Downlink Next Generation Wireless Networks Interference Resource Allocation

Abstract

This study provides a unique downlink allocation strategy for next-generation wireless networks based on OFDMA that have intercell interference (ICI).  The method involves radio resources and separately executed power allocations.  In order to reach a radio resource allocation, low-complex heuristic methods are initially suggested in which graphical structures and the fine physical resource block (FPRs) are assigned to reduce large ICIs and therefore enhance the network performance. A new distributed power allotment is created in order to develop the cell-edge users’performance. Using a radio resource allocation approach, provided that required performance is maintained for cell center users.

Power development is given as an iterative water filling problem with limited obstacles and solved using the Lagrange method. Simulation data show that our proposed system may considerably increase cell and cell center users' performance over present multicell networks, thereby fulfilling the goal of future wireless networks to deliver excellent performativity for everybody.
