主　　题：5G New Radio non-orthogona multiple access grant-free transmission 

摘      要：In this paper,the concept of grantfree non-orthogonal multiple access(NOMA) for uplink data transmission is *** in combination with grant-free can be applied to ultra reliability low latency communication(URLLC),massive machine type communication(m MTC),enhanced mobile broadband(e MBB) small packet and two-step random-access channel(RACH) *** advantages of grant-free NOMA are low latency and signaling overhead,high access capability and efficient resource *** uplink NOMA schemes are summarized and preliminary comparison among a subset of schemes are ***,design aspects for grant-free NOMA are discussed,with special notes on particular issues such as blind UE identification and transmitter/receiver(Tx/Rx) impairments in realistic deployment.
