ACK/NACK Resource Allocation Offset for Interference Reduction

The patent segments the ACK/NACK resource space by introducing user equipment-specific offsets (noffsetUE) that divide the resource domain into dedicated sub-regions for different UEs. This segmentation prevents multiplexed signals from overlapping in the same resource elements, thereby reducing inter-UE interference while maintaining high resource utilization through controlled sharing of the segmented space.

The patent applies local quality by assigning different offset values (noffsetUE) to different user equipments based on their specific characteristics such as cell ID, UE ID, or resource block indices. This creates locally optimized resource allocation where each UE experiences minimal interference from others, while the overall system maintains efficient resource multiplexing through the coordinated use of these localized offset assignments.

The patent introduces a new dimension in the resource allocation space by adding user equipment-specific offsets (noffsetUE) to the traditional resource block and subcarrier allocations. This dimensional expansion allows the system to multiplex more UEs in the frequency-time-offset space while maintaining orthogonal separation, thereby increasing system capacity without sacrificing the reliability of ACK/NACK signal transmission.

The patent uses the offset value (noffsetUE) as an intermediary parameter that mediates between the conflicting goals of high system capacity and reliable transmission. By calculating and applying this intermediary offset based on UE-specific parameters, the system achieves coordinated resource allocation that simultaneously supports high capacity through multiplexing and high reliability through interference avoidance.
