METHODS FOR INTER-OPERATOR COEXISTENCE ON SHARED SPECTRUM OR UNLICENSED BANDS
First Claim
1. A method for inter-operator coexistence on unlicensed bands, comprising:
- exchanging one or more over-the-air (OTA) signaling messages between a first base station associated with a first operator and a second base station associated with a second operator, wherein the first operator and the second operator each provide cellular coverage in one or more unlicensed bands; and
adjusting one or more parameters that the first base station utilizes to provide the cellular coverage in the one or more unlicensed bands according to the one or more OTA signaling messages, wherein the one or more parameters are adjusted at the first base station to reduce interference on resources that the first operator and the second operator share to provide the cellular coverage in the unlicensed bands.

Abstract
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 may adjust one or more measurement parameters and/or operating parameters according to the coexistence information carried in the OTA signaling messages.
