摘要： The present disclosure relates to a 5G or pre-5G communication system to be provided for supporting a higher data transfer rate beyond a 4G communication system such as LTE. According to the present disclosure, there is provided a method for supporting repetitive transmission of uplink data by a base station in a mobile communication system operating in a time division duplex (TDD) based cell including at least one subframe for uplink transmission and at least one subframe for downlink transmission comprising repeatedly transmitting uplink data scheduling information in a downlink subframe where an uplink hybrid automatic repeat request (HARQ) process is defined and repeatedly receiving uplink data in uplink subframes which start from an uplink subframe according to an HARQ transmission timing of an HARQ process defined in a downlink subframe where the repetitive transmitting of the uplink data scheduling information is complete.

摘要： The present disclosure relates to a method performed by a base station. The method comprises the following steps: transmitting, to a user equipment (UE), configuration information including information on a total number of antenna ports for channel status information reference signal (CSI-RS) and information on at least two CSI-RS resources; and transmitting, to the UE, a plurality of CSI-RSs based on the at least two CSI-RS resources and the total number of antenna ports for CSI-RS. The total number of antenna ports for CSI-RS is defined based on a product of a number of the at least two CSI-RS resources and a number of antenna ports for one CSI-RS. The information on the at least two CSI-RS resources includes a bitmap indicating frequency domain location corresponding to the at least two CSI-RS resources. Each one of the at least two CSI-RS resources is configured with same number of antenna ports for CSI-RS, and the total number of antenna ports for CSI-RS is more than or equal to eight.
