Title:
METHOD AND APPARATUS FOR CONFIGURING DEMODULATION REFERENCE SIGNAL INFORMATION IN WIRELESS CELLULAR COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/125090
Kind Code:
A1
Abstract:
The present disclosure relates to a communication method and system for converging a 5th generation (5G) communication system with a technology for Internet of Things (IoT) to support higher data rates beyond a 4th generation (4G) system. The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart homes, smart buildings, smart cities, smart or connected cars, health care, digital education, smart retail, and security and safety services. The present invention proposes a method and apparatus for effectively configuring DMRS-related information. A method of a UE is provided. The method includes receiving, from a base station, configuration information including first information on a number of an additional demodulation reference signal (DMRS) symbol by higher layer signaling, receiving, from the base station, downlink control information (DCI) including second information on a time domain resource, identifying third information on a duration in symbols of a scheduled physical downlink shared channel (PDSCH) resource based on the second information, identifying a position of a DMRS symbol based on the first information and the third information, and receiving, from the base station, at least one DMRS based on the position of the DMRS symbol.
