Document Type and Number:
WIPO Patent Application WO/2022/114607
Kind Code:
A1
Abstract:
The present invention relates to a method of performing data transmission by a user equipment (UE) in a radio resource control (RRC) INACTIVE state at a wireless communication system. Especially, the method includes the steps of upon a reception of a Packet Data Convergence Protocol (PDCP) service data unit (SDU) from an upper layer, starting a discard timer related to the PDCP SDU; generating a medium access control (MAC) protocol data unit (PDU) including the PDCP SDU; starting a random access (RA) procedure for transmitting the MAC PDU; and based on the discard timer expiring before the RA procedure is completed, stopping the RA procedure.
