摘要： Embodiments of this application provide a data transmission method, a network device, and a terminal. When the method is performed by the terminal, the method includes: obtaining, a time-frequency resource used to transmit uplink data, where the time-frequency resource is at least one time-frequency resource block selected from a plurality of time-frequency resource blocks; each of the time-frequency resource blocks is corresponding to one piece of configuration information; and transmitting, the uplink data on the at least one selected time-frequency resource block based on configuration information of the at least one selected time-frequency resource block. The terminal may select a relatively narrow bandwidth to perform uplink transmission, to increase a transmit power of the terminal. In addition, the terminal performs the uplink transmission based on the corresponding configuration information, to further increase a transmit power. The network device perform demodulation, to improve demodulation efficiency and avoid generating a processing latency.

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.
