Abstract: The present disclosure relates to symbol processing methods. One example method, applied to a radio unit, includes detecting numeric values of first N sampling points on each symbol of a target subframe, where symbol periodicities of symbols of the target subframe are the same, and N is a positive integer greater than 0, in response to detecting that numeric values of first N sampling points on a first symbol are all 0, determining that no service data is sent on the first symbol, and shutting down a power amplifier within a symbol periodicity of the first symbol.

Abstract: A power consumption control method, baseband unit (BBU), radio unit (RU), system, and a storage medium are provided. The method includes: A BBU detects load of a to-be-detected cell. If the load of the to-be-detected cell is less than a first threshold, the BBU determines a first allowable power of a carrier corresponding to the to-be-detected cell. The BBU sends the first allowable power to an RU, to indicate to the RU to adjust, based on the first allowable power, a bias voltage of a power amplifier (PA) corresponding to the carrier corresponding to the to-be-detected cell. The first allowable power is less than a maximum allowable power of the carrier corresponding to the to-be-detected cell.

Abstract: This application provides an example load threshold determining method and apparatus. The method includes obtaining a plurality of preselected load thresholds of a cell. The method also includes obtaining an evaluation value corresponding to each preselected load threshold in a first periodicity, where each evaluation value is used to evaluate key performance indicator (KPI) information and energy saving information of the cell. The method further includes determining a target load threshold of the cell in a second periodicity based on all evaluation values, where the target load threshold is a load threshold in the plurality of preselected load thresholds, and where the second periodicity is a next periodicity of the first periodicity.

Abstract: A power outage processing method: receiving, by a controller in a base station, notification information sent by a first power source, where the notification information is used to indicate that a power outage has occurred on the first power source; the base station includes M radio units, and the M radio units are supplied with power by N power sources, where each power source is connected to at least one radio unit; and the first power source is one of the N power sources, and the N power sources are all supplied with power by using a power grid, determining, by the controller based on connection relationships between the N power sources and the M radio units, a radio unit connected to the first power source; and instructing, by the controller, all or some of radio units connected to the first power source to reduce power consumption.
