L1 and L3 only communications
When S-CPE is located inside of MR-BS area
Centralized scheduling or distributed scheduling mode is available depending on network conditions
Centralized scheduling mode (CC2)
Distributed scheduling (CC3)
When S-CPE is located outside of MR-BS area (CC4)
Distributed scheduling mode is only available since S-CPE can not synchronize to MR-BS
R-CPE shall perform as a local BS
Example of CC2 or CC3
Example of CC4

CPE Network Operations
Initialization
CPE performs self test.
CPE acquires the antenna gain information.
CPE acquires the device capabilities (e.g, network mgmt, relay, MIMO, geolocation capability, etc.) to confirm the desired operations of CPE

Synchronization
CPE senses for and synchronizes to WRAN services. The sensing thread also begins during this step to detect broadcasting incumbents.
Synchronizing to MR-BS (CC1, CC2, CC3, CC5, CC6)
Local synchronizing to R-CPE (CC3, CC4, CC6)
CPE presents sensing results to the higher layers.
CPE chooses a WRAN service.
Choosing MR-BS
CC1 (Shall), CC2 (Shall), CC5 (Shall)
CC3 (May)
Choosing R-CPE
CC4 (Shall), CC6 (Shall)
