Abstract: A narrowband network base station and a mobile station data transmission scheduling method thereof are provided. Within a control channel period, the narrowband network base station selects a first candidate unit which corresponds to a first shared channel initial subframe within a shared channel period while the first shared channel initial subframe is closest to an initial subframe of the shared channel period. The narrowband network base station determines a plurality of first data transmission units based on distances between the first shared channel initial subframe and different shared channel initial subframes. The narrowband network base station selects a second data transmission unit from the first data transmission units while the second data transmission unit corresponds to an under-transmission data amount of a first mobile station, and allocates the first candidate unit and the second data transmission unit to the first mobile station.

Abstract: A base station and a radio resource dynamic allocation method thereof for a Narrowband Internet of Thing (NB IoT) system are provided. The base station determines that a plurality of user equipments (UEs) are involved in radio resource scheduling and allocation according to scheduling information, and determines a received signal quality of each UE according to a feedback message received from each UE. Afterwards, according to the received signal quality of each UE, the base station performs a downlink control information (DCI) subframe repetition number evaluation and adjustment procedure to determine whether a DCI subframe repetition number of the each UE in a narrowband physical downlink control channel needs to be adjusted and adjust the DCI subframe repetition number which needs to be adjusted. After the DCI subframe repetition number evaluation and adjustment procedure, the base station executes the radio resource scheduling and allocation.

Abstract: A central controller and a resource allocation method thereof for use in a cellular network are provided. The cellular network includes a user equipment and the central controller. The central controller includes a transceiver and a processor. The transceiver receives a service request signal from the user equipment. The processor is electrically connected to the transceiver and is used to determine a requested service classification of the user equipment according to the service request signal, select a selected resource allocation strategy from a resource allocation strategy set according to the requested service classification, and allocate resources to the user equipment according to the selected resource allocation strategy. The central controller and the user equipment transmit data by the resource.
