  Owning abundant bandwidth resource, the Terahertz (0.1-10 THz) band is a
promising spectrum to support sixth-generation (6G) and beyond communications.
As the foundation of channel study in the spectrum, channel measurement is
ongoing in covering representative 6G communication scenarios and promising THz
frequency bands. In this paper, a wideband channel measurement in an L-shaped
university campus street is conducted at 306-321 GHz and 356-371 GHz. In
particular, ten line-of-sight (LoS) and eight non-line-of-sight (NLoS) points
are measured at the two frequency bands, respectively. In total, 6480 channel
impulse responses (CIRs) are obtained from the measurement, based on which
multi-path propagation in the L-shaped roadway in the THz band is elaborated to
identify major scatterers of walls, vehicles, etc. in the environment and their
impact on multi-path components (MPCs). Furthermore, outdoor THz channel
characteristics in the two frequency bands are analyzed, including path losses,
shadow fading, cluster parameters, delay spread and angular spread. In contrast
with the counterparts in the similar outdoor scenario at lower frequencies, the
results verify the sparsity of MPCs at THz frequencies and indicate smaller
power spreads in both temporal and spatial domains in the THz band.
