Abstract: This application provides a PSCCH detection method and a communication apparatus. In the method, a first terminal device may detect a first PSCCH based on a resource included in a candidate resource set indicated by first indication information. This avoids overheads caused when the first terminal device needs to blindly detect the PSCCH, and helps reduce energy consumption. In particular, when a bandwidth is relatively large or there are a relatively large quantity of sub-channels, this can avoid overheads caused when the first terminal device needs to blindly detect the PSCCH.

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.
