WebFeb 2, 2024 · There are three types of channels: Logical Channels: Offered by MAC to RLC. Control channels carry CP packets. Traffic channels carry UP packets. Each logical channel maps to an RLC channel coming from RLC layer. Transport Channels: Offered by PHY to MAC. MAC layer multiplexes one or more logical channels to a transport channel.

WebLTE utilizes incremental-redundancy HARQ with a 1/3 turbo encoder used for FEC. The transport block CRC is used to detect errors. The receiver only receives different punctured versions of the same turbo-encoded data; each of these retransmissions is self-decodable. Thus, it falls into the category of a type III HARQ described earlier.
