This paper considers a decode-and-forward (DF) multi-way massivemultiple-input multiple-output (MIMO) relay system where many users exchangetheir data with the aid of a relay station equipped with a massive antennaarray. We propose a new transmission protocol which leverages successivecancelation decoding and zero-forcing (ZF) at the users. By using properties ofmassive MIMO, a tight analytical approximation of the spectral efficiency isderived. We show that our proposed scheme uses only half of the time-slotsrequired in the conventional scheme (in which the number of time-slots is equalto the number of users [1]), to exchange data across different users. As aresult, the sum spectral efficiency of our proposed scheme is nearly double theone of the conventional scheme, thereby boosting the performance of multi-waymassive MIMO to unprecedented levels.
