RNTP-based coordinated resource allocation in 3D emergency networks

Abstract

This paper partitions original user and emergency user specific downtilts through dynamic vertical beamforming in 3-dimension (3D) emergency networks. The coordination scheme aims to maximize the throughput of both original users and emergency users, subject to per wireless access point (AP) power and downtilt constraints. We propose a relative narrow-band transmit power (RNTP) based coordinated resource allocation scheme to solve this optimization problem, by interacting RNTP bit maps among eNBs. Here, power and downtilts adjustment, resource block (RB) allocationare jointly optimized. Simulation results show that such RNTP-based resource allocation scheme is efficient.
