Abstract: The embodiments provide a bandwidth scheduling method and an apparatus to resolve a problem in the prior art that a transmission delay is relatively large and user experience is relatively poor when a baseband unit and a radio remote unit are networked by using a passive optical network. The method includes: allocating, by a baseband unit, radio resources used for data transmission between N first radio frequency units and a terminal to the N first radio frequency units connected to the baseband unit, where N is an integer greater than 0; and then allocating, by the baseband unit based on the radio resources of the N first radio frequency units, bandwidth resources used for data transmission between the baseband unit and the N first radio frequency units to the N first radio frequency units.

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.
