    • For lack of a unique, specific and detailed specification for information on status of a mobile station to be notified by a mobile station to a fixed station, an operation may be varied from one mobile station to another in a communication system, thereby posing a problem for an efficient uplink scheduling. A communication method includes a transmission process multiplexing a transport channel for transmitting data from a high-order layer on a physical data channel and transmitting the multiplexed result to the fixed station, a status notification process notifying status information containing information on a transmission power headroom used for scheduling, and a transmission control process receiving the scheduling result and controlling the transmission process. The status information notification process includes notifying an index attached to each predetermined transmission power headroom level classified between upper and lower limit values of the transmission power headroom as the status information.
    • 由于对于要由移动台向固定站通知的移动站的状态的信息缺乏唯一的,具体和详细的​​规范,所以在通信系统中可以从一个移动站到另一个移动站的操作变化,从而造成问题 用于高效的上行链路调度。 通信方法包括:传输处理,多路复用用于从物理数据信道上的高阶层发送数据的传输信道,并将多路复用结果发送到固定站;状态通知过程,通知包含使用的传输功率余量的信息的状态信息 以及接收调度结果并控制发送处理的发送控制处理。 状态信息通知处​​理包括通知附加到分配在发送功率余量的上限值和下限值之间的每个预定发送功率余量水平的索引作为状态信息。

    • There is a problem that when a closed subscriber group (CSG) cell available to subscribers is installed in a macro cell area, communication cannot be performed due to the interference between a macro cell and the CSG cell in an area thereof. The CSG cell that is provided in the CSG cell area and transmits a downlink synchronization signal using a radio frame assigns control signals to a first subframe and a second subframe among a plurality of subframes constituting the radio frame, and the macro cell that is provided in the macro cell area and transmits a downlink synchronization signal using the radio frame assigns control signals to a third subframe and a fourth subframe, which are shifted from the first subframe and the second subframe by a predetermined number of subframes, respectively, among the plurality of subframes constituting the radio wave, the CSG cell and the macro cell being configured to perform transmission in synchronization with each other.
    • 存在如下问题:当在宏小区区域中安装可用于用户的封闭用户组(CSG)小区时,由于宏小区与CSG小区在其区域中的干扰,不能执行通信。 设置在CSG小区区域中并且使用无线帧发送下行链路同步信号的CSG小区将控制信号分配给构成无线帧的多个子帧中的第一子帧和第二子帧,并且设置在 宏小区区域并且使用无线帧发送下行链路同步信号,将控制信号分配给分别从第一子帧和第二子帧移位预定数量的子帧的第三子帧和第四子帧 构成无线电波的子帧,CSG小区和宏小区被配置为彼此同步地进行发送。

    • In a mobile communication system according to the present invention, with the separate use of a plurality of component carriers or with the use of a carrier set including the plurality of component carriers aggregated, a base station performs radio communication with a user equipment corresponding to the component carrier or a user equipment corresponding to the aggregated carriers. In particular, in a case where the base station performs radio communication with the user equipment corresponding to the aggregated carriers with the use of the aggregated carriers, each of a plurality of transport blocks created by dividing a transport channel is transmitted per each of the plurality of component carriers constituting the aggregated carriers, and control information related to radio communication between the base station and the user equipment corresponding to the aggregated carriers is transmitted such that physical information of the corresponding component carrier is identifiable.
    • 在根据本发明的移动通信系统中,通过单独使用多个分量载波,或者使用聚合了多个分量载波的载波集合,基站与对应于多个分量载波的用户设备进行无线通信 分量载波或对应于聚合载波的用户设备。 特别地,在基站使用聚合载波对与聚合载波对应的用户设备进行无线通信的情况下,通过划分传输信道而创建的多个传输块中的每一个被传送到多个 构成聚合载波的分量载波,并且发送与基站和对应于聚合载波的用户设备之间的无线电通信有关的控制信息,使得相应分量载波的物理信息是可识别的。
