- Abstract
- Massive connection of machine-type
communications devices is one of major issues for nextgeneration wireless communications technologies. In particular
the contention-based random access method used in long-term
evolution has many difficulties to support massive connection
scenario of next-generation wireless communications technologies.
This paper investigates the limitations in which the random
access method currently used in cellular networks is difficult to
apply to the massive connection scenario of the next-generation
network. This paper firstly described the procedure of random
access used in long-term evolution. This paper also describes the
limitations of random access technology with respect to the
collision probability and quality-of-service degradation due to
retransmission. In addition, this paper introduces candidate
solutions that can solve the described limitations of existing
random access method and support massive connection
requirements for the next-generation wireless communication
technologies.
