Abstract: Embodiments of the present invention provide a communication method. A first network device configures power configuration information for each of at least two precoding matrix groups, and sends the power configuration information to a second network device. The power configuration information is used to indicate a power configuration of a corresponding precoding matrix group of the at least two precoding matrix groups, and the at least two precoding matrix groups belong to a same resource used to measure channel state information CSI. When the second network device performs CSI measurement, different power values of different precoding matrix groups can be considered, thereby increasing accuracy of the CSI measurement.

Abstract: A signal scrambling method and apparatus, and a signal descrambling method and apparatus are disclosed. In the signal scrambling method, a communications apparatus scrambles a signal by using a scrambling sequence, and sends the scrambled signal. In the signal descrambling method, a communications apparatus receives a signal, and descrambles the signal by using a scrambling sequence. An initial value of the scrambling sequence is determined based on a time unit number corresponding to a frame structure parameter used for transmitting the signal, so that different scrambling sequences can be used to scramble signals that are transmitted by using different frame structure parameters. Therefore, interference randomization can be implemented for signal scrambling, and this can be applicable to various application scenarios in 5G NR to improve performance.
