In this collaboration between Huawei Technologies and IMDEA Networks, the project partners explore the potential of using low frequency bands to infer the channel characteristics of high frequency millimeter-wave bands. The inferred channel characteristics can support the network in terms of beam tracking, angle of arrival estimation, and location information. This results in improved performance in the millimeter-wave band since these techniques reduce the control overhead required to operate the network. The project also includes an experimental evaluation to verify that the developed mechanisms and algorithms work not only in theory but also in practical real-world wireless networking environments.
