Abstract: 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.

Abstract: A power amplifier, a radio remote unit (RRU), and a base station, where the power amplifier includes an envelope controller, a main power amplifier, and an auxiliary power amplifier. The main power amplifier and the auxiliary power amplifier both set an envelope voltage output by the envelope modulator as operating voltages, and because the operating voltages of the main power amplifier and the auxiliary power amplifier may be adjusted simultaneously, symmetry of the power amplifier is improved, and an efficiency loss occurring probability is low, thereby enhancing efficiency of the power amplifier.
