Title:

METHOD AND APPARATUS FOR OPERATING DRX TIMER BY USER EQUIPMENT IN WIRELESS COMMUNICATION SYSTEM

Document Type and Number:

WIPO Patent Application WO/2022/177249

Kind Code:

A1

Abstract:

The present disclosure relates to a method of transmitting a Medium Access Control (MAC) protocol data unit (PDU) by a user equipment (UE) in a wireless communication system. Especially, the method includes the steps of based on a first Medium Access Control (MAC) control element (CE) being triggered, transmitting, on a data uplink (UL) grant to a network, information indicating an amount of the first MAC CE to be transmitted; receiving a control UL grant from the network; constructing a MAC protocol data unit (PDU) including the first MAC CE; and transmitting the MAC PDU using the control UL grant.
