METHOD FOR TRANSMITTING REFERENCE SIGNALS FOR RELAY NODE

摘要

A method for transmitting reference signals for a relay node is disclosed. The method includes transmitting a first reference signals for a base station in a first transmission region of a subframe and a second reference signals for a relay node in a second transmission region of the subframe. The first transmission region and the second transmission region in the subframe are regions for transmitting data and the first transmission region and the second transmission regions are different sub-bands of Physical Downlink Shared Channel (PDSCH). Accordingly, it is possible to transmit wideband reference signals by the relay node, to maximally support a Long Term Evolution (LTE) user equipment while operating the relay node, and to perform cooperative multipoint transmission and reception between the base station and the relay node.
