Abstract
A device used at a wireless communication base station side and a user equipment side, and a method. The device used at a wireless communication base station side includes: a sequence generation unit configured to generate a reference signal sequence; and a resource mapping unit configured to determine a reference signal pattern composed of a mapping relationship between an antenna port and a resource element of a physical transmission resource according to the number of antenna ports for sending reference signals, and mapping the reference signal sequence to the resource unit based on the reference signal pattern for transmission, wherein the reference signal pattern includes code division multiplexing conducted on the resource unit in a frequency domain between antenna ports.
