Random Access Procedure in LTE System
Abstract:Random access procedure is the first step for UE to communicate with the network in mobiletelecommunication systems. An efficient random access procedure has great significance on LTE system performance. This paper first introduces the progress of the random access procedure in LTE system. Then the process of the random access in the LTE protocol is given in detail, and the key mechanisms are analyzed.
