Abstract: A wireless communication device and a wireless communication method. A wireless communication device for use in a base station side includes one or more processors. The processor is configured to obtain a distribution state of a user equipment, and determine to use a channel state information-reference signal (CSI-RS) mechanism based on the distribution state of the user equipment. In addition, the processor is further configured to generate indication information, the indication information being used for indicating to the user equipment the CSI-RS to be used. Besides, the processor is further configured to control to send the CSI-RS to the user equipment according to the CSI-RS mechanism.

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.
