Abstract
Official abstract text for this publication.
Examples of user equipments (UEs) are described. A UE includes receiving circuitry configured to receive first information to configure one or more channel state information-reference signals (CSI-RS) for tracking and second information to configure time domain correlation related information. The UE also includes transmitting circuitry configured to transmit a channel state information (CSI) report including the time domain correlation related information. A first parameter trs-Info is included in the first information. A second parameter reportQuantity is not set to ‘none’. The time domain correlation related information is measured by the one or more CSI-RS for tracking.
First claim
Opening claim text (preview).
The invention claimed is: 1. A user equipment (UE) comprising: receiving circuitry configured to receive first information to configure one or more non-zero power channel state information reference signal (CSI-RS) resources and second information to configure CSI reporting, measurement circuitry configured to measure time domain correlation related information based on the second information, and transmitting circuitry configured to transmit a channel state information (CSI) report including the time domain correlation related information based on the second information, wherein: the second information is associated with the first information, the first information includes a first parameter trs-Info, the first parameter trs-Info indicates the one or more CSI-RS resources for tracking in the time and frequency domain, the second information includes a second parameter reportQuantity indicating a kind of CSI is set to ‘TDCI’, and the ‘TDCI’ indicates time domain correlation related information. 2. A base station comprising: transmitting circuitry configured to transmit first information to configure one or more non-zero power channel state information reference signal (CSI-RS) resources and second information to configure CSI reporting, and receiving circuitry configured to receive a channel state information (CSI) report including the time domain correlation related information based on the second information, wherein: the second information is associated with the first information, the first information includes a first parameter trs-Info, the first parameter trs-Info indicates the one or more CSI-RS resources for tracking in the time and frequency domain, the second information includes a second parameter reportQuantity indicating a kind of CSI is set to ‘TDCI’, and the ‘TDCI’ indicates time domain correlation related information. 3. A communication method of a user equipment (UE) comprising: receiving first information to configure one or more non-zero power channel state information reference signal (CSI-RS) resources and second information to configure CSI reporting, measuring time domain correlation related information based on the second information, and transmitting a channel state information (CSI) report including the time domain correlation related information based on the second information, wherein: the second information is associated with the first information, the first information includes a first parameter trs-Info, the first parameter trs-Info indicates the one or more CSI-RS resources for tracking in the time and frequency domain, the second information includes a second parameter reportQuantity indicating a kind of CSI is set to ‘TDCI’, and the ‘TDCI’ indicates time domain correlation related information.
