摘要:

Joint user pairing and power allocation approach is investigated to meet the rate requirement of enhanced mobile broadband (eMBB) slicing and delay constraint of ultra-reliable low-latency communication (URLLC) slicing simultaneously in downlink non-orthogonal multiple access ( NOMA) system. For maximizing the proportional fairness among mobile terminals, a two-step algorithm is proposed. For a given user sets, the optimal user pairing sets and the factor of the power allocation in a group were obtained to ensure the quality of service (QoS) and the isolation between different types of slicings. Simulation results show that the proposed joint algorithm can provide better throughput than orthogonal multiple access (OMA).

Abstract:

Joint user pairing and power allocation approach is investigated to meet the rate requirement of enhanced mobile broadband (eMBB) slicing and delay constraint of ultra-reliable low-latency communication (URLLC) slicing simultaneously in downlink non-orthogonal multiple access ( NOMA) system. For maximizing the proportional fairness among mobile terminals, a two-step algorithm is proposed. For a given user sets, the optimal user pairing sets and the factor of the power allocation in a group were obtained to ensure the quality of service (QoS) and the isolation between different types of slicings. Simulation results show that the proposed joint algorithm can provide better throughput than orthogonal multiple access (OMA).
