Title:
DATA MAPPING METHOD, APPARATUS, AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/058550
Kind Code:
A1
Abstract:
Embodiments of the present invention disclose a data mapping method, apparatus, and device, for implementation of a data mapping method in which narrowband IQ data can be transmitted without changing a common public radio interface (CPRI). The method comprises: obtaining an IQ sampling rate fs' of a narrowband channel, a frequency fsf of a wideband channel, and a number N'A of antenna carriers of the narrowband channel, the frequency of the wideband channel being the inverse of a time slice, and the time slice being a time period specified in a wideband standard protocol; obtaining, by using the IQ sampling rate fs' of the narrowband channel and the frequency fsf of the wideband channel, the number S' of narrowband IQ sampling points corresponding to each narrowband antenna carrier, and the number K' of wideband time slices into which narrowband IQ sampling points of the N'A antenna carriers can be mapped; mapping the narrowband IQ sampling points of the N'A antenna carriers of the narrowband channel into the K' time slices of the wideband channel; and mapping the IQ sampling points of the narrowband channel into a basic frame of a common public radio interface in units of K' mapped time slices, to complete the mapping of the narrowband IQ sampling points in the common public radio interface.
