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.

說明書

The SAS controller 504 transmits “make spectrum available to RLAN” message 612 to SAS SW stack 503 to indicate that spectrum shall be made available for RLAN 502. In the SAS SW stack 503 affected user groups are identified and users transmission is enabled 613. Then, SAS SW stack 503 transmits “indicate availability of spectrum to user groups” message 614 to RLAN 502 to indicate RLAN 502 of availability of spectrum to user groups. RLAN 502 transmits “indicate availability of spectrum to UE” message 615 to RLAN UE 501 to indicate the specific RLAN UE 501 about availability of spectrum. RLAN UE 501 answers with Acknowledgement 616. Then, RLAN 502 transmits Acknowledgement 617 to SAS SW stack 503 which transmits Acknowledgement 618 to SAS controller 504 which transmits Acknowledgement 619 to Incumbent 505.

The techniques disclosed above with respect to FIGS. 1 to 6, in particular the use of the above commands described with respect to FIGS. 5 and 6 can also be applied to provide specific guarantees in case that multiple secondary systems need to share access to the band (for example systems such as WiFi and MuLTEFire existing in the same band) so as to ensure their harmonious co-existence, e.g. as described in the following.
