Mode for Carrying Out the Invention

[0012] In this specification, "A or B" may mean "just A," "just B," or "both A and B." Furthermore, in this specification, "A or B" may be interpreted as "A and / or B." For example, in this specification, "A, B or C" may mean "just A," "just B," "just C," or "any combination of A, B and C."

[0013] In this specification, slashes ( / ) and commas can mean "and / or". For example, "A / B" can mean "A and / or B". Thus, "A / B" can mean "just A", "just B", or "both A and B". For example, "A, B, C" can mean "A, B or C".

[0014] In this specification, "at least one of A and B" can mean "just A," "just B," or "both A and B." Furthermore, in this specification, the expressions "at least one of A or B" and "at least one of A and / or B" can be interpreted in the same way as "at least one of A and B."

[0019] In this specification, higher layer parameters may be parameters that are set for a terminal, pre-configured, or predefined. For example, a base station or network may transmit higher layer parameters to a terminal. For example, higher layer parameters may be transmitted via RRC (radio resource control) signaling or MAC (medium access control) signaling.

[0020] In this specification, "configured or defined" can be interpreted as being configured or pre-configured in the device via predefined signaling (e.g., SIB, MAC, RRC) from a base station or network. In this specification, "configured or defined" can be interpreted as being pre-configured in the device.

[0021] The technologies proposed herein 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 in wireless technologies such as UTRA (universal terrestrial radio access) and CDMA2000. TDMA can be implemented in 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 in 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.

[0022] The technologies proposed herein are implemented in 6G wireless technology and can be applied to various 6G systems. For example, 6G systems can have key factors such as eMBB (enhanced mobile broadband), URLLC (ultra-reliable low latency communications), mMTC (massive machine-type communication), AI (artificial intelligence) integrated communication, tactile internet, high throughput, high network capacity, high energy efficiency, low back haul and access network congestion, and enhanced data security.

[0023] Figure 1 shows a communication structure that can be provided in a 6G system according to one embodiment of the present disclosure. The embodiment of Figure 1 can be combined with various embodiments of the present disclosure.

[0024] The new network characteristics in 6G are as follows:

[0025] - Satellite integrated network

[0026] - Connected Intelligence: Unlike previous generations of wireless communication systems, 6G is revolutionary, updating wireless technology from "connected things" to "connected intelligence." AI can be applied to each step of the communication procedure (or each step of the signal processing described below).

[0027] - Seamless integration of wireless information and energy transfer

[0028] - Ubiquitous Super 3D Connectivity: Connecting drones and very low Earth orbit satellites to the network and core network functions creates Super 3D connectivity in 6G Ubiquitous.

[0029] The following are some common requirements for the characteristics of the new 6G network described above:

[0030] - Small cell networks

[0031] - Ultra-dense heterogeneous network

[0032] - High-capacity backhaul

[0033] - Raider technology integrated with mobile technology: High-precision localization (or location-based services) via communications is one of the functions of 6G wireless communication systems. Therefore, radar systems can be integrated with 6G networks.

[0034] - Softwareization and virtualization

[0035] The core implementation technologies for 6G systems will be described below.

[0036] - Artificial Intelligence: Introducing AI into communications simplifies and improves real-time data transmission. AI can use numerous analyses to determine how complex target operations are performed. In other words, AI can increase efficiency and reduce processing delays. Time-consuming tasks such as handover, network selection, and resource scheduling can be performed instantly using AI. AI can also play an important role in M2M, machine-to-human, and human-to-machine communications. Furthermore, AI enables rapid communication in BCI (Brain-Computer Interface). AI-based communication systems are supported by metamaterials, intelligent structures, intelligent networks, intelligent devices, intelligent radio, self-sustaining wireless networks, and machine learning.

[0037] -THz communication (terahertz communication): Data transmission rates can be increased by increasing bandwidth. This can be achieved by using sub-THz communication with a wide bandwidth and applying advanced large-scale MIMO technology. THz waves, also known as sub-millimeter radiation, typically represent a frequency band between 0.1 THz and 10 THz with wavelengths in the 0.03 mm-3 mm range. The 100 GHz-300 GHz band range (Sub THz band) is considered the main part of the THz band for cellular communication. Adding the Sub-THz band to the mmWave band increases 6G cellular communication capacity. Of the defined THz band, 300 GHz-3 THz is in the far-infrared (IR) frequency band. The 300 GHz-3 THz band is part of a broadband but is at the boundary of the broadband, just behind the RF band. Therefore, this 300 GHz-3 THz band is similar to RF. Figure 2 shows the electromagnetic spectrum according to one embodiment of the present disclosure. The embodiment in Figure 2 can be combined with various embodiments of the present disclosure. The main characteristics of THz communication include (i) a wide bandwidth available to support very high data transmission rates, and (ii) high path loss occurring at high frequencies (highly directional antennas are essential). The narrow beamwidth generated by highly directional antennas reduces interference. The small wavelength of THz signals allows more antenna elements to be integrated into equipment and BS operating in this band. Through this, advanced adaptive array techniques can be used to overcome range limitations.

[0051] - Unmanned aerial vehicles (UAVs): UAVs, or drones, will be a crucial element in 6G wireless communication. In most cases, high-speed data wireless connectivity will be provided using UAV technology. Base station (BS) entities can be installed on UAVs to provide cellular connectivity. UAVs have certain features not found in fixed BS infrastructure, such as easy deployment, strong visible line links, and the freedom of controlled mobility. During emergencies such as natural disasters, the deployment of ground communication infrastructure is not economically feasible and sometimes cannot provide services in volatile environments. UAVs can easily handle such situations. UAVs can become a new paradigm in the field of wireless communication. This technology facilitates the three basic requirements of wireless networks: eMBB, URLLC, and mMTC. UAVs can also support various purposes such as improving 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 communication.

[0052] - Advanced air mobility (AAM): AAM is a broader concept than UAM (urban air mobility), which refers to air transport used in urban areas. It can refer to transportation methods that include travel between regional hubs as well as within urban areas.

[0053] - Autonomous driving (self-driving): V2X (vehicle to everything), a crucial element in building autonomous driving infrastructure, can be a technology that allows vehicles to communicate and share information with various elements on the road for autonomous driving, including vehicle-to-vehicle (V2V) wireless communication and vehicle-to-infrastructure (V2I) wireless communication. To maximize the performance of autonomous driving and ensure high safety, fast transmission speeds and low latency technology are absolutely necessary. Furthermore, in the future, autonomous driving will go beyond simply transmitting warnings and guidance messages to the driver and will need to actively intervene in vehicle operation and directly control the vehicle in dangerous situations. For this reason, the amount of information that needs to be transmitted and received may become enormous, so it is expected that 6G will be able to maximize autonomous driving with faster transmission speeds and lower latency than 5G.

[0054] - Non-terrestrial networks (NTN): NTN can refer to a network or network segment that uses RF (radio frequency) resources onboard a satellite (or UAS (unmanned aerial system) platform). Figure 3 shows an example of a typical scenario of NTN based on a transparent payload according to one embodiment of this disclosure. Figure 4 shows an example of a typical scenario of NTN based on a regenerative payload according to one embodiment of this disclosure. Embodiments of Figure 3 or Figure 4 can be combined with various embodiments of this disclosure. Referring to Figure 3, the satellite (or UAS platform) can generate a service link with the UE. The satellite (or UAS platform) can connect to a gateway via a feeder link. The satellite can connect to a data network via a gateway. Beam footprint can mean the area from which signals transmitted by the satellite can be received. Referring to Figure 4, the satellite (or UAS platform) can generate a service link with the UE. A satellite (or UAS platform) connected to a UE can connect to other satellites (or UAS platforms) via ISLs (inter-satellite links). Other satellites (or UAS platforms) can connect to gateways via feeder links. Based on the regenerated payload, the satellite can connect to the data network via gateways with other satellites. If an ISL does not exist between satellites, a feeder link may be required between the satellite and the gateway. Figures 3 and 4 are merely examples of NTN scenarios, and NTN can implement various scenarios.For example, a satellite (or UAS platform) can implement a transparent or regenerative (with onboard processing) payload. For example, a satellite (or UAS platform) can generate various beams over a specified service area depending on the satellite's (or UAS platform's) field of view. For example, the satellite's (or UAS platform's) field of view may vary depending on the onboard antenna diagram and the 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, coding / modulation. For example, a regenerative payload is substantially the same as mounting all or part of the base station functions on a satellite (or UAS platform).

[0055] - 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 that environment. Because wireless frequency sensing does not require connection to an object via a device in the network, it can provide a service for determining object location without any device. The ability to obtain range, velocity, and angle information from wireless frequency signals can provide a wide range of new functions such as various object sensing, object recognition (e.g., vehicles, people, animals, UAVs), and high-precision location determination, tracking, and activity recognition. Wireless sensing services can provide information to various industries (e.g., unmanned aerial vehicles, smart homes, V2X, factories, railways, public safety, etc.) enabling applications such as intruder detection, control and navigation of auxiliary vehicles, trajectory tracking, collision avoidance, traffic management, and health and traffic management. In some cases, wireless sensing can use non-3GPP type sensors (e.g., radar, cameras) to further support 3GPP (registered trademark; hereafter the same) based sensing. For example, the operation of a wireless sensing service, i.e., sensing operation, can depend on the transmission, reflection, and scattering of wireless sensing signals. Therefore, wireless sensing can provide an opportunity to enhance existing communication systems with wireless and sensing networks in communication networks. Figure 5 shows an example of sensing operation according to one embodiment of the present disclosure. The embodiment of Figure 5 can be combined with various embodiments of the present disclosure. Specifically, Figure 5(a) shows an example of sensing using a sensing receiver and sensing transmitter located in the same position (e.g., monostatic sensing), and Figure 5(b) shows an example of sensing using a separated sensing receiver and sensing transmitter (e.g., bistatic sensing).

[0056] The layers of the Radio Interface Protocol (RRC) between a terminal and a network can be divided into L1 (First Layer), L2 (Second Layer), and L3 (Third Layer) based on the three lower layers of the Open System Interconnection (OSI) standard model, which is widely known in communication systems. Of these, the physical layer, which belongs to the first layer, provides information transfer services using physical channels, while the RRC (Radio Resource Control) layer, located in the third layer, plays the role of controlling radio resources between the terminal and the network. To this end, the RRC layer exchanges RRC messages between the terminal and the base station.

[0057] The physical layer provides information transfer services to higher layers using physical channels. The physical layer is connected to the higher layer, the MAC (Medium Access Control) layer, via transport channels. Data moves between the MAC layer and the physical layer via these transport channels. Transport channels are classified according to how and with what characteristics data is transmitted via the wireless interface.

[0058] Data travels between different physical layers, i.e., between the physical layers of the transmitter and receiver, via a physical channel. This physical channel can be modulated using the OFDM (Orthogonal Frequency Division Multiplexing) method, utilizing time and frequency as wireless resources.

[0059] The MAC layer provides services to the higher-level RLC (radio link control) layer via logical channels. The MAC layer provides mapping functionality from multiple logical channels to multiple transport channels. Furthermore, the MAC layer provides logical channel multiplexing functionality through mapping from multiple logical channels to a single transport channel. The MAC sub-layer provides data transfer services on logical channels.

[0060] The RLC hierarchy performs concatenation, segmentation, and reassembly of RLC SDUs (Service Data Units). To ensure the diverse Quality of Service (QoS) requirements of radio bearers (RBs), the RLC hierarchy provides three operating modes: Transparent Mode (TM), Unacknowledged Mode (UM), and Acknowledged Mode (AM). AM RLC provides error correction via ARQ (automatic repeat request).

[0061] The RRC (Radio Resource Control) layer is defined only in the control plane. The RRC layer is responsible for controlling logical channels, transmit channels, and physical channels in relation to the configuration, reconfiguration, and release of radio bearers. RB refers to the logical path provided by the first layer (physical layer or PHY layer) and the second layer (MAC layer, RLC layer, PDCP (Packet Data Convergence Protocol) layer, SDAP (Service Data Adaptation Protocol) layer) for data transmission between the terminal and the network.

[0062] The functions of the PDCP hierarchy on the user plane include the transmission of user data, header compression, and encryption. The functions of the PDCP hierarchy on the control plane include the transmission of control plane data and encryption / integrity protection.

[0063] The SDAP (Service Data Adaptation Protocol) layer is defined only at the user level. The SDAP layer performs tasks such as mapping QoS flows to data radio bearers and marking QoS flow identifiers (IDs) in downlink and uplink packets.

[0064] Setting up a Radio Bearing (RB) refers to the process of defining the characteristics of the radio protocol hierarchy and channel in order to provide a specific service, and setting the specific parameters and operating methods for each. Furthermore, RBs are divided into two types: SRB (Signaling Radio Bearer) and DRB (Data Radio Bearer). The SRB is used as a channel for transmitting RRC messages in the control plane, while the DRB is used as a channel for transmitting user data in the user plane.

[0065] When an RRC connection is established between the terminal's RRC layer and the base station's RRC layer, the terminal enters the RRC_CONNECTED state; otherwise, it enters the RRC_IDLE state. In the case of NR, an additional RRC_INACTIVE state is defined, in which a terminal in the RRC_INACTIVE state can maintain its connection with the core network and release its connection with the base station.

[0066] Downlink transport channels, which transmit data from the network to terminals, include BCH (Broadcast Channel) for transmitting system information and Downlink SCH (Shared Channel) for transmitting user traffic and control messages. Downlink multicast or broadcast service traffic or control messages can be transmitted via Downlink SCH or via a separate Downlink MCH (Multicast Channel). On the other hand, uplink transport channels, which transmit data from terminals to the network, include RACH (Random Access Channel) for transmitting initial control messages and Uplink SCH (Shared Channel) for transmitting user traffic and control messages.

[0067] Above the transport channel level, logical channels mapped to the transport channel include BCCH (Broadcast Control Channel), PCCH (Paging Control Channel), CCCH (Common Control Channel), MCCH (Multicast Control Channel), and MTCH (Multicast Traffic Channel).

[0068] Radio frames can be used for uplink and downlink transmissions. A radio frame has a length of 10ms and can be defined as two 5ms half-frames (HF). A half-frame can contain five 1ms 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 by a cyclic prefix (CP).

[0069] When normal CP is used, each slot can contain 14 symbols. When extended CP is used, each slot can contain 12 symbols. Here, 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).

[0070] Table 2 below shows the number of symbols per slot (N) depending on the SCS setting (u) when a 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.

[0071] [Table 2]

[0072] Figure 6 shows a frame slot structure according to one embodiment of the present disclosure. The embodiment in Figure 6 can be combined with various embodiments of the present disclosure.

[0073] Referring to Figure 6, a slot contains multiple symbols in the time domain. A carrier wave contains multiple subcarriers in the frequency domain. An RB (Resource Block) can be defined as multiple (e.g., 12) consecutive subcarriers in the frequency domain. A BWP (Bandwidth Part) can be defined as multiple consecutive (P)RBs ((Physical)Resource Blocks) in the frequency domain and can correspond to a single numerology (e.g., SCS, CP length, etc.). A carrier wave can contain up to N (e.g., 5) BWPs. Data communication can be performed via activated BWPs. Each element is called a Resource Element (RE) in the resource grid and can be mapped to a single complex symbol.

[0074] A carrier wave contains multiple subcarriers in the frequency domain. A Resource Block (RB) can be defined as multiple (e.g., 12) consecutive subcarriers in the frequency domain. A Bandwidth Part (BWP) can be defined as multiple consecutive (P)RBs ((Physical) Resource Blocks) in the frequency domain and can correspond to one numerology (e.g., SCS, CP length). A carrier wave can contain up to N (e.g., 5) BWPs. Data communication can be performed via active BWPs. Each element can be called a Resource Element (RE) in the resource grid and can be mapped to one complex symbol.

[0075] A Bandwidth Part (BWP) is a contiguous set of Physical Resource Blocks (PRBs) for a given numerology. PRBs can be selected from a contiguous subset of Common Resource Blocks (CRBs) for a given numerology on a given carrier.

[0076] FIG. 7 shows 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.

[0077] Referring to FIG. 7, a CRB (common resource block) is a carrier resource block numbered from one end to the other end of a carrier band. And a PRB is a resource block numbered within each BWP. Point A can indicate a common reference point for a resource block grid.

[0078] A BWP can be set by point A, an offset (N start BWP ) from point A, and a bandwidth (N size BWP ). For example, point A is an external reference point of the PRB of the carrier where sub - carrier 0 of all numerologies (e.g., all numerologies supported by the network in the corresponding carrier) is aligned. For example, the offset is the PRB interval between the lowest sub - carrier and point A for a given numerology. For example, the bandwidth is the number of PRBs for a given numerology.

[0079] SLSS (Sidelink Synchronization Signal) is a sidelink-specific sequence that may include a PSSS (Primary Sidelink Synchronization Signal) and an 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, a length-127M-sequence can be used for the S-PSS, and a length-127Gold-sequence can be used for the S-SSS. For example, a terminal can use the S-PSS to detect the initial signal and acquire synchronization. For example, a terminal can use the S-PSS and S-SSS to acquire detailed synchronization and detect the synchronization signal ID.

[0080] The PSBCH (Physical Sidelink Broadcast Channel) is a broadcast channel that transmits fundamental (system) information that terminals should know first before transmitting or receiving SL signals. For example, this fundamental information includes information related to SLSS, duplex mode (DM), TDDUL / DL (Time Division Duplex Uplink / Downlink) configuration, resource pool-related information, application types related to SLSS, subframe offset, and broadcast information. For example, to evaluate PSBCH performance, in NR V2X, the size of the PSBCH payload is 56 bits, including a 24-bit CRC (Cyclic Redundancy Check).

[0081] S-PSS, S-SSS, and PSBCH can be included in a block format that supports periodic transmission (e.g., an SLSS (Synchronization Signal) / PSBCH block, hereinafter referred to as S-SSB (Sidelink-Synchronization Signal Block)). The S-SSB can have the same numerology (i.e., SCS and CP lengths) as the PSCCH (Physical Sidelink Control Channel) / PSSCH (Physical Sidelink Shared Channel) in the carrier, and its transmission bandwidth is within a (pre-configured) Sidelink Bandwidth Part (SL BWP). For example, the bandwidth of the S-SSB is 11RB (Resource Block). For example, the PSBCH spans 11RB. The frequency position of the S-SSB can be (pre-configured). Therefore, the terminal does not need to perform hypothesis detection on frequency to find the S-SSB in the carrier.

[0082] In this specification, PSCCH can be replaced with control channels, physical control channels, control channels associated with side links, physical control channels associated with side links, etc. In this specification, PSSCH can be replaced with shared channels, physical shared channels, shared channels associated with side links, physical shared channels associated with side links, etc.

[0083] Figure 8 illustrates a procedure in which a terminal performs V2X or SL communication according to a resource allocation mode, according to one embodiment of the present disclosure. The embodiment in Figure 8 can be combined with various embodiments of the present disclosure.

[0084] Referring to Figure 8(a), in resource allocation mode 1, the base station can schedule SL resources to be used by the terminal for SL transmission. For example, in step S800, the base station can transmit information related to the SL resources and / or information related to the 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.

[0085] For example, the first terminal can receive from the base station information related to a DG (dynamic grant) resource and / or information related to a CG (configured grant) resource. 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 the base station configures / assigns to the first terminal via DCI (downlink control information). In this specification, a CG resource may be a (periodic) resource that the base station configures / assigns to the first terminal via DCI and / or RRC messages. For example, in the case of a CG type 1 resource, the base station may send an RRC message containing 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 send an RRC message containing information related to the CG resource to the first terminal, and the base station may send DCI related to the activation or release of the CG resource to the first terminal.

[0086] In step S810, the first terminal can transmit a PSCCH (e.g., SCI (Sidelink Control Information) or 1st-stage SCI) to the second terminal based on the resource scheduling. In step S820, the first terminal can transmit a PSSCH (e.g., 2nd-stage SCI, MAC PDU, data, etc.) associated with the PSCCH to the second terminal. In step S830, the first terminal can receive a PSFCH associated with the PSCCH / PSSCH from the second terminal. For example, HARQ feedback information (e.g., NACK information or ACK information) can be received from the second terminal via the PSFCH. In step S840, the first terminal can transmit / report the HARQ feedback information to the base station via PUCCH or 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 pre-configured rules. For example, the DCI may be a DCI for scheduling SLs.

[0087] Referring to Figure 8(b), in resource allocation mode 2, the terminal can determine an SL transmission resource from the SL resources set by the base station / network or from the pre-configured SL resources. For example, the set SL resources or pre-configured 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 select resources itself from the configured resource pool and perform SL communication. For example, the terminal can perform sensing and resource (re)selection procedures and select resources itself within the selection window. For example, the sensing may be performed in units of subchannels. For example, in step S810, the first terminal that has selected resources itself from the resource pool can use those resources to send PSCCH (e.g., SCI (Sidelink Control Information) or 1 st -stage SCI) can be transmitted to the second terminal. In step S820, the first terminal transmits a PSSCH (e.g., 2) associated with the PSCCH. nd -Stage SCI, MAC PDU, data, etc. can be transmitted to the second terminal. In step S830, the first terminal can receive the PSFCH associated with the PSCCH / PSSCH from the second terminal.

[0088] Referring to Figure 8(a) or (b), for example, the first terminal can transmit an SCI over the PSCCH to the second terminal. Alternatively, for example, the first terminal can transmit two consecutive SCIs (e.g., a 2-stage SCI) over the PSCCH and / or PSSCH to the second terminal. In this case, the second terminal can decode the two consecutive SCIs (e.g., a 2-stage SCI) to receive the PSSCH from the first terminal. In this specification, an SCI transmitted over the PSCCH is 1 st SCI, 1st SCI, 1 st -stage SCI or 1 st -Stage SCI format, which can be called the SCI format, is transmitted over PSSCH. nd SCI, 2nd SCI, 2 nd-stage SCI or 2 nd - This can be called the stage SCI format.

[0089] Referring to Figure 8(a) or (b), in step S830, the first terminal can receive the PSFCH. For example, the first and second terminals can determine the PSFCH resource, and the second terminal can use the PSFCH resource to send HARQ feedback to the first terminal.

[0090] Referring to Figure 8(a), in step S840, the first terminal can transmit SL HARQ feedback to the base station via PUCCH and / or PUSCH.

[0091] On the other hand, in the next-generation system, terminals will be able to perform inter-terminal transmission and reception (e.g., SL transmission and reception) via multiple inter-terminal communication carriers (e.g., SL communication carriers), and when moving between multiple inter-terminal channels (e.g., SL channels) via each inter-terminal communication carrier (e.g., SL communication carrier), data will be transmitted or received simultaneously. Through this, terminals can increase the data rate for inter-terminal communication (e.g., SL communication) and / or improve detection performance through packet duplication, etc.

[0092] On the other hand, inter-terminal transmission and reception (e.g., SL transmission and reception) via multiple inter-terminal communication carriers (e.g., SL communication carriers) can be linked to different service types and / or quality of service (e.g., QoS) depending on the inter-terminal communication carrier (e.g., SL communication carrier).

[0093] Figure 9 shows the frequency bandwidth during carrier integration according to one embodiment of the present disclosure. The embodiment of Figure 9 can be combined with various embodiments of the present disclosure.

[0094] Referring to Figure 9, the first carrier wave and the second carrier wave are shown. For example, if the terminal's capability allows carrier wave aggregation, the terminal can aggregate the first carrier wave and the second carrier wave to perform terminal-to-terminal communication (e.g., SL communication).

[0095] For example, in Figure 9, the first carrier wave and the second carrier wave are separated from each other in the frequency domain, but in reality they can be adjacent to each other or they can be non-adjacent carrier waves. Alternatively, for example, the first carrier wave and the second carrier wave can be in an intra-band relationship with each other, or they can be in an inter-band relationship with each other. For example, regardless of the form of carrier waves that are combined, when the first carrier wave and the second carrier wave are combined, the terminal can use the first carrier wave and the second carrier wave simultaneously to perform terminal-to-terminal communication.

[0096] On the other hand, the location (or temporal location) of inter-terminal physical feedback channel (e.g., PSFCH) opportunities can be aligned between different inter-terminal communication carriers (e.g., SL communication carriers), aggregated inter-terminal communication carriers (e.g., aggregated SL communication carriers), and / or resource pools.

[0097] For example, even if a particular first inter-terminal communication carrier (e.g., SL communication carrier) and / or a first integrated inter-terminal communication carrier (e.g., integrated SL communication carrier) does not have inter-terminal synchronization signal block (e.g., S-SSB) resources, all or part of the slots of the first inter-terminal communication carrier (e.g., SL communication carrier) that overlap (temporarily) with inter-terminal synchronization signal block (e.g., S-SSB) resources present in other inter-terminal communication carriers (e.g., SL communication carriers) and / or other integrated carriers can be excluded from the slot set targeted by the resource pool.

[0098] For example, a virtual inter-terminal synchronization signal block (e.g., S-SSB) resource can be (pre-configured) for a specific first inter-terminal communication carrier (e.g., SL communication carrier) and / or a first integrated inter-terminal communication carrier (e.g., integrated SL communication carrier), and all or part of the virtual inter-terminal synchronization signal block (e.g., S-SSB) resource can be excluded from the slot set targeted by the resource pool. For example, the virtual inter-terminal synchronization signal block (e.g., S-SSB) resource may not actually be used for transmitting and / or receiving inter-terminal synchronization signal blocks (e.g., S-SSB).

[0099] For example, a terminal can expect that the number of terminal-available starting symbols (e.g., SL-available starting symbols), the number of terminal-available symbols (e.g., SL-available symbols), and / or the last symbol among the terminal-available symbols (e.g., SL-available symbols) in a slot are the same between different terminal-to-terminal communication carriers (e.g., SL-communication carriers) and / or integrated terminal-to-terminal communication carriers (e.g., integrated SL-communication carriers).

[0100] For example, a terminal can expect that the numerology, subcarrier spacing, and / or cyclic prefix (e.g., CP) lengths are the same between different inter-terminal communication carriers (e.g., SL communication carriers), integrated inter-terminal communication carriers (e.g., integrated SL communication carriers), and / or integrated inter-terminal subbandwidths (e.g., integrated SL BWP).

[0101] For example, the number of available starting symbols and / or inter-terminal available symbols (e.g., SL communication symbols) in a slot can be set to be different for each carrier between different inter-terminal communication carriers (e.g., SL communication carriers) and / or integrated inter-terminal communication carriers (e.g., integrated SL communication carriers). However, in a slot containing an inter-terminal physical feedback channel (e.g., PSFCH) resource, the number of available starting symbols and / or inter-terminal available symbols (e.g., SL available symbols) in a slot can be set to be the same between inter-terminal communication carriers (e.g., SL communication carriers) and / or integrated inter-terminal communication carriers (e.g., integrated SL communication carriers) with different symbol intervals for inter-terminal physical channels (e.g., PSCCH / PSSCH).

[0102] For example, the number of available starting symbols and / or symbols available between terminals (e.g., symbols available for SL) can be set to be different for the first slot set and the second slot set for a particular inter-terminal communication carrier (e.g., SL communication carrier).

[0103] and / or, for example, in relation to the inter-terminal available symbols (e.g., SL available symbols), i) the length of the inter-terminal physical channel (e.g., PSCCH / PSSCH) symbol interval of the first slot set may be set to be the same as the length of the inter-terminal physical channel (e.g., PSCCH / PSSCH) symbol interval of a slot that does not contain an inter-terminal physical feedback channel (e.g., PSFCH) in another inter-terminal communication carrier (e.g., SL communication carrier), and / or ii) the length of the inter-terminal physical channel (e.g., PSCCH / PSSCH) symbol interval of the second slot set may be set to be the same as the length of the inter-terminal physical channel (e.g., PSCCH / PSSCH) symbol interval of a slot that contains an inter-terminal physical feedback channel (e.g., PSFCH) in another inter-terminal communication carrier (e.g., SL communication carrier).

[0104] For example, between different inter-terminal communication carriers (e.g., SL communication carriers) and / or integrated inter-terminal communication carriers (e.g., integrated SL communication carriers), at least one resource pool (for each carrier) can be configured to have the same set of inter-terminal slots (e.g., SL slots). That is, for example, between different inter-terminal communication carriers (e.g., SL communication carriers) and / or integrated inter-terminal communication carriers (e.g., integrated SL communication carriers), at least one resource pool must have the same set of inter-terminal slots (e.g., SL slots).

[0105] For example, the resource pool may be a resource pool in which (all) terminal-to-terminal physical feedback channel (e.g., PSFCH) resources are configured.

[0106] For example, a set of slots corresponding to the resource pool(s) of each carrier can be time-division multiplexed (e.g., TDM) between different inter-terminal communication carriers (e.g., SL communication carriers) and / or integrated inter-terminal communication carriers (e.g., integrated SL communication carriers). For example, some of the resource pools may be configured with inter-terminal physical feedback channel (e.g., PSFCH) resources, while the remaining resource pools may not be configured with inter-terminal physical feedback channel (e.g., PSFCH) resources.

[0107] For example, the transmission time and reception time of an inter-terminal synchronization signal block (e.g., S-SSB) may be the same between different inter-terminal communication carriers (e.g., SL communication carriers) and / or integrated inter-terminal communication carriers (e.g., integrated SL communication carriers). For example, the time allocation parameters associated with the inter-terminal synchronization block (e.g., sl-SSB-Time Allocation 1, sl-SSB-Time Allocation 2, and / or sl-SSB-Time Allocation 3) may be the same between different inter-terminal communication carriers (e.g., SL communication carriers) and / or integrated inter-terminal communication carriers (e.g., integrated SL communication carriers).

[0108] For example, the positions of DFN#0 and / or SFN#0 may be the same (for each carrier) between different inter-terminal communication carriers (e.g., SL communication carriers) and / or integrated inter-terminal communication carriers (e.g., integrated SL communication carriers).

[0109] For example, terminals can be expected to be configured such that the minimum inter-terminal physical shared channel (e.g., PSSCH) to inter-terminal physical feedback channel (e.g., PSFCH) timing is the same between different inter-terminal communication carriers (e.g., SL communication carriers) and / or integrated inter-terminal communication carriers (e.g., integrated SL communication carriers).

[0110] For example, the inter-terminal physical feedback channel (PSFCH) resource period can be set to be the same between different inter-terminal communication carriers (e.g., SL communication carriers) and / or integrated inter-terminal communication carriers (e.g., integrated SL communication carriers).

[0111] For example, a virtual inter-terminal physical feedback channel (e.g., PSFCH) resource can be (pre-configured) for a specific first inter-terminal communication carrier (e.g., SL communication carrier) and / or a first integrated inter-terminal communication carrier (e.g., integrated SL communication carrier), and the virtual inter-terminal physical feedback channel (e.g., PSFCH) resource may not be used for actual inter-terminal synchronization signal block (e.g., S-SSB) transmission and / or reception.

[0112] In various embodiments of this disclosure, the features for inter-terminal physical feedback channel (e.g., PSFCH) resource configuration can be limited (interpreted) to configuration for an inter-terminal communication carrier (e.g., SL communication carrier) that includes a resource pool in which inter-terminal physical feedback channel (e.g., PSFCH) resources are configured.

[0113] On the other hand, at least in the case of intraband carrier aggregation (e.g., CA), terminal-to-terminal communication terminals (e.g., SL terminals) may not be able to simultaneously perform terminal-to-terminal transmission (e.g., SL transmission) and terminal-to-terminal reception (e.g., SL reception) operations with respect to other terminal-to-terminal communication carriers (e.g., SL communication carriers) at the same time.

[0114] For example, when a terminal is (re)selecting a resource, it can align inter-terminal physical channel (e.g., PSCCH / PSSCH) transmit slots as much as possible for multiple inter-terminal communication carriers (e.g., SL communication carriers) and / or integrated inter-terminal communication carriers (e.g., integrated SL communication carriers).

[0115] For example, during resource (re)selection, if a terminal selects a terminal-to-terminal physical channel (e.g., PSCCH / PSSCH) transmission resource for a specific terminal-to-terminal communication carrier (e.g., SL communication carrier), the terminal may prioritize selecting resources within other terminal-to-terminal integrated carriers (e.g., SL integrated carriers) and / or terminal-to-terminal physical channel (e.g., PSCCH / PSSCH) slots selected in the resource pool. This may reduce the number of non-monitored slots due to terminal transmissions.

[0116] For example, during resource (re)selection, a terminal can select multiple inter-terminal communication carriers (e.g., SL communication carriers) and / or integrated inter-terminal communication carriers (e.g., integrated SL communication carriers) such that the inter-terminal physical channel (e.g., PSCCH / PSSCH) transmission slots do not overlap as much as possible.

[0117] For example, when a terminal selects an inter-terminal physical channel (e.g., PSCCH / PSSCH) transmission resource for a specific inter-terminal communication carrier (e.g., SL communication carrier) during resource (re)selection, the terminal may deprioritize the selection priority of other inter-terminal integrated carriers (e.g., SL integrated carriers) and / or resources within the selected inter-terminal physical channel (e.g., PSCCH / PSSCH) slot in the resource pool. This may be because the detection performance of each channel decreases due to power distribution when a terminal transmits inter-terminal channels (e.g., SL channels) simultaneously over multiple carriers.

[0118] For example, during resource (re)selection, the terminal can align inter-terminal physical channel (e.g., PSCCH / PSSCH) receive slots as much as possible with respect to multiple inter-terminal communication carriers (e.g., SL communication carriers) and / or integrated inter-terminal communication carriers (e.g., integrated SL communication carriers).

[0119] For example, during resource (re)selection, a terminal can select multiple inter-terminal communication carriers (e.g., SL communication carriers) and / or integrated inter-terminal communication carriers (e.g., integrated SL communication carriers) such that the inter-terminal physical channel (e.g., PSCCH / PSSCH) transmit slots and inter-terminal physical channel (e.g., PSCCH / PSSCH) receive slots do not overlap as much as possible.

[0120] For example, during resource (re)selection, a terminal can (re)select an inter-terminal physical channel (e.g., PSCCH / PSSCH) transmission resource for multiple inter-terminal communication carriers (e.g., SL communication carriers) and / or integrated inter-terminal communication carriers (e.g., integrated SL communication carriers) such that the transmission time of the inter-terminal physical feedback channel (e.g., PSFCH) and the reception time of the inter-terminal physical feedback channel (e.g., PSFCH) overlap as much as possible.

[0121] For example, during resource (re)selection, if a terminal selects a terminal-to-terminal physical channel (e.g., PSCCH / PSSCH) transmission resource for a specific terminal-to-terminal communication carrier (e.g., SL communication carrier), the terminal may deprioritize the selection priority of resources in other terminal-to-terminal integrated carriers (e.g., SL integrated carriers) and / or in terminal-to-terminal physical channel (e.g., PSCCH / PSSCH) slots scheduled for reception in the resource pool.

[0122] For example, during resource (re)selection operation, if a terminal selects an inter-terminal physical channel (e.g., PSCCH / PSSCH) transmission resource for a specific inter-terminal communication carrier (e.g., SL communication carrier), the terminal may prioritize the selection of a resource for an inter-terminal physical feedback channel (e.g., PSFCH) corresponding to the inter-terminal physical shared channel (e.g., PSSCH) when the terminal does not expect to transmit via the inter-terminal physical feedback channel (e.g., PSFCH) (i.e., when inter-terminal physical feedback channel (e.g., PSFCH) transmission is not planned).

[0123] For example, if a terminal receives / detects a preferred resource set for a resource pool within a specific inter-terminal communication carrier (e.g., SL communication carrier) from another terminal, and the terminal performs resource selection for other (multiple) inter-terminal communication carriers (e.g., SL communication carriers) and / or an integrated inter-terminal communication carrier (e.g., an integrated SL communication carrier), the terminal may preferentially select as transmission resources slot sets in the resource pools within each inter-terminal communication carrier (e.g., SL communication carrier) that overlap with the preferred resource set or contain resources from the preferred resource set.

[0124] For example, if a terminal receives / detects a non-priority resource set for a resource pool within a specific inter-terminal communication carrier (e.g., SL communication carrier) from another terminal, and the terminal performs resource selection for other (multiple) inter-terminal communication carriers (e.g., SL communication carriers) and / or an integrated inter-terminal communication carrier (e.g., an integrated SL communication carrier), the terminal may choose not to use slot sets that overlap with the non-priority resource set or that contain resources from the non-priority resource set as transmission resources in the resource pool within each inter-terminal communication carrier (e.g., SL communication carrier), or may deprioritize the selection priority of those resources.

[0125] For example, the operation can be applied differently depending on the factors that generate the non-priority resource set. For example, the operation can be limited to being performed when the non-priority resource set is generated based on an area where the receiving terminal cannot receive data between terminals (e.g., SL reception).

[0126] In various embodiments of this disclosure, the operation of a terminal can be performed differently depending on the combination of the congestion control level, the inter-terminal communication carrier (e.g., SL communication carrier) (group), the transmit power level, and / or the terminal's transmit priority(s), and / or depending on the (pre-)settings.

[0127] According to one embodiment of the present disclosure, the symbol intervals for inter-terminal physical channels (e.g., PSCCH / PSSCH) within the same slot derived in different inter-terminal communication carriers (e.g., SL communication carriers) and / or integrated inter-terminal communication carriers (e.g., integrated SL communication carriers) for a terminal are all the same, and / or the starting symbols are the same.

[0128] For example, the time-domain location of an inter-terminal physical feedback channel (e.g., PSFCH) resource within the same slot derived for different inter-terminal communication carriers (e.g., SL communication carriers) and / or integrated inter-terminal communication carriers (e.g., integrated SL communication carriers) for a terminal may be the same.

[0129] For example, in the above, the inter-terminal physical feedback channel (e.g., PSFCH) slots of the first inter-terminal communication carrier (e.g., SL communication carrier) may not overlap with the slot set of the second inter-terminal communication carrier (e.g., SL communication carrier).

[0130] For example, in the above, the inter-terminal physical feedback channel (e.g., PSFCH) slots of the first inter-terminal communication carrier (e.g., SL communication carrier) overlap with the slot set of the second inter-terminal communication carrier (e.g., SL communication carrier), but in the said slot, the last time point (e.g., symbol) of the inter-terminal physical channel (e.g., PSCCH / PSSCH) of the second inter-terminal communication carrier (e.g., SL communication carrier) can be time-division multiplexed (e.g., TDM) with the inter-terminal physical feedback channel (e.g., PSFCH) resource (symbol) of the first inter-terminal communication carrier (e.g., SL communication carrier). And / or, for example, in the above case, there may be a symbol gap between the start time (symbol) of the inter-terminal physical feedback channel (e.g., PSFCH) and the last time point (symbol) of the inter-terminal physical channel (e.g., PSCCH / PSSCH).

[0131] For example, in different inter-terminal communication carriers (e.g., SL communication carriers) and / or integrated inter-terminal communication carriers (e.g., integrated SL communication carriers) (with respect to a terminal), the derived inter-terminal physical feedback channel (e.g., PSFCH) slot sets are all the same, and / or one inter-terminal physical feedback channel (e.g., PSFCH) slot set may be in the form of a superset or subset of other inter-terminal physical feedback channel (e.g., PSFCH) slot sets.

[0132] Figure 10 shows the layout of terminal-to-terminal physical feedback channel (e.g., PSFCH) symbols during carrier integration according to one embodiment of the present disclosure. The embodiment of Figure 10 can be combined with various embodiments of the present disclosure.

[0133] Referring to Figure 10, a first carrier and a second carrier are shown. Here, we assume that the terminal's capability allows carrier aggregation and that carrier aggregation is performed on the first carrier and the second carrier.

[0134] For example, an inter-terminal physical feedback (e.g., PSFCH) transmission resource can be set for the first carrier wave and the second carrier wave, respectively. For example, the time unit of the inter-terminal physical feedback (e.g., PSFCH) transmission resource can be a symbol. For example, the inter-terminal physical feedback (e.g., PSFCH) transmission resource included in the first carrier wave and the inter-terminal physical feedback (e.g., PSFCH) transmission resource included in the second carrier wave can be aligned. That is, the symbols of the inter-terminal physical feedback (e.g., PSFCH) transmission resource included in the first carrier wave and the symbols of the inter-terminal physical feedback (e.g., PSFCH) transmission resource included in the second carrier wave can all be the same symbol.

[0135] For example, when carrier aggregation is performed on the first carrier and the second carrier, the terminal can expect the inter-terminal physical feedback (e.g., PSFCH) transmission resources included in the first carrier and the second carrier to be aligned. For example, when carrier aggregation is performed on the first carrier and the second carrier, the terminal can be configured to align the inter-terminal physical feedback (e.g., PSFCH) transmission resources included in the first carrier and the second carrier.

[0136] Here, if the inter-terminal physical feedback (e.g., PSFCH) transmission resources included in each carrier wave are not aligned in the integrated carrier wave as described above, when inter-terminal physical feedback (e.g., PSFCH) transmission is performed on one carrier wave, an automatic gain control problem may occur on the other carrier waves. That is, because the transmission power may suddenly increase at a specific symbol time in a slot, if the inter-terminal physical feedback (e.g., PSFCH) transmission resources included in each carrier wave are not aligned, it may be difficult to distribute the transmission power normally in the slot including the time in question on the carrier wave where the inter-terminal physical feedback (e.g., PSFCH) transmission resources are not set, and therefore it may be difficult to perform normal transmission and reception operations. Depending on the various embodiments of this disclosure, if the inter-terminal physical feedback (e.g., PSFCH) transmission resources included in each carrier wave are aligned in the integrated carrier wave, the automatic gain control problem described above can be resolved in the integrated carrier wave, and inter-terminal communication via carrier integration can be performed smoothly.

[0137] For example, a terminal can generate / establish a unicast link via multiple inter-terminal communication carriers (e.g., SL communication carriers), and / or information regarding the inter-terminal communication carriers (e.g., SL communication carriers) can be set via inter-terminal related information / signaling exchange, etc., when the unicast link is generated / established.

[0138] For example, when a terminal establishes a unicast link via multiple terminal-to-terminal communication carriers (e.g., SL communication carriers), if the link quality for a particular terminal-to-terminal communication carrier (e.g., SL communication carrier) is determined to be below a certain level (for example, if the number of discontinuous transmissions (e.g., DTX) is equal to or exceeds a threshold set (in advance) or via PC5-RRC), and / or if there is a service type that is resourceted only on the terminal-to-terminal communication carrier (e.g., SL communication carrier), the terminal may determine (declare) RLF (radio link failure) for the unicast link.

[0139] For example, a terminal can generate / establish a unicast link via multiple inter-terminal communication carriers (e.g., SL communication carriers), and / or information regarding the inter-terminal communication carriers (e.g., SL communication carriers) can be set via inter-terminal related information / signaling exchange, etc., when the unicast link is generated / established.

[0140] For example, when establishing a unicast link via multiple terminal-to-terminal communication carriers (e.g., SL communication carriers), if the link quality for a particular terminal-to-terminal communication carrier (e.g., SL communication carrier) is determined to be below a certain level (for example, if the number of discontinuous transmissions (e.g., DTX) is equal to or exceeds a threshold set (in advance) or set via PC5-RRC), if the service type supported on the terminal-to-terminal communication carrier (e.g., SL communication carrier) is supported on other terminal-to-terminal communication carriers (e.g., SL communication carriers) or terminal-to-terminal integrated carriers (e.g., SL integrated carriers), and / or if the link quality for the other terminal-to-terminal communication carriers (e.g., SL communication carriers) is determined to be above or above a certain level, the terminal may suspend / cancel a radio link failure (e.g., RLF) declaration for the unicast link.

[0141] For example, candidate resources that overlap with resources associated with a slot where monitoring of the inter-terminal physical channel (e.g., PSCCH and / or PSSCH) could not be performed due to terminal transmission (resources in the slot after a certain total or partial resource reservation period value set in the resource pool from the slot) can be excluded from the available resource set, and / or the failed monitoring can be limited to transmissions within the resource pool where resource (re)selection is performed and / or the inter-terminal communication carrier (e.g., SL communication carrier) to which the resource pool belongs.

[0142] For example, if the amount of available resource sets (or the number of resources) is below or less than a certain level (e.g., a (pre)set threshold), the terminal may preferentially cancel resource exclusions derived from unmonitored slots by transmission in other resource pools and / or inter-terminal communication carriers (e.g., SL communication carriers) other than the inter-terminal resource pool and / or inter-terminal communication carrier (e.g., SL communication carrier) for resource (re)selection.

[0143] For example, when a terminal re-selects a resource, it may prioritize maintaining the inter-terminal communication carrier (e.g., SL communication carrier) and / or transmit resource pool associated with (or containing) the previously selected resource.

[0144] For example, when a terminal re-selects a resource, it may select a different inter-terminal communication carrier (e.g., SL communication carrier) and / or transmit resource pool from the one associated with the previously selected resource, and at least the service type and / or quality of service (e.g., QoS) supported by the newly selected different inter-terminal communication carrier (e.g., SL communication carrier) may be the same as or partially overlap with the service type and / or quality of service (e.g., QoS) supported by the inter-terminal communication carrier (e.g., SL communication carrier) associated with the previously selected resource.

[0145] For example, when a terminal uses multiple aggregated cells, carriers, and / or partial bandwidths for terminal-to-terminal communication (e.g., SL communication) (or when configured to do so), the terminal may refer to, use, or consider information regarding time-division multiplexing (e.g., TDD) base station-to-terminal (e.g., UL-DL) configurations for specific cells or carriers (e.g., specifying slot format types such as terminal-to-base station (e.g., UL), base station-to-terminal (e.g., DL), or flexible) or cell-specific terminal-to-base station (e.g., UL) slots and / or symbols when configuring resource pools belonging to multiple aggregated cells, carriers, and / or partial bandwidths (e.g., BWP).

[0146] For example, the particular cell or carrier wave may be a primary cell, a (pre)configured cell or carrier wave, and / or a cell or carrier wave on which inter-terminal synchronization signal blocks (e.g., S-SSB) are transmitted or received, or on which inter-terminal synchronization signal block (e.g., S-SSB) resources are configured.

[0147] For example, if a terminal uses multiple aggregated cells, carriers, and / or partial bandwidths for terminal-to-terminal communication (e.g., SL communication) (or if configured to do so), the time-division multiplexing (e.g., TDD) base station-to-terminal communication (e.g., UL-DL) settings for each cell or carrier (e.g., indicating a slot format type such as terminal-to-base station (e.g., UL) or base station-to-terminal (e.g., DL) or flexible) or cell-specific terminal-to-base station (e.g., UL) slot and / or symbol information may all be the same.

[0148] For example, if a terminal uses multiple aggregated cells, carriers, and / or partial bandwidths for inter-terminal communication (e.g., SL communication) (or if configured to do so), the terminal can expect that all or part of the set of slots subject to resource pooling is the same for each cell or carrier.

[0149] On the other hand, when controlling the power of inter-terminal transmissions (e.g., SL transmissions) between different inter-terminal communication carriers (e.g., SL communication carriers) and / or integrated inter-terminal communication carriers (e.g., integrated SL communication carriers), if the total power is greater than the terminal's maximum transmission power, the terminal can reduce the power of lower-priority inter-terminal transmissions (e.g., SL transmissions) according to the inter-terminal priority (e.g., SL priority).

[0150] For example, when controlling the power of inter-terminal transmissions (e.g., SL transmissions) between different terminal-to-terminal communication carriers (e.g., SL communication carriers) and / or integrated inter-terminal communication carriers (e.g., integrated SL communication carriers), the minimum power of each inter-terminal transmission (e.g., SL transmission) (multiple) for each inter-terminal communication carrier (e.g., SL communication carrier) and / or inter-terminal resource pool (e.g., SL resource pool) can be (pre-set).

[0151] For example, if the power of inter-terminal transmissions (e.g., SL transmissions) is less than or equal to the minimum power, the terminal may omit the inter-terminal transmissions (e.g., SL transmissions) and / or re-select the transmission resources for the inter-terminal transmissions (e.g., SL transmissions).

[0152] For example, if the power for inter-terminal transmissions (e.g., SL transmissions) (multiple) can be guaranteed up to the minimum power, and the total power remains greater than the terminal's maximum transmission power even after reducing the power of lower-priority inter-terminal transmissions (e.g., SL transmissions) according to the inter-terminal priority (e.g., SL priority), the terminal can then reduce the power of the next lowest-priority inter-terminal transmission (e.g., SL transmission).

[0153] On the other hand, a terminal can simultaneously transmit multiple inter-terminal physical feedback channels (e.g., PSFCH) to an inter-terminal communication carrier (e.g., SL communication carrier), and the power control method for these may differ from the power control method for multiple inter-terminal physical channels (e.g., PSCCH / PSSCH) and / or inter-terminal synchronization signal blocks (e.g., S-SSB) on multiple inter-terminal communication carriers (e.g., SL communication carriers).

[0154] For example, a terminal can calculate the number of inter-terminal physical feedback channels (e.g., PSFCHs) and / or the power of inter-terminal physical feedback channels (e.g., PSFCHs) to be simultaneously transmitted to multiple inter-terminal communication carriers (e.g., SL communication carriers) and / or integrated inter-terminal communication carriers (e.g., integrated SL communication carriers).

[0155] For example, in the above, the transmission power of each inter-terminal physical feedback channel (e.g., PSFCH) may be the same for all different inter-terminal communication carriers (e.g., SL communication carriers) and / or integrated inter-terminal communication carriers (e.g., integrated SL communication carriers).

[0156] For example, the parameters related to the power of the inter-terminal physical feedback channel (e.g., dl-P0-PSFCH or dl-Alpha-PSFCH) may not be set to be the same between different inter-terminal communication carriers (e.g., SL communication carriers) and / or integrated inter-terminal communication carriers (e.g., integrated SL communication carriers), and / or the parameters related to the power of the inter-terminal physical feedback channel (e.g., dl-P0-PSFCH or dl-Alpha-PSFCH) may be set to be the same value.

[0157] For example, the number of simultaneous transmissions and / or power values ​​for inter-terminal physical feedback channel (e.g., PSFCH) transmissions are determined for each inter-terminal communication carrier (e.g., SL communication carrier) and / or an integrated inter-terminal communication carrier (e.g., an integrated SL communication carrier), and / or after the above process, if the total power of simultaneous inter-terminal physical feedback channel (e.g., PSFCH) transmissions for multiple inter-terminal communication carriers (e.g., SL communication carriers) and / or an integrated inter-terminal communication carrier (e.g., an integrated SL communication carrier) is greater than the terminal's maximum transmission power, the terminal may reduce the power of inter-terminal physical feedback channel (e.g., PSFCH) transmissions (multiple) for inter-terminal communication carriers (e.g., SL communication carriers) with higher priority values ​​and / or omit such transmissions, based on a standard inter-terminal priority value (e.g., SL priority value) for each inter-terminal communication carrier (e.g., SL communication carrier) and / or an integrated inter-terminal communication carrier (e.g., an integrated SL communication carrier).

[0158] For example, the aforementioned reference terminal priority value (e.g., SL priority value) may be the highest and / or lowest priority value for terminal-to-terminal physical feedback channel (e.g., PSFCH) transmissions that have been determined to be transmitted within the terminal-to-terminal communication carrier (e.g., SL communication carrier).

[0159] For example, in the omission of multiple inter-terminal physical feedback channel (e.g., PSFCH) transmissions for a specific inter-terminal communication carrier (e.g., SL communication carrier), all inter-terminal physical feedback channel (e.g., PSFCH) transmissions within the inter-terminal communication carrier (e.g., SL communication carrier) can be omitted, and / or transmissions with higher priority values ​​can be omitted first. For example, for inter-terminal communication carriers (e.g., SL communication carriers) with the same reference priority value, the inter-terminal communication carriers (e.g., SL communication carriers) whose transmission power is reduced or omitted are determined in order of highest to lowest carrier index, or as determined by the terminal.

[0160] Various embodiments of this disclosure can be applied differently to cases where the terminal-to-terminal integrated carrier (e.g., SL-integrated carrier) is an integrated contiguous carrier, an integrated non-contiguous carrier, an inter-band, or an intra-band carrier. In the aforementioned cases, the integrated terminal-to-terminal communication carrier (e.g., SL communication carrier) can be divided into multiple groups, and the power control method within each group and the power control method between groups can be extended in different ways.

[0161] On the other hand, the maximum transmit power of each terminal for each inter-terminal communication carrier (e.g., SL communication carrier) was determined based on the maximum transmit power value (pre-set) in the resource pool from which the inter-terminal physical channel (e.g., PSCCH / PSSCH) is transmitted in the case of an inter-terminal physical channel (e.g., PSCCH / PSSCH), determined independently of the maximum transmit power value (pre-set) in the resource pool for an inter-terminal synchronization signal block (e.g., S-SSB), and determined based on the sum of the maximum transmit power values ​​(pre-set) in the resource pools (multiple) from which the inter-terminal physical feedback channel (e.g., PSFCH) is transmitted in the case of simultaneous transmission of an inter-terminal physical feedback channel (e.g., PSFCH).

[0162] For example, the maximum transmit power of a terminal for multiple inter-terminal physical channel (e.g., PSCCH / PSSCH) transmissions to multiple integrated inter-terminal communication carriers (e.g., integrated SL communication carriers) can be determined based on the sum of the maximum transmit power values ​​(pre-configured) in the resource pool to which the simultaneously transmitted inter-terminal physical channels (e.g., PSCCH / PSSCH) belong.

[0163] For example, the maximum transmit power of a terminal for terminal-to-terminal physical feedback channel (PSFCH) transmissions (multiple) to multiple integrated terminal-to-terminal communication carriers (e.g., integrated SL communication carriers) can be determined based on the sum of the maximum transmit power values ​​(pre-set) in a resource pool for a single terminal-to-terminal communication carrier (e.g., SL communication carrier) to which the simultaneously transmitted terminal-to-terminal physical feedback channels (e.g., PSFCH) belong and / or for multiple terminal-to-terminal communication carriers (e.g., SL communication carriers).

[0164] For example, the terminal's UE capability (UE capability) for the maximum number of inter-terminal physical feedback channels (e.g., PSFCH) received and / or the maximum number of inter-terminal physical feedback channels (e.g., PSFCH) transmitted can be determined separately for each terminal, band, and / or band combination. For example, in the terminal's capability for the maximum number of inter-terminal physical feedback channels (e.g., PSFCH) received and / or the maximum number of inter-terminal physical feedback channels (e.g., PSFCH) transmitted, there may be separate values ​​for the inter-terminal communication carrier (e.g., SL communication carrier) and for the integrated inter-terminal communication carrier (e.g., integrated SL communication carrier) or for each terminal.

[0165] For example, a terminal can determine the target inter-terminal physical feedback channel (e.g., PSFCH) for each inter-terminal communication carrier (e.g., SL communication carrier) based on the number of first maximum inter-terminal physical feedback channels (e.g., PSFCH) received and / or the number of first maximum inter-terminal physical feedback channels (e.g., PSFCH) transmitted, and then finally determine the target inter-terminal physical feedback channel (e.g., PSFCH) for the aggregated inter-terminal communication carrier (e.g., aggregated SL communication carrier) based on the number of second maximum inter-terminal physical feedback channels (e.g., PSFCH) received and / or the number of second maximum inter-terminal physical feedback channels (e.g., PSFCH) transmitted.

[0166] According to one embodiment of the present disclosure, a terminal can determine whether to transmit or receive an inter-terminal physical feedback channel (e.g., PSFCH) based on the (reference) priority value of the inter-terminal physical feedback channel (e.g., PSFCH) for each inter-terminal communication carrier (e.g., SL communication carrier).

[0167] Thereafter, for example, a terminal can ultimately select to transmit or receive an inter-terminal physical feedback channel (e.g., PSFCH) for an integrated inter-terminal communication carrier (e.g., integrated SL communication carrier) for an integrated inter-terminal physical feedback channel (e.g., PSFCH), based on the inter-terminal physical feedback channel (e.g., PSFCH) transmission or reception determined separately for each inter-terminal communication carrier (e.g., SL communication carrier).

[0168] For example, the operation of selecting whether to transmit or receive an inter-terminal physical feedback channel (e.g., PSFCH) for a plurality of integrated inter-terminal communication carriers (e.g., integrated SL communication carriers) can follow the number of inter-terminal physical feedback channel (e.g., PSFCH) transmissions and receptions determined separately for each inter-terminal communication carrier (e.g., SL communication carrier).

[0169] For example, if there are many carriers for which inter-terminal physical feedback channel (PSFCH) transmission (or inter-terminal physical feedback channel (PSFCH) reception) has been selected for inter-terminal communication carriers (e.g., SL communication carriers), the terminal can select inter-terminal physical feedback channel (PSFCH) transmission operation (or inter-terminal physical feedback channel (PSFCH) reception operation) for the aggregated inter-terminal communication carriers (e.g., aggregated SL communication carriers).

[0170] For example, if the number of carriers selected for inter-terminal physical feedback channel (e.g., PSFCH) transmission is the same as the number of carriers selected for inter-terminal physical feedback channel (e.g., PSFCH) reception, the operation of either inter-terminal physical feedback channel (e.g., PSFCH) transmission or inter-terminal physical feedback channel (e.g., PSFCH) reception can be selected according to the terminal implementation.

[0171] For example, a terminal can compare the smallest reference priority value for transmitting an inter-terminal physical feedback channel (e.g., PSFCH) with respect to an integrated inter-terminal communication carrier (e.g., integrated SL communication carrier), and the smallest reference priority value for receiving an inter-terminal physical feedback channel (e.g., PSFCH), and perform the action corresponding to the smaller value.

[0172] For example, if the number of inter-terminal physical feedback channel (e.g., PSFCH) transmissions is above or exceeds a certain level (e.g., a (pre-set) value) for an integrated inter-terminal communication carrier (e.g., an integrated SL communication carrier), the terminal may prioritize inter-terminal physical feedback channel (e.g., PSFCH) transmission over inter-terminal physical feedback channel (e.g., PSFCH) reception.

[0173] According to one embodiment of the present disclosure, if the priority value for receiving an inter-terminal physical feedback channel (e.g., PSFCH) with respect to an integrated inter-terminal communication carrier (e.g., integrated SL communication carrier) is less than or equal to a threshold set (in advance) and / or via PC5-RRC, the terminal can set the priority for receiving an inter-terminal physical feedback channel (e.g., PSFCH) higher than the priority for receiving an inter-terminal physical feedback channel (e.g., PSFCH) when there is a collision between transmitting and receiving an inter-terminal physical feedback channel (e.g., PSFCH).

[0174] For example, the process may be executed before and / or after comparing the inter-terminal priority values ​​(e.g., SL priority values) for inter-terminal physical feedback channel (e.g., PSFCH) transmission and inter-terminal physical feedback channel (e.g., PSFCH) reception.

[0175] For example, the process can be executed if the reference priority value for terminal-to-terminal physical feedback channel (e.g., PSFCH) transmission and the reference priority value for terminal-to-terminal physical feedback channel (e.g., PSFCH) reception are the same.

[0176] According to one embodiment of the present disclosure, if an inter-terminal physical feedback channel (e.g., PSFCH) reception exists for a specific inter-terminal communication carrier (e.g., SL communication carrier) among the aggregated inter-terminal communication carriers (e.g., aggregated SL communication carriers), and if the inter-terminal physical feedback channel (e.g., PSFCH) reception corresponds to a unicast inter-terminal physical shared channel (e.g., PSSCH), and / or if a terminal determines a radio link failure (e.g., RLF) based on unicast inter-terminal feedback (e.g., SL HARQ-ACK feedback), the terminal can set a higher priority for inter-terminal physical feedback channel (e.g., PSFCH) reception than for inter-terminal physical feedback channel (e.g., PSFCH) transmission with respect to the aggregated inter-terminal communication carrier (e.g., aggregated SL communication carrier).

[0177] For example, the process can be performed before and / or after comparing the inter-terminal priority values ​​(e.g., SL priority values) for inter-terminal physical feedback channel (e.g., PSFCH) transmission and inter-terminal physical feedback channel (e.g., PSFCH) reception.

[0178] For example, the process can be executed if the reference priority value for terminal-to-terminal physical feedback channel (e.g., PSFCH) transmission and the reference priority value for terminal-to-terminal physical feedback channel (e.g., PSFCH) reception are the same. For example, the specific terminal-to-terminal communication carrier (e.g., SL communication carrier) can be (pre)configured and / or configured via PC5-RRC.

[0179] According to one embodiment of the present disclosure, if a terminal has inter-terminal physical feedback channel (eg, PSFCH) transmissions on a specific inter-terminal communication carrier (eg, SL communication carrier) among the aggregated inter-terminal communication carriers (eg, aggregated SL communication carriers), and if the inter-terminal physical feedback channel (eg, PSFCH) transmission corresponds to a unicast inter-terminal physical shared channel (eg, PSSCH), and / or if a terminal (receiving the inter-terminal physical feedback channel (eg, PSFCH)) determines a radio link failure (eg, RLF) based on unicast inter-terminal feedback (eg, SL HARQ-ACK feedback), the terminal can set a higher priority for inter-terminal physical feedback channel (eg, PSFCH) transmissions on the aggregated inter-terminal communication carriers (eg, aggregated SL communication carriers) than for inter-terminal physical feedback channel (eg, PSFCH) reception.

[0180] For example, the process can be performed before and / or after comparing inter-terminal priority values ​​(e.g., SL priority values) for inter-terminal physical feedback channel (e.g., PSFCH) transmission and inter-terminal physical feedback channel (e.g., PSFCH) reception.

[0181] For example, the process can be executed if the reference priority value for terminal-to-terminal physical feedback channel (e.g., PSFCH) transmission and the reference priority value for terminal-to-terminal physical feedback channel (e.g., PSFCH) reception are the same. For example, the specific terminal-to-terminal communication carrier (e.g., SL communication carrier) can be (pre)configured and / or configured via PC5-RRC.

[0182] According to one embodiment of the present disclosure, the priority settings for unicast inter-terminal physical feedback channel (e.g., PSFCH) transmission and unicast inter-terminal physical feedback channel (e.g., PSFCH) reception on the same unicast link can be (pre) configured on a terminal-by-terminal and / or the same between terminals, and / or can be configured via PC5-RRC.

[0183] For example, in a unicast link between terminal 1 and terminal 2, the priority for receiving the unicast inter-terminal physical feedback channel (e.g., PSFCH) is set higher for terminal 1 than the priority for transmitting the (unicast) inter-terminal physical feedback channel (e.g., PSFCH), and the priority for transmitting the unicast inter-terminal physical feedback channel (e.g., PSFCH) is set higher for terminal 2 than the priority for receiving the (unicast) inter-terminal physical feedback channel (e.g., PSFCH). This allows terminal 1 to efficiently perform a unicast inter-terminal feedback (e.g., SL HARQ-ACK feedback) based radio link failure (e.g., RLF) declaration.

[0184] Various embodiments of this disclosure can be applied differently depending on the presence or absence of the inter-terminal feedback (e.g., SL HARQ-ACK feedback) option and / or the level of congestion control.

[0185] On the other hand, when controlling the power of inter-terminal transmissions (e.g., SL transmissions) between different inter-terminal communication carriers (e.g., SL communication carriers) and / or integrated inter-terminal communication carriers (e.g., integrated SL communication carriers), if the total power is greater than the terminal's maximum transmission power, the terminal can reduce the power of lower-priority inter-terminal transmissions (e.g., SL transmissions) according to the inter-terminal priority (e.g., SL priority).

[0186] On the other hand, a terminal can perform terminal-to-base station transmission (e.g., UL transmission) via multiple terminal-to-base station (e.g., UL) carriers, and simultaneously perform terminal-to-terminal transmission (e.g., SL transmission) via multiple terminal-to-terminal communication carriers (e.g., SL communication carriers).

[0187] For example, when simultaneously transmitting terminal-to-terminal communication (e.g., SL communication) and terminal-to-base station communication (e.g., UL communication) over multiple carriers, if the total transmission power exceeds the terminal's maximum transmission power, and / or if terminal-to-terminal transmissions (e.g., SL transmissions) on all terminal-to-terminal communication carriers (e.g., SL communication carriers) have a higher priority than terminal-to-base station transmissions (e.g., UL transmissions) on all terminal-to-base station carriers (e.g., UL transmissions), the terminal can reduce the transmission power of all or part of the terminal-to-base station transmissions (e.g., UL transmissions) on the terminal-to-base station carriers so that the total transmission power is less than or equal to the terminal's maximum transmission power.

[0188] For example, when simultaneously transmitting terminal-to-terminal communication (e.g., SL communication) and terminal-to-base station communication (e.g., UL communication) over multiple carriers, if the total transmission power exceeds the terminal's maximum transmission power, and / or if terminal-to-terminal transmission (e.g., SL transmission) on at least one terminal-to-terminal communication carrier (e.g., SL communication carrier) has a higher priority than terminal-to-base station transmission (e.g., UL transmission) on all terminal-to-base station carriers, the terminal can reduce the transmission power of all or part of the terminal-to-base station transmissions (e.g., UL transmissions) on the terminal-to-base station carriers so that the total transmission power is less than or equal to the terminal's maximum transmission power.

[0189] For example, when simultaneously transmitting terminal-to-terminal communication (e.g., SL communication) and terminal-to-base station communication (e.g., UL communication) over multiple carriers, if the total transmission power exceeds the terminal's maximum transmission power, and / or if terminal-to-terminal transmissions (e.g., SL transmissions) of all terminal-to-terminal communication carriers (e.g., SL communication carriers) have a higher priority than terminal-to-base station transmissions (e.g., UL transmissions) of at least one terminal-to-base station carrier, the terminal can reduce the transmission power of all or part of the terminal-to-base station transmissions (e.g., UL transmissions) of the terminal-to-base station carriers so that the total transmission power is less than or equal to the terminal's maximum transmission power.

[0190] For example, when simultaneously transmitting terminal-to-terminal communication (e.g., SL communication) and terminal-to-base station communication (e.g., UL communication) over multiple carriers, if the total transmission power exceeds the terminal's maximum transmission power, and / or if terminal-to-terminal transmission (e.g., SL transmission) on at least one terminal-to-terminal communication carrier (e.g., SL communication carrier) has a higher priority than terminal-to-base station transmission (e.g., UL transmission) on at least one terminal-to-base station carrier (e.g., UL transmission), the terminal can reduce the transmission power of all or part of the terminal-to-base station transmissions (e.g., UL transmissions) on the terminal-to-base station carrier so that the total transmission power is less than or equal to the terminal's maximum transmission power.

[0191] For example, the above operation can be performed by comparing the priority of terminal-to-base station transmissions (e.g., UL transmissions) to terminal-to-base station (e.g., UL) carriers (multiple) based on a representative priority value (e.g., minimum or maximum value) for all integrated terminal-to-terminal communication carriers (e.g., integrated SL communication carriers).

[0192] For example, when simultaneously transmitting terminal-to-terminal communication (e.g., SL communication) and terminal-to-base station communication (e.g., UL communication) over multiple carriers, if the total transmission power exceeds the terminal's maximum transmission power, and / or if terminal-to-base station transmissions (e.g., UL transmissions) on at least one terminal-to-base station (e.g., UL) carrier have a higher priority than terminal-to-terminal transmissions (e.g., SL transmissions) on at least one terminal-to-terminal communication carrier (e.g., SL communication carrier), the terminal can reduce the transmission power of all or part of the terminal-to-terminal transmissions (e.g., SL transmissions) on the terminal-to-terminal communication carrier (e.g., SL communication carrier) so that the total transmission power is less than or equal to the terminal's maximum transmission power.

[0193] For example, when simultaneously transmitting terminal-to-terminal communication (e.g., SL communication) and terminal-to-base station communication (e.g., UL communication) over multiple carriers, if the total transmission power exceeds the terminal's maximum transmission power, and / or if terminal-to-base station transmissions (e.g., UL transmissions) on at least one terminal-to-base station carrier have a higher priority than terminal-to-terminal transmissions (e.g., SL transmissions) on all terminal-to-terminal carriers (e.g., SL communication carriers), the terminal can reduce the transmission power of all or part of the terminal-to-terminal transmissions (e.g., SL transmissions) on the terminal-to-terminal carriers (e.g., SL communication carriers) so that the total transmission power is less than or equal to the terminal's maximum transmission power.

[0194] For example, when simultaneously transmitting terminal-to-terminal communication (e.g., SL communication) and terminal-to-base station communication (e.g., UL communication) over multiple carriers, if the total transmission power exceeds the terminal's maximum transmission power, and / or if terminal-to-base station transmissions (e.g., UL transmissions) on all terminal-to-base station (e.g., UL transmissions) have a higher priority than terminal-to-terminal transmissions (e.g., SL transmissions) on at least one terminal-to-terminal communication carrier (e.g., SL communication carrier), the terminal can reduce the transmission power of all or part of the terminal-to-terminal transmissions (e.g., SL transmissions) on the terminal-to-terminal communication carrier (e.g., SL communication carrier) so that the total transmission power is less than or equal to the terminal's maximum transmission power.

[0195] For example, when simultaneously transmitting terminal-to-terminal communication (e.g., SL communication) and terminal-to-base station communication (e.g., UL communication) over multiple carriers, if the total transmission power exceeds the terminal's maximum transmission power, and / or if terminal-to-base station transmissions (e.g., UL transmissions) on all terminal-to-base station carriers have a higher priority than terminal-to-terminal transmissions (e.g., SL transmissions) on all terminal-to-terminal carriers (e.g., SL communication carriers), the terminal can reduce the transmission power of all or part of the terminal-to-terminal transmissions (e.g., SL transmissions) on the terminal-to-terminal carriers (e.g., SL communication carriers) so that the total transmission power is less than or equal to the terminal's maximum transmission power.

[0196] For example, when a terminal simultaneously transmits terminal-to-terminal communication (e.g., SL communication) and terminal-to-base station communication (e.g., UL communication) for multiple carriers, if the total transmission power exceeds the terminal's maximum transmission power, the terminal can set the priority in descending order in the following sequence: i) terminal-to-terminal communication carriers (e.g., SL communication carriers) (multiple) whose terminal-to-terminal transmissions (e.g., SL transmissions) have a higher priority than all terminal-to-base station (e.g., UL transmissions) for all terminal-to-base station (e.g., UL transmissions), ii) terminal-to-base station (e.g., UL) carriers (multiple), iii) other terminal-to-terminal communication carriers (e.g., SL communication carriers) (including terminal-to-terminal transmissions (e.g., SL transmissions) (multiple) whose priority is not higher than the priority of all terminal-to-base station (e.g., UL) carriers) (multiple). Then, the terminal can reduce the transmission power of the carriers (multiple) with lower priority so that the total transmission power remains below the terminal's maximum transmission power.

[0197] From this point forward, for example, the other terminal-to-terminal communication carriers (e.g., SL communication carriers) (multiple) can be divided into terminal-to-terminal communication carriers (e.g., SL communication carriers) (multiple) whose terminal-to-terminal transmissions (e.g., SL transmissions) are of higher priority than terminal-to-base station transmissions (e.g., UL transmissions) of at least one terminal-to-base station (e.g., UL) carrier, and terminal-to-terminal communication carriers (e.g., SL communication carriers) (multiple) whose terminal-to-base station transmissions (e.g., UL transmissions) are of lower priority than terminal-to-base station transmissions (e.g., UL transmissions) of a terminal-to-base station (e.g., UL) carrier that includes terminal-to-terminal transmissions (e.g., SL transmissions), and from this point forward, the priority can also be distinguished in descending order.

[0198] For example, when a terminal is simultaneously transmitting terminal-to-terminal communication (e.g., SL communication) and terminal-to-base station (e.g., UL) signals to multiple carriers, if the total transmission power exceeds the terminal's maximum transmission power, and / or if the number of terminal-to-terminal communication carriers (e.g., SL communication carriers) (multiple) that have a higher priority than all terminal-to-base station (e.g., UL) transmissions of terminal-to-base station (e.g., UL) carriers exceeds a certain level, the terminal may reduce the transmission power of all or part of the terminal-to-base station (e.g., UL) transmissions of the terminal-to-base station (e.g., UL) carriers so that the total transmission power is less than or equal to the terminal's maximum transmission power.

[0199] For example, when terminal-to-terminal communication (e.g., SL communication) and terminal-to-base station (e.g., UL) are simultaneously transmitted over multiple carriers, if the total transmission power exceeds the terminal's maximum transmission power, and / or if the number of terminal-to-terminal communication carriers (e.g., SL communication carriers) (multiple) that have a higher priority than all terminal-to-base station (e.g., UL) carrier transmissions (e.g., UL transmissions) among the terminal-to-terminal communication carriers (e.g., SL communication carriers) is below or less than a certain level, the terminal can reduce the transmission power of all or some of the terminal-to-terminal transmissions (e.g., SL transmissions) of the terminal-to-terminal communication carriers (e.g., SL communication carriers) so that the total transmission power is less than or equal to the terminal's maximum transmission power.

[0200] For example, the certain level may be a (pre-)set value, a value set via PC5-RRC, the number of terminal-to-terminal communication carriers (e.g., SL communication carriers) (multiple) that have a lower priority than at least one terminal-to-base station (e.g., UL) carrier's terminal-to-base station transmission (e.g., UL transmission), and / or the sum of the above combinations.

[0201] For example, in certain situations (e.g., situations where priority is not specified for terminal-to-terminal communication carriers (e.g., SL communication carriers) (multiple) and terminal-to-base station (e.g., UL) carriers (multiple)), a terminal may reduce its transmit power to all or part of the terminal-to-terminal communication carriers (e.g., SL communication carriers) (multiple) and / or all or part of the terminal-to-base station (e.g., UL) carriers (multiple) so that the total transmit power is less than or equal to the terminal's maximum transmit power.

[0202] In various embodiments of this disclosure, a method for reducing the transmission power for inter-terminal transmissions (e.g., SL transmissions) of multiple inter-terminal communication carriers (e.g., SL communication carriers) may involve preferentially reducing the transmission power of lower-priority inter-terminal transmissions (e.g., SL transmissions) or inter-terminal communication carriers (e.g., SL communication carriers), and / or reducing them at the same rate (equal scaling).

[0203] In various embodiments of this disclosure, a method for reducing the transmit power for terminal-to-base station (e.g., UL) carriers of multiple terminal-to-base station (e.g., UL) carriers may involve preferentially reducing the transmit power of lower-priority terminal-to-base station (e.g., UL) carriers or / or reducing them at an equal scaling rate.

[0204] In various embodiments of this disclosure, the priority between terminal-to-terminal transmissions (e.g., SL transmissions) of one terminal-to-terminal carrier (e.g., SL carrier) and terminal-to-base station transmissions (e.g., UL transmissions) of another terminal-to-terminal carrier (e.g., SL carrier) can be determined by the priority value for terminal-to-terminal transmissions (e.g., SL transmissions), the terminal-to-terminal priority (e.g., SL priority) threshold for eMBB terminal-to-base station transmissions (e.g., UL transmissions) and terminal-to-terminal transmissions (e.g., SL transmissions), the presence and value of the terminal-to-terminal priority (e.g., SL priority) threshold for URLLC terminal-to-base station transmissions (e.g., UL transmissions) and terminal-to-terminal transmissions (e.g., SL transmissions), the type of terminal-to-terminal channel (e.g., SL channel), and / or the type of terminal-to-base station (e.g., UL) channel.

[0205] In various embodiments of this disclosure, the determination of priority between terminal-to-terminal transmissions (e.g., SL transmissions) of one terminal-to-terminal carrier (e.g., SL carrier) and terminal-to-base station transmissions (e.g., UL transmissions) of another terminal-to-terminal carrier (e.g., SL carrier) can also operate when multiple terminal-to-terminal transmissions (e.g., SL transmissions) overlap with a single terminal-to-base station transmission (e.g., UL transmission) and / or when multiple terminal-to-base station transmissions (e.g., UL transmissions) overlap with a single terminal-to-terminal transmission (e.g., SL transmission), in which case the idea of ​​this disclosure is extended and applied and / or the terminal processing time determines which of the overlapping transmissions has higher priority, terminal-to-terminal communication (e.g., SL communication) or terminal-to-base station communication (e.g., UL communication).

[0206] For example, in the case of terminal-to-terminal transmission (e.g., SL transmission), if all duplicate terminal-to-base station transmissions (e.g., UL transmission) detected by terminal processing time are judged to have high priority, then terminal-to-terminal transmission (e.g., SL transmission) may have high priority, while all other terminal-to-base station transmissions (e.g., UL transmission) may have higher priority.

[0207] For example, in the case of terminal-to-base station transmission (e.g., UL transmission), if the terminal processing time determines that at least one duplicate terminal-to-base station transmission (e.g., SL transmission) has a higher priority than the other terminal-to-base station transmission (e.g., SL transmission), then terminal-to-base station transmissions (e.g., UL transmissions) may have a higher priority, while all other terminal-to-base station transmissions (e.g., SL transmissions) may have a higher priority.

[0208] In various embodiments of this disclosure, the transmission power modification operation for terminal-to-base station (e.g., UL) carriers and terminal-to-terminal communication carriers (e.g., SL communication carriers) can be performed when the total power exceeds the maximum transmission power value of the terminal, after the completion of the power control operation between terminal-to-base station (e.g., UL) carriers and / or after the completion of the power control operation between terminal-to-terminal communication carriers (e.g., SL communication carriers) when the total power exceeds the maximum transmission power value of the terminal.

[0209] In various embodiments of this disclosure, the transmission power modification operation for terminal-to-base station (e.g., UL) carriers and terminal-to-terminal communication carriers (e.g., SL communication carriers) can be performed before the power control operation is performed between terminal-to-base station (e.g., UL) carriers when the total power exceeds the maximum transmission power value of the terminals, and / or before the power control operation is performed between terminal-to-terminal communication carriers (e.g., SL communication carriers) when the total power exceeds the maximum transmission power value of the terminals.

[0210] Various embodiments of this disclosure can be applied in different combinations depending on the inter-terminal communication carrier (e.g., SL communication carrier), inter-terminal band (e.g., SL band), inter-terminal integrated carrier (e.g., SL integrated carrier) combination, and / or inter-terminal band (e.g., SL band) combination.

[0211] Various embodiments of the present disclosure can be applied in combinations such as the above, depending on the form of carrier integration (e.g., integration of adjacent carriers or non-adjacent carriers and / or intraband or interband).

[0212] The priority comparison, transmission omission, and / or power reduction between terminal-to-terminal communication carriers (e.g., SL communication carriers) and terminal-to-base station (e.g., UL) carriers described herein can also be extended to transmission omission and / or reception omission related to terminal capabilities.

[0213] Embodiments of the present disclosure may differ and / or be (pre-configured) for resource pools, transmissions outside and / or inside resource pools, quality of service (e.g., QoS) parameters, CAPC, inter-terminal priority (e.g., SL priority), inter-terminal channel (e.g., SL channel) type, inter-terminal partial bandwidth (e.g., SL BWP), inter-terminal communication carrier (e.g., SL communication carrier), congestion control level, transmit or receive operation, transmit power level, transmit start time, cast type, enable or disable inter-terminal feedback (e.g., SL HARQ-ACK feedback), positive feedback related (e.g., HARQ-ACK feedback) options, and / or the number of attempts to transmit the same information or TB.

[0214] For example, in various embodiments of this disclosure, (pre-configuration) operations can be performed for each resource pool, transmissions outside and / or inside the resource pool, quality of service (e.g., QoS) parameters, inter-terminal priority (e.g., SL priority), inter-terminal channel (e.g., SL channel) type, inter-terminal partial bandwidth (e.g., SL BWP), inter-terminal communication carrier (e.g., SL communication carrier), congestion control level, transmit or receive operation, transmit power level, transmit start time, cast type, enable or disable inter-terminal feedback (e.g., SL HARQ-ACK feedback), positive feedback related (e.g., HARQ-ACK feedback) options, and / or the number of attempts to transmit the same information or transmit block (e.g., TB).

[0215] The proposed method can be applied to the apparatus described below. First, the receiving terminal's processor 202 can set at least one partial bandwidth (e.g., BWP). Then, the receiving terminal's transceiver 206 can control the receiving terminal's transceiver 206 to receive inter-terminal physical channel (e.g., PSCCH / PSCH) and / or inter-terminal communication (e.g., SL communication) related reference signals from the transmitting terminal over at least one partial bandwidth (e.g., BWP).

[0216] Data speed can be increased and network capacity increased by increasing bandwidth through aggregation between different carriers. However, if the temporal positions of terminal-to-terminal physical feedback channel (e.g., PSFCH) resources do not coincide or match between different carriers, or if the positions of available symbols related to terminal-to-terminal communication (e.g., SL communication) do not coincide or match, an automatic gain control (AGC) problem may occur during terminal transmission.

[0217] According to various embodiments of this disclosure, aggregated SL carriers used in terminal-to-terminal communication can be configured such that the start, length, cyclic substitution (e.g., CP), and / or subcarrier interval (e.g., SCS) of the active symbols related to terminal-to-terminal communication (e.g., SL communication) are the same. Alternatively, for example, a terminal can be configured such that the start, length, cyclic substitution (e.g., CP), and / or subcarrier interval (e.g., SCS) of all (or some) of the carriers included in the aggregated carrier are the same.

[0218] When carrier integration according to various embodiments of this disclosure is used, the automatic gain control problem related to inter-terminal physical channel (e.g., PSCCH / PSSCH) transmission that may occur between different inter-terminal carriers can be resolved. Furthermore, according to various embodiments of this disclosure, the inter-terminal physical feedback channel resource period can be set independently for each inter-terminal carrier, and at the same time, the automatic gain control problem related to inter-terminal physical channel (e.g., PSCCH / PSSCH) transmission that may occur between different carriers depending on the location of the inter-terminal physical feedback channel (e.g., PSFCH) resource can be resolved.

[0219] Figure 11 illustrates a procedure in which a first device performs wireless communication according to one embodiment of the present disclosure. The embodiment in Figure 11 can be combined with various embodiments of the present disclosure.

[0220] Referring to Figure 11, in step S1110, the first device can acquire information about the integrated carrier wave. In step S1120, the first device can use the integrated carrier wave to perform inter-device transmission to the second device. For example, the integrated carrier wave may include a first carrier wave and a second carrier wave, and the first information for symbols usable for inter-device communication included in the first carrier wave is expected to be set in the same way as the second information for symbols usable for inter-device communication included in the second carrier wave.

[0221] For example, the first piece of information can be set in the same way as the second piece of information.

[0222] For example, the first carrier wave and the second carrier wave can be expected to be configured to have time resource alignment.

[0223] For example, being configured to have a time resource alignment may include the first information and the second information being the same.

[0224] For example, the first information may include information relating to at least one inter-device valid symbol.

[0225] For example, the information relating to the at least one inter-device valid symbol may include information relating to the number of the at least one inter-device valid symbol or information relating to the position of the last symbol among the at least one inter-device valid symbol.

[0226] For example, the first information may include information regarding the position within the slot of the inter-device physical feedback slot.

[0227] For example, based on the setting of the first information in the same way as the second information, the position in the slot of the first inter-device physical feedback channel symbol associated with the first carrier wave may be the same as the position in the slot of the second inter-device physical feedback channel symbol associated with the second carrier wave.

[0228] For example, the first inter-device physical feedback channel symbol associated with the first carrier wave may not overlap with the inter-device transmit slot associated with the second carrier wave.

[0229] For example, the third information related to the first carrier wave can be expected to be set in the same way as the fourth information related to the second carrier wave.

[0230] For example, the third information may include at least one of the following: information relating to numerology, information relating to subcarrier intervals, or information relating to cyclic prefixes.

[0231] For example, the third information includes information relating to the time-domain location of an inter-device synchronization signal block resource, and the time-domain location of the first inter-device synchronization signal block resource associated with the first carrier wave may be the same as the time-domain location of the second inter-terminal synchronization signal block resource associated with the second carrier wave.

[0232] For example, the third information includes information regarding the minimum interval between inter-device physical sharing channels and inter-device physical feedback channels, and the first minimum time interval between the inter-device physical sharing channels and inter-device physical feedback channels related to the first carrier wave may be the same as the second minimum time interval between the inter-device physical sharing channels and inter-device physical feedback channels related to the second carrier wave.

[0233] The embodiments described above can be applied to various devices described below. For example, the processor 102 of the first device 100 can acquire information about an integrated carrier wave. The processor 102 of the first device 100 can then control the transceiver 106 to perform inter-device transmission to the second device 200 using the integrated carrier wave. For example, the integrated carrier wave may include a first carrier wave and a second carrier wave, and the first information for symbols usable for inter-device communication included in the first carrier wave is expected to be set in the same way as the second information for symbols usable for inter-device communication included in the second carrier wave.

[0234] According to one embodiment of the present disclosure, a first device for performing wireless communication is provided. For example, the first device may include: at least one transceiver; at least one processor; and at least one memory connected to the at least one processor and recording instructions causing the first device to perform an operation based on that operation being performed by the at least one processor. For example, the operation may include: acquiring information about an aggregated carrier; and performing an inter-device transmission to a second device using the aggregated carrier, wherein the aggregated carrier includes a first carrier and a second carrier, and the first information for symbols available for inter-device communication included in the first carrier is expected to be set in the same way as the second information for symbols available for inter-device communication included in the second carrier.

[0235] For example, the first piece of information can be set in the same way as the second piece of information.

[0236] For example, the first carrier wave and the second carrier wave can be expected to be configured to have time resource alignment.

[0237] For example, being configured to have a time resource alignment may include the first information and the second information being the same.

[0238] For example, the first information may include information relating to at least one inter-device valid symbol.

[0239] For example, the information for the at least one inter-device valid symbol may include information about the number of the at least one inter-device valid symbols or information about the position of the last symbol among the at least one inter-device valid symbols.

[0240] For example, the first information may include information regarding the position within the slot of the inter-device physical feedback slot.

[0241] For example, based on the fact that the first information is set in the same way as the second information, the position in the slot of the first inter-device physical feedback channel symbol associated with the first carrier wave may be the same as the position in the slot of the second inter-device physical feedback channel symbol associated with the second carrier wave.

[0242] For example, the first inter-device physical feedback channel symbol associated with the first carrier wave may not overlap with the inter-device transmit slot associated with the second carrier wave.

[0243] For example, the third information related to the first carrier wave can be expected to be set in the same way as the fourth information related to the second carrier wave.

[0244] For example, the third information may include at least one of the following: information relating to numerology, information relating to subcarrier intervals, or information relating to cyclic prefixes.

[0245] For example, the third information includes information relating to the time-domain location of an inter-device synchronization signal block resource, and the time-domain location of the first inter-device synchronization signal block resource associated with the first carrier wave may be the same as the time-domain location of the second inter-terminal synchronization signal block resource associated with the second carrier wave.

[0246] For example, the third information includes information regarding the minimum interval between inter-device physical sharing channels and inter-device physical feedback channels, and the first minimum time interval between the inter-device physical sharing channels and inter-device physical feedback channels related to the first carrier wave may be the same as the second minimum time interval between the inter-device physical sharing channels and inter-device physical feedback channels related to the second carrier wave.

For example, the device may include: at least one processor; and at least one memory connected to the at least one processor and recording instructions causing the first terminal to perform an operation based on that operation is performed by the at least one processor. For example, the operation may include: obtaining information about an aggregated carrier; and performing an inter-UE transmission to a second terminal using the aggregated carrier, wherein the aggregated carrier includes a first carrier and a second carrier, and the first information for symbols available for inter-UE communication included in the first carrier is expected to be set in the same way as the second information for symbols available for inter-UE communication included in the second carrier.

[0248] According to one embodiment of the present disclosure, a non-temporary computer-readable storage medium is provided which records instructions. For example, when executed, the instructions cause a first device to: obtain information about an aggregated carrier wave; and to perform an inter-device transmission to a second device using the aggregated carrier wave, wherein the aggregated carrier wave includes a first carrier wave and a second carrier wave, and it is expected that first information for symbols usable for inter-device communication included in the first carrier wave is set to be the same as second information for symbols usable for inter-device communication included in the second carrier wave.

For example, the integrated carrier wave may include a first carrier wave and a second carrier wave, and the first information for symbols usable for inter-device communication included in the first carrier wave is expected to be set in the same way as the second information for symbols usable for inter-device communication included in the second carrier wave.

[0272] Figure 15 shows a signal processing circuit for a transmitted signal according to one embodiment of the present disclosure. The embodiment in Figure 15 can be combined with various embodiments of the present disclosure.

[0273] Referring to Figure 15, 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. However, it is not limited to these, and the operation / function of Figure 15 can be performed by the processors 102, 202 and / or transceivers 106, 206 of Figure 14. The hardware elements of Figure 15 can be embodied by the processors 102, 202 and / or transceivers 106, 206 of Figure 14. For example, blocks 1010-1060 can be embodied by the processors 102, 202 of Figure 14. Also, blocks 1010-1050 can be embodied by the processors 102, 202 of Figure 14, and block 1060 can be embodied by the transceivers 106, 206 of Figure 14.

[0274] The codeword can be converted into a radio signal via the signal processing circuit 1000 in Figure 15. Here, the codeword is an encoded bit sequence of information blocks. The information blocks may include transmit blocks (e.g., UL-SCH transmit block, DL-SCH transmit block). The radio signal can be transmitted via various physical channels (e.g., PUSCH, PDSCH).

[0275] Specifically, the codeword can be converted into a bit sequence scrambled by the scrambler 1010. The scrambling sequence used for scrambling is generated based on an initialization value, which can include the ID information of the wireless device, etc. The scrambled bit sequence can be modulated into a modulation symbol sequence by the modulator 1020. The modulation method can 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 the layer mapper 1030. The modulation symbols of each transmission layer can be mapped to the corresponding antenna port(s) by the precoder 1040 (precoding). The output z of the precoder 1040 is obtained by multiplying the output y of the layer mapper 1030 by the N*M precoding matrix W. 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 a transform precoding (e.g., DFT transform) on the complex modulation symbol. Also, the precoder 1040 can perform precoding without performing transform precoding.

[0276] The resource mapper 1050 can map the modulated symbols of each antenna port to time-frequency resources. The time-frequency resources can include a plurality of symbols in the time domain (e.g., CP-OFDMA symbols, DFT-s-OFDMA symbols) and can include a plurality of subcarriers in the frequency domain. The signal generator 1060 generates a radio signal from the mapped modulated symbols, and the generated radio signal can be transmitted to other devices via each antenna. For this purpose, the signal generator 1060 can include an IFFT (Inverse Fast Fourier Transform) module, a CP (Cyclic Prefix) inserter, a DAC (Digital-to-Analog Converter), a frequency uplink converter, etc.

[0277] In a wireless device, the signal processing process for the received signal can be configured to be the reverse of the signal processing processes 1010 to 1060 in FIG. 15. For example, a wireless device (e.g., 100, 200 in FIG. 14) can receive a radio signal from the outside via an antenna port / transceiver. The received radio signal can be converted into a baseband signal via a signal restorer. For this purpose, the signal restorer can include a frequency downlink converter, an ADC (analog-to-digital converter), a CP remover, an FFT (Fast Fourier Transform) 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 codeword can be restored to the original information block through decoding. Therefore, the signal processing circuit (not shown) for the received signal can include a signal restorer, a resource demapper, a postcoder, a demodulator, a descrambler, and a decoder.
