摘要： Influence on a key used between a user equipment and a base station, which will be imposed by unsecured updating of a key between the base station and a relay node when a relay node is being introduced is diminished. An HO request processing unit (202) extracts user equipment information from an HO request input from a receiver (201). A user equipment information determination section (204) determines a mode of handover from the user equipment information, and outputs a determination result to a key generator (205) and an HO command generator (207). In relation to a determination about a mode of handover on the basis of user equipment information, it is determined whether the handover is handover from a relay node to a base station, handover from a base station to a relay node, handover relating to relay nodes subordinate to the same base station, and the like. Then, preparation of handover command, updating of a key, and the like are performed in conformance with the mode of handover

摘要： In a wireless communication terminal in a wireless communication system for performing a control not to transmit signals, or to transmit signals with a reduction in a transmission power by a part of radio resources for a downlink signal in a cell provided by a base station, the terminal receives control information in generating a report related to a measurement result of the cell provided by the base station, monitors a state of a radio link with an own cell, and performs measurement on reception of the downlink signal. If an instruction for restricting the measurement to a part of the radio resources is included in the control information from the base station after the radio link failure occurs, the terminal generates and transmits a radio link failure report including the measurement result in the radio resources as instructed when the radio link failure occurs.

摘要： To make it possible for a legacy user equipment to correctly generate and use a common key between a user equipment and a base station and between the user equipment and a relay node when the relay nodes are being introduced. An HO request processing unit (202) extracts user equipment information from an HO request input from a receiver (201). A user equipment information determination section (204) determines a mode of handover from the user equipment information, and outputs a determination result to a key generator (205), a key information update request preparation section (206), and an HO command generator (207). In a case of handover from one base station to a relay node of another base station or to the other base station, the user equipment information determination section (204) commands the key information update request preparation section (206) to prepare a key information update request to a high-level management node so as to update the key information.

摘要： A wireless communication apparatus can communicate with a wireless communication base station using component carriers of communication cells managed by the wireless communication base station simultaneously. A radio condition determining section includes a physical layer problem determining section that determines whether a physical layer problem occurs in each component carrier which is used or can be used in communication between the wireless communication apparatus and the wireless communication base station. When it is determined that the physical layer problem occurs in some of the component carriers used in the communication, the radio condition determining section notifies the component carrier in which the physical layer problem occurs to a report creating section. The report creating section creates a report corresponding to the component carrier in which the physical layer problem occurs and a predetermined criterion.
