Transmitting and receiving devices for reliable reception of control messages

A transmitting device for a wireless communication system, the transmitting device comprising a processor and a memory coupled to the processor and having processor-executable instructions stored thereon, which when executed by the processor, cause the transmitting device to:

• replace bits of a bit field (fn) with padded bits to obtain control information with embedded padded bits;
• wherein the control information before replacing the bits of the bit field fn with padded bits comprises a plurality of information bit fields (f1, . . . , fn, . . . , fN),
• obtain a first cyclic redundancy check (CRC) word based on encoding the control information with embedded padded bits using a first CRC generator polynomial;
• append the first CRC word to the control information with the embedded padded bits:
• and obtain a second CRC word based on encoding the control information with the embedded padded bits together with the appended first CRC word using a second CRC generator polynomial;
• replace the embedded padded bits by the second CRC word to obtain another control information;
• form a control message based on the another control information;
• and
• transmit the control message to a receiving device.
