1. A method for wireless communication, the method comprising:
- receiving, from a base station, information related to a starting position of an active state and information related to a length of a first timer;
deriving the starting position of the active state based on the information related to the starting position;
starting the first timer set to the length of the first timer and entering the active state at the derived starting position;
extending the active state, in response to control data indicating a new transmission of user data being received on a control channel; and
terminating the active state, based on a control signal indicating a termination of the active state and a second timer for extending the active state.

Abstract
A method and apparatus for controlling an active time period in a mobile communication system. The method includes transitioning to an active state from a sleep state; extending an active time of the active state, if control data indicating a transmission of new user data is received on a control channel; receiving a control signal indicating a termination of the active time; and transitioning to the sleep state from the active state, based on the control signal.

16. A method for wireless communication, the method comprising:
-
transmitting, by a base station, to a user equipment, information related to a starting position of an active state; and transmitting, by the base station, to the user equipment, control data on a control channel, the control data indicating a new transmission of user data, wherein a first timer is started at the starting position of the active state, and wherein the active state is extended, in response to the control data indicating the new transmission of the user data being received by the user equipment on the control channel, and wherein the active state is terminated by the user equipment based on a control signal indicating a termination of the active state and a second timer for extending the active state. - View Dependent Claims (17, 18, 19, 20, 21, 22)
