20090149208 | Method and apparatus to select collaborating users in spectrum sensing - In a first time interval TI a first frequency band FB is pseudorandomly selected from a designated spectrum, and a first analysis result is determined by sensing the first FB during the first TI and then transmitted. In a second TI a second FB is pseudorandomly selected from the designated spectrum, and a second analysis result is determined by sensing the second FB during the second TI and then transmitted. Where multiple devices do this the entire spectrum is sensed, each band by a subset of devices that changes at each TI, and so any unused or underutilized spectrum is searched by the collaborative spectrum sensing, which avoids propagation problems such as fading. Also, a central node can assure various collaborating users report different FBs in different TIs such that the subset of reporting users changes for at least one of the bands in each subsequent reporting TI. Sensing and communication can be performed in different portions of the same network defined transmission time interval. | 06-11-2009 |
20090232189 | Method, apparatus and computer program to efficiently acquire signals in a cognitive radio environment - Signal instances are detected from within a long period of a received radiofrequency RF signal envelope, grouped according to signal level, and periodicities are determined among the grouped signal instances. Periodicity of one of the groups is matched to a known periodicity, and a frequency domain is estimated at a time instance derived from the matched periodicity. If an expected frequency pattern is found that occupies the derived time instance in the estimated frequency domain, then a receiver is synchronized to a candidate signal that lies within the frequency pattern. Then content of the candidate signal is decoded and that content is used to access a cognitive radio system (e.g., register to the system, start the normal operation in the network such as spectrum detection and/or transmission in a traffic channel, etc.). | 09-17-2009 |

20120009874 | ALLOWED SPECTRUM INFORMATION DISTRIBUTION SYSTEM - A system for determining allowed channels for operating in unlicensed bandwidth. Initially, an apparatus may determine whether valid allowed channel information corresponding to the current position of the apparatus already exists in the apparatus. If the allowed channel information corresponding to the current position of the apparatus does not exist in the apparatus or is invalid, the apparatus may then determine if the allowed channel information can be provided by another apparatus. If the allowed channel information is available from another apparatus, this information may be requested from the other apparatus. Otherwise, the allowed channel information may be requested from a database. | 01-12-2012 |
