This paper presents a novel cross-layer scheme for video transmission of streams with heterogeneous characteristics over LTE-based wireless systems. The proposed cross-layer scheme is organized by taking into account parameters from the Application layer (I-frames and P-frames), MAC Layer (scheduling packets according to their importance) and Physical Layer (linear precoding). All these parameters are considered within a novel resource allocation algorithm, which guarantees a weighted rate balancing across users, which is proportional to the bit rate of each video stream. Simulation results show that the proposed cross layer scheme can efficiently support video delivery both in terms of individual video quality and system overall performance.
