1. A beamforming-based communication method performed by
a processor,
a memory is coupled to the processor, and the memory comprises instructions that, when executed by the processor, cause the processor to perform operations comprising:
obtaining cell information;
when the cell information meets a preset low-load condition, dividing, based on the cell information, to-be-processed broadcast messages into a plurality of broadcast message groups, wherein the to-be-processed broadcast messages are all broadcast messages to be sent in a time window, each broadcast message group corresponds to one time window, and a length of each time window is equal to a synchronization signal sending periodicity;
wherein the cell information is downlink resource utilization; and the operations further comprise:
based on the downlink resource utilization being less than a first preset threshold, determining that the cell information meets the preset low-load condition and
when the downlink resource utilization is less than the first preset threshold and the downlink resource utilization is greater than or equal to a second preset threshold, dividing the to-be-processed broadcast messages into a first quantity of broadcast message groups; and
when the downlink resource utilization is less than the second preset threshold, dividing the to-be-processed broadcast messages into a second quantity of broadcast message groups, wherein both the first quantity and the second quantity are positive integers greater than 1, the first quantity is less than the second quantity, and the second quantity is less than or equal to a total quantity of broadcast beams configured for a cell;
determining, based on a preset correspondence between a broadcast message and a broadcast beam, a broadcast beam group corresponding to each broadcast message group and a broadcast beam for sending no broadcast message in each time window;
sending the broadcast message group in each time window by using the broadcast beam group; and
shutting down, in each time window, the broadcast beam for sending no broadcast message.
