Non-Orthogonal Multiple Access for Vehicular Communication [PDF]
2018 15th International Symposium on Wireless Communication Systems (ISWCS), 2018 In this paper, we establish a simple model for the exchange of messages in a vehicular network and we consider fundamental limits on the achievable data rate. For a vehicular network, the exchange of data with other nearby vehicles is particularly important for traffic safety, e.g.

Cache-Aided Non-Orthogonal Multiple Access [PDF]
2018 IEEE International Conference on Communications (ICC), 2018 In this paper, we propose a novel joint caching and non-orthogonal multiple access (NOMA) scheme to facilitate advanced downlink transmission for next generation cellular networks. In addition to reaping the conventional advantages of caching and NOMA transmission, the proposed cache-aided NOMA scheme also exploits cached data for interference ...
