[0036] In the following explanation, ‘when, if, in case of’ can be replaced with ‘based on’.

[0037] Technical features individually described in a single drawing in this specification may be implemented individually or simultaneously.

[0038] In this specification, higher layer parameters may be parameters that are set for the terminal, preset, or predefined. For example, a base station or network may transmit higher layer parameters to the terminal. For example, higher layer parameters may be transmitted via radio resource control (RRC) signaling or medium access control (MAC) signaling.

[0040] The technology proposed in this specification can be used in various wireless communication systems such as CDMA (code division multiple access), FDMA (frequency division multiple access), TDMA (time division multiple access), OFDMA (orthogonal frequency division multiple access), and SC-FDMA (single carrier frequency division multiple access). CDMA can be implemented with wireless technologies such as UTRA (universal terrestrial radio access) or CDMA2000.

[0041] The technology proposed in this specification can be implemented with 6G wireless technology and applied to various 6G systems. For example, 6G systems can have key factors such as enhanced mobile broadband (eMBB), ultra-reliable low latency communications (URLLC), massive machine-type communication (mMTC), artificial intelligence (AI) integrated communication, tactile internet, high throughput, high network capacity, high energy efficiency, low backhaul and access network congestion, and enhanced data security.

[0042] FIG. 1 illustrates a communication structure that can be provided in a 6G system according to one embodiment of the present disclosure. The embodiment of FIG. 1 can be combined with various embodiments of the present disclosure.

[0043] New network characteristics in 6G may include:

[0044] - Satellite integrated network

[0045] - Connected Intelligence: Unlike previous generations of wireless communication systems, 6G is revolutionary, upgrading the wireless evolution from "connected objects" to "connected intelligence." AI can be applied at every stage of the communication process (or at every signal processing step, as described below).

[0046] - Seamless integration of wireless information and energy transfer

[0047] - Ubiquitous super 3D connectivity: Access to networks and core network functions of drones and very low Earth orbit satellites will create super 3D connectivity in 6G ubiquitous.

[0048] Some general requirements for the new network characteristics of 6G, such as the above, may be as follows:

[0049] - small cell networks

[0050] - Ultra-dense heterogeneous network

[0051] - High-capacity backhaul

[0052] - Radar technology integrated with mobile technology: High-precision localization (or location-based services) through communications is a key feature of 6G wireless communication systems. Therefore, radar systems will be integrated with 6G networks.

[0053] - Softwarization and virtualization

[0054] Below, the core implementation technologies of the 6G system are described.

[0055] - Artificial Intelligence: Incorporating AI into communications can streamline and improve real-time data transmission. AI can use numerous analytics to determine how complex target tasks should be performed. This means AI can increase efficiency and reduce processing delays. Time-consuming tasks such as handovers, network selection, and resource scheduling can be performed instantly using AI. AI can also play a crucial role in machine-to-machine (M2M), machine-to-human, and human-to-machine communications. Furthermore, AI can facilitate rapid communication in brain-computer interfaces (BCIs). AI-based communication systems can be supported by metamaterials, intelligent structures, intelligent networks, intelligent devices, intelligent cognitive radios, self-sustaining wireless networks, and machine learning.

[0056] - THz communication (terahertz communication): Data rates can be increased by increasing the bandwidth. This can be achieved by utilizing sub-THz communication with a wide bandwidth and applying advanced massive MIMO technology. THz waves, also known as sub-millimeter waves, typically refer to the frequency range between 0.1 THz and 10 THz with corresponding wavelengths ranging from 0.03 mm to 3 mm. The 100 GHz to 300 GHz band (Sub-THz band) is considered a major portion of the THz band for cellular communications. Adding the Sub-THz band to the mmWave band will increase the capacity of 6G cellular communications. Among the defined THz bands, 300 GHz to 3 THz lies in the far infrared (IR) frequency band. While part of the optical band, the 300 GHz to 3 THz band lies at the boundary of the optical band, immediately following the RF band. Therefore, this 300 GHz to 3 THz band exhibits similarities to RF. Figure 2 illustrates the electromagnetic spectrum according to one embodiment of the present disclosure. The embodiment of FIG. 2 can be combined with various embodiments of the present disclosure. Key characteristics of THz communications include (i) widely available bandwidth to support very high data rates, and (ii) high path loss at high frequencies (highly directional antennas are essential). The narrow beamwidth generated by the highly directional antenna reduces interference. The small wavelength of THz signals allows for a much larger number of antenna elements to be integrated into devices and base stations operating in this band. This enables the use of advanced adaptive array technologies to overcome range limitations.

[0070] Unmanned aerial vehicles (UAVs): UAVs, or drones, will be a key element in 6G wireless communications. In most cases, high-speed data wireless connectivity can be provided using UAV technology. Base stations (BSs) can be installed on UAVs to provide cellular connectivity. UAVs may offer specific capabilities not found in fixed BS infrastructure, such as easy deployment, robust line-of-sight links, and controlled mobility. During emergencies such as natural disasters, deploying terrestrial communications infrastructure is not economically feasible and sometimes cannot provide services in volatile environments. UAVs can easily handle these situations. UAVs will become a new paradigm in wireless communications. This technology facilitates three fundamental requirements for wireless networks: enhanced mobile broadband (eMBB), URLLC, and mMTC. UAVs can also support various purposes, such as enhancing network connectivity, fire detection, disaster emergency services, security and surveillance, pollution monitoring, parking monitoring, and accident monitoring. Therefore, UAV technology is recognized as one of the most important technologies for 6G communications.

[0071] - Advanced air mobility (AAM): AAM is a higher concept than urban air mobility (UAM), which is an air transportation method available in urban areas, and can refer to a means of transportation that includes movement between regional hubs as well as urban areas.

[0072] - Autonomous driving (self-driving): V2X (vehicle to everything), a key element in building autonomous driving infrastructure, can be a technology that allows cars to communicate and share with various elements on the road for autonomous driving, such as vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) wireless communication. Fast transmission speeds and low-latency technologies are essential to maximize autonomous driving performance and ensure high safety. Furthermore, in the future, autonomous driving will go beyond simply providing warnings or guidance messages to drivers and may require active intervention in vehicle operation and direct control of the vehicle in dangerous situations. To this end, the amount of information that needs to be transmitted and received may become enormous, so 6G is expected to maximize autonomous driving with faster transmission speeds and lower latency than 5G.

[0073] - Non-terrestrial networks (NTN): NTN may refer to a network or network segment that uses radio frequency (RF) resources mounted on a satellite (or unmanned aerial system (UAS) platform). FIG. 3 illustrates an example of a typical NTN scenario based on a transparent payload according to an embodiment of the present disclosure. FIG. 4 illustrates an example of a typical NTN scenario based on a regenerative payload according to an embodiment of the present disclosure. The embodiments of FIG. 3 or FIG. 4 may be combined with various embodiments of the present disclosure. Referring to FIG. 3, a satellite (or UAS platform) may create a service link with a UE. The satellite (or UAS platform) may be connected to a gateway via a feeder link. The satellite may be connected to a data network via the gateway. A beam footprint may refer to an area where a signal transmitted by a satellite can be received. Referring to Figure 4, a satellite (or UAS platform) can establish a service link with a UE. A satellite (or UAS platform) connected to a UE can be connected to another satellite (or UAS platform) via an inter-satellite link (ISL). The other satellite (or UAS platform) can be connected to a gateway via a feeder link. Based on the playback payload, a satellite can be connected to a data network through another satellite and the gateway. If an ISL does not exist between a satellite and another satellite, a feeder link between the satellite and the gateway may be required. Figures 3 and 4 are merely examples of NTN scenarios, and NTN can be implemented based on various scenarios.For example, a satellite (or UAS platform) may implement a transparent or regenerative (with onboard processing) payload. For example, a satellite (or UAS platform) may generate multiple beams over a designated service area depending on the field of view of the satellite (or UAS platform). For example, the field of view of the satellite (or UAS platform) may vary depending on the onboard antenna diagram and minimum elevation angle. For example, a transparent payload may include radio frequency filtering, frequency conversion, and amplification. Therefore, the waveform signal repeated by the payload may not be altered. For example, a regenerative payload may include radio frequency filtering, frequency conversion and amplification, demodulation / decoding, switching and / or routing, and coding / modulation. For example, a regenerative payload may be substantially equivalent to equipping the satellite (or UAS platform) with all or part of the base station functionality.

[0074] - Integrated Sensing and Communication (ISAC): Wireless sensing is a technology that uses radio frequencies to determine the instantaneous linear velocity, angle, distance (range), etc. of an object, thereby obtaining information about the characteristics of the environment and / or objects within the environment. Because radio frequency sensing does not require a device to connect to the object through a network, it can provide a service for object positioning without a device. The ability to obtain range, velocity, and angle information from radio frequency signals can enable a wide range of new capabilities, such as various object detection, object recognition (e.g., vehicles, humans, animals, UAVs), and high-precision localization, tracking, and activity recognition. Wireless sensing services can provide information to a variety of industries (e.g., drones, smart homes, V2X, factories, railways, public safety, etc.), enabling applications such as intruder detection, assisted vehicle steering and navigation, trajectory tracking, collision avoidance, traffic management, and health and traffic management. In some cases, wireless sensing can utilize non-3GPP type sensors (e.g., radar, cameras) to further support 3GPP-based sensing. For example, the operation of a wireless sensing service, i.e., a sensing operation, may depend on the transmission, reflection, and scattering of wireless sensing signals. Therefore, wireless sensing may provide an opportunity to enhance existing communication systems from a communication network to a wireless communication and sensing network. FIG. 5 illustrates an example of a sensing operation according to an embodiment of the present disclosure. The embodiment of FIG. 5 may be combined with various embodiments of the present disclosure. Specifically, FIG. 5 (a) illustrates an example of sensing using a sensing receiver and a sensing transmitter located at the same location (e.g., monostatic sensing), and FIG. 5 (b) illustrates an example of sensing using a separated sensing receiver and a sensing transmitter (e.g., bistatic sensing).

[0075] The layers of the radio interface protocol between the terminal and the network can be divided into L1 (layer 1), L2 (layer 2), and L3 (layer 3) based on the three lower layers of the Open System Interconnection (OSI) standard model, which is widely known in communication systems. Among these, the physical layer belonging to layer 1 provides an information transfer service using a physical channel, and the RRC (Radio Resource Control) layer located in layer 3 controls radio resources between the terminal and the network. To this end, the RRC layer exchanges RRC messages between the terminal and the base station.

[0076] The physical layer provides information transmission services to higher layers using physical channels. The physical layer is connected to the upper layer, the Medium Access Control (MAC) layer, via a transport channel. Data travels between the MAC layer and the physical layer through the transport channel. Transport channels are classified based on how and with what characteristics data is transmitted over the wireless interface.

[0077] Data travels between different physical layers, i.e., between the physical layers of a transmitter and a receiver, via a physical channel. This physical channel can be modulated using Orthogonal Frequency Division Multiplexing (OFDM) and utilizes time and frequency as radio resources.

[0078] The MAC layer provides services to the upper layer, the radio link control (RLC) layer, through logical channels. The MAC layer provides mapping from multiple logical channels to multiple transport channels. Furthermore, the MAC layer provides logical channel multiplexing, which maps multiple logical channels to a single transport channel. The MAC sublayer provides data transmission services on logical channels.

[0079] The RLC layer performs the concatenation, segmentation, and reassembly of RLC Service Data Units (SDUs). To guarantee the various Quality of Service (QoS) required by radio bearers (RBs), the RLC layer provides three operating modes: Transparent Mode (TM), Unacknowledged Mode (UM), and Acknowledged Mode (AM). AM RLC provides error correction through automatic repeat request (ARQ).

[0080] The RRC (Radio Resource Control) layer is defined only in the control plane. The RRC layer is responsible for controlling logical channels, transport channels, and physical channels, related to the configuration, reconfiguration, and release of radio bearers. RB refers to a logical path provided by Layer 1 (physical layer or PHY layer) and Layer 2 (MAC layer, RLC layer, Packet Data Convergence Protocol (PDCP) layer, and Service Data Adaptation Protocol (SDAP) layer) for data transmission between the terminal and the network.

[0081] The functions of the PDCP layer in the user plane include the transmission of user data, header compression, and ciphering. The functions of the PDCP layer in the control plane include the transmission of control plane data and encryption / integrity protection.

[0082] The Service Data Adaptation Protocol (SDAP) layer is defined only in the user plane. The SDAP layer performs mapping between QoS flows and data radio bearers, and marking QoS flow identifiers (IDs) within downlink and uplink packets.

[0083] Establishing a Radio Bearer (RB) refers to the process of defining the characteristics of the radio protocol layer and channel to provide a specific service, and setting specific parameters and operating methods for each. RBs can be further divided into two types: the Signaling Radio Bearer (SRB) and the Data Radio Bearer (DRB). The SRB is used as a channel to transmit RRC messages in the control plane, while the DRB is used as a channel to transmit user data in the user plane.

[0084] When an RRC connection is established between the RRC layer of the terminal and the RRC layer of the base station, the terminal is in the RRC_CONNECTED state. Otherwise, it is in the RRC_IDLE state. For NR, the RRC_INACTIVE state is additionally defined, and a terminal in the RRC_INACTIVE state can maintain a connection with the core network while releasing the connection with the base station.

[0085] Downlink transmission channels that transmit data from the network to the terminal include the Broadcast Channel (BCH), which transmits system information, and the downlink Shared Channel (SCH), which transmits user traffic or control messages. Traffic or control messages for downlink multicast or broadcast services may be transmitted through the downlink SCH or a separate downlink Multicast Channel (MCH). Meanwhile, uplink transmission channels that transmit data from the terminal to the network include the Random Access Channel (RACH), which transmits initial control messages, and the uplink Shared Channel (SCH), which transmits user traffic or control messages.

[0086] Logical channels that are located above the transport channel and are mapped to the transport channel include the Broadcast Control Channel (BCCH), Paging Control Channel (PCCH), Common Control Channel (CCCH), Multicast Control Channel (MCCH), and Multicast Traffic Channel (MTCH).

[0087] Radio frames can be used for uplink and downlink transmission. A radio frame has a length of 10 ms and can be defined as two 5 ms half-frames (HF). A half-frame can contain five 1 ms subframes (SF). A subframe can be divided into one or more slots, and the number of slots within a subframe can be determined by the subcarrier spacing (SCS). Each slot can contain 12 or 14 OFDM (A) symbols, depending on the cyclic prefix (CP).

[0088] When normal CP is used, each slot can contain 14 symbols. When extended CP is used, each slot can contain 12 symbols. Here, the symbols can include OFDM symbols (or CP-OFDM symbols), SC-FDMA (Single Carrier - FDMA) symbols (or DFT-s-OFDM (Discrete Fourier Transform-spread-OFDM) symbols).

[0089] Table 2 below shows the number of symbols per slot (N) depending on the SCS setting (u) when normal CP or extended CP is used. slot symb ), number of slots per frame (N frame,u slot ) and the number of slots per subframe (N subframe,u slot ) is an example.

[0091] FIG. 6 illustrates a slot structure of a frame according to an embodiment of the present disclosure. The embodiment of FIG. 6 can be combined with various embodiments of the present disclosure.

[0092] Referring to FIG. 6, a slot includes multiple symbols in the time domain.

[0093] A carrier includes 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 ((Physical) Resource Blocks) in the frequency domain, and can correspond to one numerology (e.g., SCS, CP length, etc.). A carrier can include up to N (e.g., 5) BWPs. Data communication can be performed through activated BWPs. Each element can be referred to as a Resource Element (RE) in the resource grid, and one complex symbol can be mapped to it.

[0094] A Bandwidth Part (BWP) can be a contiguous set of physical resource blocks (PRBs) for a given numerology. A PRB can be selected from a contiguous subset of common resource blocks (CRBs) for a given numerology on a given carrier.

[0095] FIG. 7 illustrates an example of a BWP according to an embodiment of the present disclosure. The embodiment of FIG. 7 can be combined with various embodiments of the present disclosure. In the embodiment of FIG. 7, it is assumed that there are three BWPs.

[0096] Referring to Figure 7, a common resource block (CRB) may be a carrier resource block numbered from one end of a carrier band to the other. Furthermore, a PRB may be a numbered resource block within each BWP. Point A may indicate a common reference point for the resource block grid.

[0097] BWP is point A, offset from point A (N startBWP ) and bandwidth (N size BWP ) can be set by. For example, point A can be an outer reference point of the PRB of a carrier where subcarrier 0 of all numerologies (e.g., all numerologies supported by the network on that carrier) aligns. For example, the offset can be the PRB spacing between the lowest subcarrier in a given numerology and point A. For example, the bandwidth can be the number of PRBs in a given numerology.

[0098] SLSS (Sidelink Synchronization Signal) is a SL (sidelink) specific sequence and may include PSSS (Primary Sidelink Synchronization Signal) and SSSS (Secondary Sidelink Synchronization Signal). The PSSS may be referred to as S-PSS (Sidelink Primary Synchronization Signal) and the SSSS may be referred to as S-SSS (Sidelink Secondary Synchronization Signal). For example, length-127 M-sequences may be used for S-PSS and length-127 Gold sequences may be used for S-SSS. For example, a terminal may detect an initial signal (signal detection) and obtain synchronization using S-PSS. For example, the terminal can obtain detailed synchronization using S-PSS and S-SSS and detect a synchronization signal ID.

[0099] PSBCH (Physical Sidelink Broadcast Channel) may be a (broadcast) channel that transmits basic (system) information that a terminal must know first before transmitting or receiving an SL signal. For example, the basic information may be information related to SLSS, duplex mode (DM), TDD UL / DL (Time Division Duplex Uplink / Downlink) configuration, resource pool-related information, type of application related to SLSS, subframe offset, broadcast information, etc. For example, in order to evaluate PSBCH performance, in NR V2X, the payload size of PSBCH may be 56 bits, including a 24-bit CRC (Cyclic Redundancy Check).

[0100] S-PSS, S-SSS and PSBCH may be included in a block format supporting periodic transmission (e.g., SL SS (Synchronization Signal) / PSBCH block, hereinafter referred to as S-SSB (Sidelink-Synchronization Signal Block)). The S-SSB may have the same numerology (i.e., SCS and CP length) as the PSCCH (Physical Sidelink Control Channel) / PSSCH (Physical Sidelink Shared Channel) in the carrier, and the transmission bandwidth may be within a (pre-)configured SL BWP (Sidelink BWP). For example, the bandwidth of the S-SSB may be 11 RBs (Resource Blocks). For example, the PSBCH may span 11 RBs. And, the frequency location of the S-SSB may be (pre-)configured. Therefore, the terminal does not need to perform hypothesis detection in the frequency to discover the S-SSB in the carrier.

[0101] In this specification, PSCCH may be replaced by a control channel, a physical control channel, a sidelink-related control channel, a sidelink-related physical control channel, etc. In this specification, PSSCH may be replaced by a shared channel, a physical shared channel, a sidelink-related shared channel, a sidelink-related physical shared channel, etc.

[0102] FIG. 8 illustrates a procedure for a terminal to perform V2X or SL communication according to a resource allocation mode, according to one embodiment of the present disclosure. The embodiment of FIG. 8 may be combined with various embodiments of the present disclosure.

[0103] Referring to (a) of FIG. 8, in resource allocation mode 1, the base station may schedule SL resources to be used by the terminal for SL transmission. For example, in step S800, the base station may transmit information related to SL resources and / or information related to UL resources to the first terminal. For example, the UL resources may include PUCCH resources and / or PUSCH resources. For example, the UL resources may be resources for reporting SL HARQ feedback to the base station.

[0104] For example, a first terminal may receive information related to a dynamic grant (DG) resource and / or information related to a configured grant (CG) resource from a base station. For example, a CG resource may include a CG type 1 resource or a CG type 2 resource. In this specification, a DG resource may be a resource that a base station configures / allocates to the first terminal via downlink control information (DCI). In this specification, a CG resource may be a (periodic) resource that a base station configures / allocates to the first terminal via DCI and / or an RRC message. For example, in the case of a CG type 1 resource, the base station may transmit an RRC message including information related to the CG resource to the first terminal. For example, in the case of a CG type 2 resource, the base station may transmit an RRC message including information related to the CG resource to the first terminal, and the base station may transmit a DCI related to activation or release of the CG resource to the first terminal.

[0105] In step S810, the first terminal may transmit a PSCCH (e.g., Sidelink Control Information (SCI) or 1st-stage SCI) to the second terminal based on the resource scheduling. In step S820, the first terminal may transmit a PSSCH (e.g., 2nd-stage SCI, MAC PDU, data, etc.) related to the PSCCH to the second terminal. In step S830, the first terminal may receive a PSFCH related to the PSCCH / PSSCH from the second terminal. For example, HARQ feedback information (e.g., NACK information or ACK information) may be received from the second terminal via the PSFCH. In step S840, the first terminal may transmit / report HARQ feedback information to the base station via a PUCCH or a PUSCH. For example, the HARQ feedback information reported to the base station may be information generated by the first terminal based on the HARQ feedback information received from the second terminal. For example, the HARQ feedback information reported to the base station may be information generated by the first terminal based on a rule set in advance. For example, the DCI may be DCI for scheduling SL.

[0106] Referring to (b) of FIG. 8, in resource allocation mode 2, the terminal can determine SL transmission resources within SL resources set by the base station / network or preset SL resources. For example, the set SL resources or preset SL resources may be a resource pool. For example, the terminal can autonomously select or schedule resources for SL transmission. For example, the terminal can perform SL communication by selecting resources by itself within the set resource pool. For example, the terminal can select resources by itself within a selection window by performing sensing and resource (re)selection procedures. For example, the sensing can be performed on a subchannel basis. For example, in step S810, the first terminal that has selected resources by itself within the resource pool transmits PSCCH (e.g., SCI (Sidelink Control Information) or 1) using the resources. st -stage SCI) can be transmitted to the second terminal. In step S820, the first terminal transmits the PSSCH (e.g., 2) related to the PSCCH. nd -stage SCI, MAC PDU, data, etc.) can be transmitted to the second terminal. In step S830, the first terminal can receive a PSFCH related to the PSCCH / PSSCH from the second terminal.

[0107] Referring to (a) or (b) of FIG. 8, for example, a first terminal may transmit an SCI to a second terminal on a PSCCH. Or, for example, the first terminal may transmit two consecutive SCIs (e.g., 2-stage SCIs) to the second terminal on the PSCCH and / or the PSSCH. In this case, the second terminal may decode the two consecutive SCIs (e.g., 2-stage SCIs) to receive the PSSCH from the first terminal. In the present specification, an SCI transmitted on a PSCCH is 1 st SCI, 1st SCI, 1st -stage SCI or 1 st -stage SCI format, and the SCI transmitted on the PSSCH is 2 nd SCI, 2nd SCI, 2 nd -stage SCI or 2 nd -It can be called a stage SCI format.

[0108] Referring to (a) or (b) of FIG. 8, in step S830, the first terminal may receive a PSFCH. For example, the first terminal and the second terminal may determine PSFCH resources, and the second terminal may use the PSFCH resources to transmit HARQ feedback to the first terminal.

[0109] Referring to (a) of FIG. 8, in step S840, the first terminal may transmit SL HARQ feedback to the base station via PUCCH and / or PUSCH.

[0110] FIG. 9 illustrates a transmission spatial filter and a reception spatial filter according to an embodiment of the present disclosure. The embodiment of FIG. 9 can be combined with various embodiments of the present disclosure.

[0111] Referring to FIG. 9, a reception spatial filter (901) used by a receiving terminal for a reception operation and a transmission spatial filter (911) used by a transmitting terminal for a transmission operation are shown.

[0112] For example, a receiving spatial filter can only pass signals with the same beam direction as 903. That is, the receiving terminal can only receive transmissions performed based on a beam having a direction of 903.

[0113] Therefore, transmissions of 906 transmitted based on a beam having a different beam direction from that of 903 may not pass through the reception spatial filter. Signal 904, which is transmitted based on a beam having the same beam direction as that of 903, may pass through the reception spatial filter and be received by the receiving terminal.

[0114] For example, a receiving spatial filter may have a beam size / thickness of 902 and may only pass signals transmitted based on beams within the beam size / thickness. That is, a receiving terminal may only receive transmissions transmitted based on beams having a size / thickness within the beam size / thickness of 902.

[0115] Accordingly, among the signal components transmitted based on a beam having a size / thickness greater than that of 902, transmissions of 905 that contact the reception spatial filter outside the size / thickness of 902 may not pass through the reception spatial filter. Since 904 contacted the reception spatial filter within a range included in the size / thickness of 902, it can pass through the reception spatial filter and be received by the receiving terminal. On the other hand, since 905 contacted the reception spatial filter outside the size / thickness of 902, it cannot pass through the reception spatial filter and be received by the receiving terminal.

[0116] For example, 904 can be received by the receiving terminal because it is in contact with the receiving spatial filter within a range included in the size / thickness of 902 and has the same beam direction (903) as that passed by the receiving spatial filter. Here, for example, if the transmissions of 904 are all components transmitted based on a specific beam (i.e., if all signal components transmitted together with 904 are successfully received by the receiving terminal), the receiving spatial filter may be a spatial filter that covers the transmission spatial filter associated with the specific beam.

[0117] For example, a transmission spatial filter can only pass signals with the same beam direction as 913. That is, when a transmission terminal performs a transmission operation based on the transmission spatial filter, all signal components (914) that pass through the transmission spatial filter and are ultimately transmitted can have the direction of 913.

[0118] Therefore, transmissions of 916 transmitted based on a beam direction different from that of 913 may not pass through the transmission spatial filter. Signal components of 914 having the same beam direction as 913 may pass through the transmission spatial filter and be transmitted to the receiving terminal.

[0119] For example, a transmission spatial filter may have a beam size / thickness of 912 and may only pass signal components included within the beam size / thickness. That is, when a transmission terminal performs a transmission operation based on the transmission spatial filter, only signal components included within the size / thickness of 912 may pass through the transmission spatial filter and be ultimately transmitted.

[0120] Therefore, signal components that are not included in the size / thickness of 912 may not pass through the transmission spatial filter. Since 914 is a signal component included in the size / thickness of 912, it can pass through the transmission spatial filter and be transmitted to the receiving terminal. On the other hand, since 915 is a signal component that is not included in the size / thickness of 912, it cannot pass through the transmission spatial filter and cannot be transmitted to the receiving terminal.

[0121] For example, 914 may be transmitted to the receiving terminal as signal components that are included in the size / thickness of 912 and are identical to the beam direction (913) that the transmission spatial filter passes through. Here, for example, if the transmissions of 914 all pass through the receiving spatial filter that the receiving terminal uses for receiving operation (i.e., if the direction of the signal components of 914 is identical to the beam direction related to the receiving spatial filter and the signal components of 914 are all included in the size / thickness of the receiving spatial filter), the receiving spatial filter may be a spatial filter that covers the transmission spatial filter of 911.

[0122] FIG. 10 illustrates a method for determining whether a receiving spatial filter covers a transmitting spatial filter, according to an embodiment of the present disclosure. The embodiment of FIG. 10 may be combined with various embodiments of the present disclosure.

[0123] Referring to FIG. 10, a reception spatial filter (1001) used by a receiving terminal for a reception operation and a transmission spatial filter (1011) used by a transmitting terminal for a transmission operation are shown.

[0124] For example, the direction of the signal components that the receiving spatial filter passes through may be 1003, and the direction of the signal components that are transmitted through the transmitting spatial filter may be 1013. For example, the receiving beam direction associated with the receiving spatial filter may be 1003, and the transmitting beam direction associated with the transmitting spatial filter may be 1013.

[0125] For example, the size / thickness of the receiving spatial filter may be 1002. That is, the receiving spatial filter passes only signal components included within 1002, and only signal components that pass through the receiving spatial filter can be received by the receiving terminal.

[0126] For example, the size / thickness of the transmission spatial filter may be 1012. That is, the transmission spatial filter passes only signal components included within 1012, and only signal components that pass through the transmission spatial filter can be transmitted to the receiving terminal.

[0127] 1021 and 1022 are cross-sectional views of the size / thickness of the transmission spatial filter or the size / thickness of the reception spatial filter.

[0128] For example, if the above 1021 is the size / thickness of the transmission spatial filter, the above 1022 is the size / thickness of the reception spatial filter, and since the above 1022 is included in the above 1021, the size / thickness of the transmission spatial filter is larger than the size / thickness of the reception spatial filter, so some of the signal components transmitted to the receiving terminal through the transmission spatial filter may not pass through the reception spatial filter. In this case, the reception spatial filter may be a spatial filter that does not cover the transmission spatial filter.

[0129] Conversely, for example, if the 1021 is the size / thickness of the receiving spatial filter, the 1022 is the size / thickness of the transmitting spatial filter, and since the 1022 is included in the 1021, the size / thickness of the transmitting spatial filter is smaller than the size / thickness of the receiving spatial filter, so all signal components transmitted to the receiving terminal through the transmitting spatial filter can pass through the receiving spatial filter. In this case, the receiving spatial filter may be a spatial filter that covers the transmitting spatial filter.

[0130] 1031 represents the receiving beam direction related to 1003, that is, the receiving spatial filter, and 1032 represents the transmitting beam direction related to 1013, that is, the transmitting spatial filter. For example, only when 1031 and 1032 are horizontal as shown in the drawing can all signal components transmitted by the transmitting terminal based on the transmitting spatial filter pass through the receiving spatial filter. Therefore, only when 1031 and 1032 are horizontal can all signal components transmitted to the receiving terminal through the transmitting spatial filter pass through the receiving spatial filter. The receiving spatial filter can be said to be a spatial filter that covers the transmitting spatial filter.

[0131] Meanwhile, in terminal-to-terminal communication (e.g., sidelink communication; SL communication), a terminal may perform transmission (and / or reception) based on multiple panels and / or beam directions, and in this case, a method for managing spatial settings, including information related to the beam or information about a spatial domain transmission / reception filter, may need to be defined.

[0132] Meanwhile, in the case of base station-to-terminal communication (e.g., downlink communication; DL communication), the base station can instruct the terminal about antenna port QCL (quasi-co-location) information through a transmission configuration indicator (e.g., transmission configuration indicator; TCI), and in particular, when a base station-to-terminal (e.g., DL) signal is received through 'typeD', the base station can configure / instruct whether the terminal assumes that spatial reception parameters or beam information are identical to a specific SSB or channel state information reference signal (e.g., CSI-RS).

[0133] Meanwhile, in the case of terminal-to-base station communication (e.g., uplink communication; UL communication), the base station may configure / instruct the terminal's spatial configuration or spatial domain transmission filter for physical uplink shared channel (e.g., PUSCH) transmission to follow the terminal's specific SRS transmission resource, physical random access channel (e.g., PRACH) transmission, and / or the spatial configuration for base station-to-terminal signal (e.g., DL) reception.

[0134] Meanwhile, in the case of base station-to-terminal communication (e.g., DL communication), beam management and / or beam compensation (beam recovery) operations may be performed based on a random access procedure including transmission of a specific candidate beam reference signal (RS) and a physical random access channel. On the other hand, in the case of terminal-to-terminal communication (e.g., SL communication), since there is no channel type such as a physical random access channel, a method using a different terminal-to-terminal communication (e.g., SL communication) channel / signal type may be required for beam management and / or beam compensation procedures.

[0135] For example, in a beam management and / or beam compensation procedure in base station-to-terminal communication (e.g., DL communication), the terminal may measure reference signal received power (e.g., reference signal received power; RSRP) for a candidate beam reference signal, and select a physical random access channel preamble for a specific candidate beam reference signal based on the reference signal received power (e.g., RSRP) measurement value and transmit the physical random access channel preamble to the base station.

[0136] For example, after the terminal transmits one or more physical random access channels using different transmission spatial settings, the terminal may receive a physical base station-to-terminal control channel (e.g., PDCCH) scrambled with a cell radio network temporary identifier (C-RNTI) from the base station within a random access response (RAR) window, in which case the terminal may determine that the random access procedure for beam failure recovery has been successfully completed.

[0137] Meanwhile, a terminal performing terminal-to-terminal communication (e.g., SL communication) may exist within the coverage of a specific base station or cell, and in particular, when terminal-to-terminal communication (e.g., SL communication) is performed on a licensed band, terminal-to-terminal channel (e.g., SL channel) transmission may cause high interference to terminal-to-base station communication (e.g., UL communication).

[0138] Meanwhile, in cases where terminal-to-base station transmission (e.g., UL transmission) and terminal-to-terminal transmission (e.g., SL transmission) are performed (simultaneously) based on specific beams or spatial settings in FR2, etc., mutual interference may be minimal depending on the spatial settings used for each transmission, even if all or part of the resources between the mutual transmissions overlap. In other words, if the spatial settings are appropriately determined, two transmissions can be performed simultaneously on the overlapping resources.

[0139] According to one embodiment of the present disclosure, a terminal may receive specific spatial configuration information from a base station, and the terminal may not use a beam or spatial configuration that covers a beam or beam direction corresponding to the specific spatial configuration for a specific time domain. That is, the terminal may use a beam or spatial configuration that does not cover a beam or beam direction corresponding to the specific spatial configuration in a specific time domain.

[0140] For example, the specific spatial configuration may be a spatial configuration for terminal-to-base station transmission (e.g., UL transmission) between a terminal and a base station, and / or may be in the form of an SRI (SRS resource indication), a specific base station-to-terminal reference signal (e.g., DL RS) and QCL information therefor (particularly, TypeD), a specific physical random access channel (e.g., PRACH) resource and / or spatial configuration information for physical random access channel (e.g., PRACH) transmission, etc.

[0141] And / or, for example, the information may be RRC-configured from the base station and / or indicated via a MAC message and / or indicated via base station-to-terminal control information (e.g., DCI).

[0142] For example, in the case of a terminal operating in Mode 1 (or, for example, being configured with resources to use), the RRC configuration and / or base station-to-terminal control information (e.g., DCI) may indicate / schedule / configure terminal-to-terminal resources (e.g., SL resources), and / or the use of spatial configurations associated with the specific spatial configuration may be restricted for all or part of the indicated / scheduled / configured (time and / or frequency) resources.

[0143] For example, the specific time domain may be RRC-configured by the base station, indicated via a MAC message, and / or indicated via base station-to-terminal control information (e.g., DCI). Accordingly, the base station may limit the spatial configuration used for terminal-to-terminal transmission (e.g., SL transmission) and / or reception, and / or perform base station-to-terminal transmission (e.g., DL transmission) on terminal-to-terminal resources (e.g., SL resources) or allow / schedule terminal-to-base station resources (e.g., UL resources) (to other terminals).

[0144] According to one embodiment of the present disclosure, a terminal may not use a beam or spatial configuration covering a beam or beam direction corresponding to a specific spatial configuration that can be used in base station-to-terminal communication (e.g., DL communication) and / or terminal-to-base station communication (e.g., UL communication) set at a base station, for all or part of a time domain.

[0145] For example, the specific spatial configuration may be associated with a transmission configuration indicator (e.g., TCI) value that is set or used for all or part of a CORESET. For example, the part of the CORESET may be for a PCell, or may include all or part of a CSS, or may correspond to CORESET#0, or may be for a CORESET within an initial partial bandwidth (e.g., BWP), and / or may be separately indicated / set by the base station.

[0146] For example, the CSS may correspond to Type 0 (at least, RMSI (SIB1)), Type 0a (OSI (other system information)), Type 1 (random access procedure), Type 2 (paging), Type 0B, Type 1A, Type 2A, and / or Type 3. For example, the time domain for the operation restriction may be all or part of the target base station-to-terminal communication (e.g., DL communication) operation time interval.

[0147] For example, the specific spatial configuration may be associated with a transmission configuration indicator (e.g., TCI) value that is configured or used for a specific terminal-to-base station transmission (e.g., UL transmission). For example, the specific terminal-to-base station transmission (e.g., UL transmission) may be a physical random access channel (e.g., PRACH), a terminal-to-base station physical control channel (e.g., PUCCH), an SRS, and / or a random access procedure-related terminal-to-base station communication (e.g., UL communication) and / or something that is instructed / configured by the base station.

[0148] For example, the target terminal-to-base station communication (e.g., UL communication) may differ depending on whether it is PCell or SCell, depending on whether it is 4-step or 2-step, depending on whether it is PDCCH-order-based, depending on the transmission purpose (initial access, beam management), depending on the terminal-to-base station control information (e.g., UCI) type, depending on the priority index (e.g., whether it is eMBB or URLLC), and / or depending on the time operation method such as aperiodic operation or periodic operation.

[0149] For example, the time period for the above-mentioned operation restriction may be all or part of the target terminal-to-base station communication (e.g., UL communication) operation time period. For example, the terminal-to-base station communication (e.g., UL communication) operation time period may be after the application of TA at the terminal end and / or before the application of TA.

[0150] For example, the terminal may report to the base station all or part of the spatial configuration used during terminal-to-terminal transmission (e.g., SL transmission) and / or reception, and / or the spatial configuration may be in the form of an SRI (SRS resource indication) for the terminal and the base station, a specific base station-to-terminal reference signal (e.g., DL RS) and QCL information therefor (in particular, TypeD), a specific physical random access channel (e.g., PRACH) resource and / or spatial configuration information for physical random access channel (e.g., PRACH) transmission, and / or the spatial configuration to be reported may be associated with, cover, and / or be covered by a spatial configuration for terminal-to-terminal communication (e.g., SL communication) in terms of a beam or beam direction.

[0151] For example, the spatial settings for the terminal-to-terminal transmission (e.g., SL transmission) and / or reception may be information that the terminal is using at the time of reporting to the base station, may be all or part of the information that the terminal can use for terminal-to-terminal communication (e.g., SL communication), and / or may be information to be used in a specific time domain.

[0152] For example, information regarding the specific time zone can be separately reported by the terminal to the base station. Accordingly, the base station can perform appropriate scheduling by considering interference with the terminal's terminal-to-terminal transmission (e.g., SL transmission), base station-to-terminal communication (e.g., DL communication) based on reception, and / or terminal-to-base station communication (e.g., UL communication).

[0153] FIG. 11 illustrates a procedure for performing new device-to-device communication while reducing interference that a transmitting terminal may cause to existing device-to-device communication, according to one embodiment of the present disclosure. The embodiment of FIG. 11 may be combined with various embodiments of the present disclosure.

[0154] Referring to FIG. 11, in step S1110, the first device may receive information about a first spatial setting from the second device. For example, the first spatial setting may be a transmission spatial setting or a reception spatial setting used by the first device when performing communication (e.g., SL transmission, UL transmission, or DL ​​reception) with the second device.

[0155] In step S1120, the first device can acquire a second spatial setting that does not cause interference with the communication based on the first spatial setting. For example, the second spatial setting can be set so as not to cover the first spatial setting. That is, the second spatial setting can be set so that the direction of the second beam (and / or the second spatial filter) associated with the second spatial setting is not parallel to the direction of the first beam (and / or the first spatial filter) associated with the first spatial setting (i.e., the directions are not the same or opposite). And / or, for example, the second spatial setting may be set such that the degree (ratio) of overlap between a signal component of a transmission performed based on a second beam (and / or a second spatial filter) associated with the second spatial setting and the direction of a first beam (and / or a first spatial filter) associated with the first spatial setting is less than or equal to a threshold value.

[0156] In step S1130, the first device can perform device-to-device transmission (e.g., SL transmission) to the third device based on the second spatial filter associated with the second spatial setting. Through this embodiment, the second spatial filter used for the transmission performed to the third device can be set to cause less interference to the communications performed by the first device and the second device, and thus, two or more communications can be performed on the same resource, so that wireless communication resources can be used more efficiently.

[0157] For example, the second device may be a base station, and the first device and the third device may be terminals.

[0158] FIG. 12 illustrates a spatial filter that enables a transmitting terminal to perform new device-to-device communication while reducing interference with existing device-to-device communication, according to one embodiment of the present disclosure. The embodiment of FIG. 12 may be combined with various embodiments of the present disclosure.

[0159] Referring to FIG. 12, a first device and a second device having the same relationship as in FIG. 11 are shown. That is, the first device may be a device that performs wireless communication with the second device and attempts to transmit to a third device.

[0160] In FIG. 12, 1201 may represent a transmission spatial filter used in a transmission performed by the first device to the second device. 1202 may represent a reception spatial filter associated with a first reception spatial configuration used by the second device when performing a reception operation from the first device. 1201 and 1202 may have opposite directions.

[0161] Here, the first device needs to determine a spatial filter to use when performing a transmission to the third device, and the first device can determine the spatial filter so that the transmission performed to the third device has a minimal impact on the transmission performed between the first device and the second device. For example, it is assumed here that the candidate spatial filters that the first device can select are the second spatial filter and the third spatial filter.

[0162] 1211 represents the direction and signal component of the beam related to the second spatial filter. 1211 may be the sum of the signal component of 1212 and the signal component of 1213, and the direction of 1212 may be the same as the direction of 1201, and the direction of 1213 may be perpendicular to 1212. That is, among the signal components of transmission performed based on 1211, the signal component of 1212 may be a component that may affect communication performed by the first device with the second device.

[0163] 1221 represents the direction and signal components of the beam associated with the third spatial filter. 1221 may be the sum of the signal components of 1222 and 1223, and the direction of 1222 may be identical to the direction of 1201, and the direction of 1223 may be perpendicular to 1222. That is, among the signal components of transmission performed based on 1221, the signal component of 1222 may be a component that may affect communication performed by the first device with the second device.

[0164] Here, when transmission is performed based on the second spatial filter, the first "ratio of total signal components to interference signal components" may be 1212 / 1211, and when transmission is performed based on the third spatial filter, the second "ratio of total signal components to interference signal components" may be 1222 / 1221. Here, since the second "ratio of total signal components to interference signal components" is smaller than the first "ratio of total signal components to interference signal components," the first device may perform transmission to the third device based on the third spatial filter. That is, the first device may determine to use a third spatial setting associated with the third spatial filter to perform transmission to the third device. That is, the first device may determine to use a spatial setting associated with a spatial filter having a smallest "ratio of total signal components to interference signal components" among the candidate spatial settings.

[0165] For example, when a transmitting terminal determines / judges a beam failure and / or receives a beam failure situation from a receiving terminal, the terminal may report the beam failure situation to the base station, and / or the report may include terminal-to-terminal carrier (e.g., SL carrier) information where the beam failure occurred, terminal-to-terminal partial bandwidth (e.g., SL BWP) information, and transmission and / or reception resource pool information.

[0166] For example, a transmitting terminal may request a base station to return or release all or part of the terminal-to-terminal transmission (e.g., SL transmission) resource allocation in the dynamic grant (DG) and / or established grant (CG) manner.

[0167] For example, a transmitting terminal may request / provide the base station with information that it will not perform actual transmission for all or part of terminal-to-terminal transmission (e.g., SL transmission) resource allocation in the dynamic grant (DG) and / or configured grant (CG) manner and / or target resource set and / or time interval information.

[0168] For example, a terminal may request a base station to allocate resources for transmitting (periodic and / or semi-persistent) channel state information reference signals (e.g., CSI-RS) and / or beam-related reference signals (e.g., RS) (at least for beam failure recovery purposes) and / or request resource release.

[0169] For example, when a terminal requests a base station for terminal-to-terminal resources (e.g., SL resources), the terminal may request or report the pool type (dedicated pool, shared pool) for the terminal-to-terminal resource (e.g., SL resources) request and / or the purpose of the beam reference signal (e.g., RS) (initial beam pairing, beam maintenance, beam failure detection, beam failure recovery), the configuration of the reference signal (e.g., RS), or the resource type of the reference signal (e.g., RS). This operation may be intended to allow the base station to efficiently determine allocation of reference signal (e.g., RS) resources in a situation where the terminal can know the amount of reference signal (e.g., RS) overhead for beam management.

[0170] For example, a terminal may (depending on the specific situation) omit actual reference signal (e.g., RS) transmission from resources allocated from a base station for transmission of (periodic and / or semi-periodic) channel state information reference signals (e.g., CSI-RS) and / or beam-related reference signals (e.g., RS).

[0171] For example, the above-mentioned specific situation may be determined by the terminal implementation and / or may include a case where instances where the beam quality is above a certain level occur above a certain level or a certain number of times. This case may be a case where the terminal determines that the beam information does not need to be dynamically changed, and in this case, the terminal may omit actual reference signal (e.g., RS) transmission to reduce reference signal (e.g., RS) overhead.

[0172] According to one embodiment of the present disclosure, when a base station allocates terminal-to-terminal resources (e.g., SL resources) to a terminal in a dynamic grant (DG) manner (a manner using base station-to-terminal control information (e.g., DCI)), the field configuration of the base station-to-terminal control information (e.g., DCI) format 3_0 or the base station-to-terminal control information (e.g., DCI) format for terminal-to-terminal resource (e.g., SL resources) allocation may be different depending on the resource pool index value. This may be the case where the resource pool type is distinguished by the resource pool index, and the base station-to-terminal control information (e.g., DCI) configuration field may be different depending on the resource pool type.

[0173] For example, when a base station allocates terminal-to-terminal resources (e.g., SL resources) to a terminal using a dynamic grant (DG) method (using base station-to-terminal control information (e.g., DCI)), the field configuration of the base station-to-terminal control information (e.g., DCI) format 3_0 or the base station-to-terminal control information (e.g., DCI) format for terminal-to-terminal resource (e.g., SL resource) allocation may be different depending on the resource pool type indication value or the third flag value.

[0174] For example, the base station-to-terminal control information (e.g., DCI) configuration may differ depending on whether the resource pool index value corresponds to a resource pool for beam-related reference signal (e.g., RS) transmission, whether it corresponds to a resource pool that allows terminal-to-terminal physical channel (e.g., PSCCH / PSSCH) transmission, and / or whether it corresponds to a resource pool that allows transport block (e.g., TB) or data transmission.

[0175] For example, the size of a base station-to-terminal control information (e.g., DCI) format for beam-related terminal-to-terminal communication (e.g., SL communication) standalone channel state information reference signal (e.g., CSI-RS) transmission resource allocation and a base station-to-terminal control information (e.g., DCI) format for general terminal-to-terminal transmission (e.g., SL transmission) (e.g., terminal-to-terminal physical channel (e.g., PSCCH / PSSCH) or transport block (e.g., TB) transmission) resource allocation may be the same, and / or, if the size of one of the above formats is large, padding bits (e.g., zero-padding) may be added to a base station-to-terminal control information (e.g., DCI) format of a smaller size to match the larger size.

[0176] In the embodiments of the present disclosure, resource allocation for standalone channel state information reference signal (e.g., CSI-RS) for terminal-to-terminal communication (e.g., SL communication) and resource allocation for general terminal-to-terminal transmission (e.g., SL transmission) have been described, but the idea of ​​the present disclosure can be extended and applied to a terminal-to-terminal resource (e.g., SL resource) allocation method for purposes other than general terminal-to-terminal transmission (e.g., SL transmission) resource allocation (e.g., standalone reference signal (e.g., PRS) or third reference signal (e.g., RS), etc.).

[0177] According to one embodiment of the present disclosure, spatial configuration information for terminal-to-terminal transmission (e.g., SL transmission) may be changed differently or independently for each cast type, unicast session, receiver for terminal-to-terminal transmission (e.g., SL transmission), terminal-to-terminal channel (e.g., SL channel) type, (transmission and / or reception) resource pool, mobility-related information of terminals (e.g., speed, velocity, direction, acceleration, position, height, etc.), transmission priority value, reception priority value, terminal-to-terminal transmission (e.g., SL transmission) with terminal-to-terminal HARQ-ACK (e.g., SL HARQ-ACK) feedback enabled / disabled, terminal-to-terminal HARQ-ACK (e.g., SL HARQ-ACK) feedback option, QoS parameter, (remaining) PDB, HARQ process, beam process, source ID, destination ID, and / or transport block (e.g., TB).

[0178] According to one embodiment of the present disclosure, spatial configuration information for terminal-to-terminal transmission (e.g., SL transmission) may be managed differently or independently for each cast type, unicast session, receiver for terminal-to-terminal transmission (e.g., SL transmission), terminal-to-terminal channel (e.g., SL channel) type, (transmission and / or reception) resource pool, mobility-related information of terminals (e.g., speed, velocity, direction, acceleration, position, height, etc.), transmission priority value, reception priority value, terminal-to-terminal transmission (e.g., SL transmission) with terminal-to-terminal HARQ-ACK (e.g., SL HARQ-ACK) feedback enabled / disabled, terminal-to-terminal HARQ-ACK (e.g., SL HARQ-ACK) feedback option, QoS parameter, (remaining) PDB, HARQ process, beam process, source ID, destination ID, and / or transport block (e.g., TB).

[0179] According to one embodiment of the present disclosure, spatial configuration information for terminal-to-terminal transmission (e.g., SL transmission) may be configured differently or independently for each cast type, unicast session, receiver for terminal-to-terminal transmission (e.g., SL transmission), terminal-to-terminal channel (e.g., SL channel) type, (transmission and / or reception) resource pool, terminal mobility-related information (e.g., speed, velocity, direction, acceleration, position, height, etc.), transmission priority value, reception priority value, terminal-to-terminal transmission (e.g., SL transmission) with terminal-to-terminal HARQ-ACK (e.g., SL HARQ-ACK) feedback enabled / disabled, terminal-to-terminal HARQ-ACK (e.g., SL HARQ-ACK) feedback option, QoS parameter, (remaining) PDB, HARQ process, beam process, source ID, destination ID, and / or transport block (e.g., TB).

[0180] According to one embodiment of the present disclosure, spatial configuration information for terminal-to-terminal transmission (e.g., SL transmission) may be indicated differently or independently for each cast type, unicast session, receiver for terminal-to-terminal transmission (e.g., SL transmission), terminal-to-terminal channel (e.g., SL channel) type, (transmission and / or reception) resource pool, terminal mobility-related information (e.g., speed, velocity, direction, acceleration, position, height, etc.), transmission priority value, reception priority value, terminal-to-terminal transmission (e.g., SL transmission) with terminal-to-terminal HARQ-ACK (e.g., SL HARQ-ACK) feedback enabled / disabled, terminal-to-terminal HARQ-ACK (e.g., SL HARQ-ACK) feedback option, QoS parameter, (remaining) PDB, HARQ process, beam process, source ID, destination ID, and / or transport block (e.g., TB).

[0181] The various methods of the present disclosure may be applied differently per unicast session (group), cast type, transmission priority value, reception priority value, terminal-to-terminal transmission (e.g., SL transmission) with terminal-to-terminal HARQ-ACK (e.g., SL HARQ-ACK) feedback enabled / disabled, terminal-to-terminal HARQ-ACK (e.g., SL HARQ-ACK) feedback option, QoS parameter, (remaining) PDB, congestion control level, terminal's mobility related information (e.g., speed, velocity, direction, acceleration, position, height, etc.) per (transmit and / or receive) resource pool, terminal-to-terminal transmission (e.g., SL transmission) or reception, HARQ process, beam process, source ID, destination ID, and / or transport block (e.g., TB).

[0182] For example, in various embodiments of the present disclosure, units of (pre-)configuration may be configured in the form of the above-described different combinations. For example, in embodiments of the present disclosure, parameter indication and management via PSCCH (and / or PSSCH) may be performed in units of the above-described different combinations.

[0183] In various embodiments of the present disclosure, spatial configuration, transmission configuration indicator (e.g., TCI) information, and / or QCL information may refer to each other. For example, spatial configuration, transmission configuration indicator (e.g., TCI) information, and / or QCL information may be interpreted as being replaced with information related to a beam, beam direction, spatial domain transmission, or receiving filter.

[0184] In various embodiments of the present disclosure, for example, having the same spatial configuration information for transmission may mean that the spatial domain transmission filters of the terminal are the same for two different transmission signals.

[0185] In various embodiments of the present disclosure, for example, having the same spatial configuration information for reception may mean that two different reception signals have a QCL 'TypeD' relationship. And / or, for example, having the same spatial configuration information for reception may mean a relationship in which two different signals use the same spatial reception parameters.

[0186] In various embodiments of the present disclosure, for example, (pre)configuration may mean pre-configuration (based on signaling from a server, or at the time of product shipment), configuration from a base station, or configuration via PC5-RRC between terminals.

[0187] The various methods of the present disclosure may be applied differently depending on the terminal-to-terminal channel (e.g., SL channel). The various methods of the present disclosure may be applied differently depending on the type of information contained in the terminal-to-terminal channel (e.g., SL channel).

[0188] The method proposed above can be applied to the devices described below. First, the processor (202) of the receiving terminal can set at least one partial bandwidth (e.g., BWP). Then, the processor (202) of the receiving terminal can control the transceiver (206) of the receiving terminal to receive a sidelink-related physical channel and / or a sidelink-related reference signal from the transmitting terminal on at least one partial bandwidth (e.g., BWP).

[0189] When terminal-to-terminal communication (e.g., SL communication) is performed in FR2, the terminal can perform transmission and / or reception operations (with the base station and / or the terminal) based on multiple panels and / or beam directions. Here, a spatial setting including the beam-related information or a spatial domain transmission / reception filter needs to be defined.

[0190] Meanwhile, existing technologies can cause high interference between terminals and base stations (e.g., UL reception) when beam-based transmission (e.g., SL transmission) occurs. Furthermore, existing technologies can waste allocated resources if a beam failure occurs.

[0191] According to one embodiment of the present disclosure, a terminal receives beam information related to terminal-base station communication (e.g., DL / UL communication) from a base station, and when performing terminal-to-terminal transmission (e.g., SL transmission) based on time interval information in which the beam will be used, the terminal can avoid using a beam that overlaps with (or covers one side of) the beam. According to one embodiment of the present disclosure, when the terminal receives resource information from the base station, in the event of a beam failure, the terminal can transmit information about the related resource to the base station, thereby performing a request for return / release of the corresponding resource.

[0192] According to various embodiments of the present disclosure, when performing beam-based terminal-to-terminal transmission (e.g., SL transmission), an effect of efficiently reducing interference that may be caused to a base station may occur.

[0246] FIG. 17 illustrates a signal processing circuit for a transmission signal according to an embodiment of the present disclosure. The embodiment of FIG. 17 can be combined with various embodiments of the present disclosure.

[0247] Referring to FIG. 17, the signal processing circuit (1000) may include a scrambler (1010), a modulator (1020), a layer mapper (1030), a precoder (1040), a resource mapper (1050), and a signal generator (1060). Although not limited thereto, the operations / functions of FIG. 17 may be performed in the processor (102, 202) and / or the transceiver (106, 206) of FIG. 16. The hardware elements of FIG. 17 may be implemented in the processor (102, 202) and / or the transceiver (106, 206) of FIG. 16. For example, blocks 1010 to 1060 may be implemented in the processor (102, 202) of FIG. 16. Additionally, blocks 1010 to 1050 may be implemented in the processor (102, 202) of FIG. 16, and block 1060 may be implemented in the transceiver (106, 206) of FIG. 16.

[0248] The codeword can be converted into a wireless signal through the signal processing circuit (1000) of FIG. 17. Here, the codeword is an encoded bit sequence of an information block. The information block can include a transport block (e.g., an UL-SCH transport block, a DL-SCH transport block). The wireless signal can be transmitted through various physical channels (e.g., a PUSCH or a PDSCH).

[0249] Specifically, the codeword can be converted into a bit sequence scrambled by a scrambler (1010). The scramble sequence used for scrambling is generated based on an initialization value, and the initialization value may include ID information of the wireless device, etc. The scrambled bit sequence can be modulated into a modulation symbol sequence by a modulator (1020). The modulation method may include pi / 2-BPSK (pi / 2-Binary Phase Shift Keying), m-PSK (m-Phase Shift Keying), m-QAM (m-Quadrature Amplitude Modulation), etc. The complex modulation symbol sequence can be mapped to one or more transmission layers by a layer mapper (1030). The modulation symbols of each transmission layer can be mapped to the corresponding antenna port(s) by a precoder (1040) (precoding). The output z of the precoder (1040) can be obtained by multiplying the output y of the layer mapper (1030) by a precoding matrix W of N*M. Here, N is the number of antenna ports, and M is the number of transmission layers. Here, the precoder (1040) can perform precoding after performing transform precoding (e.g., DFT transform) on complex modulation symbols. In addition, the precoder (1040) can perform precoding without performing transform precoding.

[0250] The resource mapper (1050) can map modulation symbols of each antenna port to time-frequency resources. The time-frequency resources can include multiple symbols (e.g., CP-OFDMA symbols, DFT-s-OFDMA symbols) in the time domain and multiple subcarriers in the frequency domain. The signal generator (1060) generates a wireless signal from the mapped modulation symbols, and the generated wireless signal can be transmitted to another device through each antenna. To this end, the signal generator (1060) can include an Inverse Fast Fourier Transform (IFFT) module, a Cyclic Prefix (CP) inserter, a Digital-to-Analog Converter (DAC), a frequency uplink converter, etc.

[0251] The signal processing process for receiving signals in a wireless device can be configured in reverse order of the signal processing process (1010 to 1060) of FIG. 17. For example, a wireless device (e.g., 100, 200 of FIG. 16) can receive wireless signals from the outside through an antenna port / transceiver. The received wireless signals can be converted into baseband signals through a signal restorer. For this purpose, the signal restorer can include a frequency downlink converter, an analog-to-digital converter (ADC), a CP remover, and a fast Fourier transform (FFT) module. Thereafter, the baseband signal can be restored to a codeword through a resource demapper process, a postcoding process, a demodulation process, and a descrambling process. The codewords can be restored to the original information blocks through decoding. Accordingly, a signal processing circuit (not shown) for a received signal may include a signal restorer, a resource de-mapper, a postcoder, a demodulator, a de-scrambler, and a decoder.
