Abstract

Official abstract text for this publication.

A centralized-control base station connected to a first transceiving unit and a second transceiving unit includes a first signal quality obtaining unit configured to obtain both uplink signal quality from a mobile station to the first transceiving unit and downlink signal quality from the first transceiving unit to the mobile station; a second signal quality obtaining unit configured to obtain both uplink signal quality from the mobile station to the second transceiving unit and downlink signal quality from the second transceiving unit to the mobile station; and a control unit configured to allow downlink data to be transmitted from the first transceiving unit, downlink feedback information to be received by the second transceiving unit, uplink data to be received by the second transceiving unit, and uplink feedback information to be transmitted from the first transceiving unit, when the downlink signal quality from the first transceiving unit to the mobile station is better than the downlink signal quality from the second transceiving unit to the mobile station and the uplink signal quality from the mobile station to the second transceiving unit is better than the uplink signal quality from the mobile station to the first transceiving unit.
