Radio spectrum is typically divided into radio frequency bands. Licenses for the usage of these frequency bands are provided to operators. Operators are often provided with the exclusive right to use the assigned radio resources. As a result, frequency bands may be used inefficiently. The alternative way of radio regulation is to coordinate the usage of the radio spectrum with unlicensed frequency bands. With unlicensed frequency bands, radio systems coordinate the usage of radio resources autonomously while operating. With this approach, resource sharing between radio systems is dif?cult to achieve. We refer to this sharing problem as coexistence problem, which is discussed with focus on the 5 GHz U-NII frequency band. A framework for de?ning coordination rules for the radio resource management, referred to as spectrum etiquette, is discussed. We de?ne spectrum etiquette rules for radio systems with different channel bandwidths. The rules are based on a set of actions like channel selection and listen-before-talk. By evaluating the rules with help of simulation, we provide an initial spectrum etiquette proposal.
