Title:
DEMODULATION REFERENCE SIGNAL CONFIGURATION AND INDICATION SCHEMES
Document Type and Number:
WIPO Patent Application WO/2023/159535
Kind Code:
A1
Abstract:
A method of wireless communication is described. The wireless communication method includes receiving, by a communication device, an antenna port indication; and determining, by the communication device, a first demodulation reference signal (DMRS) port based on the antenna port indication. The first DMRS port is mapped to two resource elements of one physical resource block on one OFDM (Orthogonal Frequency Division Multiplexing) symbol.
