Patent ID: 8295232

Claim:
A base station, comprising: a scheduling unit configured to use, for a particular radio bearer, any one of a persistent scheduling in which a transmission opportunity is assigned to data addressed to a mobile station per a predetermined period, and a non-persistent scheduling in which a transmission opportunity is assigned to data addressed to the mobile station having a favorable reception condition; a control information generating unit configured to generate control information to be used in the persistent scheduling; a control information notifying unit configured to notify, to the mobile station, the control information; and a switching notifying unit configured to notify, to the mobile station, that a scheduling to be used for the particular radio bearer should be switched from the non-persistent scheduling to the persistent scheduling, wherein the scheduling unit is configured to switch the scheduling to be used for the particular radio bearer, from the non-persistent scheduling to the persistent scheduling, based on a reception condition of the control information in the mobile station, wherein the scheduling unit is configured to switch the scheduling to be used for the particular radio bearer, from the non-persistent scheduling to the persistent scheduling, when a reception quality in the particular radio bearer is determined as equal to or less than a predetermined threshold, based on a measurement signal transmitted from the mobile station and indicating a propagation path condition: wherein the scheduling unit is configured to transmit downlink data via a shared channel based on the persistent scheduling when it is determined that the scheduling to be used should be switched from the non-persistent scheduling to the persistent scheduling, and wherein the scheduling unit is configured to transmit the downlink data via the shared channel for the non-persistent scheduling based on a normal scheduling when it is determined that the scheduling to be used should not be switched from the non-persistent scheduling to the persistent scheduling.
