Abstract: A server electric power management apparatus 40 comprises a controller 43 configured to instruct multiple pieces of equipment 10 to use a first operation pattern for controlling the equipment 10, so as to achieve a desired operation result by mutual cooperation of the multiple pieces of equipment 10. The controller 43 changes the operation pattern used in the multiple pieces of equipment 10 from the first operation pattern to a second operation pattern, when a target equipment to be stopped is stopped. the second operation pattern is an operation pattern controlling the multiple pieces of equipment 10 other than the target equipment to be stopped to allow an operation result achieved by the mutual cooperation of the multiple pieces of equipment other than the target equipment to be stopped to approach to a desired operation result.

A server device (20) extracts at least one of an elapsed time and remaining number of control instructions not acquired by a power control device (10) by polling and provides a warning when at least one of the elapsed time and the remaining number is at least a predetermined value. When the server device does not respond to polling, the power control device (10) creates a control instruction based on control guideline information and executes the control instruction.

Abstract: A control unit (102) in a radio base station (1A) receives from a radio terminal (2A) a measured W-CQI corresponding to a local sector, and also acquires the utilization ratio of a PDCCH corresponding to the sector. Also, in addition to receiving a measured W-CQI corresponding to the local sector, the control unit (102) in the radio base station (1A) acquires from other radio base stations (1B and 1C) utilization ratios of PDCCHs and PDSCHs corresponding to other sectors. Additionally, the control unit (102) in the radio base station (1A) estimates the PDCCH quality (SINR) corresponding to the local sector on the basis of a SINR obtained from the measured W-CQIs and also on the basis of the utilization ratios of PDCCHs and PDSCHs corresponding to other sectors.

Further, the control unit (102) in the radio base station (1A) multiplies the measurement W-CQI corresponding to the serving sector by the reciprocal of the usage rate of the PDCCH corresponding to the radio base station (1A), and thereby estimates the SINR of the PDCCH corresponding to the serving sector at the radio terminal (2A).

Abstract: When allocating CCEs as a radio resource to a new radio terminal within a predetermined sector, the disclosed radio base station (1) acquires the new AL corresponding to the new radio terminal, and identifies CCEs that cannot be allocated (non-allocatable CCEs) determined in response to an AL that is larger than said new AL. Furthermore, when a new search space wherein the CCE is completely unused exists among new search spaces corresponding to the new radio terminal, and when a non-allocatable CCE is contained in said new search space wherein the CCE is completely unused, the radio base station (1) allocates said non-allocatable CCE to the new radio terminal.
