Sub-Chain Beam for mmWave Devices: A Trade-off between Power Saving and Beam Correspondence
Jianhua Mo, Daehee Park, Boon Loong Ng +4
Beam correspondence, or downlink-uplink (DL-UL) beam reciprocity, refers to the assumption that the best beams in the DL are also the best beams in the UL. This is an important ass…
Online Learning for Position-Aided Millimeter Wave Beam Training
Vutha Va, Takayuki Shimizu, Gaurav Bansal +1
Accurate beam alignment is essential for beam-based millimeter wave communications. Conventional beam sweeping solutions often have large overhead, which is unacceptable for mobile…
Inverse Multipath Fingerprinting for Millimeter Wave V2I Beam Alignment
Vutha Va, Junil Choi, Takayuki Shimizu +2
Efficient beam alignment is a crucial component in millimeter wave systems with analog beamforming, especially in fast-changing vehicular settings. This paper proposes a position-a…
Millimeter Wave communication with out-of-band information
Nuria González-Prelcic, Anum Ali, Vutha Va +1
Configuring the antenna arrays is the main source of overhead in millimeter wave (mmWave) communication systems. In high mobility scenarios, the problem is exacerbated, as achievin…
Millimeter Wave Vehicular Communication to Support Massive Automotive Sensing
Junil Choi, Vutha Va, Nuria Gonzalez-Prelcic +3
As driving becomes more automated, vehicles are being equipped with more sensors generating even higher data rates. Radars (RAdio Detection and Ranging) are used for object detecti…
The Impact of Beamwidth on Temporal Channel Variation in Vehicular Channels and its Implications
Vutha Va, Junil Choi, Robert W. Heath
Millimeter wave (mmWave) has great potential in realizing high data rate thanks to the large spectral channels. It is considered as a key technology for the fifth generation wirele…
