    • When detecting occurrence of an event for transmitting a measurement report of a radio condition of a cell at a frequency set for a base station apparatus, to the base station apparatus (3) communicating with a terminal apparatus (2), the terminal apparatus (2) in a wireless communication system (1) creates a measurement report including information indicating radio conditions of cells at a frequency at which the event occurred and at another different frequency. The base station apparatus (3) controls whether or not to perform handover of the terminal apparatus (2) to another cell, on the basis of the measurement report transmitted from the terminal apparatus (2). Thereby, there is provided a wireless communication system in which a base station apparatus and the terminal apparatus are communicable with each other using multiple frequencies, the wireless communication system being capable of shortening time required for handover.
    • 当检测到发送用于以基站装置设定的频率发送小区的无线条件的测量报告的事件发送到与终端装置(2)进行通信的基站装置(3)时,终端装置 )在无线通信系统(1)中创建测量报告,该测量报告包括指示事件发生的频率处的小区的无线电条件的信息和另一个不同的频率。 基站装置(3)基于从终端装置(2)发送的测量报告,控制是否对终端装置(2)进行切换。 因此,提供了一种无线通信系统,其中基站装置和终端装置可以使用多个频率彼此通信,该无线通信系统能够缩短切换所需的时间。

    • A terminal apparatus (1) which is a radio transmitting/receiving apparatus receives, from a femto cell base station (home eNB), a pilot channel signal for reception quality measurement and a synchronization channel signal for synchronization. The terminal apparatus (1) has a whitelist stored therein indicative of an accessible femto cell, and determines whether or not a CSG cell of handover destination is accessible based on a PCI of the CSG cell acquired from the synchronization channel and the whitelist. The terminal apparatus (1) then adds the PCI and a CGI to a measurement report for reception quality, and transmits the measurement report to a macro eNB (base station apparatus (2)). In this way, it is possible to suppress wasteful signaling and prevent unnecessary resources from being reserved even when two or more CSG cells that use the same PCI are present in the macro cell.
    • 作为无线发送接收装置的终端装置(1)从毫微微小区基站(家庭eNB)接收用于接收质量测量的导频信道信号和用于同步的同步信道信号。 终端装置(1)具有存储在其中的白名单,指示可访问的毫微微小区,并且基于从同步信道和白名单获取的CSG小区的PCI,确定切换目的地的CSG小区是否可访问。 终端装置(1)然后将PCI和CGI添加到测量报告中以用于接收质量,并将测量报告发送到宏eNB(基站装置(2))。 以这种方式,即使在宏小区中存在使用相同PCI的两个或更多个CSG小区,也可以抑制浪费的信令并防止不必要的资源被保留。
