The LTE transport channels vary between the uplink and the downlink as each has different requirements and operates in a different manner. Physical layer transport channels offer information transfer to medium access control (MAC) and higher layers.

Downlink:
Broadcast Channel (BCH)
: The LTE transport channel maps to Broadcast Control Channel (BCCH)
Downlink Shared Channel (DL-SCH) : This transport channel is the main channel for downlink data transfer. It is used by many logical channels.
Paging Channel (PCH) : To convey the PCCH
Multicast Channel (MCH) : This transport channel is used to transmit MCCH information to set up multicast transmissions.

Uplink:
Uplink Shared Channel (UL-SCH)
: This transport channel is the main channel for uplink data transfer. It is used by many logical channels.
Random Access Channel (RACH) : This is used for random access requirements.

  2. Downlink shared channel (DL-SCH)
  3. Paging Channel (PCH)
  4. Multicast Channel (MCH)

Uplink Direction:
