我们考虑在有限的一组运营商之间共享频谱，这些运营商具有相似的频谱访问权限。设计了一种作用于RAN级的协调协议。该协议是非合作的，但假设一组协商规则的协议。信令开销低，并且不假设竞争者的信道状态信息的知识。不涉及货币交易;相反，频谱共享基于RAN内部虚拟货币。该协议既适用于互租场景，也适用于运营商组成频谱池的场景。该协议对运营商的干扰和负载变化做出反应，并在模拟的小小区场景中显示出收益。
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.
