摘要： Embodiments of the present disclosure disclose example network device, terminal device, and method for notifying information about a power difference. One example network device includes one or more processors performing operations that include determining first information and sending, by a transceiver of the network device, the first information to a terminal device. The first information indicates a first power difference that is associated with a first waveform. The first power difference is an offset between a power of a reference signal and a power of a first physical downlink shared channel (PDSCH) on which the first waveform is used.

摘要： 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.

摘要： A method for wireless communications includes receiving signaling for indicating a time division duplexing (TDD) frame structure configuration from a base station. The TDD frame structure configuration corresponds to a time duration of 0.1 ms, 0.125 ms, 0.2 ms, 0.25 ms, 0.5 ms, or 1.0 ms, the TDD frame structure configuration including two switching points between downlink transmissions and uplink transmissions. The method further includes communicating downlink and uplink transmissions according to the TDD frame structure configuration. The TDD frame structure configuration may further include a guard period for separating the first downlink transmission and the first uplink transmission in the time domain.

摘要： 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.
