Method and apparatus for cell initial access and paging in wireless cellular communication system

A transmission node in a communication system, the transmission node comprising:

• a transceiver;
• and
• a processor coupled with the transceiver and configured to:
• obtain a transport block (TB) and a cyclic redundancy check (CRC) for the TB;
• obtain a plurality of code blocks based on segmenting a plurality of bits including the TB and the CRC for the TB;
• identify a plurality of code block indexes for the plurality of code blocks;
• obtain a signal to be transmitted based on the plurality of code blocks and the plurality of code block indexes, wherein the signal includes the plurality of code blocks and each of the plurality of code blocks is attached with information associated with a corresponding code block index among the plurality of code block indexes;
• and
• transmit the signal to a reception node.

A method performed by a reception node in a communication system, the method comprising:

• receiving a signal from a transmission node;
• obtaining, based on the signal, a plurality of code blocks and a plurality of code block indexes for the plurality of code blocks, wherein the signal includes the plurality of code blocks and each of the plurality of code blocks is attached with information associated with a corresponding code block index among the plurality of code block indexes;
• obtaining a plurality of bits including a transport block (TB) and a cyclic redundancy check (CRC) for the TB based on the plurality of code blocks, wherein an order of the plurality of code blocks is identified by the plurality of code block indexes;
• and
• determining whether the TB is successfully received based on the CRC.
