This paper presents a high level description of an LTE system operating in license exempt bands. Since wireless networks potentially using different air interfaces may operate in these bands, coexistence is a challenge that needs to be addressed. This paper focuses on non-coordinated mechanisms for secondary users coexistence, and introduces a coexistence gap based method for LTE to dynamically share the spectrum with other secondary users. A simulation based analysis of the coexistence gap method is presented, and the results are compared with an energy based sensing channel access method.
