  In this paper, we investigate the issue of integrated sensing, computation
and communication (SCC) in beyond fifth-generation (B5G) cellular internet of
things (IoT) networks. According to the characteristics of B5G cellular IoT, a
comprehensive design framework integrating SCC is put forward for massive IoT.
For sensing, highly accurate sensed information at IoT devices are sent to the
base station (BS) by using non-orthogonal communication over wireless multiple
access channels. Meanwhile, for computation, a novel technique, namely
over-the-air computation (AirComp), is adopted to substantially reduce the
latency of massive data aggregation via exploiting the superposition property
of wireless multiple access channels. To coordinate the co-channel interference
for enhancing the overall performance of B5G cellular IoT integrating SCC, two
joint beamforming design algorithms are proposed from the perspectives of the
computation error minimization and the weighted sum-rate maximization,
respectively. Finally, extensive simulation results validate the effectiveness
of the proposed algorithms for B5G cellular IoT over the baseline ones.
