Title:
SYSTEM AND METHOD OF TRANSMITTING AND RECEIVING SYSTEM INFORMATION BY REDUCED CAPABILITY UES
Document Type and Number:
WIPO Patent Application WO/2023/048541
Kind Code:
A1
Abstract:
A method performed by a reduced capability user equipment (redcap UE) in a wireless communication system is provided. The method includes acquiring a system information block 1 (SIB1) including information on a first initial uplink bandwidth part (BWP) on a normal uplink (NUL) carrier, identifying whether the SIB1 includes first configuration information used for the redcap UE to request a system information (SI) message, identifying whether a second initial uplink BWP for the redcap UE is configured on the NUL carrier based on the SIB1, in a case that the SIB1 includes the first configuration information for the redcap UE, the second initial uplink BWP for the redcap UE is configured, and criteria to select the NUL carrier is met, starting a random access procedure for requesting the SI message in the second initial uplink BWP for the redcap UE on the NUL carrier, based on a preamble resource in the first configuration information, and acquiring the requested SI message.
