CRC (Cyclic
Redundancy Check) is an error-detecting mechanism used in LTE to
ensure data integrity at the Physical
Layer (PHY). It is a checksum-based method where extra bits (CRC bits) are
appended to data blocks to detect errors during transmission.
- Purpose: Detect transmission errors in transport blocks and control channels.
- Layer: PHY (Physical Layer)
- Bit Length: 16-bit
or 24-bit CRC depending on the channel.
CRC
is used in three
main places in LTE.
