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： 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.

The invention is also providing apparatus and system for performing these methods, and computer readable media the instructions of which cause the apparatus and system to perform the methods described herein. In order to allow for aligning the timing of uplink transmissions on uplink component carriers, where different propagation delays are imposed on the transmissions on the uplink component carriers, the inventions suggests to time align the uplink component carriers based on a reference time alignment of a reference cell and a reception time difference or propagation delay difference between the downlink transmissions in the reference cell and the other radio cells, the uplink component carriers of which need to be time aligned.

摘要： A communication terminal is capable of simultaneously communicating through a plurality of carriers by carrier aggregation, and the communication terminal comprises: a quality measurement unit for measuring the reception quality of a radio wave transmitted through a plurality of carriers from a base station of a connected cell to obtain a measured value; a primary carrier storage unit storing information specifying a primary carrier chosen from the plurality of carriers; a comparator for comparing a measured value of the primary carrier measured by the quality measurement unit to a threshold value; and a cell search unit for searching for another cell when the measured value of the primary carrier is less than or equal to the threshold value. Consequently, a search threshold value for carrier aggregation can be appropriately determined to perform a cell search and a quality measurement.
