Abstract: Modulated radio frequency (RF) packets are received from a wireless device, and converted to modulated baseband packets. Baseband parameters are derived from the modulated baseband packets. A baseband profile including the baseband parameters is created for the wireless device. A database including baseband profiles of wireless devices is accessed. The baseband profiles are classified under known device types based on baseband parameters included in the baseband profiles. The baseband parameters of the baseband profile are compared to corresponding baseband parameters of the baseband profiles in the database. If the comparing indicates a match between the baseband profile and one of the baseband profiles, the wireless device is classified under the known device type of the one of the baseband profiles, and the baseband profile is stored in the database under the known device type.

Abstract: A base station device of blanking a radio resource, includes: a base station selecting circuit to select a specific adjacent base station for coordinated multi-point (CoMP) transmission and reception; a CoMP transmission and reception control circuit to blank out the radio resource which is allocated equally as the radio resource, which is allocated by the specific adjacent base station for a terminal which receives the CoMP transmission and reception from the base station device and the specific adjacent base station; and a resource allocation information sharing circuit to share resource allocation information, which represents that the radio resource is blanked out, with other adjacent base stations except for the specific adjacent base station, such that the other adjacent base stations are capable of using the resource allocation information.
