    • 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.
    • 公开了一种用于使无线基站能够对无线终端进行点对点用户信息通信和点对多点用户信息通信的信息通信方式。 第一媒体访问控制标识符被分配给作出连接请求的无线终端,广播第一媒体访问标识符和无线终端之间的对应关系,并且使用对应于时隙的时隙来发送去往无线终端的用户信息 到第一媒体访问控制标识符。 另一方面,向多播信息标识符分配第二媒体访问控制标识符,发送第二媒体访问控制标识符和多播信息标识符之间的对应关系,并且使用与该多播信息标识符相对应的时隙来发送多播信息 第二媒体访问控制标识符。
