PROBLEM TO BE SOLVED: To improve the bit rate of data transmission in a time division duplex TDD system and its flexibility. SOLUTION: A header slot 10 consists of a time slot, based on the time division duplex system. The header slot 10 consists of a downlink channel 11, through which data are transmitted from a base station 1 to mobile stations 2-4 and an uplink 12, through which the data are transmitted from the mobile stations 2-4 to the base station 1. The downlink channel 11 consists of a synchronization channel 13, a common notice channel 14 and an ancillary notice channel 15. The uplink channel 12 consists of a random access channel 16. |
