Coexistence of Wi-Fi and Cellular With Listen-Before-Talk in Unlicensed Spectrum
In this letter, we analyze the coexistence performance of Wi-Fi and cellular networks with different listen-before-talk (LBT) procedures in the unlicensed spectrum. For this analysis, the behavior ofExpand

Temporal Spectrum Sharing Based on Primary User Activity Prediction
In this paper we investigate the opportunistic spectrum access in temporal domain where a secondary user shares a radio channel with a primary user during the OFF period of the primary user. WeExpand

Temporal secondary access opportunities for WLAN in radar bands
In this paper we quantify the temporal opportunities for secondary access in radar bands. Secondary users are assumed to be WLANs which opportunistically access the radar spectrum. Each WLAN deviceExpand

Energy efficiency and sum rate tradeoffs for massive MIMO systems with underlaid device-to-device communications
In this paper, we investigate the coexistence of two technologies that have been put forward for the fifth generation (5G) of cellular networks, namely, network-assisted device-to-device (D2D)Expand
