Abstract: A communication method includes receiving first beam feedback information from a wide beam terminal, where the first beam feedback information includes information about a first wide beam and information about M wide beams whose signal quality meets a first condition, receiving second beam feedback information from a narrow beam terminal, where the second beam feedback information includes information about a second wide beam and information about N wide beams whose signal quality meets a second condition, receiving, from the narrow beam terminal, information about a first narrow beam, where the first narrow beam is a narrow beam covered by the second wide beam, and determining, based on the first beam feedback information, the second beam feedback information, and the information about the first narrow beam, whether to transmit downlink data to the wide beam terminal and the narrow beam terminal.
