MmWave for Extended Reality: Open User Mobility Dataset, Characterisation, and Impact on Link Quality
arxiv(2024)
摘要
User mobility in extended reality (XR) can have a major impact on
millimeter-wave (mmWave) links and may require dedicated mitigation strategies
to ensure reliable connections and avoid outage. The available prior art has
predominantly focused on XR applications with constrained user mobility and
limited impact on mmWave channels. We have performed dedicated experiments to
extend the characterisation of relevant future XR use cases featuring a high
degree of user mobility. To this end, we have carried out a tailor-made
measurement campaign and conducted a characterisation of the collected tracking
data, including the approximation of the data using statistical distributions.
Moreover, we have provided an interpretation of the possible impact of the
recorded mobility on mmWave technology. The dataset is made publicly accessible
to provide a testing ground for wireless system design and to enable further XR
mobility modelling.
