Medium Access Control (MAC) for LTE

This protocol is layer 2 of the LTE air interface (connecting an LTE UE with an eNodeB).

Protocol dependencies

  • MAC-LTE runs over the PHY layer

Example traffic

Wireshark

The MAC-LTE dissector is fully functional. However, at the moment there is only support for the DCT2000 file format.

MAC-LTE statistics can be viewed in a window (see Telephony | LTE MAC ...)

Preference Settings

  • Expect single RAR bodies. This controls whether or not a full MAC PDU will be present for an RA-RNTI, or just a single RAR body. Default is FALSE.
  • Warn if reserved bits are not 0. This controls whether or not expert info should be displayed if reserved bits are non-zero. Default is currently TRUE.

Example capture file

XXX - Add a simple example capture file to the SampleCaptures page and link from here (see below). Keep this file short, it's also a good idea to gzip it to make it even smaller, as Wireshark can open gzipped files automatically.

Display Filter

A complete list of MAC-LTE display filter fields can be found in the display filter reference

  • Show only the MAC-LTE based traffic:

     mac-lte 

Capture Filter

You cannot directly filter MAC-LTE protocol frames while capturing.

  • 3GPP TS 36.321 Evolved Universal Terrestrial Radio Access (E-UTRA); Medium Access Control (MAC) protocol specification
