This TS specifies the E-UTRA MAC protocol. E-UTRA defines two MAC entities; one in the UE and one in the E-UTRAN. These MAC entities handle the following transport channels:
  • Broadcast Channel (BCH);
  • Downlink Shared Channel(s) (DL-SCH);
  • Paging Channel (PCH);
  • Uplink Shared Channel(s) (UL-SCH);
  • Random Access Channel(s) (RACH);
  • Multicast Channel(s) (MCH).
The exact functions performed by the MAC entities are different in the UE from those performed in the E-UTRAN. The Relay Node includes both MAC entities; one for communication with UEs and one for communication with the E-UTRAN.
