Description

[Technical Field]

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

[0002] As more communication devices demand greater communication capacity, the need for improved mobile broadband communication compared to 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, are also major issues to consider in next-generation communications. In addition, communication system designs that take into account reliability and latency-sensitive services / terminals are being discussed. Thus, the introduction of next-generation wireless connectivity technologies that consider enhanced mobile broadband communication, massive MTC, and URLLC (Ultra-Reliable and Low Latency Communication) is being discussed, and for convenience, this disclosure refers to these technologies as new RAT or NR.

[0003] NR and later wireless communication systems can perform full duplex (FD) operation. When performing FD operation, the device can perform downlink reception and uplink transmission simultaneously using a given time resource. Half duplex (HD) operation differs from FD operation in that only one of downlink reception or uplink transmission can be performed using a given time resource. For FD operation, i) some frequency resources can be allocated to the downlink subband and other frequency resources to the uplink subband within the same time resource (this is called subband FD, or SBFD (subband-wise full duplex)), or ii) frequency resources can be allocated that can be used for both downlink reception and uplink transmission within the same time resource (this is called spectrum-shared FD, or SSFD (spectrum-sharing full duplex)).

[0004] To improve communication reliability and / or increase coverage, specific channels can be transmitted repeatedly. For example, a physical uplink shared channel (PUSCH), which is an uplink data channel, can also be transmitted repeatedly across multiple slots.

[0005] However, when a PUSCH transmission occurs, the size of the transport block (TB) transmitted via PUSCH is determined based on the number of physical resource blocks (PRBs) allocated for the PUSCH transmission. If the time-domain resources used for repeated PUSCH transmissions include both FD slots that operate on FDs and slots that do not operate on FDs, such as HD slots that operate on HDs, the number of PRBs used for PUSCH transmissions in each slot may differ from one another.

[0006] Conventional technology assumes that the time-domain resources used for PUSCH repetitive transmission contain slots of the same type. However, there is a problem in that there is no clear method for determining the Time-Block Size (TBS) in PUSCH repetitive transmission when the slots are of different types. Therefore, a method is needed to determine the TB size in PUSCH repetitive transmission when the slots are of different types. [Overview of the project] [Problems that the invention aims to solve]

[0007] The technical problem that this disclosure aims to solve is to provide a method for operating a device in a wireless communication system and a device using the said method. [Means for solving the problem]

[0008] The present invention provides a method for operating a device in a wireless communication system and a device using the said method. According to the said method, a terminal determines the size of a transport block (TB) and transmits the TB having the said size via a physical uplink shared channel (PUSCH) in each of the multiple slots. At this time, the multiple slots include (equip; configure; construct; set up; include; contain; contain; have) FD (full duplex) slots that can simultaneously perform uplink and downlink operations using different frequency bands within the slot, and HD (half duplex) slots that can perform uplink or downlink operations within the slot, and the said size is determined based on the total number of resource elements allocated for PUSCH (N) which is determined based on the physical resource blocks (PRB) transmitted in the HD slot. RE It is determined based on the value obtained by applying the scaling factor to ).

[0009] In other respects, the present invention provides a recording medium that can be read by a terminal, device, and computer performing the aforementioned method.

[0010] In other aspects, the present invention provides a method for operating a base station and a base station using the method. According to the method for operating the base station, the base station transmits scheduling information to a terminal for scheduling uplink transmissions, and based on the scheduling information, receives transport blocks (TB) having a specific transport block size (TBS) from the terminal via a physical uplink sharing channel (PUSCH) in each of a plurality of slots. The plurality of slots includes FD (full duplex) slots that can simultaneously perform uplink and downlink operations using different frequency bands within the slot, and HD (half duplex) slots that can perform uplink or downlink operations within the slot, wherein the TBS is determined based on the total number of resource elements allocated for PUSCH (N) which is determined based on the physical resource blocks (PRB) transmitted in the HD slot. RE It is determined based on the value obtained by applying the scaling factor to ). [Effects of the Invention]

[0011] According to the method of this disclosure, when a PUSCH repetition transmission is transmitted across slots of different types in the time domain, for example, a mix of FD slots and HD slots, the TBS can be determined to reflect the frequency domain resources actually used in each slot, thereby reducing the probability of errors.

[0012] Furthermore, if the PUSCH repeat transmissions are transmitted across different types of slots in the time domain, this prevents ambiguity in how the TBS (Time-Based Sentence) is determined. [Brief explanation of the drawing]

[0014] In this specification, "A or B" may mean "A only," "B only," or "both A and B." In other words, in this specification, "A or B" may be interpreted as "A and / or B." For example, in this specification, "A, B or C" may mean "A only," "B only," "C only," or "any combination of A, B and C."

[0015] In this specification, slashes ( / ) and commas may mean "and / or". For example, "A / B" may mean "A and / or B". Thus, "A / B" may mean "A only", "B only", or "both A and B". For example, "A, B, C" may mean "A, B or C".

[0016] In this specification, "at least one of A and B" may mean "A only," "B only," or "both A and B." Furthermore, in this specification, the expressions "at least one of A or B" and "at least one of A and / or B" may be interpreted similarly to "at least one of A and B."

[0018] Furthermore, parentheses used in this specification may mean "for example." Specifically, when "control information (PDCCH)" is indicated, "PDCCH" may be proposed as an example of "control information." In other words, "control information" in this specification is not limited to "PDCCH," and "PDCCH" may be proposed as an example of "control information." Also, when "control information (i.e., PDCCH)" is indicated, "PDCCH" may be proposed as an example of "control information."

[0019] Technical features described individually within a single drawing in this specification may be implemented individually or simultaneously.

[0020] Figure 1 illustrates a wireless communication system to which this disclosure may apply. This is also known as E-UTRAN (Evolved-UMTS Terrestrial Radio Access Network) or LTE (Long Term Evolution) / LTE-A system.

[0021] E-UTRAN includes a base station (BS) 20 that provides a control plane and a user plane to a terminal (User Equipment, UE) 10. The terminal 10 may be fixed or mobile and may be referred to by other terms such as MS (Mobile station), UT (User Terminal), SS (Subscriber Station), MT (mobile terminal), Wireless Device, or terminal. The base station 20 is a fixed station that communicates with the terminal 10 and may be referred to by other terms such as eNB (evolved-NodeB), BTS (Base Transceiver System), or Access Point.

[0022] The base stations 20 can be connected to each other via the X2 interface. The base stations 20 are connected to the EPC (Evolved Packet Core) 30 via the S1 interface, more specifically to the MME (Mobility Management Entity) via S1-MME, and to the S-GW (Serving Gateway) via S1-U.

[0023] EPC30 consists of an MME, S-GW, and P-GW (Packet Data Network-Gateway). The MME holds information about terminal connectivity and terminal capabilities, and this information is primarily used for terminal mobility management. The S-GW is a gateway with E-UTRAN as its termination point, and the P-GW is a gateway with PDN as its termination point.

[0024] The layers of the Radio Interface Protocol (RRC) between a terminal and a network can be divided into L1 (First Layer), L2 (Second Layer), and L3 (Third Layer) based on the three lower layers of the Open System Interconnection (OSI) standard model, which is widely known in communication systems. Of these, the physical layer, which belongs to the first layer, provides information transfer services using physical channels, while the RRC (Radio Resource Control) layer, located in the third layer, plays the role of controlling radio resources between the terminal and the network. For this purpose, the RRC layer exchanges RRC messages between the terminal and the base station.

[0025] Figure 2 is a block diagram showing the radio protocol architecture for the user plane. Figure 3 is a block diagram showing the radio protocol architecture for the control plane. The user plane is the protocol stack for transmitting user data, and the control plane is the protocol stack for transmitting control signals.

[0026] Referring to Figures 2 and 3, the physical layer (PHY (physical) layer) provides information transfer services to higher layers using physical channels. The physical layer is connected to the higher layer, the MAC (Medium Access Control) layer, via transport channels. Data moves between the MAC layer and the physical layer via transport channels. Transport channels are classified according to how and with what characteristics data is transmitted via the wireless interface.

[0027] Data travels between different physical layers, specifically between the transmitter and receiver, via a physical channel. This physical channel can be modulated using OFDM (Orthogonal Frequency Division Multiplexing), utilizing time and frequency as wireless resources.

[0028] The MAC hierarchy's functionality includes mapping between logical channels and transport channels, and multiplexing / demultiplexing of MAC SDUs (service data units) belonging to logical channels into transport blocks provided to physical channels on the transport channels. The MAC hierarchy provides services to the RLC (Radio Link Control) hierarchy via logical channels.

[0029] The RLC hierarchy's functions include concatenation, segmentation, and reassembly of RLC SDUs. To ensure the diverse Quality of Service (QoS) requirements of radio bearers (RBs), the RLC hierarchy provides three operating modes: Transparent Mode (TM), Unacknowledged Mode (UM), and Acknowledged Mode (AM). AM RLC provides error correction via ARQ (automatic repeat request).

[0030] The RRC (Radio Resource Control) hierarchy is defined only in the control plane. The RRC hierarchy is responsible for controlling logical channels, transport channels, and physical channels in connection with the configuration, reconfiguration, and release of radio bearers. RB refers to the logical paths provided by the first layer (PHY layer) and the second layer (MAC layer, RLC layer, PDCP layer) for data transmission between the terminal and the network.

[0031] The functions of the PDCP (Packet Data Convergence Protocol) layer on the user plane include the transmission of user data, header compression, and encryption (ciphering). The functions of the PDCP (Packet Data Convergence Protocol) layer on the control plane include the transmission of control plane data and encryption / integrity protection.

[0032] Setting up a Radio Protocol (RB) refers to the process of defining the characteristics of the radio protocol hierarchy and channels in order to provide a specific service, and setting the specific parameters and operating methods for each. RBs are further divided into two types: SRB (Signaling RB) and DRB (Data RB). SRBs are used as channels for transmitting RRC messages in the control plane, while DRBs are used as channels for transmitting user data in the user plane.

[0033] If an RRC connection is established between the terminal's RRC hierarchy and the E-UTRAN's RRC hierarchy, the terminal enters an RRC connected state; otherwise, it enters an RRC idle state.

[0034] Downlink transport channels, which transmit data from the network to terminals, include BCH (Broadcast Channel) for transmitting system information and Downlink SCH (Shared Channel) for transmitting user traffic and control messages. Downlink multicast or broadcast service traffic or control messages can be transmitted via Downlink SCH or via a separate Downlink MCH (Multicast Channel). On the other hand, uplink transport channels, which transmit data from terminals to the network, include RACH (Random Access Channel) for transmitting initial control messages and Uplink SCH (Shared Channel) for transmitting user traffic and control messages.

[0035] Above the transport channel, logical channels 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).

[0036] A physical channel consists of multiple OFDM symbols in the time domain and multiple subcarriers in the frequency domain. A 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. Each subframe can also use a specific subcarrier of a specific OFDM symbol (e.g., the first OFDM symbol) for the PDCCH (Physical Downlink Control Channel), i.e., the L1 / L2 control channel. The Transmission Time Interval (TTI) is the unit time for subframe transmission.

[0037] The following explains new radio access technology (new RAT, NR).

[0038] As more and more communication devices demand even larger communication capacities, the need for improved mobile broadband communication compared to conventional radio access technology (RAT) is emerging. Massive Machine Type Communications (MTC), which connects numerous devices and things to provide diverse services anytime, anywhere, is also one of the key issues being considered in next-generation communications. Furthermore, communication system designs that take into account reliability and latency-sensitive services / terminals are being discussed. Thus, the introduction of next-generation radio connectivity technologies that consider enhanced mobile broadband communication, massive MTC, and URLLC (Ultra-Reliable and Low Latency Communication) is being discussed, and for convenience, this disclosure refers to these technologies as new RAT or NR.

[0039] Figure 4 illustrates the system structure of a next-generation radio access network (NG-RAN) to which NR is applied.

[0040] Referring to Figure 4, the NG-RAN can include gNBs and / or eNBs that provide user plane and control plane protocol termination to terminals. Figure 4 illustrates the 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 NG interfaces. More specifically, they are connected to the AMF (access and mobility management function) via the NG-C interface and to the UPF (user plane function) via the NG-U interface.

[0041] Figure 5 illustrates the functional division between NG-RAN and 5GC.

[0042] Referring to Figure 5, gNB provides functions such as inter-cell radio resource management (Inter Cell RRM), radio bearer management (RB control), connection mobility control, radio admission control, measurement configuration and provision, and dynamic resource allocation. AMF provides functions such as NAS security and idle state mobility processing. UPF provides functions such as mobility anchoring and PDU processing. SMF (Session Management Function) provides functions such as terminal IP address assignment and PDU session control.

[0043] Figure 6 illustrates a frame structure that can be applied in NR.

[0044] Referring to Figure 6, in NR, radio frames (hereinafter abbreviated as frames) can be used for uplink and downlink transmission. A frame has a length of 10 ms and can be defined as two 5 ms half-frames (HF). A half-frame can be defined as five 1 ms subframes (SF). A subframe can be divided into one or more slots, and the number of slots within a subframe depends on SCS (Subcarrier Spacing). Each slot contains 12 or 14 OFDM(A) symbols by a cyclic prefix (CP). 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 OFDM symbols (or CP-OFDM symbols) and SC-FDMA symbols (or DFT-s-OFDM symbols).

[0045] Table 1 below shows examples of subcarrier spacing configurations (also called subcarrier spacing settings) μ.

[0046] [Table 1]

[0047] Table 2 below shows the number of slots (N) in a frame, depending on the subcarrier spacing configuration μ. frame,μ slot ), number of slots in the subframe (N subframe,μ slot ), number of symbols in the slot (N slot symb Examples include:

[0048] [Table 2]

[0049] Figure 6 shows examples for μ = 0, 1, 2, and 3.

[0050] Table 2-1 below illustrates how the number of symbols per slot, the number of slots per frame, and the number of slots per subframe change depending on the SCS when an extended CP is used.

[0051] [Table 2-1]

[0052] In an NR system, OFDM(A) numerology (e.g., SCS, CP length, etc.) can be configured to differ between multiple cells merged into a single terminal. This allows the (absolute time) intervals of time resources (e.g., SF, slots, or TTI) (commonly referred to as TU (Time Unit) for convenience), which consist of the same number of symbols, to be configured differently between the merged cells.

[0053] Figure 7 illustrates a slot structure.

[0054] 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), and in the case of an extended CP, one slot can contain 12 symbols (or 6 symbols). A carrier wave can contain multiple subcarriers in the frequency domain. An RB (Resource Block) can be defined as multiple (e.g., 12) consecutive subcarriers in the frequency domain. A BWP (Bandwidth Part) 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 wave can contain up to N (e.g., 5) BWPs. Data communication is performed via activated BWPs, and only one BWP can be activated per terminal. In a resource grid, each element is called a Resource Element (RE) and can be mapped to a single complex symbol.

[0055] A PDCCH (physical downlink control channel) can be composed of one or more CCEs (control channel elements) as shown in Table 3 below.

[0056] [Table 3]

[0057] In other words, PDCCH is transmitted via a resource consisting of 1, 2, 4, 8, or 16 CCEs. Here, a CCE consists of 6 REGs (resource element groups), and each REG consists of one resource block in the frequency domain and one OFDM (orthogonal frequency division multiplexing) symbol in the time domain.

[0058] Monitoring means decoding each PDCCH candidate according to a DCI (downlink control information) format. The terminal monitors a set of PDCCH candidates in one or more core sets (CORESET, described below) on the activated DL BWP of each activated serving cell for which PDCCH monitoring is configured, according to the corresponding search space set.

[0059] In NR, a new unit called a control resource set (CORESET) can be introduced. The terminal can receive PDCCH in the core set.

[0060] Figure 8 illustrates the core set.

[0061] Referring to Figure 8, the core set is composed of N resource blocks in the frequency domain and can be composed of N ∈ {1, 2, 3} symbols in the time domain. N, N can be provided by the base station via a higher layer signal. As shown in Figure 7, a plurality of CCEs (or REGs) can be included in the core set. CORESET RB 個のリソースブロックで構成され、時間領域でN CORESET symb ∈{1, 2, 3} symbols in the time domain. N, N can be provided by the base station via a higher layer signal. As shown in Figure 7, a plurality of CCEs (or REGs) can be included in the core set. CORESET RB 、N CORESET symb can be provided by the base station via a higher layer signal. As shown in Figure 7, a plurality of CCEs (or REGs) can be included in the core set.

[0062] The terminal can attempt to detect PDCCH in units of 1, 2, 4, 8 or 16 CCEs within the core set. One or more CCEs that can attempt to detect PDCCH can be called PDCCH candidates.

[0063] The terminal can receive settings of multiple core sets.

[0064] In conventional wireless communication systems (e.g., LTE / LTE-A), the control domain was configured across the entire system bandwidth used by the base station. All terminals, with the exception of some terminals supporting only narrow bandwidths (e.g., eMTC / NB-IoT terminals), needed to be able to receive radio signals across the entire system bandwidth of the base station in order to accurately receive / decode the control information transmitted by the base station.

[0065] In contrast, NR introduced the aforementioned core set. A core set can be described as a radio resource for control information that a terminal should receive, and in the frequency domain, it can use only a portion of the system bandwidth instead of the entire system bandwidth. Also, in the time domain, it can use only a portion of the symbols within a slot. A 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 base station control information without necessarily receiving the entire system bandwidth.

[0066] The core set includes a terminal-specific core set for transmitting terminal-specific control information and a common core set for transmitting control information common to all terminals.

[0067] On the other hand, in NR, high reliability may be required depending on the application field, and in such situations, the target block error rate (BLER) for DCI (downlink control information) transmitted via a downlink control channel (e.g., physical downlink control channel: PDCCH) can be significantly lower than in conventional technologies. One way to meet this requirement for 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 the following: resources in the time domain, resources in the frequency domain, resources in the code domain, and resources in the spatial domain.

[0068] The following technologies / features can be applied to NR.

[0069] <Self-contained subframe structure>

[0070] Figure 9 shows an example of a frame structure for a new wireless connectivity technology.

[0071] In NR, to minimize latency, one frame structure is considered in which the control channel and data channel are time-division multiplexed (TDM) within a single TTI, as shown in Figure 8.

[0072] In Figure 9, the shaded area represents the downlink control area, and the black area represents the uplink control area. Areas without a label may be used for downlink data (DL data) transmission or for uplink data (UL data) transmission. A key feature of this structure is that downlink (DL) transmission and uplink (UL) transmission proceed sequentially within a single subframe, allowing DL data to be sent and UL ACK / NACK (Acknowledgement / Not-acknowledgement) to be received within the subframe. As a result, the time required for data retransmission in the event of a data transmission error is reduced, thus minimizing the latency of the final data transmission.

[0073] In such a data and control TDM-enabled subframe structure, a time gap is required for the transition between the base station and the terminal from transmit mode to receive mode, or from receive mode to transmit mode. For this reason, in a self-contained subframe structure, some OFDM symbols at the time of conversion from DL to UL are set in a guard period (GP).

[0074] Figure 10 illustrates the structure of a self-contained slot.

[0075] In an NR system, a single slot can contain a DL control channel, DL or UL data, and a UL control channel. For example, the first N symbols in a slot can be used when transmitting a DL control channel (hereinafter referred to as the DL control area), and the last M symbols in the slot can be used when transmitting a UL control channel (hereinafter referred to as the UL control area). N and M are integers greater than or equal to 0. The resource area (hereinafter referred to as the data area) between the DL control area and the UL control area can be used for transmitting DL data or UL data. As an example, the following configuration can be considered. Each section is listed in chronological order.

[0076] 1.DL only configuration

[0077] 2.UL only configuration

[0078] 3.Mixed UL-DL configuration

[0079] -DL area + GP (Guard Period) + UL control area

[0080] -DL control area + GP + UL area

[0081] DL area: (i) DL data area, (ii) DL control area + DL data area

[0082] UL area: (i) UL data area, (ii) UL data area + UL control area

[0083] In the DL control domain, PDCCH can be transmitted, and in the DL data domain, PDSCH (physical downlink shared channel) can be transmitted. In the UL control domain, PUCCH (physical uplink control channel) can be transmitted, and in the UL data domain, PUSCH (physical uplink shared channel) can be transmitted. PDCCH can transmit DCI (Downlink Control Information), such as DL data scheduling information and UL data scheduling information. PUCCH can transmit UCI (Uplink Control Information), such as ACK / NACK (Positive Acknowledgement / Negative Acknowledgement) information for DL ​​data, CSI (Channel State Information) information, and SR (Scheduling Request). GP provides a time gap during the transition between the base station and the terminal from transmit mode to receive mode, or from receive mode to transmit mode. Some symbols at the point of transition from DL to UL within a subframe can be set in GP.

[0084] <Analog beamforming #1>

[0085] In millimeter waves (mmW), the wavelength is shorter, allowing for the placement of multiple antenna elements in the same area. Specifically, in the 30 GHz band, with a wavelength of 1 cm, a total of 100 antenna elements can be installed in a 5x5 cm panel at 0.5 wavelength (lambda) intervals in a two-dimensional array. Therefore, in mmW, the aim is to increase beamforming gain and thus coverage, or to increase throughput, by using a large number of antenna elements.

[0086] In this case, if each antenna element has its own transceiver unit (TXRU) that allows for independent beamforming based on frequency resources, then independent beamforming is possible for each frequency resource. However, installing a TXRU for all 100+ antenna elements presents a cost-ineffective problem. Therefore, a method is being considered in which multiple antenna elements are mapped to a single TXRU and the beam direction is adjusted using an analog phase shifter. Such an analog beamforming method has the disadvantage that it can only form one beam direction across the entire bandwidth and cannot perform frequency-selective beamforming.

[0087] As an intermediate form between digital beamforming (Digital BF) and analog beamforming (analog BF), hybrid beamforming (hybrid BF) can be considered, which has B TXRUs, fewer than Q antenna elements. In this case, although there will be differences depending on the coupling method of the B TXRUs and Q antenna elements, the number of beam directions that can be transmitted simultaneously will be limited to B or less.

[0088] <Analog beamforming #2>

[0089] In NR systems where numerous antennas are used, hybrid beamforming techniques combining digital and analog beamforming are gaining prominence. In this case, analog beamforming (or RF beamforming) has the advantage of performing precoding (or combining) at the RF end, thereby reducing the number of RF chains and D / A (or A / D) converters, while achieving performance close to that of digital beamforming. For convenience, the aforementioned hybrid beamforming structure can be represented by N TXRUs and M physical antennas. In this case, digital beamforming for L data layers transmitted at the transmitting end can be represented by an NbyL matrix, and thereafter, the N digital signals are converted to analog signals via the TXRUs, after which analog beamforming represented by an MbyN matrix is ​​applied.

[0090] NR system information can be transmitted via broadcasting. In this case, analog beams belonging to different antenna panels within a single symbol can be transmitted simultaneously, and a beam reference signal (BRS) is being discussed, which is a reference signal (RS) to which a single analog beam (corresponding to a specific antenna panel) is applied and transmitted to measure different analog beam channels. The BRS can be defined for multiple antenna ports, and each antenna port of the BRS can correspond to a single analog beam. In this case, unlike the BRS, the synchronization signal (xPBCH) can be transmitted using all analog beams within an analog beam group so that any terminal can easily receive it.

[0091] In NR, a synchronization signal block (SSB, or synchronization signal and physical broadcast channel: SS / PBCH) in the time domain can consist of four OFDM symbols numbered in ascending order from 0 to 3 within the synchronization signal block, and the primary synchronization signal (PSS), secondary synchronization signal (SSS), demodulation reference signal (DMRS), and associated PBCH can be mapped to these symbols. As mentioned above, a synchronization signal block can also be represented as an SS / PBCH block.

[0092] 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, if transmission times and resources overlap with other signals, it is preferable to transmit SSB preferentially. For this purpose, the network can broadcast or instruct SSB transmission time and resource information via UE-specific RRC signaling.

[0093] NR allows for beam-based transmit and receive operations. If the receiving performance of the current serving beam deteriorates, a process called beam failure recovery (BFR) can be initiated to search for a new beam.

[0094] Since BFR is not a process that declares an error / failure on the link between the network and the terminal, it can be assumed that the connection with the serving cell is currently maintained even when the BFR process is performed. During the BFR process, measurements are performed on different beams configured by the network (beams can be represented by CSI-RS ports or SSB (synchronization signal block) indices, etc.), and the terminal can select the best beam. The terminal can then proceed with the BFR process in a way that performs the RACH process associated with the beam that yielded the best measurement results.

[0095] The following describes the Transmission Configuration Indicator (TCI) state. The TCI state can be set for each core set of the control channel, and the parameters for determining the terminal's receive (Rx) beam can be determined based on the TCI state.

[0096] For each downlink bandwidth portion (DL BWP) of a serving cell, a terminal can be configured with up to three core sets. Furthermore, for each core set, the terminal can receive the following information:

[0097] 1) Core set index p (for example, one of 0 to 11, the BWP of a single serving cell can uniquely determine the index of each core set),

[0098] 2) PDCCH DM-RS scrambling sequence initialization value,

[0099] 3) Intervals in the time domain of the core set (which can be given in units of symbols),

[0100] 4) Resource block set,

[0101] 5) CCE-to-REG mapping parameters,

[0102] 6) Antenna port quasi co-location (QCL) information for DM-RS antenna ports for PDCCH reception, represented by the set of antenna port quasi co-locations (QCL) provided by the higher-level parameter "TCI-State" in each core set,

[0103] 7) Indications such as whether or not there is a transmission configuration indication (TCI) field for a specific DCI format transmitted by PDCCH in the core set.

[0104] Let's explain QCL. If the characteristics of the channel on which a symbol is transmitted on one antenna port can be inferred from the characteristics of the channel on which a symbol is transmitted on another antenna port, then the two antenna ports can be said to be in a quasi-common location (QCL). For example, if two signals (A and B) are transmitted from the same transmitting antenna array to which the same / similar spatial filters are applied, the two signals can go through the same / similar channel states. From the receiver's perspective, upon receiving one of the two signals, the other signal can be detected using the channel characteristics of the received signal.

[0105] In this sense, A and B being QCLed means that A and B undergo similar channel conditions, and therefore the channel information estimated to detect A is also useful when detecting B. Here, channel conditions can be defined by, for example, Doppler shift, Doppler spread, average delay, delay spread, spatial reception parameters, etc.

[0106] The "TCI-State" parameter associates one or two downlink reference signals with the corresponding QCL type (there are QCL types A, B, C, and D; see Table 4).

[0107] [Table 4]

[0108] Each "TCI-State" may include parameters for establishing a quasi-co-location (QCL) relationship between one or two downlink reference signals and the DM-RS ports of a PDSCH (or PDCCH), or the CSI-RS ports of a CSI-RS resource.

[0109] On the other hand, in each DL BWP configured on a terminal within a single serving cell, the terminal can receive up to 10 search space sets. For each search space set, the terminal can receive at least one of the following pieces of information:

[0110] 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 (per slot), 4) PDCCH monitoring pattern within a slot (e.g., indicating the first symbol of the core set within the slot for PDCCH monitoring), 5) Number of slots in which search space set s exists, 6) Number of PDCCH candidates by CCE aggregation level, 7) Information indicating whether search space set s is CSS or USS, etc.

[0111] In NR, core set #0 can be configured by PBCH (or terminal-specific signaling or PSCell configuration or BWP configuration for handover). 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 is necessary to minimize the search space occasions that the terminal needs to monitor. Alternatively, it is necessary to provide a beam sweeping control / data area that allows control / data transmission by each beam, enabling continuous communication with the terminal in situations where the terminal's best beam changes dynamically.

[0112] Figure 11 illustrates a physical channel and typical signal transmission.

[0113] Referring to Figure 11, in a wireless communication system, a terminal receives information from a base station via the downlink (DL) and 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 being transmitted and received.

[0114] When a terminal is turned on again after being turned off, or when a terminal newly enters a cell, it performs initial cell search operations, such as synchronizing with the base station (S11). For this purpose, the terminal receives 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). The terminal can also receive PBCH (Physical Broadcast Channel) from the base station to obtain broadcast information within the cell. Furthermore, the terminal can receive DL RS (Downlink Reference Signal) during the initial cell search step to check the downlink channel status.

[0115] (Initial) cell discovery can mean the procedure by which a terminal obtains time and frequency synchronization with a cell and detects the cell ID of said cell. Cell discovery can be performed based on the primary and secondary synchronization signals of said cell and the PBCH DMRS.

[0116] Once the terminal has completed the initial cell search, it can receive the PDCCH (Physical Downlink Control Channel) and its corresponding PDSCH (Physical Downlink Control Channel) to obtain more specific system information (S12).

[0117] Thereafter, the terminal can perform a random access procedure to complete the connection to the base station (S13-S16). Specifically, the terminal can transmit a preamble via PRACH (Physical Random Access Channel) (S13) and receive a Random Access Response (RAR) for the preamble via PDCCH and its corresponding PDSCH (S14). Thereafter, the terminal can transmit a PUSCH (Physical Uplink Shared Channel) using scheduling information in the RAR (S15) and perform a contention resolution procedure such as PDCCH and its corresponding PDSCH (this can be described as the process of receiving a contention resolution message) (S16).

[0118] A terminal that has performed the procedures described above can subsequently perform PDCCH / PDSCH reception (S17) and PUSCH / PUCCH (Physical Uplink Control Channel) transmission (S18) as general uplink / downlink signal transmission procedures. The control information that the terminal transmits to the base station is called 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 via PUCCH, but if control information and data should be transmitted simultaneously, it can be transmitted via PUSCH. In addition, at the request / instruction of the network, the terminal can transmit UCI aperiodically via PUSCH.

[0119] When bandwidth adaptation (BA) is configured, to enable reasonable battery consumption, only one uplink bandwidth part (BWP) and one downlink BWP, or one downlink / uplink BWP pair, for each uplink carrier can be activated at one time within the active serving cell, while all other BWPs configured on the terminal are deactivated. With deactivated BWPs, the terminal does not monitor PDCCH and does not transmit over PUCCH, PRACCH, and UL-SCH.

[0120] For the BA, the terminal's receive and transmit bandwidth does not need to be as wide as the cell bandwidth and can be adjusted: the width can be commanded to change (e.g., contract during periods of low activity to save power), the position 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 accommodate different services). A subset of the cell's overall bandwidth is called a bandwidth part (BWP), which the BA obtains by setting a BWP(s) for the terminal and informing the terminal which of the set BWPs is currently active. Once the BA is set, it is sufficient for the terminal to monitor the PDCCH on one active BWP; that is, it is not necessary to monitor the PDCCH on the cell's overall downlink frequency. A BWP deactivation timer (independent of the DRX deactivation timer mentioned above) is used when switching the active BWP to the default BWP: the timer is restarted if PDCCH decoding is successful, and switching to the default BWP occurs when the timer expires.

[0121] The following section describes the integrated access and backhaul link (IAB). For convenience of explanation, the proposed scheme is based on the new RAT (NR) system, but the scope of systems to which the proposed scheme applies can be extended to other systems outside of the NR system, such as the 3GPP (registered trademark; hereinafter the same) LTE / LTE-A system.

[0122] One potential technology that aims to enable future cellular network deployment scenarios and applications is one that allows for flexible and highly dense deployment of NR cells without the need to proportionally increase the density of the transport network as support for wireless backhaul and relay links.

[0123] With the expected availability of significantly larger bandwidths in NR compared to LTE, along with massive MIMO or native deployment of multi-beam systems (e.g., mmWave spectrum), opportunities arise for the development and deployment of integrated access and backhaul links. This allows for easier deployment of densely packed networks of self-backhauled NR cells in a more integrated manner by constructing a number of control and data channels / procedures defined to provide connectivity or access to terminals. Such systems are called integrated access and backhaul links (IABs).

[0124] This disclosure defines the following:

[0125] -AC(x): Access link between node(x) and terminal(ra).

[0126] -BH(xy): The backhaul link between node (x) and node (y).

[0127] At this time, the node can mean a DgNB (donor gNB) or a relay node (RN). Here, the DgNB or donor node is a gNB that provides a function to support the backhaul for the IAB node.

[0128] When there are relay node 1 and relay node 2, when relay node 1 is connected to relay node 2 by a backhaul link and relays the 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 named the child node of relay node 1.

[0129] In this specification, the technical features separately described in one drawing can be implemented separately or simultaneously.

[0130] The following drawings are created to illustrate a specific example of this specification. Since the names of specific devices and the names of specific signals / messages / fields described in the drawings are presented exemplarily, the technical features of this specification are not limited to the specific names used in the following drawings.

[0131] <PUSCH repetitions>

[0132] Type A and type B of PUSCH repetitions are introduced in the standard specifications (e.g., NR Rel-15 / 16). Depending on the PUSCH repetition type, transmission is performed as follows.

[0133] 1) PUSCH repetition type A

[0134] Figure 12 is an example of PUSCH repetition type A.

[0135] Referring to Figure 12, PUSCH repetition type A is a slot-based PUSCH repetition transmission, and as shown in Figure 12, the repetition is executed with the same PUSCH transmission start symbol position and PUSCH transmission symbol length for each slot. In this case, if there are invalid symbols among the symbol resources that make up a particular PUSCH repetition that cannot be used for PUSCH transmission, the corresponding PUSCH repetition transmission is dropped and not executed. For example, when a total of four PUSCH repetition transmissions, Rep0, Rep1, Rep2, and Rep3, are executed in slots N, N+1, N+2, and N+3 (one PUSCH repetition is transmitted in each slot), if the symbol resources that make up Rep1 contain invalid symbols, the transmission of Rep1 is dropped, and only the transmissions of Rep0, Rep2, and Rep3 are executed. Therefore, the actual number of repetitions executed is less than the set number of repetitions.

[0136] In the case of PUSCH repeat type A, frequency hopping can be set on the terminal using higher-level parameters. One of two frequency hopping modes can be set.

[0137] i) Frequency hopping within a slot is applicable to single-slot and multi-slot push transmissions.

[0138] ii) Frequency hopping between slots is applicable to multi-slot push transmission.

[0139] 2) PUSCH Repeat Type B

[0140] Figure 13 shows an example of the PUSCH repeating type B.

[0141] Referring to Figure 13, PUSCH repetition type B is executed in units of the symbol length in which the PUSCH is actually transmitted. For example, as shown in Figure 13(a), when a PUSCH is transmitted through 10 symbols, the PUSCH repetition is executed in units of 10 consecutive symbols. In this case, a repetition that determines the PUSCH repetition transmission time resource without considering slot boundaries, invalid symbols, etc., is called a nominal repetition. Figure 13(a) shows an example in which three nominal repetitions (shown as N0, N1, and N2) are set.

[0142] However, in the case of actual push repetitions, a single push cannot be transmitted while including a slot boundary. That is, if a nominal push transmission includes a slot boundary (for example, N0 and N2 in Figure 13(a)), two actual repetitions will be executed with the slot boundary as the boundary, as shown in Figure 13(b). For example, nominal repetition N0 will be executed as two actual repetitions, A0 and A1, with the slot boundary as the boundary.

[0143] Furthermore, a single PUSCH transmission can only be executed through a sequence of symbols. If there are invalid symbols in the time resource to which a PUSCH repetition should be transmitted, the actual repetition is constructed using a sequence of symbols with the invalid symbols as the boundary. For example, if symbols #0 to #9 constitute one nominal repetition and symbols #3 to #5 are invalid symbols, then symbols #0 to #2 and symbols #6 to #9, excluding the invalid symbols, will each constitute one actual repetition.

[0144] Invalid symbols may include the following symbols:

[0145] i) Downlink symbols set by semi-static TDD UL-DL settings,

[0146] ii) Invalid symbol patterns set by RRC (which can be set by an invalid symbol pattern indicator),

[0147] iii) SSB symbols set by SIB1, SSB symbols set by "ServngCellConfigCommon",

[0148] iv) Symbols for PDCCH for SIB1,

[0149] v) Invalid symbols for DL-UL switching configured by RRC.

[0150] If an actual repeat resource contains symbols that cannot be used for PUSCH transmissions (for example, DL symbols indicated by DCI format 2_0), that actual repeat transmission will be dropped and not executed.

[0151] The following explains full-duplex operation.

[0152] 5G is giving rise to new service types such as XR (Extended Reality), AI-based services, and self-driving cars. These services are characterized by dynamic traffic changes in both the downlink (DL) and uplink (UL) directions, and require low latency when traffic (e.g., packets) is transmitted. 5G services will see an explosive increase in traffic to support these diverse new use cases.

[0153] Conventional semi-static or dynamic TDD UL / DL configurations are limited by transmission time delay and operator interference issues. Conventional FDD methods have limitations in terms of efficient frequency resource utilization in the DL / UL direction. Therefore, the introduction of full-duplex operation within a single carrier is being discussed to achieve low delay times and efficient resource utilization in noise reduction (NR).

[0154] Figure 14 shows an example of a method that applies full duplex within the carrier wave.

[0155] Referring to Figure 14, the full-duplex scheme can consider subband-wise full duplex (hereinafter referred to as subband full duplex or SBFD) as shown in Figure 14(a) and spectrum-sharing full duplex (hereinafter referred to as SSFD) as shown in Figure 14(b).

[0156] In the case of SBFD, DL and UL transmission and reception are performed on different frequency resources within the same carrier wave (e.g., carrier wave #0). That is, DL and UL use different frequency resources for the same time resource.

[0157] In the case of SSFD, DL and UL transmission and reception are performed within the same carrier wave (e.g., carrier wave #0) via the same frequency resource or overlapping frequency resources. That is, the same or overlapping frequency resources can be used for DL ​​and UL for the same time resource.

[0158] Such full-duplex (FD) operation can also be used in combination with conventional half-duplex (HD) operation. For example, some of the time resources used for conventional half-duplex-based TDD operation can be used for full-duplex operation. The time resources used to perform full-duplex operation can, for example, perform SBFD or SSFD operation.

[0159] Figure 15 shows an example where time resources operating in HD (half duplex) and time resources operating in FD (full duplex), such as SBFD or SSFD, coexist.

[0160] In Figure 15(a), some time resources operating in SBFD are displayed in SBFD, and time resources operating in half-duplex are displayed in HD. In Figure 15(b), some time resources operating in SSFD are displayed in SSFD, and time resources operating in half-duplex are displayed in HD. The unit of time resources is, for example, slots or symbols.

[0161] In time resources operating under SBFD, some frequency resources are used as DL resources, and other frequency resources are used as UL resources. Between DL and UL frequency resources, there can be a guard subband that is not used as DL or UL. The guard subband can also be referred to by other terms such as guard frequency resources or guard subcarriers.

[0162] In time resources operating with SSFD, the entire frequency resource may be used for both DL and UL. Alternatively, to reduce the effects of interference from other adjacent carriers (referred to as ACI (adjacent carrier interference)), some frequency resources on one or both edges of the carrier may not be used for DL ​​and / or UL. That is, one or both edges of the carrier can be used as a guard band (guard subband) that is not used for both DL and UL. Alternatively, to reduce ACI affecting UL reception, one or both edges of the carrier may be used only for DL ​​transmission.

[0163] In this disclosure, slot resources operating in half-duplex mode are referred to as HD slots, and slot resources operating in SBFD mode and SSFD mode are referred to as SBFD slots (SBFD slots) and SSFD slots (SSFD slots), respectively. Furthermore, SSFD slots and SSFD slots are collectively referred to as FD slots.

[0164] In this disclosure, within the time resources operating in FD mode, the frequency resources operating in DL mode can be conveniently referred to as the DL subband, and the frequency resources operating in UL mode can be referred to as the UL subband.

[0165] 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 within the same time resources.

[0166] 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 using the same or different frequency resources within the same time resources, while the terminals can perform only DL reception or UL transmission within a given time resource. In this case, the base station performs full-duplex operation by performing DL transmission and UL reception with different terminals at the same time.

[0167] This disclosure is written assuming that the base station performs / supports full-duplex operation and the terminal performs / supports half-duplex operation. However, this disclosure may also apply when both the base station and the terminal perform / support full-duplex operation.

[0168] Based on these discussions, this disclosure proposes a terminal push transmission method for cases where a single push transmission contains both SBFD and non-SBFD symbols during intra-carrier full duplex operation within a carrier.

[0169] Hereafter, "network" can be interpreted as gNB or CU / DU. Similarly, "terminal (UE)" can be interpreted as IAB node MT (mobile terminal, mobile termination) or NCR-MT (network-controlled repeater MT).

[0170] A. Characteristics of DL / UL time / frequency resources for SBFD and SSFD operation

[0171] A cell (base station) can perform both DL transmission and UL reception using the same time resources in an FD scheme such as SBFD or SSFD. For example, a base station can perform HD operation in the first time resource and FD operation in the second time resource (which is the remaining time resource after the first time resource is deducted).

[0172] In the first time resource performing HD operations, DL operations or UL operations are performed across the entire frequency resource that constitutes the system bandwidth. Within the first time resource performing HD operations, the network performs DL operations via the 1-1 time resource and UL operations via the 1-2 time resource. In this case, the 1-1 time resource and the 1-2 time resource do not overlap with each other.

[0173] In the second time resource performing the FD operation, the network performs the DL operation through all or part of the frequency resources (first frequency resources) that make up the cell's system bandwidth, and performs the UL operation through all or part of the frequency resources (second frequency resources).

[0174] Figure 16 shows examples of the first time resource, the second time resource, the first frequency resource, and the second frequency resource.

[0175] Referring to Figure 16(a), in the first time resource (indicated as A), the device operates in half-duplex mode. In the second time resource (indicated as B), the device can operate, for example, in SBFD mode. In the first time resource, the resource indicated as DL corresponds to the 1-1 time resource described above, and the resource indicated as UL corresponds to the 1-2 time resource described above.

[0176] Referring to Figure 16(b), in the second time resource, the frequency resource operating in DL corresponds to the first frequency resource mentioned above, and the frequency resource operating in UL corresponds to the second frequency resource mentioned above.

[0177] Figure 17 shows the first time resource, the second time resource, the first frequency resource, and other examples of the second frequency resource.

[0178] Referring to Figure 17(a), in the first time resource (indicated as A), the device operates in half-duplex mode. In the second time resource (indicated as B), it can operate, for example, in SSFD mode. In the first time resource, the resource indicated as DL corresponds to the 1-1 time resource described above, and the resource indicated as UL corresponds to the 1-2 time resource described above.

[0179] Referring to Figure 17(b), in the second time resource, the frequency resources operating in DL and DL+UL correspond to the first frequency resource mentioned above, and the frequency resources operating in DL+UL correspond to the second frequency resource mentioned above.

[0180] The first frequency resource and / or the second frequency resource may have all or some of the following characteristics:

[0181] 1) When performing SBFD operation, the first and second frequency resources do not overlap. This is to ensure that DL and UL operations are performed via different frequency resources. In this case, there may be frequency resources that do not fall under the first and second frequency resources, and such frequency resources are called guard subbands or guard frequency resources. Such guard frequency resources are necessary to reduce interference between DL transmission and UL reception. Guard frequency resources can be located between the first and second frequency resources.

[0182] 2) When SSFD operation is performed, the first frequency resource and the second frequency resource may overlap. In this case, there may be frequency resources that do not fall under the first or second frequency resources, and such frequency resources are called guard subbands or guard frequency resources. Such guard frequency resources are necessary to reduce interference between DL transmission on adjacent carriers and / or UL reception on adjacent carriers.

[0183] 3) When SBFD operation is performed, the second frequency resource can consist of continuous frequency resources, and the first frequency resource can consist of discontinuous frequency resources. In this case, the first frequency resource can consist of a discontinuous set of multiple (e.g., 2) frequencies, and each of these frequencies can consist of continuous frequency resources. This is to position the second frequency resource used for UL at the center of the frequency resources that make up the cell, thereby reducing interference from DL transmission on adjacent carriers to the UL resource. Conversely, the first frequency resource can consist of continuous frequency resources, and the second frequency resource can consist of discontinuous frequency resources. In this case, the second frequency resource can consist of a discontinuous set of multiple (e.g., 2) frequencies, and each of these frequencies can consist of continuous frequency resources. This is to position the second frequency resource used for DL ​​at the center of the frequency resources that make up the cell, thereby reducing interference from DL transmission on adjacent carriers to the UL resource.

[0184] 4) When SSFD operation is performed, the second frequency resource can be composed of a portion of the first frequency resource. In this case, the second frequency resource can be made smaller than the first frequency resource by about X PRBs (physical resource blocks) per edge of one or both sides of the carrier wave. This is to reduce interference between DL transmission on adjacent carrier waves and UL reception.

[0185] The network can determine / judge the aforementioned "first time resource" and "second time resource," as well as the "first frequency resource" and "second frequency resource," and provide all or part of the relevant information to the terminal.

[0186] The terminal can determine information about time resources operating in SBFD (and / or SSFD) mode (hereinafter referred to as SBFD symbols) for the cell's FD (SBFD and / or SSFD) operation. For this purpose, information about SBFD symbols can be set on the terminal from the network.

[0187] When a specific time resource is set to be a time resource that operates in SBFD mode (SBFD symbol), both DL and UL resources can exist within that time resource. In this case, if there are no UL signals for the base station to receive within that time resource, the base station can perform only DL transmissions. Within an SBFD resource, DL transmissions are performed only within the DL subband. Therefore, even if there are no UL signals to be transmitted in the UL subband, DL transmissions can be performed only within the DL subband.

[0188] In this case, even if a specific time resource is determined to be an SBFD symbol, if there are no UL transmissions received by the base station, it may be considered to perform DL transmissions not only in the DL subband but also outside the DL subband in order to improve DL throughput. In other words, it may be considered to perform DL transmissions across the entire bandwidth.

[0189] In other words, for resources identified as SBFD symbols, a fallback to TDD operation, which performs DL or UL operation across the entire bandwidth instead of SBFD operation via the DL / UL subband, can be considered.

[0190] For resources that are not identified as SBFD symbols, the terminal can perform TDD operation (half-duplex operation) like a conventional terminal. That is, it can perform only DL or UL operation using the entire frequency resource of the cell.

[0191] The terminal can receive SBFD symbol information from the network. This allows it to determine whether a specific symbol is an SBFD symbol or a non-SBFD symbol.

[0192] i) If the terminal determines that a particular symbol is a non-SBFD symbol, it may perform legacy operation with that symbol (or decides to perform legacy operation).

[0193] ii) If the terminal determines that a particular symbol is an SBFD symbol, it determines that the symbol is capable of performing SBFD operations from a cell perspective.

[0194] There are cases where the terminal does not receive configuration information for SBFD symbols from the network. In this case, i) the terminal can determine that all symbols are non-SBFD symbols. Therefore, the terminal can operate like a legacy TDD with all symbols.

[0195] Alternatively, ii) if the terminal does not receive configuration information for SBFD symbols from the network, the terminal may determine that all symbols are SBFD symbols.

[0196] If a terminal determines that a particular symbol is an SBFD symbol, then i) generally, the terminal may perform DL reception in the DL subband and UL transmission in the UL subband during the time resources in which the cell determines that it is operating in SBFD mode. ii) Additionally, during the time resources in which the cell determines that it is operating in SBFD mode, the base station may choose to perform only DL transmission or UL reception, or, if necessary, perform DL transmission or UL reception across the entire band (and be subject to DL or UL scheduling).

[0197] Terminals can receive information about SBFD symbols / non-SBFD symbols (referred to as SBFD symbol / non-SBFD symbol information) from the network via semi-static signaling. This allows terminals to determine whether a particular symbol is used as an SBFD symbol or a non-SBFD symbol.

[0198] Alternatively, the terminal can determine the position of symbols used as SBFD symbols and / or non-SBFD symbols. In this case, the terminal can determine that symbols that do not receive SBFD symbol / non-SBFD symbol information settings are non-SBFD symbols. Alternatively, the terminal can determine that symbols that do not receive SBFD symbol / non-SBFD symbol information settings are SBFD symbols.

[0199] Subsequently, terminals can receive instructions for SBFD / non-SBFD symbol information from the network via dynamic signaling. Such instructions can be given via terminal-specific (UE-specific) DCI, for example, through DL grants / UL grants. Alternatively, such instructions can be given via terminal-group specific (UE-group specific) DCI, such as DCI format 2_0.

[0200] The aforementioned SBFD symbol / non-SBFD symbol information can specifically mean the following:

[0201] i) Information on whether a particular symbol resource is used as an SBFD symbol or a non-SBFD symbol.

[0202] ii) Information on whether a resource configured to operate with SBFD symbols will be switched to non-SBFD symbols.

[0203] iii) Information regarding whether, for a given symbol, DL and / or UL transmissions operate using the entire frequency resource (wideband) within the symbol, or only within a subband.

[0204] Such dynamic instructions can only be provided or applied to symbols that are determined to operate semi-statically with SBFD symbols.

[0205] The device can determine whether to use the UL subband or DL ​​subband based on its network settings.

[0206] i) The terminal receives information about the UL subband and DL subband from the network, which allows it to determine the frequency resources that make up the UL subband and DL subband.

[0207] ii) Alternatively, the terminal may receive only information for the UL subband from the network, thereby enabling it to determine the frequency resources that constitute the UL subband. In this case, the remaining frequency resources within the system bandwidth (system BW), excluding those set / determined as the UL subband, can be determined to be the DL subband. Additionally, if the terminal receives information for the frequency resources that constitute the guard subband, the remaining frequency resources within the system bandwidth, excluding those set / determined as the UL subband and guard subband, can be determined to be the DL subband.

[0208] iii) Alternatively, the terminal may receive settings from the network only for information regarding the DL sub-band, and thereby can determine the frequency resources constituting the UL sub-band. In this case, within the frequency resources constituting the system bandwidth, the remaining frequency resources excluding the frequency resources set / determined for the DL sub-band can be determined as the UL sub-band. Additionally, when the terminal receives settings for the frequency resources constituting the guard sub-band, within the frequency resources constituting the system bandwidth, the remaining frequency resources excluding the frequency resources set / determined for the DL sub-band and the guard sub-band can be determined as the UL sub-band.

[0209] In the present disclosure, the time resource or SBFD symbol operating in SBFD may mean the aforementioned "second time resource". Also, in the present disclosure, the time resource operating in TDD, the time resource operating in HD, the TDD symbol, or the HD symbol may mean the aforementioned "first time resource".

[0210] The DL sub-band referred to in the present disclosure may mean the aforementioned "first frequency resource". Also, the UL sub-band referred to in the present disclosure may mean the aforementioned "second frequency resource".

[0211] <Transmission / Reception Resources of PUSCH / PDSCH Considering SBFD Operation>

[0212] When the terminal receives scheduling of PUSCH transmission (DG (dynamic grant)-PUSCH, CG (configured grant)-PUSCH, TBoMS (TB processing over multiple slots), etc.) via RRC configuration and / or DCI signaling from the network, it is possible that some or all of the frequency resources allocated for the transmission of the corresponding PUSCH are not included in the UL sub-band.

[0213] For example, the network expects the terminal to receive CG-PUSCH using non-SBFD symbols, and sets the reception frequency resource of CG-PUSCH for the terminal. However, the transmission symbol of a specific CG-PUSCH can also include SBFD symbols.

[0214] FIG. 18 illustrates the frequency resources allocated for PUSCH transmission.

[0215] Referring to FIG. 18, when the base station schedules PUSCH repetition or TBoMS transmission to the terminal via a plurality of slot resources, the transmission symbols of PUSCH and TBoMS via the corresponding plurality of slots can include SBFD symbols. For example, frequency resources (PRBs) for PUSCH transmission are allocated to slots n to n+3, slot n is composed of non-SBFD symbols, and slots n+1 to n+3 can be composed of SBFD symbols.

[0216] Thus, the symbol resource for the terminal to transmit a specific PUSCH can include SBFD symbols. In this case, among the frequency resources allocated for the terminal to transmit PUSCH, all or some of the frequency resources may not be included in the UL sub-band so as to be known from slots n+1 to n+3.

[0217] When the terminal executes a specific PUSCH transmission, if the symbol resource for transmitting PUSCH includes SBFD symbols, the terminal can execute PUSCH transmission using all or some of the frequency resources within the UL sub-band among the frequency resources allocated for PUSCH transmission.

[0218] More specifically, the PUSCH transmission frequency resources can be determined as follows, and PUSCH transmission can be executed using the corresponding frequency resources.

[0219] i) Of the PRB resources that have been assigned to transmit PUSCH, only those PRB resources included in the UL subband can be identified as PRB resources that transmit PUSCH.

[0220] ii) Among the RGB resources that have been assigned to transmit PUSCH, only those RGB resources in which all PRBs constituting the RGB are included in the UL subband can be determined to be RGB resources that transmit PUSCH.

[0221] In this context, an SBFD symbol can refer to a symbol that a terminal determines, based solely on semi-static signaling from the network, indicates that the cell is operating under SBFD, while a non-SBFD symbol can refer to a symbol that a terminal determines, based solely on semi-static signaling from the network, indicates that the cell is operating under non-SBFD.

[0222] Alternatively, an SBFD symbol may mean a symbol that a terminal has determined to operate in SBFD mode based on semi-static and dynamic signaling from the network, or a symbol in which DL / UL operation is determined to be performed via resources within a subband. A non-SBFD symbol may mean a symbol that a terminal has determined to operate in non-SBFD mode based on semi-static and dynamic signaling from the network, or a symbol in which DL / UL operation is determined to be performed via the wideband (i.e., the entire frequency resource within the symbol).

[0223] Thus, when a terminal performs a push transmission using all or part of the frequency resources within the UL subband that have been allocated for push transmission, the actual push transmission may be performed using fewer PRB resources than those allocated for push transmission.

[0224] On the other hand, the transport block (TB) size (TBS) for PUSCH transmission can be determined based on the number of PRBs allocated (for example, via the FDRA field of the UL grant indicated via DCI).

[0225] i) PUSCH scheduled by a random access response (RAR) UL grant, ii) PUSCH scheduled by a fallback RAR UL grant, iii) PUSCH scheduled by DCI format 0_0 with scrambled CRC via C-RNTI, MCS-C-RNTI, TC-RNTI, CS-RNTI, iv) PUSCH scheduled by DCI format 0_1 ​​or DCI format 0_2 with scrambled CRC via C-RNTI, MCS-C-RNTI, CS-RNTI, v) In the case of CG-PUSCH or message A PUSCH transmission, MCS is between 0 and 27 (0≦I MCS If the value is ≤27) and transform precoding is activated, the terminal first determines the TBS by looking at the number of resource elements (RE) in the slot (N) as follows: RE Determine the total number of REs assigned to PUSCH.

[0226] For this purpose, the terminal first determines the number of REs (N') assigned to PUSCH within a single PRB. RE The following will be determined.

[0227]

number

[0228] In formula 1, N RB sc= 12, which is the number of subcarriers in the frequency domain of the physical resource block (PRB).

[0229] N sh symb This is the number of symbols L of the PUSCH allocation.

[0230] N PRB DMRS This is the number of REs for DM-RS per PRB in the allocated duration, including the overhead of the DM-RS CDM groups without data.

[0231] N PRB oh This is the overhead set by the higher-level parameter xOverhead in PUSCH-ServingCellConfig. PRB oh If not defined, N PRB oh It is treated as 0.

[0232] The terminal has the total number of REs (N) assigned to PUSCH as shown below. RE ) will be decided.

[0233] In the case of T BoMS, N RE =N*min(156, N' RE )·n PRB , here, n PRB is the total number of PRBs assigned to the terminal, and N is the number of slots used for TBS determination as indicated by "numberOfSlotsTBoMS". Otherwise, N RE =min(156, N'RE )·n PRB is as follows.

[0234] For example, the terminal obtains an unquantized intermediate variable (Unquantized intermediate variable, N RE , modulation and coding scheme field: I MCS ) based on the modulation order (modulation order, Q m ), target code rate (target code rate, R), number of layers (the number of layers, v), etc. determined based on the modulation and coding scheme field, and determines the quantized intermediate number of information bits (quantized intermediate number of information bits, N’ info ) according to the value of the N info . After that, the TBS can be determined based on this. info

[0235] For example, N info is obtained by the following formula.

[0236]

Equation

[0237] If N info is less than or equal to a specific value (for example, 3824), the quantized intermediate number N’ info of the information bits can be obtained as follows.

[0238] ]>

Equation

[0239] After that, in the following table, the closest TBS that is not less than N’ info and not smaller than N’info ) search.

[0240] [Table 5]

[0241] N info If it is greater than a specific value (e.g., 3824), then the quantized intermediate number N' of the information bits. info This can be calculated using the following formula.

[0242]

number

[0243] At this time, the target code rate R and N' info The TBS can be determined based on the value of , as shown in Table 6 below.

[0244] [Table 6]

[0245] Figure 19 illustrates the bits transmitted in each PUSCH during repeated PUSCH transmission.

[0246] Referring to Figure 19, the "transmitted bits" (also called rate-matched bits) are determined from the encoded bits (encoded bits) applied to each PUSCH transmission by the RV (Redundancy version) value.

[0247] For example, as shown in Figure 19, the encoded bits, consisting of systematic bits and parity bits, can be partially transmitted as follows: part 191 via a first push to which RV0 is applied; part 192 via a second push to which RV1 is applied; part 193 via a third push to which RV2 is applied; and part 194 via a fourth push to which RV3 is applied.

[0248] At this time, the amount of "bits transmitted" for each PUSCH is determined by the number of PRBs used for each PUSCH transmission.

[0249] Since the TB size is determined based on the number of PRBs allocated, as in the existing system, if the symbol resources sending a PUSCH include SBFD symbols, the actual PUSCH transmission may be performed using fewer PRB resources than those allocated for the PUSCH transmission. In this case, fewer "bits sent" (rate-matched bits) are transmitted via the PUSCH compared to when sending a PUSCH using non-SBFD symbols.

[0250] Therefore, even if PUSCH is transmitted to correspond to various RV values ​​through repeated and retransmitted PUSCH, encoded bits that cannot be transmitted may occur.

[0251] If some of the rate-matched bits corresponding to RV0 cannot be transmitted, these bits are called systematic bits, and this can have a greater impact on the receiving performance of PUSCH.

[0252] To solve these problems, the method for determining the TB size needs to be improved, taking into account the reduction in the number of transmitted PRBs in the SBFD slot.

[0253] With this in mind, this disclosure describes a method for determining the transport block size (TBS) of PUSCH / PDSCH transmitted and received by a terminal, taking into account SBFD symbols, during intra-carrier full duplex operation within a carrier wave.

[0254] Similar to the PUSCH example, when a terminal performs reception of a particular PDSCH, if the symbolic resource transmitting the PDSCH contains SBFD symbols, it may use all or part of the frequency resources within the DL subband of the frequency resources allocated for PDSCH reception to perform the PDSCH reception.

[0255] This disclosure describes a SBFD operation in which a cell performs DL and UL simultaneously using different frequency resources (sub-bands) within the same time resource. However, the contents of this disclosure can also apply when the cell performs an SSFD operation.

[0256] The contents of this disclosure are written assuming transmission of PUSCH (including TBoMS), but the contents of this disclosure can also be applied to reception of PDSCH. In this case, PUSCH and the UL subband can be interpreted as being substituted for the PDSCH and DL subbands, respectively.

[0257] As mentioned above, in order to determine the size of TB to be transmitted via PUSCH, the terminal is N as follows: RE Determine the value.

[0258] In the case of T BoMS, N RE =N*min(156, N' RE )·n PRB , here, n PRB is the total number of PRBs assigned to the terminal, and N is the number of slots used for TBS determination, as indicated by "numberOfSlotsTBoMS".

[0259] In other cases, N RE=min(156, N' RE )·n PRB That is the case.

[0260] At this time, n PRB This is the same as the number of PRBs that the terminal has assigned to the FDRA field for PUSCH transmission.

[0261] On the other hand, if the time resources used by a terminal to transmit a PUSCH include an SBFD symbol, the terminal can transmit the PUSCH using only PRB resources within the UL subband. In this case, the terminal can perform the PUSCH transmission using fewer PRB resources than the number of PRBs it has been allocated.

[0262] Alternatively, the number of PRBs used (or allocated) for a PUSCH transmission using a non-SBFD symbol may differ from the number of PRBs used (or allocated) for a PUSCH transmission using a symbol that includes an SBFD symbol. In other words, the number of PRBs used for a PUSCH transmission can vary depending on the symbol type of the symbol being transmitted (SBFD symbol or non-SBFD symbol).

[0263] For example, the number of PRBs assigned to a terminal is n PRB In this case, when a terminal sends a PUSCH using an SBFD resource, the number of PRBs that the terminal actually uses to send the PUSCH is n' PRB n is the number of PRBs used (or assigned) for PUSCH transmissions using non-SBFD symbols. PRB In this case, the number of PRBs used (or allocated) for PUSCH transmissions using symbols including SBFD symbols is n'. PRB This can be done. In this case, n' PRB is, n PRB Same as, or n PRB Smaller.

[0264] At this time, nPRB The values ​​are specifically as follows:

[0265] i) The number of PRBs allocated for PUSCH transmission.

[0266] ii) The number of PRBs assigned to apply to PUSCH sent using Non-SBFD symbols.

[0267] iii) The number of PRBs that the terminal uses for PUSCH transmission in Non-SBFD symbols.

[0268] At this time, n' PRB The values ​​are specifically as follows:

[0269] i) The number of PRBs allocated for PUSCH transmission that are included in the UL subband.

[0270] ii) The number of PRBs constituting A RBs among the RBs allocated for PUSCH transmission, where all PRBs constituting the RBs are included in the UL subband.

[0271] iii) The number of PRBs that the terminal uses for PUSCH transmission in the SBFD symbol.

[0272] 5.1. Method for determining the TB size (TBS) of a PUSCH transmission

[0273] The following is the N that the terminal uses to determine the TB size of the PUSCH transmission. RE The method for calculating the value of N will be explained. For the specific process of determining TBS, you can refer to, for example, the aforementioned formulas 1 to 1-3, Table 5, and Table 6, at which point N RE The value of can be determined by at least one of the following methods.

[0274] Method 1. The terminal can determine the TB size of the PUSCH based on the number of PRBs used for PUSCH transmission in the SBFD symbol.

[0275] The terminal determines the TB size of the PUSCH transmission, N RE The value can be determined as follows.

[0276]

number

[0277] In the above equation 2, the value of α (scaling factor) is a positive number equal to or less than 1. More specifically, the value of α can be determined as follows.

[0278] Alt a.α is the same as the ratio of the number of PRBs allocated for push transmission to the number of PRBs actually used for push transmission in SBFD symbols. Or, α is the same as the ratio of the number of PRBs used for push transmission in non-SBFD symbols to the number of PRBs used for push transmission in SBFD symbols. That is, α is n' PRB / n PRB It is the same as this.

[0279] Alt b.α is a value that the terminal receives from the network. Such values ​​can be set via RRC (radio resource control), MAC-CE (media access control-control element), DCI (downlink control information) signaling, etc.

[0280] Method 2. The terminal can determine the TB size of the PUSCH based on the average number of PRBs used for PUSCH transmission.

[0281] The terminal determines the TB size of the PUSCH transmission, N RE The value can be determined as follows.

[0282]

number

[0283] In equation 3, the value of α is a positive number equal to or less than 1. More specifically, the value of α can be determined as follows.

[0284] Alt a.α is the same as the ratio of the number of PRBs allocated for push transmission to the number of PRBs actually used for push transmission in SBFD symbols. Or, α is the same as the ratio of the number of PRBs used for push transmission in non-SBFD symbols to the number of PRBs used for push transmission in SBFD symbols. That is, α is n' PRB / n PRB It is the same as this.

[0285] Alt b.α is a value that the terminal receives from the network. Such values ​​can be set via RRC, MAC-CE, DCI signaling, etc.

[0286] In equation 3, the value of K can represent the number of repetitions applied to the PUSCH transmission.

[0287] In equation 3, the K2 value can be determined by one of the following methods.

[0288] i) This means the number of push transmissions out of K push transmissions in which at least one symbol in the push transmission is an SBFD symbol. Or, it means the number of push transmissions out of K push transmissions in which all symbols in the push transmission are SBFD symbols.

[0289] ii) The number of PRBs assigned to K PUSCH transmissions n PRB This refers to the number of push transmissions sent using fewer PRBs.

[0290] iii) Of the K PUSCH transmissions, n' PRB This refers to the number of PUSCH transmissions sent using PRBs.

[0291] iv) It is the same as K-K1.

[0292] In equation 3, the K1 value can be determined by one of the following methods.

[0293] i) This means the number of push transmissions out of K push transmissions in which at least one symbol constituting the push transmission is a non-SBFD symbol. Or, it means the number of push transmissions out of K push transmissions in which all symbols constituting the push transmission are non-SBFD symbols.

[0294] ii) The number of PRBs assigned to K PUSCH transmissions n PRB This refers to the number of PUSCH transmissions sent using all available resources.

[0295] iii) Of the K PUSCH transmissions, n PRB This refers to the number of PUSCH transmissions sent using PRBs.

[0296] iv) It is the same as K-K2.

[0297] The aforementioned equation 3 can also be transformed as shown in equation 3-1 below.

[0298]

number

[0299] In equation 3-1, (K1 / K + αK2 / K) can also be replaced with a single scaling factor β.

[0300] In that case, equation 3 below can be expressed as equation 3-2 below.

[0301]

number

[0302] In other words, equation 3 can be expressed in the same form as equation 2, as in equation 3-2, and in this case, the scaling factors β and α may have different physical meanings / values. For example, α is a scaling factor that shows how much smaller the number of frequency domain resources (PRBs) used for push transmission in SBFD resources is compared to the number of frequency domain resources used for push transmission in non-SBFD resources, such as the ratio of the number of PRBs used for push transmission in non-SBFD symbols (or HD slots) to the number of PRBs used for push transmission in SBFD symbols (or FD slots). In contrast, β is a scaling factor that reflects the average number of frequency domain resources (PRBs) used for push transmission when push transmission is performed in time resources including HD slots and FD slots.

[0303] Figure 20 illustrates how a terminal operates in a wireless communication system.

[0304] Referring to Figure 20, the terminal determines the size of the transport block (TB) (S201).

[0305] The terminal transmits the TB having the aforementioned size via a physical uplink shared channel (PUSCH) in each of the multiple slots, and the multiple slots include FD (full duplex) slots that can simultaneously perform uplink and downlink operations using different frequency bands within the slot, and HD (half duplex) slots that can perform uplink or downlink operations within the slot, and the size is determined based on the total number of resource elements allocated for PUSCH (N) of physical resource blocks (PRB) transmitted in the HD slot. RE It is determined based on the value obtained by applying the scaling factor to ) (S202).

[0306] The scaling factor is the ratio of the number of PRBs allocated for transmission on the physical uplink shared channel (PUSCH) to the number of PRBs used for transmission on the physical uplink shared channel by the FD symbols contained in the FD slot.

[0307] Specifically, the scaling factor is (number of PRBs used for transmission of the physical uplink shared channel in the FD slots) / (number of PRBs allocated for transmission of the physical uplink shared channel (PUSCH)).

[0308] In the embodiment, the scaling factor is the ratio of the number of PRBs allocated for transmission on the physical uplink shared channel using HD symbols contained in the HD slot to the number of PRBs used for transmission on the physical uplink shared channel using FD symbols contained in the FD slot.

[0309] Specifically, the scaling factor is (number of PRBs used for transmitting physical uplink shared channels with FD symbols contained in FD slots) / (number of PRBs allocated for transmitting physical uplink shared channels with HD symbols contained in HD slots).

[0310] In the embodiment, the scaling factor is a value set from the network and can be set via at least one of the following: RRC (radio resource control) messages, MAC-CE (media access control-control element), or DCI (downlink control information).

[0311] The specific method for determining the scaling factor is as described in Method 1 above.

[0312] In the embodiment, the scaling factor is determined based on the average number of PRBs used for transmission of the physical uplink shared channel in the multiple slots. The specific method for determining the scaling factor in this way has been described in Method 2 above.

[0313] Figure 21 illustrates the signaling process and operation between the base station and the terminal when the method in Figure 20 is applied.

[0314] Referring to Figure 21, the base station provides the terminal with scheduling information to schedule uplink transmissions (S211).

[0315] The base station receives transport blocks (TB) having a specific transport block size (TBS) via PUSCH in each of the multiple slots (S212).

[0316] Specifically, the base station receives a transport block (TB) having a specific transport block size (TBS) from the terminal based on the scheduling information via a physical uplink shared channel (PUSCH) in each of the multiple slots, and the multiple slots include FD (full duplex) slots that can simultaneously perform uplink and downlink operations using different frequency bands within the slot, and HD (half duplex) slots that can perform uplink or downlink operations within the slot, and the TBS is determined based on the total number of resource elements allocated for PUSCH (N) which is determined based on the physical resource block (PRB) transmitted in the HD slot. RE It is determined based on the value obtained by applying the scaling factor to ).

[0317] According to the method of this disclosure, when a PUSCH repetition transmission is transmitted across slots of different types in the time domain, for example, a mix of FD slots and HD slots, the TBS can be determined to reflect the frequency domain resources actually used in each slot, thereby reducing the probability of errors.

[0318] Furthermore, if the PUSCH repeat transmissions are transmitted across different types of slots in the time domain, this prevents ambiguity in how the TBS (Time-Based Sentence) is determined.

[0319] In addition, as shown in Figures 20 and 21, the above-described method for determining TB size can be applied in the following conditions / situations.

[0320] Condition 1. In an SBFD cell, the terminal always applies the TB size determination method described above.

[0321] When the cell performs the SBFD operation, the terminal always applies such a method. That is, even if the actual PUSCH is transmitted using only non-SBFD symbols, when the cell performs the SBFD operation, the terminal applies the method to determine the N RE value. At this time, for example, when the terminal receives from the network the setting of the symbol resource that operates in SBFD or the information on the symbol resource that can operate in SBFD for a specific cell, the terminal can determine that the corresponding cell performs the SBFD operation. And / or when the terminal receives from the network the setting of the UL sub-band (and / or DL sub-band) information for a specific cell, the terminal can determine that the corresponding cell performs the SBFD operation.

[0322] Condition 2. When the symbol constituting the first PUSCH transmission includes an SBFD symbol, apply the TB size determination method.

[0323] When the PUSCH is transmitted K times (including K = 1), among the K PUSCH transmissions, if the symbol constituting the first PUSCH transmission includes at least one SBFD symbol, the terminal applies the method (that is, the method according to the present disclosure) to determine the N RE value for PUSCH transmission. Otherwise, the terminal applies the legacy method (that is, the conventional method) to determine the N RE value.

[0324] Or, when the PUSCH is transmitted K times (including K = 1), if the symbols constituting the first PUSCH transmission are all composed of SBFD symbols, the terminal applies the method according to the present disclosure to determine the N RE value for PUSCH transmission. Otherwise, the terminal applies the legacy method to determine the N RE value.

[0325] Or, when the PUSCH is transmitted K times (including K = 1), if the first PUSCH transmission is n' PRB (<n PRBWhen transmitted using [[ID=]], the terminal applies the method according to the present disclosure to determine the N for PUSCH transmission. RE Otherwise, the terminal applies the legacy method to determine the N RE value.

[0326] In the case of PUSCH repetition type B, the first PUSCH transmission can mean the first nominal repetition.

[0327] Condition 3. When the SBFD symbol is included in the symbols constituting K PUSCH repeated transmissions, the TB size determination method according to the present disclosure is applied.

[0328] When the PUSCH is transmitted K times (including K = 1), for at least one PUSCH transmission among the K PUSCH transmissions, if the symbols constituting the PUSCH transmission include at least one SBFD symbol, the terminal applies the method according to the present disclosure to determine the N for PUSCH transmission. RE Otherwise, the terminal applies the legacy method to determine the N RE value.

[0329] When the PUSCH is transmitted K times (including K = 1), for at least one PUSCH transmission among the K PUSCH transmissions, if all the symbols constituting the PUSCH transmission are composed of SBFD symbols, the terminal applies the method according to the present disclosure to determine the N for PUSCH transmission. RE Otherwise, the terminal applies the legacy method to determine the N RE value.

[0330] Or, when the PUSCH is transmitted K times (including K = 1), for at least one PUSCH transmission among the K PUSCH transmissions, if the PUSCH transmission uses n’ PRB (<n PRB ) PRBs for transmission, the terminal applies the method according to the present disclosure to determine the N for PUSCH transmission. REDetermine the value. Otherwise, the terminal applies the legacy method to N RE Determine the value.

[0331] Condition 4. Apply the TB size determination method described herein as instructed by the network.

[0332] If a terminal receives an instruction from the network via explicit signaling to reduce / adjust the TB size, the terminal shall apply the method described herein to send N for PUSCH transmission. RE Determine the value. Otherwise, the terminal applies the legacy method to N RE Determine the value. The signaling can be indicated via RRC and / or DCI signaling.

[0333] When the signaling is instructed via an RRC message (information element), and the terminal receives an instruction to reduce / adjust the TB size via the instruction, the terminal can always apply the method of this disclosure. Alternatively, upon receiving such an instruction, the terminal can apply the method of this disclosure if conditions 1, 2, or 3 are additionally met.

[0334] If the signaling is directed via DCI, and the terminal receives an instruction to reduce / adjust the TB size via the instruction, the terminal may apply the method of the Disclosure to the PUSCH scheduled via the DCI that received the instruction. Alternatively, if the PUSCH scheduled via such DCI that has received such an instruction additionally satisfies conditions 1, 2, or 3, the method of the Disclosure may be applied to the PUSCH in question.

[0335] Condition 5. When the terminal receives a value of α from the network, the TB size determination method described in this disclosure shall be applied.

[0336] When a terminal receives a setting of the value of α from the network, the terminal applies the method according to this disclosure to N for PUSCH transmission. REDetermine the value. Otherwise, the terminal applies the legacy method to N RE Determine the value. Alternatively, upon receiving such instructions, the method according to this disclosure may be applied if the conditions 1, 2, or 3 described above are additionally met.

[0337] Condition 6. The method for determining the TB size according to this disclosure is applied depending on the type of symbol to which PUSCH is sent (i.e., whether it is an SBFD symbol or a non-SBFD symbol).

[0338] A terminal can receive instructions via DCI, which schedules PUSCH transmissions from the network, regarding the symbol type (SBFD symbol / non-SBFD symbol) of the symbol resource that will execute the PUSCH transmission. That is, it can receive instructions on whether to execute the PUSCH transmission assuming an SBFD symbol or a non-SBFD symbol. If the terminal is instructed to execute the PUSCH transmission assuming an SBFD symbol, the terminal can apply the method described herein to perform the N for PUSCH transmission. RE Determine the value. Otherwise, the terminal applies the legacy method to N RE Determine the value.

[0339] In this context, the SBFD / non-SBFD symbols have the following meanings:

[0340] i) An SBFD symbol can mean a symbol that a terminal determines to be operating in SBFD mode based on semi-static signaling received from the network. A non-SBFD symbol can mean a symbol that a terminal determines to be operating in non-SBFD mode based on semi-static signaling received from the network. Characteristically, these assumptions can be applied to conditions 1 to 5 above.

[0341] ii) Alternatively, an SBFD symbol may mean a symbol that the terminal determines to operate in SBFD mode based on semi-static and dynamic signaling received from the network, or a symbol that the terminal determines will perform UL operation via resources within the UL subband. A non-SBFD symbol may mean a symbol that the terminal determines to operate in non-SBFD mode based on semi-static and dynamic signaling received from the network, or a symbol that the terminal determines will perform UL operation not only on resources within the UL subband but also on resources outside the UL subband.

[0342] The methods described above can also be applied only to PUSCH transmissions that do not use TBoMS (TB processing over multiple slots).

[0343] 5.2. Method for determining the TB size for TBoMS transmission.

[0344] The terminal determines the TB size for TBoMS transmission as follows: N RE The value of can be calculated.

[0345] Method 1. The terminal can determine the TB size (TBS) for TBoMS based on the number of PRBs used for TBoMS transmission in the SBFD symbol.

[0346] The terminal determines the TB size of the TBoMS transmission, N RE The value can be determined using the following formula.

A non-SBFD symbol can mean a symbol that a terminal determines to be operating in non-SBFD mode based on semi-static signaling received from the network. Characteristically, these assumptions can be applied to conditions 1 to 5 above.

[0411] ii) Alternatively, an SBFD symbol may mean a symbol that the terminal determines to operate in SBFD mode based on semi-static and dynamic signaling received from the network, or a symbol that the terminal determines will perform UL operation via resources within the UL subband.

[0423] Figure 23 shows an example of a signal processing module structure. Here, signal processing can also be performed by processors 102 and 202 in Figure 23.

[0424] Referring to Figure 23, a transmitting device within a terminal or base station (e.g., a processor, a processor and memory, or a processor and transceiver) 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.

[0425] The transmitting device can transmit one or more codewords. Each coded bit within each codeword is scrambled by the scrambler 301 and transmitted over the physical channel. A codeword is also called a data sequence and is equivalent to a transport block, which is a data block provided by the MAC hierarchy.

[0426] The scrambled bits are modulated into complex-valued modulation symbols by modulator 302. Modulator 302 can modulate the scrambled bits according to the modulation scheme and place them in complex-valued modulation symbols that represent positions on a signal constellation. There are no restrictions on the modulation scheme, and m-PSK (m-Phase Shift Keying) or m-QAM (m-Quadrature Amplitude Modulation), among others, can be used to modulate the encoded data. The modulator is also called a modulation mapper.

[0427] The complex modulation symbols can be mapped on one or more transmission layers by the layer mapper 303. The complex modulation symbols on each layer can be mapped on the antenna port mapper 304 for transmission on the antenna port.

[0428] The resource block mapper 305 can map complex modulation symbols for each antenna port to the appropriate resource element within a virtual resource block allocated for transmission. The resource block mapper can map the virtual resource block to a physical resource block using an appropriate mapping scheme. The resource block mapper 305 can assign the complex modulation symbols for each antenna port to the appropriate subcarrier, which can then be multiplexed by the user.

[0429] The signal generator 306 can modulate complex modulation symbols for each antenna port, i.e., antenna-specific symbols, using a specific modulation scheme, such as OFDM (Orthogonal Frequency Division Multiplexing), to generate complex-valued time domain OFDM symbol signals. The signal generator can perform an IFFT (Inverse Fast Fourier Transform) on the antenna-specific symbols, and a CP (Cyclic Prefix) can be inserted into the time domain symbols after the IFFT has been performed. The OFDM symbols are transmitted to the receiving device via each transmitting antenna after undergoing digital-to-analog conversion, frequency uplink conversion, etc. The signal generator may include an IFFT module, a CP inserter, a DAC (Digital-to-Analog Converter), a frequency uplink converter, etc.

[0430] Figure 24 shows another example of a signal processing module structure within a transmitting device. Here, signal processing can be performed by the terminal / base station processors, such as processors 102, 202, etc., in Figure 22.

[0431] Referring to Figure 45, the transmitting equipment within a terminal or base station (e.g., a processor, a processor and memory, or a processor and transceiver) 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.

[0432] The transmitting device can transmit a codeword via a physical channel after scrambling the coded bits within the codeword using the scrambler 401.

[0433] The scrambled bits are modulated into complex modulation symbols by modulator 402. The modulator can modulate the scrambled bits using a predetermined modulation scheme to place them into complex modulation symbols that represent positions on a signal constellation. There are no restrictions 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.

[0434] The complex modulation symbols can be mapped to one or more transmission layers by the layer mapper 403.

[0435] The complex modulation symbols on each layer can be precoded by the precoder 404 for transmission on the antenna port. Here, the precoder can perform transform precoding on the complex modulation symbols before performing precoding. Alternatively, the precoder can perform precoding without performing transform precoding. The precoder 404 processes the complex modulation symbols in a MIMO manner using multiplexed transmitting antennas to output antenna-specific symbols, and can distribute these 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 NXM, where N is the number of antenna ports and M is the number of layers.

[0436] The resource block mapper 405 maps the demodulated modulation symbols for each antenna port to the appropriate resource elements within the virtual resource block allocated for transmission.

[0437] The resource block mapper 405 assigns complex modulation symbols to appropriate subcarriers, which can then be multiplexed by the user.

[0438] The signal generator 406 can generate complex-valued-time-domain OFDM (Orthogonal Frequency Division Multiplexing) symbol signals by modulating complex modulation symbols to a specific modulation scheme, such as OFDM. The signal generator 406 can perform an IFFT (Inverse Fast Fourier Transform) on antenna-specific symbols, and a CP (Cyclic Prefix) can be inserted into the time-domain symbols after the IFFT has been performed. The OFDM symbols are transmitted to the receiving device via each transmitting antenna after undergoing digital-to-analog conversion, frequency uplink conversion, etc. The signal generator 406 may include an IFFT module, a CP inserter, a DAC (Digital-to-Analog Converter), a frequency uplink converter, etc.

[0439] The signal processing process of the receiving device can be configured in reverse of the signal processing process of the transmitter. Specifically, the processor of the receiving device performs decoding and demodulation of radio signals received externally via the antenna ports of the transceiver. The receiving device may include multiple receiving antennas, and each signal received via the receiving antennas is restored to a baseband signal, then multiplexed and MIMO demodulated to be restored to the data sequence that the transmitter originally intended to transmit. 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 processed received signals, and a channel demodulator for demodulating the multiplexed signal sequence to the corresponding codeword. The signal restorer, multiplexer, and channel demodulator may be configured as a single integrated module performing these functions or as separate independent modules. More specifically, the signal restorer may include an ADC (analog-to-digital converter) that converts an analog signal to a digital signal, a CP remover that removes CP from the digital signal, an FFT module that applies an FFT (fast Fourier transform) to the signal from which 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 the transmission layer by a multiplexer, and the transmission layer is restored to the codeword that the transmitting device intended to transmit by a channel demodulator.

[0440] Figure 25 shows an example of a wireless communication device relating to an embodiment of the present disclosure.

[0441] Referring to Figure 25, a wireless communication device, such as a terminal, may include at least one of the following: a processor 2310 such as a digital signal processor (DSP) or microprocessor, a transceiver 2335, a power management module 2305, an antenna 2340, a battery 2355, a display 2315, a keypad 2320, a GPS (Global Positioning System) chip 2360, a sensor 2365, a memory 2330, a SIM (Subscriber Identification Module) card 2325, a speaker 2345, and a microphone 2350. There may be multiple antennas and processors.

[0442] Processor 2310 can embody the functions, procedures, and methods described herein. Processor 2310 in Figure 25 is the same as processors 102 and 202 in Figure 22.

[0443] Memory 2330 is connected to processor 2310 and stores information related to the operation of the processor. Memory can be located inside or outside the processor and can be connected to the processor via various technologies such as wired or wireless connections. Memory 2330 in Figure 25 is the same as memories 104 and 204 in Figure 22.

[0444] The user can input various types of information, such as phone numbers, using various techniques, such as pressing buttons on the keypad 2320 or activating voice using the microphone 2350. The processor 2310 receives and processes the user's information and can perform appropriate functions, such as making a call to the entered phone number. In some scenarios, data can be retrieved from the SIM card 2325 or memory 2330 to perform appropriate functions. In some scenarios, the processor 2310 can display various types of information and data on the display 2315 for the user's convenience.

[0445] The transceiver 2335 is connected to the processor 2310 and transmits and / or receives radio signals such as RF (Radio Frequency) signals. The processor can control the transceiver to initiate communication or transmit radio signals containing various types of information or data, such as voice communication data. The transceiver includes a transmitter and a receiver for transmitting and receiving radio signals. The antenna 2340 facilitates the transmission and reception of radio signals. In some embodiments, upon receiving a radio signal, the transceiver can forward and convert the signal to a baseband frequency for processing by the processor. The processed signal can be processed by various techniques, such as being converted into audible or readable information to be output via the speaker 2345. The transceiver in Figure 25 is the transceiver 106, 206 in Figure 29.

[0446] Although not shown in Figure 25, various other components, such as a camera and a USB (Universal Serial Bus) port, can be additionally included in the terminal. For example, the camera can be connected to the processor 2310.

[0447] Figure 25 is merely one example of a terminal, and is not limited to this example. A terminal does not necessarily have to include all the elements in Figure 25. That is, some components, such as the keypad 2320, GPS (Global Positioning System) chip 2360, sensor 2365, and SIM card 2325, may not be essential and may not be included in the terminal.

[0448] Figure 26 illustrates another example of a wireless device.

[0449] According to Figure 26, the wireless device may include at least one processor 102, 202, at least one memory 104, 204, at least one transceiver 106, 206, and one or more antennas 108, 208.

[0450] The difference between the wireless device example described in Figure 22 and the wireless device example in Figure 26 is that in Figure 22, the processors 102 and 202 and the memory 104 and 204 are separate, while in the example in Figure 26, the memory 104 and 204 are included in the processors 102 and 202. In other words, the processor and memory can also constitute a single chipset.

[0451] Figure 27 illustrates a communication system 1 to which this specification applies.

[0452] Referring to Figure 27, the communication system 1 to which this specification applies includes wireless equipment, base stations, and networks. Here, wireless equipment means equipment that performs communication using wireless connectivity technology (e.g., 5G NR (New RAT), LTE (Long Term Evolution)), and is also called communication / wireless / 5G equipment. Although not limited to these, wireless equipment may include robots 100a, vehicles 100b-1, 100b-2, XR (eXtended Reality) equipment 100c, handheld devices 100d, home appliances 100e, IoT (Internet of Things) equipment 100f, and AI equipment / servers 400. For example, vehicles may include vehicles equipped with wireless communication capabilities, autonomous vehicles, and vehicles capable of performing vehicle-to-vehicle communication. Here, vehicles may include UAVs (Unmanned Aerial Vehicles) (e.g., drones). XR devices include AR (Augmented Reality) / VR (Virtual Reality) / MR (Mixed Reality) devices and can be embodied in forms such as HMDs (Head-Mounted Devices), HUDs (Head-Up Displays) installed in vehicles, televisions, smartphones, computers, wearable devices, home appliances, digital signage, vehicles, and robots. Portable devices can include smartphones, smart pads, wearable devices (e.g., smartwatches, smart glasses), and computers (e.g., notebooks). Home appliances can include TVs, refrigerators, and washing machines. IoT devices can include sensors, smart meters, and so on. For example, base stations and networks can also be embodied in wireless devices, and specific wireless devices 200a can also operate as base stations / network nodes for other wireless devices.

[0453] Wireless devices 100a to 100f can be connected to network 300 via base station 200. Artificial Intelligence (AI) technology can be applied to wireless devices 100a to 100f, and wireless devices 100a to 100f can be connected to AI server 400 via network 300. Network 300 can be configured using a 3G network, 4G (e.g., LTE) network, or 5G (e.g., NR) network. Wireless devices 100a to 100f can communicate with each other via base station 200 / network 300, but they can also communicate directly without going through base station / network (e.g., sidelink communication). For example, vehicles 100b-1 and 100b-2 can communicate directly (e.g., V2V (Vehicle to Vehicle) / V2X (Vehicle to everything) communication). Furthermore, IoT devices (e.g., sensors) can communicate directly with other IoT devices (e.g., sensors) or other wireless devices 100a to 100f.

[0454] Wireless communication / connection 150a, 150b, and 150c can be performed between wireless devices 100a-100f / base station 200 and between base stations 200 / base station 200. Here, wireless communication / connection can be performed via uplink / downlink communication 150a and sidelink communication 150b (or D2D communication), and communication between base stations 150c (e.g., relay, IAB (Integrated Access Backhaul), or via various wireless connectivity technologies (e.g., 5G NR)). Through wireless communication / connection 150a, 150b, and 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, and 150c can transmit / receive signals via various physical channels. To this end, at least some of the following can be performed based on the various proposals herein: 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.), resource allocation processes, etc.

[0455] On the other hand, NR supports a number of numerologies (or subcarrier spacings (SCS)) to support a variety of 5G services. For example, an SCS of 15kHz supports wide area in the traditional cellular band; an SCS of 30kHz / 60kHz supports dense-urban, lower latency, and wider carrier bandwidth; and an SCS of 60kHz or higher supports bandwidths greater than 24.25GHz to overcome phase noise.

[0456] NR frequency bands can be defined as two types of frequency ranges (FR1 and FR2). The numerical values ​​of the frequency ranges can be changed; for example, the two types of frequency ranges (FR1 and FR2) are shown in Table 7 below. For convenience of explanation, among the frequency ranges used in NR systems, FR1 can mean the "sub 6GHz range," and FR2 can mean the "above 6GHz range," and these can be called millimeter waves (mmW).

[0457] [Table 7]

[0458] As mentioned above, the numerical values ​​of the frequency range of the NR system can be changed. For example, FR1 can include a bandwidth of 410 MHz to 7125 MHz, as shown in Table 8 below. That is, FR1 can include frequency bands of 6 GHz (or 5850, 5900, 5925 MHz, etc.) or higher. For example, frequency bands of 6 GHz (or 5850, 5900, 5925 MHz, etc.) or higher included within FR1 can include unlicensed bands. Unlicensed bands can be used for a variety of applications, for example, for vehicle communications (e.g., autonomous driving).
