Cooperative communications is a relevant technol- ogy for modern networks. The association of this technology together with efficient resource allocation have the potential to achieve performance gains in terms of coverage, spectral efficiency and satisfaction. Previous works have studied the max- imization of spectral efficiency without satisfaction constraints for cooperative networks. On the other hand, maximization of user satisfaction have been studied for non cooperative networks. In this work we propose a new resource allocation problem for maximizing the number of satisfied users in a cooperative system. This problem is optimally solved at the cost of a high computational complexity, and suboptimally solved with reduced complexity and energy efficiency gains.
