关键扩展c1 //c1是什么意思?
-
RRC连接建立, R8版本
-
无线资源配置专用
-
添加SRB
-
建立SRB1
-
?
-
SRB采用AM接收模式. 关于模式: 透明模式™, 非确认模式(UM)和确认模式(AM)
-
UE侧的上行RLC配置, 主要配置RLC数据接收侦测规则. SRB1上下行采用AM RLC模式
-
AMD PDU重传检测定时器时长. 发送端发送某个Poll的AMD PDU后, 如果在该定时器超时后, 还没有收到响应, 则重新触发Poll.
-
UE触发Polling的PDU字节数据量门限. 轮询间隔SDU数, 该参数给出了一个触发轮询的门限值, 发送了PollSDU个SDU后触发一次轮询. 此处的p128对应为128个PDU
-
PollByte为AM PDU侦测字节数. 触发每个pollByte字节的一个轮询. 此处kB125对应125kB
-
UE AM模式RLC ARQ最大重传次数. 该参数用于配置UE,表示RLC ARQ最大重传次数,用于限制一个AM PDU的重传次数. 当等于该值时,将向高层上报不可恢复的错误,触发RRC连接重建. t16对应16次重传输.
-
UE侧的下行RLC配置,主要配置RLC数据接收状态上报规则.
-
UE AM模式接收端重排序定时器, 用于触发RESET PDU的重传. 该参数用于配置UE,表示AM 模式接收端重排序定时器的大小. 此处ms80表示80ms.
-
UE禁止发送状态报告定时器. 该参数用于配置UE表示AM模式接收端禁止发送状态报告的定时器大小. 即在本时长内不允许上报状态报告. ms15表示15ms.
-
SRB1的逻辑信道配置
-
SRB1逻辑信道优先级, 值越小优先级越高. UE调度器按逻辑信道优先级由高到低优先速率; 所有业务优先速率保证后, 按逻辑信道优先级由高到低依次分配资源.
-
SRB1逻辑信道优先速率. UE调度器按逻辑信道优先级由高到低依次保证逻辑信道的优先速率. Infinity仅仅适用于SRB1和SRB2.
-
SRB1 bucket size调整持续时间, 300ms
-
根据业务的不同, UE可能建立大量的无线承载(radio bearer, 每个bearer对应一个逻辑信道), 如果为每一个逻辑信道上报一个BSR, 会带来大量的信令开销. 为了避免这种开销, LTE引入了LCG(Logical Channel Group)的概念, 并将每个逻辑信道放入一个LCG(共4个)中. UE基于LCG来上报BSR, 而不是为每个逻辑信道上报一个BSR. 某个逻辑信道所属的LCG是在逻辑信道建立时通过IE: LogicalChannelConfig 的logicalChannelGroup字段来设置的 . CCCH, SRB1, SRB2默认属于LCG 0
-
MAC层主要配置
-
UL HARQ的最大传输次数.
-
周期性BSR上报定时器(子帧). ENUMERATED {sf5, sf10, sf16, sf20, sf32, sf40, sf64, sf80,sf128, sf160, sf320, sf640, sf1280, sf2560,infinity, spare1},infinity表示去使能.
-
SR重传定时器(子帧).为提高BSR的健壮性, LTE提供了一个重传BSR的机制: 这是为了避免UE发送了BSR却一直没有收到UL grant的情况. eNodeB通过IE: MAC-MainConfig的retxBSR-Timer字段为UE配置了一个timer, 当该timer超时且UE的任意一个LCG的任意一个逻辑信道里有数据可以发送时, 将会触发BSR. ENUMERATED {sf320, sf640, sf1280, sf2560, sf5120,sf10240, spare2, spare1}
-
TTI捆绑只对FDD有效, 对TDD仅仅适用于配置为0, 1以及6的情况. FALSE不绑定, TURE表示TTI捆绑有效.
-
RX-Config : release
-
上行时间对齐定时器, 该参数表示UE上行时间对齐的定时器长度, 该定时器超时, 则认为UE上行失步. 取值范围: SF500(500个子帧), SF750(750个子帧), SF1280(1280个子帧), SF1920(1920个子帧), SF2560(2560个子帧), SF5120(5120个子帧), SF10240(10240个子帧), INFINITY(无穷大)
-
功率余量报告配置, PHR(power headroom report)
-
功率余量报告周期定时器
-
禁止上报功率剩余报告定时器
-
PHR报告的下行路径损耗变化. ENUMERATED {dB1, dB3, dB6, infinity} 什么时候报告功率余量? 功率余量报告定时器: 当UE有传输新数据的上行资源, prohibitPHR-Timer 超时或者已经超时且在上次传输功率余量报告之后, 路径损耗的变化值大于dl-PathlossChange dB. 触发功率余量报告(PHR); periodicPHR-Timer超时, 触发功率余量报告
-
物理层配置专用
-
PDSCH配置专用
-
PA=0 //?
-
PUCCH配置专用
-
此处"release"为清除此配置以及停止使用相关资源. 若设置为"setup", 采用相应的接收配置以及开始使用相关的资源.
-
TDD-确认非确认反馈模式 绑定模式
-
PUSCH配置专用
-
ACK随路偏置索引, 该参数表示ACK随路偏置索引. INTEGER (0..15)
-
RI随路偏置索引, 该参数表示RI随路偏置索引. INTEGER (0..15)
-
CQI随路偏置索引, 该参数表示RI随路偏置索引. INTEGER (0..15)
-
上行链路功控专用
-
INTEGER (-8..7) //?
-
根据不同MCS格式调整UE发射功率的开关. 取值范围(0:不能够; 1:能够)
-
累积使能, (0:不能够; 1:能够) //?
-
INTEGER (-8..7) //?
-
SRS相对PUSCH的功率偏置, INTEGER (0..15)
-
//?
-
RSRP滤波系数. 该参数表示UE估算路损过程中, 对RSRP测量值进行滤波的alpha滤波系数.
-
CQI配置
-
//?
-
天线配置
-
传输模式TM2, 标识UE所使用的传输模式
-
终端UE传输天线选择, Setup或release. Setup表示开环或者闭环. //?
-
调度请求配置信息
-
调度请求配置信息类型setup
-
SR PUCCH资源索引, SR(资源调度请求), BSR(上行数据缓冲域状态报告过程)根据规范BSR过程: UE在收到网络端的逻辑信道配置信息后, 根据其中的逻辑信道标识号, 优先级, 逻辑信道组等信息, 将每个逻辑信道归属于固定的逻辑信道组. BSR主要功能是向eNB报告UE端上行数据缓冲域中的数据量, 从而能够从eNB获取上行资源来传输缓冲域中的数据. MAC层触发了BSR过程之后, 如果没有传输BSR的资源则立即触发SR过程, 向eNB申请至少4字节的上行资源以便能够传输BSR及其对应的MAC字头. 两者关系可类似于一阶段接入和二阶段接入的关系.

SRB增加模式列表
-
增加SRB2, SRB2: 用于传传NAS消息的, 它必须在安全激活后才能被建立起来. 确保信令的安全性. SRB1是传送RRC信令的, 在SRB2建立前也传NAS消息, SRB2建立后SRB1就只用于传RRC信令了. 重配置等消息就是在SRB1上传送的.
-
SRB为保证信令的正确接收配置为AM模式
-
UL-AM-RLC为针对UE侧的上行RLC配置, 主要配置RLC数据接收侦测规则.
-
AM PDU重传检测定时器时长.
-
UE触发Polling的PDU字节数据量门限. 此处配置为128
-
PollByte为AMD PDU侦测字节数. 此处配置为kB.
-
UE AM模式RLC ARQ最大重传次数. 该参数用于配置UE, 表示RLC ARQ最大重传次数, 用于限制AM PDU的重传次数. 达到最大重传次数时会触发RRC连接重建.
-
下行确认RLC模式
-
UE AM模式接收端重排序定时器. 该参数用于配置UE, 表示AM模式接收端重排序定时器的大小.
-
UE禁止发送状态报告定时器. 该参数用于配置UE, 表示AM模式接收端禁止发送状态报告的定时器大小. 即在本时长内不允许上报状态报告.
-

DRB增加模式列表
-
添加第一个DRB列表
-
由MME分配, 端到端的承载, 即erab ID为5. 建立了erab 和 DRB的关系
-
DRB的ID, 由eNB分配, 无线侧数据承载
-
指定了该DRB的PDCP层处理配置
-
PDCP层丢弃定时器,根据QCI的不同设置值不同, 比如QCI6/8/9是无限长, QCI2/7是150ms. 此处为无限大
-
AM模式切换时PDCP状态报告反馈指示. 如果配置为False, 目标eNodeB将传输所有源eNodeB转发的数据, 其中某些数据UE可能已收到, 造成空口资源的浪费. 如果为TRUE需要发一个状态报告.
-
头压缩, 一般只在VoIP, 视频类的业务中才会根据eNB侧的配置决定是否启用. 该值默认关闭.
-
指定了该DRB在RLC处理配置
-
AM确认模式
-
上行RLC确认模式, 针对UE侧的配置
-
UE Polling PDU重传定时器大小. 该定时器设置过小会触发过多的Polling PDU, 且连续多次触发PDU重传使ARQ重传达到最大次数, 从而导致RRC重建; 设置过大会导致状态报告不能及时的反馈. 40ms(QCI4/5/6/8/9)
-
UE 触发Polling的PDU字节数据量门限. 表示触发Polling的PDU数据量门限. 当PDU发送数据量达到该值时, 将在PDU头部设置Poll标志位. (满足个数或字节数其中一个条件就会启动POLL机制). 该参数是发送端为了防止等待确认队列太长导致缓冲区溢出, 根据发送PDU的数据量主动触发状态报告. 取值过小可能增加Polling PDU的触发次数; 取值过大则缓冲占用越大, 且会减慢发送窗的移动.
-
PollByte为AMD PDU侦测字节数.
-
UE AM模式RLC ARQ最大重传次数. 该参数用于配置UE, 表示RLC ARQ最大重传次数, 用于限制AM PDU的重传次数. 达到最大重传次数时会触发RRC连接重建. 32(QCI4/5/6/8/9)
-
为针对UE侧的下行RLC配置, 主要配置RLC数据接收状态上报规则.
-
UE AM模式接收端重排序定时器. 如果该定时器配置较小, 则导致发送端无效的HARQ重传及接收端触发重复的状态报告, 浪费资源; 如果配置过大, 则导致接收端判断乱序包传输失败延时较大, 不能及时的触发状态报告, 从而造成业务延时和吞吐量下降. 默认50ms
-
UE禁止发送状态报告定时器. 即在本时长内不允许上报状态报告. 该定时器影响AM模式下状态报告的发送. 如果状态报告发送不频繁, 可以减少状态报告的频繁调度, 但容易导致发送端发送窗口为0, 降低发送速率; 如发送频繁, 则可以保证发送端发送窗口数据及时得到确认, 保证发送速率, 但容易导致数据状态报告的频繁调度和重复发送, 浪费资源. 默认值50ms
-
对应逻辑信道ID
-
DRB逻辑信道配置
-
逻辑信道优先级. UE调度器按逻辑信道优先级由高到低依次保证逻辑信道的优先速率; 所有业务优先速率保证后, 按逻辑信道优先级由高到低分配资源, 仅在QCI为6, 7, 8, 9时该参数有效. 取值范围9 ~ 16, 默认值QCI6:9; QCI7:10; QCI8:11; QCI9:12
-
逻辑信道优先速率. UE调度器按逻辑信道优先级由高到低保证逻辑信道的优先速率, 仅在QCI为2, 3, 4, 6, 7, 8, 9时有效. PBR_8_KBps(8千字节/秒)
-
bucket size调整持续时间
-
逻辑信道组. CCCH, SRB1, SRB2默认属于LCG 0; RRC消息在SRB上传输且SRB默认属于LCG 0, 比LCG 2的优先级要高.
