摘要： The present invention discloses an information transmission method. The method includes: A network device configures first beam sequence information, where the first beam sequence information is used to indicate a plurality of pieces of first identification information, and each of the plurality of pieces of first identification information is used to indicate one beam that carries a transmission signal; the network device sends the first beam sequence information to a terminal device; and the network device performs signal transmission with the terminal device, where the beams indicated by using the plurality of pieces of first identification information are used for the signal transmission. Embodiments of this application further provide a network device, a terminal device, and a storage medium. The embodiments of the present invention are applied to a scenario in which the terminal device moves regularly. The network device configures the first beam sequence information and sends the first beam sequence information to the terminal device, so that both the network device and the terminal device can learn of a time and a beam for communication. Therefore, beam indication does not need to be performed once for each time of communication, thereby saving signaling resources.

摘要： Embodiments of this application provide a relay transmission method, where a first node is a parent node of the second node. The method includes: receiving, by the second node, a request message from the first node, where the request message is used to request the second node to become a parent node of the first node; and sending, by the second node, indication information 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. The first node may learn of, through the indication information, information about a transmit beam used by the second node after switching. Therefore, an additional beam search or beam training is not required in a switching process.

摘要： Embodiments of this application disclose a beam training method, apparatus, and system. In a downlink beam training process, a terminal device performs beam training by determining interference-related indication information, a selection criterion for a beam to be reported in a group-based reporting manner, and a rank Rank condition, and selects and reports a beam satisfying a related factor condition, to implement on-demand downlink beam training. In an uplink beam training process, based on a gain adjustment indication of a network side, uplink beam training is performed in consideration of a gain factor, so that on-demand uplink beam training is implemented. In this technical solution, different factors such as interference and a channel condition are considered in a beam training process, so that effective on-demand beam training can be implemented.
