Systems and methods for dynamic allocation of spectrum among cross-interfering radio nodes of wireless communications systems are disclosed. Multiple radio nodes may be deployed within a geographical region, and each radio node may support wireless communication over spectrum in which access is arbitrated by an external service not under the control of the operator of the radio node. Each radio node is configured to detect radio conditions which may indicate coexistence between the radio node and a neighboring radio node. A network entity associated with the radio node obtains radio condition information and determines a coexistence status between the radio node and the neighboring radio node, such as whether coexistence with the neighboring radio node is tolerable or intolerable. The network entity reports an indication of the coexistence status to a spectrum server, and the spectrum server reallocates the spectrum among the radio nodes.
