In the future smart transportation sys-tem,reliable vehicle-to-infrastructure(V2I)commu-nication is very important to ensure vehicle driving safety and to improve vehicle driving efficiency.In this paper,V2I channel measurements at 5.92 GHz are conducted in typical urban and highway scenarios.The frequency and bandwidth of transmission,as well as the deployment of the RSU(roadside unit)and the OBU(on board unit),are selected by considering the recommendation proposed by 3GPP TR 36.885.Then,based on the measured data,the key channel charac-teristic parameters of the V2I channel are extracted,including path loss,root-mean-square delay spread,stationarity distance,and Doppler spread,etc.Also,the statistical characteristics of the parameters,includ-ing time-varying and Doppler characteristics,are in-vestigated and characterized.The work in this paper helps researchers design technology and communica-tion systems in similar scenarios.

In this paper,we focus on the pilot-assisted transmission design for downlink URLLC over non-reciprocal channels,in which the multi-antenna con-troller sends mission-critical data signals to a single-antenna actuator.In this system,the prior knowledge of
A joint Doppler shift and channel estima-tion method for the millimeter-wave communication system of an unmanned aerial vehicle(UAV)equipped with a large-scale uniform linear antenna(ULA)array has been proposed.Since Doppler shift induces in-tercarrier in
The sub-6G band is too crowded to accom-modate higher data rate,while the millimeter wave(mmWave)bands have abundant spectrum resources and massive MIMO can provide high spectral and en-ergy efficiency.Therefore,the combination of the two,namely mmWave-MI
Non-orthogonal multiple access(NOMA)has been integrated in millimeter-wave(mmWave)Massive MIMO systems to further enhance the spec-trum efficiency,but NOMA has not been fully consid-ered in lens mmWave systems.The fusion of these two technologies requires
