摘要

Disclosed is a radio communication system in which transmission parameters, such as MCS of MBSFN, the number of subframes, and a transmission power of a reserved cell, are adaptively output, based on a unicast traffic volume in a MBSFN area, a number of terminals, and a number of cells of the MBSFN area, so that a system throughput in the MBSFN area is maximized while satisfying an MBSFN quality requirement condition.

主权项

1. A wireless communication system including a function of MBSFN (Multimedia Broadcast Multicast Service Single Frequency Network), comprising:
a MCE (multi-cell/multicast coordination entity) comprising:
a control unit to send control information relating to the MBSFN to a radio station, the control information including a cell type relating to the MBSFN in a cell of the radio station and radio resource information of the MBSFN, the radio station comprising:
a transmission unit to send at least a part of the control information, except the cell type, to a mobile station,wherein the part of the control information sent to the mobile station includes at least a part of the radio resource information of the MBSFN,wherein the cell type represents that the cell is a MBSFN service cell to contribute to the MBSFN or a reserved cell not to contribute to the MBSFN, andwherein the radio station in the reserved cell performs unicast transmission with a reduced transmission power, does not perform unicast transmission at all, or performs single-cell/multicast transmission, during a MBSFN subframe time period.
