METHODS AND APPARATUSES FOR CODEBOOK-BASED UPLINK TRANSMISSION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18433602 titled 'METHODS AND APPARATUSES FOR CODEBOOK-BASED UPLINK TRANSMISSION

Abstract: Example embodiments of the present disclosure relate to methods and apparatuses for codebook-based uplink transmission. A first apparatus obtains a codepoint value and determines at least one table entry for precoding based on the codepoint value. The codepoint value indicates selection of a transmission mode and one or multiple maximum ranks, and at least a maximum rank of a first codepoint value is different from a maximum rank of a second codepoint value. Through this solution, multi-panel simultaneous transmission in the scenarios of single and multiple transmission-reception points (TRPs) can be supported in a simple and easily adoptable way.

• Simplified Explanation:

- The patent application discusses methods and apparatuses for codebook-based uplink transmission. - A first apparatus determines precoding based on a codepoint value, which indicates the transmission mode and maximum ranks. - This allows for multi-panel simultaneous transmission in various scenarios.

• Key Features and Innovation:

- Utilizes codepoint values to determine precoding for uplink transmission. - Supports multi-panel simultaneous transmission in different scenarios. - Enables selection of transmission mode and maximum ranks based on the codepoint value.

• Potential Applications:

- 5G and beyond wireless communication systems. - Internet of Things (IoT) devices. - Mobile communication networks.

• Problems Solved:

- Facilitates multi-panel simultaneous transmission. - Simplifies the adoption of different transmission modes. - Enhances uplink transmission efficiency.

• Benefits:

- Improved uplink transmission performance. - Enhanced flexibility in selecting transmission modes. - Simplified implementation of multi-panel simultaneous transmission.

• Commercial Applications:

- Title: "Enhanced Uplink Transmission Technology for Wireless Communication Systems" - Potential commercial uses in telecommunications companies. - Market implications in the development of advanced wireless communication technologies.

• Questions about Codebook-Based Uplink Transmission:

1. How does the use of codepoint values improve uplink transmission efficiency? - The use of codepoint values allows for the selection of transmission modes and maximum ranks, optimizing the precoding process for enhanced performance.

2. What are the key advantages of supporting multi-panel simultaneous transmission? - Supporting multi-panel simultaneous transmission enables efficient communication in scenarios with single and multiple transmission-reception points, enhancing overall system capacity and flexibility.

Example embodiments of the present disclosure relate to methods and apparatuses for codebook-based uplink transmission. A first apparatus obtains a codepoint value and determines at least one table entry for precoding based on the codepoint value. The codepoint value indicates selection of a transmission mode and one or multiple maximum ranks, and at least a maximum rank of a first codepoint value is different from a maximum rank of a second codepoint value. Through this solution, multi-panel simultaneous transmission in the scenarios of single and multiple transmission-reception points (TRPs) can be supported in a simple and easily adoptable way.
