摘要
說(shuō)明書(shū)
In one embodiment, when M≥2, the target CSI-IM resource is the first-type CSI-IM resource, and the terminal device measures interference information on the target CSI-IM resource and all or a part of CSI-RS resources that are indicated by downlink control information in the M pieces of downlink control information except the first downlink control information, determines the channel state information based on the obtained interference information, and reports the channel state information. In this case, interference information obtained by the terminal device through measurement on the target CSI-IM resource is interference from another non-serving base station, and interference information obtained by the terminal device through measurement on all or a part of CSI-RS resources that are indicated by downlink control information other than the first downlink control information is inter-stream interference from another serving base station.
In one embodiment, when M≥2, and the target CSI-IM resource is the first-type CSI-IM resource, the terminal device measures interference information on the target CSI-IM resource and all or a part of CSI-RS resources that are indicated by downlink control information in the M pieces of downlink control information except the first downlink control information, determines the channel state information based on the obtained interference information, and reports the channel state information; and/or
when M≥2 and the target CSI-IM resource is the second-type CSI-IM resource, the terminal device measures interference information on the target CSI-IM resource, determines the channel state information based on the obtained interference information, and reports the channel state information.
