    摘要： A cell search control method, a mobile station and a mobile communications system can save consumption power with maintaining high accuracy for selecting a base station. The mobile station measures receiving quality (highest received power and the like) of a currently captured perch channel of a base station; automatically makes a decision as to whether the mobile station is located at a cell periphery in which the need for searching for a new perch channel is great, or located in neighborhood of a base station in which the need is little; and increases the frequency of the search at a location where the need is great and decreases it at a location where the need is little.

    摘要： A communication apparatus to be used for a newer system employing an FDD scheme in an area where an older system and the newer system coexist. The communication apparatus includes a first communication unit communicating at least a downlink data channel of the newer system using a frequency band belonging to a first frequency range (3.4-3.8 GHz); and a second communication unit communicating at least an uplink control channel of the newer system using a frequency band belonging to a second frequency range (2 GHz band) lower than the first frequency range. The second frequency range is used for uplink and downlink communications in the older system.

    摘要： A disclosed base station in a mobile communications system which uses a single-carrier technique for uplink includes a classifying unit which classifies, for each of multiple user apparatuses according to a path loss between the respective user apparatus and the base station, the multiple user apparatuses into two or more groups; and a scheduler which plans allocating of uplink resources to the user apparatuses. Uplink signals of each user apparatus that have multiple frequency components lined up in equal frequency intervals are multiplexed using a distributed frequency division multiplexing technique such that they are made mutually orthogonal on a frequency axis, the scheduler plans the resource allocating such that the user apparatuses belonging to different groups utilize different group bands or different time slots, and the group bands are specified by dividing a system band into groups.
