Base Station Frequency Scheduling for Signaling Overhead Reduction

The patent divides the frequency band into multiple resource blocks and further segments them into groups. By performing distributed assignment on selected groups rather than all individual resource blocks, the system achieves frequency diversity while limiting the number of assignment patterns that need to be signaled. The segmentation allows selective application of distributed assignment to balance diversity benefits against signaling overhead.

The patent applies distributed assignment partially rather than universally across all resource blocks. Specifically, it performs distributed assignment on selected resource block groups while using localized assignment for others, or limits the distributed assignment to a subset of subcarriers. This partial application achieves sufficient frequency diversity effect while avoiding the excessive signaling overhead that would result from applying distributed assignment to all subcarriers.

The patent segments the frequency bandwidth into multiple resource block groups and applies distributed assignment selectively among these groups. This segmentation reduces the total number of assignment patterns needed compared to applying distributed assignment across the entire bandwidth, while still achieving frequency diversity by spreading assignments across multiple groups.

The patent changes the parameter of resource block group size and number of groups to optimize the balance between frequency diversity and assignment pattern complexity. By adjusting these parameters, the system can widen the effective bandwidth for diversity while keeping the number of assignable patterns manageable and reducible to fewer signaling bits.
