In this paper, a novel cross-layer scheme is presented for video transmission over LTE-based wireless systems. The proposed cross-layer scheme takes into account parameters from the application layer (I-based versus P-based packets), MAC Layer (Scheduling packets according to their importance) and Physical Layer (Linear Precoding). All these parameters are considered within a novel resource allocation algorithm with transmission rate constraints suitable for video applications. Simulations results have shown that the proposed cross-layer scheme performs better in terms of system throughput and perceived video quality against similar cross-layer schemes.
