Original Abstract Submitted

the present optimization of guard bands repurposes some guard band spectrum for data transmission in a 5g network. this approach takes spectrum that is otherwise “wasted” for guard bands to enable overall spectrum utilization to be increased. to mitigate effects of inter-numerology interference (ini) with narrower guard band bandwidth, physical resource blocks (prbs) for particular user equipment (ue) are allocated to bwps that are modified with increased bandwidth that comes from narrowing the guard band bandwidth. these particular ues have high signal strength, for example, as characterized by sinr (signal-to-interference plus noise ratio), relative to other ue. allocating prbs for high signal strength ue in bwps near the edges of the narrower guard band increases the risk of ini, but the higher signal strength for these ue helps to lessen the ini impact and enable overall throughput for all users to be maximized in the network.
