MOBILE COMMUNICATION SYSTEM, TERMINAL, BASE STATION DEVICE, AND DATA COMMUNICATION METHOD

摘要

A base station transmits Multimedia Broadcast Service data on a resource block allocated to the Multimedia Broadcast Service to a plurality of terminals. The terminals take out the Multimedia Broadcast Service data from the resource block allocated to the Multimedia Broadcast Service, which is included in the received signal from the base station and measures the reception quality of the resource block. If the reception quality thereof drops in any terminal, the base station transmits auxiliary data on another resource block. The terminal in which the reception quality has dropped takes out the auxiliary data included in the received signal and generates it into the Multimedia Broadcast Service data.
