Abstract  Abstract

A base station suitable for radio communications with a DS-CDMA mobile station
said mobile station comprising:
a spreading code generating unit configured to generate a spreading code based on a spreading factor;
a chip repetition unit configured to repeat a chip sequence after spread spectrum for a number of times; and
a phase sequence generating unit configured to generate at least one phase unique to the mobile station the phase being multiplied by the repeated chip sequences output by the chip repetition unit;

said base station being characterized by:
a control information determining unit configured
to determine control information that includes a spreading factor the number of chip repetitions and a phase unique to the mobile station based on information about a type of traffic; and
to transmit the spreading factor the number of chip repetitions and the unique phase of the mobile station that are determined to the mobile station.
