Performance of Random Access in M2M for LTE System
Abstract:M2M will be important in the early LTE. Random access procedure is the first step for UE to communicate with the network in mobile telecommunication systems. An efficient random access procedure has great significance on LTE system performance. Therefore, the study of performance of random access in M2M for LTE system is very important. This paper first introduces M2M and the progress of random access. Then performance of random access in M2M for LTE system is analyzed. And an improvement is presented to enhance the performance of random access for LTE system.
Keywords: random access LTE M2M backoff
