Low latency communication for Internet of Things

With the rise of IoT and social media, the major traffic flows in the future wireless network is not conventional phone traffic anymore. These rising traffic flows have stricter requirements on the latency performance and therefore need different resource utilization approaches. To resolve the resource utilization scheme of the upcoming new traffic flows, we envision the design of the open-loop communication for the devices. With the open-loop communication, all the data packets are directly transmitted without the need on neither feedback nor control signals and therefore increases the spectrum efficiency and reduce the latency. To be fully compatible with the current closed-loop cellular operations to maximize operating benefits, an autonomous communication scheme is further developed to adapt all communication scenarios in the heterogeneous wireless networks.
