LTE channels are used to transport the different types of data across the LTE radio interface, for this purpose many different channels are used.

There are three types of LTE channels

  1. Logical channel – LTE-RLC layer passes data to the LTE-MAC layer as logical channels. These channels provide services for the LTE –MAC layer within the LTE protocol structure.
  2. Transport Channel – The LTE-MAC layer formats and send the logical channel data as transport channels. These channels offer information transfer to LTE – MAC and higher layers.
  3. Physical channel – The LTE-PHY layer encodes the transport channel data to physical channels. These are transmission channels that carry user data and control messages.
