RADIO COMMUNICATION SYSTEM, INFORMATION PROVIDING DEVICE, MOBILE TERMINAL, AND METHOD FOR PROVIDING INFORMATION TO MOBILE TERMINAL
First Claim
1. A radio communication system that provides information to a mobile terminal via a base station that performs radio communication with the mobile terminal, whereinthe base station is capable of performing point-to-point radio communication with the mobile terminal, and capable of performing point-to-multipoint radio communication with the mobile communication terminal,the mobile terminal is capable of receiving first downlink information that has been transmitted from the base station by point-to-multipoint radio communication receivable by a plurality of the mobile terminals, and capable of receiving second downlink information that has been transmitted from the base station by point-to-point communication,the mobile terminal is capable of transmitting uplink information to the base station by point-to-point radio communication, andthe first downlink information and the second downlink information are formed such that information to be used in the mobile terminal is obtained when the mobile terminal performs information processing by using both the first downlink information and the second downlink information that received from the base station.

Abstract
Downlink is achieved by point-to-multipoint communication. There is provided a radio communication system 1 that provides information to a mobile terminal 3 via a radio communication device 2 that performs radio communication with the mobile terminal 3. The mobile terminal 3 is capable of receiving first downlink information that has been transmitted by point-to-multipoint radio communication receivable by a plurality of the mobile terminals 3, and capable of receiving second downlink information that has been transmitted by point-to-point communication. The mobile terminal 3 is capable of transmitting uplink information by point-to-point radio communication. The first downlink information and the second downlink information are formed such that information to be used in the mobile terminal 3 is obtained when the mobile terminal 3 performs information processing by using both the first downlink information and the second downlink information.
