Unified spatial operations for dynamic medium sharing is disclosed in which a non-priority transmitter detects a priority reservation reference signal (RRS) over a shared spectrum from a high-priority transmitter The shared spectrum is shared by the non-priority transmitter with at least one high-priority communication pair. The high-priority communication pair includes a high-priority transmitter and the high-priority receiver. After detecting the RRS, the non-priority transmitter generates a non-priority channel estimate for a first channel between the non-priority transmitter and a non-priority receiver and a priority channel estimate for a second channel between the non-priority transmitter and the priority receiver. The non-priority transmitter transmits data on the shared spectrum using a transmission precoder determined using the non-priority channel estimate and the priority channel estimate, wherein the transmission precoder aligns transmission of the data to minimize interference with the high-priority receiver.
