Abstract: A method and an apparatus for scheduling uplink transmissions according to a maximum transmission power and Power Headrooms (PHs) reported by a User Equipment (UE) are provided. A method for reporting the PHs for carriers used by a terminal in a mobile communication system supporting carrier aggregation includes generating a message including the PHs along with indicators indicating whether a real transmission is scheduled on an uplink data channel of corresponding carrier, and including, when the real transmission is scheduled, a maximum transmission power used for calculating the PHs in the generated message.

Abstract: The present invention pertains to a method and device for preserving mobility information in terminal state transition and effectively re-accessing in a heterogeneous cell network in a mobile communication system. A method for estimating a mobility state of a terminal in a mobile communication system according to one embodiment of the present invention may comprise the steps of: receiving, by the terminal, system information from a serving cell during an idle state; calculating mobility state information by using the received system information; storing the mobility state information; and transmitting the mobility state information to a base station when the terminal is connected to the base station. According to one embodiment of the present invention, when an idle state of a terminal is changed to a connection state in a mobile communication system, a mobility state of the terminal can be more effectively estimated.

Abstract: A method and base station in a wireless communication system are provided. The method includes transmitting, to a terminal, system information including information associated with a sub-frame configuration of multimedia broadcast multicast service single frequency network (MBSFN) sub-frames, identifying whether the transmission mode of the terminal is a first transmission mode or a second transmission mode, transmitting, to the terminal, dedicated message including configuration information of the identified transmission mode of the terminal, transmitting, to the terminal, control information in a physical downlink control channel (PDCCH) and data in a physical downlink shared channel (PDSCH) in a first sub-frame of the MBSFN sub-frames, if the terminal is configured in the first transmission mode, and transmitting, to the terminal, the control information in the PDCCH and the data in the PDSCH in a second sub-frame of a non-MBSFN sub-frames, if the terminal is configured in the second transmission mode.

Abstract: The present invention relates to a method and apparatus for transmitting data using a multi-carrier in a mobile communication system. The method of transmitting data in user equipment of a wireless communication system using a carrier aggregation technique according to an embodiment of the present invention includes setting secondary cells included in an S-TAG (Secondary-Timing Advance Group) configured of only secondary cells (SCells), deactivating a downlink timing reference cell in the S-TAG; determining whether other activated secondary cells exist besides the deactivated downlink timing reference cell in the S-TAG, and when the other activated secondary cells exist in the S-TAG, setting one of the other activated secondary cells as a new downlink timing reference cell. According to the present invention, uplink transmission speed can be increased in the user equipment and user QoS can be improved by transmitting data using one or more uplink carriers in the terminal.

Abstract: Methods and apparatuses are provided for Channel State Information (CSI) feedback. An Uplink (UL) grant is received from a Node B. Information included in the UL grant is identified. If the information is mapped to at least one DownLink (DL) Component Carrier (CC) based on configuration information relating to at least one set including the at least one DL CC, at least one CSI corresponding to the at least one DL CC is generated. The generated at least one CSI is transmitted to the Node B.
