ABSTRACT:
A base station transmits downlink signals to mobile terminals of users A to C with respective transmission power corresponding to downlink quality. A downlink quality estimating section (106) uses the transmission power from a transmission power control section to compare transmission power between the users, and estimates that a terminal with low transmission power has high downlink quality. The priorities are determined so that the priority is increased as the transmission power is lower. Thus determined priority information is output to a scheduling section (107). The scheduling section (107) performs scheduling based on the priority information. The section (107) assigns DSCH to terminals in ascending order of transmission power. User A is first assigned DSCH, user B is second assigned DSCH, and user C is third assigned DSCH. It is thus possible to perform scheduling and MCS selection of DSCH with the need of information from a terminal eliminated.
