Abstract

Embodiments of the present disclosure provide a method for communication of spiking data on radio resources. The method is performed by a neuromorphic transmitter node. The method comprises obtaining the spiking data representing one or more spikes generated by a neuromorphic application. Each spike is associated with an identity of a neuron emitting the spike. The method further comprises mapping the spiking data to the radio resources. The spiking data is mapped to one or more radio resource elements based on one or more of: the identity of the neuron, transmission properties of the one or more spikes and availability of the radio resources. Corresponding neuromorphic transmitter node, neuromorphic receiver node and computer program products are also disclosed.
