This paper exploits device-to-device (D2D) communications for exchanging the downlink channel state information (CSI) among users, so that the users can design better feedback strategies. Using a team decision approach for the feedback and precoding design, the users and the base station (BS) minimize a common mean squared error (MSE) metric based on their individual observations on the imperfect global CSI. The solutions are found to take similar forms as the regularized zero-forcing (RZF) precoder, with additional regularizations to capture the uncertainty of the exchanged CSI. Numerical results demonstrate superior performance of the proposed scheme over all D2D qualities.
