Method and device for managing the operation of an apparatus, for example an mb-ofdm apparatus, in presence of an eventual interfering signal

A method of operating an apparatus in a wireless communication system, the method comprising:

• detecting at the apparatus an interfering signal emitted from a victim apparatus;
• estimating among different interference power regions respectively corresponding to different interference powers between a potential apparatus and a potential victim apparatus a region corresponding to an actual interference power between the apparatus and the victim apparatus;
• and
• adjusting at the apparatus transmission processing of a signal to be transmitted within the wireless communication system based upon the estimated interference power region for protecting the victim apparatus against interference.

A method of operating an apparatus in a wireless communication system and exchanging within the wireless communication system a multi-carrier modulated signal on a plurality of sub-carriers, the method comprising:

• detecting at the apparatus an interfering signal emitted from a victim apparatus on at least one sub-carrier from the plurality of sub-carriers;
• determining at the apparatus a path loss between the apparatus and the victim apparatus;
• determining from the path loss and an allowed interference level at the victim apparatus a threshold allowed transmit power on the at least one sub-carrier of a multi-carrier modulated signal to be transmitted from the apparatus;
• and
• adjusting at the apparatus processing of the multi-carrier modulated signal to be transmitted based upon the threshold allowed transmit power for protecting the victim apparatus against interference.

A method of operating a first wireless communications device in a wireless communication system, the method comprising:

• detecting a signal emitted from a second wireless communications device;
• estimating among different interference power regions respectively corresponding to different interference powers between a potential first wireless communications device and a potential second wireless communications device a region corresponding to an actual interference power with the second wireless communications device;
• and
• adjusting processing of a signal to be transmitted based upon the estimated interference power region.
