Abstract: The fifth generation (5G) systems have greater requirements for data speeds, minimum latency, and low connection density. In hybrid MC-NOMA system, the optimal resource allocation is more challenging to achieve the commitment of energy efficiency (EE) and spectral efficiency (SE) with minimal user rate requirement. Therefore, in this manuscript, the optimal power and resource allocation for 5G oriented system using a hybrid whale and hosted cuckoo (Hyb-WHC) optimisation algorithm is proposed for solving EE resource allocation problems under MC-NOMA system. Here, the hybridised whale and hosted cuckoo (Hyb-WHC) optimisation algorithm distributes power to every network. Then the distributed power of every channel is allocated to the multiplexed users depends on their individual channel gains. The proposed approach is activated in MATLAB and its performance is compared with existing approaches, such as optimal resource allocation using lion algorithm with probabilistic mating (MC-NOMA-LAPM) and traditional fractional power allocation method (MC-NOMA-FTPA).

Keywords: Hyb-WHC optimisation; hybrid multi-carrier non-orthogonal multiple accesses; user grouping; power distribution; choice of multiple accesses; sum rate.
