// Interface for the Medium Access Control (MAC) layer of the LTE Stack.
//
// The LteMac module interface provides the definition for the MAC layer in the LTE protocol stack.
// The MAC layer sends and receives MAC Service Data Units (SDUs) from the Radio Link Control (RLC)
// layer and sends and receives MAC Protocol Data Units (PDUs) to the physical layer. The MAC layer
// is responsible for scheduling MAC PDUs from different logical connections into the available
// bandwidth in both uplink and downlink directions.
// Dynamic allocation of Resource Blocks (RBs) is carried out by the eNodeB on a Transmission Time
// Interval (TTI) basis, which occurs every 1 millisecond, and is assisted by User Equipment's Channel
// Status Information (CSI) to perform link adaptation, as well as Buffer Status Reports (BSRs, for
// uplink connections only). A Random Access procedure (RACH) is used by unscheduled UEs to
// request uplink resources. Scheduling policies are defined separately by dedicated C++ classes.
// The MAC layer also provides Hybrid Automatic Repeat reQuest (H-ARQ) functionalities, enabling
// feedback reporting and retransmission of incorrectly received MAC PDUs.
// Semi-persistent Scheduling (SPS), power control, and Discontinuous Reception (DRX) are not
// implemented.
