Coded Slotted ALOHA (CSA),ence between the PHY layer schemes and the MAC layer schemes is that the PHY layer solutions are used for the single slot transmission process while the MAC layer solutions are used for multi-slot transmission process. In CSA, each served UE selects multiple time slots to transmit the replica of its

Tandem Spreading Multiple Access, access scheme to cover both high connectivity and reliability in grant-free random access system is potentially demanded by the future MTC applications. Motivated by this, a novel spreading based multiple access technique named . has been proposed. This approach is initiated from the scheme called

Conclusion,C scenario are described. For the sake of saving the enormous control signaling overheads in the small data packet transmissions, grant-free random access is regarded as a suitable random access procedure for mMTC. Nevertheless, new challenges including anonymous transmission and collision are arise
