  In this work, we consider the 3D defocusing energy-critical nonlinear
Schr\"odinger equation
  $i\partial_t u+\Delta u =|u|^4 u,\quad (t,x)\in \mathbb{R}\times
\mathbb{R}^3$.
  Applying the outgoing and incoming decomposition presented in the recent work
\cite{BECEANU-DENG-SOFFER-WU-2021}, we prove that any radial function $f$ with
$\chi_{\leq1}f\in H^1$ and $\chi_{\geq1}f\in H^{s_0}$ with $\frac{5}{6}<s_0<1$,
there exists an outgoing component $f_+$ (or incoming component $f_-$) of $f$,
such that when the initial data is $f_+$, then the corresponding solution is
globally well-posed and scatters forward in time; when the initial data is
$f_-$, then the corresponding solution is globally well-posed and scatters
backward in time.
