RELAY TRANSMISSION SYSTEM, BASE STATION, RELAY STATION, AND METHOD

摘要

A base station used in a relay transmission system is disclosed. The base station includes a metric provision unit providing a metric indicating radio propagation conditions of a user equipment terminal; a relay information generation unit generating a relay information for the user equipment terminal based on the metric, the relay information indicating whether an uplink signal is to be transmitted via one or more relay stations; a scheduling unit generating an allocation plan of radio resources based on the relay information; and a control signal transmission unit transmitting a control signal including a scheduling information indicating the allocation plan.
