Title:
CHANNEL RECONSTRUCTION
Document Type and Number:
WIPO Patent Application WO/2024/103248
Kind Code:
A1
Abstract:
Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of channel reconstruction. In a method, a first device receives a signal from a second device via a set of receiving antenna elements over a channel, the signal is associated with a plurality of pilots transmitted by the second device. The first device determines an estimate of a plurality of pairs of and receiving angles associated with the channel, based on the received signal, the plurality of pilots and a plurality of orthogonal spatial directions. A spatial direction of the plurality of orthogonal spatial directions is indicated by a pair of transmitting and receiving spatial frequencies. Then, the first device reconstructs the channel based on the received signal, the plurality of pilots, and the estimate of the plurality of pairs of and receiving angles.
