Abstract
A method is provided for determining whether transmission signals are present in received signals, the method comprising: receiving a first signal via a first radio resource; receiving a second signal via a second radio resource; determining whether a first transmission signal is present in the received first signal based on the received second signal; and determining whether a second transmission signal is present in the received second signal based on the received first signal.
Claims18
A method for determining whether transmission signals are present in received signals, the method comprising:
- receiving a first signal via a first radio resource;
- receiving a second signal via a second radio resource;
- determining whether a first transmission signal is present in the received first signal based on the received second signal;
- and
- determining whether a second transmission signal is present in the received second signal based on the received first signal;
- wherein determining whether the first transmission signal is present in the received first signal comprises determining a measure of the average power of the received second signal and wherein it is determined whether the first transmission signal is present in the received first signal based on the determined measure of the average power of the received second signal;
- wherein the received second signal comprises a plurality of signal values and the measure of the average power of the received second signal is determined based on a combination of the signal values;
- and
- wherein for each signal value, a measure of the signal value based on the absolute value of the signal value is determined and the combination of the signal values is an average of the measures of the signal values.
