<p><P>PROBLEM TO BE SOLVED: To improve receiving performance by applying frequency hopping suitably even to a communication format in which a hopping minimum unit number in one transmission unit is small according to various conditions. <P>SOLUTION: When frequency hopping is performed with a communication format where transmission is performed in units of subframes having a first slot and a second slot, frequency hopping (Intra-FH) in a subframe is not applied in initial transmission according to a resending frequency, and transmission data of two slots are mapped to the same frequency band. Then frequency hopping (Inter/Intra-FH) where frequency hopping in a subframe and frequency hopping between subframes are combined to each other is applied to only resent symbols during resending (after first resending), and the transmission data are mapped to different frequency bands by the slots. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
