Abstract
In a method for wireless communication, a receiver receives a first signal at a first radio frequency and determines the reception level of the first signal. The receiver receives data during a reception level of the first signal at the first radio frequency. The receiver decides, based on the determined reception level, whether at least one measurement is to be taken on a second signal transmitted at a second radio frequency. A radio station carries out the method.
Claims12
A method for operating a mobile station in a wireless communication network with a base station, the method comprising:
- receiving a first signal radiated inside a first radio coverage area at a first radio frequency;
- receiving threshold information at the first radio frequency, the threshold information relating to a reception level of the first signal;
- determining a received level of the first signal;
- determining a received level of a second signal radiated inside a second radio coverage area at a second radio frequency based on a comparison of the received level of the first signal and the threshold information, the second radio frequency being from a same radio technology as the first radio frequency, and the second radio coverage area overlapping the first radio coverage area,
- wherein the threshold information relates to a measure of the received level of the first signal at the edge of the second radio coverage area, and
- wherein the first frequency and the second frequency comprise non-overlapping frequency bands.
A radio station for a radio communication system, comprising;
- a receiver operable to receive a first signal radiated inside a first radio coverage area at a first radio frequency and receive threshold information at the first radio frequency, the threshold information relating to a reception level of the first signal;
- a detector operable to determine a received level of the first signal;
- and
- a decider operable to decide by comparing the received level of the first signal and the threshold information, whether to perform a measurement of a received level of a second signal radiated inside a second radio coverage area at a second radio frequency, the second radio frequency being from the same radio technology as the first radio frequency, and the second radio coverage area overlapping the first radio coverage area,
- wherein the threshold information relates to a measure of the received level of the first signal at the edge of the second radio coverage area, and
- wherein the first frequency and the second frequency comprise non-overlapping frequency bands.
