Document Type and Number:
WIPO Patent Application WO/2020/009487
Kind Code:
A1
Abstract:
The present invention relates to a method for performing a random access (RA) procedure by a user equipment (UE) in a wireless communication system. In particular, the method includes transmitting a RA preamble and a payload to a network; monitoring a first RA response (RAR) using a first identifier and a second RAR using a second identifier; if the first RAR is detected, re-transmitting the payload to the network; and if the second RAR is detected, considering a contention resolution successfully completed.
