Patent ID: 8614969

Claim:
A method for broadcasting frequency policy information for cognitive radio communication by a policy broadcaster apparatus, the method comprising: generating a policy broadcasting packet including frequency policy information for each region for a cognitive radio communication, wherein the frequency policy information for each region is used based on a location of a terminal, and wherein the policy broadcasting packet further includes at least one of a preamble for matching synchronization with the policy broadcasting packet, a header of the frequency policy information, and power regulation situation information for each region or each service; and broadcasting the generated policy broadcasting packet to terminals of the each region including the terminal for the cognitive radio communication, wherein the policy broadcasting packet further includes a frequency allocation for the each region, a type of service provided on the allocated frequency, and a parameter indicating how to perform sensing by measuring specific features according to the type of service, for the terminals of the each region, and wherein the parameter includes information on a type of a sequence used in case of CDMA (Code Division Multiple Access), information on a bandwidth and a preamble in case of OFDM (Orthogonal Frequency Division Multiplexing), information on shift keying, and information on a cyclostationary characteristic.
