Embodiment Construction

[0070] 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.

[0071] 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.

[0072] Here, the indistinguishability between the wireless signal d1 and the ...

Abstract

The occurrence of interference is suppressed to improve the quality of radio transmission. A radio station (1r) performs the communication of a radio signal (d1). A radio station (2r) receives a radio signal (d2) which cannot be discriminated from the radio signal (d1). A radio station (3r) is located in the radio communication range of the radio station (1r) and in the service area of the radio station (2r). A communication method converting section (21) generates a radio signal (d2a) which is obtained by converting the communication method of the radio signal (d2) into a communication method which can be discriminated from the radio signal (d1) to perform communication with the radio station (3r) by the radio signal (d2a).

Description

technical field [0001] The present invention relates to wireless communication systems. The wireless communication system includes, for example, a mobile station communication system and a wireless LAN (Local Area Network: Local Area Network). Background technique [0002] 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 addition, in 3GPP (3rd Generation Partnership Project: 3rd Generation Partnership Project) , the LTE-Advanced system, which is an improved version of LTE, is being discussed. [0003] Moreover, the purpose of the LTE-Advanced system is to propose it as an IMT-Advanced system, wherein the IMT-Advanced system is the IMT ( InternationalMobile Telecommunication: An improved version of the International Mobile Communication)-2000 system. [0004] In addition, as representatives of the IMT-2000 system, there ar...
