With an increasing concern on energy consumption in communication systems, we propose the use of two-mode transceiver circuitry to improve a system’s energy efficiency so the system is capable of switching between idle and transmission modes. In this letter, we develop a simple energy efficiency analytical model based on this circuitry. Simulation results show that our model is highly accurate in...
In order to meet the explosive traffic demand, the capacity of Long Term Evolution(LTE) system needs to be further expanded, and one choice is to integrate unlicensed carrier into the overall LTE system. However, unlicensed band might be shared by other communication systems like Wi-Fi and radar, so the available bandwidth for each user could not be guaranteed. We propose a carrier aggregation resource...
