Abstract
The present disclosure provides a CSI acquisition method. A network side device indicates a CSI feedback configuration group for aperiodic CSI feedback to a UE, and transmits DCI to the UE, the DCI configured to indicate the UE to perform the aperiodic feedback in accordance with an optimum CSI feedback configuration in the CSI feedback configuration group.
Claims21
A Channel State Information (CSI) acquisition method, comprising steps of:
- indicating, by a network side device, a CSI feedback configuration group for aperiodic CSI feedback to a User Equipment (UE);
- and
- transmitting, by the network side device, Downlink Control Information (DCI) to the UE, the DCI configured to indicate the UE to perform the aperiodic CSI feedback in accordance with an optimum CSI feedback configuration in the CSI feedback configuration group.
A Channel State Information (CSI) feedback method, comprising steps of:
- receiving, by a User Equipment (UE), a CSI feedback configuration group for aperiodic CSI feedback indicated by a network side device;
- and
- receiving, by the UE, Downlink Control Information (DCI) from the network side device, and performing the aperiodic CSI feedback in accordance with an optimum CSI feedback configuration in the CSI feedback configuration group.
16-30. (canceled)
A network side device, comprising:
- a processor;
- a memory connected to the processor through a bus interface and configured to store therein programs and data for an operation of the processor;
- and
- a transceiver configured to communicate with other devices over a transmission medium, wherein
- the processor is configured to call and execute the programs and data stored in the memory to:
- indicate a Channel State Information (CSI) feedback configuration group for aperiodic CSI feedback to a User Equipment (UE);
- and transmit Downlink Control Information (DCI) to the UE, the DCI configured to indicate the UE to perform the aperiodic CSI feedback in accordance with an optimum CSI feedback configuration in the CSI feedback configuration group.
A User Equipment (UE), comprising:
- a processor;
- a memory connected to the processor through a bus interface and configured to store therein programs and data for an operation of the processor;
- and
- a transceiver configured to communicate with other devices over a transmission medium, wherein
- the processor is configured to call and execute the programs and data stored in the memory to:
- receive a Channel State Information (CSI) feedback configuration group for aperiodic CSI feedback indicated by a network side device;
- and receive Downlink Control Information (DCI) from the network side device, and perform the aperiodic CSI feedback in accordance with an optimum CSI feedback configuration in the CSI feedback configuration group.
