Decoder: 5G RRC ASN.1

5G RRC ASN.1 Hex Decoder

NR RRC messages are ASN.1 encoded and the same bytes can decode differently based on top-level ASN.1 interface/message wrapper. Choose the interface and message type first for contextual decoding.

About 5G RRC ASN.1

5G RRC carries radio-control signaling between UE and gNB for setup, reconfiguration, mobility, and release procedures. Decoding requires the correct ASN.1 wrapper (for example DL-DCCH or UL-CCCH) before field interpretation.

NR RRC messages are ASN.1 encoded and the same bytes can decode differently based on top-level ASN.1 interface/message wrapper. Choose the interface and message type first for contextual decoding.

5G RRC ASN.1 Header Structure

  • Select ASN.1 interface wrapper: DL/UL CCCH, DL/UL DCCH, BCCH, or PCCH.
  • Select RRC message type within the chosen interface.
  • Decode payload bytes under the selected top-level ASN.1 context.
