Abstract: In a transmission parameter configuration method, a first node receives a transmission configuration message, where the transmission configuration message includes transmission configuration index information and a transmission parameter corresponding to the transmission configuration index information, and the transmission configuration index information is used to identify different transmission modes. The first node obtains a transmission indication message, where the transmission indication message includes the transmission configuration index information, and the transmission indication message is used to indicate to the first node to apply the transmission parameter corresponding to the transmission configuration index information. The first node performs, based on the transmission configuration index information, data transmission by using the transmission parameter corresponding to the transmission configuration index information. The method can meet requirements of more application scenarios, support more transmission modes, and reduce overheads caused by transmission parameters.

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: Various embodiments provide a relay transmission method, where a first node is a parent node of a second node. In those embodiments, a request message from the first node can be received by the second node, where the request message is configured to request the second node to become a parent node of the first node. Still in those embodiments, indication information can be sent, by the second node, to the first node, where the indication information is used to indicate that a downlink beam sent from the second node to the first node after the second node becomes the parent node is the same as or similar to an uplink beam sent from the second node to the first node when the first node is the parent node. The indication information may be carried in a response message for the request message.
