Abstract: The present disclosure provides a downlink data transmission method, including: using a time-division multiplexing transmission mode in one transmission time interval; sending, by using a wide beam, a control signal to a user served in the current transmission time interval; and grouping users and sending data signals to different user groups by using different narrow beams. In one transmission time interval, time-division multiplexing is used, and a wide beam and a narrow beam are respectively used to transmit a control signal and a data signal. This can avoid a throughput bottleneck resulting from use of a transmission scheme that is based on frequency-division multiplexing only.

Abstract: This application discloses example power control methods and apparatuses. One example method includes receiving, by a first node, first information sent by a second node, where the first information is used to determine a first transmit power, where the first transmit power is a power used when the first node sends downlink information to the second node through a first link, where the first link is a link between the first node and the second node, and where the first node is an upper-level device of the second node. The first node can then determine the first transmit power based on the first information.
