US 12,757,146 B2 · Registration procedure of sidelink terminal in wireless communication system

Abstract

The present disclosure relates to: a communication technique for merging IoT technology with a 5G communication system for supporting a data transmission rate higher than that of a 4G system; and a system therefor. The present disclosure can be applied to intelligent services (for example, smart homes, smart buildings, smart cities, smartcars or connected cars, healthcare, digital education, small businesses, security- and safety-related services, and the like) on the basis of 5G communication technology and IoT-related technology. The present disclosure relates to a method and a device for performing, on the basis of a sidelink in a wireless communication system, a RAN notification area (RNA) update operation of a remote terminal, in an RRC_INACTIVE state, connected to a relay.

Dependent claims

A method performed by a remote terminal in a wireless communication system, the method comprising:

receiving, from a first base station, via a first relay terminal, a radio resource control (RRC) release message including information on a suspend configuration;
entering an RRC inactive state, based on the information on the suspend configuration;
selecting a second relay terminal based on a relay reselection procedure in the RRC inactive state;
identifying whether a radio access network notification area (RNA) update (RNAU) is triggered, based on the selection of the second relay terminal;
and
in case that the RNAU is triggered, performing an RNAU procedure.
