PRECODING MATRIX INDICATION FOR PHYSICAL UPLINK SHARED CHANNEL REPETITIONS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18041654 titled 'PRECODING MATRIX INDICATION FOR PHYSICAL UPLINK SHARED CHANNEL REPETITIONS
Simplified Explanation
The patent application relates to wireless communication and specifically to the transmission of data over a physical uplink shared channel (PUSCH). The application describes a method for a user equipment (UE) to receive a downlink control information (DCI) message that includes information about transmit precoder matrix indicators (TPMI) and the quantity of transmission layers. The UE then determines precoding matrices for transmitting sets of repetitions of the PUSCH transmission based on the TPMI indices and the quantity of transmission layers.
- The patent application describes a method for a UE to receive a DCI message that includes TPMI indices and the quantity of transmission layers.
- The UE uses this information to determine precoding matrices for transmitting sets of repetitions of the PUSCH transmission.
- The method allows for efficient and optimized transmission of data over the PUSCH channel.
Potential Applications
This technology can be applied in various wireless communication systems, including cellular networks and wireless broadband systems. It can be used to improve the efficiency and reliability of data transmission over the PUSCH channel.
Problems Solved
The technology solves the problem of inefficient and suboptimal transmission of data over the PUSCH channel. By determining precoding matrices based on TPMI indices and the quantity of transmission layers, the method ensures that the data is transmitted in an optimized manner, improving overall system performance.
Benefits
The benefits of this technology include:
- Improved efficiency and reliability of data transmission over the PUSCH channel.
- Optimized transmission based on TPMI indices and the quantity of transmission layers.
- Enhanced system performance and capacity in wireless communication systems.
Original Abstract Submitted
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a downlink control information (DCI) message that includes a first field indicating a first transmit precoder matrix indicator (TPMI) index and a quantity of transmission layers and a second field indicating a second TPMI index. The UE may determine a first precoding matrix for transmitting a first set of repetitions of a physical uplink shared channel (PUSCH) transmission based at least in part on the first TPMI index and the quantity of transmission layers, and a second precoding matrix for transmitting a second set of repetitions of the PUSCH transmission based at least in part on the second TPMI index and the quantity of transmission layers. Numerous other aspects are provided.
