Communication device

A communication device for performing wireless communication, comprising:

• a measurement-time holding unit which holds for measurement of delay profiles values of a measurement time in correspondence with values indicating one or a combination of a wireless condition or a service quality level;
• a change recognition unit which recognizes a change in at least one of the wireless condition and the service quality level, and notifies a measurement-time acquisition unit of the change;
• said measurement-time acquisition unit which acquires from said measurement-period holding unit a value of the measurement time corresponding to said change of which the measurement-time acquisition unit is notified by the change recognition unit;
• and
• a delay-profile measurement unit which performs the measurement of the delay profiles for the measurement time determined by said value acquired by the said measurement-time acquisition unit, within a time which is necessary and appropriate for the measurement.

A method for measuring delay profiles, comprising the steps of:

• (a) holding for measurement of the delay profiles values of a measurement period in correspondence with values indicating one or a combination of the number of spreading codes with which the delay profiles are to be measured and a measurement time which is determined for the measurement of the delay profiles according to reception quality;
• (b) recognizing a change in at least one of the number of spreading codes and the measurement time;
• (c) changing said measurement period according to said change;
• and
• (d) repeating the measurement of the delay profiles with the changed measurement period within a time which is necessary and appropriate for the measurement.
