Patent ID: 8799740

Claim:
A method for a transmitter to transmit a transport block (TB) to a receiver, the method comprising: attaching a first type CRC (cyclic redundancy check) to the TB; segmenting the first type CRC attached-TB into a plurality of code blocks (CBs); attaching each of a plurality of second type CRCs to a corresponding one of the plurality of CBs such that one of the plurality of CBs includes the first type CRC and the second type CRC, and the rest of the plurality of CBs include the second type CRC, wherein the first type CRC and the second type CRC are generated by using different types CRC generating polynomials, wherein both the first type CRC and the second type CRC have a 24-bit length, wherein one of the different types of CRC generation polynomials is a first CRC polynomial expressed as: g ( x )= x 24 +x 23 +x 6 +x 5 +x+ 1, and wherein another one of the different types of CRC generation polynomials comprises a second CRC polynomial having a same order as the first CRC polynomial, the second CRC polynomial being different from the first CRC polynomial; channel coding the plurality of CBs; and transmitting the TB to the receiver by using the channel coded-plurality of CBs.
