摘要： An embodiment method, by a user equipment (UE), includes performing a channel measurement (CM) on a first subset of a set of non-zero-power (NZP) CSI reference signal (CSI-RS) resources and an interference measurement (IM) on at least a second subset of the set of NZP CSI-RS resources. The second subset includes one or more NZP CSI-RS ports. The IM is performed according to assumptions: each NZP CSI-RS port in the second subset corresponds to an interference transmission layer, the IM being in accordance with a set of energy per resource element ratios each associated with one NZP CSI-RS resource in the second subset; and other interference not associated with the interference transmission layers is on the first and second subsets. The method includes generating a channel state information (CSI) report based on the CM and IM and transmitting the CSI report to a network.

摘要： Embodiments of this application provide an SRS sending method, an SRS receiving method, and a device. A manner of determining an antenna used to send an SRS is provided. In addition, a case in which one subframe includes a plurality of symbols is considered by using a quantity of first time units that are used by a terminal device to send an SRS in one uplink subframe and a case in which one antenna is enabled to implement continuous sending as much as possible is also considered by using a quantity of first time units that are consecutively used to send the SRS in one subframe by using a same antenna. Therefore, it may be learned that, in the technical solutions provided in the embodiments of this application, the manner of determining an antenna used to send an SRS is provided, and a same antenna can be enabled to implement continuous sending in one subframe as much as possible, thereby minimizing an antenna switching process.
