Abstract: A method of transmitting a device-to-device (D2D) signal by a first D2D user equipment (UE) supporting D2D communication. A first D2D UE requests a second D2D UE to repeatedly broadcast or multicast the D2D data together with the first D2D UE on a same time-frequency resource based on a single frequency network (SFN) scheme. In addition, scheduling assignment information includes information for restricting the second D2D UE from broadcasting or multicasting the D2D data received from the first D2D UE according to the request of the first D2D UE based on the SFN scheme when a distance from the first D2D UE is equal to or greater than a preset distance.

Abstract: Provided are a method and an apparatus for receiving a downlink signal in a wireless communication system. The method includes receiving resource block assignment information including a bitmap and receiving the downlink signal through a resource block group (RBG) indicated by the bitmap in a bandwidth part. A total number of resource block groups (RBGs) in the bandwidth part is determined based on an index of a start resource block of the bandwidth part, a size of the bandwidth part, and a size of one resource block group.

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.
