摘要:
A power management system comprises a plurality of HEMSs 10 and a CEMS 40. The CEMS 40 transmits, to a power company 60, configuration information of the plurality of consumers 70 managed by the CEMS 40. The power curtailment signal (DR; Demand Response) transmitted from the power company 60 to the CEMS 40 is determined in accordance with the configuration information. The upper power management apparatus transmits, to each HEMS 10, reduction information including an amount of power that should be reduced in each consumer 70 in response to a power curtailment signal transmitted from the power company 60 after transmitting the configuration information.

A power management system comprises a plurality of HEMSs 10 and CEMSs 40. The CEMS 40 receives, from each HEMS 10, power information including the amount of power consumed by a load connected to each HEMS 10. The CEMS 40 transmits, to each HEMS 10, reduction information including the amount of power that should be reduced in each consumer, in response to a curtailment signal and the power information.

Disclosed is a large cell base station (100) that, in cases in which the interference from small cell base stations (300) experienced by a radio terminal (200) connected to said large cell base station (100) is at or above a prescribed value, estimates a non-interference PF evaluation value for assessing whether or not the allocation of resource blocks to the radio terminal (200) is suitable when said interference is assumed to not be present. Additionally, the large cell base station (100) transmits band-use restriction information, which indicates use restrictions for the frequency bands corresponding to the resource blocks, to the small cell base stations (300) in cases in which the non-interference PF evaluation value is at or above a prescribed value.

A threshold calculation apparatus (200) corrects each of ideal E-SINR thresholds in an MCS threshold table in accordance with a reduction in accuracy of the E-SINR due to the use of a first transformation table and a second transformation table, and generates a corrected MCS threshold table. In the case where a wireless base station obtains an E-SINR from a plurality of SINRs using the first transformation table and the second transformation table, the wireless base station determines an MCS corresponding to the E-SINR also based on the corrected MCS threshold table.

A radio base station (1) includes a scheduler (114) and a control unit (112). As a reception device has a higher reception quality, the scheduler (114) sets a higher allocation priority of a radio resource used for data transmission. When the priority β set for a transmission destination reception device by the scheduler (114) is higher than the priority α set for transmission destination reception device, the controller (112) allocates the radio resource to both of the transmission destination reception device and the transmission destination reception device ant transmits both of the transmission data and the retransmission data by using the allocated radio resource.

A radio base station (eNB10-1) transmits a Resource Status Update message including first load information indicating the load level thereof to a radio base station (eNB10-2) when the load level thereof is less than a first threshold, and omits the transmission of the Resource Status Update message including the first load information when the load level thereof is the first threshold or more.

A radio base station (eNB1), which is used in a radio communication system that can autonomously adjust, based on load information transmitted/received between radio base stations, the radio base station parameters used for defining coverage, comprises: a network communication unit (140) that can receive, from another radio base station, first load information indicating the load level of the other radio base station and that can transmit, to the other radio base station, a request for transmission of second load information the information amount of which is greater than that of the first load information; and a control unit (120) that, when the load level of the other radio base station indicated by the received first load information satisfies a given condition, controls such that the request for transmission of the second load information is transmitted to the other radio base station.

Provided is a radio communication method employed in a base station having plural antenna elements. The method includes the steps of: setting an inner zone and an outer zone by dividing a cell formed by the base station into two; determining whether a mobile station is located in the inner zone or the outer zone on the basis of a predetermined criterion; notifying the mobile station located in the inner zone of control information, including information on channel allocation and a communication method, through a broadcast channel; and notifying the mobile station located in the outer zone of control information through a dedicated channel by beamforming using the plural antenna elements.
