METHODS AND APPARATUSES FOR RECEIVING AND SENDING REFERENCE SIGNAL, USER EQUIPMENT, AND BASE STATION

摘要

Embodiments of the present invention relates to methods and apparatuses for receiving and sending a reference signal, a user equipment, and a base station. The method for receiving a reference signal comprises: receiving resource configuration information of a reference signal, the resource configuration information of the reference signal comprising information about an antenna port configuration and a reference signal subframe configuration, the antenna port configuration indicating an antenna port structure, and the reference signal subframe configuration indicating a reference signal subframe for sending a reference signal on one or more antenna port groups; and receiving the reference signal according to the resource configuration information of the reference signal. It can be seen that in the embodiments of the present invention, a UE measures a channel according to a reference signal obtained from a base station and feeds back signal quality or channel state information, so that a communications system can be self-adaptive to an antenna array structure and a configuration of more antenna ports; the present invention is used in cell selection or MCS selection and scheduling, thereby improving the throughput of a system.
