Methods for coexistence between operators over shared spectrum or unlicensed bands

摘要

To enable coexistence in the unlicensed band or other shared spectrum, operators deploying cellular coverage in the unlicensed band may use one or more parameters used by the operator to provide cellular coverage in the unlicensed band Can be broadcast and received over-the-air (OTA) signaling messages that carry coexistence information so that coexistence between operators can be enabled. For example, operators can coordinate specific OTA signaling configurations used to carry coexistence information so that each operator learns the information that other operators are using, thereby It may be possible to reduce interference on time, frequency, and / or spatial resources that may be shared among operators providing cellular coverage in an unlicensed band. Further, a user equipment (UE) that receives and decodes OTA signaling messages exchanged between operators adjusts one or more measurement parameters and / or operational parameters according to the coexistence information carried in the OTA signaling messages. be able to.
