Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. There is disclosed a method, for a second base station in a network comprising a User Equipment (UE), a first base station, and the second base station. The method is for performing Random Access Channel (RACH)-less handover of the UE from the first base station to the second base station. The method comprises: obtaining a Conditional Handover (CHO) configuration (e.g., execution condition); determining a RACH-less Uplink (UL) grant configuration; transmitting, to the first base station, the RACH-less UL grant (e.g., in a HANDOVER REQUEST ACK message); and monitoring for UL RACH-less transmissions from the UE (e.g., a RRCConnectionReconfigurationComplete message) or scheduling Physical Downlink Control Channel (PDCCH) assignments to the UE, based on the CHO configuration.

Abstract: A method performed by a network control repeater (NCR) is provided. The method comprises determining whether a radio link failure (RLF) between the NCR and a first base station occurred. The method comprises, in case that the RLF between the NCR and the first base station occurred, performing cell selection for radio resource control (RRC) connection procedure. The method comprises, based on the result of the performing cell selection procedure, performing the RRC connection procedure with a selected base station.

Abstract: The disclosure relates to a 5th generation (5G) or 6th generation (6G) communication system for supporting a higher data transmission rate. A method performed by a user equipment (UE) in a wireless communication system is provided. The method includes receiving, from a base station, a first system information block (SIB) associated with satellite assistance information, the first SIB including first information on serving cell ephemeris and second information on a validity duration of the serving cell ephemeris, and receiving, from the base station, a second system information block (SIB) associated with neighbor satellite information based on a first timer with a duration of the validity duration of the serving cell ephemeris and a second timer for an acquisition of the first SIB before a radio link failure (RLF), the second SIB including third information on neighbor cell ephemeris.
