In the emerging sixth generation(6G) communication network, energy har-vesting (EH) is a promising technology to achieve the unlimited energy supply and hence makes the wireless communication systems self-sustainable in terms of energy. However,in practice, the efficiency of energy harvesting is often low due to the limited device capabil-ity. In this paper, we formulate three types of different EH architectures, i.e., the harvest-use architecture, the harvest-store-use architecture,and the harvest-use-store architecture from the perspective of energy storage efficiency. We propose resource allocation schemes to jointly design the sensor power and duty-cycle via an alternating optimization algorithm under the above EH architectures, in both simultaneous and non-simultaneous harvesting and utili-zation models, aiming at achieving a higher throughput and energy efficiency. Non-ideal circuit power is also considered. Numerical results show that our proposed schemes under EH architectures outperform the existing clas-sic continuous transmission schemes.
