Abstract: A method and apparatus for transmitting an uplink indication for extended discontinuous reception (eDRX) in a wireless communication system is provided. A user equipment (UE) detects that an event related to eDRX occurs, and transmits an uplink indication related to eDRX to a network. When the event related to eDRX is that an eDRX timer expires or an eDRX command indicating stop of eDRX is received, the uplink indication may indicate stop of eDRX. When the event related to eDRX is that no uplink data is to be transmitted, the uplink indication may indicate start of eDRX.
