Abstract
Description
Technical Field
[0001] This manual relates to mobile communications. Background Technology
[0002] The 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) is a technology for achieving high-speed packet communication. Many proposals have been put forward for LTE goals, including those aimed at reducing user and vendor costs, improving service quality, and expanding and increasing coverage and system capacity. 3GPP LTE requires lower cost per bit, increased service availability, flexible use of frequency bands, a simple architecture, open interfaces, and sufficient power consumption in terminals as upper-layer requirements.
[0003] Requirements and specifications for New Radio (NR) systems have begun to be developed within the International Telecommunication Union (ITU) and 3GPP. 3GPP must identify and develop technical components that will be successfully standardized in the new RAT to meet both pressing market demands and the longer-term requirements outlined in the ITU Radiocommunication Sector (ITU-R) International Mobile Telecommunications (IMT)-2020 process. Furthermore, NR should be able to utilize any spectrum band within at least 100 GHz that can be used for wireless communication even in the more distant future.
[0004] The goal of NR is to address all use cases, requirements, and deployment scenarios with a single technology framework, including enhanced mobile broadband (eMBB), massive machine-type communications (mMTC), ultra-reliable and low-latency communications (URLLC), and more. NR should be inherently backward compatible.
[0005] In 5G NR, terminals can apply maximum output power requirements (or requirements) to determine transmit power. For example, the maximum output power requirement can be a maximum power reduction (MPR) value.
[0006] Power level refers to the maximum power of all transmission bandwidths within the channel bandwidth of an NR carrier measured within a subframe (1 ms) period.
[0007] The A-MPR value of the SL-U for power level 5 terminals is required. Summary of the Invention

Examples of multiple access systems include Code Division Multiple Access (CDMA) systems, Frequency Division Multiple Access (FDMA) systems, Time Division Multiple Access (TDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, Single-Carrier Frequency Division Multiple Access (SC-FDMA) systems, and Multi-Carrier Frequency Division Multiple Access (MC-FDMA) systems. CDMA can be implemented using radio technologies such as Universal Terrestrial Radio Access (UTRA) or CDMA2000. TDMA can be implemented using radio technologies such as Global System for Mobile Communications (GSM), General Packet Radio Service (GPRS), or Enhanced Data Rate GSM Evolution (EDGE). OFDMA can be implemented using radio technologies such as IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, or Evolved UTRA (E-UTRA).

[0113] Although not limited thereto, the various descriptions, functions, processes, suggestions, methods and / or operation flowcharts disclosed herein can be applied to various fields that require wireless communication and / or connectivity between devices (e.g., 5G).
[0114] In the following description, this disclosure will be described in more detail with reference to the accompanying drawings. Unless otherwise stated, the same reference numerals in the following drawings and / or description may refer to the same and / or corresponding hardware blocks, software blocks and / or functional blocks.
[0115] Figure 1 An example of a communication system that applies the implementation of this disclosure is shown.
[0116] Figure 1 The 5G use cases shown are merely illustrative, and the technical features of this disclosure can be applied to... Figure 1 Other 5G use cases not shown.
[0117] The three main requirement categories for 5G include (1) Enhanced Mobile Broadband (eMBB), (2) Massive Machine-Type Communications (mMTC), and (3) Ultra-Reliable and Low-Latency Communications (URLLC).
[0118] Reference Figure 1The communication system 1 includes wireless devices 100a to 100f, a base station (BS) 200, and a network 300. Although Figure 1 An example of a 5G network as a network of communication system 1 is illustrated, but the implementation of this disclosure is not limited to 5G systems and can be applied to future communication systems other than 5G systems.
[0119] BS 200 and network 300 can be implemented as wireless devices, and a particular wireless device can operate as a BS / network node relative to other wireless devices.
[0120] Wireless devices 100a to 100f represent devices that perform communication using radio access technology (RAT) (e.g., 5G NR or LTE) and may be referred to as communication / radio / 5G devices. Wireless devices 100a to 100f may include, but are not limited to, robots 100a, vehicles 100b-1 and 100b-2, extended reality (XR) devices 100c, handheld devices 100d, home appliances 100e, Internet of Things (IoT) devices 100f, and artificial intelligence (AI) devices / servers 400. For example, vehicles may include vehicles with wireless communication capabilities, autonomous vehicles, and vehicles capable of performing communication between vehicles. Vehicles may include unmanned aerial vehicles (UAVs) (e.g., drones). XR devices may include augmented reality (AR) / virtual reality (VR) / mixed reality (MR) devices and may be implemented in the form of head-mounted displays (HMDs), head-up displays (HUDs) installed in vehicles, televisions, smartphones, computers, wearable devices, home appliances, digital signage, vehicles, robots, etc. Handheld devices may include smartphones, smart tablets, wearable devices (e.g., smartwatches or smart glasses), and computers (e.g., laptops). Home appliances may include TVs, refrigerators, and washing machines. IoT devices may include sensors and smart meters.
[0121] In this disclosure, wireless devices 100a to 100f may be referred to as user equipment (UE). UE may include, for example, cellular phones, smartphones, laptops, digital broadcasting terminals, personal digital assistants (PDAs), portable multimedia players (PMPs), navigation systems, tablet PCs, tablet PCs, ultrabooks, vehicles, vehicles with autonomous driving capabilities, connected cars, UAVs, AI modules, robots, AR devices, VR devices, MR devices, holographic devices, public safety devices, MTC devices, IoT devices, medical devices, FinTech devices (or financial devices), security devices, weather / environment devices, devices related to 5G services, or devices related to the Fourth Industrial Revolution.
[0122] Wireless devices 100a to 100f can connect to network 300 via BS 200. AI technology can be applied to wireless devices 100a to 100f, and wireless devices 100a to 100f can connect to AI server 400 via network 300. Network 300 can be configured using 3G, 4G (e.g., LTE), 5G (e.g., NR), and super 5G networks. Although wireless devices 100a to 100f can communicate with each other via BS 200 / network 300, wireless devices 100a to 100f can also perform direct communication (e.g., sidelink communication) without going through BS 200 / network 300. For example, vehicles 100b-1 and 100b-2 can perform direct communication (e.g., vehicle-to-vehicle (V2V) / vehicle-to-everything (V2X) communication). IoT devices (e.g., sensors) can perform direct communication with other IoT devices (e.g., sensors) or other wireless devices 100a to 100f.
[0123] Wireless communication / connections 150a, 150b, and 150c can be established between wireless devices 100a to 100f and / or between wireless devices 100a to 100f and BS 200 and / or between BS 200. In this document, wireless communication / connections can be established via various RATs (e.g., 5G NR) such as uplink / downlink communication 150a, sidelink communication (or device-to-device (D2D) communication) 150b, and inter-base station communication 150c (e.g., relay, integrated access and backhaul (IAB)). Wireless devices 100a to 100f and BS 200 / wireless devices 100a to 100f can send / receive radio signals to / from each other via wireless communication / connections 150a, 150b, and 150c. For example, wireless communication / connections 150a, 150b, and 150c can send / receive signals via various physical channels. Therefore, at least a portion of various configuration information configuration processes, various signal processing processes (e.g., channel coding / decoding, modulation / demodulation, and resource mapping / demapping), and resource allocation processes for transmitting / receiving radio signals can be performed based on various proposals of this disclosure.
[0124] NR supports multiple parameter sets (and / or multiple subcarrier spacings (SCS)) to support a variety of 5G services. For example, if the SCS is 15 kHz, wide-area coverage can be supported in traditional cellular bands, and if the SCS is 30 kHz / 60 kHz, dense urban areas, lower latency, and wider carrier bandwidth can be supported. If the SCS is 60 kHz or higher, bandwidths greater than 24.25 GHz can be supported to overcome phase noise.
[0125] NR bands can be defined as two types of frequency ranges: frequency range 1 (FR1) and frequency range 2 (FR2). The numerical values of the frequency ranges can vary. For example, the two types (FR1 and FR2) of frequency ranges can be shown in Table 1. For ease of explanation, in the frequency ranges used in NR systems, FR1 can refer to "below 6 GHz" and FR2 can refer to "above 6 GHz," and can also be referred to as millimeter wave (mmW).
[0126] [Table 1]
[0127] As described above, the frequency range of the NR system can be varied. For example, FR1 may include a frequency band from 410 MHz to 7125 MHz as shown in Table 2 below. That is, FR1 may include a frequency band of 6 GHz (or 5850 MHz, 5900 MHz, 5925 MHz, etc.) or higher. For example, the 6 GHz (or 5850 MHz, 5900 MHz, 5925 MHz, etc.) or higher frequency band included in FR1 may include unlicensed frequency bands. Unlicensed frequency bands can be used for various purposes (e.g., for vehicle communications (e.g., autonomous driving)).
[0128] [Table 2]

[0161] <6G System Overview>
[0162] 6G (wireless communication) systems aim to achieve goals such as (i) very high data rates per device, (ii) a very large number of connected devices, (iii) global connectivity, (iv) very low latency, (v) reduced energy consumption for battery-free IoT devices, (vi) ultra-reliable connectivity, and (vii) connected intelligence with machine learning capabilities. The concept of 6G systems can include four aspects: “intelligent connectivity,” “deep connectivity,” “holographic connectivity,” and “universal connectivity,” and 6G systems can meet the requirements shown in Table 3 below. In other words, Table 3 shows the requirements for 6G systems.
[0163] [Table 3]
[0164] 6G systems can have key elements such as enhanced mobile broadband (eMBB), ultra-reliable low-latency communication (URLLC), massive machine-type communication (mMTC), AI-integrated communication, tactile internet, high throughput, high network capacity, high energy efficiency, low backhaul and access network congestion, and enhanced data security.
[0165] Figure 4 This is a diagram illustrating an example of a communication architecture that can be provided in a 6G system.
[0166] 6G systems will offer 50 times more simultaneous wireless connectivity than 5G systems. In 6G communication, URLLC (a key feature of 5G) will become even more important due to its ability to provide end-to-end latency of less than 1 ms. Unlike the frequently used regional spectral efficiency, 6G systems can achieve significantly better volumetric spectral efficiency. 6G systems can offer advanced battery technologies for energy harvesting and very long battery life, meaning mobile devices may not require separate charging. Furthermore, new network characteristics may emerge in 6G.
[0167] - Satellite-integrated networks: To provide global mobile coverage, 6G will be integrated with satellites. Integrating terrestrial waves, satellites, and public networks into a single wireless communication system will likely be crucial for 6G.
[0168] - Connecting Intelligence: Unlike previous generations of wireless communication systems, 6G is revolutionary, and wireless evolution can be updated from "connecting things" to "connecting intelligence." AI can be applied to every step of the communication process (or every signal processing step described below).
[0169] - Seamless integration of wireless messaging and power transfer: 6G wireless networks can deliver power to charge the batteries of devices such as smartphones and sensors. Therefore, wireless messaging and power transfer (WIET) will be integrated.
[0170] - Ubiquitous super 3-dimensional connectivity: Access to networks and core network functions for drones and very low Earth orbit satellites will establish ubiquitous super 3-dimensional connectivity in 6G.
[0171] Among the new network features of 6G, several general requirements may be as follows.
[0172] - Small Cell Networks: The concept of small cell networks was introduced to improve throughput, energy efficiency, and spectral efficiency in cellular systems, thereby enhancing received signal quality. Therefore, small cell networks are a fundamental feature of 5G and beyond (5G) communication systems. Consequently, 6G communication systems will also adopt the characteristics of small cell networks.
[0173] - Ultra-dense heterogeneous networks: Ultra-dense heterogeneous networks will be another important feature of 6G communication systems. Multi-layered networks composed of heterogeneous networks can improve overall QoS and reduce costs.
[0174] - High-capacity backhaul: Backhaul connections are characterized by a high-capacity backhaul network to support high-capacity services. High-speed fiber optic and free-space optics (FSO) systems may be a possible solution to this problem.
[0175] - Radar technology integrated with mobile technology: High-precision positioning (or location-based services) via communication is one of the functions of 6G wireless communication systems. Therefore, radar systems will be integrated with 6G networks.
[0176] - Software and virtualization: Software and virtualization are two important features that form the basis of the design process in 5GB networks to ensure flexibility, reconfigurability and programmability.
[0177] <Core Implementation Technologies of 6G Systems>
[0178] AI
[0179] The most important and newly introduced technology in 6G systems is AI. 4G systems do not involve AI. 5G systems will support some or very limited AI. However, 6G systems will support AI for full automation. In 6G, advances in machine learning will create smarter networks for real-time communication. When AI is introduced into communication, it can simplify and improve real-time data transmission. AI can use numerous analyses to determine methods for performing complex tasks. In other words, AI can improve efficiency and reduce processing latency.
[0180] AI can be used to immediately execute time-consuming tasks such as switching, network selection, and resource scheduling. AI can even play a significant role in M2M, machine-to-human, and human-to-machine communication. Furthermore, AI can enable rapid communication in brain-computer interfaces (BCIs). AI-based communication systems can be supported by metamaterials, smart structures, smart networks, smart devices, intelligent cognitive radios, self-maintaining wireless networks, and machine learning.
[0181] Recently, attempts have been made to integrate AI with wireless communication systems at the application or network layers, but deep learning has been primarily focused on wireless resource management and allocation. However, this research is gradually expanding to the MAC and physical layers, specifically attempting to combine deep learning in the physical layer with wireless transmission. AI-based physical layer transmission refers to the application of AI-driven signal processing and communication mechanisms, rather than traditional communication frameworks based on fundamental signal processing and communication mechanisms. Examples include deep learning-based channel coding and decoding, deep learning-based signal estimation and detection, deep learning-based multiple-input multiple-output (MIMO) mechanisms, and AI-based resource scheduling and allocation.
[0182] Machine learning can be used for channel estimation and channel tracking, and for power allocation and interference cancellation in the physical layer of deep learning. Additionally, machine learning can be used for antenna selection, power control, and symbol detection in MIMO systems.
[0183] Machine learning refers to a series of operations used to train machines to perform tasks that are impossible or difficult for humans to perform. Machine learning requires data and a learning model. In machine learning, data learning methods can be broadly categorized into three types: supervised learning, unsupervised learning, and reinforcement learning.
[0184] Neural network learning aims to minimize output error. It involves repeatedly feeding training data into the neural network, calculating the error between the network's output and the target value based on the training data, backpropagating the error from the output layer back to the input layer to reduce it, and updating the weights of each node in the neural network.
[0185] Supervised learning can use training data labeled with correct answers, while unsupervised learning can use training data without labeled correct answers. That is, for example, in supervised learning for data classification, training data can be labeled with categories. The labeled training data can be input into a neural network, and the network's output (category) can be compared with the labels of the training data to calculate the error. The calculated error is backpropagated from the neural network backward (that is, from the output layer to the input layer), and the connection weights of each node in each layer of the neural network can be updated based on the backpropagation. The change in the updated connection weights of each node can be determined based on the learning rate. The computation of the neural network on the input data and the backpropagation of the error can be configured with a learning period (epoch). The learning data is adapted differently depending on the number of repetitions of the neural network's learning period. For example, a high learning rate can be used in the early stages of neural network learning to improve efficiency, allowing the neural network to quickly establish a certain level of performance, while a low learning rate can be used in the later stages of learning to improve accuracy.
[0186] Learning methods can vary depending on the characteristics of the data. For example, to accurately predict the data transmitted from the transmitter in a receiver of a communication system, supervised learning can be used instead of unsupervised learning or reinforcement learning.
[0187] The learning model corresponds to the human brain and can be viewed as the most basic linear model. However, the paradigm of machine learning that uses highly complex neural network structures (such as artificial neural networks) as learning models is called deep learning.
[0188] The core neural networks used as learning methods can broadly include deep neural networks (DNNs), convolutional deep neural networks (CNNs), recurrent Boltzmann machines (RNNs), and spiking neural networks (SNNs). Such learning models are applicable.
[0189] THz (Terahertz) communication
[0190] Data rates can be increased by increasing bandwidth. This can be achieved by using sub-THz communication with wide bandwidth and applying advanced massive MIMO technology. THz waves (also known as submillimeter radiation) typically refer to a frequency band between 0.1 THz and 10 THz, corresponding to wavelengths in the range of 0.03 mm to 3 mm. The 100 GHz to 300 GHz frequency band (sub-THz band) is considered the main part of the THz band used for cellular communication. When the sub-THz band is added to the millimeter-wave band, 6G cellular communication capacity is increased. The 300 GHz to 3 THz band in the defined THz band is in the far-infrared (IR) band. The 300 GHz to 3 THz band is part of the optical band, but it is on the boundary of the optical band and just behind the RF band. Therefore, the 300 GHz to 3 THz band has similarities to RF.
[0191] Figure 5 An example of the electromagnetic spectrum is shown.
[0192] The key characteristics of THz communication include (i) a wide range of available bandwidth supporting very high data rates, and (ii) high path loss occurring at high frequencies (making highly directional antennas indispensable). The narrow beamwidth generated in highly directional antennas reduces interference. The small wavelength of THz signals allows for the integration of a larger number of antenna elements with devices and base stations operating in this band. Therefore, advanced adaptive placement techniques capable of overcoming range limitations can be used.
[0193] Massive MIMO
[0194] One of the core technologies used to improve spectral efficiency is MIMO (Multi-channel Mixing). As MIMO technology improves, spectral efficiency also increases. Therefore, massive MIMO will be crucial in 6G systems. Since MIMO uses multiple paths, emphasis should be placed on multiplexing and beamforming techniques suitable for the THz band to enable data signal transmission through one or more paths.
[0195] Holographic beamforming
[0196] Beamforming is the signal processing procedure of adjusting an antenna array to transmit radio signals in a specific direction. It is a subset of smart antennas or advanced antenna systems. Beamforming technology offers numerous advantages such as high signal-to-noise ratio, interference prevention and suppression, and high network efficiency. Holographic beamforming (HBF) is a novel beamforming method that differs significantly from MIMO systems because it uses software-defined antennas. HBF will be a highly effective method for efficiently and flexibly transmitting and receiving signals in multi-antenna communication devices in 6G.
[0197] Optical wireless technology
[0198] Optical wireless communication (OWC) is a form of optical communication that uses visible light, infrared light (IR), or ultraviolet light (UV) to transmit signals. OWC operating in the visible light band (e.g., 390 nm to 750 nm) is often referred to as visible light communication (VLC). VLC can be implemented using light-emitting diodes (LEDs). VLC can be used in a variety of applications, including wireless local area networks, wireless personal communication networks, and vehicular networks.
[0199] VLC offers several advantages over RF-based technologies. First, VLC occupies a largely untapped / unlicensed spectrum and provides extensive bandwidth (THz levels). Second, VLC causes minimal interference to other electromagnetic devices; therefore, it can be used in electromagnetically sensitive applications such as aircraft and hospitals. Third, VLC offers advantages in communication security and privacy. The transmission medium of VLC-based networks (i.e., visible light) cannot penetrate walls and other opaque obstacles. Therefore, VLC's transmission range can be limited to indoor environments, protecting user privacy and sensitive information. Fourth, VLC can use any light source as a base station, eliminating the need for expensive base stations.
[0200] Free-space optical communication (FSO) is an optical communication technology that uses light propagating in free space (such as air), outer space, and vacuum to wirelessly transmit data for use in telecommunications or computer networks. FSO can be used as a terrestrial point-to-point OWC system. FSO can operate in the near-infrared frequency range (750 nm–1600 nm). Laser transmitters can be used in FSO implementations, and FSO can provide high data rates (e.g., 10 Gbit / s), thus offering a potential solution to backhaul bottlenecks.
[0201] In addition to RF-based communication for any possible device-to-access network, these OWC technologies are also planned for 6G communication. These networks will connect access networks to backhaul / fronthaul networks. OWC technology has been in use since 4G communication systems, but will be more widely used to meet the needs of 6G communication systems. OWC technologies such as optical fidelity, visible light communication, optical camera communication, and FSO communication based on optical bands are already well-known. Optical wireless communication can provide very high data rates, low latency, and secure communication.
[0202] LiDAR (Light Detection and Ranging) can also be used for ultra-high resolution 3D mapping in 6G communications based on optical bands. LiDAR is a remote sensing method that uses near-infrared, visible, and ultraviolet light to illuminate an object and the reflected light is detected by a light sensor to measure distance. LiDAR can be used for fully autonomous driving in automobiles.
[0203] FSO Backhaul Network
[0204] The transmitters and receivers of an FSO system exhibit characteristics similar to those of a fiber optic network. Therefore, data transmission in an FSO system is analogous to that in a fiber optic system. Consequently, FSO can be a good technology for providing backhaul connectivity in 6G systems alongside fiber optic networks. When using FSO, very long-distance communication is possible, even at distances of 10,000 km or more. FSO supports extensive backhaul connectivity for both long-range and short-range areas such as oceans, space, underwater, and isolated islands. FSO also supports cellular base station connectivity.
[0205] NTN: Non-Terrestrial Networks
[0206] 6G systems will integrate terrestrial and airborne networks to support vertically extended user communications. 3D BS will be provided via LEO satellites and UAVs. Adding new dimensions in terms of altitude and associated degrees of freedom makes 3D connectivity quite different from traditional 2D networks. NR considers non-terrestrial networks (NTNs) as one way to achieve this. NTNs are networks or network segments that utilize RF resources on satellites (or UAS platforms). For NTNs providing access to user equipment, there are two common scenarios: transparent payloads and regenerative payloads. The following are the basic elements of NTNs.
[0207] - Connect the NTN to one or more SAT gateways in the public data network.
[0208] - GEO satellites are fed by one or more SAT gateways deployed across satellite target coverage areas (e.g., regional or continental coverage areas). We assume that a UE in a cell is served by only one SAT gateway.
[0209] - Non-GEO satellites continuously served by one or more satellite gateways. The system ensures service and feeder link continuity between continuously serving satellite gateways for a duration sufficient to allow for mobility anchoring and handover.
[0210] - Feeder link or radio link between the satellite gateway and the satellite (or UAS platform).
[0211] - Service link or radio link between user equipment and satellite (or UAS platform).
[0212] - A satellite (or UAS platform) capable of providing transparent or regenerated (including airborne processing) payloads. The satellite (or UAS platform) generates beams, typically multiple beams for a given service area based on its field of view. The coverage area of the beams is usually elliptical. The field of view of the satellite (or UAS platform) depends on the airborne antenna pattern and the minimum angle of attack.
[0213] - Transparent payload: RF filtering, frequency conversion, and amplification. Therefore, the waveform signal repeated by the payload remains unchanged.
[0214] - Regenerated payload: RF filtering, frequency conversion and amplification, demodulation / decryption, switching and / or routing, and encoding / modulation. This is essentially the same as carrying all or part of the base station functions (e.g., gNB) on a satellite (or UAS platform).
[0215] - Optionally, for satellite deployments, inter-satellite links (ISLs) are used. This requires a regenerative payload on the satellite. ISLs can operate in RF frequencies or optical bands.
[0216] - User equipment is served by satellites (or UAS platforms) within the target coverage area.
[0217] Typically, GEO satellites and UAS are used to provide services to a continent, region, or local area.
[0218] Typically, constellations in LEO and MEO are used to provide service in both the Northern and Southern Hemispheres. In some cases, constellations can also provide global coverage, including polar regions. The latter requires appropriate orbital inclination, sufficient generated beams, and links between satellites.
[0219] Quantum communication
[0220] Quantum communication is a next-generation communication technology that overcomes the limitations of traditional communication (such as security and ultrafast computing) by applying the properties of quantum mechanics to the field of communication. Quantum communication provides a means to generate, send, process, and store information that cannot be expressed in the form of 0s and 1s using binary bits as in conventional communication technologies, or that is difficult to express. In conventional communication technologies, wavelength or amplitude is used to transmit information between the sender and receiver, but in quantum communication, photons, as the smallest unit of light, are used to transmit information between the sender and receiver. Specifically, in the case of quantum communication, quantum uncertainty and quantum irreversibility can be used to manipulate the polarization or phase difference of photons (light), thus quantum communication possesses the characteristic of being able to communicate with perfect security. Quantum communication can also achieve ultrafast communication under certain conditions using quantum entanglement.
[0221] Cellular communication
[0222] The tight integration of multiple frequencies and heterogeneous communication technologies is crucial for 6G systems. As a result, users will be able to seamlessly move from one network to another without having to create any manual configurations on their devices. The best network will be automatically selected from the available communication technologies. This will break down the limitations of the cell concept in wireless communication. Currently, moving from one cell to another in dense networks causes excessive handovers, resulting in handover failures, handover delays, data loss, and the ping-pong effect. 6G cell-free communication will overcome all of these and provide better QoS.
[0223] Cellular-free communication is defined as "a system in which multiple geographically distributed antennas (APs) collaboratively serve a small number of terminals using the same time / frequency resources, with the aid of a fronthaul network and a CPU." A single terminal is served by a collection of multiple APs (called an AP cluster). There are several ways to form AP clusters, one of which is a terminal-centric clustering method that utilizes APs that significantly improve the terminal's reception performance, and dynamically updates the configuration as the terminal moves. This device-centric AP clustering technique ensures that the device is always at the center of the AP cluster and is therefore unaffected by inter-cluster interference that may occur when the device is located at the cluster's boundary. This cellless communication is achieved through multi-connectivity and multi-layer hybrid technologies, as well as different heterogeneous radios within the device.
[0224] Integration of Wireless Information and Power Transfer (WIET)
[0225] WIET uses the same fields and waves as wireless communication systems. Specifically, sensors and smartphones will use wireless power transmission to charge during communication. WIET is a promising technology for extending the lifespan of wireless battery charging systems. Therefore, devices without batteries will be supported in 6G communications.
[0226] Integration of wireless communication and sensing
[0227] Autonomous wireless networks are capable of continuously detecting dynamically changing environmental conditions and exchanging information between different nodes. In 6G, sensing will be tightly integrated with communication to support autonomous systems.
[0228] Integrated access and backhaul networks
[0229] In 6G, the density of access networks will be enormous. Each access network will be connected via fiber optic cables and backhaul connections (such as FSO networks). To handle the very large number of access networks, there will be tight integration between the access networks and the backhaul networks.
[0230] Big data analytics
[0231] Big data analytics is a complex process used to analyze various large datasets or big data. This process uncovers information such as hidden data, unknown correlations, and customer actions to ensure comprehensive data management. Big data is collected from various sources such as videos, social networks, images, and sensors. This technology is widely used in 6G systems to process massive amounts of data.
[0232] Reconfigurable Intelligent Metasurface
[0233] Numerous studies have explored the radio environment as a variable to be optimized along with the transmitter and receiver. The radio environment created by this approach is termed a Smart Radio Environment (SRE) or Intelligent Radio Environment (IRE) to highlight its fundamental difference from past design and optimization criteria. Various terms have been proposed for reconfigurable smart antennas (or smart reconfigurable antenna technologies) used to enable SRE, including reconfigurable metasurfaces, large smart surfaces (SLIS), large smart surfaces (LIS), reconfigurable smart surfaces (RIS), and smart reflective surfaces (IRS).
[0234] In the case of THz band signals, numerous shadowed regions caused by obstacles exist due to the signal's rigidity. RIS (Radio Reflector Array) technology is important for extending communication range by enhancing communication stability and providing additional value-added services through the installation of RIS near these shadowed regions. RIS are artificial surfaces made of electromagnetic materials that can alter the propagation of incoming and outgoing radio waves. While RIS can be considered an extension of massive MIMO, it has a different array structure and operating mechanism. RIS offers the advantage of low power consumption because it operates as a reconfigurable reflector with passive components; that is, it passively reflects signals without using an active RF chain. Furthermore, each of the passive reflectors in the RIS must independently adjust the phase shift of the incoming signal, which can be advantageous for wireless communication channels. By appropriately adjusting the phase shift using the RIS controller, the reflected signal can be collected at the target receiver to improve the received signal power.
[0235] In addition to reflecting radio signals, there are also radio signals that can be tuned for both transmission and refraction characteristics, and these radio signals are often used in outdoor-to-indoor (O2I) applications. Recently, STAR-RIS (simultaneous transmission and reflection radio signals) that provide transmission while reflecting signals have also been actively researched.
[0236] metaverse
[0237] The metaverse is a combination of the words "meta," "transcendent," and "universe," which refer to space. Generally, the term is used to describe a three-dimensional virtual space where social and economic activities are identical to those in the real world.
[0238] Extended Reality (XR) (a key technology for realizing the metaverse) is a fusion of virtual and real, extending real-world experiences and providing unique immersive experiences. The high bandwidth and low latency of 6G networks will enable users to experience more immersive virtual reality (VR) and augmented reality (AR) experiences.
[0239] Autonomous driving (autonomous driving)
[0240] For fully autonomous driving, vehicles need to communicate with each other to warn of dangerous situations, or with infrastructure such as parking lots and traffic lights to check information such as parking location and signal change times. Vehicle-to-everything (V2X) (a key element in building autonomous driving infrastructure) is a technology that enables vehicles to communicate with various elements on the road and share information (such as vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I)) to drive autonomously.
[0241] To maximize the performance and ensure high safety of autonomous driving, high-speed transmission and low-latency technologies are essential. Furthermore, in the future, autonomous driving will go beyond simply delivering warnings or guidance messages to the driver to proactively intervene in vehicle operation and directly control the vehicle in dangerous situations. The amount of information that needs to be sent and received will be enormous; therefore, 6G is expected to maximize autonomous driving with its faster transmission speeds and lower latency compared to 5G.
[0242] Unmanned aerial vehicles (UAVs)
[0243] Unmanned aerial vehicles (UAVs), or drones, will be a crucial element in 6G wireless communication. In most cases, UAV technology will be used to provide high-speed data wireless connectivity. Base station entities are installed within UAVs to provide cellular connectivity. UAVs possess specific characteristics not found in fixed base station infrastructure, such as ease of deployment, strong line-of-sight links, and degrees of freedom in controlled mobility. During emergencies such as natural disasters, the deployment of terrestrial telecommunications infrastructure is economically infeasible and sometimes unable to provide service in volatile environments. UAVs can easily handle such situations. UAVs will be a new paradigm in the field of wireless communication. This technology contributes to the three fundamental requirements of wireless networks, such as eMBB, URLLC, and mMTC. UAVs can also serve numerous 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 considered one of the most important technologies for 6G communications.
[0244] Blockchain
[0245] Blockchain will be a crucial technology for managing massive amounts of data in future communication systems. Blockchain is a form of distributed ledger technology, and a distributed ledger is a database distributed across numerous nodes or computing devices. Each node replicates and stores an identical copy of the ledger. Blockchain is managed through a peer-to-peer (P2P) network. This can exist without being managed by a centralized institution or server. Blockchain data is collected together and organized into blocks. Blocks are linked together and protected using encryption. Blockchain fully complements large-scale IoT through improved interoperability, security, privacy, stability, and scalability. Therefore, blockchain technology offers multiple capabilities such as interoperability between devices, high-volume data traceability, autonomous interaction between different IoT systems, and the massive connectivity stability of 6G communication systems.
[0246] Figure 6 It is a wireless communication system.
[0247] For reference Figure 6 As can be seen, a wireless communication system includes at least one base station (BS). The BS is divided into gNodeB (or gNB) 20a and eNodeB (or eNB) 20b. gNB (20a) supports fifth-generation mobile communication. eNB (20b) supports fourth-generation mobile communication, namely, Long Term Evolution (LTE).
[0248] Each base station 20a and 20b provides communication services for a specific geographical area (usually called a cell) 20-1, 20-2, and 20-3. A cell can be further divided into multiple areas (called sectors).
[0249] A UE typically belongs to a cell, and the cell to which the UE belongs is called the serving cell. The base station that provides communication services to the serving cell is called the serving BS. Since wireless communication systems are cellular systems, there are other cells adjacent to the serving cell. These other cells adjacent to the serving cell are called neighboring cells. The base stations that provide communication services to neighboring cells are called neighboring base stations (neighboring BSs). The serving cell and neighboring cells are determined relatively based on the UE.
[0250] In the following text, downlink refers to communication from base station 20 to UE 10, and uplink refers to communication from UE 10 to base station 20. In the downlink, the transmitter may be part of base station 20, and the receiver may be part of UE 10. In the uplink, the transmitter may be part of UE 10, and the receiver may be part of base station 20.
[0251] Furthermore, wireless communication systems can be broadly classified into FDD (Frequency Division Duplex) and TDD (Time Division Duplex) methods. According to the FDD method, uplink and downlink transmissions occur at different times, occupying different frequency bands. According to the TDD method, uplink and downlink transmissions occupy the same frequency band but occur at different times. The channel responses of the TDD method are essentially inverses of each other. This means that in a given frequency region, the downlink channel response and the uplink channel response are almost identical. Therefore, in TDD-based wireless communication systems, there is an advantage in obtaining the downlink channel response from the uplink channel response. In the TDD method, uplink and downlink transmissions are time-divided across the entire frequency band, so downlink transmissions performed by the base station and uplink transmissions performed by the UE cannot be performed simultaneously. In TDD systems where uplink and downlink transmissions are based on subframe separation, uplink and downlink transmissions are performed in different subframes.
[0252] <Operating Frequency Band>
[0253] The operating frequency bands in NR are as follows.
[0254] Table 4 shows an example of the operating frequency band on FR1. The operating frequency band shown in Table 4 is a reconstructed operating frequency band converted from the operating frequency band of LTE / LTE-A. This operating frequency band can be referred to as the FR1 operating frequency band.
[0255] [Table 4]
[0256] Table 5 shows an example of the operating frequency bands on FR2. The following shows the operating frequency bands defined at high frequencies. This operating frequency band is called the FR2 operating frequency band.
[0257] [Table 5]
[0258] Figure 7 The structure of a radio frame used in NR is illustrated.
[0259] In NR, uplink and downlink transmissions consist of frames. A radio frame is 10 ms long and is defined as two 5 ms half-frames (HF). A half-frame is defined as five 1 ms subframes (SF). Subframes are divided into one or more time slots, and the number of time slots in a subframe depends on the SCS (subcarrier spacing). Each time slot includes 12 or 14 OFDM(A) symbols, depending on the CP (cyclic prefix). When using CP, each time slot includes 14 symbols. When using extended CP, each time slot includes 12 symbols. Here, symbols can include OFDM symbols (or CP-OFDM symbols) and SC-FDMA symbols (or DFT-s-OFDM symbols).
[0260] Figure 8 An example of subframe types in NR is shown.
[0261] Figure 8 The TTI (Transmission Time Interval) shown can be referred to as a subframe or time slot for NR (or New RAT). Figure 8 Subframes (or time slots) can be used in NR (or New RAT) TDD systems to minimize data transmission latency. For example... Figure 8 As shown, a subframe (or time slot) comprises 14 symbols, as in the current subframe. The first few symbols of a subframe (or time slot) can be used for the DL control channel, and the last few symbols can be used for the UL control channel. The remaining symbols can be used for either DL data transmission or UL data transmission. Based on this subframe (or time slot) structure, downlink and uplink transmissions can be performed sequentially within a single subframe (or time slot). Therefore, downlink data can be received within a subframe (or time slot), and uplink acknowledgments (ACK / NACK) can be sent within the same subframe (or time slot).
[0262] This structure of a subframe (or time slot) can be called a self-contained subframe (or time slot).
[0263] Specifically, the first N symbols in a timeslot can be used to transmit the DL control channel (hereinafter, the DL control area), and the last M symbols in a timeslot can be used to transmit the UL control channel (hereinafter, the UL control area). N and M are each integers greater than or equal to 0. The resource area between the DL control area and the UL control area (hereinafter referred to as the data area) can be used for either DL data transmission or UL data transmission. For example, a PDCCH can be transmitted in the DL control area, and a PDSCH can be transmitted in the DL data area. A PUCCH can be transmitted in the UL control area, and a PUSCH can be transmitted in the UL data area.
[0264] When using such a subframe (or time slot) structure, the time spent retransmitting data with received errors is reduced, thus minimizing the final data transmission delay. In this self-contained subframe (or time slot) structure, time gaps may be required during transitions from transmit mode to receive mode or from receive mode to transmit mode. Therefore, when switching from DL to UL in the subframe structure, some OFDM symbols can be set to guard periods (GP).
[0265] Support for various parameter sets
[0266] Parameter sets can be defined by the length of the cyclic prefix (CP) and the subcarrier spacing. A cell can provide multiple parameter sets to the UE. When the index of the parameter set is represented by μ, the subcarrier spacing and the corresponding CP length can be expressed as shown in the table below.
[0267] [Table 6]
[0268] Under normal CP conditions, when the parameter set index is represented by μ, the following table shows the number of OLDM symbols per slot. Number of time slots per frame and the number of time slots per subframe .
[0269] [Table 7]
[0270] In the case of extended CP, when the index of the parameter set is represented by μ, the number of OLDM symbols per slot is expressed in the table below. Number of time slots per frame and the number of time slots per subframe .
[0271] [Table 8]
[0272] Maximum Output Power
[0273] Unless otherwise specified, the UE power class (PC) in Table 9 defines the maximum output power across all transmission bandwidths within the channel bandwidth of the NR carrier. The measurement period can be at least one subframe (1 ms).
[0274] [Table 9]
[0275] The UE supports a power level different from the basic UE power level of the frequency band, and the supported power level activates a higher maximum output power than the basic power level as follows.
[0276] - If the UE capability maxUplinkDutyCycle-PC2-FR1 field is not present and the proportion of uplink symbols transmitted during a specific evaluation period is greater than 50% (the exact evaluation period is greater than one radio frame); or
[0277] - If the UE capability maxUplinkDutyCycle-PC2-FR1 field does not exist, and the proportion of uplink symbols transmitted during a specific evaluation period is greater than the defined maxUplinkDutyCycle-PC2-FR1 (the exact evaluation period is one or more radio frames); or
[0278] - If a defined IE P-Max is provided and set to a maximum output power lower than the default power level.
[0279] - All requirements for the basic power level must be applied to the supported power levels, and the transmit power must be set.
[0280] - Otherwise, the defined IE P-Max is not provided or is set to a value higher than the maximum output power of the default power level, and the percentage of uplink symbols transmitted during a specific evaluation period is less than or equal to maxUplinkDutyCycle-PC2-FR1. Or
[0281] - If the defined IE P-Max is not provided or is set to a value higher than the maximum output power of the default power level, and the percentage of uplink symbols transmitted in a specific evaluation period is equal to 50%, or if maxUplinkDutyCycle-PC2-FR1 does not exist. (The exact evaluation period is one or more radio frames): - All requirements for the supported power levels must be applied, and the transmit power must be set.
[0282] <Maximum Power Reduction (MPR) and Permissible Additional MPR (A-MPR)>
[0283] Figure 9a and Figure 9b An example of a method for limiting the transmission power of a UE is shown.
[0284] Reference Figure 9a UE 100 can perform transmissions with limited transmission power. For example, UE 100 can perform uplink transmissions to the base station by reducing transmission power.
[0285] When the peak-to-average power ratio (PAPR) of the signal transmitted from UE 100 increases, UE 100 applies a maximum output power reduction (MPR) value to the transmitted power in order to limit the transmission power. By doing so, the linearity of the power amplifier PA inside the transceiver of UE 100 is reduced.
[0286] Reference Figure 9b The base station (BS) can request UE 100 to apply A-MPR by sending a network signal (NS) to UE 100. To avoid affecting adjacent frequency bands, A-MPR-related operations can be performed. Unlike the MPR mentioned above, A-MPR-related operations involve the base station additionally performing power reduction by sending an NS to UE 100 operating in a specific frequency band. In other words, when a UE receiving an NS receives an MPR signal, it can additionally apply A-MPR to determine the transmission power.
[0287] This specification relates to the transmission power of terminals used for sidelink communication in unlicensed frequency bands.
[0288] This specification may specify additional maximum transmit power reduction (MPR) performance requirements for S-SSB transmissions to meet spectrum masking specifications (ACLR, SEM, SE, in-band transmit), EVM specifications, and country-specific requirements for transmit power when the terminal power class is power class 5 (20 dBm).
[0289] In 3GPP, as defined in Table 10, the n46, n96, and n102 frequency bands can be unlicensed frequency bands.
[0290] [Table 10]
[0291] For SL-U communication in unlicensed frequency bands, 12 kHz and / or 30 kHz can be applied.
[0292] Describe the maximum output power (MOP).
[0293] The SL-U terminal can notify the NW of its power level information per frequency band or per frequency band combination (in the case of CA and DC) and transmit it at the corresponding maximum output power. The power level of the SL-U terminal can be power level 5 (20dBm).
[0294] Typically, if the corresponding MOP is greater than 23 dBm, the terminal can change the MOP to be equal to or less than 23 dBm in order to meet the Specific Absorption Rate (SAR) specification in FR1. This is a specification that the terminal's transmission power should not cause harm to human health or affect medical devices.
[0295] The power level 5 SL-U terminal may not need to perform any additional MOP reductions to meet SAR specifications.
[0296] An example of a standard scenario that applies MOP is as follows: - SL-U UE MOP in a single carrier of the FR1 unlicensed frequency bands (n46, n96, n102) In addition to the spectrum masking standard and the EVM standard, the terminal (UE) should meet the country-specific requirements for each frequency band, which are specified as additional maximum output power reduction (A-MPR).
[0297] If the information corresponding to the specified frequency band is notified to the UE as NS_value (network signal value) in NW (network) or as a pre-configured radio parameter, then the terminal should meet the corresponding A-MPR specification.
[0298] The UE can obtain the NS_value by receiving information from the NW.
[0299] Alternatively, the UE can obtain the NS_value from pre-configured radio parameters.
[0300] If an NS_value exists, the UE should use the function max(MPR, A-MPR) to set the actual configured transmit power. The A-MPR can be determined based on the NS_value (e.g., NS_31).
[0301] The UE can determine the maximum output power based on the actual configured transmit power.
[0302] In other words, the UE can determine the maximum output power based on the A-MPR. The UE can then transmit signals based on the maximum output power.
[0303] Unlicensed frequency bands may include NR bands n46, n96, and n102.
[0304] When the unlicensed frequency bands in Table 10 are used for side links, the duplex mode can be half-duplex (HD) instead of time-division duplex (TDD).
[0305] Table 11 shows the NR SL-U operating frequency band in FR1.
[0306] [Table 11]
[0307] The NS_value in the unlicensed frequency band can be found in Tables 12 and 13.
[0308] Table 12 shows the mapping of network signaling labels.
[0309] [Table 12]
[0310] Table 13 shows the mapping of extended network signaling labels.
[0311] [Table 13]
[0312] In the current SPEC, the NS_value and channel bandwidth in the unlicensed frequency band can be specified as shown in Table 14.
[0313] [Table 14]
[0314] The NR-ARFCN (NR Absolute Radio Frequency Channel Number) for unlicensed frequency bands is shown in Tables 15, 16, and 17. NR-ARFCN is used to define the RF reference frequency.
[0315] Table 15 shows the allowed N values for operation in frequency band n46. REF (NR-ARFCN).
[0316] [Table 15]
[0317] Table 16 shows the allowed N values for operation in frequency band 96. REF (NR-ARFCN).
[0318] [Table 16]
[0319] Table 17 shows the allowed N values for operations in frequency band 102. REF (NR-ARFCN)
[0320] [Table 17]
[0321] The RF reference frequency can be specified on the global frequency grid by the NR Absolute Radio Channel Number (NR-ARFCN) in the range (0…2016666). The NR-ARFCN is the RF reference frequency in MHz. The relationship between them is given by the following equation, where, and It can be given in Table 18, and It could be NR-ARFCN:
[0322] Table 18 shows the NR-ARFCN parameters for the global frequency grid.
[0323] [Table 18]
[0324] When the NS is notified by signaling and when the transmission overlaps with any part of a specified frequency range, the UE operation may meet the following additional requirements for the maximum average transmission power density specified in Table 19. In cases where the transmission overlaps with multiple frequency ranges, a minimum power density requirement may be applied. Table 19 shows the additional requirements for transmit power density.
[0325] [Table 19]

[0338] The requirements for the network signaling value "NS_30" will be described below.
[0339] When “NS_30” is indicated in the cell, the power transmitted by any UE on channels assigned within the 5150 MHz-5350 MHz, 5470 MHz-5725 MHz, and 5725 MHz-5850 MHz ranges should not exceed the levels specified in Tables 24, 25, and 26, respectively. These requirements also apply to the levels specified in Table 6.5.3.1-1 of TS 38.101-1 V17.10.0, which are less than the edge of the channel bandwidth. The frequency range.

[0356] The following description pertains to the requirements for network signaling values “NS_53”, “NS_54”, “NS_60”, “NS_66”, or “NS_67”.
[0357] When “NS_53,” “NS_54,” “NS_60,” “NS_66,” or “NS_67” is indicated in the cell, the power transmitted by any UE should not exceed the levels specified in Table 31. These requirements also apply to values less than those in Table 6.5.3.1-1 of TS38.101-1 V17.10.0 from the edge of the channel bandwidth. The frequency range.
[0358] Table 31 shows the additional requirements based on NS_53, NS_54, NS_60, NS_66, or NS_67.
[0359] [Table 31]
[0360] The requirements for the network signaling value "NS_58" will be described below.
[0361] When “NS_58” is indicated in the cell, the power transmitted by any UE on the assigned channel within the 5945 MHz-6425 MHz range should not exceed the levels specified in Table 32. These requirements also apply to the levels specified in Table 6.5.3.1-1 of TS38.101-1 V17.10.0, which are less than the channel bandwidth limits. The frequency range.
[0362] Table 32 shows the additional requirements based on NS_58.
[0363] [Table 32]
[0364] The requirements for the network signaling value "NS_61" will be described below.
[0365] When “NS_61” is indicated in the cell, the power transmitted by any UE should not exceed the levels specified in Table 33. These requirements also apply to the levels specified in Table 6.5.3.1-1 of TS 38.101-1 V17.10.0, which are less than the edge of the channel bandwidth. The frequency range.

[0367] [Table 33]
[0368] The requirements for network signaling values “NS_63” or “NS_69” will be described below.
[0369] When “NS_63” or “NS_69” is indicated in the cell, the power transmitted by any UE on the assigned channel within the 5945 MHz-6425 MHz range should not exceed the levels specified in Table 34. These requirements also apply to the levels specified in Table 6.5.3.1-1 of TS 38.101-1 V17.10.0, which are less than the channel bandwidth at the edge. The frequency range.
[0370] Table 34 shows the additional requirements based on NS_63 or NS_69.
[0371] [Table 34]
[0372] An ACLR can be specified for a first adjacent channel (ACLR1) and a second adjacent channel (ACLR2), wherein the center frequency of the first adjacent channel is derived from the center frequency of the assigned channel. The center frequency of the second adjacent channel is from the center of the assigned channel. The assigned channel power and ACLR1 / ACLR2 can be measured using a rectangular filter with a measurement bandwidth of CBW.
[0373] Instead of the general ACLR requirement, if the measured adjacent channel power is greater than -47 dBm, the ACLR should be higher than the value specified in Table 35.
[0374] Table 35 shows the ACLR requirements for shared spectrum channel access.
[0375] [Table 35]
[0376] The requirements for the network signaling value "NS_64" will be described below.
[0377] When “NS_64” is indicated in the cell, the power transmitted by any UE on the assigned channel within the 5945 MHz-6425 MHz range should not exceed the levels specified in Table 36. These requirements also apply to the levels specified in Table 6.5.3.1-1 of TS38.101-1 V17.10.0, which are less than the edge of the channel bandwidth. The frequency range.
[0378] Table 36 shows the additional requirements based on NS_64.
[0379] [Table 36]
[0380] I. First Publicly Released Content
[0381] n46 can be a frequency band based on NS_31.
[0382] n96 can be based on the NS_53, NS_60, or NS_61 frequency bands.
[0383] n102 can be based on the NS_58 frequency band.
[0384] Power class 5 SL-U terminals can meet the spectrum masking standards (ACLR, SEM, SE, in-band transmission), EVM standards, and the aforementioned requirements when transmitting signals. Therefore, the maximum transmit power can be reduced by "X" dB from 20 dBm. The corresponding maximum permissible "X" value should be specified as A-MPR (Maximum Transmit Power Reduction).
[0385] The MPR for SL-U UE can vary depending on the actual number of resource blocks (RBs) transmitted, RB locations, modulation order, and wideband operation transmission method.
[0386] SL communication can be based on the CP-OFDM method.
[0387] ACLR can be the adjacent channel leakage ratio. SEM can be the spectrum emission mask. SE can be spurious emission. In-band emission can be general in-band emission, carrier leakage, or I / Q pattern. EVM can be the error vector magnitude.
[0388] An example of a standard scenario in which A-MPR is applied is SL-U UE MPR in a single carrier of the FR1 unlicensed bands (n46, n96, n102).
[0389] For example, S-SSBs can be transmitted in a single RB set (20 MHz).
[0390] For example, S-SSBs can be sent in multiple RB sets (contiguous RB sets and non-contiguous RB sets).
[0391] For the method used to send S-SSB, the current conventions for RAN1 are as shown in Table 37.
[0392] [Table 37]
[0393] For the SL-U power level 5 S-SSB MPR, the assumptions in Table 38 can be considered.
[0394] [Table 38]
[0395] Figure 10 The S-SSB structure for the SL-U PC5 UE is shown.
[0396] Additionally, as shown in Table 39, the following test scenarios can be considered.
[0397] Table 39 shows the SL-U S-SSB MPR test scenario.
[0398] [Table 39]
[0399] Here, for the S-SSB {11 RBs}xN repeated RB position indices, "0" can mean that the starting RB index of {11 RBs} is 0. Furthermore, bitmap "1" can mean sending the corresponding RB set, and "0" can mean not sending the corresponding RB set for wideband operation.
[0400] Table 40 shows all possible bitmaps for subband configurations used for wideband operation. Wideband operation can be aggregated with multiple 20 MHz-based subbands. For SL-US-SSB MPR simulations, both continuous RB set bitmaps and non-contiguous RB set bitmaps are considered.
[0401] Table 40 shows a bitmap of all possible RB sets for subband configurations.
[0402] [Table 40]

[0406] Figure 11 The NS_31-S-SSB A-MPR simulation results for SL-U power level 5 are shown.
[0407] Figure 12 The S-SSB A-MPR simulation results for Tx power backoff with channel bandwidths of 20 MHz, 40 MHz, and 60 MHz for 1Tx SL-U power class 5, according to this disclosure, are shown.

[0409] Figure 14 The S-SSB A-MPR simulation results for Tx power backoff with a channel bandwidth of 100 MHz for 1Tx SL-U power level 5, according to this disclosure, are shown.
[0410] For NS_31, full RB allocation and partial RB allocation for sub-band operations can be reused.
[0411] - Fully allocated A-MPR may be applicable when all RBs in the 20 MHz channel or all RBs in all subbands used for wideband operation are fully allocated and all subbands are transmitted.
[0412] Partial Allocation A-MPR may be applied when one or more RBs in one or more subbands are not allocated, or when not all transmit subbands used for broadband operation are transmitted.
[0413] Alternatively, the following RB set configurations (subband configurations) in Table 41 can be considered.
[0414] Table 41 shows the external / internal subband configuration for SL-U wideband operation. The RB allocation configuration shown in Table 41 can be applied to tables recommending MPR values in this specification (e.g., Tables 83, 88, 94, 99, and 104).
[0415] [Table 41]
[0416] Table 41 shows whether each of the sub-bands was transmitted via bitmap expressions.
[0417] Each of the sub-bands can be a set of RBs and can be 20 MHz.
[0418] The bandwidth for all sub-bands can be the bandwidth of the broadband operating channel.
[0419] RB allocation can be configured with an external RB set or an internal RB set.
[0420] A bitmap expression can indicate whether each element in a sub-band has been transmitted. As a bitmap expression, each element in a sub-band can be either "1" or "0".
[0421] "1" can indicate that a sub-band has been transmitted.
[0422] "0" can indicate a sub-band that has not been transmitted.
[0423] For example, based on i) the subbands are continuous and ii) the wideband operating channel bandwidth is 40 MHz, the “11, 10, 01” as a bitmap expression is an external RB set configuration.
[0424] For example, based on i) the subbands are continuous and ii) the wideband operating channel bandwidth is 60 MHz, “111, 110, 011, 100, 001” as a bitmap expression is an external RB set configuration.
[0425] For example, based on i) the subband is continuous and ii) the wideband operating channel bandwidth is 80 MHz, “1111, 1110, 0111, 1100, 0011, 1000, 0001” in the bitmap expression is an external RB set configuration.
[0426] For example, based on i) the subband is continuous and ii) the wideband operating channel bandwidth is 100 MHz, “11111, 11110, 01111, 11100, 00111, 11000, 00011, 10000, 00001” in the bitmap expression is an external RB set configuration.
[0427] For example, based on i) the subbands are continuous and ii) the wideband operating channel bandwidth is 60 MHz, "010" in the bitmap expression is the internal RB set configuration.
[0428] For example, based on i) the subbands are continuous and ii) the wideband operating channel bandwidth is 80 MHz, “0110, 0100, 0010” in the bitmap expression is an internal RB set configuration.
[0429] For example, based on i) the subbands are continuous and ii) the wideband operating channel bandwidth is 100 MHz, “01110, 01100, 00110, 01000, 00010, 00100” in the bitmap expression is an internal RB set configuration.
[0430] For example, based on i) the subband is discontinuous and ii) the wideband operating channel bandwidth is 60 MHz, "101" in the bitmap expression is the configuration of the external RB set.
[0431] For example, based on i) the subband is discontinuous and ii) the wideband operating channel bandwidth is 80 MHz, “1101, 1011, 1010, 0101, 1001” in the bitmap expression is an external RB set configuration.
[0432] For example, based on i) the subband is discontinuous and ii) the wideband operating channel bandwidth is 100 MHz, the “11011, 11010, 01011, 11001, 10011, 10101, 10110, 01101, 10100, 00101, 10010, 01001, 11101, 10111, 10001” in the bitmap expression is an external RB set configuration.
[0433] For example, based on i) the subband is discontinuous and ii) the wideband operating channel bandwidth is 100 MHz, "01010" in the bitmap expression is an internal RB set configuration.
[0434] Table 42 shows the maximum values of the simulation results considering a combination of full / partial RB allocation and external / internal subband configuration.

[0450] The A-MPR values in Tables 43, 44 and / or 45 can correspond to the case "A=0".

[0459] - Fully allocated A-MPR may be applicable when all RBs in the 20 MHz channel or all RBs in all subbands used for wideband operation are fully allocated and all subbands are transmitted.

[0702] The definition of intra-carrier SEM in the gap between transmission channels can be found in Table 78.
[0703] Table 78 shows the in-carrier SEM for SL-U broadband operation.
[0704] [Table 78]
[0705] Here, the relative power transmitted by any UE should not exceed the most stringent level given by the spectrum transmit mask (carrier SEM) for operation of shared spectrum channel access with full channel bandwidth and the spectrum transmit mask (intra-carrier SEM) for non-transmit channels with channel bandwidth in the case of non-transmit channels at the edge of the assigned channel bandwidth.
[0706] II. Second Public Content
[0707] n46 can be a frequency band based on NS_31.
[0708] n96 can be based on the NS_53, NS_60, or NS_61 frequency bands.
[0709] n102 can be based on the NS_58 frequency band.
[0710] Power class 5 SL-U terminals can meet the spectrum masking standards (ACLR, SEM, SE, in-band transmission), EVM standards, and the aforementioned requirements when transmitting signals. Therefore, the maximum transmit power can be reduced by "X" dB from 20 dBm. The corresponding maximum permissible "X" value should be specified as A-MPR (Maximum Transmit Power Reduction).
[0711] The MPR for SL-U UE can vary depending on the actual number of resource blocks (RBs) transmitted, RB locations, modulation order, and wideband operation transmission method.
[0712] SL communication can be based on the CP-OFDM method.
[0713] ACLR can be the adjacent channel leakage ratio. SEM can be the spectrum emission mask. SE can be spurious emission. In-band emission can be general in-band emission, carrier leakage, or I / Q pattern. EVM can be the error vector magnitude.
[0714] An example of a standard scenario in which A-MPR is applied is SL-U UE MPR in a single carrier of the FR1 unlicensed bands (n46, n96, n102).
[0715] For example, S-SSBs can be transmitted in a single RB set (20 MHz).
[0716] For example, S-SSBs can be sent in multiple RB sets (contiguous RB sets and non-contiguous RB sets).
[0717] For the method used to send S-SSB, the current conventions for RAN1 are as shown in Table 79.
[0718] [Table 79]
[0719] For SL-U power class 5 S-SSB MPR, Table 38 (including) can be considered. Figure 10 The assumption.
[0720] In addition, the following test scenarios can be considered as shown in Table 80.
[0721] Table 80 shows the SL-U S-SSB MPR test scenario.
[0722] [Table 80]
[0723] Here, for the S-SSB {11 RBs}xN repeated RB position indices, "0" can mean that the starting RB index of {11 RBs} is 0. Furthermore, bitmap "1" can mean sending the corresponding RB set, and "0" can mean not sending the corresponding RB set for wideband operation.
[0724] Table 40 shows all possible bitmaps for subband configurations used in wideband operation. Wideband operation can be aggregated with multiple 20 MHz-based subbands. For SL-US-SSB MPR simulations, both continuous RB set bitmaps and non-contiguous RB set bitmaps can be considered.
[0725] Table 40 shows a bitmap of all possible RB sets for sub-band configurations.
