Abstract
Abstract An information communication scheme for enabling the radio base station to carry out both point-to-point user information communications and point-to-multipoint user information communications with respect to radio terminals is disclosed. A first media access control identifier is allocated to a radio terminal which made a connection request, a correspondence between the first media access identifier and the radio terminal is broadcast, and a user information destined to the radio terminal is transmitted using a time-slot corresponding to the first media access control identifier. On the other hand, a second media access control identifier is allocated to a multicast information identifier, a correspondence between the second media access control identifier and the multicast information identifier is transmitted, and the multicast information is transmitted using a time-slot corresonding to the second media access control identifier.
