摘　　要：上行接入为用户设备UE(UserEquipment)接入网络提供上行支撑,是移动通信不可或缺的重要组成部分。优秀、高效的上行接入技术可以大大提高上行链路的频谱效率,增加系统容量,扩大覆盖范围,最大化的减小时延。本文通过对LTE(LongTimeEvolution)标准中上行接入技术的研究,较为全面地对LTE环境下上行接入进行了分析和介绍。Uplink access support the user equipment to access networks. It is an indispensable and important component of the mobile communications. Excellent and efficient uplink access technologies can greatly enhance the uplink spectral efficiency, increase system capacity, expand coverage and reduce the maximum delay. This paper researches and analysis the LTE uplink access standard and key technologies. Finally introduced the environment for LTE uplink access.
