Resource allocation method for shared base station
First Claim
1. A communication apparatus comprising:
- calculation circuitry that calculates, using a function that uses a first frequency bandwidth amount or a first number of terminals as a variable, a second frequency bandwidth amount corresponding to an extreme value in the function of an operator to which the communication apparatus belongs or a second number of terminals corresponding to the an extreme value in the function of the operator, the first frequency bandwidth amount being a frequency bandwidth amount allocated from among a frequency bandwidth amount held by the operator to a terminal belonging to another operator, the first number of terminals being a number of terminals connected to a picocell belonging to the other operator among terminals belonging to the operator of the communication apparatus;
a transmitter that transmits the second frequency bandwidth amount or the second number of terminals to a management apparatus and that receives, from the management apparatus, a minimum value of a plurality of the second frequency bandwidth amounts or a minimum value of a plurality of the second numbers of terminals calculated in each of a plurality of operators; and
allocation circuitry that allocates a resource to a signal of the terminal belonging to the operator and the terminal belonging to the other operator based on the minimum value of the plurality of second frequency bandwidth amounts or the minimum value of the plurality of the second numbers of terminals.

Abstract
In this device: a gain calculator (101) uses a function in which the variable is a first resource amount from among the resource amounts possessed by an operator in question, and calculates a second resource amount at which the maximum gain is reached in the function of the operator to which the device in question belongs, the first resource amount being a resource amount allocated to a terminal belonging to another operator; a transmitter/receiver (102) transmits the second resource amount to the manager (300), and receives, from the manager (300), the minimum value among second resource amounts calculated in each of the operators; and the allocation unit (103) allocates resources to the signal of the terminal belonging to the operator in question and to the terminal belonging to the other operator on the basis of the minimum value among the second resource amounts calculated by each of the operators.

8. A macro cell base station apparatus in a communication system that includes a plurality of macro cell base station apparatuses and a management apparatus, the macro cell base station apparatus comprising:
-
calculation circuitry that calculates, using a function that uses a first frequency bandwidth amount as a variable, a second frequency bandwidth amount corresponding to a an extreme value in the function of an operator to which the macro cell base station apparatus belongs, the first frequency bandwidth amount being a frequency bandwidth amount allocated from among a frequency bandwidth amount held by the operator to a terminal belonging to another operator; a transmitter that transmits the second frequency bandwidth amount to the management apparatus and that receives, from the management apparatus, a minimum value of a plurality of the second frequency bandwidth amounts calculated in each of a plurality of operators to which the macro cell base station apparatuses respectively belong; and allocation circuitry that allocates the received minimum value of a plurality of the second frequency bandwidth amounts to the terminal belonging to the other operator and allocates a remaining frequency bandwidth amount to the terminal belonging to the operator, the remaining frequency bandwidth amount being calculated by subtracting the received minimum value of a plurality of the second frequency bandwidth amounts from a frequency bandwidth amount held by the operator. - View Dependent Claims (9, 10, 11, 12, 13)
