Abstract
An apparatus for feeding back channel state information includes: a receiver configured to receive a reporting configuration from a network device, wherein the reporting configuration comprises codebook indication information and feedback configuration information; processor circuitry configured to measure a channel state information reference signal to obtain channel state information, and process the channel state information according to the codebook indication information and the feedback configuration information to obtain a first channel state information; and a transmitter configured to feed back the first channel state information to the network device.
Claims20
An apparatus for feeding back channel state information, comprising:
- a receiver configured to receive a reporting configuration from a network device, wherein the reporting configuration comprises codebook indication information and feedback configuration information;
- processor circuitry configured to measure a channel state information reference signal to obtain channel state information, and process the channel state information according to the codebook indication information and the feedback configuration information to obtain a first channel state information;
- and
- a transmitter configured to feed back the first channel state information to the network device.
An apparatus for feeding back channel state information, comprising:
- a receiver configured to receive first reporting configuration from a network device, the first reporting configuration comprising feedback configuration information and similarity indication information for configuring a terminal equipment to report channel state information similarity;
- processor circuitry configured to measure channel state information reference signal to obtain channel state information, process the channel state information according to the feedback configuration information to obtain first channel state information, and calculate similarity information based on channel state information to which the feedback configuration information corresponds;
- and
- a transmitter configured to feed back the first channel state information and/or the similarity information to the network device.
An apparatus for feeding back channel state information, comprising:
- a receiver configured to receive similarity requirement information from a network device;
- processor circuitry configured to:
- estimate feedback configuration information used for channel state information reporting according to the similarity requirement information;
- measure a channel state information reference signal to obtain channel state information;
- and
- process the channel state information according to reporting configuration information and/or the feedback configuration information to obtain the first channel state information;
- and
- a transmitter configured to feed back the feedback configuration information to the network device;
- the receiver is further configured to receive the reporting configuration information of first channel state information transmitted by the network device, wherein the reporting configuration information is generated by the network device according to the feedback configuration information fed back by the terminal equipment;
- and
- the transmitter is configured to feed back the first channel state information to the network device.
