Patent ID: 11637729

Abstract:
This application provides a reference signal generation method in which a terminal device or a network device generates a reference signal by using a pseudo-random sequence initial factor cinit provided in the embodiments of this application. Compared with a solution in the current technology, the reference signal generation method can support a relatively large quantity of reference signal sequences, to better meet the requirements of different 5G scenarios. The reference signal generation method may include obtaining a reference signal sequence based on a pseudo-random sequence initial factor cinit, and mapping the sequence to one or more OFDM symbols. The pseudo-random sequence initial factor cinit is related to a parameter d, d=max(log2(nID,max+1)−10,0) or d=max(log2)(nID,max+1)−12,0), max represents that a larger value is selected from two values, and nID,max represents a maximum value of a reference signal sequence ID.
