Embodiment Construction

[0071] Hereinafter, embodiments of the present invention will be described with reference to the drawings. figure 1 It is a diagram showing a configuration example of a wireless communication system. The wireless communication system 1 includes a wireless station (first wireless station) 1r, a wireless station (second wireless station) 2r, and a wireless station (third wireless station) 3r.

[0072] The wireless station 1r performs communication of the wireless signal (first wireless signal) d1. The wireless station 2r receives a wireless signal (second wireless signal) d2 scrambled to be indistinguishable from the wireless signal d1. Furthermore, the wireless station 2r includes a communication format conversion unit 21 . The wireless station 3r is located within the wireless communication range (service range) of the wireless station 1r and within the service range of the wireless station 2r.

[0073] Here, the indistinguishability between the wireless signal d1 and the ...

Abstract

The invention provides a wireless communication system and method, a relay station, a mobile station and a wireless device. By the adoption of the wireless communication system and method, the relay station, the mobile station and the wireless device, generation of interference is restrained so that the quality of wireless transmission can be improved. A wireless station (1r) conducts communication of a wireless signal (d1). A wireless station (2r) receives a wireless signal (d2) which cannot be distinguished from the wireless signal (d1). A wireless station (3r) is located within the wireless communication range of the wireless station (1r) and the service range of the wireless station (2r). A communication form conversion portion (21) generates a wireless signal (d2a) after the communication form of the wireless signal (d2) is converted to a communication form which can be distinguished from that of the wireless signal (d1), and the communication form conversion portion (21) conducts communication with the wireless station (3r) through the wireless signal (d2a).

Description

[0001] This application is a divisional application of an invention patent application with application number 200980154671.0 (international application number: PCT / JP2009 / 050775, filing date: January 20, 2009, invention name: wireless communication system). technical field [0002] The present invention relates to wireless communication systems. The wireless communication system includes, for example, a mobile communication system and a wireless LAN (Local Area Network: local area network). Background technique [0003] In recent years, there has been a new high-speed communication service called LTE (Long Term Evolution: Long Term Evolution) as a standard for mobile station communication such as mobile phones, and in 3GPP (3rd Generation Partnership Project: 3rd Generation Partnership Project) , the LTE-Advanced system, which is an improved version of LTE, is being discussed. [0004] Moreover, the purpose of the LTE-Advanced system is to be proposed as an IMT-Advanced sy...
