Disclosed are a method for transmitting a reference signal, and a communication device. The method is executable by a terminal device or a network device, and comprises: determining at least one time domain resource unit for transmitting a reference signal; and transmitting the reference signal on the at least one time domain resource unit. Since the reference signal is transmitted on the at least one specific time domain resource unit rather than being transmitted by reusing a portion of subcarriers of a time domain resource unit for data transmission, a delay in transmission of the reference signal is reduced, thereby reducing a delay in data demodulation or CSI measurement performed on the basis of the reference signal, and reducing control signaling overhead for indication of a rate matching resource and complexity of performing rate matching.

Implementing a circuit design using time-division multiplexing (TDM) can include determining a net signature for each of a plurality of nets of a circuit design. For each net, the net signature specifies location information for a driver and one or more loads of the net. The plurality of nets having a same net signature can be grouped according to distance between drivers of the respective nets. One or more subgroups can be generated based on a TDM ratio for each group. For one or more of the subgroups, a TDM transmitter circuit is connected to a TDM receiver circuit through a selected interconnect, the drivers of the nets of the subgroup are connected to the TDM transmitter circuit, and loads of the nets of the subgroup are connected to the TDM receiver circuit.
