Grouping-Based Random Access Collision Control for Massive Machine-Type Communication

open access: yes, 2017
Massive Machine-Type Communication (mMTC) is expected to be strongly supported by future 5G wireless networks. Its deployment, however, is seriously challenged by the high risk of random access (RA) collision. A popular concept is to reduce RA collisions
