While semantic communications can reduce traffic by prioritizing taskrelevant content, most existing approaches treat users independently and therefore overlook spatial redundancy among nearby devices’ observations. This paper proposes a semantic-aware multiple access scheme that exploits overlapping fields of view among vehicular users to reduce redundant uplink transmissions. We formulate a joint perception and transmission control problem in which users decide which image patches to transmit, when to transmit them, and over which channel, subject to communication constraints. To address the resulting complexity, we introduce a practical two-phase approach. First, nearby vehicles share selected observation patches over Vehicle-to-Vehicle (V2V) links to calculate inter-user spatial redundancy. Second, users transmit only semantically important, non-redundant patches to the base station, where observations can be reconstructed using the received patches and complementary views from neighboring vehicles. Simulation results in a dense urban vehicular scenario demonstrate that our approach improves the proportion of users who achieve high-fidelity reconstruction, highlighting the potential of semantic-aware multiple access for sustainable and resource-efficient 6G uplink systems.  \nIndex Terms—6G, Semantic-awareness, Semantic Communications, Resource Allocation, Multiple Access, Medium Access Control (MAC), Wireless Spectrum, generative AI, collaborative wireless networking, vehicular networks.  \nI. INTRODUCTION  \nThe phrase “Not all bits are equal” captures the guiding principle behind the semantic revolution in communications, where the significance of source bits is evaluated from the receiver’s perspective and leveraged to manage various network functionalities, including multiple access to the frequency spectrum [1],[2] . Recent advancements in the Artificial Intelligence (AI) domain have facilitated the extraction of non-linear patterns from data, enabling the identification of semantic segments (meaningful data regions) and the prioritization of their transmission according to importance to the downstream task [3] . For instance, in a vehicular uplink streaming service with front-view cameras mounted on vehicles, a safety application may focus exclusively on segments that contain pedestrians, pets, and cyclists, whereas a navigation system  \nmay prioritize road and traffic sign information. For each of these applications, prioritized segment transmission can be realized within the framework of semantic communications [4] .  \nNonetheless, most existing literature focuses on either single-user settings or scenarios involving multiple independent users, where the significance of each bit is only relevant within an individual user’s context [5]–[9] . For instance, Devoto et al. [5] introduce a transformer-based framework that adaptively identifies and transmits only the visual tokens most relevant to the target task for edge inference, while dynamically responding to channel fluctuations.
