Patent ID: 8259685

Claim:
A wireless communication method in a wireless communication system comprising a first wireless base station, a second wireless base station and a wireless terminal being able to communicate with said first wireless base station or said second wireless base station, said wireless communication method comprising: encoding a first signal to be transmitted to a first wireless zone at a first coding rate in said first wireless base station providing the first wireless zone, and transmitting the first signal at a first transmitting power from said first wireless base station to the first wireless zone; and encoding a second signal of a common channel to the first signal at a second coding rate lower than the first coding rate in said second wireless base station belonging to the first wireless zone and providing a second wireless zone, and transmitting the second signal at a second transmitting power from said second wireless base station to the second wireless zone, wherein a first code pattern for cell search according to the first coding rate is transmitted from said first wireless base station to the first wireless zone; a second code pattern for cell search according to the second coding rate is transmitted from said second wireless base station to the second wireless zone; and either one of the first code pattern and the second code pattern is detected by said wireless terminal processing the cell search to allow said wireless terminal to discriminate between the first coding rate and the second coding rate.
