Combined Acknowledgement Feedback Using Decoding Event Subsets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in processing and transmitting acknowledgement feedback, particularly in managing subsets of possible decoding events, which leads to increased processing power consumption and network overhead.
Innovation Solution
Implementing a method where user equipment (UE) and base stations monitor and transmit combined acknowledgement feedback indicating subsets of possible decoding events, optimizing the number of bits used to reduce processing power and network overhead by aggregating acknowledgement information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional acknowledgement feedback methods are used for each message separately, then complete decoding information is transmitted to the base station, but processing power consumption and network overhead increase
Solution Approach 1:
The patent combines multiple individual acknowledgement feedback bits into a single consolidated feedback message. Instead of transmitting separate ACK/NACK bits for each message, the system merges them into one feedback transmission that conveys the decoding status of multiple messages simultaneously, thereby reducing processing overhead and energy consumption while maintaining complete information delivery.
Solution Approach 2:
The consolidated acknowledgement feedback mechanism serves multiple functions simultaneously: it provides decoding status for multiple messages, reduces network overhead, and lowers processing requirements. This multi-functional approach allows a single feedback transmission to replace multiple separate feedback operations.
2Loss of information
If individual acknowledgement bits are transmitted for each message, then complete decoding status is reported, but network overhead increases
Solution Approach 1:
Multiple individual acknowledgement bits are merged into a single consolidated feedback message. This combining process reduces the total quantity of data transmitted over the network while preserving all essential decoding status information, thereby reducing network overhead without information loss.
3Use of energy by moving object
If subsets of possible decoding events are used to reduce feedback bits, then processing power and network overhead are reduced, but feedback information becomes less detailed
Solution Approach 1:
The system changes the parameter of feedback representation by using a compact subset encoding scheme. Instead of transmitting detailed individual bits for each message, the feedback is transformed into a condensed representation that uses fewer bits while still conveying the essential decoding event information through mathematical relationships and base station reconstruction algorithms.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may monitor for two or more messages from a base station. The UE may transmit, to the base station, at least one bit (e.g., in first stage uplink control information (UCI)) that is based at least in part on combined acknowledgement feedback associated with the two or more messages and that indicates a subset of possible decoding events associated with the two or more messages. In some aspects, the UE may further transmit at least one additional bit (e.g., in second stage UCI) that is based at least in part on the combined acknowledgement feedback and that indicates a different subset of possible decoding events associated with the two or more messages. Numerous other aspects are described.
