Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for providing feedback on downlink messages in wireless communications systems fail to efficiently handle the varying complexities of different message types, leading to inefficiencies in message transmission and processing, particularly in scenarios involving carrier aggregation and special downlink scenarios.
Innovation Solution
Implementing a method for wireless communications systems to monitor and transmit feedback messages using a set of multiple control information messages, where the quantity of bits used for feedback is determined by the type of control information message, allowing for efficient and optimized feedback transmission.

Engineering Contradiction Analysis
1Productivity
If a fixed quantity of bits is used for feedback transmission regardless of message type, then the feedback structure remains simple and uniform, but transmission overhead increases and efficiency decreases for simpler message types
Solution Approach 1:
The patent implements dynamic feedback bit allocation where the quantity of bits used for feedback transmission varies based on the type of control information message. Different message types (e.g., carrier aggregation scenarios vs. special downlink scenarios) are assigned different bit quantities, allowing the system to adapt feedback overhead to actual needs rather than using a fixed uniform structure.
Solution Approach 2:
The patent applies different feedback bit quantities to different local contexts or message types. Specifically, certain control information messages receive higher bit allocation while others receive lower allocation, optimizing the feedback structure for each specific message type's requirements rather than applying a uniform standard across all messages.
2Quantity of substance
If variable bit quantities are used for different control information message types, then transmission overhead is reduced and efficiency improves, but the feedback structure complexity increases
Solution Approach 1:
The patent changes the parameter of feedback bit quantity based on the control information message type. By dynamically adjusting this parameter, the system reduces overall feedback overhead while managing complexity through defined rules for when to use which bit quantity, rather than maintaining a single complex structure for all cases.
3Ease of operation
If uniform feedback structure is used for all control information messages, then processing is simpler, but it fails to efficiently handle varying complexities of different message types
Solution Approach 1:
The patent introduces dynamic adaptation in feedback processing where the structure and bit quantity vary according to the specific control information message type being processed. This allows the system to maintain simplicity for straightforward cases while providing enhanced capability for complex scenarios, improving overall processing efficiency without uniformly increasing complexity.

AI summary
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may monitor for multiple control messages, including a first control message, that each schedule one or more downlink messages, where a difference between a first value of a counter field in the first control message and a second value of the counter field of a previous control message of the multiple control messages may be based on whether the first control message is associated with a first type of control message or a second type of control message. Additionally, the UE may transmit a feedback message including at least a quantity of bits for indicating feedback for one or more first downlink messages associated with the first control message, where the quantity is based on whether the first control information message is associated with the first type of control message or the second type of control message.
