Signal transmission method and apparatus in a relay communication system
First Claim
1. A signal transmission method by a base station to a relay node in a relay communication system, the method comprising:
- transmitting a downlink signal to the relay node via a signal transmission period of a downlink subframe,wherein an end symbol of the signal transmission period is determined according to whether downlink subframe boundary of the base station and downlink subframe boundary of the relay node are time aligned.

Abstract
The present invention relates to a data transmission/receiving method and apparatus in a relay communication system. In particular, the data transmission/receiving method through a backhaul link between a base station and a relay node in a relay communication system comprises: composing a backhaul subframe including a control signal transmission period to which a control signal is allocated and a backhaul signal transmission period to which a backhaul signal is allocated and then allocating the backhaul signal; transmitting configuration information about the backhaul subframe, the information containing symbol position or size data of the backhaul signal transmission period, to the relay node through an upper layer signal; and transmitting the backhaul signal having been allocated through the backhaul subframe to the relay node.
