Transmission of data indicating dynamic transmission/reception periods

摘要

A mobile communication fixed station 101 transmits significant data to a mobile station 103 (104) after holding the significant data for a predetermined time, and no significant data are transmitted to the mobile station during that time. When there are no significant data which are being held, the fixed station 101 transmits remaining time data indicative of the predetermined time to the mobile station, and no significant data are transmitted to the mobile station. When significant data is being held, time data indicative of the remaining time until the start of transmission of the significant data is transmitted to the mobile station in each slot from the time significant data occurs until the time the significant data is transmitted. The fixed station 103 , which has received the remaining time data stops receiving for a time interval corresponding to the remaining time.
