Title:
METHOD AND APPARATUS FOR PERFORMING MEASUREMENT BY USER EQUIPMENT IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/029502
Kind Code:
A1
Abstract:
The present invention relates to a method of performing a random access to a base station by a user equipment (UE) in a wireless communication system. In particular, the method includes transmitting a random access preamble and a payload including a common control channel (CCCH) service data unit (SDU) to the network; and receiving a medium access control (MAC) protocol data unit (PDU) in response to the random access preamble and the payload, wherein the MAC PDU includes a contention resolution identifier (CRID) and an indicator indicating a presence of a signaling radio bearer (SRB) radio resource control (RRC) message corresponding to the CRID in the MAC PDU.
