  • Recent measurements show that there are abundant spectrum opportunities across the licensed cellular bands, over which the relay stations (RSs) are widely employed for both coverage extension and throughput improvement. However, current efforts in cognitive radios focus on exploiting spectrum holes over the licensed direct transmission links. To exploit new spectrum opportunities over the licensed relay assisted transmission links, we propose a novel two-phase joint sensing and transmission… CONTINUE READING
