UPLINK CODEBOOK DESIGN - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240340887 titled 'UPLINK CODEBOOK DESIGN
The patent application describes apparatuses and methods for uplink codebook design, specifically focusing on the transmission of a physical uplink shared channel (PUSCH) based on a transmit precoding matrix indicator (TPMI) from an uplink codebook.
- Method involves receiving a configuration for an uplink codebook for 8 antenna ports partitioned into groups and an indication of a TPMI for PUSCH transmission.
- The TPMI indicates a precoding matrix from the codebook, based on up to k submatrices, each being a full-coherent precoding matrix.
- The UE transmits PUSCH based on the indicated TPMI, optimizing the precoding matrix for transmission efficiency.
Potential Applications: - 5G and beyond wireless communication systems - Mobile networks and base stations - IoT devices requiring efficient uplink transmission
Problems Solved: - Optimizing uplink codebook design for efficient PUSCH transmission - Enhancing spectral efficiency in wireless communication systems
Benefits: - Improved uplink transmission performance - Enhanced system capacity and reliability - Better utilization of antenna resources
Commercial Applications: Title: Enhanced Uplink Transmission for 5G Networks This technology can be utilized in: - Telecom equipment manufacturing - Wireless network infrastructure development - IoT device communication systems
Questions about Uplink Codebook Design: 1. How does the method optimize precoding matrices for uplink transmission? - The method selects the most suitable precoding matrix from the codebook based on the TPMI indication, ensuring efficient PUSCH transmission. 2. What impact does efficient uplink codebook design have on overall network performance? - Efficient design leads to improved spectral efficiency, enhanced system capacity, and better resource utilization in wireless communication systems.
Original Abstract Submitted
apparatuses and methods for uplink (ul) codebook design are provided. a method performed by a user equipment (ue) is provided. the method includes receiving a configuration about an uplink (ul) codebook (c) for n=8 antenna ports partitioned into ngroups; receiving an indication indicating a transmit precoding matrix indicator (tpmi) for transmission of a physical uplink shared channel (pusch); and transmitting the pusch based on the indicated tpmi. the tpmi indicates a precoding matrix (w) from the ul codebook (c) and the precoding matrix (w) is based on up to k submatrices. each of the k submatrices is a full-coherent (fc) precoding matrix for
