Network node and method performed therein for handling communication

A network node for handling a received signal in a communication network, the network node configured to:

• distribute a first number of inputs of a demodulated signal to a first processing core of at least two processing cores and a second number of inputs of the demodulated signal to a second processing core of the at least two processing cores;
• and
• decode the first number of inputs of the demodulated signal by a first message passing within the first processing core, and decode the second number of inputs of the demodulated signal by a second message passing within the second processing core, and to further decode the demodulated signal by performing a third message passing between the different processing cores over a bus that is performed according to a set schedule, the set schedule being based on one or more of a type of code, a length of code and a performance of the bus.

A non-transitory computer-readable storage medium, having stored there on a computer program comprising instructions which, when executed on at least one processor, cause the at least one processor to carry out a method performed by a network node for handling a received signal in a communication network, the method comprising:

• distributing a first number of inputs of a demodulated signal to a first processing core of at least two processing cores and a second number of inputs of the demodulated signal to a second processing core of the at least two processing cores;
• and
• decoding the first number of inputs of the demodulated signal by a first message passing within the first processing core, and decoding the second number of inputs of the demodulated signal by a second message passing within the second processing core, and further decoding the demodulated signal by performing a third message passing between the different processing cores over a bus that is performed according to a set schedule, the set schedule being based on one or more of a type of code, a length of code and a performance of the bus.
