DEMODULATION REFERENCE SIGNAL (DM-RS) DESIGN FOR RATE-SPLITTING MULTI-USER MULTIPLE INPUT MULTIPLE OUTPUT (MU-MIMO) COMMUNICATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 17940355 titled 'DEMODULATION REFERENCE SIGNAL (DM-RS) DESIGN FOR RATE-SPLITTING MULTI-USER MULTIPLE INPUT MULTIPLE OUTPUT (MU-MIMO) COMMUNICATION

Simplified Explanation

The method described in the patent application involves wireless communication at a user equipment (UE) using a rate-splitting multiple access scheme for downlink transmissions. The UE receives downlink control information (DCI) from a network entity, which includes information about a common stream, a private stream, and demodulation reference signals (DM-RS) for both streams. Based on the DCI, the UE determines the configuration for the DM-RS for the common stream and the private stream, and then receives the downlink transmission accordingly.

• Wireless communication method at a user equipment (UE)
• Uses rate-splitting multiple access scheme for downlink transmissions
• Receives downlink control information (DCI) from a network entity

Original Abstract Submitted

Disclosed is a method of wireless communication. The method is performed at a user equipment (UE). The method comprises receiving, from a network entity, downlink control information (DCI) for a downlink transmission, wherein the downlink transmission is based on a rate-splitting multiple access scheme, and wherein the downlink transmission comprises a common stream, a demodulation reference signal (DM-RS) for the common stream, a private stream and a DM-RS for the private stream, determining, based on the DCI, a DM-RS configuration for the DM-RS for the common stream and for the DM-RS for the private stream, and receiving, based on the DM-RS configuration, the downlink transmission.
