Transmitting node, a receiving node and methods therein for providing enhanced channel coding

A transmitting node for providing enhanced channel coding of a packet transmitted in a wireless communications network, wherein the transmitting node and a receiving node are configured to operate in the wireless communications network, and wherein the transmitting node comprises:

• transmitter circuitry;
• and
• processing circuitry configured to:
• apply, to payload data to be transmitted via the transmitter circuitry, an outer channel encoder resulting in a plurality of outer code bits;
• apply an inner channel encoder to the plurality of outer code bits;
• divide resulting code bits of the inner channel encoder into a first group of bits comprising one or more bits of a first type and one or more second groups of bits comprising one or more bits of a second type;
• generate a first set of Orthogonal Frequency-Division Multiplexing (OFDM) symbols carrying at least a part of the first group of bits, and one or more second sets of OFDM symbols carrying at least a part of the one or more second groups of bits;
• and
• transmit, to the receiving node, a packet comprising the first set of OFDM symbols followed by the one or more second sets of OFDM symbols, whereby an enhanced channel coding of the transmitted packet is provided.

A method, performed by a receiving node, for enabling enhanced channel coding of a packet transmitted in a wireless communications network, wherein a transmitting node and the receiving node are operating in the wireless communications network, and wherein the method comprises:

• receiving, from the transmitting node, parts of a packet, which packet comprises a first set of Orthogonal Frequency-Division Multiplexing (OFDM) symbols followed by one or more second sets of OFDM symbols, wherein the first set of OFDM symbols carries at least a part of a first group of bits comprising bits of a first type, and wherein the one or more second sets of OFDM symbols carry at least a part of one or more second groups of bits comprising bits of a second type;
• when payload data is decodable from received parts comprising the first set of OFDM symbols, decoding the payload data from the first set of OFDM symbols;
• when payload data is unsuccessfully decoded from received parts comprising the first set of OFDM symbols, decoding the payload data from the first set of OFDM symbols and the one or more second sets of OFDM symbols;
• and
• stopping receiving parts of the packet when the payload data is decoded.
