Wireless communication device and method

Abstract

A wireless communication device and method used in a base station side and a user equipment side. The wireless communication device used in the base station includes one or more processors configured to respectively configure, based on an antenna configuration of a base station and on a plurality of spatial dimensions, a downlink reference signal of the base station, and generate a control message comprising an indication indicating that the base station respectively transmits, on the plurality of spatial dimensions, the downlink reference signal, so as to be used in a user equipment served by the base station.

1 . An apparatus for wireless communications, comprising:
 one or more processors, configured to:
 configure, based on an antenna. configuration of a base station, downlink reference signals of the base station in a plurality of spatial dimensions respectively; and 
 generate a control message containing an indication that the base station transmits the downlink reference signals in the plurality of spatial dimensions respectively, for use by a communication device served by the base station, wherein 
 the control message indicates at least an antenna port set arranged at the base station to transmit the downlink reference signals, and 
 the control message indicates a plurality of transmitting time corresponding to each of the downlink reference signal in respective spatial dimensions. 
   
     
     
         2 . An apparatus for wireless communications, comprising:
 one or more processors, configured to   determine, based on a control message from a base station, that the base station transmits downlink reference signals in a plurality of spatial dimensions respectively, wherein   the control message indicates at least an antenna port set arranged at the base station to transmit the downlink reference signals, and   the control message indicates a plurality of transmitting time corresponding to each of the downlink reference signal in respective spatial dimensions;   measure, in response to a measurement indication from the base station, the downlink reference signals in respective spatial dimensions and generate measurement feedback information for the downlink reference signals;   the one or more processors is further configured to determine a spatial dimension of an individual downlink reference signal based on the transmitting time of the individual downlink reference signal.   
     
     
         3 . An apparatus for wireless communications, comprising:
 configuring, based on an antenna configuration of a base station, downlink reference signals of the base station in a plurality of spatial dimensions respectively; and   generating a control message containing an indication that the base station transmits the downlink reference signals in the plurality of spatial dimensions respectively, for use by a communication device served by the base station, wherein   the control message indicates at least an antenna port set arranged at the base station to transmit the downlink reference signals, and   the control message indicates a plurality of transmitting time corresponding to each of the downlink reference signal in respective spatial dimensions
