Description

Beam measurement and reporting method and device The present disclosure generally relates to wireless communication systems, and more specifically, the present disclosure relates to a beam measurement and reporting method and apparatus. 5G mobile communication technologies define wide frequency bands to enable high transmission rates and new services, and can be implemented not only in "Sub 6GHz" bands such as 3.5GHz but also in "Above 6GHz" bands known as mmWave, which include 28GHz and 39GHz. In addition, the implementation of 6G mobile communication technologies (referred to as Beyond 5G systems) in terahertz bands (e.g., 95GHz to 3THz bands) has been considered to achieve transmission rates 50 times faster than 5G mobile communication technologies and ultra-low latency one-tenth that of 5G mobile communication technologies. In the early stages of development of 5G mobile communication technologies, in order to support services and meet performance requirements related to eMBB (enhanced Mobile BroadBand), URLLC (Ultra Reliable Low Latency Communications), and mMTC (massive Machine-Type Communications), standardization is underway regarding beamforming and massive MIMO to mitigate radio-wave path loss and extend transmission distances in mmWave, and new channel coding methods are being supported, such as numerologies for the efficient utilization of mmWave resources and dynamic operation of slot formats (e.g., operation of multiple subcarrier spacing), early access techniques for supporting multiple beam transmissions and broadbands, definition and operation of BWP (BandWidth Part), LDPC (Low Density Parity Check) codes for high-volume data transmission, polar codes for reliable transmission of control information, L2 pre-processing, and network slicing to provide dedicated networks specialized for specific services. Currently, discussions are underway regarding the improvement and performance enhancement of early 5G mobile communication technologies in terms of services to be supported by 5G mobile communication technologies, and physical layer standardization has been carried out for technologies such as V2X (Vehicle-to-everything), which aims to assist autonomous vehicles in making driving decisions and improve user convenience based on information regarding the location and status of vehicles transmitted by vehicles; NR-U (New Radio Unlicensed), which aims for system operations that meet various regulatory requirements for unlicensed bands; NR UE Power Saving; and NTN (Non-Terrestrial Network), which is UE-satellite direct communication for positioning that provides coverage in areas where communication with terrestrial networks is impossible. In addition, standardization of wireless interface architectures/protocols was underway regarding technologies such as IIoT (Industrial Internet of Things) to support new services through interworking and convergence with other industries, IAB (Integrated Access and Backhaul) to provide nodes for expanding network service areas by integrally supporting wireless backhaul links and access links, mobility enhancement technologies including conditional handover and DAPS (Dual Active Protocol Stack) handover, and Phase 2 Random Access (Phase 2 RACH for NR) to simplify random access procedures. Furthermore, standardization of system architectures/services was underway regarding 5G basic architectures (e.g., service-based architecture or service-based interface) to combine NFV (Network Functions Virtualization) and SDN (Software-Defined Networking) technologies, and MEC (Mobile Edge Computing) to receive services based on UE location. With the commercialization of 5G mobile communication systems, the exponentially increasing number of connected devices will be connected to communication networks. Consequently, it is expected that improvements in the functions and performance of 5G mobile communication systems and the integrated operation of connected devices will be necessary. To this end, new research is scheduled regarding 5G performance improvement and complexity reduction, AI service support, metaverse service support, and drone communication utilizing XR (eXtended Reality), Artificial Intelligence (AI), and Machine Learning (ML) to efficiently support AR (Augmented Reality), VR (Virtual Reality), and MR (Mixed Reality). In addition, the development of these 5G mobile communication systems will serve as a foundation for developing new waveforms to provide coverage of the terahertz bands of 6G mobile communication technologies, Full Dimensional MIMO (FD-MIMO), array antennas and large-scale antennas, metamaterial-based lenses and antennas to improve coverage of terahertz band signals, high-dimensional spatial multiplexing technology using Orbital Angular Momentus (OAM), and multiple antenna transmission technologies such as Reconfigurable Intelligent Surface (RIS), as well as full-duplex technology to increase frequency efficiency and improve system networks of 6G m
