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.
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 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.
