摘要

An access point (AP) device for controlling spectrum usage of a hierarchical communication system, in which a spectrum reserved for an Incumbent is usable by at least one user equipment (UE) for transmission when the spectrum is not required by the Incumbent, is disclosed. The AP device includes a processor configured to receive a message from the Incumbent requesting vacating of a spectrum; generate a group of users affected by the message from the Incumbent requesting vacating of the spectrum; and perform a spectrum management operation on the group of users.

The second application programming circuitry 803 may comprise a data stack 422 configured to interact with a corresponding data stack 442 of the central controller 440 via the second external API. The first application programming circuitry 802 may comprise a WiFi stack. The second application programming circuitry 803 may be coupled via an Internet Protocol (IP) interface 424 with the central controller 440 of the hierarchical communication system as shown in FIG. 4.

FIG. 9 is a block diagram illustrating an exemplary central controller 900, e.g. an SAS controller according to the disclosure.

The central controller 900 is a controller of a hierarchical communication system, in which a spectrum reserved for an Incumbent is usable by at least one user equipment (UE) for transmission when the spectrum is not required by the Incumbent, e.g. as described above with respect to FIGS. 4 to 9. The central controller 900 comprises a processor 901.

The processor 901 is configured to indicate an access point (AP) device (connected at the left side of FIG. 9 with the AP device 900) to enforce the at least one UE into a mode protecting use of the spectrum by the Incumbent (e.g. via message “request vacating of spectrum” 811 depicted in FIG. 9) based on a spectrum request indication 911 from the Incumbent (arriving from an Incumbent at the right side of FIG. 9).
