Abstract: This application provides a resource measurement method and an apparatus. A terminal receives measurement configuration information including N resource sets, and determines, based on a value of N, to send a first measurement result or a second measurement result to a network device. Specifically, the terminal sends the first measurement result to the network device when N>1, where the first measurement result is used to indicate m resources, downlink signals corresponding to the m resources can be simultaneously received by the terminal, and the m resources are in a one-to-one correspondence with m resource sets in the N resource sets. The terminal sends the second measurement result to the network device when N=1.

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.

Abstract: This application provides a resource processing method and apparatus. The method includes: determining, by a network device, at least two beams that need to be transmitted; determining, by the network device, a time-frequency resource corresponding to each of the at least two beams; and determining, by the network device, a part of the time-frequency resource corresponding to each beam to serve as a common search space, where the part that corresponds to the common search space and that is of the time-frequency resource is used to carry control information transmitted to a terminal device. The resource processing method and apparatus provided in the embodiments of this application can ensure that all terminal devices detect a complete common search space when the terminal devices are distributed in different directions.
