摘要： A method for supporting activation/deactivation of serving cells by a base station (BS) in a wireless communication system provides decreased overhead and decreased power consumption for a user equipment (UE). The method includes configuring M supportable serving cells in the UE, configuring an indicator indicating activation/deactivation of each of the M serving cells, configuring a medium access control (MAC) message which includes a MAC control element (CE) and a logical channel identifier (LCID), the MAC CE including the indicator configured for each of the M serving cells and having a length corresponding to an integer multiple of 8 bits, the LCID indicating that the MAC CE includes the indicator indicating activation/deactivation of each serving cell, and transmitting the configured MAC message to the UE. Accordingly, a control channel or data channel regarding a component carrier is selectively received depending on whether the component carrier is activated.

摘要： The present invention relates to an apparatus and method for controlling uplink transmission power in a multiple element carrier wave system. The method for controlling uplink transmission power by a terminal in a multiple element carrier wave system includes the steps of: generating an uplink signal to be transmitted in a first serving cell; receiving, from a base station, random access start information for commanding the start of a random access procedure for a second serving cell; calculating the estimated surplus power from first transmission power scheduled for an uplink signal transmission, and second transmission power scheduled for a transmission of a PRACH to which a random access preamble is mapped; and when the estimated surplus power is smaller than a threshold power, adjusting the first transmission power or the second transmission power on the basis of power allocation priority.

摘要： The present invention provides an apparatus and a method for controlling coexistence interference within a device in a wireless communication system. The method discloses the following steps: performing triggering, in which a transmission, which is generated in a terminal, in a first frequency band of a first network system requests controlling of interference on a reception, which is generated in the terminal, in a second frequency band of a second network system; transmitting to a base station support information including information on a time section that can or cannot be used by the first network system of the second network system, due to the interference; and receiving from the base station reply information for accepting or denying interference control as a reply to the support information.

摘要： The present invention relates to an apparatus and a method for performing measurement reporting considering in-device coexistence interference. The present invention provide a user equipment transmitting a measurement report in a wireless communication system, comprising an interference detection unit, an assistant information generation unit, a measurement controller and a transmitter. According to the present invention, a measurement procedure can be clearly defined in an interference delicate band where in-device coexistence interference occurs and scheduling restrictions on an eNodeB due to measurement reporting about an interference delicate band can be reduced.
