About LTE MAC

LTE MAC PDUs are organized as a sequence of MAC subheaders followed by MAC SDUs or control elements. Subheader interpretation is the key step for identifying each payload block and its length.

LTE MAC multiplexes logical channels and control elements over the radio link. Subheader-level decoding helps inspect scheduling, channel usage, and MAC framing behavior.

LTE MAC Header Structure

R + E + LCID fields in each subheader: reserved bit, chaining indicator, and logical/control channel ID.
Length field (when present): indicates MAC SDU or variable-size control element length.
E bit behavior: E=1 means another subheader follows, E=0 means this is the final subheader.
Payload ordering: all subheaders first, then corresponding SDU/CE payload sections.

Why Decode LTE MAC Packets

Decode LTE MAC subheader fields from hex including extension bit, LCID, and payload length indicator.
