Abstract: The present disclosure relates to a method for measuring and feeding back channel state information. In one example method, a user equipment (UE) receives a first channel state information report type configured by a base station and K channel state information-reference signal (CSI-RS) resources transmitted by the base station. The UE determines, according to the first channel state information report type, at least one of a rank indication (RI) and a beamforming indication (BI) on S subbands of a wideband on which the K CSI-RS resources are transmitted. The UE calculates a channel quality indicator (CQI) on the S subbands The UE reports the determined at least one of the RI and the BI, and the calculated CQI on a physical uplink control channel (PUCCH) by using a report.

Abstract: This application discloses a reference signal configuration method and apparatus. Before a network device sends reference signals aperiodically, the network device sends configuration information to a terminal device, where the configuration information is used to indicate a timeslot offset of one or more reference signal resource sets. Therefore, the network device can flexibly send reference signals in different timeslots, thereby reducing a quantity of times of reference signal triggering and measurement result reporting, and improving efficiency of a communications system.

Abstract: This application provides a channel state information (CSI) sending method, an apparatus, and a system. In this solution, a terminal device feeds back a first rank used for a common channel and a first precoding matrix indicator, and feeds back a second rank used for a traffic channel and a second precoding matrix indicator to a base station. The first precoding matrix indicator is used to indicate a first precoding matrix in a first precoding matrix set. The second precoding matrix indicator is used to indicate a second precoding matrix in a second precoding matrix set. The first precoding matrix set is different from the second precoding matrix set. Different precoding matrix sets are used on the common channel and the traffic channel, to obtain channel state information, thereby reducing bits required for feedback while satisfying a system requirement.
