Resource reservation for shared spectrum systems

A network entity in a wireless communication system of shared spectrum resources, the network entity comprising:

• a processor configured to identify a coordination phase to identify at least one neighboring network entity using the shared spectrum resources and perform reservation of the shared spectrum resources;
• and
• a transceiver operably connected to the processor, the transceiver configured to:
• transmit, during the coordination phase, a coordination request message to the at least one neighboring network entity;
• and
• receive, during the coordination phase, a coordination response message from the at least one neighboring network entity,
• wherein the processor is configured to determine an amount of the shared spectrum resources to reserve based on the coordination response message, and
• wherein the transceiver is configured to transmit, to at least one terminal in a cell of the network entity, a data transmission using at least some of the determined amount of the reserved resources.
