    Abstract: Disclosed are a beam scanning method and a related device, used for solving the problem that, during the existing process of determining the optimal transceiving beam by performing traversal search on a combination of potential transceiving beams, a large amount of system overhead needs to be occupied, thus reducing the system efficiency and the adaptability to a time-varying channel. The method comprises: a first communication node determines at least one transmitted beam according to the optimal receiving beam group between a receiver of the first communication node and a transmitter of a second communication node; the first communication node sequentially sends a signal to the second communication node by means of the transmitter according to the determined at least one transmitted beam until the optimal transmitted beam is determined.

    Abstract: Embodiments of the present application relate to the field of communications, and in particular, to a control information sending method and receiving method, a sender and a receiver, which are used for sending DCIs corresponding to DCI types to the receiver, thereby improving simplicity of interference suppression performed by the receiver. In the embodiments of the present application, a sender flexibly and optionally sends a first class of DCIs and/or a second class of DCIs. On one hand, when a receiver performs interference suppression on received interference signals, parameters of interference signals comprised in DCIs corresponding to a type of a received second class of DCIs can be used for interference suppression, thereby improving simplicity of interference suppression performed by the receiver; and on the other hand, when the receiver does not perform interference suppression on the received interference signals, a sender can send DCIs corresponding to a type of a first class of DCIs, and the first class of DCIs does not comprise the parameters of an interference signals, thereby reducing load capacity of data transmission and further reducing data processing complexity of the receiver.
