IPC: H04W56/00
Filed: 1998-11-17
Abstract: PROBLEM TO BE SOLVED: To prevent the mutual interference of a related reference system, to be operated at a comparatively high power level concerning a method for controlling operation of transmission/reception in local radio communication system, which has a main unit and at least one slave unit and operates at a low power level. SOLUTION: A time base for communication with a slave unit SU is specified as the function of the time base of a reference system 12 at a main unit MU, and a frame length specified based on that time base is reported to each SU. Thus, the time base required for specifying each frame time can be changed corresponding to respective required conditions. As a result, when this local radio communication system 10 is used together with the reference system such as a cellular mobile radio system, the overlapping of communication operation can be prevented easily.
