Abstract
A communication controller capable of increasing the capacity of a downlink is provided. A CW length information extracting module-extracts information about the length of the bit stream of a CW (CW length) transmitted over an uplink and notifies it to a reception quality threshold setting module. The longer the notified CW length, the lower quality threshold Qth is set by the reception quality threshold setting module. The quality threshold set by the reception quality threshold setting module is multiplexed and notified with an output signal to be transmitted to abase station.
Claims31
A method for setting a quality threshold for a mobile communication system including a base station transmitting a common pilot signal by using predetermined power to one or more cells and a mobile station establishing a link to said base station in said one or more cells and measuring the reception quality of said common pilot signal transmitted from said base stations, comprising the step of:
- changing the quality threshold according to propagation circumstances between said base station and said mobile station.
A communication controller in a mobile communication system including a base station transmitting a common pilot signal by using predetermined power to one or more cells and a mobile station establishing a link to said base station in said one or more cells and measuring the reception quality of said common pilot signal transmitted from said base stations, said communication controller controlling said base station, said communication controller comprising:
- means for changing the quality threshold according to propagation circumstances between said base station and said mobile station.
