Unified Feedback Codebook for Mixed-Bit Uplink Multiplexing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems struggle to support codebooks that can efficiently multiplex both single-bit and multi-bit feedback into a single feedback message, leading to impaired system efficiency.
Innovation Solution
A user equipment (UE) is configured with codebook configurations that enable the simultaneous inclusion of single-bit and multi-bit feedback by generating a codebook that supports both types of feedback, allowing them to be transmitted in a common uplink transmission opportunity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate codebooks are used for single-bit feedback and multi-bit feedback, then each feedback type can be transmitted independently, but the system efficiency is impaired due to inability to multiplex both types in a single feedback message
Solution Approach 1:
The patent merges single-bit feedback codebook and multi-bit feedback codebook into a unified codebook structure that can accommodate both feedback types simultaneously. This is achieved by dividing the codebook into first and second codebook parts, where the first part contains entries for single-bit feedback and the second part contains entries for multi-bit feedback, enabling multiplexing in a single feedback message.
Solution Approach 2:
The unified codebook is segmented into distinct first and second codebook parts, each handling specific feedback types. The first codebook part corresponds to single-bit feedback entries while the second codebook part corresponds to multi-bit feedback entries, allowing organized storage and retrieval of different feedback types within a single codebook structure.
2Productivity
If a unified codebook supports both single-bit and multi-bit feedback, then feedback multiplexing is enabled, but the codebook structure becomes more complex
Solution Approach 1:
The codebook structure is segmented into clearly defined first and second codebook parts with distinct functions. The first codebook part handles single-bit feedback while the second codebook part handles multi-bit feedback, providing modular organization that reduces processing complexity despite the unified structure.
Solution Approach 2:
Different portions of the codebook are assigned different qualities and characteristics appropriate to their function. The first codebook part uses structures optimized for single-bit feedback operations while the second codebook part uses structures optimized for multi-bit feedback operations, allowing each section to be processed efficiently according to its specific requirements.

AI summary
Methods, systems, and devices for wireless communication are described. Some wireless communications systems may support codebook structures for multiplexing single-bit feedback and multi-bit feedback in a same uplink feedback message. A user equipment (UE) may receive a first downlink message associated with single-bit feedback and a second downlink message associated with multi-bit feedback. The first downlink message and the second downlink message may have a common uplink transmission opportunity for transmitting feedback pertaining to the downlink messages. The UE may generate a codebook that supports inclusion of both the singlebit feedback and the multi-bit feedback for the first and second downlink messages. The UE may transmit the feedback message during the common uplink transmission opportunity based on the codebook.
