Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: ,  propose a new retrospective interference alignment for two-cell multiple-input multiple-output (MIMO) interfering multiple access channels (IMAC) with    $M$   receive antennas per base station (BS) and    $K$   users per cell each with    $N$   transmit antennas. The key idea of the retrospective IA lies in   interference-purification   during phase 1 and 2, and   interference-repetition   during phase 3. On the basis of the proposed method,  show that the achievable sum degrees of freedom (sum-DoF) is equal to    $2M\left(\left\lceil\frac{2M}{N}\right\rceil+1\right)/\left(2\left\lceil\frac{2M}{N} \right\rceil+1\right)$   if    $K\le M   and    $\min\{2KN,M\}$   if    $NK \le M$   with completely delayed channel state information at the transmitters (CSIT) . It is shown that having delayed CSIT can strictly increase the sum-DoF compared to the case with no CSIT for cellular networks, especially for uplink scenarios.
