METHOD AND APPARATUS FOR CONFIGURATION AND REPORTING IN A WIRELESS COMMUNICATION SYSTEM

[0001] The present application relates to wireless communication technology, and in particular to a method and apparatus for measurement configuration and / or reporting of quality-of-experience.

[0002] 5G mobile communication technologies define broad frequency bands such that high transmission rates and new services are possible, and can be implemented not only in “Sub 6GHz” bands such as 3.5GHz, but also in “Above 6GHz” bands referred to as mmWave including 28GHz and 39GHz. In addition, it has been considered to implement 6G mobile communication technologies (referred to as Beyond 5G systems) in terahertz (THz) bands (for example, 95GHz to 3THz bands) in order to accomplish transmission rates fifty times faster than 5G mobile communication technologies and ultra-low latencies one-tenth of 5G mobile communication technologies.

[0003] At the beginning of the development of 5G mobile communication technologies, in order to support services and to satisfy performance requirements in connection with enhanced Mobile BroadBand (eMBB), Ultra Reliable Low Latency Communications (URLLC), and massive Machine-Type Communications (mMTC), there has been ongoing standardization regarding beamforming and massive MIMO for mitigating radio-wave path loss and increasing radio-wave transmission distances in mmWave, supporting numerologies (for example, operating multiple subcarrier spacings) for efficiently utilizing mmWave resources and dynamic operation of slot formats, initial access technologies for supporting multi-beam transmission and broadbands, definition and operation of BWP (BandWidth Part), new channel coding methods such as a LDPC (Low Density Parity Check) code for large amount of data transmission and a polar code for highly reliable transmission of control information, L2 pre-processing, and network slicing for providing a dedicated network specialized to a specific service.

[0004] Currently, there are ongoing discussions regarding improvement and performance enhancement of initial 5G mobile communication technologies in view of services to be supported by 5G mobile communication technologies, and there has been physical layer standardization regarding technologies such as V2X (Vehicle-to-everything) for aiding driving determination by autonomous vehicles based on information regarding positions and states of vehicles transmitted by the vehicles and for enhancing user convenience, NR-U (New Radio Unlicensed) aimed at system operations conforming to various regulation-related requirements in unlicensed bands, NR UE Power Saving, Non-Terrestrial Network (NTN) which is UE-satellite direct communication for providing coverage in an area in which communication with terrestrial networks is unavailable, and positioning.

[0005] Moreover, there has been ongoing standardization in air interface architecture / protocol regarding technologies 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 a node for network service area expansion by supporting a wireless backhaul link and an access link in an integrated manner, mobility enhancement including conditional handover and DAPS (Dual Active Protocol Stack) handover, and two-step random access for simplifying random access procedures (2-step RACH for NR). There also has been ongoing standardization in system architecture / service regarding a 5G baseline architecture (for example, service based architecture or service based interface) for combining Network Functions Virtualization (NFV) and Software-Defined Networking (SDN) technologies, and Mobile Edge Computing (MEC) for receiving services based on UE positions.

[0006] As 5G mobile communication systems are commercialized, connected devices that have been exponentially increasing will be connected to communication networks, and it is accordingly expected that enhanced functions and performances of 5G mobile communication systems and integrated operations of connected devices will be necessary. To this end, new research is scheduled in connection with eXtended Reality (XR) for efficiently supporting AR (Augmented Reality), VR (Virtual Reality), MR (Mixed Reality) and the like, 5G performance improvement and complexity reduction by utilizing Artificial Intelligence (AI) and Machine Learning (ML), AI service support, metaverse service support, and drone communication.

[0007] Furthermore, such development of 5G mobile communication systems will serve as a basis for developing not only new waveforms for providing coverage in terahertz bands of 6G mobile communication technologies, multi-antenna transmission technologies such as Full Dimensional MIMO (FD-MIMO), array antennas and large-scale antennas, metamaterial-based lenses and antennas for improving coverage of terahertz band signals, high-dimensional space multiplexing technology using OAM (Orbital Angular Momentum), and RIS (Reconfigurable Intelligent Surface), but also full-duplex technology for increasing frequency efficiency of 6G mobile communication technologies and improving system networks, AI-based communication technology for implementing system optimization by utilizing satellites and AI (Artificial Intelligence) from the design stage and internalizing end-to-end AI support functions, and next-generation distributed computing technology for implementing services at levels of complexity exceeding the limit of UE operation capability by utilizing ultra-high-performance communication and computing resources.

Those skilled in the art will understand that the principles of the present disclosure may be implemented in any suitably arranged system or device.

[0075] FIG. 1 is an exemplary system architecture 200 according to various embodiments of the present disclosure. Other embodiments of the system architecture 200 could be used without departing from the scope of the present disclosure. The user equipment (UE) 201 is a terminal device to receive data. The Next Generation Radio Access Network (NG-RAN) 202 is a radio access network that includes a base station (gNB or eNB connected to the 5G core network 5GC, eNB connected to 5GC also called ng-gNB) that provides an access wireless network interface for a UE. The Access Control and Mobility Management Function (AMF) 203 is responsible for managing the mobility context of the UE, and security information.

The data network (DN) 206 includes services such as operators, access to the Internet, and traffic for third parties, among others.

[0076] In the NR system, in order to support network function virtualization, more efficient resource management and scheduling, a base station (gNB / ng-eNB) providing a wireless network interface for a terminal (UE) may be further divided into a centralized unit gNB-CU / ng-eNB-CU (gNB central unit / ng-eNB central unit) and a distributed unit gNB-DU / ng-eNB-DU (gNB distributed unit / ng-eNB distributed unit) (simply referred to as CU and DU in the present disclosure), as shown in FIG. 2 (a). The gNB-CU has Radio Resource Control (RRC), Service Data Adaptation Protocol (SDAP) and Packet Data Convergence Protocol (PDCP) protocol layers, etc., and the ng-eNB-CU has an RRC layer and a PDCP layer. The gNB-DU / ng-eNB-DU has Radio Link Control Protocol (RLC), Medium Access Control (MAC), and Physical layers, among others. The interface between gNB-CU and gNB-DU is a standardized public interface F1 and between ng-eNB-CU and ng-eNB-DU is a standardized public interface W1. The F1 interface includes the control plane F1-C and the user plane F1-U. The transport network layer of F1-C is based on IP transport. For more reliable transport signaling, the SCTP protocol was added on top of IP. The protocol of the application layer is F1AP (F1 interface application protocol), see 3GPP TS 38. 473. SCTP may provide reliable application layer message transmission. The transport layer of F1-U is UDP / IP and GTP-U is used on top of UDP / IP for carrying user plane protocol data units, i.e., PDUs. Further, for a gNB-CU, as shown in FIG. 2 (b), the gNB-CU may include a gNB-CU-CP (control plane part of the centralized unit of the base station) containing the control plane functions of the base station with RRC and PDCP protocol layers and a gNB-CU-UP (user plane part of the centralized unit of the base station) containing the user plane functions of the base station with SDAP and PDCP protocol layers. The interface between gNB-CU-CP and gNB-CU-UP is a standardized public interface E1 and the protocol is E1AP, see 3GPP TS 38. 463. The interface between the control plane part of the centralized unit of the base station and the distributed unit of the base station is the F1-C interface, i.e. the control plane interface of F1, and the interface between the user plane part of the centralized unit of the base station and the distributed unit of the base station is the F1-U interface, i.e. the user plane interface of F1. In addition, in the NR system, a base station providing the E-UTRA user plane and control plane accessing the 5G core network is called ng-eNB, and in order to support virtualization, such a base station (ng-eNB) may also be further divided into a centralized unit ng-eNB-CU (gNB central unit / ng-eNB central unit) and a distributed unit ng-eNB-DU (gNB distributed unit / ng-eNB distributed unit) (simply referred to as CU and DU in the present disclosure), as shown in FIG. 2 (c). The ng-eNB-CU has an RRC, PDCP layer. The gNB-DU / ng-eNB-DU has Radio Link Control Protocol (RLC), Medium Access Control (MAC), and Physical layers, among others. The interface between the ng-eNB-CU and the ng-eNB-DU is a standardized public interface W1. The W1 interface includes the control plane W1-C and the user plane W1-U. The transport network layer of W1-C is based on IP transport. For more reliable transport signaling, the SCTP protocol was added on top of IP.
