Query: CoMP Enhanced Subcarrier and Power Allocation for Multi-Numerology based
  5G-NR Networks   With proliferation of fifth generation (5G) new radio (NR) technology, it is
expected to meet the requirement of diverse traffic demands. We have designed a
coordinated multi-point (CoMP) enhanced flexible multi-numerology (MN) for
5G-NR networks to improve the network performance in terms of throughput and
latency. We have proposed a CoMP enhanced joint subcarrier and power allocation
(CESP) scheme which aims at maximizing sum rate under the considerations of
transmit power limitation and guaranteed quality-of-service (QoS) including
throughput and latency restrictions. By employing difference of two concave
functions (D.C.) approximation and abstract Lagrangian duality method, we
theoretically transform the original non-convex nonlinear problem into a
solvable maximization problem. Moreover, the convergence of our proposed CESP
algorithm with D.C. approximation is analytically derived with proofs, and is
further validated via numerical results. Simulation results demonstrated that
our proposed CESP algorithm outperforms the conventional non-CoMP and single
numerology mechanisms along with other existing benchmarks in terms of lower
latency and higher throughput under the scenarios of uniform and edge users.
