Abstract: Methods and apparatuses are provided for monitoring a physical downlink control channel (PDCCH) in a wireless communication system. A UE receives a system information block (SIB) from a base station. The UE obtains a first time division duplex (TDD) uplink (UL)/downlink (DL) configuration from the SIB. The UE identifies DL subframes in a radio frame. The UE monitors the PDCCH transmitted from the base station on a DL subframe included in an on duration period of a discontinuous reception (DRX) cycle. The UE obtains information about a second TDD UL/DL configuration from the monitored PDCCH. The UE applies the second TDD UL/DL configuration to the radio frame. The DL subframe corresponds to a predetermined subframe number in the radio frame. The on duration period represents a period corresponding to a predetermined number of subframes from a subframe where the DRX cycle starts, and the on duration period is repeated periodically.

Abstract: A method and apparatus are provided for controlling an active state in a mobile communication system. The method includes 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. The second timer is started while the first timer is running, and the active state is terminated by the expiration of the second timer.

Abstract: A method and apparatus are provided for transmitting power headroom information by a terminal in a mobile communication system. The method includes receiving, by the terminal, information for an allocated uplink transmission resource; identifying whether a path loss has changed by more than a threshold, after transmitting last power headroom information, when the terminal has the allocated uplink transmission resource; in case that the path loss has changed by more than the threshold when the terminal has the allocated uplink transmission resource, determining a transmission of the power headroom information; and transmitting an uplink packet including the power headroom information based on the allocated uplink transmission resource. The power headroom information is obtained based on a difference between a maximum transmission power of the terminal and a transmission power of the terminal.
