— In cellular networks, relays and/or mobiles can cooperate to improve the overall system performance. For example, once the transmission from a base station with multiple antenn...
In cellular systems, confidentiality of uplink transmission with respect to eavesdropping terminals can be ensured by creating intentional interference via scheduling of concurren...
—We venture beyond the “listen-before-talk” strategy that is common in many traditional cognitive radio access schemes. We exploit the bi-directional nature of most primary c...
Traditionally, the routing problem is addressed at the network layer, an approach that has been extended to the wireless realm. In wireless multihop networks, however, strict laye...
—Coordinated multi-point transmission/reception (CoMP), in which base stations (BSs) cooperate during the downlink, has been identified as a tool for improving user rates and mi...
