Accommodating Machine-to-Machine applications and their requirements is one\nof the challenges on the way from LTE towards 5G networks. The envisioned high\ndensity of devices, alongside with their sporadic and synchronized transmission\npatterns, might create signaling storms and overload in the current LTE\nnetwork. Here, we address the notorious random access (RA) challenge, namely,\nscalability of the radio link connection establishment protocol in LTE\nnetworks. We revisit the binary countdown technique for contention resolution\n(BCCR), and apply it to the LTE RA procedure. We analytically investigate the\nperformance gains and trade-offs of applying BCCR in LTE. We further\nsimulatively compare BCCR RA with the state-of-the-art RA techniques, and\ndemonstrate its advantages in terms of delay and throughput.\n
