Full-config IE (Information Element) is a parameter sent by the eNodeB to the UE (User Equipment) in the RRC (Radio Resource Control) reconfiguration message. It contains all the necessary configuration parameters for the UE to operate in the cell.

The Full-config IE includes the following information:

  • Cell identity: This identifies the cell in which the UE is operating.
  • Physical layer parameters: These parameters include the frequency band, channel bandwidth, and modulation scheme.
  • MAC layer parameters: These parameters include the scheduling algorithm, contention resolution mechanism, and power control parameters.
  • RLC layer parameters: These parameters include the buffer size, retransmission timer, and flow control parameters.
  • PDCP layer parameters: These parameters include the ciphering algorithm, integrity protection algorithm, and header compression parameters.
  • RLF layer parameters: These parameters include the scheduling algorithm and power control parameters.

The eNodeB sends the Full-config IE to the UE when the UE first attaches to the cell, or when the cell configuration changes. The UE uses the information in the Full-config IE to configure its radio and protocol layers.

Full-config IE is an important part of the RRC reconfiguration procedure. It allows the eNodeB to quickly and efficiently update the UE’s configuration parameters, ensuring that the UE can continue to operate correctly in the cell.
