  Abstract: In this paper, we exploit the correlation between nearby user equipment (UE) and develop a deep learning-based channel state information (CSI) feedback and cooperative recovery framework, CoCsiNet, to reduce the feedback overhead. The CSI can be divided into two parts: shared by nearby UE and owned by individual UE. The key idea of exploiting the correlation is to reduce the overhead used to repeatedly feedback shared information. Unlike in the general autoencoder framework, an extra decoder is added at the base station to recover shared information from the feedback CSI of two nearby UE, but no modification is performed at the UE. For a UE with multiple antennas, we also introduce a baseline neural network architecture with long short-term memory modules to extract the correlation of nearby antennas. We propose two representative methods for converting CSI into bitstreams at the UE through quantization and binarization. Given that the CSI phase is not sparse, we propose a magnitude-dependent phase feedback strategy that introduces CSI magnitude information to the loss function of the phase feedback. Simulation results show the effectiveness of the proposed CoCsiNet and explain the mechanism of the CoCsiNet via parameter visualization.
