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.

Abstract: A method of decoding a backhaul downlink signal is presented. A relay node (RN) receives a higher layer signal indicating a maximum transmission rank from a base station (BS), receives control information containing a resource allocation for downlink data through a relay control channel from the BS, demodulates the control information, and receives the downlink data through a data channel based on the control information. The control information is mapped to resource elements (REs) which do not overlap with user equipment-specific reference signal (URS) REs in a control region which is used for the relay control channel transmission of the BS. The URS REs are reserved REs for URSs according to the maximum transmission rank.
