The invention provides base station side and user device side devices and methods for wireless communication. The base station side device for wireless communication includes a sequence generation unit which is configured to generate a reference signal sequence, and a resource mapping unit which is configured to determine a reference signal pattern formed by the mapping relationship between the antenna ports and the resource unit of the physical transmission resource according to the number of antenna ports for transmitting the reference signals and to map the reference signals to the resource unit for transmission based on the reference signal pattern, wherein the reference signal pattern includes code division multiplexing of the resource unit between the antenna ports in the frequency domain.
