• Cooperative spectrum sensing can detect the primary signal more reliably via exploiting spatial diversity, which usually requires extra common reporting channel for cognitive radios to exchange local sensing decision. In this letter, we propose a conservative cooperative spectrum sensing scheme, which can utilize the licensed channel for transmitting local sensing decision with limited interference to primary users. The new scheme can save the common reporting channel without sacrificing ROC performance and mitigate total interference probability compared with conventional cooperative sensing scheme.
