Abstract: Embodiments of this application provide a precoding matrix indication method, a communications apparatus, and a storage medium. A precoding matrix of each of K frequency-domain units satisfies W=W1×W2, and elements in W2 in the K frequency-domain units are represented by P elements that are relatively few. A terminal device reports third indication information, where the third indication information includes first indication information and the second indication information, and the first indication information and the second indication information are independently encoded. The first indication information is used to indicate the P elements, and the second indication information is used to indicate P. Therefore, the terminal device can adjust a quantity of information bits of the second indication information based on a channel condition change, thereby improving precoding matrix reporting efficiency.

Abstract: A downlink control channel transmission method, a receiving network element, and a sending network element are provided, to improve accuracy of beam measurement. A receiving network element obtains target downlink control information (DCI) on a first target control channel candidate in a target control channel candidate set, where the target DCI is DCI of the receiving network element, and the first target control channel candidate includes one or more control channel element groups (CCEGs); the receiving network element determines, based on the target DCI, a quantity of measurement reference signals and a time-frequency resource corresponding to each measurement reference signal; the receiving network element measures each measurement reference signal, to obtain channel quality information corresponding to each measurement reference signal; and the receiving network element reports the channel quality information corresponding to each measurement reference signal to a sending network element.

Abstract: This application provides a method for determining a precoding matrix set, so as to avoid a case in which a relatively large quantity of precoding matrices in a precoding matrix set cannot be used, thereby improving system performance. A terminal device receives indication information from a network device, and determines a second precoding matrix set front a first precoding matrix set whose rank is R based on the indication information. Each precoding matrix W in the first precoding matrix set satisfies W=W1×W2, the second precoding matrix set is a proper subset of the first precoding matrix set, and the second precoding matrix set does not include W=W1×W2 that satisfies the specific condition in the first precoding matrix set.

Abstract: A positioning signal sending method and apparatus are provided. A first signal is generated, where duration of a first rising edge of the first signal is less than duration of a first falling edge, the duration of the first rising edge is duration of a rising edge of a main lobe waveform of the first signal, and the duration of the first falling edge is duration of a falling edge of the main lobe waveform of the first signal; and the first signal is sent. In embodiments of this application, rising time of a main lobe waveform of a signal generated is short, and shorter rising time of the main lobe waveform is more conducive to distinguishing two adjacent paths or identifying a first arrival path of a received signal.
