Mobile broadband data usage in Long Term Evolution (LTE) networks is growing exponentially and capacity constraint is becoming an issue. Heterogeneous network, WiFi offload, and acquisition of additional radio spectrum can be used to address this capacity constraint. Licensed spectrum, however, is limited and can be costly to obtain. This paper investigates deploying LTE on a license-exempt band as...
Opportunistic spectrum access, where cognitive radio devices detect available unused radio channels and exploit them for communication, avoiding collisions with existing users of the channels, is a central topic of research for future wireless communication. When each device has limited resources to sense which channels are available, the task becomes a reinforcement learning problem that has been...
