Enhancing Cellular M2M Random Access with Binary Countdown Contention Resolution. (arXiv:1708.02808v2 [cs.NI] UPDATED)
来源于:arXiv
Accommodating Machine-to-Machine applications and their requirements is one
of the challenges on the way from LTE towards 5G networks. The envisioned high
density of devices, alongside with their sporadic and synchronized transmission
patterns, might create signaling storms and overload in the current LTE
network. Here, we address the notorious random access (RA) challenge, namely,
scalability of the radio link connection establishment protocol in LTE
networks. We revisit the binary countdown technique for contention resolution
(BCCR), and apply it to the LTE RA procedure. We analytically investigate the
performance gains and trade-offs of applying BCCR in LTE. We further
simulatively compare BCCR RA with the state-of-the-art RA techniques, and
demonstrate its advantages in terms of delay and throughput. 查看全文>>
