Description

NODE IN COMMUNICATION SYSTEM AND METHOD PERFORMED THEREOF

[0001] The present disclosure relates to the field of communication, and more specifically, to a method performed by a first node in a communication system, a method performed by a second node in a communication system, a method performed by a third node in a communication system, a method performed by a fourth node in a communication system, a method performed by a user equipment (UE) in a communication system, a first node, a second node, a third node, a fourth node, and user equipment.

[0002]

[0003] Considering the development of wireless communication from generation to generation, the technologies have been developed mainly for services targeting humans, such as voice calls, multimedia services, and data services. Following the commercialization of 5G (5th-generation) communication systems, it is expected that the number of connected devices will exponentially grow. Increasingly, these will be connected to communication networks. Examples of connected things may include vehicles, robots, drones, home appliances, displays, smart sensors connected to various infrastructures, construction machines, and factory equipment. Mobile devices are expected to evolve in various form-factors, such as augmented reality glasses, virtual reality headsets, and hologram devices. In order to provide various services by connecting hundreds of billions of devices and things in the 6G (6th-generation) era, there have been ongoing efforts to develop improved 6G communication systems. For these reasons, 6G communication systems are referred to as beyond-5G systems.

[0004] 6G communication systems, which are expected to be commercialized around 2030, will have a peak data rate of tera (1,000 giga)-level bps and a radio latency less than 100μsec, and thus will be 50 times as fast as 5G communication systems and have the 1 / 10 radio latency thereof.

[0005] In order to accomplish such a high data rate and an ultra-low latency, it has been considered to implement 6G communication systems in a terahertz band (for example, 95GHz to 3THz bands). It is expected that, due to severer path loss and atmospheric absorption in the terahertz bands than those in mmWave bands introduced in 5G, technologies capable of securing the signal transmission distance (that is, coverage) will become more crucial. It is necessary to develop, as major technologies for securing the coverage, radio frequency (RF) elements, antennas, novel waveforms having a better coverage than orthogonal frequency division multiplexing (OFDM), beamforming and massive multiple input multiple output (MIMO), full dimensional MIMO (FD-MIMO), array antennas, and multiantenna transmission technologies such as large-scale antennas. In addition, there has been ongoing discussion on new technologies for improving the coverage of terahertz-band signals, such as metamaterial-based lenses and antennas, orbital angular momentum (OAM), and reconfigurable intelligent surface (RIS).

[0006] Moreover, in order to improve the spectral efficiency and the overall network performances, the following technologies have been developed for 6G communication systems: a full-duplex technology for enabling an uplink transmission and a downlink transmission to simultaneously use the same frequency resource at the same time; a network technology for utilizing satellites, high-altitude platform stations (HAPS), and the like in an integrated manner; an improved network structure for supporting mobile base stations and the like and enabling network operation optimization and automation and the like; a dynamic spectrum sharing technology via collison avoidance based on a prediction of spectrum usage; an use of artificial intelligence (AI) in wireless communication for improvement of overall network operation by utilizing AI from a designing phase for developing 6G and internalizing end-to-end AI support functions; and a next-generation distributed computing technology for overcoming the limit of UE computing ability through reachable super-high-performance communication and computing resources (such as mobile edge computing (MEC), clouds, and the like) over the network. In addition, through designing new protocols to be used in 6G communication systems, developing mecahnisms for implementing a hardware-based security environment and safe use of data, and developing technologies for maintaining privacy, attempts to strengthen the connectivity between devices, optimize the network, promote softwarization of network entities, and increase the openness of wireless communications are continuing.

[0007] It is expected that research and development of 6G communication systems in hyper-connectivity, including person to machine (P2M) as well as machine to machine (M2M), will allow the next hyper-connected experience. Particularly, it is expected that services such as truly immersive extended reality (XR), high-fidelity mobile hologram, and digital replica could be provided through 6G communication systems. In addition, services such as remote surgery for security and reliability enhancement, industrial automation, and emergency response will be provided through the 6G communication system such that the technologies could be applied in various fields such as industry, medical care, automobiles, and home appliances.

[0008] Wireless communication is one of the most successful innovations in modern history. Recently, a number of subscribers of wireless communication services has exceeded 5 billion, and it continues growing rapidly. With the increasing popularity of smart phones and other mobile data devices (such as tablet computers, notebook computers, netbooks, e-book readers and machine-type devices) in consumers and enterprises, a demand for wireless data services is growing rapidly. In order to meet rapid growth of mobile data services and support new applications and deployments, it is very important to improve efficiency and coverage of wireless interfaces.

[0061] In NR system, in order to support network function virtualization, more efficient resource management and scheduling, a base station (gNB / ng-eNB) that provides a radio network interface for user equipment (UE) can 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) (abbreviated as CU and DU in the present invention), as shown in Figure 3(a).

[0062] gNB-CU has radio resource control (RRC), service data adaptation protocol (SDAP) and packet data convergence protocol (PDCP) protocols, etc, while ng-eNB-CU has RRC and PDCP layers. gNB-DU / ng-eNB-DU has radio link control protocol (RLC), medium access control (MAC) and physical layer, etc. There is a standardized public interface F1 between gNB-CU and gNB-DU, and a standardized public interface W1 between ng-eNB-CU and ng-eNB-DU.

[0063] In order to transmit signaling more reliably, SCTP (stream control transmission protocol) protocol is added to IP. The protocol of the application layer is F1AP (F1 Application Protocol, F1 Application Protocol / F1 Interface Application Protocol), see 3GPP TS38.473. SCTP can provide reliable application layer message transmission. The transport layer of F1-U (F1-User, user plane of F1) is UDP / IP, and GTP-U (GPRS tunneling protocol for the user plane) is used to carry user plane protocol data unit PDU above UDP / IP.

[0065] The interface between the control plane part of the centralized unit of the base station and the distributed unit of the base station is F1-C interface, that is, 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 F1-U interface, that is, the user plane interface of F1. In addition, in the NR system, the base station providing the E-UTRA user plane and control plane which accesses the 5G core network is called ng-eNB.

[0066] In order to support virtualization, such a base station (ng-eNB) can 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) (abbreviated as CU and DU in the present invention), as shown in Figure 3(c). ng-eNB-CU has RRC and PDCP layers. gNB-DU / ng-eNB-DU has radio link control protocol (RLC), medium access control (MAC) and physical layer,etc. There is a standardized public interface W1 between ng-eNB-CU and ng-eNB-DU. W1 interface is divided into control plane W1-C and user plane W1-U. The transport network layer of W1-C is based on IP transport. In order to transmit signaling more reliably, SCTP protocol is added to IP. The protocol of the application layer is W1AP, see 3GPP TS37.473. The transport layer of W1-U is UDP / IP, and GTP-U is used to carry user plane protocol data unit PDU above UDP / IP.
