Abstract: The present invention relates to a wireless communication system, and more specifically, to a method and an apparatus for transmitting or receiving a downlink signal considering an antenna port relationship. The method for enabling a terminal to receive a physical downlink sharing channel (PDSCH) signal in the wireless communication system according to one embodiment of the present invention can determine a PDSCH start symbol index according to the predetermined priority and receive the PDSCH signal therethrough. The PDSCH start symbol index can be determined when a PDSCH start symbol value included in a PDSCH resource element mapping and Quasi co-location Indicator (PQI) parameter set is determined by an upper layer. The PDSCH start symbol index can be determined according to the PDSCH start symbol value for a cell receiving the PDSCH when the PDSCH start symbol value included in the PQI parameter set is not determined by the upper layer.

Abstract: A method for a relay to receive downlink control information from a base station through a Relay-Physical Downlink Control Channel (R-PDCCH), and the relay therefore are discussed. The method according to one embodiment includes determining one or more candidate positions for the R-PDCCH; monitoring whether or not the R-PDCCH is being transmitted at the one or more candidate positions; and receiving, through the monitoring that the R-PDCCH is being transmitted, the downlink control information included in the R-PDCCH. The one or more candidate positions are set as a Virtual Resource Block (VRB) set including N VRBs, and a combination of 2 adjacent candidate positions among candidate positions of a lower aggregation level composes one of candidate positions of a higher aggregation level. The VRBs of the VRB set are assigned numbers. Respective candidate positions for the R-PDCCHs of aggregation levels L are determined as VRBs.
