Title:
METHOD AND APPARATUS FOR PROCESSING REFERENCE SIGNAL
Document Type and Number:
WIPO Patent Application WO/2021/018279
Kind Code:
A1
Abstract:
Provided in embodiments of the present application are a method and apparatus for processing a reference signal. The method comprises: determining a base sequence on the basis of a first Zadoff-Chu sequence that has a length of Nzc; according to the base sequence, generating a reference signal sequence that has a length of M; and then generating a reference signal according to the reference signal sequence and sending same to a receiving end. The base sequence is one of L candidate base sequences, wherein L≥31 and L is an integer; and the value of Nzc is a prime number in the set [97,431]. In the embodiments of the present application, since the Zadoff-Chu sequence used for generating the candidate base sequence is longer, the number of candidate base sequences increases, so that the number of base sequences available in one cell may be increased, thus satisfying the demand for a large number of terminals in the one cell to require more base sequences in a scenario in which the number of terminals in the cell has greatly increased, and the terminals in the cell do not need to make different terminals take turns sending uplink reference signals by means of a time division manner, which ensures the performance of a system.
