Radio base station apparatus, radio relay station apparatus, and resource allocation method

摘要

To provide a radio base station apparatus, a radio relay station apparatus and a resource allocation method each which perform resource division of a backhaul sub-frame more optimally and can improve a throughput of a system, in the case of relay transmission. The radio base station apparatus according to the present invention includes: a frequency bandwidth control section configured to control a frequency bandwidth in a backhaul sub-frame, based on the number of the backhaul sub-frames, the number of mobile terminal devices, and frequency utilization efficiency of a radio link; and a transmitting section configured to transmit the backhaul sub-frame with the frequency bandwidth controlled by the frequency bandwidth control section.

主权项

1. A radio base station apparatus comprising:
a frequency bandwidth control section configured to control a ratio of an amount of resource blocks to be allocated to a radio relay station apparatus to an amount of all resource blocks allocatable to the radio relay station apparatus and mobile terminal devices under a command of the radio base station apparatus in a backhaul sub-frame, based on a number of the backhaul sub-frames, a number of mobile terminal devices, and frequency utilization efficiency of a link from the radio base station apparatus to the radio relay station apparatus; and a transmitting section configured to transmit a signal for the radio relay station apparatus by using the backhaul sub-frame based on the ratio controlled by the frequency bandwidth control section.
