A radio communication apparatus that enables synchronization to be maintained reliably on a receiving side. In this apparatus, a UW detector (106) detects a UW included in a time division multiplexed mobile station received signal. A timing discrimination section (107) finds a timing difference between the UW detection timing and preset reference reception timing, and creates delay information from the found timing difference. A slot counter (109) overflows every slot and outputs an overflow signal reporting the next slot. Before a mobile station starts communication, a mobile station timing register (110) outputs at predetermined timing initial delay information obtained from a higher-level station, and after a mobile station starts communication, outputs at predetermined timing delay information input from the timing discrimination section (107).
