摘要： Embodiments of this application disclose a backup power supply method and a related device, to perform precise backup power supply control for services on different importance levels. The method in embodiments of this application includes: calculating a battery capacity of a battery based on historical power outage alarm information and historical power consumption information of a station in which the battery is located; if a power outage occurs in the station, calculating a state of charge of the battery based on actual power consumption and power outage duration of the station, and the battery capacity; and sending a current target energy saving level of the battery to the station if it is determined, based on the state of charge, that an energy saving level of the battery changes, so that the station uses a power saving policy corresponding to the target energy saving level, to reduce power consumption of the station.

摘要： Embodiments of the present invention disclose a method and a system for transmitting a communication signal, relates to the field of communications, and can improve receiving performance of a base station while enlarging coverage of the base station. The method of the present invention includes: receiving, by a baseband unit, main and diversity baseband uplink digital signals output by at least two radio remote units, where the at least two radio remote units are radio remote units to which different site addresses in a same cell correspond, one cell includes at least two radio remote units, and each radio remote unit corresponds to a different site address and at least one pair of main and diversity antennas, receives a radio signal through a corresponding main and diversity antenna, and outputs a main and diversity baseband uplink digital signal; performing combination calculation on the main and diversity baseband uplink digital signals output by the at least two radio remote units to obtain a combined baseband uplink digital signal; and performing baseband processing on the combined baseband uplink digital signal. The embodiments of the present invention are mainly applied to the process of mobile communication by a user on a high-speed railway.
