A simple model for DVB and LTE cooperation

International audienceThe link budget of a Digital Video Broadcasting (DVB) handheld receiver is weak compared to fixed receivers because of its configurational disadvantages. In our proposition, the LTE network helps in resolving the DVB handheld outage by retransmitting the missing DVB sequences to the handheld receivers. Our model analyzes the load over the LTE access network due to the retransmission of the missing sequences of a DVB transmission.We assume a low-definition DVB TV service to be received by each of the handheld terminals. It was found that along with achieving a correct DVB flow using LTE network, it is also possible to save a fair amount of DVB transmission power for a reasonable load over the LTE network. We analyze our model for several different Inter-Site Distances (ISD) among eNodeBs. It is observed that with the smaller ISDs it is possible to further reduce the load over the LTE network
