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.

WebFeb 9, 2024 · Hybrid Automatic Repeat Request (HARQ) in Wireless Communications Systems and Standards: A Contemporary Survey Automatic repeat request (ARQ) schemes, and in particular hybrid-ARQ (HARQ) schemes, which jointly adopt forward error correction (FEC) and ARQ, are essential to provide reliable data transmission in wireless … WebHARQ Process in LTE LTE utilizes IR HARQ with a 1/3 turbo encoder used for FEC. The Transport Block (TB) CRC is used to detect errors. The receiver only receives different punctured versions of the same turbo-encoded data; each of these retransmissions are self decodable. Thus, it falls into category of a type III Hybrid ARQ.
