Document Type and Number:
WIPO Patent Application WO/2020/009488
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; and detecting a RA response message by monitoring the RA response message within a RA response window, wherein the RA response message includes an indicator indicating whether the payload is to be re-transmitted or not.
