METHOD FOR PERFORMING RACH PROCEDURE BETWEEN TERMINAL AND BASE STATION, AND BASE STATION AND TERMINAL THEREFOR

WIPO Patent Application WO/2019/022314

A1

Disclosed is a 5th generation (5G) or pre-5G communication system for supporting a data transmission rate higher than that of a 4th generation (4G) communication system such as long term evolution (LTE). According to an embodiment of the present disclosure, when a base station performs a random access channel (RACH) procedure with a terminal, the base station can receive a random access (RA) preamble from the terminal, generate a random access response (RAR) message including an uplink grant allocated to the terminal, allocate a physical downlink control channel resource through which the generated RAR message is to be transmitted, transmit the RAR message to the terminal through the allocated physical downlink control channel resource, and receive a radio resource control (RRC) layer connection request message from the terminal through a resource allocated to the terminal by the uplink grant. The present research has been conducted with support from the "Cross-Departmental Giga-KOREA Project" funded by the government (Ministry of Science and ICT) in 2017.
