Abstract: A communication method and a device are provided. The method includes: Two thresholds are set on a terminal device side: a first threshold and a second threshold. A terminal device may determine a cause for a radio link failure RLF based on a value relationship between a measurement result of a radio signal and the two thresholds, and further may use different handling manners depending on different RLF causes. According to the foregoing method, the terminal device can more accurately locate the cause for the RLF, and perform corresponding handling, to quickly resume communication, meet a service requirement of an industrial scenario, and the like.

Abstract: A beam adjustment assembly is provided. The assembly includes a phase shifter and a connecting plate. The phase shifter includes a circuit board and main dielectric slabs configured to shift a phase. The circuit board is provided with a first strip and a second strip that are spaced. The first strip and the second strip are configured to respectively connect to radiating elements of an antenna. The connecting plate is slidably assembled on the circuit board and is configured to control an electrical connection between the first strip and the second strip. When sliding, the main dielectric slab can push the connecting plate to slide, to control a quantity of radiating elements in the antenna system. It can be learned from the foregoing description that, in this application, the sliding of the main dielectric slab in the phase shifter is used as a driving mechanism of the connecting plate.

Abstract: This application relates to the field of communications technologies, and discloses a resource configuration method and a node. The method includes: sending, by an parent node of a first node, first configuration information to the first node; and then determining, by the first node based on the first configuration information, a second resource for communication between the first node and a child node served by the first node. In this way, the determined second resource can implement orthogonalization between DMRS ports of an access link of the first node and a backhaul link of the first node, and therefore, link performance is improved.

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.
