Title:
METHOD FOR PROCESSING REFERENCE SIGNALS, APPARATUS AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/056189
Kind Code:
A1
Abstract:
Disclosed in the present application are a method for processing reference signals, an apparatus and a system. The method comprises: generating a sequence of reference signals, wherein the phase αi, l of a cyclic shift of the sequence of reference signals is related to a random phase factor, i indicates that the reference signals are sent by using an i-th port, and l represents the number of symbols, symbol index or symbol number of the mapping of the sequence; and mapping the sequence onto one or more symbols, and sending same. In the technical solutions provided in the embodiments of the present invention, symbol-level phase rotation is added when generating the sequence of reference signals such that the cyclic shifts of reference signals having different symbols on the same port are different, which may reduce the interference between terminals and improve the accuracy of delay estimation.
