Title:
METHOD AND APPARATUS FOR RANDOM ACCESS PROCEDURE
Document Type and Number:
WIPO Patent Application WO/2021/172937
Kind Code:
A1
Abstract:
The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Methods and apparatuses for random access procedures in a wireless communication system. A method for operating a user equipment (UE) includes receiving a system information block (SIB) in a downlink bandwidth (DL) part (BWP). The DL BWP is linked to a first uplink (UL) BWP. The SIB includes an indication for one or more UL BWPs. The method further includes transmitting a physical random access channel (PRACH) in a second UL BWP from the one or more UL BWPs. The second UL BWP is different than the first UL BWP.
