Block4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。关于小区级的过载指示
