Abstract
A method is provided for receiving a downlink signal at a downlink reception entity in a wireless communication system. Downlink control information is received 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). Downlink data is received by demodulating a Physical Downlink Shared Channel (PDSCH) in one or more second RB pairs scheduled by the downlink control information within the RB bundle by using a second DMRS based on an assumption that a same precoder is applied to the scheduled one or more second RB pairs.
