Current wireless networks have no knowledge on the type and characteristics of the specific mobile services and contents they are providing (they are agnostic). On the other hand, associated to richer content and more advanced devices, improvement of Quality of Experience (QoE) levels perceived by each user looks as one of the main goals of the different actors in the telecommunication's ecosystem. In this respect, network awareness of the transferred content types and their quality requirements can be important to deliver them fulfilling user requirements while optimizing the utilization of network resources. In this paper, we explore the effect of including semantic knowledge in the radio resource management (RRM) schemes of cellular systems as a way to reach this balance for video streaming service. To make this possible, we propose a number of semantic-aware RRM schemes using information about the video playback's current status, and investigate their performances based on the reduction of the total time of interruptions (TTI) perceived by users when a video streaming content is played. The achieved results are compared to those of the standard agnostic scheme implemented in the cellular networks. The outcomes show that incorporating semantic-aware RRM schemes, more users can receive the content provided by a network within a tolerable level of TTI, while the number of users receiving High Definition (HD) videos can be increased, which in general terms might reduce the investment in infrastructure to fulfill users' requirements.
