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.

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： This specification relates to an apparatus and method for performing random access in a wireless communication system. This specification discloses a mobile station, including a reception unit for receiving TAG configuration information on which at least one serving cell configured in the mobile station is classified as a Timing Alignment Group (TAG) from a base station and a transmission unit for transmitting a random access preamble to the base station on one representative serving cell within the TAG. In accordance with this specification, a procedure of obtaining a TAV for a serving cell in order to secure and maintain uplink timing synchronization becomes clear, the time taken to obtain uplink synchronization for a serving cell may be reduced, and overhead due to excessive random access attempts may be reduced by obtaining a TAV for a plurality of serving cells through one random access procedure.

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： A method and an apparatus for controlling in-device coexistence interference (IDC) in a wireless communication system are provided. The present invention comprises transmitting IDC indication information including an unusable frequency band that is a frequency band in which performing communication is difficult because of IDC interference to a Base Station (BS), receiving Radio Resource Control (RRC) connection reconfiguration including IDC Discontinuous Reception (DRX) configuration reconfiguring DRX relating the unusable frequency band based on the IDC indication information from the BS and performing autonomously denial of Industrial Scientific Medical (ISM) transmission in the unusable frequency band by reconfiguring DRX based on the IDC DRX configuration.

摘要： Method and apparatus for controlling in-device coexistence (IDC) interference in a wireless communication system are described in the present invention. The present invention includes transmitting UE capability information whether the UE has a capability to measure IDC, to a base station (BS); receiving measurement configuration information whether the UE is allowed to send IDC indication, from the BS; and transmitting the IDC indication and at least one of measurements which are a measurement in consideration of IDC and a measurement without consideration of IDC to the BS. It is possible to control reducing occurrence of in-device coexistence interference.
