摘要 |
<p>In a mobile communication system and a WLL communication system sharing a frequency or a time slot including time-divided CDMA method and TDMA method, radio waves are divided into groups according to a magnitude of a transmitting power and each group is assigned to a different time slot. Further, a frame synchronization is established among the base stations based on the transmitted radio waves, and cellular communication systems and PCS systems each having different time slot length are performed under a same frame synchronization. <IMAGE></p> |
