Best Effort Up Link (UL) Fractional Frequency Reuse (FFR) - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240040562 titled 'Best Effort Up Link (UL) Fractional Frequency Reuse (FFR)

Simplified Explanation

The invention described in this patent application is a method for efficiently allocating bandwidth in an uplink (UL) fractional frequency reuse (FFR) system. The method involves dividing the bandwidth into different regions and assigning user equipment (UE) to these regions.

  • The method classifies UEs as either cell-edge UEs or cell-center UEs.
  • Before each UL scheduling, the method examines each UE and updates its status.
  • The method chooses a cell-edge segment for each cell, which includes a starting and ending subcarrier (SB) index.
  • The cell-edge segment is defined using the physical cell indicator (PCI) as an input.

Potential applications of this technology:

  • Wireless communication systems
  • Cellular networks
  • Mobile network optimization

Problems solved by this technology:

  • Efficient allocation of bandwidth in UL FFR systems
  • Improved resource management in cellular networks
  • Enhanced performance for cell-edge UEs

Benefits of this technology:

  • Increased capacity and throughput in cellular networks
  • Improved user experience for cell-edge UEs
  • Simplified and efficient allocation of resources in UL FFR systems


Original Abstract Submitted

this invention relates to an efficient and simple best effort ul ffr, describing how to effectively partition the bandwidth (bw) into regions and how to allocate different ues into those partitions. in one embodiment, a method of uplink (ul) fractional frequency reuse (ffr) includes classifying a user equipment (ue) as either a cell-edge ue or a cell-center ue; examining each ue before each ul scheduling and updating a status of the ue that was examiner; and choosing a cell-edge segment for each cell, a cell-edge segment including a starting sb index and an end sb index, wherein an sb is a group of resource blocks (rbs), wherein the cell edge segment is defined using the physical cell indicator (pci) as an input.
