    Publication number: 20160360512
    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) in the first RB pair. Further, downlink data is received by demodulating a Physical Downlink Shared Channel (PDSCH) in one or more second RB pairs within the RB bundle by using a second DMRS in the one or more second RB pairs. The second DMRS is used based on an assumption that a same precoder is applied to the one or more second RB pairs.
