More Information
Summary:This application discloses a channel state information feedback method and apparatus, a medium, and a program product. A terminal obtains a long-period reporting amount of a precoding matrix indicator (PMI) in channel state information. N1 characteristic subspace beams are represented by a linear combination of M1 DFT base vectors in a first group of DFT base vectors, and N2 characteristic subspace beams are represented by a linear combination of M2 DFT base vectors in a second group of DFT base vectors. The long-period reporting amount includes indication information of the M1 DFT base vectors, indication information of the M2 DFT base vectors, a linear combination coefficient of the M1 DFT base vectors, and a linear combination coefficient of the M2 DFT base vectors. The terminal sends the long-period reporting amount of the PMI to an access network device.
