ABSTRACT:
In order to perform diversity reception efficiently without increasing the scale of the apparatus, when the total number of simultaneously connected cells has reached N cells including an HSDPA serving cell a control section104keeps a switch103connecting a buffer102-1to a despreading section105, and conversely, when the total number of simultaneously connected cells has not reached N cells including an HSDPA serving cell, after completion of despreading and delay profile generation for the simultaneously connected cells performed for the received signal of an antenna #1, control section104switches switch103to connect a buffer102-2to despreading section105. By means of this switching control, diversity reception is performed for an HSDPA serving cell only when the total number of simultaneously connected cells has not reached N and there are free resources.
