Abstract: The present disclosure discloses a method for transmitting an uplink measurement reference signal. The method is applied to a network-side device and includes the following operations: first, receiving, by the network-side device, an uplink measurement reference signal sent by user equipment, where the uplink measurement reference signal carries downlink interference information of a downlink channel of the network-side device; and then, performing downlink interference estimation on the uplink measurement reference signal, to obtain the downlink interference information. Compared with the prior art in which a base station cannot obtain downlink interference information of a downlink channel used by user equipment, in the present disclosure, the network-side device can effectively schedule the user equipment based on the downlink interference information, thereby improving scheduling efficiency, and improving data transmission efficiency of the downlink channel.

Abstract: This application discloses a precoding information sending solution and a precoding information feedback solution. A base station generates a signaling indicator and sends the signaling indicator to user equipment. The signaling indicator indicates related information about a precoding matrix set determined by the base station from a stored codebook, where the precoding matrix set belongs to a subset of the stored codebook. The user equipment selects a precoding matrix according to the signaling indicator sent by the base station, and sends a precoding matrix indicator PMI to the base station. The precoding matrix is selected according to a precoding matrix set and a feedback is performed. Therefore, complexity of searching for the precoding matrix and precoding feedback bits may be reduced.
