Solution Overview

Problem

Current 5th Generation (5G) radio access networks face challenges in achieving flexible acknowledgement signaling while minimizing signaling overhead, particularly in dynamic control signaling processes.

Innovation Solution

The method involves transmitting control signaling with a bit pattern that includes a subpattern with M bits, where M1 bits represent an assignment indication and M2 bits represent a resource indication, both determined based on a size indication related to the feedback signaling, allowing for flexible interpretation of the bit pattern based on size thresholds.
