摘要
Semantic communication (SC) has emerged as a novel communication paradigm for enhancing transmission efficiency in wireless networks by prioritizing data semantics over raw bits. Meanwhile, mobile delay-sensitive users demand strict low-latency transmissions for critical tasks such as emergency response. Supporting both user types under limited resources is challenging. This paper proposes a joint resource allocation framework that integrates time-slot allocation and relay assignment to serve semantic- and delay-sensitive users simultaneously. The formulated problem is hard to solve optimally. We develop a Joint Matching, Time Slot, and Relay Allocation Algorithm (JMTRA) that combines stable matching, knapsack-based scheduling, and linear-programming-based relay selection to find a suboptimal solution. Simulation results demonstrate that our approach improves semantic performance while meeting delay constraints.
