Efficient Enablement For Wireless Communication On License-Exempt Bands
First Claim
1. An apparatus, comprising:
- at least one processor; and
at least one memory storing a computer program;
in which the at least one memory with the computer program is configured with the at least one processor to cause the apparatus to at least;
enable a device for operation in a license exempt spectrum by providing to the device a list of available license exempt radio channels;
provide to the device a parameter indicating an interval at which contact verification signals are to be sent, in which the contact verification signals verify whether the list remains valid; and
repeatedly send the contact verification signals spaced in time from one another according to the interval.

Abstract
A fixed or Mode II device enables a Mode I device for license exempt operation by providing to it a list of available license exempt radio channels and a parameter indicating an interval at which contact verification signals CVSs are to be sent. The CVSs verify whether the list remains valid. The fixed/Mode II device then repeatedly sends contact verification signals spaced in time from one another according to the interval. In various embodiments the parameter may be an explicit indication (number of seconds or number of beacons between consecutive CVSs), or it may be implicit (derived from an ID of the fixed/Mode II or Mode I device or a frequency channel, in which the relevant ID is the parameter). A plurality of enabled Mode I devices each gets a device-specific list, and in one embodiment the interval is the same for each of them and the explicit indication is broadcast while in another the parameter is provided to each of them via unicast messages and the interval may differ.
