Claim 14:
15. A method for managing a shared spectrum among a plurality of BSs, the method comprising:
obtaining coexistence measurement reports (CMRs) from the plurality of BSs, each CMR including a plurality of information elements that indicate interference relationships between BSs;
identifying interference relationships among the plurality of BSs based on the CMRs;
assigning 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
transmitting a spectrum access grant (SAG) to the set of BSs, wherein the SAG includes BAU assignments for the set of BSs.
