Title:
METHOD AND DEVICE FOR TRANSMITTING DATA IN MOBILE COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/230869
Kind Code:
A1
Abstract:
The present disclosure relates to a communication technique for convergence of a 5G communication system for supporting a higher data transmission rate beyond a 4G system with an IoT technology, and a system therefor. The present disclosure may be applied to an intelligent service (for example, smart home, smart building, smart city, smart car or connected car, health care, digital education, retail business, security and safety-related service, etc.) on the basis of a 5G communication technology and an IoT-related technology. The present invention relates to a method of a wireless communication system, the method comprising the steps of: receiving at least one piece of quasi co-location (QCL) configuration information including information indicating a plurality of CSI-RS resources from a base station; receiving downlink control information (DCI) including an indicator indicating one of the at least one piece of QCL configuration information; estimating channel state information on the basis of at least one CSI-RS resource among the plurality of CSI-RS resources; and receiving downlink data on the basis of the channel state information, wherein the plurality of CSI-RS resources include at least one among a periodic CSI-RS resource, a semi-persistent CSI-RS resource, and an aperiodic CSI-RS resource.
