Binary contention resolution for M2M random access prioritization in LTE-A and 5G

Abstract

Abstract-Accommodating Machine-to-Machine (M2M) applications and their requirements is one of the challenges on the way from LTE towards 5G networks. A notorious bottleneck for supporting M2M in LTE is the Random Access (RA) procedure for network connection establishment. To address the limitations of LTE RA, we introduce here the idea of Binary Contention Resolution (BCR), a simple and efficient method for prioritizing the devices during RA. Preliminary simulative evaluation shows the gains of using BCR in comparison to state-of-the-art.
