Abstract:
1. A method for receiving a downlink signal by a user equipment (UE) from a base station, the method comprising: receiving downlink control information (DCI) through a downlink control channel, wherein the DCI includes resource assignment information for downlink data, and wherein the DCI includes a new data indicator (NDI) for each of a first transport block and a second transport block; and receiving the downlink data through a downlink data channel based on the resource assignment information, the downlink data including at least the first transport block or the second transport block, wherein, if the first transport block or the second transport block is disabled, one antenna port among a first antenna port and a second antenna port is used for single-antenna port transmission of an enabled transport block, wherein a 1-bit NDI of the disabled transport block included in the DCI indicates the one antenna port used for the single-antenna port transmission of the enabled transport block, wherein the DCI does not use a TB-to-codeword flag, and wherein another antenna port among the first antenna port and the second antenna port is allowed to be associated with transmission of downlink data to another UE.
