RADIO COMMUNICATION BASE STATION DEVICE, RADIO COMMUNICATION RELAY STATION DEVICE, RADIO COMMUNICATION TERMINAL DEVICE, RADIO COMMUNICATION SYSTEM, AND RADIO COMMUNICATION METHOD

摘要

It is possible to provide a radio communication base station device, a radio communication relay station device, a radio communication terminal device, a radio communication system, and a radio communication method which can minimize a delay and effectively use resources. When a terminal starts an uplink communication with a base station via a repeater, [ST403] a base station transmits to a repeater, Grant 1 for the base station to allocate an initial transmission resource to the terminal and Multi-direction Grant which can be applied either to retransmission from the terminal to the repeater or the relay from the repeater to the base station, and [ST404] the Grant 1 and the Multi-direction Grant are relayed to the terminal.
