<P>PROBLEM TO BE SOLVED: To provide a base station capable of continuing normal communication, even in the case where reception signals collide within continuous two slots, without performing any particular mounting or processing at a radio terminal side. <P>SOLUTION: A base station includes: a collision determination section for determining whether reception signals collide within continuous two slots; a calculation section for calculating a power level of the reception signal in a following slot, between the continuous two slots, and a delay time of the reception signal in the preceding slot when the collision determination section determines that the collision has occurred; a signal creation section for creating a reference signal having the power level calculated by the calculation section, by corresponding to a header section of the reception signal; and a signal extraction section for extracting the reception signal in the preceding slot by determining a colliding portion based on the delay time calculated, by the calculation section and subtracting the reference signal from a signal of the colliding portion. <P>COPYRIGHT: (C)2011,JPO&INPIT |
