NR Node Statistics

Since R2024a

This topic page presents various statistics captured at the application layer (APP), radio link control (RLC) layer, medium access control (MAC) layer, and physical layer (PHY) layer of a new radio (NR) node.

gNB Node Statistics

The output structure of the statistics function of an nrGNB object contains these fields.

FieldValuesDescription
IDpositive integerID of the gNB node.
Namestring scalar, character vectorName of the gNB node.
Appstructure

Application layer statistics, returned as a structure containing these fields.

  • TransmittedPackets — Total number of packets transmitted to the radio link control (RLC) layer.

  • TransmittedBytes — Total number of bytes transmitted to the RLC layer.

  • ReceivedPackets — Total number of packets received from the RLC layer.

  • ReceivedBytes — Total number of bytes received from the RLC layer.

If you call the statistics function using the "all" argument, the App structure also contains a field, Destinations. The Destinations field is an array of structures of size 1-by-N, where N is the number of connected user equipment (UE) nodes. Each structure element corresponds to a connected UE, and contains these fields.

  • UEID — ID of the UE node.

  • UEName — Name of the UE node.

  • RNTI — Radio network temporary identifier of the UE node.

  • TransmittedPackets— Total number of packets transmitted to the radio link control (RLC) layer.

  • DroppedPackets — Total number of received packets dropped because of reassembly failure.

  • DroppedBytes — Total number of received bytes dropped because of reassembly failure.

If you call the statistics function using the "all" argument, the RLC structure also contains a field, Destinations. The Destinations field is an array of structures of size 1-by-N, where N is the number of connected user equipment (UE) nodes.

MACstructure

MAC layer statistics, returned as a structure containing these fields.

  • TransmittedPackets — Total number of packets transmitted to the physical (PHY) layer. This only corresponds to new transmissions assuming that the MAC layer does not send the packet again to the PHY layer for retransmissions. Packets get buffered at the PHY layer. The MAC layer only sends the requests for retransmission to the PHY layer.

  • TransmittedBytes — Total number of bytes transmitted to the PHY layer.

  • ReceivedPackets — Total number of packets received from the PHY layer.

  • ReceivedBytes — Total number of bytes received from the PHY layer.

  • Retransmissions — Total number of retransmissions requests sent to the PHY layer.

  • RetransmissionBytes — Total number of MAC bytes that correspond to the retransmissions.

If you call the statistics function using the "all" argument, the MAC structure also contains a field, Destinations. The Destinations field is an array of structures of size 1-by-N, where N is the number of connected user equipment (UE) nodes. Each structure element corresponds to a connected UE, and contains these fields.

  • UEID— ID of the UE node.

  • UEName— Name of the UE node.

  • RNTI— Radio network temporary identifier of the UE node.

  • TransmittedPackets— Total number of packets transmitted to the physical (PHY) layer.

PHYstructure

PHY layer statistics, returned as a structure containing these fields.

  • TransmittedPackets — Total number of packets transmitted.

If you call the statistics function using the "all" argument, the PHY structure also contains a field, Destinations. The Destinations field is an array of structures of size 1-by-N, where N is the number of connected user equipment (UE) nodes. Each structure element corresponds to a connected UE node, and contains these fields.

  • UEID — ID of the UE node.

  • UEName — Name of the UE node.

  • RNTI — Radio network temporary identifier of the UE node.

  • TransmittedPackets — Total number of packets transmitted.
