Abstract: A time division duplex (TDD) scheduling interval communicating transmissions in a first direction may include one or more regions for communicating in a second direction, where the first direction is a transmit direction and the second direction is a receive direction, or vice versa. A radio frame may include TDD scheduling intervals with such regions and/or TDD scheduling intervals without such regions for wireless communication, and these TDD scheduling intervals may further be configured in accordance with different frame structure configurations, such as different scheduling interval lengths, subcarrier spacings or symbol durations.

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.

Abstract: A scheduling method implements flexible scheduling in a relay network. A method includes: determining, by a first device, information about a transmission time difference, where the transmission time difference is a time difference between a control channel of a first link and a data channel that is of the first link and that is scheduled by the control channel of the first link; notifying a second device of the information about the transmission time difference; and performing, by the second device, scheduling based on the information about the transmission time difference. In this way, the second device determines whether a resource needs to be reserved for the data channel of the first link, and it is possible that a time division resource, a frequency division resource, or a space division resource is shared for data of the first link and data of a second link.
