Energy saving method and apparatus, and computer-readable storage medium

An energy saving apparatus, comprising:

• at least one processor;
• and
• a memory coupled to the at least one processor and storing executable instructions for execution by the at least one processor to:
• determine n radio remote units (RRUs) in m RRUs, wherein a sum of first downlink reference signal received powers (RSRPs) of a same terminal, corresponding to the n RRUs, is greater than or equal to a first preset value, wherein one RRU corresponds to first downlink RSRPs of a plurality of terminals, wherein a first downlink RSRP of one terminal corresponding to one RRU is a received power that is estimated by the processor, that is measured by the terminal, and that is of a reference signal (RS) from the RRU at a corresponding first RS transmit power, wherein a first RS transmit power corresponding to one RRU is an RS transmit power obtained after power boosting is performed on a second RS transmit power corresponding to the RRU, wherein second RS transmit powers corresponding to the m RRUs are all preconfigured, wherein the first preset value is a level value to be reached when the plurality of terminals perform a downlink service, and wherein n is an integer greater than 0 and less than m;
• and
• in response to determining the n RRUs in the m RRUs:
• turn off an RRU that is in the m RRUs and that is different from the n RRUs;
• and
• boost a second RS transmit power corresponding to each of the n RRUs to a corresponding first RS transmit power, and enabling each of the n RRUs to send an RS at the corresponding first RS transmit power.

A non-transitory computer-readable storage medium, comprising an instruction for execution by a computer to:

• determine n radio remote units (RRUs) in m RRUs, wherein a sum of first downlink reference signal received powers (RSRPs) of a same terminal, corresponding to the n RRUs, is greater than or equal to a first preset value, wherein one RRU corresponds to first downlink RSRPs of a plurality of terminals, wherein a first downlink RSRP, of one terminal, corresponding to one RRU is a received power that is estimated by the computer, that is measured by the terminal, and that is of a reference signal (RS) from the RRU at a corresponding first RS transmit power, wherein a first RS transmit power corresponding to one RRU is an RS transmit power obtained after power boosting is performed on a second RS transmit power corresponding to the RRU, wherein second RS transmit powers corresponding to the m RRUs are all preconfigured, wherein the first preset value is a level value to be reached when the plurality of terminals perform a downlink service, and wherein n is an integer greater than 0 and less than m;
• and
• in response to determining the n RRUs in the m RRUs:
• turn off an RRU that is in the m RRUs and that is different from the n RRUs;
• and
• boost a second RS transmit power corresponding to each of the n RRUs to a corresponding first RS transmit power, and enabling each of the n RRUs to send an RS at the corresponding first RS transmit power.
