    Abstract: Disclosed are a data transmission method and device. The method comprises: a sending end sending at least one synchronization signal (SI), with the SI carrying a first identifier; and at a time-frequency location of system information corresponding to the SI, sending the system information, the system information carrying information for indicating a second identifier, and identification information about the sending end comprising the first identifier and the second identifier. According to a mapping relationship between an SI and a first identifier, a receiving end can obtain the first identifier after detecting the SI; and by means of carrying information for indicating a second identifier in system information, the receiving end can obtain the second identifier after detecting the system information, so that the receiving end can obtain all the identification information about the sending end according to the first identifier and the second identifier.

    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.

    Abstract: The present invention relates to the technical field of wireless communications, and in particular, to a beam training method and device, for use in resolving the problems in the prior art of excessive time-consuming of a beam training process, large overhead of training signals, and relatively low efficiency. According to embodiments of the present invention, a transmit device sends beam training signals in two times. The first sending of a transmit beam training signal is for a receive device to select a transmit beam using a selected receive beam and report the transmit beam. The second sending is that the transmit device sends a receive beam training signal according to the transmit beam information report of the receive device, so as to train the received beam of the receive device. According to the embodiments of the present invention, an interactive beam training method is used to gradually search for the best transmit beam and receive beam, thereby avoiding completing beam training all at once, reducing beam training time and overhead, and improving efficiency.
