ENABLING NON-COHERENT JOINT TRANSMISSION - A simplified explanation of the abstract
This abstract first appeared for US patent application 17758105 titled 'ENABLING NON-COHERENT JOINT TRANSMISSION
Simplified Explanation
The abstract of this patent application describes a wireless communication system where a user equipment (UE) receives downlink control information that includes a precoding matrix indicator and a set of demodulation reference signal (DMRS) antenna ports. The UE then associates different sets of antenna indices of the precoding matrix with different code-division multiplexing (CDM) groups of the DMRS antenna ports and transmits an uplink transmission based on these associations.
- The patent application describes a method for efficient wireless communication using precoding matrix indicators and DMRS antenna ports.
- The UE receives downlink control information that includes information about the precoding matrix and the DMRS antenna ports.
- The UE associates different sets of antenna indices of the precoding matrix with different CDM groups of the DMRS antenna ports.
- The UE then transmits an uplink transmission based on these associations, improving the efficiency of the wireless communication system.
Potential Applications
This technology can be applied in various wireless communication systems, including cellular networks, Wi-Fi networks, and other wireless communication networks. It can improve the efficiency and reliability of uplink transmissions, leading to better overall network performance.
Problems Solved

- Reduced interference and improved reliability of transmissions.
- Enhanced overall network performance and user experience.
Original Abstract Submitted
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information that indicates a transmit precoding matrix indicator, that identifies a precoding matrix, and a set of demodulation reference signal (DMRS) antenna ports. A first association may be between a first set of antenna indices of the precoding matrix, that form a first transmission group, and a first code-division multiplexing (CDM) group of the set of DMRS antenna ports, and a second association may be between a second set of antenna indices of the precoding matrix, that form a second transmission group, and a second CDM group of the set of DMRS antenna ports. The UE may transmit an uplink transmission according to the first association and the second association. Numerous other aspects are provided.
