BASE STATION APPARATUS, MOBILE TERMINAL APPARATUS AND COMMUNICATION CONTROL METHOD

摘要

To provide a base station apparatus, mobile terminal apparatus and communication control method for enabling control adapted to interference inside a Heterogeneous network to be performed to support the next-generation mobile communication system, a base station apparatus (20) shares at least a part of the frequency band with another base station apparatus (40) that covers a macro-cell, covers a pico-cell (C1), is capable of transmitting a downlink transmission frame at transmission timing different from the another base station apparatus (40), and is configured to set resources, in which the downlink transmission frame undergoes interference from another downlink transmission frame including a blank period transmitted from the another base station apparatus (40), as blank resources, and assign user data to the downlink transmission frame while avoiding the blank resources.

主权项

1. A base station apparatus which shares at least a part of a frequency band with another base station apparatus that covers a large-scale cell, covers a small-scale cell, and is capable of transmitting a downlink transmission frame at transmission timing different from the another base station apparatus, comprising:
a blank resource setting section configured to set resources, in which the downlink transmission frame undergoes interference from another downlink transmission frame including a blank period transmitted from the another base station apparatus, as blank resources; a user data assigning section configured to assign user data to the downlink transmission frame while avoiding the blank resources; and a transmission section configured to transmit the downlink transmission frame assigned the user data to a mobile terminal apparatus.
