Claim:
1. A method for receiving a downlink signal at a downlink reception entity in a wireless communication system, the method comprising: receiving downlink control information by demodulating a Physical Downlink Control Channel (PDCCH) in a first resource block (RB) pair within an RB bundle by using a first Demodulation Reference Signal (DMRS) in the first RB pair; and receiving downlink data by demodulating a Physical Downlink Shared Channel (PDSCH) in one or more second RB pairs within the RB bundle based on channel estimation performed using a second DMRS in the one or more second RB pairs, wherein the second DMRS is used for the channel estimation based on an assumption that a same precoder is applied to the one or more second RB pairs within the RB bundle except the first RB pair.
