Decoder: 5G NR PDCP

5G NR PDCP Hex Decoder

PDCP in 5G NR sits above RLC and provides sequence numbering, ciphering/integrity context, and reordering support. Header decode helps validate bearer-plane packet flow and PDU type handling.

About 5G NR PDCP

5G NR PDCP headers indicate whether a PDU is data or control and carry sequence-related context used for ordering and loss handling. Quick decoding helps triage radio-bearer framing behavior.

PDCP in 5G NR sits above RLC and provides sequence numbering, ciphering/integrity context, and reordering support. Header decode helps validate bearer-plane packet flow and PDU type handling.

5G NR PDCP Header Structure

  • D/C bit: indicates data PDU (1) or control PDU (0).
  • Control PDU Type bits (for control PDUs): identifies control message class.
  • Sequence Number bits (for data PDUs): ordering context used for reordering/duplication handling.
  • Payload: ciphered/plain SDU bytes or control-specific content.
