Title:
METHOD AND APPARATUS FOR TRANSMITTING A SIGNAL IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/139053
Kind Code:
A1
Abstract:
The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The present disclosure provides a method for operating a user equipment(UE) in wireless communication system. The method includes: receiving, from a base station, configuration information for a two-step random access transmission; determining a resource configuration for transmitting a first message of the two-step random access transmission based on the obtained configuration information for the two-step random access transmission, wherein the first message comprises a preamble and data; transmitting, to the base station, the first message according to the determined resource configuration; detecting a second message from the base station as a feedback of the first message; and performing a subsequent operation according to the detected second message.
