TLDR
In this article, a radio base station includes a measurement unit which measures a resource use amount in each time frame within a predetermined period; a downlink persistent allocation signal transmission unit which transmits to a mobile station, a persistent assignment signal indicating a down-link radio resource allocation start moment; and downlink communication unit which transmit downlink data using downlink radio resources starting at the downlink Radio Resource Allocation start moment.Abstract:
A radio base station includes: a measurement unit which measures a resource use amount in each time frame within predetermined period; a downlink persistent allocation signal transmission unit which transmits to a mobile station, a persistent allocation signal indicating a downlink radio resource allocation start moment; and a downlink communication unit which transmit downlink data using downlink radio resource starting at the downlink radio resource allocation start moment. The downlink persistent allocation signal transmission unit decides the downlink radio resource allocation start moment in accordance with a resource use amount in each time frame.read more
