    摘要: Methods, systems, and devices for reducing channel state information feedback channel overhead by compressing coefficients of precoding vectors and reporting a subset of the compressed coefficients based on several parameters including network-signaled parameters. Some embodiments may be used in wireless communication embodiments in which channel state information from many layers and many frequency domain units need to be reported.

    摘要: The present invention provides an information processing method, comprising: generating signaling comprising configuration information of channel state information process (CSI process); and sending the signaling comprising the configuration information of the CSI process. The present invention resolves the problem in the related art of being unable to use one CSI-RS resource overhead to meet the transmission requirements of multiple CSI-RSs having different port numbers, thereby achieving the technical effect of reducing resource overheads. The present invention also provides an information processing device and a storage medium.

    摘要: Provided are CSI feedback and receiving methods, apparatuses, a device, and a storage medium. The method includes: a terminal determines PMI, the PMI includes at least one of: first base vector information, second base vector information, second coefficient amplitude information or phase information; for one transmission layer, a frequency domain resource in one preset frequency domain unit corresponds to one precoding vector, the precoding vector is a linear combination of first base vectors, and weighting coefficients used in the linear combination of the first base vectors are first coefficients; on multiple frequency domain units contained in a CSI feedback band, a vector composed of first coefficients corresponding to a same first base vector is a linear combination of second base vectors, and weighting coefficients used in the linear combination of the second base vectors are second coefficients; and the terminal feeds back CSI containing the PMI to a base station.

    摘要: Disclosed are a method for receiving a channel state information-reference signal, a processor, a terminal and a storage medium. The method includes that: a terminal receives information of the CSI-RS; the terminal receives the CSI-RS; and measures the CSI-RS to obtain CSI, and feeds back the CSI to the base station; and the terminal receives the information of the components notified by the base station includes at least one of the following: receiving a position of an earliest OFDM symbol of the components on the time domain positions and a position of a lowest-frequency subcarrier of the components on the frequency domain positions; receiving, a position of a latest OFDM symbol of the components and a position of a highest-frequency subcarrier of the components; or receiving a position of a latest OFDM symbol of the components and a position of a lowest-frequency subcarrier of the components.
