Problems solved by technology

[0016] However, in the above-mentioned conventional mobile communication system, the mobile station MS cannot confirm the accuracy of timing synchronization involved in the transmission of the same information from a plurality of cells or the method of receiving information (for example, maximum ratio combining, selective combining, or There is no combination process), and the most suitable information receiving method cannot be selected, so there is a problem that with the deterioration of the reception quality in the mobile station MS, the transmission power of the base station BTS is increased, or the reception information in the mobile station MS is generated. duplication or loss of

Embodiment Construction

[0055] The mobile communication system in the first embodiment of the present invention

[0056] Figure 4 It is an overall configuration diagram showing the mobile communication system according to the first embodiment of the present invention. Such as Figure 4 As shown, the mobile communication system according to this embodiment has two base stations BTS1 and BTS2 under the control of the radio controller RNC.

[0057] In addition, when the mobile station MS moves from the cell 1 managed by the base station BTS1 to the cell 2 managed by the base station BTS2, or when the mobile station MS is in an area where signals from the cell 1 and the cell 2 can be received, the mobile station MS MS performs diversity handover between base station BTS1 and base station BTS2. In addition, in the mobile communication system of this embodiment, the mobile station MS performs broadcast communication or multicast communication.

[0058] In addition, in the following, in this specificat...

Abstract

It is possible to select an information selection method in a mobile station (MS) so as to evade increase of transmission power of a base station (BTS) or duplication or deficit of reception information in the mobile station (MS) when performing broadcast communication and multi-cast communication. The mobile station (MS) includes reception method selection information acquisition sections (11, 14, 15, 16) for acquiring reception method selection information for receiving the same information transmitted via a plurality of cells and a judgment section (12) for judging whether to perform a maximum ratio combination or a selection combination for the same information according to the reception selection information.

Description

technical field [0001] The present invention relates to a mobile communication system, a mobile station, and a wireless controller for transmitting the same information to a mobile station through a plurality of cells. Background technique [0002] In the existing second-generation mobile communication systems such as PDC (Personal Digital Cellular), the following handover (hand over) method (hard handover method: hard hand over) is adopted: when the mobile station is in the communication process between cells When moving, after the communication channel with the handover source cell is released, the communication channel with the handover destination cell is set up. [0003] On the other hand, in the existing CDMA mobile communication system, the following handover method (diversity handover (diversity handover)) is adopted: when the mobile station moves between cells during communication, Set up the communication channel with the handover target cell before the communicat...
