+### 6.1.2 MAC PDU (DL-SCH and UL-SCH except transparent MAC and Random Access Responses)
+
+A MAC PDU consists of one or more MAC subPDUs. Each MAC subPDU consists of one of the following:
+
+- A MAC subheader only (including padding);
+- A MAC subheader and a MAC SDU;
+- A MAC subheader and a MAC CE;
+- A MAC subheader and padding.
+
+The MAC SDUs are of variable sizes.
+
+Each MAC subheader corresponds to either a MAC SDU, a MAC CE, or padding.
+
+A MAC subheader except for fixed sized MAC CE, padding, and a MAC SDU containing UL CCCH consists of the header fields R/F/LCID/(eLCID)/L. A MAC subheader for fixed sized MAC CE and padding consists of the header fields R/LCID/(eLCID). A MAC subheader for a MAC SDU containing UL CCCH consists of the header fields (LX)/R/LCID.

+- For whatrever reason mermaid cuts the caption
+- No way to add multiple variants of the same figure, need to add multiple figures instead (shouldn't be a big deal)
