Multiple access(MA) technology is of most importance for 5G. Non-orthogonal multiple access(NOMA) utilizing power domain and advanced receiver has been co.sidered as a promising candidate MA technology recently. In this paper, the NOMA co.cept is presented toward future enhancements of spectrum efficiency in lower frequency bands for downlink of 5G system. Key co.ponent technologies of NOMA are presented and discussed including multiuser transmission power allocation, scheduling algorithm, receiver design and co.bination of NOMA with multi-antenna technology. The performance gains of NOMA are evaluated by system-level simulations with very practical assumptions. Under multiple co.figurations and setups, the achievable system-level gains of NOMA are shown promising even when practical co.siderations were taken into acco.nt.
