Abstract: Embodiments of this application provide a power control method, a communication apparatus, and a communication system. The method includes: determining whether a first condition is met, where the first condition includes that a time-frequency resource for sending a first beam and a time-frequency resource for sending a second beam overlap, a ratio of interference of the first beam to the second beam to noise floor of a receiver is greater than a first threshold, and a ratio of interference of the second beam to the first beam to the noise floor of the receiver is greater than the first threshold; and reducing transmit power of the first beam and transmit power of the second beam when the first condition is met.

Abstract: An input matching circuit and a related apparatus are provided. The input matching circuit includes an inductive branch, a first resistor, and a field-effect transistor, the inductive branch includes one or more inductors and a second resistor, a first end of the first resistor is connected to a signal input end, and a second end of the first resistor is grounded. The signal input end is configured to provide a signal input for the input matching circuit, an input end of the inductive branch is connected to the signal input end, and an output end of the inductive branch is grounded. An inductance value of an equivalent inductor of the inductive branch between the signal input end and the ground varies with adjustment of a frequency of a signal input by the signal input end.

Abstract: Embodiments of this application disclose a cell measurement method and a related apparatus. The method includes: A first access network device sends first measurement control information to a terminal device through a first serving cell. The first measurement control information indicates the terminal device to measure quality of a downlink reference signal of a virtual cell. A center frequency of a downlink reference signal of the first serving cell is the same as a center frequency of the downlink reference signal of the virtual cell, a frequency range of the virtual cell is included in a frequency range of a second serving cell, and the frequency range of the second serving cell overlaps with a frequency range of the first serving cell. The first access network device receives a first measurement report from the terminal device, where the first measurement report indicates the quality of the downlink reference signal of the virtual cell. The first access network device migrates the terminal device to a third serving cell when the quality of the downlink reference signal of the virtual cell is higher than quality of the downlink reference signal of the first serving cell. Near-far interference to the terminal device can be avoided by using the method.
