Spectrum channel sharing system
View Patent ↗A spectrum channel sharing system may coordinate a shared usage of one or more spectrum channels between a first communication system and a second communication system. The first communication system may transmit a request to the second communication system to clear communication traffic associated with the second communication system from a spectrum channel. The first communication system may then initiate a communication session on the spectrum channel after the communication traffic associated with the second communication system has been at least partially cleared from the spectrum channel.
