Abstract
We consider spectrum sharing between a limited set of operators having similar rights for accessing spectrum. A coordination protocol acting on the level of the RAN is designed. The protocol is non-cooperative, but assumes an agreement to a set of negotiation rules. The signaling overhead is low, and knowledge of a competitor's channel state information is not assumed. No monetary transactions are involved; instead, spectrum sharing is based on a RAN-internal virtual currency. The protocol is applicable both in a scenario of mutual renting and when the operators form a spectrum pool. The protocol reacts to variations in interference and load of operators, and shows gains in a simulated small cell scenario.
