Title:
METHOD AND APPARATUS FOR L2 SL-BASED UE-TO-NETWORK RELAY OPERATIONS IN WIRELESS COMMUNICATION NETWORK
Document Type and Number:
WIPO Patent Application WO/2022/182207
Kind Code:
A1
Abstract:
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Methods and apparatuses for layer 2 (L2) sidelink (SL)-based user equipment (UE)-to-network relay operations in a wireless communication network. A method for operating a first UE includes receiving, from a second UE, a message including assistance information for a relay operation between the first UE and the second UE and receiving, from a base station (BS), a short message. The method further includes acquiring, based on information in the short message, first system information blocks including an earthquake and tsunami warning system/commercial mobile alert service (ETWS/CMAS) notification or second system information blocks for the second UE and transmitting, to the second UE over a sidelink channel, the acquired first system information blocks or the acquired second system information block.
