TD-LTE网络随机接入前导码规划分析

摘要

Terminal access TD-LTE network must pass through random access processing, it’s also the only policy of user-initiated connections, switches, connections to establish and restore the uplink synchronization. The failure rate will affect the TD-LTE network access performance. This article focuses on TD-LTE network random access preamble planning and the automatic plan of preamble.%TD-LTE网络随机接入是终端接入网络的必经过程，是用户进行初始连接、切换、连接重建立以及重新恢复上行同步的唯一策略，其失败率会影响TD-LTE网络的接入性能。本文中重点介绍TD-LTE网络随机接入前导码的精细规划，以及随着网络割接调整而实施的前导码自动规划。
