Abstract: According to one embodiment of the present invention, a method of receiving a downlink signal, which is received by a user equipment in a wireless communication system, includes the steps of receiving a TxPowerResourceConfigList for a user equipment which is not configured with a transmission mode 10 and one or more zeroTxPowerResourceConfigLists and receiving a DCI (downlink control channel) including a PRI (PDSCH RE mapping indicator). In this case, the user equipment can recognize whether a PDSCH (physical downlink shared channel) is mapped to REs (resource elements) to which a CSI-RS is transmittable using the one or more zeroTxPowerResourceConfigLists and the PRI.

Abstract: The present invention relates to a method for a terminal receiving an enhanced physical downlink control channel (EPDCCH) in a wireless access system supporting an unlicensed band, and the method may comprise the steps of: receiving, through an unlicensed-band cell (Ucell) configured in an unlicensed band, an EPDCCH comprising control information for scheduling the Ucell; and, on the basis of the control information, receiving downlink data from the Ucell. Here, if the EPDCCH is transmitted through a partial subframe (pSF), enhanced resource element groups (EREGs) constituting the EPDCCH are indexed from the start symbol of the pSF, and the pSF has a smaller size than one subframe, and the starting position of the pSF may not correspond to the subframe boundary of a primary cell (Pcell) configured in a licensed band.

Abstract: The present invention relates to a wireless communication system, and more specifically, disclosed are a method and an apparatus for transmitting or receiving a downlink signal by considering an antenna port relationship. A method for user equipment receiving a physical downlink shared channel (PDSCH) signal in the wireless communication system, according to one embodiment of the present invention, comprises the steps of: determining a start symbol index of the PDSCH from a downlink subframe; and receiving the PDSCH signal based on the start symbol index, wherein the PDSCH can be scheduled by means of downlink control information (DCI) which is received through a physical downlink control channel (PDCCH) or an enhanced PDCCH (EPDCCH). When the DCI is comprised according to DCI format 1A, which is transmitted through the EPDDCH, and the downlink subframe is a non-multicast broadcast single frequency network (MBSFN) subframe, the start symbol index can be determined depending on an EPDCCH start symbol value which is established by an upper layer.
