WIRELESS COMMUNICATION SYSTEM

摘要

There is provided a wireless communication system that is capable of preventing interference with a primary use system caused by a CPE emitting radio waves at a frequency which is not a transmittable frequency before acquiring a list of transmittable frequencies based on its position information. In a wireless communication system that uses white space, a BS 10 and a CPE 22 store a specific frequency which is guaranteed to not interfere with a primary user. The BS 10 regularly switches between a first period when communication is performed at an operating frequency that uses white space and a second period when communication is performed at the specific frequency. In a case where whether the operating frequency is a transmittable frequency of the CPE 22 is not known, the CPE 22 performs communication with the base station at the specific frequency in the second period, and in a case where the operating frequency is recognized as the transmittable frequency, the CPE 22 performs communication at the operating frequency in the first period, and performs communication at the specific frequency in the second period.

1. A wireless communication system for performing wireless communication between a base station and a terminal station by using white space,
wherein the base station and the terminal station store information about a specific frequency that is guaranteed to not interfere with a primary user, the base station performs communication while regularly switching between a first period when communication is performed at an operating frequency that uses the white space and a second period when communication is performed at the specific frequency, and in a case where whether the operating frequency is a transmittable frequency that is based on position information of the terminal station is not recognized by the terminal station, the terminal station performs communication with the base station at the specific frequency in the second period, and in a case where the operating frequency is recognized as the transmittable frequency that is based on the position information of the terminal station, the terminal station performs communication with the base station at the operating frequency in the first period, and performs communication with the base station at the specific frequency in the second period.
