Abstract
A radio communication device which manages a network defines a predetermined transmission frame cycle, allocates in the frame specific access slots as timing with which the individual radio communication devices in the network concerned receive a transmission, puts the information of the allocation in a beacon signal, and transmits the signal. Each radio communication device performs receiving operation at access slots specific to the device itself defined by the beacon signal. When information transmission is made between arbitrary communication devices in the network, access slots for the device which is to receive the information are used.
