Wireless communication system and frequency hopping method therefor, and base station and mobile station

A frequency hopping method for a wireless communication system to which frequency hopping is applied, comprising the steps of:

• changing, in a receiving side device, a frequency hopping cycle from a regular cycle to a measuring period so that the receiving side device can measure a phase shift amount of a received signal;
• determining, in the receiving side device, a transmit frequency from a transmitting side device;
• and
• generating, in the receiving side device, a control signal to notify the transmitting side device of the transmit frequency.

A base station for a wireless communication system to which frequency hopping is applied, comprising:

• a setting means for changing a frequency hopping cycle from a regular cycle to a measuring period so that the base station can measure a phase shift amount of a received signal;
• a transmit frequency determination means for determining a transmit frequency from a mobile station;
• and
• a control signal generation means for generating a control signal to notify the mobile station of the transmit frequency.

A mobile station for a wireless communication system to which frequency hopping is applied, a frequency hopping cycle being changed from a regular cycle to a measuring period so that a base station can measure a phase shift amount of a received signal,

• the mobile station comprising:
• a transmit frequency information extraction means for extracting transmit frequency information from a control signal transmitted from the base station;
• and
• a transmit modulation frequency determination means for determining a transmit modulation frequency based on the transmit frequency information.

A computer program product stored on a non-transitory tangible computer readable medium causing a computer to execute a frequency hopping method for a wireless communication system to which frequency hopping is applied, causing a computer of a receiving side device to execute the steps of:

• changing a frequency hopping cycle from a regular cycle to a measuring period so that the receiving side device can measure a phase shift amount of a received signal;
• determining a transmit frequency from a transmitting side device;
• and
• generating a control signal to notify the transmitting side device of the transmit frequency.
