Cell Scheduling Asymmetry for Inter-Cell Interference Reduction

The patent applies asymmetry by determining different allocation orders for unit resources in different cells. Specifically, even-numbered cells use one allocation order while odd-numbered cells use another, creating asymmetric resource allocation patterns across the network. This asymmetric approach distributes scheduling occupancy rates unevenly across cells, preventing concentration at the same time locations and thereby reducing inter-cell interference while maintaining scheduling efficiency.

The patent implements local quality by allowing each cell to have its own specific allocation order tailored to its characteristics (even or odd cell index). Instead of applying a uniform allocation order globally, the system adapts the allocation order locally to each cell's position in the network, creating differentiated resource allocation patterns that reduce interference while maintaining overall system coordination.

The patent applies periodic action by distributing resource allocations across multiple time slots in a periodic pattern determined by the allocation order. Instead of concentrating all allocations in the first slot, the system cycles through different time slots according to the determined allocation order, creating a periodic distribution pattern that maintains scheduling speed while reducing interference and improving transmission reliability.
