PHR(.Power Headroom Report)LTE无线通信系统中，终端的MAC层向基站上报的发射功率余量。UE功率余量报告过程是为了向服务eNB提供UE所谓最大传输功率与当前UL-SCH传输功率估计值之间的差异信息。协议描述如下：The Power Headroom reporting procedure is used to provide the serving eNB with information about the difference between the nominal UE maximum transmit power (在下面36.101中定义)and the estimated power for UL-SCH transmission per activated Serving Cell and also with information about the difference between the nominal UE maximum power and the estimated power for UL-SCH and PUCCH transmission on PCell.从下面的协议说明可知，UE最大发射功率可以为23dBm。36.101协议中定义：PPowerClassPPowerClass is the nominal UE power (i.e., no tolerance).UE Maximum Output PowerThe following UE Power Classes define the maximum output power（PPowerClass） for any transmission bandwidth within the channel bandwidth. The period of measurement shall be at least one sub frame (1ms).Table 6.2.2-1: UE Power ClassEUTRA bandClass 1 (dBm)Tolerance (dB)Class 2 (dBm)Tolerance (dB)Class 3 (dBm)Tolerance (dB)Class 4 (dBm)Tolerance (dB)12322232232322423252326232723228232292321023211232122322132321423217232182321923220232221232242323323234232352323623237232382323923240232412324223243232Note 1:The above tolerances are applicable for UE(s) that support up to 4 E-UTRA operating bands. For UE(s) that support 5 or more E-UTRA bands the maximum output power is expected to decrease with each additional band and is FFSNote 2:For transmission bandwidths (Figure 5.6-1) confined within FUL_low and FUL_low + 4 MHz or FUL_high 4 MHz and FUL_high, the maximum output power requirement is relaxed by reducing the lower tolerance limit by 1.5 dB Note 3:For the UE which supports both Band 11 and Band 21 operating frequencies, the tolerance is FFS.Note 4:PPowerClass is the maximum UE power specified without taking into account the tolerance参考波段范围：Table 5.5-1 E-UTRA operating bandsEUTRA Operating BandUplink (UL) operating bandBS receiveUE transmitDownlink (DL) operating bandBS transmit UE receiveDuplex ModeFUL_low FUL_highFDL_low FDL_high11920 MHz 1980 MHz 2110 MHz 2170 MHzFDD21850 MHz 1910 MHz1930 MHz 1990 MHzFDD31710 MHz 1785 MHz1805 MHz 1880 MHzFDD41710 MHz1755 MHz 2110 MHz 2155 MHzFDD5824 MHz849 MHz869 MHz 894MHzFDD61830 MHz840 MHz875 MHz 885 MHzFDD72500 MHz2570 MHz2620 MHz 2690 MHzFDD8880 MHz915 MHz925 MHz 960 MHzFDD91749.9 MHz1784.9 MHz1844.9 MHz 1879.9 MHzFDD101710 MHz1770 MHz2110 MHz 2170 MHzFDD111427.9 MHz 1447.9 MHz 1475.9 MHz 1495.9 MHz FDD12699 MHz716 MHz729 MHz746 MHzFDD13777 MHz787 MHz746 MHz756 MHzFDD14788 MHz798 MHz758 MHz768 MHzFDD15ReservedReservedFDD16ReservedReservedFDD17704 MHz 716 MHz734 MHz746 MHzFDD18815 MHz830 MHz860 MHz875 MHzFDD19830 MHz845 MHz875 MHz890 MHzFDD20832 MHz862 MHz791 MHz821 MHzFDD211447.9 MHz1462.9 MHz1495.9 MHz1510.9 MHzFDD.241626.5 MHz1660.5 MHz1525 MHz1559 MHzFDD.331900 MHz1920 MHz1900 MHz1920 MHzTDD342010 MHz2025 MHz 2010 MHz 2025 MHzTDD351850 MHz 1910 MHz1850 MHz 1910 MHzTDD361930 MHz 1990 MHz1930 MHz 1990 MHzTDD371910 MHz 1930 MHz1910 MHz 1930 MHzTDD382570 MHz 2620 MHz2570 MHz 2620 MHzTDD391880 MHz 1920 MHz1880 MHz 1920 MHzTDD402300 MHz 2400 MHz2300
