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.

This application is a continuation of U.S. application Ser. No. 16/957,735, filed on Jun. 25, 2020, which is a national phase application of PCT Application No. PCT/US2019/015372 filed on Jan. 28, 2019, which claims priority to European Application No. 18 156 300.8 filed on Feb. 12, 2018, each of which are herein incorporated by reference in their entirety.
The disclosure relates to an access point (AP) device and techniques 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. The disclosure further relates to integration of a decentralized network such as WiFi into a centralized network such as Spectrum Access System (SAS) or Licensed Shared Access (LSA) system through application layer communication using standardized Application Programming Interfaces (APIs).
權(quán)利要求
The invention claimed is:1. 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 free of a transmission reservation by the Incumbent, the AP device comprising 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; wherein generating the group comprises assigning a group ID to a plurality of users affected by the message from the incumbent requesting vacating of the spectrum. 2. The AP of claim 1 , wherein performing the spectrum management operation comprises sending an instruction for the group of users to vacate the spectrum. 3. The AP of claim 2 , wherein the instruction for the group of users to vacate the spectrum comprises an instruction for the group of users to enter a sleep mode. 4. The AP of claim 1 , wherein performing the spectrum management operation comprises blocking Media Access Control addresses of each user of the group of users. 5. The AP of claim 1 , wherein sending the instruction comprises sending the instruction to each user corresponding to the group ID. 6. The AP of claim 1 , wherein generating the group of users affected by the message from the incumbent requesting vacating of the spectrum comprises generating a group of users utilizing the spectrum in the message from the incumbent. 7. The AP of claim 1 , wherein the AP is further configured to receive a spectrum availability indication from the Incumbent for use of the spectrum; wherein the spectrum management operation is a first spectrum management operation; and wherein the AP is configured to perform a second spectrum management operation in response to the spectrum availability indication from the Incumbent. 8. The AP of claim 7 , wherein the first spectrum management operation comprises the AP sending an instruction to the group of users to vacate the spectrum; and wherein the second spectrum operation comprises the AP sending an instruction to the group of users that they may resume using the spectrum. 9. The AP of claim 7 , wherein the first spectrum management operation comprises the AP sending an instruction to the group of users enter a sleep mode; and wherein the second spectrum operation comprises the AP sending an instruction to the group of users to exit the sleep mode. 10. The AP of claim 7 , wherein the first spectrum management operation comprises the AP blocking Media Access Control addresses of each user of the group of users; and wherein the second spectrum operation comprises the AP stopping blocking Media Access Control addresses of each user of the group of users. 11. The AP device of claim 10 ,wherein the first application programming circuitry is coupled to the at least one UE via a decentralized wireless communication network. 12. The AP device of claim 10 ,wherein the second application programming circuitry is configured to interact with the first application programming circuitry via a first external application programming interface (API). 13. The AP device of claim 10 ,wherein the second application programming circuitry is configured to interact with the central controller via a second external application programming interface (API). 14. The AP device of claim 10 ,wherein the second application programming circuitry comprises a data stack configured to interact with a corresponding data stack of the central controller via the second external API. 15. The AP of claim 1 , further comprising a network interface with a controller of the hierarchical communication system, wherein the controller comprises a Spectrum Access System (SAS) controller or a Licensed Shared Access (LSA) controller, wherein the processor is configured to receive the message from the incumbent requesting vacating of the spectrum via the network interface. 16. The AP device of claim 1 , comprising:a user interface with the at least one UE, wherein the spectrum management operation comprises sending a message to the group of users to force the group of users into a mode protecting use of the spectrum by the Incumbent via the user interface; and wherein the processor is configured to send a message enabling transmission of the group of users using spectrum via the user interface to the at least one UE. 17. The AP device of claim 1 , wherein the processor is configured to transmit a message to the group of users indicating availability of reserved spectrum to UEs belonging to the affected groups of users. 18. The AP device of claim 1 , comprising:a first application programming circuitry configured to control a UE corresponding to a user the in group of users; and a second application programming circuitry comprising an interface with the first application programming circuitry, wherein the second application programming circuitry is configured to interact with a central controller of the hierarchical communication system in order to allow the central controller to take over control of the at least one UE via the interface with the first application programming circuitry.
