Description

Method and apparatus for performing cell measurement operation of over-the-air UE in next generation mobile communication system Technical Field The present disclosure relates to operation of a terminal and a base station in a mobile communication system. More particularly, the present disclosure relates to a method and apparatus for performing a cell measurement operation of an air UE (an analog UE) in a next generation mobile communication system. Background The 5G mobile communication technology defines a wide frequency band to achieve a high transmission rate and a new service, and can be implemented not only in a "below 6 GHz" frequency band such as 3.5GHz, but also in a "above 6 GHz" frequency band called mmWave including 28GHz and 39GHz frequency bands. Further, it has been considered to implement a 6G mobile communication technology (referred to as a super 5G system) in a terahertz frequency band (e.g., 95GHz to 3THz frequency band) to achieve a transmission rate fifty times faster than that of the 5G mobile communication technology and an ultra-low delay of one tenth of that of the 5G mobile communication technology. In the initial stage of 5G mobile communication technology, in order to support services and meet performance requirements related to enhanced mobile broadband (eMBB), ultra-reliable and low-delay communication (URLLC) and large-scale machine type communication (mMTC), standardization is underway regarding beamforming and massive MIMO for alleviating radio wave path loss and increasing radio wave transmission distances in mmWave, parameter sets for dynamic operation (e.g., operating a plurality of subcarrier intervals) for effectively utilizing mmWave resources and slot formats, initial access techniques for supporting multi-beam transmission and broadband, definition and operation of BWP (bandwidth part), new channel coding methods such as LDPC (low density parity check) codes for large-capacity data transmission and polarization codes for highly reliable transmission of control information, L2 preprocessing, and network slicing for providing a dedicated network customized for a specific service. Currently, in view of services that the 5G mobile communication technology will support, discussions on improvement and performance enhancement of the initial 5G mobile communication technology are underway, and there has been physical layer standardization on technologies such as vehicle-to-everything (V2X) for assisting driving determination of an autonomous vehicle based on information on the position and state of the vehicle transmitted by the vehicle, and for enhancing user convenience, new radio unlicensed (NR-U) aimed at system operation conforming to various regulatory-related requirements in unlicensed frequency bands, NR UE power saving, non-terrestrial network (NTN) which is UE-satellite direct communication for ensuring coverage in an area where communication with a terrestrial network is unavailable, and positioning. Further, standardization has also been underway regarding wireless interface architecture/protocol fields such as industrial internet of things (IIoT) for supporting new services through interworking and convergence with other industries, IAB (integrated access and backhaul) for providing nodes for network service area extension by supporting wireless backhaul links and access links in an integrated manner, mobility enhancement including conditional handover and DAPS (dual active protocol stack) handover, and two-step random access (2-step RACH) for simplifying a random access procedure. Standardization is also underway in the system architecture/service area for 5G baseline architecture (e.g., service-based architecture or service-based interface) for combining Network Function Virtualization (NFV) and Software Defined Network (SDN) technologies and for Mobile Edge Computing (MEC) for receiving services based on UE location. If such a 5G mobile communication system is commercialized, a connection device that has been exponentially increased will be connected to the communication network, and thus it is expected that enhanced functions and performance of the 5G mobile communication system and integrated operation of the connection device will be necessary. For this reason, new researches related to augmented reality (XR) have been arranged for effectively supporting Augmented Reality (AR), virtual Reality (VR), mixed Reality (MR), etc., 5G performance improvement and complexity reduction by using Artificial Intelligence (AI) and Machine Learning (ML), AI service support, metauniverse service support, and unmanned aerial vehicle communication. Further, such development of the 5G mobile communication system will be used not only as a basis for developing a new waveform for securing coverage in a terahertz band of the 6G mobile communication technology, full-dimensional MIMO (FD-MIMO), multi-antenna transmission technologies such as array antennas and large-scale antenn
