COMMUNICATION CONTROL METHOD, COMMUNICATION SYSTEM, AND BASE STATION APPARATUS

摘要

PROBLEM TO BE SOLVED: To carry out interference reduction control in a heterogeneous network without imposing burdens to a user terminal.

SOLUTION: In a communication control method in a heterogeneous network, a second kind of cell (HeNB) detects uplink interference from a first user terminal (MUE) connected to a first kind of cell (MeNB). The second kind of cell (HeNB) notifies the first kind of cell (MeNB) of an interference pattern of the detected interference. The first kind of cell (MeNB) specifies the first user terminal (MUE) that is an interference source based on the interference pattern. The first kind of cell (MeNB) notifies the second kind of cell (HeNB) of scheduling information for the specified first user terminal (MUE). The second kind of cell (HeNB) carries out scheduling for a second user terminal (HeUE) connected with the second kind of cell (HeNB), based on the scheduling information for the first user terminal (MUE).
