    摘要: This application discloses a random access method and apparatus. The 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, and the first transmit power is a power used when the first node sends downlink information to the second node over a first link; and the first link is a link between the first node and the second node, and the first node is an upper-level device of the second node; and determining, by the first node, the first transmit power based on the first information. Therefore, the first node determines the first transmit power based on the first information, and uses the first transmit power when sending the downlink information to the second node over the first link, so that interference between signals received by the second node can be reduced.

    摘要: Embodiments of this application provide a signal transmission method and a communications apparatus. When finding that a success rate of an uplink signal is low, a network device determines a target transmission mode, includes the target transmission mode in first indication information, and sends the first indication information to a terminal device, so that the terminal device sends a signal to the network device in the target transmission mode. In this process, the network device controls a transmission mode of the terminal device, to be specific, the network device determines the target transmission mode based on network load, so that a probability that a large quantity of terminal devices use an EDT mode or a first random access mode can be effectively reduced, that is, a collision probability in the EDT mode and a collision probability in the first random access mode are reduced, and a success rate of sending an uplink signal by the terminal device in an idle state in a grant-free mode is improved.
