Resource configuration for NB-IoT

Embodiments of the present disclosure relate to the resource configuration for Narrow Band Internet of Thing (NB-IoT). A method of resource configuration for NB-IoT includes determining, at a network device, whether a configured Uplink Resource (PUR) for transmission from a terminal device to the network device is to be adjusted; in response to determining that the PUR is to be adjusted, determining a set of resources to be allocated for further transmission from the terminal device to the network device based on a Transport Block Size (TBS) associated with the further transmission; generating reconfiguration information of the PUR based on the set of the resources; and transmitting the reconfiguration information to the terminal device. In this way, the resource configuration may be determined and adjusted more efficiently and flexibility compared to the conventional way.
