Title:
DMRS PORT GROUPING METHOD AND APPARATUS FOR USE IN WIRELESS CELLULAR COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/039917
Kind Code:
A1
Abstract:
The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method of a terminal in a wireless communication system is provided. The method includes identifying demodulation reference signal (DMRS) type information and DMRS symbol length information, identifying port number information for receiving a DMRS and receiving the DMRS based on the DMRS type information, the DMRS symbol length information and port number information, wherein the port number information indicates a port number for the terminal in DMRS information including parameters for code division multiplexing (CDM) group information, offset information, frequency-domain orthogonal cover code (OCC) information, and time-domain OCC information corresponding respectively to multiple port numbers, and wherein the DMRS information is defined per DMRS type.
