Abstract

The described techniques provide for partitioning resources to coordinate wireless communications between one or more network operating entities within a shared spectrum. Partitioning resources may include assigning certain types of communication for each network operating entity to certain time intervals within a larger time frame. For example, a network operating entity may be assigned time intervals for exclusive communication, time intervals for prioritized communication with respect to other network operating entities, and time intervals for opportunistic communication.
