How to efficiently use the limited wireless bandwidth is of paramount important in the radio wireless network area. To use the wireless bandwidth in an efficiently way, one can consider a pricing model to improve users received video layers. In this paper, the users are divided into three classes. For different class users, they pay different price and enjoy different QoS. In a pricing model, more video layers are allocated to those users who pay a higher price. We propose a Pricing Class based Resource Allocation Scheme (PCRAS) that considers the price of multicast group and uses channel quality indicator to compute resource allocation priority to dispatch resource blocks efficiently. Experimental results shows that the proposed scheme can increase users' received video layers and users between different classes will receive different level of services. In comparison to other existing scheduling schemes, the proposed scheme can improve users' video experience.
