Abstract: A reference signal sending method and a communications device are provided. The reference signal sending method includes: generating, by a first device, a tracking reference signal, where the tracking reference signal corresponds to a DMRS port that is used by the first device when the first device sends data to a second device; mapping, by the first device, the tracking reference signal to a time-frequency resource that is used by the first device when the first device sends the data to the second device through the DMRS port, where the tracking reference signal is mapped to at least two modulation symbols on a same frequency resource in one transmission slot; and sending, by the first device, the tracking reference signal mapped to the time-frequency resource to the second device.

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.
