Abstract
Methods to protect incumbent communications in a shared band (e.g., shared by incumbents and shared band devices), are provided. In one example, a method includes receiving information, by a spectrum access controller (SAC) associated with a shared band, indicating usage of a sub-portion of a channel in the shared band. The method includes receiving, by the SAC, information associated with one or more shared band devices (SBDs) with spectrum notching capability (SNC) to reduce interference in the sub portion of the channel being used by the incumbent. The method includes determining, by the SAC, spectrum access information (SAI) for the one or more SBDs based at least in part on the SNC of the one or more SBDs. The method includes transmitting, from the SAC, SAI to the one or more SBDs, and SBDs accessing the channel according to the SAI.
