Spectrum sensing and non-orthogonal multiple access based massive grant-free random access scheme

A massive grant-free random access scheme based on spectrum sensing provided by cognitive radio (CR) and non-orthogonal multiple access (NOMA) was proposed for massive machine type communication scenarios. Firstly, a three-step grant-free random access protocol based on CR-NOMA was put up, which cou...
