Machine type communication (MTC) is a typical scenario in 5G communication systems, and massive machine type communication (MMTC) is a main type of MTC. One prominent characteristic of MMTC is massive connections and sporadic transmission with short packets. To embrace the new challenge in 5G emerging scenarios, flexible filterbased waveforms have been widely studied recently. In this paper, we evaluate...
One of 5G communication typical scenarios is machine-to-machine communication with large number of devices, which proposes new requirements for uplink transmission. Filter bank multi-carrier with offset quadrature amplitude modulation (FBMC/OQAM) is one of the popular nonorthogonal waveform candidates for 5G transmission. In this paper, FBMC/OQAM and cyclic prefix OFDM with single antenna settings...
The contention-based (CB) transmission is a promising solution for small data packets transmission in 5G uplink. In this paper, a Non-Orthogonal Coded Access (NOCA) scheme, called ZC-NOCA, is proposed for CB transmission in 5G uplink. For ZC-NOCA, the codes generated by Zadoff-Chu (ZC) sequences is used to spread the data bit over the Orthogonal Frequency Division Multiple (OFDM) symbols. Different...
With the rise of the user base of smartphones, the cellular networks are facing increasing uplink signalling traffic pressure caused mainly by the soaring background traffic of smartphone applications. Therefore, this paper studies the LTE radio resource control (RRC) state transition, which is highly related to the amount of signalling traffic, caused by the background traffic. Firstly, we propose...
