摘要

本文研究了存在小区间干扰(ICI)的多用户下行链路传输。在考虑的系统中，根据均方误差(MSE)准则，共同确定基站预编码和用户后编码，以管理用户间干扰(IUI)和用户间干扰(ICI)。与基于零强迫的预编码不同，本文提出的基于mse的预编码方案仍然有效，因为每个BS的发射天线数小于所有用户的接收天线总数。

Interference management over multicell broadcast channels

This paper is concerned with multiuser downlink transmissions in the presence of inter-cell interference (ICI). In the considered system, precoding at base stations (BS) and postcoding at users are jointly determined to manage both inter-user interference (IUI) and ICI under mean square error (MSE) criterion. Unlike zero-forcing based precoding, the proposed MSE-based precoding scheme still work as the number of transmit antennas at each BS is smaller than the total number of receive antennas at all users.
