1. An electronic device for managing a shared spectrum among a plurality of base stations (BSs), the electronic device comprising:
memory comprising instructions for managing the shared spectrum; and
a processor operably connected to the memory, the processor configured to execute the instructions to cause the electronic device to:
obtain coexistence measurement reports (CMRs) from the plurality of BSs, each CMR including a plurality of information elements that indicate interference relationships between BSs;
identify interference relationships among the plurality of BSs based on the CMRs;
assign a set of BSs to one or more basic allocation units (BAUs) in a plurality of BAUs based on the interference relationships, wherein each BAU in the plurality of BAUs is a time/frequency unit, wherein the set of BSs includes a primary BS and a secondary BS, wherein the secondary BS can transmit in a period that is an offset from a start of the one or more BAUs after performing channel sensing for RF energy in a specified period in the one or more BAUs to determine that a transmission of the secondary BS in the one or more BAUs does not interfere with a transmission of the primary BS, and wherein the period is offset according to a predetermined offset; and
transmit a spectrum access grant (SAG) to the set of BSs, wherein the SAG includes BAU assignments for the set of BSs.
