Abstract: A signal sending method and a communication apparatus are disclosed. The signal sending method includes: A first communication apparatus determines N sequence sending modes, and sends a first signal based on a first sequence sending mode. The N sequence sending modes include the first sequence sending mode. The sequence sending modes indicate sending orders of N sequences, the N sequences are sent by the first communication apparatus in N periods, and N is a positive integer greater than 1. A cyclic shift value between sending orders indicated by any two adjacent sequence sending modes is 1. The first sequence sending mode is determined based on K second sequence sending modes and the N sequence sending modes, the K second sequence sending modes correspond to a second communication apparatus, and K is a positive integer.

Abstract: This application provides a device sensing method and an apparatus. The method includes: A sensing device sends a sensing signal, receives an echo signal of the sensing signal, and performs processing based on the echo signal. The sensing signal is generated based on a GCP with a length of N, where N is greater than or equal to 32. When N is equal to 32, 64, 128, 256, 512, or 1024, the GCP may be generated through generalized Boolean function mapping. When N is equal to 160, 320, 640, or 832, the GCP is a direct product of a first GCP and a second GCP, a length of the first GCP is N1, a length of the second GCP is N2, and N1×N2=N.
