Embodiment Construction
[0022] Hereinafter, a mobile communication system according to an embodiment will be described with reference to the drawings.
[0023] In this mobile communication system, the base station apparatus notifies the mobile station apparatus in wireless communication of the cells available for communication with the mobile station apparatus in the cells set by the own apparatus via any one of a plurality of cells set by the own apparatus. The identification number of the district. When the mobile station device measures the radio strength and quality of the cell to add a cell that can be used for communication with the base station device in wireless communication, only for the cell having the identification number that matches the identification number notified from the base station device , report the identification number of the cell to the base station apparatus.
[0024] This embodiment employs, for example, a mobile communication system based on LTE-Advanced. However, this...

Provided is a mobile communication system including a base station device and a mobile station device configured with a plurality of cells. In this mobile communication system, the base station apparatus notifies, to a mobile station apparatus communicating via a first cell among the plurality of cells, identification information of at least one of the plurality of cells that can be used for communication with the mobile station apparatus, and Instructs the mobile station device communicating via the first cell to measure the reception state of the radio signal. On the other hand, the mobile station apparatus detects a cell that transmits a radio signal receivable by the mobile station apparatus based on an instruction from the base station apparatus, and when the identification information of the detected cell matches at least one of the identification information of the cell , notifying the base station apparatus of the identification information of the detected cell.
Description
technical field [0001] The present invention relates to a measurement method for a mobile station apparatus to detect a cell while communicating via any one of a plurality of cells set by a base station apparatus, and a mobile communication system, mobile station apparatus, and base station apparatus that implement such a measurement method. Background technique [0002] In mobile communication systems, applications that communicate large volumes of data, such as applications that stream video data, are used. Therefore, techniques for increasing data communication speed in mobile communication systems have been studied. For example, as an example of such a technology, Coordinated multi-point transmission / reception (CoMP) technology using multiple cells for communication at the same time and Carrier Aggregation (Carrier Aggregation) technology using multiple frequency bands for communication at the same time have been proposed. Aggregation (CA)). CoMP and CA technologies ar...
