Abstract
The present embodiments relate to the method and device, user equipment and the base stations that send and receive reference signal.Wherein, the method for receiving reference signal includes：Receive reference signal resource configuration information, wherein reference signal resource configuration information includes the information of antenna port configuration and reference signal sub-frame configuration, antenna port configuration instruction antenna port structure, the instruction of reference signal sub-frame configuration send the reference signal subframe of reference signal in one or more antenna port groups；According to reference signal resource configuration information, reference signal is received.It can be seen that, in the embodiment of the present invention, UE measures channel and feedback signal quality or channel state information based on the reference signal obtained from base station, then communication system adaptive antenna array structure and more antenna port numbers is enable to configure, for cell selection or MCS selections and scheduling, and then improve the handling capacity of system.
