SIGNAL PROCESSING METHOD AND DEVICE, AND BASE STATION AND USER EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2018/192213
Kind Code:
A1
Abstract:
Disclosed is a signal processing method, comprising: a base station receiving phase tracking reference signals (PTRS) of n user equipments scheduled thereby at a pre-set time-frequency resource, wherein n is a positive integer greater than 1; and the base station decoding the PTRSs of the n user equipments according to codewords corresponding to the PTRSs of the n user equipments and orthogonal cover codes (OCC), wherein the PTRSs of the n user equipments and the OCCs are mutually orthogonal based on the codewords. The embodiments of the present invention can solve the problem of resource multiplexing between phase tracking reference signals (PTRS) of a plurality of users, and can better ensure the estimation performance of a frequency offset and phase noise of each user equipment.
