Radio White Space Sensing
First Claim
1. A method of operating a user equipment comprising a receiver, the method comprising:
- obtaining information about a set of channels to be sensed in a sensing process, wherein each channel is associated with a respective one of a plurality of radio frequencies;
operating the receiver to obtain a radio frequency signal by simultaneously sensing two or more of the channels included in the set of channels;
measuring a total power level of the sensed two or more channels;
generating a comparison result by comparing the total power level of the sensed two or more channels with a predetermined power level; and
controlling the user equipment based on the comparison result.

Abstract
User equipment comprising a receiver obtains information about a set of channels to be sensed in a sensing process, wherein each channel is associated with a respective one of a number of radio frequencies. The receiver obtains a radio frequency signal by simultaneously sensing two or more of the channels included in the set of channels. A total power level of the sensed two or more channels is measured, and a comparison result is generated by comparing the total power level of the sensed two or more channels with a predetermined power level. The user equipment is controlled based on the comparison result. For example, if the total power level is below a threshold, then the sensed channels can be considered to not be in use by external transmission equipment.
