To enable coexistence in unlicensed bands or other shared spectrum, operators that deploy cellular coverage in unlicensed bands can broadcast and receive over-the-air (OTA) signaling messages that carry coexistence information such that the operators can adjust one or more parameters used to provide the cellular coverage in the unlicensed bands and thereby enable inter-operator coexistence. For example, the operators may coordinate the particular OTA signaling configuration used to carry the coexistence information and thereby enable each operator to learn information that the other operator (s) are using and thereby reduce interference on time, frequency, and/or spatial resources that may be shared among the operators providing the cellular coverage in the unlicensed bands. Furthermore, a user equipment (UE) that receives and decodes the OTA signaling messages exchanged among the operators …
