Inventor: TAKANO NAOKO
IPC: H04W24/10
Filed: 2002-02-12
Abstract: <P>PROBLEM TO BE SOLVED: To provide a communication controller capable of increasing line capacity of a downlink.  <P>SOLUTION: A CW (continuous wave) length information extraction part 311 extracts information regarding length (CW length) of CWs to be transmitted in an uplink and gives the information to a reception quality threshold setting part 312. In this case, the longer the informed CW length is, the less a quality threshold Qth is set in the reception quality threshold setting part 312. The quality threshold Qth determined by the reception quality threshold setting part 312 is multiplexed to an output signal to be transmitted to a base station and the base station is informed of it.  <P>COPYRIGHT: (C)2003,JPO
