INTERFERENCE COORDINATION IN LICENSED SHARED RADIO FREQUENCY SPECTRUM

Abstract:

Methods, systems, and devices for wireless communications are described in which wireless nodes may use licensed shared radio frequency spectrum band for communications and one or more neighboring networks may use a same licensed shared radio frequency spectrum band. A second network of the one or more neighboring networks may have priority of use of the licensed shared radio frequency spectrum band within a particular geographic area. Disclosed techniques provide that nodes of each network may indicate an identification of the network, a network priority, or both, in over-the-air signaling. Wireless nodes may determine if another neighboring network is present based on the over-the-air signaling, may determine whether the other network has a higher priority, and may adjust one or more transmissions in the event that a higher priority network is identified, such as through reducing transmission power.
