[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.

[0039] In this specification, "configured or defined" may be interpreted as being configured or preset to a device through predefined signaling (e.g., SIB, MAC, RRC) from a base station or network. In this specification, "configured or defined" may be interpreted as being preset to a device.

[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. TDMA can be implemented with wireless technologies such as GSM (global system for mobile communications) / GPRS (general packet radio service) / EDGE (enhanced data rates for GSM evolution). OFDMA can be implemented with wireless technologies such as IEEE (Institute of Electrical and Electronics Engineers) 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802-20, E-UTRA (evolved UTRA), LTE (long term evolution), and 5G NR.

[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 within 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. It performs mapping between QoS flows and data radio bearers, marking QoS flow identifiers (IDs) within downlink and uplink packets, and more.

[0083] Establishing an RB refers to the process of defining the characteristics of the radio protocol layer and channel to provide a specific service, and setting specific parameters and operating methods for each. RBs can be further divided into two types: 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.

[0090] CP type SCS (15*2 u )N slot symb N frame,u slot N subframe,u slot Normal CP15kHz (u=0)1410130kHz (u=1)1420260kHz (u=2)14404120kHz (u=3)14808240kHz (u=4)1416016Extended CP60kHz (u=2)12404

[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 a plurality of symbols in the time domain. A carrier includes a plurality of subcarriers in the frequency domain. An RB (Resource Block) may be defined as a plurality (e.g., 12) of consecutive subcarriers in the frequency domain. A BWP (Bandwidth Part) may be defined as a plurality of consecutive (P)RBs ((Physical) Resource Blocks) in the frequency domain, and may correspond to one numerology (e.g., SCS, CP length, etc.). A carrier may include up to N (e.g., 5) BWPs. Data communication may be performed through activated BWPs. Each element may be referred to as a Resource Element (RE) in the resource grid, and one complex symbol may be mapped to it.

[0093] 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.

[0094] 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.

[0095] 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.

[0096] BWP is point A, offset from point A (N start BWP ) 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.

[0097] 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.

[0098] 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).

[0099] 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.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] 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.

[0104] 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 of SL. For example, the format of the DCI may be DCI format 3_0 or DCI format 3_1.

[0105] Below, an example of DCI format 3_0 is described.

[0106] DCI format 3_0 is used for scheduling NR PSCCH and NR PSSCH in one cell.

[0107] The following information is transmitted via DCI format 3_0 with CRC scrambled by SL-RNTI or SL-CS-RNTI.

[0116] - Configuration Index - 0 bit if the UE is not configured to monitor DCI format 3_0 with CRC scrambled by SL-CS-RNTI; otherwise, 3 bits. If the UE is configured to monitor DCI format 3_0 with CRC scrambled by SL-CS-RNTI, this field is reserved for DCI format 3_0 with CRC scrambled by SL-RNTI.

[0117] - Counter sidelink allocation index - 2 bits, 2 bits if the UE is set to pdsch-HARQ-ACK-Codebook = dynamic, 2 bits if the UE is set to pdsch-HARQ-ACK-Codebook = semi-static

[0118] - Padding bits if needed

[0119] 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.

[0120] 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, 1 st -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.

[0121] For example, 1 st -stage SCI format may include SCI format 1-A and / or SCI format 1-B, and 2 nd -stage SCI formats may include SCI Format 2-A, SCI Format 2-B, SCI Format 2-C, and / or SCI Format 2-D.

[0122] Below, an example of SCI format 1-A is described.

[0123] SCI Format 1-A is a 2-bit format on the PSSCH and PSSCH nd -stage is used for scheduling SCI.

[0150] In HARQ operation, when HARQ-ACK information contains only NACK or there is no feedback of HARQ-ACK information, SCI format 2-B is used for decoding PSSCH.

[0158] - Zone ID - 12 bits

[0159] - Communication range requirement - 4 bits determined by the upper layer parameter sl-ZoneConfigMCR-Index

[0160] 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.

[0161] 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.

[0162] Below, the HARQ (Hybrid Automatic Repeat Request) procedure is described.

[0163] For example, SL HARQ feedback can be enabled for unicast. For example, SL HARQ feedback can be enabled for groupcast. For example, two HARQ feedback options can be supported for groupcast.

[0164] (1) Groupcast Option 1: If a receiving terminal fails to decode a transport block associated with the PSCCH after decoding a PSCCH targeting the receiving terminal, the receiving terminal may transmit a negative acknowledgment (NACK) to the transmitting terminal via a PSFCH. On the other hand, if the receiving terminal decodes a PSCCH targeting the receiving terminal and successfully decodes a transport block associated with the PSCCH, the receiving terminal may not transmit a positive acknowledgment (ACK) to the transmitting terminal.

[0165] (2) Groupcast Option 2: If the receiving terminal fails to decode a transport block associated with the PSCCH after decoding the PSCCH targeting the receiving terminal, the receiving terminal can transmit a NACK to the transmitting terminal via the PSFCH. In addition, if the receiving terminal decodes the PSCCH targeting the receiving terminal and successfully decodes the transport block associated with the PSCCH, the receiving terminal can transmit an ACK to the transmitting terminal via the PSFCH.

[0166] Below, the UE procedure for reporting HARQ-ACK on the sidelink is described.

[0167] In response to receiving the PSSCH, the UE transmits a PSFCH containing HARQ-ACK information, N PSSCH subch The SCI format may be indicated by scheduling PSSCH reception on one or more subchannels from the subchannel number. The UE provides HARQ-ACK information including ACK, NACK, or NACK only.

[0168] The UE may be provided with the number of slots in the resource pool for PSFCH transmission occasion resources by sl-PSFCH-Period-r16. If the number is 0, PSFCH transmission from the UE in the resource pool is disabled. The UE may be provided with k mod N PSFCH PSSCH = 0 if slot t' k SL (0 ≤ k < T' max ) is expected to have PSFCH transmission opportunity resources, where t' k SL is a slot belonging to the resource pool, and T' max is the number of slots belonging to the resource pool within 10240 msec, and N PSFCH PSSCHis provided in sl-PSFCH-Period-r16. The UE may be instructed by upper layers not to transmit a PSFCH in response to a PSSCH reception. When the UE receives a PSSCH from a resource pool and the HARQ Feedback Enable / Disable indicator field included in the associated SCI Format 2-A or SCI Format 2-B has a value of 1, the UE provides HARQ-ACK information via a PSFCH transmission from the resource pool. The UE transmits the PSFCH in a first slot, wherein the first slot includes a PSFCH resource and is a slot after the minimum number of slots provided by sl-MinTimeGapPSFCH-r16 of the resource pool after the last slot of the PSSCH reception.

[0169] The UE selects a set M of PRBs within the resource pool for PSFCH transmission in the PRBs of the resource pool. PSFCH PRB,set is provided by sl-PSFCH-RB-Set-r16. The number of subchannels N for the resource pool provided by sl-NumSubchannel subch and N PSFCH PSSCH For the number of PSSCH slots associated with PSFCH slots less than or equal to M, the UE PRB,set PSFCH Among PRBs, [(i+j·N PSFCH PSSCH )·M PSFCH subch,slot, (i+1+j·N PSFCH PSSCH )·M PSFCH [subch,slot-1] PRB is allocated to slot i and subchannel j among the PSSCH slots linked to the PSFCH slot. Here, M PSFCH subch,slot= M PSFCH PRB,set / (N subch ·N PSFCH PSSCH ), 0 ≤ i < N PSFCH PSSCH , 0 ≤ j < Nsubch , and the assignment starts in ascending order of i and continues in ascending order of j. UE is M PSFCH PRB,set Go N subch ·N PSFCH PSSCH It is expected to be a multiple of .

[0170] The UE determines the number of available PSFCH resources for multiplexing HARQ-ACK information included in the PSFCH transmission. PSFCH PRB,CS = N PSFCH type ·M PSFCH subch,slot·N PSFCH CS is determined by . Here, N PSFCH CS is the number of cyclic shift pairs for the resource pool, and based on instructions from the upper layer,

[0171] - N PSFCH type = 1 and M PSFCH subch,slotPRB is associated with the starting subchannel of the corresponding PSSCH,

[0172] - N PSFCH type = N PSSCH subch Ego and N PSSCH subch ·M PSFCH subch,slotPRB is the N of the corresponding PSSCH PSSCH subch Associated with one or more subchannels among the subchannels.

[0173] PSFCH resources are first N PSFCH type ·M PSFCH subch, slotPRB are indexed in ascending order of PRB index, then N PSFCH CS Among the cyclic shift pairs, they are indexed in ascending order of the cyclic shift pair index.

[0174] The UE, in response to receiving the PSSCH, sends an index of the PSFCH resource for PSFCH transmission (P ID + M ID ) mod R PSFCH PRB,CS is determined by . Here, P ID is the physical layer source ID provided by SCI format 2-A or 2-B for scheduling PSSCH reception, and M ID is the ID of the UE receiving the PSSCH indicated by the upper layer if the UE detects SCI format 2-A with the Cast Type Indicator field value of "01", otherwise M ID is 0.

[0175] UE uses Table 4 to N PSFCH CS Determine the m0 value for calculating the cyclic shift α value from the cyclic shift pair index corresponding to the PSFCH resource index.

[0177] The UE applies one cyclic shift from among the cyclic shift pairs to the sequence used for PSFCH transmission.

[0178] FIG. 9 illustrates resource units for measuring channel busy ratio (CBR) according to an embodiment of the present disclosure. The embodiment of FIG. 9 may be combined with various embodiments of the present disclosure.

[0179] Referring to FIG. 9, CBR may refer to the number of subchannels in which the RSSI (Received Signal Strength Indicator) measurement result value is higher than a preset threshold value when the terminal measures the RSSI per subchannel for a specific period (e.g., 100 ms). Alternatively, CBR may refer to the ratio of subchannels in which the RSSI measurement result value is higher than a preset threshold value among the subchannels in the specific period. For example, in the embodiment of FIG. 9, assuming that the hatched subchannels are subchannels in which the value is higher than a preset threshold value, CBR may refer to the ratio of the hatched subchannels in the 100 ms period. Additionally, the terminal may report the CBR to the base station.

[0180] For example, when PSCCH and PSSCH are multiplexed in the frequency domain, the terminal can perform one CBR measurement for one resource pool. Here, if PSFCH resources are configured or configured in advance, the PSFCH resources can be excluded from the CBR measurement.

[0181] Furthermore, congestion control that considers the priority of traffic (e.g., packets) may be required. For this purpose, for example, the terminal may measure the channel occupancy ratio (CR). Specifically, the terminal may measure the channel occupancy ratio (CBR), and based on the CBR, the terminal may determine the maximum value (CRlimitk) of the channel occupancy ratio (Channel occupancy ratio k, CRk) that traffic corresponding to each priority (e.g., k) may occupy. For example, the terminal may derive the maximum value (CRlimitk) of the channel occupancy for each traffic priority based on a pre-determined table of CBR measurements. For example, for traffic with a relatively high priority, the terminal may derive a relatively large maximum value of the channel occupancy. Thereafter, the terminal may perform congestion control by limiting the sum of the channel occupancies of traffic with a priority k lower than i to a certain value or less. Using this method, traffic with a relatively low priority may be subject to a stronger channel occupancy limit.

[0182] In addition, the terminal can perform SL congestion control by using methods such as adjusting the size of transmission power, dropping packets, deciding whether to retransmit, and adjusting the size of transmission RB (MCS adjustment).

[0183] Table 5 shows an example of SL CBR and SL RSSI.

[0184] SL CBR (SL Channel Busy Ratio) measured in slot n is defined as the fraction of sub-channels of the resource pool for which the SL RSSI measured by the terminal exceeds a (pre-)configured threshold detected over the CBR measurement window [na, n-1], where a is 100 or 100 2 depending on the upper layer parameter sl-TimeWindowSizeCBR. μSlot Same as Applicable RRC_IDLE Intra-frequency, RRC_IDLE Inter-frequency, RRC_CONNECTED Intra-frequency, RRC_CONNECTED Inter-frequency SL RSSI Definition SL RSSI (Sidelink Receiver Signal Strength Indicator) is defined as the linear average of the total received power (in [W]) observed in the configured sub-channels in the OFDM symbols of the slot configured for PSCCH and PSSCH, starting from the second OFDM symbol. For frequency range 1, the reference point for SL RSSI is the antenna connector of the terminal. For frequency range 2, SL RSSI is measured based on the combined signal from the antenna elements corresponding to a given receiver branch. For frequency ranges 1 and 2, if receiver diversity is used by the terminal, the reported SL RSSI value shall not be lower than the corresponding SL RSSI of the individual receiver branches. Applicable RRC_IDLE intra-frequency, RRC_IDLE inter-frequency, RRC_CONNECTED intra-frequency, RRC_CONNECTED inter-frequency

[0185] Referring to Table 5, the slot index may be based on the physical slot index.

[0186] Table 6 shows an example of SL CR (Channel occupancy ratio).

[0187] The Sidelink Channel Occupancy Ratio (SL CR) evaluated at slot n is defined as the total number of sub-channels used for transmission in slot [na, n-1] and admitted in slot [n, n+b] divided by the total number of sub-channels established in the transmission pool over [na, n+b]. Applicable RRC_IDLE intra-frequency, RRC_IDLE inter-frequency, RRC_CONNECTED intra-frequency, RRC_CONNECTED inter-frequency

[0188] Note 1: a is a positive integer and b is 0 or a positive integer. a and b depend on the upper-layer parameter sl-TimeWindowSizeCR, b < (a+b+1) / 2, so a+b+1 = 1000 or 1000·2. u The slots are determined by the UE implementation, and n+b must not exceed the last transmission opportunity of the grant for the current transmission.

[0189] Note 2: SL CR is evaluated for each (re)transmission.

[0190] Note 3: When evaluating SL CR, the UE shall assume that the transmission parameters used in slot n are reused according to the existing grant(s) in slot [n+1, n+b] without dropping packets.

[0191] Note 4: Slot index is based on physical slot index.

[0192] Note 5: SL CR can be calculated by priority level.

[0193] Note 6: A resource is considered approved if it is a member of a selected sidelink grant.

[0194] FIG. 10 illustrates beam management according to one embodiment of the present disclosure. The embodiment of FIG. 10 can be combined with various embodiments of the present disclosure.

[0195] Referring to FIG. 10, beam management may include beam determination, beam measurement, beam reporting, and / or beam sweeping. When forming a beam using multiple antennas, a narrow antenna beam may be transmitted far in a specific direction, but may not be able to widely cover the entire cell at once. In fact, if an antenna beam is formed in one direction, almost no antenna beam may be created in the other direction, resulting in no signal transmission. Therefore, in such cases, a transmitter or receiver may use beam forming to transmit or receive data, respectively. At this time, the transmitter or receiver must continuously update and manage the beams it uses, which may be referred to as beam management.

[0196] For example, the terminal can perform the following motion-based sidelink FR2 (sidelink mmWave frequency-based sidelink communication) operation.

[0197] - Beam sweeping operation: An operation of covering a spatial area using a transmit and / or receive beam for a predetermined time interval in a predetermined manner.

[0198] - Beam measurement operation: An operation to measure the reference signal (RS) transmitted by the counterpart terminal and find the RS whose measurement value is greater than the threshold.

[0199] - Beam selection operation: An operation to select the best beam (reception beam, transmission beam) based on the beam measurement results.

[0200] - Beam reporting operation: An operation to report the selected best beam to the other terminal or base station.

[0201] Meanwhile, in the case of sidelink communication, the terminal may perform transmission and / or reception based on multiple panels and / or beam directions, and in this case, it may be necessary to define a method for managing the beam-related information or settings such as spatial domain transmission and / or reception filters (hereinafter referred to as beam management method). In the present disclosure, sidelink communication may include device-to-device communication, Aircraft-to-Everything (A2X) communication, Vehicle-to-Everything (V2X) communication, etc.

[0202] Conventional sidelink communications have not considered the use of beams with specific directionality. For example, omnidirectional beams were assumed for transmit and / or receive beams, or beams with no specific directionality were considered. Meanwhile, next-generation communication systems are considering the use of beams with specific directionality even in sidelink communications, and methods for managing the transmit and / or receive beams between terminals for this purpose are being discussed.

[0203] Here, the beam management method for the sidelink communication may include a beam pairing method, which is a process of finding a pair of transmission and reception beams between terminals. For example, when a first terminal and a second terminal perform sidelink communication between terminals, the first terminal may transmit resources for beam measurement, and the second terminal may measure reception sensitivity for all or part of a combination of transmission beams and reception beams and then report preferred transmission beam and / or reception beam information to the first terminal. The first terminal may perform communication with the second terminal using the reported transmission beam.

[0204] Here, the beam management method for the sidelink communication may include a multi-beam transmission method, which is a process of transmitting and receiving signals between terminals through one or more transmission beams and / or reception beams. When a first terminal and a second terminal perform sidelink communication, the first terminal may transmit a signal by applying a different transmission beam according to transmission resources, and the second terminal may receive a signal by applying a different reception beam according to transmission resources.

[0205] Here, in the present disclosure, in order to support the beam pairing method and / or the multi-beam transmission method, a resource set may be distinguished according to the beam type during sidelink-based communication between terminals. Then, a method is proposed to support the beam pairing method and / or the multi-beam transmission method by setting one or more of these resource sets as anchor resources to which a common beam or a beam with no specific directionality is applied. Although the proposed methods of the present disclosure are described below with respect to sidelink-based communication between terminals, the proposed methods of the present disclosure can obviously be extended to arbitrary node-to-node communication. Hereinafter, a beam may mean a transmission beam and / or a reception beam. Hereinafter, a first type beam and / or a second type beam in the present disclosure may mean a transmission beam type and / or a reception beam type.

[0206] [Proposal #01] When performing communication between a first terminal and a second terminal, a first resource set to which a first type beam is applied and / or a second resource set to which a second type beam is applied may be agreed upon / set in advance between the terminals. Here, for example, the first type beam may include a common beam whose directionality is not specified. Here, for example, the second type beam may include a dedicated beam whose directionality is specified and / or a common beam whose directionality is not specified.

[0207] For example, when performing sidelink-based communication between a first terminal and a second terminal in a next-generation communication system according to an embodiment of the present disclosure, there are two main methods for starting a beam pairing process. First, beam measurement and reporting processes may be performed using only information previously shared between the terminals prior to beam pairing. Second, beam measurement and reporting processes may be performed using available resources prior to beam pairing in addition to the information previously shared between the terminals prior to beam pairing. Here, considering that sidelink-based communication must be able to support broadcast and / or groupcast transmission in addition to unicast transmission, among the two methods, a method of securing available resources between the terminals prior to beam pairing may be more preferable. For example, when performing unicast transmission between terminals, a transmission beam and / or a reception beam whose directionality is specified may be applied by performing beam pairing, and when performing broadcast and / or groupcast transmission between terminals, a transmission beam and / or a reception beam whose directionality is not specified may be applied without performing beam pairing.

[0208] Therefore, in the present disclosure, when performing communication between a first terminal and a second terminal, a first resource set to which a first type beam is applied and / or a second resource set to which a second type beam is applied may be agreed upon / established in advance between the terminals. For example, the first type beam may refer to a common beam whose directionality is not specified, and the second type beam may include the common beam and / or a dedicated beam whose directionality is specified. Here, since the first resource set does not have a constraint that causes the terminal to form a beam in a specific direction, it can support communication between the first terminal and the second terminal even before beam pairing and / or when beam pairing is unstable. Therefore, the first resource set can serve as an anchor that ensures minimum connectivity for sidelink communication.

[0209] FIG. 11 illustrates a first resource set to which a first type beam is applied and a second resource set to which a second type beam is applied, according to an embodiment of the present disclosure. The embodiment of FIG. 11 may be combined with various embodiments of the present disclosure.

[0210] The above [Proposal #01] can be applied in combination with other proposed methods(s) to the extent that the proposed actions do not conflict.

[0211] [Proposal #01-01] When performing communication between a first terminal and a second terminal, when a first resource set to which a first type beam is applied and / or a second resource set to which a second type beam is applied are agreed upon / set in advance between the terminals, the first terminal may transmit a second control signal within the first resource set to reserve and / or indicate beam measurement resources within the second resource set, and the second terminal may perform beam measurement using the beam measurement resources. Here, for example, the first type beam may include a common beam whose directionality is not specified. Here, for example, the second type beam may include a dedicated beam whose directionality is specified and / or a common beam whose directionality is not specified. Here, for example, the second control signal may indicate beam identifier information and / or beam-related information corresponding to beam measurement resources transmitted within the second resource set. Here, for example, the second control signal may be a primary SCI (sidelink control information) and / or a secondary SCI and / or a MAC CE (control element).

[0212] For example, when performing sidelink-based communication between a first terminal and a second terminal in a next-generation communication system according to an embodiment of the present disclosure, a process of measuring and comparing reception sensitivity for each combination of transmission beams and reception beams must be performed in advance in order to select a pair of transmission beams and / or reception beams. In order to measure reception sensitivity for a combination of transmission beams and reception beams, the reception terminal must be able to know the location of a resource to which a measurement resource corresponding to a specific transmission beam and / or transmission beam identifier is transmitted, so as to measure the reception sensitivity for a specific transmission beam and / or transmission beam identifier. For example, when the reception terminal wants to measure reception sensitivity for each combination between a specific transmission beam and M reception beams, the reception terminal must be able to know the transmission locations of the M measurement resources to which the specific transmission beam is applied. Here, when the initial beam pairing process is supported, the transmission locations of the beam measurement resources must be able to be transmitted to the reception terminal before beam pairing.

[0213] Therefore, in the present disclosure, when performing communication between a first terminal and a second terminal, a first resource set to which a first type beam is applied and / or a second resource set to which a second type beam is applied can be agreed upon / set in advance between the terminals, and the first terminal can transmit a second control signal within the first resource set to reserve and / or indicate beam measurement resources within the second resource set. For example, the first type beam may mean a common beam whose directionality is not specified, and the second type beam may include the common beam and / or a dedicated beam whose directionality is specified. Here, since the first resource set does not have a constraint that allows the terminal to form a beam in a specific direction, it can support communication between the first terminal and the second terminal even before beam pairing. Therefore, the first resource set can serve as an anchor that notifies beam measurement resources in the second resource set whose beam direction can be specified. According to the proposed method of the present disclosure, there is an advantage in that the transmission location of beam measurement resources for initial beam pairing can be stably transmitted prior to beam pairing by informing of beam measurement resource transmission in a resource set where beam directionality can be specified in a resource set where beam directionality is not specified. In addition, since the first resource set allows sidelink communication without a beam pairing process, it can be utilized as a stable anchor resource that supports data transmission where directionality is not specified in addition to reservation and / or indication for beam measurement resources.

[0214] The above [Proposal #01-01] can be applied in combination with other proposed methods(s) to the extent that the proposed actions do not conflict.

[0215] [Proposal #01-02] When performing communication between a first terminal and a second terminal, when a first resource set to which a first type beam is applied and / or a second resource set to which a second type beam is applied are agreed upon / set in advance between the terminals, the first terminal may transmit a second control signal within the first resource set to reserve and / or instruct a beam measurement resource within the second resource set, the second terminal may perform beam measurement using the beam measurement resource and then report the beam measurement result, and the first terminal may apply a reception beam corresponding to the transmission beam applied to the first resource when receiving the beam measurement result. Here, for example, the first type beam may include a common beam whose directionality is not specified. Here, for example, the second type beam may include a dedicated beam whose directionality is specified and / or a common beam whose directionality is not specified. Here, for example, the second terminal can report the beam measurement result with the resources in the first resource set and / or the resources in the second resource set. Here, for example, the transmission beam applied by the second terminal when reporting the beam measurement result may be the transmission beam corresponding to the reception beam applied when receiving the second control signal, or may be the transmission beam corresponding to the optimal transmission beam and / or reception beam searched for with the beam measurement resource. Here, for example, the beam measurement result report may include whether beam pairing succeeded / failed. For example, if there is no pair of transmission beams and reception beams whose reception sensitivity is higher than a reference value, it may be reported that beam pairing failed. Here, for example, the second control signal may indicate a beam identifier and / or beam-related information corresponding to the beam measurement resource transmitted in the second resource set. Here, for example, the second control signal may be a primary SCI (sidelink control information) and / or a secondary SCI and / or a MAC CE (control element).Here, for example, reservation information for transmission resources within the second resource set may or may not be transmitted depending on channel congestion, as expressed by indicators such as Channel Busy Ratio (CBR) and / or Channel Occupancy Ratio (CR). For example, if the CBR and / or CR are high, transmitting resource reservation information may be omitted, as it may be meaningless.

[0216] For example, when performing sidelink-based communication between a first terminal and a second terminal in a next-generation communication system according to an embodiment of the present disclosure, a process of measuring and comparing reception sensitivity for each combination of transmission beams and reception beams must be performed in advance in order to select a pair of transmission beams and / or reception beams. In order to measure reception sensitivity for a combination of transmission beams and reception beams, the receiving terminal must be able to know the location of a resource to which a measurement resource corresponding to a specific transmission beam and / or transmission beam identifier is transmitted, so that the reception sensitivity for the specific transmission beam and / or transmission beam identifier can be measured. Here, transmission of a beam measurement resource requiring transmission beam and / or reception beam configuration in a specific direction can be instructed by utilizing available resources prior to beam pairing. For example, as an embodiment according to the proposed method(s) of the present disclosure, a first resource set to which a first type beam is applied and / or a second resource set to which a second type beam is applied may be agreed upon and / or set in advance between terminals, and the first terminal may transmit a second control signal within the first resource set to reserve and / or indicate beam measurement resources within the second resource set. For example, the first type beam may mean a common beam whose directionality is not specified, and the second type beam may include the common beam and / or a dedicated beam whose directionality is specified. Here, for the beam pairing process, the second terminal may report the beam measurement result utilizing the beam measurement resource to the first terminal. Here, since the first terminal does not know which transmission beam and reception beam pair the second terminal selected as the optimal beam pair during the beam measurement process, the first terminal may assume a reception beam corresponding to the transmission beam transmitted via the second control signal upon receiving the beam measurement result reported by the second terminal. For example, the second terminal may report beam measurement results to a resource within the first resource set where beam directionality is not specified.If the first terminal wants to apply a reception beam corresponding to one of the transmission beams of the beam measurement resource when receiving the beam measurement result reported by the second terminal, the reception resource must be set as a dedicated resource for the second terminal because only reception with a specific directionality is allowed, which may result in significant restrictions on resource utilization. According to the proposed method of the present disclosure, there is an advantage of allowing the receiving terminal to report on the beam measurement result, while alleviating the reception beam restrictions in the reporting resource.

[0217] FIG. 12 illustrates beam measurement and / or beam reporting based on a first resource set and / or a second resource set, according to an embodiment of the present disclosure. The embodiment of FIG. 12 may be combined with various embodiments of the present disclosure.

[0218] The above [Proposal #01-02] can be applied in combination with other proposed methods(s) to the extent that the proposed actions do not conflict.

[0219] [Proposal #01-03] When performing communication between a first terminal and a second terminal, when a first resource set to which a first type beam is applied and / or a second resource set to which a second type beam is applied are agreed upon / set in advance between the terminals, the terminal may configure a first sensing resource set with resources in the first resource set, and the terminal may utilize resource reservation information indicated in control signal(s) in the first sensing resource set and / or measured reception sensitivity in the first sensing resource set when selecting a transmission resource in the first resource set and / or selecting a transmission resource in the second resource set. Here, for example, the first type beam may include a common beam whose directionality is not specified. Here, for example, the second type beam may include a dedicated beam whose directionality is specified and / or a common beam whose directionality is not specified. Here, for example, the terminal may derive the expected reception sensitivity by reflecting the transmission beam gain and / or reception beam gain to the measured reception sensitivity within the first sensing resource set when predicting the reception sensitivity for the reserved resources within the second resource set. Here, for example, the transmission beam gain and / or reception beam gain information may be agreed upon and / or set in advance between the terminals or may be transmitted via a control signal.

[0220] For example, when performing sidelink-based communication between a first terminal and a second terminal in a next-generation communication system according to an embodiment of the present disclosure, the terminal may perform resource selection based on the sensing result. For example, the terminal may define a candidate resource set for resource reservation and / or allocation, and the terminal may configure a sensing resource set that precedes the candidate resource set. The terminal may detect control signals (e.g., SCI) transmitted by other terminals in the sensing resource set to recognize reserved resources, and the terminal may measure reception sensitivity (e.g., reference signals received power (RSRP)) using reference signals in the sensing resource set. In addition, the terminal may predict reception sensitivity due to the reserved resources based on the measured reception sensitivity, and the terminal may select a transmission resource from the remaining resources, excluding resources whose related reception sensitivity is higher than a certain threshold. Meanwhile, in the case where beam pairing for sidelink-based communication is supported in the next-generation communication system according to an embodiment of the present disclosure, when sensing-based resource selection is applied to resources where the transmission beam and / or reception beam have directionality, a problem of misjudging the influence of interference from other terminals, such as the hidden node problem, may occur. For example, suppose that a first terminal performs sensing in a specific beam direction, selects a resource that it feels has less interference, and then transmits to a second terminal in the beam direction. Here, signals from other terminals that were not observed during sensing in the specific beam direction may have existed, and from the receiving perspective of the second terminal, interference from the other terminals may have a significant effect.

[0221] Therefore, in the present disclosure, when performing communication between a first terminal and a second terminal, when a first resource set to which a first type beam is applied and / or a second resource set to which a second type beam is applied are agreed upon / set in advance between the terminals, a first sensing resource set can be configured with resources within the first resource set, and when transmitting within the first resource set and / or transmitting within the second resources, resource reservation information indicated in control signal(s) within the first sensing resource set and / or measured reception sensitivity within the first sensing resource set can be utilized. For example, the first type beam can mean a common beam whose directionality is not specified, and the second type beam can include the common beam and / or a dedicated beam whose directionality is specified. Here, since the first resource set does not have a restriction that causes the terminal to form a beam in a specific direction, sensing in all directions is possible and a hidden node problem depending on beam directionality can be alleviated. According to the proposed method of the present disclosure, when performing transmission resource selection with a specified beam directionality, there is an advantage in that a set of sensing resources composed of resources with an unspecified beam directionality is utilized, thereby alleviating problems such as hidden nodes occurring between transmission resources with a specified beam directionality.

[0222] FIG. 13 illustrates sensing based on a first set of resources, according to an embodiment of the present disclosure. The embodiment of FIG. 13 may be combined with various embodiments of the present disclosure.

[0223] The above [Proposal #01-03] can be applied in combination with other proposed methods(s) to the extent that the proposed actions do not conflict.

[0224] [Proposal #01-04] When performing communication between a first terminal and a second terminal, when a first resource set to which a first type beam is applied and / or a second resource set to which a second type beam is applied are agreed upon / set in advance between the terminals, the terminal may configure a second sensing resource set with resources in the second resource set, and when selecting a (transmission) resource in the second resource set, the terminal may utilize resource reservation information indicated in control signal(s) in the second sensing resource set and / or measured reception sensitivity in the second sensing resource set. Here, for example, the first type beam may include a common beam whose directionality is not specified. Here, for example, the second type beam may include a dedicated beam whose directionality is specified and / or a common beam whose directionality is not specified. Here, for example, the terminal may utilize only a sensing result detected in a reception beam direction corresponding to a transmission beam direction to be applied when reserving resources. For example, only the sensed results can be utilized by applying a common beam.

[0225] For example, when performing sidelink-based communication between a first terminal and a second terminal in a next-generation communication system according to an embodiment of the present disclosure, the terminal may perform resource selection based on a sensing result. For example, in an embodiment according to the proposed method(s) of the present disclosure, a first resource set to which a first type beam is applied and / or a second resource set to which a second type beam is applied may be agreed upon / established in advance between the terminals, a first sensing resource set may be configured with resources in the first resource set, and when transmitting within the first resource set and / or transmitting within the second resource, resource reservation information indicated in control signal(s) in the first sensing resource set and / or measured reception sensitivity in the first sensing resource set may be utilized. For example, the first type beam may mean a common beam whose directionality is not specified, and the second type beam may include the common beam and / or a dedicated beam whose directionality is specified. Here, the first sensing resource set allows for omnidirectional sensing, which may mitigate issues such as hidden node problems. Meanwhile, the terminal can detect control information transmitted by other nodes within the second resource set. While this information may have limitations in that it can only be received in a specific beam direction, if detected information exists, utilizing it as additional sensing information can improve sensing accuracy.

[0226] Therefore, in the present disclosure, when performing communication between a first terminal and a second terminal, when a first resource set to which a first type beam is applied and / or a second resource set to which a second type beam is applied are agreed upon / set in advance between the terminals, the terminal may configure a second sensing resource set with resources within the second resource set, and when selecting a (transmission) resource within the second resource set, the terminal may utilize resource reservation information indicated by control signal(s) within the second sensing resource set and / or measured reception sensitivity within the second sensing resource set. For example, the terminal may utilize resource reservation information indicated by control signal(s) within the first sensing resource set and / or measured reception sensitivity within the first sensing resource set as primary information, and the terminal may utilize resource reservation information indicated by control signal(s) within the second sensing resource set and / or measured reception sensitivity within the second sensing resource set as secondary information. According to the proposed method of the present disclosure, there is an advantage in that accurate sensing results can be obtained by enabling the terminal to utilize sensing results within both the first resource set and the second resource set when selecting sensing-based resources.

[0227] The above [Proposal #01-04] can be applied in combination with other proposed methods(s) to the extent that the proposed actions do not conflict.

[0228] [Proposal #01-05] When performing communication between a first terminal and a second terminal, when a first resource set to which a first type beam is applied and / or a second resource set to which a second type beam is applied are agreed upon / set in advance between the terminals, the terminal may transmit a first control signal within the first resource set to reserve (transmission) resources within the first resource set, and the terminal may transmit a second control signal (distinct from the first control signal) within the first resource set to reserve (transmission) resources within the second resource set. Here, for example, the first type beam may include a common beam whose directionality is not specified. Here, for example, the second type beam may include a dedicated beam whose directionality is specified and / or a common beam whose directionality is not specified. Here, for example, the first control signal may be a primary sidelink control information (SCI), and the second control signal may be a secondary SCI and / or a MAC control element (CE). Here, for example, the second control signal may also indicate beam identifier information corresponding to a (transmission) resource reserved within the second resource set.

[0229] For example, when performing sidelink-based communication between a first terminal and a second terminal in a next-generation communication system according to an embodiment of the present disclosure, the terminal may perform resource selection based on the sensing result. For example, the terminal may define a candidate resource set for resource reservation and / or allocation, and the terminal may configure a sensing resource set that precedes the candidate resource set. The terminal may detect control signals (e.g., SCI) transmitted by other terminals in the sensing resource set to recognize reserved resources, and the terminal may measure reception sensitivity (e.g., reference signals received power (RSRP)) using reference signals in the sensing resource set. In addition, the terminal may predict reception sensitivity due to the reserved resources based on the measured reception sensitivity, and the terminal may select a transmission resource from the remaining resources, excluding resources whose related reception sensitivity is higher than a certain threshold. Here, as an embodiment according to the proposed method(s) of the present disclosure, it is assumed that a first resource set to which a first type beam is applied and / or a second resource set to which a second type beam is applied are agreed upon / established in advance between terminals, the terminal configures a first sensing resource set with resources in the first resource set, and when transmitting within the first resource set and / or transmitting within the second resource, resource reservation information indicated in control signal(s) in the first sensing resource set and / or measured reception sensitivity in the first sensing resource set are utilized. For example, the first type beam may mean a common beam whose directionality is not specified, and the second type beam may include the common beam and / or a dedicated beam whose directionality is specified. In this case, transmission resources reserved within the first resource set and / or the second resource set must be indicated within the first sensing resource set.Here, since the first sensing resource set is composed of resources within the first resource set, reservation information for the resources to be transmitted in the future can be indicated via a control signal within the first resource set. Here, the reservation information for the resources to be transmitted within the second resource set must include information related to a transmission beam and / or a reception beam, and needs to be distinguished from the reservation information for the resources to be transmitted within the first resource set, where the directionality of the beam is not specified.

[0230] Accordingly, in the present disclosure, when performing communication between a first terminal and a second terminal, when a first resource set to which a first type beam is applied and / or a second resource set to which a second type beam is applied are agreed upon / set in advance between the terminals, the terminal may transmit a first control signal within the first resource set to reserve transmission resources within the first resource set, and the terminal may transmit a second control signal (distinct from the first control signal) within the first resource set to reserve transmission resources within the second resource set. For example, reservation information for transmission resources may be transmitted as a control signal within the first resource set, but resources to be transmitted within the first resource set may be reserved and / or indicated by a primary SCI, and resources to be transmitted within the second resource set may be reserved and / or indicated by a secondary SCI and / or MAC CE. According to the proposed method of the present disclosure, there is an advantage in that control signals suitable for resource reservation and / or instruction within each set can be separately configured for the first and second resource sets, thereby efficiently transmitting resource reservation information.

[0231] FIG. 14 illustrates a method for a terminal to reserve resources within a second resource set by transmitting a control signal within a first resource set, according to one embodiment of the present disclosure. The embodiment of FIG. 14 may be combined with various embodiments of the present disclosure.

[0232] The above [Proposal #01-05] can be applied in combination with other proposed methods(s) to the extent that the proposed actions do not conflict.

[0233] [Proposal #01-06] When performing communication between a first terminal and a second terminal, when a first resource set to which a first type beam is applied and / or a second resource set to which a second type beam is applied are agreed upon / set in advance between the terminals, the terminal may transmit a third control signal within the second resource set to reserve (transmission) resources within the second resource set. Here, for example, the first type beam may include a common beam whose directionality is not specified. Here, for example, the second type beam may include a dedicated beam whose directionality is specified and / or a common beam whose directionality is not specified. Here, for example, the third control signal may be a primary SCI (sidelink control information) and / or a secondary SCI and / or a MAC CE (control element). Here, for example, the third control signal may also indicate beam identifier information corresponding to the (transmission) resources reserved within the second resource set.

[0234] For example, when performing sidelink-based communication between a first terminal and a second terminal in a next-generation communication system according to an embodiment of the present disclosure, the terminal may perform resource selection based on a sensing result. For example, in an embodiment according to the proposed method(s) of the present disclosure, when a first resource set to which a first type beam is applied and / or a second resource set to which a second type beam is applied are agreed upon and / or set between the terminals in advance, the terminal may configure a second sensing resource set with resources in the second resource set, and when selecting a (transmission) resource in the second resource set, the terminal may utilize resource reservation information indicated in control signal(s) in the second sensing resource set and / or measured reception sensitivity in the second sensing resource set. For example, the first type beam may mean a common beam whose directionality is not specified, and the second type beam may include the common beam and / or a dedicated beam whose directionality is specified. Here, since the second sensing resource set is composed of resources within the second resource set, reservation information for resources to be transmitted in the future within the second resource set can be indicated via a control signal within the second resource set. Specifically, the control information within the first resource set can reserve resources within the first and second resource sets, but the control information within the second resource set can only reserve resources within the second resource set. This is because the first resource set is a resource set in which a first type beam is assumed and a plurality of terminals are expected to monitor, whereas the second resource set is a resource set in which a second type beam is assumed and only some terminals are expected to monitor. When the terminal detects reserved information for the second resource set, the terminal can utilize the control signal transmitted within the first resource set and / or the control signal transmitted within the second resource set.According to the proposed method of the present disclosure, primary resource reservation for the first and second resource sets can be performed using a control signal within the first resource set, and an operation can be performed to re-inform resource reservation information within the second resource set using a control signal within the second resource set. This has the advantage of increasing the reliability of reservation information transmission by providing resource reservation information through various paths.

[0235] The above [Proposal #01-06] can be applied in combination with other proposed methods(s) to the extent that the proposed actions do not conflict.

[0236] [Proposal #01-07] When performing communication between a first terminal and a second terminal, when a first resource set to which a first type beam is applied and / or a second resource set to which a second type beam is applied are agreed upon / set in advance between the terminals, when the terminals configure a candidate resource set for resource reservation and / or selection, the first candidate resource set composed of resources in the first resource set and the second candidate resource set composed of resources in the second resource set can be configured separately. Here, for example, the first type beam can include a common beam whose directionality is not specified. Here, for example, the second type beam can include a dedicated beam whose directionality is specified and / or a common beam whose directionality is not specified.

[0237] For example, when performing sidelink-based communication between a first terminal and a second terminal in a next-generation communication system according to an embodiment of the present disclosure, resource selection based on sensing results may be performed. For example, the terminal may define a candidate resource set for resource reservation and / or allocation, and the terminal may configure a sensing resource set that is ahead of the candidate resource set. The terminal may detect control signals (e.g., SCI) transmitted by other terminals in the sensing resource set to recognize reserved resources, and may measure reception sensitivity (e.g., reference signals received power (RSRP)) using reference signals within the sensing resource set. In addition, the terminal may predict reception sensitivity due to the reserved resources based on the measured reception sensitivity, and the terminal may select a transmission resource from the remaining resources, excluding resources with a related reception sensitivity above a certain threshold. Here, as an embodiment according to the proposed method(s) of the present disclosure, when a first resource set to which a first type beam is applied and / or a second resource set to which a second type beam is applied are agreed upon / set in advance between terminals, it may be desirable for the candidate resource sets to be distinguished by each beam type. For example, the first type beam may mean a common beam whose directionality is not specified, and the second type beam may include the common beam and / or a dedicated beam whose directionality is specified. For example, the terminal may configure a first sensing resource set composed of resources in the first resource set for the first candidate resource set composed of resources in the first resource set, and the terminal may perform sensing-based resource reservation and / or selection by utilizing this. Here, within the first sensing resource set, resource reservation information within the first resource set may be indicated by a primary SCI that conventional terminals can demodulate, and thus, coexistence of conventional terminals that do not support the second type beam may be permitted within the first resource set.For example, conventional terminals can operate as if the first resource set is given as a resource pool. In addition, for example, the terminal can configure a first sensing resource set composed of resources in the first resource set for a second candidate resource set composed of resources in the second resource set, and the terminal can perform sensing-based resource reservation and / or selection by utilizing this. Here, resource reservation information in the second resource set within the first sensing resource set may be indicated by a secondary SCI or MAC CE that conventional terminals cannot demodulate, and therefore coexistence of conventional terminals that do not support the second type beam within the second resource set may be difficult. According to the proposed method of the present disclosure, there is an advantage in that independent sensing and / or resource selection methods can be applied by distinguishing candidate resource sets by beam type for transmission resource sets to which different beam types are applied.

[0238] The above [Proposal #01-07] can be applied in combination with other proposed methods(s) to the extent that the proposed actions do not conflict.

[0239] [Proposal #01-08] When performing communication between a first terminal and a second terminal, when a first resource set to which a first type beam is applied and / or a second resource set to which a second type beam is applied are agreed upon / set in advance between the terminals, when the terminals configure a preferred resource set and / or a non-preferred resource set for resource reservation and / or selection, the first preferred / non-preferred resource set composed of resources in the first resource set and the second preferred / non-preferred resource set composed of resources in the second resource set can be configured separately. Here, for example, the first type beam can include a common beam whose directionality is not specified. Here, for example, the second type beam can include a dedicated beam whose directionality is specified and / or a common beam whose directionality is not specified. Here, for example, the transmitting terminal can select a final (transmission) resource by utilizing the preferred resource set and / or the non-preferred resource set.

[0240] For example, when performing sidelink-based communication between a first terminal and a second terminal in a next-generation communication system according to an embodiment of the present disclosure, the receiving terminal may report a preferred resource set and / or a non-preferred resource set from the receiver's perspective to the transmitting terminal. Here, as an embodiment according to the proposed method(s) of the present disclosure, when a first resource set to which a first type beam is applied and / or a second resource set to which a second type beam is applied are agreed upon / set in advance between the terminals, it may be desirable for the preferred / non-preferred resource set to be distinguished for each beam type. For example, the first type beam may mean a common beam whose directionality is not specified, and the second type beam may include the common beam and / or a dedicated beam whose directionality is specified. For example, the receiving terminal may provide the transmitting terminal with a first preferred / non-preferred resource set composed of resources within the first resource set and a second preferred / non-preferred resource set composed of resources within the second resource set. Here, the transmitting terminal can utilize the first preferred / non-preferred resource set when selecting resources within the first resource set, and the transmitting terminal can utilize the second preferred / non-preferred resource set when selecting resources within the second resource set. According to the proposed method of the present disclosure, for resource sets to which different beam types are applied, there is an advantage in that independent sensing and / or resource selection methods can be applied by distinguishing the preferred / non-preferred resource sets by beam type.

[0241] The above [Proposal #01-08] can be applied in combination with other proposed methods(s) to the extent that the proposed actions do not conflict.

[0242] [Proposal #01-09] When performing communication between a first terminal and a second terminal, when a first resource set to which a first type beam is applied and / or a second resource set to which a second type beam is applied are agreed upon / set in advance between the terminals, the first type beam and the second type beam may be defined to distinguish reception beam types that may be used in the first resource set and the second resource set, respectively. Here, for example, the first type beam may mean a common reception beam with no specified directionality or a reception beam that may be used when not performing beam pairing-based communication. Here, for example, the second type beam may mean a dedicated reception beam with specified directionality or a reception beam that may be used when performing beam pairing-based communication. Here, for example, the transmission beam that may be applied to the first resource set and / or the second resource set may not be restricted.

[0243] For example, when performing sidelink-based communication between a first terminal and a second terminal in a next-generation communication system according to an embodiment of the present disclosure, resources for broadcast transmission and / or group cast transmission between the terminals may be supported. For example, a resource set for terminal-to-terminal communication may be divided into a first resource set and a second resource set, and a first type beam and a second type beam may be allowed in each resource set. Here, the first type beam and the second type beam may be restrictions on the type of reception beam. For example, the first type beam may mean a common reception beam with no specific directionality or a reception beam that can be used when not performing beam pairing-based communication. For example, the second type beam may mean a dedicated reception beam with specific directionality or a reception beam that can be used when performing beam pairing-based communication. For example, a transmitting terminal may transmit broadcast data and / or group cast data through the first resource set, and a receiving terminal may attempt to receive data in an omni-directional beam in the first resource set. For example, a transmitting terminal may transmit unicast data through the second resource set, and a receiving terminal may attempt to receive data in an omni-directional beam and / or a directional beam in the second resource set.

[0244] Here, as a modification of [Proposal #01-09], when performing communication between a first terminal and a second terminal, when a first resource set to which a first type beam is applied and / or a second resource set to which a second type beam is applied are agreed upon / set in advance between the terminals, a method may also be considered in which the first type beam and the second type beam are defined to distinguish transmission beam types that can be used in the first resource set and the second resource set, respectively. Here, the reception beam that can be applied to the first resource set and / or the second resource set may not be restricted.

[0245] The above [Proposal #01-09] can be applied in combination with other proposed methods(s) to the extent that the proposed actions do not conflict.

[0246] [Proposal #01-10] When performing communication between a first terminal and a second terminal, when a first resource set to which a first type beam is applied and / or a second resource set to which a second type beam is applied are agreed upon / set in advance between the terminals, the terminal may define a candidate resource set for transmission resource selection with resources in the first resource set and the second resource set, and the terminal may exclude resources in the candidate resource set whose reception sensitivity of reserved resource transmission is greater than or equal to a threshold. At this time, the threshold may be applied differently to the first resource set and the second resource set. Here, for example, the first type beam may mean a common beam with no specified directionality or a beam that can be used when not performing beam pairing-based communication. Here, for example, the second type beam may mean a dedicated beam with specified directionality or a beam that can be used when performing beam pairing-based communication.

[0247] For example, when performing sidelink-based communication between a first terminal and a second terminal in a next-generation communication system according to an embodiment of the present disclosure, the terminal may perform resource selection based on a sensing result. For example, the terminal may define a candidate resource set for transmission resource selection, and the terminal may configure a sensing resource set that precedes the candidate resource set. The terminal may detect control signals (e.g., SCI) transmitted by other terminals in the sensing resource set to recognize reserved resources, and the terminal may measure reception sensitivity (e.g., reference signals received power (RSRP)) using reference signals in the sensing resource set. In addition, the terminal may predict reception sensitivity due to the reserved resources based on the measured reception sensitivity, and the terminal may select a transmission resource from the remaining resources, excluding resources with a related reception sensitivity higher than a certain threshold. Here, when there are a first resource set to which a first type beam is applied and a second resource set to which a second type beam is applied according to an embodiment of the present disclosure, the candidate resource set for selecting the transmission resource may include both resources in the first resource set and resources in the second resource set. Here, a reference value for comparing the reception sensitivity for the reserved resources may be applied differently to the resources in the first resource set and the resources in the second resource set. For example, when the first type beam is an omnidirectional beam, the beam gain may be small, so the reference value may be set high. For example, when the second type beam is a directional beam, the beam gain may be large, so the reference value may be set low. According to the proposed method of the present disclosure, there is an advantage in that resource selection that compensates for the difference due to the beam gain is possible by setting a reference value for resource selection for each beam type.

[0248] The above [Proposal #01-10] can be applied in combination with other proposed methods(s) to the extent that the proposed actions do not conflict.

[0249] [Proposal #01-11] When performing communication between a first terminal and a second terminal, when a first resource set to which a first type beam is applied and / or a second resource set to which a second type beam is applied are agreed upon / set in advance between the terminals, the terminal can define a candidate resource set for selecting transmission resources with resources in the first resource set and the second resource set, and the terminal can exclude some resources from the candidate resource set according to conditions. At this time, if the remaining resources are below a certain ratio, the terminal can restore the excluded resources. When restoring, a specific beam type resource can be given priority. Here, for example, the first type beam can mean a common beam with no specified directionality or a beam that can be used when not performing beam pairing-based communication. Here, for example, the second type beam can mean a dedicated beam with specified directionality or a beam that can be used when performing beam pairing-based communication. Here, for example, the specific beam type given priority can be the first type beam or the second type beam.

[0250] For example, when performing sidelink-based communication between a first terminal and a second terminal in a next-generation communication system according to an embodiment of the present disclosure, the terminal may perform resource selection based on channel sensing. For example, the terminal may define a candidate resource set for transmission resource selection, and the terminal may configure a sensing resource set that precedes the candidate resource set. The terminal may detect control signals (e.g., SCI) transmitted by other terminals in the sensing resource set to recognize reserved resources, and the terminal may measure reception sensitivity (e.g., reference signals received power (RSRP)) using reference signals within the sensing resource set. In addition, the terminal may predict reception sensitivity due to reserved resources based on the measured reception sensitivity, and the terminal may select transmission resources from the remaining resources, excluding resources with a related reception sensitivity greater than a predetermined threshold. Here, the terminal may restore the excluded resources if the remaining resources are below a predetermined ratio. Here, in the case where resources with distinct beam types exist as in the embodiment of the present disclosure, the terminal may prioritize the recovery of resources of a specific beam type. For example, if the first type beam is an omnidirectional beam, the interference size from other terminals may be excessively measured for resources within the first resource set to which the first type beam is applied. For example, if a receiving terminal receives with a directional beam, signals coming in from directions other than the corresponding direction may not act as interference. Therefore, when the terminal recovers resources excluded from the resource selection process, it may prioritize the recovery of resources corresponding to the first type beam over resources corresponding to the second type beam. According to the proposed method of the present disclosure, there is an advantage in that resources that are expected to have less interference can be prioritized and included in candidate resources.

[0251] The above [Proposal #01-11] can be applied in combination with other proposed methods(s) to the extent that the proposed actions do not conflict.

[0252] [Proposal #02] When performing communication between a first terminal and a second terminal, the terminal may perform channel sensing for selecting and / or allocating transmission resources from a second resource pool in the first resource pool. Here, for example, the first resource pool and the second resource pool may be composed of distinct resources. For example, time-domain and / or frequency-domain resources may be distinct. For example, bandwidth part (BWP) and / or carrier may be distinct.

[0253] For example, when performing sidelink-based communication between a first terminal and a second terminal in a next-generation communication system according to an embodiment of the present disclosure, a first resource pool and a second resource pool that are distinct from each other may be utilized. Here, the resource pool may mean a set of resources available for sidelink-based communication. For example, the resource pool may include information on available slots and information on available resource blocks (RBs) within a sidelink bandwidth part (BWP). Here, the terminal may be configured with one or more resource pools for sidelink communication. For example, the terminal may be configured with a first resource pool and a second resource pool. Here, the first resource pool may be a resource pool that does not utilize a directional beam, and the second resource pool may be a resource pool that utilizes a directional beam. For example, the first resource pool may be defined in FR1 (frequency range 1), and the second resource pool may be defined in FR2. Here, when the terminal performs channel sensing for selecting and / or allocating transmission resources within the second resource pool, the channel sensing may be performed within the first resource pool. For example, channel sensing may be performed assuming an omnidirectional reception beam within the first resource pool, and candidate transmission resources within the second resource pool may be selected based on the results. According to the proposed method of the present disclosure, there is an advantage in solving the channel sensing problem by utilizing the channel sensing results from a resource pool where channel sensing is effective for selecting transmission resources in a resource pool with limited channel sensing.

[0254] The above [Proposal #02] can be applied in combination with other proposed methods(s) to the extent that the proposed actions do not conflict.

[0255] [Proposal #03] When performing communication between a first terminal and a second terminal, repeated transmission may be performed for control signals and / or data transmitted based on a transmission method and / or transmission resources that have been previously promised / set, and the terminal may aggregate the reception results for the repeated transmissions and utilize them for channel sensing. Here, for example, the transmission method that has been previously promised / set may refer to a beam type. For example, in the case of transmission in an omnidirectional beam, repeated transmission may be performed to compensate for a small antenna gain, and in the case of transmission in a directional beam, repeated transmission may not be performed.

[0256] For example, when performing sidelink-based communication between a first terminal and a second terminal in a next-generation communication system according to an embodiment of the present disclosure, resource selection based on sensing results may be performed in the sidelink-based communication. For example, the terminal may define a candidate resource set for resource reservation and / or allocation, and the terminal may configure a sensing resource set that precedes the candidate resource set. The terminal may detect control signals (e.g., SCI) transmitted by other terminals in the sensing resource set to recognize reserved resources, and the terminal may measure reception sensitivity (e.g., reference signals received power (RSRP)) using reference signals within the sensing resource set. In addition, the terminal may predict reception sensitivity due to the reserved resources based on the measured reception sensitivity, and the terminal may select a transmission resource from the remaining resources, excluding resources whose related reception sensitivity is above a certain threshold. Here, control signals and / or data may be repeatedly transmitted depending on the use of a specific transmission method and / or specific transmission resources. For example, when performing side-link-based communication in FR2, control signals and / or data transmitted in an omni-directional beam may be repeatedly transmitted to compensate for small antenna gain, and control signals and / or data transmitted in a directional beam may not be repeatedly transmitted. Here, sensing for resources that are repeatedly transmitted may be reflected by aggregating the reception results for the repeated transmissions. For example, after combining the reception signals for the repeated transmissions, detection and / or RSRP measurement for the control signal may be performed. Here, the phase of the reception signals may be compensated for through a channel estimation process, and then the repeated reception signals may be combined. According to the proposed method of the present disclosure, there is an advantage in that channel sensing results that reflect the effect of repeated transmission can be expected for resources that are repeatedly transmitted.For example, if a control signal is detected for each slot in the conventional manner for repeatedly transmitted resources and then used for channel sensing, there is a limitation in that the noise mitigation benefits due to repeated transmission cannot be fully enjoyed.

[0257] The above [Proposal #03] can be applied in combination with other proposed methods(s) to the extent that the proposed actions do not conflict.

[0258] In an embodiment of the present disclosure, spatial setting information for sidelink transmission may be changed / managed / configured / instructed differently or independently by recast type and / or by unicast session and / or by receiver for sidelink transmission and / or by SL channel type and / or by (transmitting and / or receiving) resource pool and / or by mobility-related information (e.g., speed, velocity, direction, acceleration, position, height, etc.) of the terminal and / or by transmission priority value and / or by reception priority value and / or by SL transmission with SL HARQ-ACK feedback enabled / disabled and / or by SL HARQ-ACK feedback option and / or by QoS parameter and / or by (remaining) packet delay budget (PDB) and / or by HARQ process and / or by beam process and / or by source ID and / or by destination ID and / or by transport block (TB).

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

[0261] In an embodiment of the present disclosure, the fact that the spatial setting information for transmission is the same may mean that the spatial domain TX filter of the terminal is the same for two different transmission signals. In an embodiment of the present disclosure, the fact that the spatial setting information for reception is the same may mean that the two different reception signals are in a QCL 'TypeD' relationship and / or use the same spatial RX parameters.

[0262] In the embodiments of the present disclosure, (pre)configuration may mean pre-configuration (based on signaling from a server or at the time of product shipment), configuration from a base station, configuration via PC5-RRC between terminals, etc.

[0263] The various methods of the present disclosure may be applied differently to each SL channel. The various methods of the present disclosure may be applied differently depending on the type of information contained in the SL channel.

[0264] FIG. 15 illustrates a method for a first device to perform wireless communication according to an embodiment of the present disclosure. The embodiment of FIG. 15 may be combined with various embodiments of the present disclosure.

[0265] Referring to FIG. 15, in step S1510, the first device can obtain information on a first resource set associated with a first type beam. In step S1520, the first device can obtain information on a second resource set associated with a second type beam. In step S1530, the first device can transmit a control signal to the second device for reserving at least one resource in the second resource set based on the first resource set. For example, the first type beam may include a beam of a non-directional type, and the second type beam may include a beam of a directional type.

[0266] For example, the first device may be allowed to transmit the control signal for reserving at least one resource within the second resource set based on the first resource set.

[0267] For example, the first device may not be permitted to transmit a control signal for reserving at least one resource within the first resource set based on the second resource set.

[0268] For example, the control signal for reserving at least one resource within the second resource set may include beam identifier information associated with the at least one resource within the second resource set.

[0269] For example, at least one resource within the second resource set may be reserved for beam measurements of the second device.

[0270] For example, the result of the beam measurement measured based on the at least one resource within the second resource set may be received from the second device based on the first type beam associated with the first resource set.

[0271] For example, at least one resource within the second resource set may be reserved for transmission by the first device.

[0272] For example, at least one resource within the second resource set may be selected based on sensing of the first resource set.

[0273] For example, at least one resource within the second resource set may be selected based on sensing for the second resource set, and the sensing may be performed for a receive beam direction relative to a beam direction for transmission on the at least one resource.

[0274] For example, a first candidate resource set for resource reservation or resource selection within the first resource set and a second candidate resource set for resource reservation or resource selection within the second resource set can be independently set. For example, a first threshold used for resource exclusion in the first candidate resource set can be independently set from a second threshold used for resource exclusion in the second candidate resource set.

[0275] For example, the first preferred resource set or the first non-preferred resource set within the first resource set and the second preferred resource set or the second non-preferred resource set within the second resource set can be set independently.

[0276] For example, after performing resource exclusion based on sensing, candidate resources within the first resource set may be included in the remaining candidate resources with preference over candidate resources within the second resource set based on the ratio of remaining candidate resources to the total candidate resources being below a threshold.

[0277] For example, resource reservation or resource selection within the first resource set or the second resource set may be performed based on the sum of sensing results for repeated transmissions.

[0278] For example, repeated transmissions based on the first set of resources may be allowed, and repeated transmissions based on the second set of resources may not be allowed.

[0291] For example, at least one resource within the second resource set may be selected based on sensing for the second resource set, and the sensing may be performed for a receive beam direction relative to a beam direction for transmission on the at least one resource.

[0292] For example, a first candidate resource set for resource reservation or resource selection within the first resource set and a second candidate resource set for resource reservation or resource selection within the second resource set can be independently set. For example, a first threshold used for resource exclusion in the first candidate resource set can be independently set from a second threshold used for resource exclusion in the second candidate resource set.

[0293] For example, the first preferred resource set or the first non-preferred resource set within the first resource set and the second preferred resource set or the second non-preferred resource set within the second resource set can be set independently.

[0294] For example, after performing resource exclusion based on sensing, candidate resources within the first resource set may be included in the remaining candidate resources with preference over candidate resources within the second resource set based on the ratio of remaining candidate resources to the total candidate resources being below a threshold.

[0318] FIG. 19 illustrates a signal processing circuit for a transmission signal according to an embodiment of the present disclosure. The embodiment of FIG. 19 can be combined with various embodiments of the present disclosure.

[0319] Referring to FIG. 19, 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. 19 may be performed in the processor (102, 202) and / or the transceiver (106, 206) of FIG. 18. The hardware elements of FIG. 19 may be implemented in the processor (102, 202) and / or the transceiver (106, 206) of FIG. 18. For example, blocks 1010 to 1060 may be implemented in the processor (102, 202) of FIG. 18. Additionally, blocks 1010 to 1050 may be implemented in the processor (102, 202) of FIG. 18, and block 1060 may be implemented in the transceiver (106, 206) of FIG. 18.

[0320] The codeword can be converted into a wireless signal through the signal processing circuit (1000) of FIG. 19. 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).

[0321] 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.

[0322] 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.

[0323] 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. 19. For example, a wireless device (e.g., 100, 200 of FIG. 18) 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.
