LTE 各种英文缩写解释

<1>RAN 无线接入网<2>RNC 无线网络控制器负责对基站进行整体管理, 包括对无线资源、本地移动用户和接入情况进行管理和控制, 并对传输情况进行优化; RNC的主要功能为无线资源管理, 网络相关功能、无线资源控制(RRC)的维护和运行, 网管系统的接口等。

RNC的主要缺点为与空中接口相关的许多功能都在RNC中, 导致资源分配和业务不能适配信道, 协议结构过于复杂, 不利于系统优化。

<3>HSDPA 高速下行链路分组接入，是一种移动通信协议，亦称为3.5G(3½G)。

该协议在WCDMA下行链路中提供分组数据业务，在一个5MHz载波上的传输速率可达8-10 Mbit/s（如采用MIMO技术，则可达20 Mbit/s）。

在具体实现中，采用了自适应调制和编码（AMC）、多输入多输出（MIMO）、混合自动重传请求（HARQ）、快速调度、快速小区选择等技术。

<4>SGSN 服务支持节点负责管理分组交换数据流量的控制和管理。

<5>GGSN 网关支持节点负责与核心网的连接。

GGSN 是本地网与外部分组交换网之间的网关, 因此也被称为GPRS路由器<6>ACGW 核心接入网关AGW 接入网关<7>RRC 无线资源控制子层<8>RLC 无线链路控制<9> PDU 协议数据单元<10>ACK 确认应答<11>FEC 前向纠错<12>ACK命令正确应答<13>OFDMA 正交频分多址<14>OFDM 正交频分复用实际上OFDM是MCM Multi-CarrierModulation，多载波调制的一种。

其主要思想是：将信道分成若干正交子信道，将高速数据信号转换成并行的低速子数据流，调制到在每个子信道上进行传输。

正交信号可以通过在接收端采用相关技术来分开，这样可以减少子信道之间的相互干扰ICI 。
