Title:
PHASE NOISE ESTIMATION METHOD AND APPARATUS, AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/143355
Kind Code:
A1
Abstract:
Embodiments of the present application relate to the technical field of communications and provide a phase noise estimation method and apparatus, and a system, which can improve the technical problem in the prior art that during precoding of PTRSs by transmitting ends, receiving ends cannot reasonably estimate phase noise corresponding to the PTRSs due to the introduction of a nonlinear modulo operation. The method comprises: a receiving end obtains first information and a first signal, and determines, according to the first information and first signal, an estimated value of the phase noise corresponding to a first PTRS, the first information being used for indicating a first parameter corresponding to the interference information of the first PTRS, the first parameter comprising one or more of a first phase set and a first amplitude set, the first signal being determined according to the first parameter and the interference information of the first PTRS, and the amplitude of the first signal satisfying a first threshold.
