4 同步过程
4.1 小区搜索
小区搜索是指UE在小区中获取时间和频率同步并检测小区物理层Cell ID的过程。E-UTRA小区搜索支持包含6个以上资源块的传输带宽范围内的搜索。
通过主同步信号和辅同步信号的发送实现下行链路的小区搜索。
4.2 时间同步
4.2.1 无线链路监测
UE应该监测服务小区无线链路的质量，因为UE要把探测到的同步状况传给高层，
在非DRX（Discontinuous Receptio，省电模式）模式操作，UE的物理层在每个无线帧都要检测无线链路质量，并通过前一时间段[200ms]周期测得 ，这个无线链路质量的检测依赖于门限Qout and Qin（在[10]相关测试中被隐含定义）。
在DRX模式操作，UE的物理层至少每个DRX阶段都要检测无线链路质量，并通过之前的周期[10中定义]测得。这个无线链路质量的检测依赖于门限Qout and Qin（在[10]相关测试中被隐含定义）。
UE的物理层 在检测无线链路质量的无线帧中指示同步情况并上报给高层：当无线链路质量比门限值Qout差时，指示为失同步；当无线链路质量好于Qin时，指示为同步。
4.2.2 小区间同步
例如，用于有多播物理信道的小区。
4.2.3 传输定时校正
收到定时提前命令后，UE应该调整PUCCH/PUSCH/SRS的上行发送时间。定时提前命令表示为16的整数倍,它和当前上行时间相关。随机接入前导的起始时间在211中设定。
随机接入响应中，时间提前命令TA,为11bit，通过索引值TA = 0, 1, 2, ..., 1282,来表示NTA值，其中时间序列的数据由NTA = TA ´16给出。NTA在[3]中定义。
其它情况下，时间提前命令TA,为6bit，指示当前NTA值相对于新的NTA值NTA,new,的校正，其中索引值TA = 0, 1, 2,..., 63, NTA,new = NTA,old + (TA -31)´16.这里，NTA 值的校正是通过一个正的或负的数据，根据给出的数据分别来指示上行传输定时的时间提前或延迟
子帧n上接收到时间提前命令，相应的定时校正从子帧n+6的开始来进行。当由于时间校正，UE的子帧n和n+1中传输的上行PUCCH/PUSCH/SRS有重叠，UE应传输完整的子帧n，而不传输子帧n+6的重叠部分。
如果接收到的下行定时发生改变，没有[10]中所提到的时间提前要求，上行定时校正不再补偿或只是部分补偿,那么UE随之改变NTA。

5 功率控制
下行功率控制决定单位资源元素上的功率值，可见是在频域进行功率分配再进行时域加CP，同时功率分配是进行在子载波上，是对各个复信号上的幅度的调整。上行功率控制决定所传输的DFT-SOFDM符号上的功率值。
5.1 上行功率控制
上行功率控制控制着不同物理信道的发送功率值。
