A network for handling parameter configurations comprises a processing means to execute instructions. The instructions comprise determining a subset of parameter configurations; transmitting information of the subset of parameter configurations to a communication device via a higher layer signaling; selecting at least one parameter configuration from the subset of parameter configurations, wherein the at least one parameter configuration corresponds to at least one communication device, respectively; transmitting information of the at least one parameter configuration to the communication device via a physical layer signaling; transmitting a signal to the communication device via a resource according to a transmission scheme and a parameter configuration of the communication device; and transmitting at least one signal to the at least one communication device via the resource according to the transmission scheme and the at least one parameter configuration.
