• The downlink channel bandwidth
  
• The PHICH configuration. The Physical Hybrid ARQ Indicator Channel carries the HARQ ACKs andNACKs for uplink transmissions
  
• The SFN (System Frame Number) which helps with synchronization and acts as a timing reference
  
• The eNB transmit antenna configuration specifying the number of transmit antennas at eNB such as 1, 2, or4, which is carried by CRC mask for PBCH
  

而系统的上行频点、上行带宽是在SIB2消息中广播的：

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

• The uplink carrier frequency and the uplink channel bandwidth (in terms of the number of Resource Blocks, for example n25, n50)
  
• The Random Access Channel (RACH) configuration, which helps a UEstart the random access procedure, such as preamble information, transmittime in terms of frame and subframe number (prach-ConfigInfo), andpowerRampingParameters which indicates the initial Tx power and rampingstep.
  
• The paging configuration, such as the paging cycle
  
• The uplink power control configuration, such as P0-NominalPUSCH/PUCCH
  
• The Sounding Reference Signal configuration
  
• The Physical Uplink Control Channel (PUCCH) configuration to supportthe transmission of ACK/NACK, scheduling requests, and CQI reports
  
• The Physical Uplink Shared Channel (PUSCH) configuration, such ashopping
