Problems solved by technology

Therefore, such a system in which the relay station apparatus independently calculates the associated evaluation value for each mobile station apparatus cannot provide an optimal solution for the entire system.
In addition, calculating the evaluation values ​​complexly for all the mobile station devices related to a certain base station device requires a huge amount of computation.
As a result, not only the time required for calculation increases, but also the power consumption is wasted

Embodiment Construction

[0032] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

[0033] figure 1 It is a schematic diagram showing a mobile communication system according to an embodiment of the present invention.

[0034] In this embodiment, as an example, the number of base station devices is set to 1, the number of relay station devices (also referred to as "relay stations" in some cases) is set to 3, and the number of mobile station devices (also referred to as "terminals" in some cases, The case where the number of "communication terminals") is set to 6.

[0035] exist figure 1 Among them, a base station device 4 (the base station device may also be referred to as "BS") has a communication service area A. FIG. The base station apparatus 4 establishes connections with mobile station apparatuses 3-1 to 3-6 (the mobile station apparatuses may also be referred to as “MS”), or relay station apparatuses 2-1 to 2-3 (the relay station ap...

Abstract

This transmission channel selection method includes: collecting information for calculating evaluation values of a plurality of transmission channels; and calculating separate evaluation values of the transmission channels separately for a plurality of mobile stations. The number of candidates for the transmission channels for the mobile stations is reduced on the basis of the separate evaluation values. The information for calculating joint-separate evaluation values of transmission channels for at least one of the mobile stations is collected and the joint-separate evaluation values are calculated. The transmission channels for the mobile stations are selected on the basis of the separate evaluation values and the joint-separate evaluation values.

Description

technical field [0001] The present invention relates to a wireless communication system, a transmission path selection method, and a transmission path selection program. [0002] this application claims priority based on Japanese Patent Application No. 2010-262530 for which it applied to Japan on November 25, 2010, and uses the content here. Background technique [0003] Recent wireless communication systems are aimed at systems that provide new multimedia data communication services such as Internet connection functions, music distribution functions, video distribution functions, and electronic payment functions, compared with existing communication systems that are only used for calls. For this reason, higher radio quality is required, and the transmission power of the mobile station apparatus is limited due to constraints such as power supply capacity. Therefore, it is difficult to expand the wireless area covered by one base station device. For this purpose, the follow...
