Joint Beamforming and Resource Allocation Design for STARS-Assisted OFDMA ISCC Network

Due to the favorable features of full-space coverage and extra degree-of-freedom in design, the simultaneously transmitting and reflecting surface (STARS) technology is expected to empower the integrated sensing, communication, and computing (ISCC) network in next-generation. In light of this, a novel STARS-assisted orthogonal frequency division multiple access (OFDMA) ISCC network is proposed for wide-bandwidth applications, where the communication and computing (C&C) weighted sum-rate is maximized while fulfilling the fundamental sensing requirement via jointly designing the ISCC beamforming, the subcarrier allocation, as well as the transmission and reflection beamforming of the STARS. The formulated challenging problem is handled effectively by an alternating optimization-based algorithm and its effectiveness is validated experimentally. Simulation results indicate that our proposed scheme outperforms other baselines with substantial performance gains. Additionally, numerical results highlight a crucial performance trade-off among the multi-function of the considered ISCC network, offering valuable guidelines for practical applications.
