Base station cooperation (BSC), also known as Cooperative Multi-Point (CoMP), has been identified as a key radio access technology for next-generation cellular networks. This work creates a foundational framework that extends BSC transmission to provide spatial spectrum sharing (SSS) through MIMO null beamforming while enjoying cooperative stream transmission. SSS is investigated by introducing the protected Gaussian MIMO broadcast channel (PGMBC), a GMBC with receive power constraints. Applications of the PGMBC are identified and its capacity region is derived. In addition, precoding schemes ...
