SIB2中的上行频点和带宽

看协议中说SIB2中包含小区的上行频点和带宽

SIB2 containsradio resource configuration information common for all UEs, including:

 The uplink carrier frequency and the uplink channel bandwidth

下面是一条SIB2消息的一部分，我想知道是怎么看出上行频点和带宽的：

value BCCH-DL-SCH-Message ::=
{
  message c1 : systemInformation :
      {
        criticalExtensions systemInformation-r8 :
          {
            sib-TypeAndInfo
            {
              sib2 :
                {
                  ac-BarringInfo
                  {
                    ac-BarringForEmergency FALSE
                  },
                  radioResourceConfigCommon
                  {

                        preamblesGroupAConfig

                          sizeOfRA-PreamblesGroupA n48,
                          messageSizeGroupA b56,
                          messagePowerOffsetGroupB dB8
                        }
                      },
