Rise in wireless data traffics requires innovative interference management techniques to meet the demand. Transmit cooperation among multiple base stations has been proposed as a solution to this challenge and improve throughput. For base stations equipped with massive MIMO arrays, a proposed subspace encoding technique can decouple the joint multicell resource allocation problems into independent problems for each cell. The subspace encoding in the multicell environment is analytically equivalent to a reduction of degrees of freedom in a single cell broadcast channel. Hence, the resulting computational and conceptual simplicity can be exploited to arrive at the optimal resource allocation for maximum throughput.
