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 。

LTE-各种英文缩写解释

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 。

LTE缩略语

PDCP:Packet Data Convergock），码字（codeword），层映射（layer mapping），传输层（transmission layer）, 阶（rank）, 和预编码（Precoding），天线端口（antenna port）是LTE物理层的几个基本概念，搞清楚这几个概念的定义和相互关系才能透彻理解LTE多天线技术和调度算法。
LTE定义了最多4个小区级天线端口，因此UE能得到四个独立的信道估计，每个天线端口分别对应特定的参考信号模式。为了尽量减小小区内不同的天线端口之间的相互干扰，如果一个资源元素（Resource element）用来传输一个天线端口的参考信号，那么其它天线端口上相应的资源元素空闲不用。
LTE还定义了终端专用参考信号，对应的是独立的第5个天线端口。终端专用参考信号只在分配给传输模式7（transmission mode）的终端的资源块（Resource Block）上传输，在这些资源块上，小区级参考信号也在传输，这种传输模式下，终端根据终端专用参考信号进行信道估计和数据解调。终端专用参考信号一般用于波束赋形（beamforming），此时，基站（eNodeB）一般使用一个物理天线阵列来产生定向到一个终端的波束，这个波束代表一个不同的信道，因此需要根据终端专用参考信号进行信道估计和数据解调。
总之，一个天线端口就是一个信道，终端需要根据这个天线端口对应的参考信号进行信道估计和数据解调。
码字个数、阶和天线端口数之间的关系
传输块个数 = 码字个数（C ）<= 阶（R）<=天线端口数（P）
PDU（Protocol Data Unit）是指对等层次之间传递的数据单位。协议数据单元(Protocol Data Unit )物理层的 PDU是数据位（bit），数据链路层的 PDU是数据帧（frame），网络层的PDU是数据包（packet），传输层的 PDU是数据段（segment），其他更高层次的PDU是数据（data）

LTE各种英文缩写解释

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。

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 。
