duplex operation, or iii) both the base station and the terminal may support full duplex operation.

[0228] A terminal that knows that the base station can perform full duplex operation may be referred to as an FD-aware terminal hereinafter. A terminal that knows that the base station can perform SBFD operation may be referred to as an SBFD-aware terminal hereinafter. A terminal that knows that the base station can perform SSFD operation may be referred to as an SSFD-aware terminal hereinafter.

[0229] If a base station supports both half-duplex and full-duplex operation, it can inform the terminal of the resources (time or frequency, or both) on which it can (or expects to) perform half-duplex and full-duplex.

[0230] If the base station is a full-duplex base station capable of SSFD operation, UL reception may be possible simultaneously on some or all of the frequency resources available for DL ​​transmission at the base station. In other words, some frequency resources may support both DL transmission / reception and UL reception / transmission. In this case, information about frequency resources capable of SSFD can be communicated to the terminal. Furthermore, information about time resources capable of SSFD can be communicated to the terminal.

[0231] In the case of a full-duplex terminal, UL transmission may be possible simultaneously on some or all of the frequency resources available for DL ​​reception of the terminal. In the present disclosure, a terminal that performs half-duplex operation may be referred to as an HD terminal, and a terminal that can (or does) perform full-duplex operation may be referred to as an FD terminal.

[0232] When a base station performs full duplex operation such as SBFD or SSFD, it may perform SSFD and / or SBFD operation only for some time / frequency resources. When an SBFD-aware terminal and / or an SSFD-aware terminal knows the time / frequency resources on which a cell performs SSFD and / or SBFD operation, the terminal may perform the operation differently depending on whether the cell operates in half duplex (HD) or SBFD or SSFD. For example, the terminal may perform transmission and reception by differently determining the time / frequency resources on which it performs reception of a DL signal / channel and / or transmission of a UL signal / channel as HD resources, SBFD resources, or SSFD resources.

[0233] The base station may perform a half-duplex operation in which only one of DL transmission or UL reception is performed in the entire frequency resources constituting the cell in the time resources operating in HD, and may perform a full-duplex operation in which DL transmission is performed through the first frequency resource (i.e., DL subband resource) within the frequency resources constituting the cell and UL reception is simultaneously performed through the second frequency resource (i.e., UL subband resource) within the frequency resources constituting the cell in the time resources operating in SBFD and SSFD.

[0234] To this end, the base station determines / determines time resources corresponding to the first time resource (i.e., HD symbol) and the second time resource (i.e., FD symbol) and transmits configuration information regarding the first time resource (i.e., HD symbol) and / or the second time resource (i.e., FD symbol) to the terminal. The FD symbol may include both the SBFD symbol and the SSFD symbol. More specifically, the base station may determine / determine time resources corresponding to the HD symbol, the SBFD symbol, and / or the SSFD symbol, and transmit configuration information regarding the HD symbol, the SBFD symbol, and / or the SSFD symbol to the terminal.

[0235] At this time, the DL subband resources and / or UL subband resources may be configured differently in the time resources operating in SBFD and in the time resources operating in SSFD. In the time resources operating in SBFD, the DL subband resources and UL subband resources are configured so as not to overlap each other. On the other hand, in the time resources operating in SSFD, the DL subband resources and UL subband resources may be configured so as to overlap each other. The DL subband / UL subband resources may be configured with a portion of the frequency resources of the system bandwidth or with the entire frequency resources.

[0236] The terminal receives configuration information about an HD symbol, an SBFD symbol, and / or an SSFD symbol from the network, and determines the positions of the HD symbol, the SBFD symbol, and / or the SSFD symbol. At this time, the terminal performs DL reception (UL transmission) through the entire frequency resources for which the terminal is configured to operate DL reception (UL transmission) in the HD symbol. And, in the SBFD symbol and / or the SSFD symbol, the terminal performs DL reception (UL transmission) through DL subband (UL subband) resources that are the same as or limited (smaller) to the frequency resources for which the terminal performs DL reception (UL transmission) in the HD symbol. In this case, even if the terminal configures frequency resources that do not correspond to DL subband resources (UL subband resources) in the SBFD symbol and / or SSFD symbol resources for DL ​​reception (UL transmission), the terminal does not perform DL reception (UL transmission) in the frequency resources that do not correspond to DL subband resources (UL subband resources).

[0237] In the following, the term "network" may be interpreted as a base station, gNB, or CU / DU. Furthermore, the term "terminal (UE)" may be interpreted as a mobile terminal (MT) of an IAB node.

[0238] Hereinafter, in a wireless communication system supporting full duplex (FD) operation, a method is described in which a terminal determines the number of coded modulation symbols for UCI transmission differently depending on the time resource operating in FD and the time resource operating in HD.

[0239] For time / frequency resources operating in full duplex (FD), the channel environment may be worse than that of resources operating in half duplex (HD) due to cross-link interference (CLI), self-interference (SI), etc.

[0240] Therefore, when UCI transmission via PUCCH or PUSCH is performed on FD resources based on the channel environment of resources operating in HD, UCI transmission may not be performed properly.

[0241] Considering this, when a terminal transmits UCI in an FD slot, a method for adjusting the amount of UCI transmission resources and the transmission code rate of UCI is described so as to increase the amount of resources through which UCI is transmitted or reduce the transmission code rate through which UCI is transmitted compared to when UCI is transmitted in an HD slot.

[0242] The types of UCI transmitted by the terminal include, for example, HARQ-ACK, CSI Part 1, CSI Part 2, and CG-UCI. One or more of these various types of UCIs may be multiplexed and transmitted via PUCCH or PUSCH. A new type of UCI called UTO (unused transmission occasion(s))-UCI may be introduced for XR (Extended Reality). In the present disclosure, CG-UCI may be interpreted as being replaced with UTO-UCI.

[0243] Considering that a terminal can perform FD operation and whether the terminal operates HD / FD may vary depending on time resources, in the present disclosure, 'resources for a cell to operate in HD' and 'resources for a cell to operate in FD' may be replaced with 'resources for a terminal to operate in HD' and 'resources for a terminal to operate in FD', respectively.

[0244] In the present disclosure, a method is proposed for a terminal to determine the number of coded modulation symbols for UCI transmission differently depending on the time resource when the cell operates in FD and the time resource when the cell operates in HD during intra-carrier full duplex operation.

[0333] As can be seen from the above equations 1 to 5, the number of coded modulation symbols per layer for each UCI (which can also be referred to as the number of UCI transmission REs according to the UCI type) is configured in the form of min{A, B}. The above min{A, B} is a function that outputs the minimum value among A and B.

[0334] In the above min{A,B}, the left term A can be seen as a part for determining the number of UCI transmission REs based on the code rate of the PUSCH, and the number of UCI transmission REs is obtained based on the 'UCI payload size' and 'the number of PUSCH transmission REs / the number of PUSCH transmission bits'. At this time, β PUSCHoffset The number of REs transmitted in UCI is scaled by the offset value.

[0335] Offset values ​​can be defined to determine the number of resources for multiplexing HARQ-ACK information by the UE and the number of resources for multiplexing CSI reports on the PUSCH. Offset values ​​are also defined to multiplex CG-UCI on the CG-PUSCH. Offset values ​​are signaled to the UE through the DCI format that schedules PUSCH transmission or by a higher layer.

[0337] In the above min{A,B}, the right term B can be seen as a part for setting the upper bound of the number of UCI transmission REs, and restricts the number of UCI transmission REs so that they do not exceed α(alpha) x 'the number of PUSCH transmission REs'. This α(alpha) value is set by the upper layer parameter 'scaling'.

[0338] In the present disclosure, when a terminal transmits UCI via PUSCH in a cell performing FD operation, a method for determining the number of coded modulation symbols for UCI transmission differently depending on the time resources when the cell operates as FD and the time resources when the cell operates as HD is described.

[0339] Hereinafter, for convenience of explanation, the number of coded modulation symbols per layer when UCI is transmitted on PUSCH is referred to as Q'. This Q' is determined by the type of UCI transmitted by the terminal. ACK , Q' CSI-1 , Q' CSI-2 , Q' CG-UCI It can mean back.

[0340] Proposal 1. β according to slot type PUSCH offset How to judge.

[0341] According to the conventional standard, β PUSCH offset The value of can be semi-statically set to the terminal by RRC signaling or dynamically indicated by DCI signaling. When transmitting UCI by multiplexing it in a general PUSCH transmission, for example, β can be set through 'betaOffsets' of the 'UCI-OnPUSCH' field as follows. PUSCH offset Relevant information can be set from the base station to the terminal.

[0342] [Table 5]

[0343]

[0344] β PUSCH offset (Let's call this a beta offset) If the value is set semi-statically, 'betaOffsets' in Table 5 is indicated as 'semiStatic' and one 'BetaOffsets' is indicated.

[0345] A single 'BetaOffsets' information element (IE) contains the indices of beta offsets for multiple UCI types (this can be called the beta offset index, e.g., if the UCI is HARQ-ACK, I HARQ-ACK offsetEach value is indicated. In the present disclosure, each index information indicated through the 'BetaOffsets' IE (e.g., betaOffsetACK-Index1, betaOffsetACK-Index2, betaOffsetACK-Index3, betaOffsetCSI-Part1-Index1, betaOffsetCSI-Part1-Index2, betaOffsetCSI-Part2-Index1, betaOffsetCSI-Part2-Index2, etc.) is referred to as an index of beta offset information or a beta offset index.

[0346] At this time, β is mapped to the beta offset index according to each UCI type. PUSCH offset The value of can be defined in the standard specification. That is, if the terminal is indicated as 'betaOffsets' as 'semiStatic', the β corresponding to the index indicated by 'BetaOffsets' PUSCH offset β, the value applied by the terminal PUSCH offset Judge by value.

[0347] For example, the terminal is I HARQ-ACK offset,0 The value of 'betaOffsetACK-Index1' of 'BetaOffsets' can be set. In this case, the terminal sets the value of the set 'betaOffsetACK-Index1' to I HARQ-ACK offset,0 Judging by the value of , I in the standard specification HARQ-ACK offset,0 β mapped to the value of HARQ-ACK offset β is the value applied by the terminal HARQ-ACK offset It can be judged by value.

[0348] β PUSCH offsetWhen the value of is dynamically indicated, 'betaOffsets' in Table 5 is indicated as 'dynamic', and multiple 'BetaOffsets' are indicated. Each 'BetaOffsets' IE indicates the index values ​​of the beta offsets for multiple UCI types as follows.

[0349] Afterwards, the terminal is instructed on the 'BetaOffsets' information to be applied by the terminal among multiple 'BetaOffsets' information through a specific field (e.g., the 'beta_offset indicator' field) in the UL grant. Depending on the 'beta_offset indicator' value, the 'BetaOffsets' information to be applied by the terminal can be defined in the standard specification.

[0350] That is, the terminal determines the index value of the beta offset to be applied according to the instructed 'beta_offset indicator'. Afterwards, the terminal maps β to the index of the beta offset to be applied. PUSCH offset β is the value applied by the terminal PUSCH offset It is judged by the value of .

[0351] For example, a terminal can set multiple 'betaOffsetACK-Index1' values ​​by setting multiple 'BetaOffsets'. After that, the terminal is instructed to the 'beta_offset indicator' value applied by the terminal through the 'beta_offset indicator' field in the UL grant. If the 'beta_offset indicator' value is instructed as i, the terminal sets the value of 'betaOffsetACK-Index1' set to the ith 'BetaOffsets' instructed by 'betaOffsets' as I. HARQ-ACK offset,0 It is judged by the value of the terminal. The terminal is the above I HARQ-ACK offset,0 β mapped to the value of HARQ-ACKoffset β is the value applied by the terminal HARQ-ACK offset It can be judged by value.

[0352] Table 6 is an example of 'BetaOffsets'.

[0353] [Table 6]

[0354]

[0355] As described above, in the present disclosure, in order for the terminal to determine Q', which is the number of coded modulation symbols per layer of UCI, β is applied according to the slot type of the slot transmitting UCI. PUSCH offset The value of is judged differently.

[0356] At this time, the slot type may mean an HD slot and an FD slot. That is, depending on whether the slot in which the terminal multiplexes UCI to the PUSCH and transmits it is an HD slot or an FD slot, the terminal applies β. PUSCH offset The value of can be judged differently.

[0357] The above HD slot and FD slot may more specifically mean the following.

[0358] An HD slot may mean a slot in which all symbols within the slot operate as HD. On the other hand, an FD slot may mean i) a slot in which all symbols within the slot operate as FD. ii) or a slot in which at least one symbol within the slot operates as FD.

[0359] Alternatively, an HD slot may mean a slot in which all symbol resources for transmitting a PUSCH by a terminal in the slot are composed of symbols operating as HD (e.g., UL symbols). On the other hand, an FD slot may mean either i) a slot in which all symbol resources for transmitting a PUSCH by a terminal in the slot are symbols operating as FD, or ii) a slot in which at least one symbol among symbol resources for transmitting a PUSCH in the slot is a symbol operating as FD.

[0360] In the present disclosure, a symbol / slot operating in HD may refer to a symbol / slot for which a base station has semi-statically configured the terminal to operate in HD. In the present disclosure, a symbol / slot operating in FD may refer to a symbol / slot for which a base station has semi-statically configured the terminal to operate in FD. Thereafter, when a terminal is dynamically instructed by the base station that a specific symbol / slot resource operates in HD or FD, the terminal may determine a slot for transmitting UCI by considering only the semi-statically instructed information.

[0361] The terminal applies β to HD slots and FD slots as follows: PUSCH offset The value of can be judged differently.

[0362] Option 1. The terminal applies β for HD slots and FD slots through RRC signaling from the base station. PUSCH offset The value of β is independently indicated. More specifically, at least one of the following options 1-1 and 1-2 is indicated. PUSCH offset Information about can be indicated. Option 1 is β PUSCH offset This can be applied both when the value is set statically and when it is indicated dynamically.

[0363] Option 1-1. The beta offset indices applied to HD slots and the beta offset indices applied to FD slots are independently set within the 'BetaOffsets' IE, which is a higher layer parameter. In this case, if the slot transmitting the UCI is an HD slot, the terminal applies the beta offset index applied to the HD slot to set β. PUSCH offset The value of can be determined. Or, if the slot transmitting the UCI is an FD slot, the beta offset index applied to the FD slot can be applied to β PUSCH offset The value of can be judged.

[0364] Option 1-2. For the upper layer parameter 'betaOffsets', the 'BetaOffsets' information applied to the HD slot and the 'BetaOffsets' information applied to the FD slot are set independently.

[0365] i) More specifically, when 'betaOffsets' = 'semiStatic', the 'BetaOffsets' information applied to the HD slot and the 'BetaOffsets' information applied to the FD slot can be set independently. In this case, if the slot transmitting the UCI is an HD slot, the terminal applies the 'BetaOffsets' information applied to the HD slot to set the beta offset index and the resulting β. PUSCH offset The value of can be determined. Or, if the slot transmitting the UCI is an FD slot, the 'BetaOffsets' information applied to the FD slot can be applied to determine the beta offset index and the resulting β. PUSCH offset The value of can be judged.

[0366] ii) If 'betaOffsets' = 'dynamic',

[0367] 1) Multiple 'BetaOffsets' (sequence of BetaOffsets) applied to the HD slot and multiple 'BetaOffsets' (sequence of BetaOffsets) applied to the FD slot can be independently set. In this case, when the slot transmitting the UCI is an HD slot, the terminal determines the 'BetaOffsets' information corresponding to the 'beta_offset indicator' indicated through the DCI among the multiple 'BetaOffsets' (sequence of BetaOffsets) applied to the HD slot, and applies the corresponding 'BetaOffsets' information to generate a beta offset index and the corresponding β. PUSCH offset The value of can be determined. Or, if the slot transmitting the UCI is an FD slot, the terminal determines the 'BetaOffsets' information corresponding to the 'beta_offset indicator' indicated through DCI among multiple 'BetaOffsets' (sequence of BetaOffsets) applied to the FD slot, and applies the 'BetaOffsets' information to determine the beta offset index and the corresponding β. PUSCH offset The value of can be judged.

[0368] 2) Or, in the case where multiple 'BetaOffsets' (sequence of BetaOffsets) composed of A 'BetaOffsets' are set in the prior art, in the method of option 1-2, multiple 'BetaOffsets' (sequence of BetaOffsets) composed of 2*A 'BetaOffsets' can be set. In this case, A 'BetaOffsets' can be 'BetaOffsets' applied to HD slots, and the remaining A 'BetaOffsets' can be 'BetaOffsets' applied to FD slots. In this case, when the slot transmitting the UCI is an HD slot, the terminal determines the 'BetaOffsets' information corresponding to the 'beta_offset indicator' indicated through DCI among the A 'BetaOffsets' applied to the HD slot, and applies the corresponding 'BetaOffsets' information to determine the beta offset index and the corresponding β. PUSCH offset The value of can be determined. Or, if the slot transmitting the UCI is an FD slot, the terminal determines the 'BetaOffsets' information corresponding to the 'beta_offset indicator' indicated through the DCI among the remaining A 'BetaOffsets' applied to the FD slot, and applies the 'BetaOffsets' information to determine the beta offset index and the corresponding β. PUSCH offset The value of can be judged.

[0369] That is, when a terminal is instructed to a specific beta offset index, if the slot transmitting UCI is an HD slot, the terminal can determine the 'BetaOffsets' corresponding to the beta offset index within the 'BetaOffsets' applied to the HD slot, and if the slot transmitting UCI is an FD slot, the terminal can determine the 'BetaOffsets' corresponding to the beta offset index within the 'BetaOffsets' applied to the FD slot.

[0370] Option 1-3. For the 'betaOffsets' information, which is an upper layer parameter, the 'betaOffsets' applied to the HD slot and the 'betaOffsets' applied to the FD slot are independently set. For example, the 'betaOffsets' applied to the HD slot and the 'betaOffsets' applied to the FD slot are independently set within 'UCI-OnPUSCH'. In this case, if the slot transmitting the UCI is an HD slot, the terminal applies the 'betaOffsets' information applied to the HD slot to set the beta offset index and the resulting β. PUSCH offset The value of can be determined. Or, if the slot transmitting the UCI is an FD slot, the terminal applies the 'betaOffsets' information applied to the FD slot to determine the beta offset index and the resulting β. PUSCH offset The value of can be judged.

[0371] Option 2. The terminal receives β applied to HD slots and FD slots from the base station through DCI (UL grant). PUSCH offset The value of β is independently indicated. More specifically, as in the following option 2-1, PUSCH offset Information about can be indicated. This method is β PUSCH offset This can be applied when the value is dynamically indicated.

[0372] Option 2-1. The 'beta_offset indicator' for HD slots and the 'beta_offset indicator' for FD slots can be independently indicated via DCI. In this case, if the slot transmitting UCI is an HD slot, the terminal applies the 'beta_offset indicator' applied to the HD slot to determine the beta offset index and the corresponding β. PUSCH offset The value of can be determined. If the slot transmitting the UCI is an FD slot, the terminal applies the 'beta_offset indicator' applied to the FD slot to determine the beta offset index and the corresponding β. PUSCH offset The value of can be judged.

[0373] Option 3. β means the information set / instructed by the terminal PUSCH offset Information may be interpreted differently depending on the slot type (HD slot or FD slot). More specifically, it may be as follows:

[0374] Option 3-1. The beta offset index information indicated by the 'beta_offset indicator' value indicated through DCI can be independently defined for the HD slot and the FD slot. That is, for a specific 'beta_offset indicator' value indicated to the terminal, the beta offset index information (i.e., the 'BetaOffsets' information applied among multiple 'BetaOffsets') mapped to the corresponding 'beta_offset indicator' value can be different depending on whether the slot to transmit the UCI is an HD slot or an FD slot. In this case, the terminal, for the 'beta_offset indicator' value indicated through DCI, if the slot to transmit the UCI is an HD slot, can define the beta offset index information mapped to the corresponding 'beta_offset indicator' value in the HD slot and the β accordingly. PUSCH offsetThe value of can be determined. Or, if the slot to transmit UCI is an FD slot, the terminal can determine the beta offset index information mapped to the 'beta_offset indicator' value in the FD slot and the β according to it for the 'beta_offset indicator' value instructed through DCI. PUSCH offset The value of can be judged.

[0375] Option 3-2. β mapped to the beta offset index information determined by the terminal. PUSCH offset The values ​​can be defined independently for the HD slot and the FD slot. That is, for a specific beta offset index information determined by the terminal, β mapped to the corresponding index information PUSCH offset The value may vary depending on whether the slot to transmit the UCI is an HD slot or an FD slot. In this case, the terminal, for a specific beta offset index value, maps the beta offset index value in the HD slot to the corresponding beta offset index value. PUSCH offset β is the value applied by the terminal PUSCH offset can be judged by the value of . Or, if the slot to transmit UCI is an FD slot, β mapped to the corresponding beta offset index value in the FD slot PUSCH offset β is the value applied by the terminal PUSCH offset can be judged by its value.

[0376] Option 3-3. The beta offset index information applied by the terminal may be interpreted / judged differently for HD slots and FD slots.

[0377] For example, I am using the beta offset index information determined by the terminal based on the existing standard specifications. HD When the terminal transmits UCI, if the slot is an HD slot, I HD β mapped to PUSCHoffset β is the value applied by the terminal PUSCH offset can be judged by the value of . On the other hand, if the slot transmitting the UCI is an FD slot, I HD +Z or I HD Determined by the beta offset index applying ХZ, and β mapped to that index PUSCH offset β is the value applied by the terminal PUSCH offset It can be judged by the value of . At this time, the Z value can be fixed / defined as a specific value by the standard specification. Alternatively, the Z value can be information set / instructed by the terminal from the base station through RRC / MAC-CE / DCI signaling, etc.

[0378] Option 3-4. β applied by the terminal according to the beta offset index determined by the terminal. PUSCH offset Values ​​may be interpreted / judged differently for HD slots and FD slots.

[0379] For example, β determined by the terminal based on the beta offset index information based on the existing standard specification PUSCH offset The value is β PUSCH offset,HD When the terminal transmits UCI, if the slot is an HD slot, β PUSCH offset,HD β, the value applied by the terminal PUSCH offset can be judged by the value of . If the slot transmitting the UCI is an FD slot, β PUSCH offset,HD +Y or β PUSCH offset,HD β applied to the terminal ХY PUSCH offset It can be judged by the value of Y. The above Y value can be fixed / defined as a specific value by the standard specification. Alternatively, the Y value can be information set / instructed by the terminal from the base station through RRC / MAC-CE / DCI signaling, etc.

[0380] β applied by the terminal to multiplex UCI onto PUSCH and transmit it PUSCH offset When judging the value, multiple methods among the above suggested methods may be applied together.

[0381] β applied by the terminal PUSCH offset Different proposal methods can be applied for cases where values ​​are determined semi-statically and dynamically.

[0382] According to the proposed method of the present disclosure, the terminal can operate as follows.

[0383] The terminal determines the time resource for the cell to operate in HD and the time resource for the cell to operate in FD based on the configuration information from the base station.

[0384] Afterwards, when the terminal transmits UCI multiplexed on PUSCH in a specific slot n, the terminal uses the proposed method described above to determine β to be applied for the UCI transmission depending on whether the slot n is an HD slot or an FD slot. PUSCH offset Determine the value of .

[0385] After that, the terminal judges β PUSCH offset Based on the value, the number of coded modulation symbols per layer for UCI transmission is determined, and the output bit sequence after rate matching for UCI transmission is obtained according to the number.

[0386] Rate matching is the rate matching output sequence length E r =floor(E UCI / C UCI ) can be set to . Here, C UCI is the number of code blocks for UCI, and E UCI = N L ·Q' CG-UCI ·Qm It is. N L is the number of transmission layers of the PUSCH, and Q m is the modulation order of the PUSCH.

[0387] Thereafter, the terminal multiplexes the output bit sequence onto the PUSCH in slot n and transmits it to the base station.

[0388] According to the proposal of the present disclosure, the base station can operate as follows.

[0389] The base station determines / determines the resources for the cell to operate as FD and / or HD and signals information about the time resources for the cell to operate as HD and / or FD to the terminal.

[0390] The base station requests UCI information such as HARQ-ACK, CSI, and SR from the terminal and receives this UCI information through PUCCH or PUSCH.

[0391] When the base station receives UCI information from the terminal via PUSCH, the base station uses the proposed method described above to determine β to be applied for the corresponding UCI transmission depending on whether the corresponding slot n is an HD slot or an FD slot. PUSCH offset Determine the value of .

[0392] After that, the base station judged β PUSCH offset The number of coded modulation symbols per layer for UCI transmission is determined based on the value, and UCI is received based on that number.

[0393] Proposal 2. Method for determining the α (alpha) value according to slot type

[0394] According to existing standards, the value of α (alpha) can be semi-statically set to the terminal via RRC signaling. When UCI is multiplexed and transmitted in a typical PUSCH transmission, for example, the value of α (alpha) applied by the terminal is set by the base station to the terminal through "scaling" in the "UCI-OnPUSCH" field, as follows.

[0395] [Table 7]

[0396]

[0397] In the present disclosure, it is proposed that, in order for a terminal to determine the number of coded modulation symbols per layer of UCI, Q', the value of α (alpha) applied is determined differently depending on the slot type of the slot transmitting UCI.

[0398] The above slot type may include an HD slot and an FD slot. That is, depending on whether the slot in which the terminal multiplexes UCI onto the PUSCH and transmits it is an HD slot or an FD slot, the terminal may determine the value of α (alpha) to be applied differently.

[0399] At this time, HD slot and FD slot may more specifically mean the following.

[0400] An HD slot may mean a slot in which all symbols within the slot operate as HD. On the other hand, an FD slot may mean either i) a slot in which all symbols within the slot operate as FD, or ii) a slot in which at least one symbol within the slot operates as FD.

[0401] Alternatively, an HD slot may refer to a slot in which all symbol resources for transmitting PUSCH in the slot are composed of symbols operating as HD. On the other hand, an FD slot may refer to a slot in which i) all symbol resources for transmitting PUSCH in the slot are symbols operating as FD, or ii) at least one symbol among symbol resources for transmitting PUSCH in the slot is a symbol operating as FD.

[0402] In the present disclosure, a symbol / slot operating in HD may refer to a symbol / slot for which a base station has semi-statically configured the terminal to operate in HD. In the present disclosure, a symbol / slot operating in FD may refer to a symbol / slot for which a base station has semi-statically configured the terminal to operate in FD. Thereafter, when a terminal is dynamically instructed by the base station that a specific symbol / slot resource operates in HD or FD, the terminal may determine a slot for transmitting UCI by considering only the semi-statically instructed information.

[0403] The terminal can determine the value of α (alpha) to be applied to the HD slot and the FD slot differently as follows.

[0404] Option 1. The terminal independently receives the values ​​of α (alpha) applied to the HD slot and FD slot from the base station via RRC signaling. To this end, the terminal can independently set the 'scaling' (let's call this scaling information) values ​​applied to the HD slot and FD slot from the base station via upper layer signaling. In this case, if the slot transmitting the UCI is an HD slot, the terminal can determine the value of α (alpha) by applying the scaling information applied to the HD slot. Alternatively, if the slot transmitting the UCI is an FD slot, the terminal can determine the value of α (alpha) by applying the scaling information applied to the FD slot.

[0405] Option 2. The terminal may interpret / judge the value of α (alpha) applied by the terminal differently for HD slots and FD slots, depending on the scaling value instructed by the base station through RRC signaling. For example, the value instructed through scaling may be α HD When the terminal transmits UCI, if the slot is an HD slot, α HD The value can be determined by the α (alpha) value applied by the terminal. If the slot transmitting the UCI is an FD slot, the terminal can determine α HD +W or α HD The ХW value can be determined as the α (alpha) value applied by the terminal. The W value can be fixed / defined as a specific value by the standard specification. Alternatively, the W value can be information set / indicated by the terminal from the base station through RRC / MAC-CE / DCI signaling, etc.

[0406] According to the proposal of the present disclosure, the terminal can operate as follows.

[0407] The terminal determines the time resource for the cell to operate in HD and the time resource for the cell to operate in FD based on the configuration information from the base station.

[0408] Thereafter, when the terminal multiplexes UCI onto PUSCH and transmits it in a specific slot n, the terminal uses the proposed method described above to determine the value of α (alpha) to be applied for the UCI transmission depending on whether the slot n is an HD slot or an FD slot.

[0409] Thereafter, the terminal determines the number of coded modulation symbols for each layer for UCI transmission based on the determined α (alpha) value, and obtains an output bit sequence after rate matching for UCI transmission according to the determined number.

[0410] Afterwards, the terminal multiplexes the corresponding output bit sequence into PUSCH transmission in slot n and transmits it to the base station.

[0411] According to the proposal of the present disclosure, the base station can operate as follows.

[0412] The base station determines / determines the resources for the cell to operate as FD and / or HD and signals information about the time resources for the cell to operate as HD and / or FD to the terminal.

[0413] The base station requests UCI information such as HARQ-ACK, CSI, and SR from the terminal and receives this UCI information through PUCCH or PUSCH.

[0414] When a base station receives UCI information from a terminal via PUSCH, the base station uses the proposed method described above to determine the value of α (alpha) to be applied for the corresponding UCI transmission depending on whether the corresponding slot n is an HD slot or an FD slot.

[0415] Afterwards, the base station determines the number of coded modulation symbols for each layer for UCI transmission based on the determined α (alpha) value, and receives UCI based on that number.

[0416] Proposal 3. M according to slot type PUSCH sc How to judge value

[0417] According to existing standards, M PUSCH sc The value means 'the scheduled bandwidth of the PUSCH transmission, expressed as a number of subcarriers' for PUSCH transmission that multiplexes UCI. If P physical resource blocks (PRBs) are allocated for PUSCH transmission, the number of subcarriers in one RB is N RB sc When said, M PUSCH sc The value is P·N RBsc It can be like this.

[0418] Meanwhile, for example, when a cell performs SBFD operation, some of the total time resources may be used for SBFD operation, and the remaining time resources may be used for conventional HD operation. In this case, there may be a case where the base station instructs the UE to transmit a PUSCH based on the time resources for performing HD operation, but the UE actually transmits the PUSCH using the time resources for performing SBFD operation.

[0419] In this case, in the HD operation time resource, the frequency resources that could be used for UL transmission may not be included in the UL subband in the SBFD operation time resource and thus may not be available for UL transmission. In this case, the terminal may perform actual PUSCH transmission using only some of the frequency resources included in the UL subband among the frequency resources allocated for PUSCH transmission from the base station.

[0420] In this case, even if the same frequency resource allocation is received for PUSCH transmission for HD operation time resources and SBFD operation time resources, the number of subcarriers used by the terminal for PUSCH transmission in SBFD time resources is M PUSCH sc It may be less than the value.

[0421] In the present disclosure, considering the case where the amount of frequency resources (e.g., the number of PRBs) that a terminal uses for the same PUSCH transmission is different in a slot where a cell operates in HD and a slot where a cell operates in FD, when the terminal determines Q', which is the number of coded modulation symbols per layer of UCI, M is applied according to the slot type of the slot transmitting UCI. PUSCH sc I suggest that the value of be judged differently.

[0422] At this time, the slot type may include an HD slot and an FD slot. That is, depending on whether the slot in which the terminal multiplexes UCI to the PUSCH and transmits it is an HD slot or an FD slot, the terminal applies the M PUSCH sc The value of can be judged differently.

[0423] At this time, HD slot and FD slot may more specifically mean the following.

[0424] An HD slot may mean a slot in which all symbols within the slot operate as HD. On the other hand, an FD slot may mean a slot in which all symbols within the slot operate as FD, or a slot in which at least one symbol within the slot operates as FD.

[0425] Alternatively, an HD slot may refer to a slot in which all symbol resources for transmitting a PUSCH by a terminal in the slot are symbols operating as HD (e.g., UL symbols). On the other hand, an FD slot may refer to a slot in which i) all symbol resources for transmitting a PUSCH by a terminal in the slot are symbols operating as FD, or ii) at least one symbol among symbol resources for transmitting a PUSCH in the slot is a symbol operating as FD.

[0426] In the present disclosure, a symbol / slot operating in HD may refer to a symbol / slot for which a base station has semi-statically configured the terminal to operate in HD. In the present disclosure, a symbol / slot operating in FD may refer to a symbol / slot for which a base station has semi-statically configured the terminal to operate in FD. Thereafter, when a terminal is dynamically instructed by the base station that a specific symbol / slot resource operates in HD or FD, the terminal may determine a slot for transmitting UCI by considering only the semi-statically instructed information.

[0427] The terminal applies M to the HD slot and FD slot as follows: PUSCH sc The value of can be judged differently.

[0428] The terminal receives frequency resource information for scheduling PUSCH from the base station through RRC and / or DCI signaling, and can determine that P1 PRBs are allocated for PUSCH transmission based on the information. In this case, if the slot transmitting UCI is an HD slot, the terminal determines M based on the number of P1 PRBs. PUSCH sc The value of can be determined. That is, if the slot transmitting the UCI is an HD slot, the terminal determines whether P1· N RB sc to M PUSCH sc It can be judged by value. If the slot transmitting UCI is an FD slot, the terminal determines M based on the number of PRBs used for PUSCH transmission in the corresponding slot among P1 PRBs. PUSCH sc The value of can be determined. That is, if the terminal transmits UCI in an FD slot, and the number of PRBs used for PUSCH transmission in the FD slot is P2, then P2· N RB sc to M PUSCH sc It can be judged by value.

[0429] At this time, more specifically, P2 can be as follows.

[0430] Alt a. P2 may be equal to the number of PRBs included in the UL subband among the PRBs allocated for PUSCH transmission.

[0431] Alternatively, P2 may be equal to the number of PRBs allocated for PUSCH transmission that are not included in the DL subband and / or guard subband.

[0432] Alt b. P2 may be equal to the number of PRBs belonging to RBGs among RBGs (RB Groups) allocated for PUSCH transmission, for RBGs in which all PRBs within the RBG are included in the UL subband.

[0433] Alternatively, P2 may be equal to the number of PRBs belonging to RBGs among the RBGs allocated for PUSCH transmission, for which at least one PRB among the PRBs constituting the RBG is not included in the DL subband and / or the guard subband.

[0434] Alt c. P2 may be equal to the number of RBGs (RB Groups) allocated for PUSCH transmission, in which at least one PRB is included in the UL subband.

[0435] Alternatively, P2 may be equal to the number of PRBs belonging to RBGs among RBGs allocated for PUSCH transmission, for which the total PRBs constituting the RBGs are not included in the DL subband and / or guard subband.

[0436] According to the proposal of the present disclosure, the terminal can operate as follows.

[0437] The terminal determines the time resource for the cell to operate in HD and the time resource for the cell to operate in FD based on the configuration information from the base station.

[0438] Afterwards, when the terminal multiplexes UCI to PUSCH and transmits it in a specific slot n, the terminal uses the proposed method described above to determine the M to be applied for the UCI transmission depending on whether the slot n is an HD slot or an FD slot. PUSCH sc Determine the value of .

[0439] After that, the terminal judged M PUSCH scThe number of coded modulation symbols for each layer for UCI transmission is determined based on the value, and an output bit sequence after rate matching for UCI transmission is obtained according to the number.

[0440] Afterwards, the terminal multiplexes the corresponding output bit sequence into PUSCH transmission in slot n and transmits it to the base station.

[0441] According to the proposal of the present disclosure, the base station can operate as follows.

[0442] The base station determines / determines the resources for the cell to operate as FD and / or HD and signals information about the time resources for the cell to operate as HD and / or FD to the terminal.

[0443] The base station requests UCI information such as HARQ-ACK, CSI, and SR from the terminal and receives this UCI information through PUCCH or PUSCH.

[0444] When the base station receives UCI information from the terminal through PUSCH, the base station uses the proposed method described above to determine M to apply for the corresponding UCI transmission depending on whether the corresponding slot n is an HD slot or an FD slot. PUSCH sc Determine the value of .

[0445] After that, the base station judged M PUSCH sc The number of coded modulation symbols per layer for UCI transmission is determined based on the value, and UCI is received based on that number.

[0446] Figure 18 illustrates the operation method of the terminal.

[0447] Referring to FIG. 18, the terminal generates uplink control information (UCI) (S181).

[0448] The above UCI may include at least one of HARQ-ACK (hybrid automatic repeat request-acknowledgment), CSI (channel state information)-part 1, CSI-part 2, or configured grant (CG)-UCI.

[0449] The terminal transmits the UCI to the network through a physical uplink shared channel (PUSCH) of the slot, and applies a first parameter value to a specific parameter used to determine the number of coded modulation symbols (more specifically, the number of coded modulation symbols per layer) for transmission of the UCI when the slot is an FD slot configured with FD (full duplex) resources, and applies a second parameter value when the slot is an HD slot configured with HD (half duplex) resources (S182).

[0450] For example, if the UCI is HARQ-ACK, the terminal can determine the slot in which to transmit HARQ-ACK information as follows.

[0451] i) DL slot n D In the case of SPS PDSCH reception ending in , the terminal transmits HARQ-ACK information for the SPS PDSCH through the PUCCH of UL slot n+k. At this time, k is provided by the 'PDSCH-to-HARQ_feedback timing indicator' field (if present) of the DCI format that activates the SPS PDSCH reception.

[0452] ii) If the terminal is in DL slot n DWhen a DCI format for activating SPS PDSCH reception or scheduling PDSCH reception ending in is received, but the DCI format does not include a 'PDSCH-to-HARQ feedback timing indicator', the terminal transmits / provides HARQ-ACK information in a PUCCH transmission of UL slot n+k, where k is provided by a higher layer parameter 'dl-DataToUL-ACK', 'dl-DataToUL-ACK-r16', 'dl-DataToUL-ACK-DCI-1-2', 'dl-DataToUL-ACK-r17', 'dl-DataToUL-ACK-DCI-1-2-r17', or 'dl-DataToUL-ACK-v1700'.

[0453] iii) If the terminal is in DL slot n D Receive a DCI format that schedules PDSCH receptions ending in DL slot n, or detect a DCI format that generates HARQ-ACK information bits. D If the UE does not schedule PDSCH reception through PDCCH reception ending in , the UE transmits / provides the corresponding HARQ-ACK information in the PUCCH transmission of UL slot n+k, where k is the number of slots, and is indicated by the 'PDSCH-to-HARQ_feedback timing indicator' field (if any) of the DCI format, or provided by the upper layer parameter 'dl-DataToUL-ACK', 'dl-DataToUL-ACK-r16', 'dl-DataToUL-ACK-DCI-1-2', 'dl-DataToUL-ACK-r17', 'dl-DataToUL-ACK-DCI-1-2-r17', or 'dl-DataToUL-ACK-v1700'.

[0454] An HD slot can be either a downlink (DL) slot, a flexible slot, or an uplink (UL) slot.

[0455] Here, a DL slot may be a slot in which all symbols within the slot are composed of DL symbols, but when a terminal wishes to perform a specific operation (e.g., reception of a DL signal or transmission of a UL signal) in the slot, it may mean a slot in which all symbols for performing the specific operation are composed of DL symbols.

[0456] A UL slot may be a slot in which all symbols within the slot are composed of UL symbols, but when a terminal wishes to perform a specific operation (e.g., transmission of a UL signal or reception of a DL signal) in the slot, it may mean a slot in which all symbols for performing the specific operation are composed of UL symbols.

[0457] A flexible slot may be a slot in which all symbols within the slot are composed of flexible symbols, but when a terminal wishes to perform a specific operation (e.g., transmission of a UL signal or reception of a DL signal) in the slot, it may mean a slot in which all symbols (or at least one symbol) to perform the specific operation are composed of flexible symbols.

[0458] An FD slot may mean a slot in which all symbols within the slot operate as FDs, or may mean a slot in which at least one symbol within the slot operates as an FD. More specifically, an FD slot may mean i) a slot in which all symbol resources for transmitting PUSCH in the slot are symbols operating as FDs, or ii) a slot in which at least one symbol among symbol resources for transmitting PUSCH in the slot is a symbol operating as an FD.

[0459] A symbol / slot operating in HD may be a symbol / slot that the terminal has been semi-statically configured by the base station to operate in HD. A symbol / slot operating in FD may be a symbol / slot that the terminal has been semi-statically configured by the base station to operate in FD. If the terminal is subsequently dynamically instructed by the base station that a specific symbol / slot resource operates in HD or FD, the terminal may determine a slot for transmitting UCI based only on the semi-statically instructed information.

[0460] The above specific parameter is, for example, an offset value (β) that scales the number of resource elements according to the payload size of the UCI. PUSCH offset ) or the above offset value (β PUSCH offset ) may be information indicating the UCI. In this case, if the slot to transmit the UCI is an FD slot, the first parameter value (for convenience, this is β PUSCH offset,1 ) is applied, and if the slot is an HD slot, the second parameter value (for convenience, β PUSCH offset,2 (which can be said to be a) is applied. This has been explained in detail in Proposal 1.

[0461] The payload size of the above UCI is, for example, O if the above UCI is HARQ-ACK. ACK +L ACK It may be, and if the above UCI is CSI Part 1, O CSI-1 +L CSI-1 It may be, and if the above UCI is CSI Part 2, O CSI-2 +L CSI-2 It can be, and if the above UCI is CG-UCI, O CG-UCI +L CG-UCI It can be, and if the above UCI is HARQ-ACK and CG-UCI, O ACK +O CG-UCI +L ACKIt can be. For this, refer to Equations 1 to 5.

[0462] The above specific parameter may be, for example, information (i.e., α (alpha)) related to setting an upper bound of the number of resource elements that can transmit the UCI. In this case, if the slot to transmit the UCI is an FD slot, the first parameter value (e.g., the above-described α) HD ) is applied, and if the slot is an HD slot, the second parameter value (e.g., the aforementioned α HD +W, or α HD ·W) is applied. This is explained in detail in Proposal 2.

[0463] The above specific parameter is, for example, a value (M) expressed as the number of subcarriers for the scheduled bandwidth of the PUSCH transmission. PUSCH sc ) may be. In this case, if the slot to transmit the UCI is an FD slot, the first parameter value (e.g., the above-described P1·N RB sc ) is applied, and if the slot is an HD slot, the second parameter value (e.g., the above-mentioned P2·N RB sc ) is applied. Here, P1 is the number of physical resource blocks (PRBs) allocated for the PUSCH transmission, and N RB sc is the number of subcarriers per resource block, and P2 is the number of PRBs included in the uplink subband among the P1 PRBs. This has been explained in detail in Proposal 3.

[0464] The above specific parameter is, for example, the maximum PUCCH coding rate (R) for transmission of the UCI. max UCI) or the maximum PUCCH coding rate (R max UCI ) may be information that informs you of this. For this, see below. <UCI가 PUCCH로 전송되는 경우의 레이트 매칭 출력 시퀀스의 길이(the length of rate matching output sequence)> It is explained in detail in .

[0465] The above specific parameter may have different values ​​depending on the type of UCI. For example, the above specific parameter may be β PUSCH offset When the UCI is HARQ-ACK, β HARQ-ACK offset,1 , β HARQ-ACK offset,2 can be applied depending on the type of UCI transmission slot (whether it is an HD slot or an FD slot). If the UCI is CSI Part 1, β CSI-1 offset,1 , β CSI-1 offset,2 can be applied depending on the type of UCI transmission slot. If the UCI is CSI Part 2, β CSI-2 offset,1 , β CSI-2 offset,2 It can be applied depending on the type of UCI transmission slot.

[0466] The terminal can semi-statically receive / provide / set, through a higher layer signal, a first parameter value applicable when the slot to transmit UCI is an FD slot and a second parameter value applicable when the slot is an HD slot, for the specific parameter.

[0467] The terminal can dynamically receive / provide / set, through downlink control information (DCI), the first parameter value applied when the slot to transmit UCI is an FD slot and the second parameter value applied when the slot is an HD slot, for the specific parameter.

[0468] The second parameter value may be determined based on the first parameter value and one of i) a predetermined value and ii) a value set from the network.

[0469] According to the method according to the present disclosure, when UCI is multiplexed and transmitted on a PUSCH in an FD resource that may have a channel condition worse than the channel condition targeted by the base station, a code rate suitable for the FD resource can be applied, so that UCI can be transmitted reliably.

[0470] In addition, when UCI is transmitted through different types of resources, ambiguity can be prevented by clarifying the value of the parameter used to determine the number of coded modulation symbols of the UCI.

[0471] Figure 19 illustrates the signaling process and operation between a base station and a terminal.

[0472] Referring to FIG. 19, the base station provides the terminal with configuration information indicating HD resources and / or FD resources (S191). For example, the base station may determine / decide whether the cell operates as an FD resource and / or an HD resource, and signal information about the time resources for the cell to operate as an HD resource and / or an FD resource to the terminal.

[0473] The base station may request UCI from the terminal (S192). For example, the base station may request at least one of HARQ-ACK, CSI, and SR from the terminal. However, this process may not be mandatory. For example, the terminal may transmit HARQ-ACK to the base station even if the base station does not explicitly request HARQ-ACK from the terminal.

[0474] The terminal applies a first parameter value or a second parameter value as a value of a specific parameter used to determine the number of coded modulation symbols for UCI transmission (e.g., the number of coded modulation symbols per layer), considering whether the slot for transmitting UCI is an FD slot or an HD slot (S193).

[0475] When a base station receives UCI information from a terminal through a PUSCH of a specific slot, the base station can also use the proposed method described above to determine which of the first parameter value and the second parameter value is applied as the value of the specific parameter depending on whether the specific slot is an HD slot or an FD slot.

[0476] The terminal transmits UCI to the base station in the above slot (S194).

[0477] <UCI가 PUCCH로 전송되는 경우의 레이트 매칭 출력 시퀀스의 길이(the length of rate matching output sequence)>

[0478] The input bit sequence for rate matching is can be expressed as . Here, r is the code block number, and N r is the number of coded bits of code block number r. At this time, the length of the rate matching output sequence of UCI when UCI is transmitted on PUCCH (E UCI ) can be determined as shown in the following table.

[0479] [Table 8]

[0480]

[0481] Rate matching is the rate matching output sequence length E r =floor(E UCI / C UCI ) can be set to . Here, C UCI is the number of code blocks for UCI and E UCI The values ​​are shown in Table 8. Floor(x) represents the largest integer less than or equal to x.

[0482] In Table 8, O ACK is the number of bits of HARQ-ACK to be transmitted on the current PUCCH. O SR is the number of bits of SR to be transmitted on the current PUCCH. O CSI-part1 is the number of bits of CSI Part 1 to be transmitted on the current PUCCH. O CSI-part2 is the number of bits of CSI Part 2 to be transmitted on the current PUCCH.

[0483] If A is greater than or equal to 360, L is 11. Otherwise, L is the number of CRC bits. A is O for "CSI (CSI of two parts)". CSI-part1 , and O for "HARQ-ACK, CSI (CSI of two parts)" ACK +O CSI-part1 , and O for "HARQ-ACK, SR, CSI (CSI of two parts)" ACK +O SR +O CSI-part1 It is the same as .

[0484] R max UCI is the configured maximum PUCCH coding rate.

[0485] E tot is given by Table 8.

[0486] After rate matching, the output bit sequence is It can be expressed as follows. Here, E r is the length of the rate-matching output sequence in code block number r.

[0487] The terminal may set the code rate for multiplexing HARQ-ACK, SR, and CSI reports in PUCCH transmission using PUCCH format 2, PUCCH format 3, or PUCCH format 4 by 'maxCodeRate'.

[0488] The configured maximum PUCCH coding rate is R max UCI The value can be set by the upper layer parameter 'maxCodeRate' as follows:

[0489] [Table 9]

[0490]

[0491] In the present disclosure, when a terminal transmits UCI through PUCCH in a cell performing FD operation, the maximum PUCCH coding rate (R) for UCI transmission is determined according to the time resource when the cell operates as FD and the time resource when the cell operates as HD. max UCI ) suggests a different way to judge it.

[0492] HD slots and FD slots may more specifically refer to:

[0493] An HD slot may mean a slot in which all symbols within the slot operate as HD. An FD slot may mean a slot in which all symbols within the slot operate as FD, or a slot in which at least one symbol within the slot operates as FD.

[0494] Alternatively, an HD slot may refer to a slot in which all symbol resources for transmitting PUSCH in the slot are composed of symbols operating in HD. On the other hand, an FD slot may refer to a slot in which all symbol resources for transmitting PUSCH in the slot are symbols operating in FD, or a slot in which at least one symbol among symbol resources for transmitting PUSCH in the slot is a symbol operating in FD.

[0495] In the present disclosure, a symbol / slot operating in HD may refer to a symbol / slot for which a base station has semi-statically configured the terminal to operate in HD. In the present disclosure, a symbol / slot operating in FD may refer to a symbol / slot for which a base station has semi-statically configured the terminal to operate in FD. Thereafter, when a terminal is dynamically instructed by the base station that a specific symbol / slot resource operates in HD or FD, the terminal may determine a slot for transmitting UCI by considering only the semi-statically instructed information.

[0496] The terminal applies R to the HD slot and FD slot as follows: max UCI The value of can be judged differently.

[0497] Option 1. The terminal applies RRC signaling for HD slots and FD slots from the base station. max UCI The value of is independently instructed. To this end, the terminal can independently set the 'maxCodeRate' value applied to the HD slot and the FD slot through upper layer signaling from the base station. In this case, if the slot transmitting the UCI is an HD slot, the terminal applies the 'maxCodeRate' information applied to the HD slot to set the R max UCIThe value of can be determined. Or, if the slot transmitting UCI is an FD slot, the 'maxCodeRate' information applied to the FD slot can be applied to R max UCI The value of can be judged.

[0498] Option 2. The terminal applies R according to the 'maxCodeRate' value instructed through RRC signaling from the base station. max UCI The value may be interpreted / judged differently for HD slots and FD slots.

[0499] For example, the value indicated through 'maxCodeRate' is R max UCI,HD When R, the terminal transmits UCI if the slot is an HD slot. max UCI,HD R, which applies the value to the terminal max UCI It can be judged by value. On the other hand, if the slot transmitting the UCI is an FD slot, R max UCI,HD +U or R max UCI,HD R to which the terminal applies the ХU value max UCI It can be judged by value.

[0500] At this time, the U value may be fixed / defined to a specific value by the standard specification. Alternatively, the U value may be information set / indicated by the terminal from the base station through RRC / MAC-CE / DCI signaling, etc.

[0501] According to the proposal of the present disclosure, the terminal can operate as follows.

[0502] The terminal determines the time resource for the cell to operate in HD and the time resource for the cell to operate in FD based on the configuration information from the base station.

[0503] Afterwards, when the terminal transmits UCI through PUCCH in a specific slot n, the terminal uses the proposed method described above to determine R to be applied for the UCI transmission depending on whether the slot n is an HD slot or an FD slot. max UCI Determine the value of .

[0504] After that, the terminal judged R max UCI Based on the value, the rate matching output sequence length for UCI transmission is determined, and an output bit sequence after rate matching for UCI transmission is obtained according to the corresponding number.

[0505] Afterwards, the terminal transmits the corresponding output bit sequence to the base station through PUCCH in slot n.

[0506] According to the proposal of the present disclosure, the base station can operate as follows.

[0507] The base station determines / determines the resources for the cell to operate as FD and / or HD and signals information about the time resources for the cell to operate as HD and / or FD to the terminal.

[0508] The base station requests UCI information such as HARQ-ACK, CSI, and SR from the terminal and receives this UCI information through PUCCH or PUSCH.

[0509] When the base station receives UCI information from the terminal through PUCCH, the base station uses the proposed method described above to determine R to apply for the corresponding UCI transmission depending on whether the corresponding slot n is an HD slot or an FD slot. max UCI Determine the value of .

[0510] After that, the base station judged R max UCIThe rate matching output sequence length for UCI transmission is determined based on the value, and the UCI is received based on the corresponding number.

[0523] Fig. 21 illustrates an example of a signal processing module structure. Here, signal processing may be performed in the processor (102, 202) of Fig. 20.

[0524] Referring to FIG. 21, 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).

[0525] 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.

[0526] 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.

[0527] 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.

[0528] 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.

[0529] 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.

[0530] Fig. 22 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. 20.

[0531] Referring to FIG. 22, 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).

[0532] 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).

[0533] 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.

[0534] The above complex modulation symbol can be mapped to one or more transmission layers by the layer mapper (403).

[0535] 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.

[0536] 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.

[0537] The resource block mapper (405) can assign complex modulation symbols to appropriate subcarriers and multiplex them according to the user.

[0538] 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.

[0539] 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.

[0550] The difference between the example of the wireless device described in FIG. 20 and the example of the wireless device in FIG. 24 is that in FIG. 20, the processor (102, 202) and the memory (104, 204) are separated, but in the example of FIG. 24, the memory (104, 204) is included in the processor (102, 202). That is, the processor and the memory may constitute a single chipset.

[0551] Fig. 25 illustrates a communication system (1) applied to this specification.

[0552] Referring to FIG. 25, a communication system (1) applied to the present specification includes a wireless device, a base station, and a network. Here, the wireless device refers to a device that performs communication using a wireless access technology (e.g., 5G NR (New RAT), LTE (Long Term Evolution)) and may be referred to as a communication / wireless / 5G device. Although not limited thereto, the wireless device may include a robot (100a), a vehicle (100b-1, 100b-2), an XR (eXtended Reality) device (100c), a hand-held device (100d), a home appliance (100e), an IoT (Internet of Things) device (100f), and an AI device / server (400). For example, the vehicle may include a vehicle equipped with a wireless communication function, an autonomous vehicle, a vehicle capable of performing vehicle-to-vehicle communication, etc. Here, the vehicle may include an Unmanned Aerial Vehicle (UAV) (e.g., a drone). XR devices include AR (Augmented Reality) / VR (Virtual Reality) / MR (Mixed Reality) devices, and can be implemented in the form of HMD (Head-Mounted Device), HUD (Head-Up Display) installed in a vehicle, television, smartphone, computer, wearable device, home appliance, digital signage, vehicle, robot, etc. Mobile devices can include smartphone, smart pad, wearable device (e.g., smart watch, smart glass), computer (e.g., laptop, etc.), etc. Home appliances can include TV, refrigerator, washing machine, etc. IoT devices can include sensors, smart meters, etc. For example, base stations and networks can also be implemented as wireless devices, and a specific wireless device (200a) can act as a base station / network node to other wireless devices.

[0553] Wireless devices (100a to 100f) can be connected to a network (300) via a base station (200). 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. For example, vehicles (100b-1, 100b-2) can communicate directly (e.g., V2V (Vehicle to Vehicle) / V2X (Vehicle to Everything) communication). In addition, IoT devices (e.g., sensors) can communicate directly with other IoT devices (e.g., sensors) or other wireless devices (100a to 100f).

[0554] Wireless communication / connection (150a, 150b, 150c) can be established between wireless devices (100a~100f) / base stations (200), and base stations (200) / base stations (200). Here, wireless communication / connection can be achieved through various wireless access technologies (e.g., 5G NR) such as uplink / downlink communication (150a), sidelink communication (150b) (or, D2D communication), and communication between base stations (150c) (e.g., relay, IAB (Integrated Access Backhaul). Through wireless communication / connection (150a, 150b, 150c), wireless devices and base stations / wireless devices, and base stations and base stations can transmit / receive wireless signals to each other. For example, wireless communication / connection (150a, 150b, 150c) can transmit / receive signals through various physical channels. To this end, at least some of various configuration information setting processes for transmitting / receiving wireless signals, various signal processing processes (e.g., channel encoding / decoding, modulation / demodulation, resource mapping / demapping, etc.), and resource allocation processes can be performed based on various proposals of the present specification.

[0555] Meanwhile, NR supports multiple numerologies (or subcarrier spacing (SCS)) to support various 5G services. For example, an SCS of 15 kHz supports a wide area in traditional cellular bands; an SCS of 30 kHz / 60 kHz supports dense urban areas, lower latency, and wider carrier bandwidth; and an SCS of 60 kHz or higher supports a bandwidth greater than 24.25 GHz to overcome phase noise.

[0556] 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 10 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).

[0557] [Table 10]

[0558]

[0559] 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 11 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).
