Extensive research on heavy-ion collisions at the Large Hadron Collider (LHC) and Relativistic Heavy Ion Collider (RHIC) has helped us produce and study the properties of quark-gluon plasma (QGP). Recent investigations hint towards the possible formation of QGP-droplets even in small collision systems such as high-multiplicity pp collisions. Oxygen-Oxygen (O+O) collisions are expected in the forthcoming RUN3 at the LHC. This will provide an essential and timely opportunity to investigate the effects of high-multiplicity pp and p+Pb collisions with similar system sizes. In this work, we implement harmonic oscillator and Woods-Saxon type density profiles for the oxygen nucleus. Also, an alpha-cluster tetrahedral structure for the oxygen nucleus is studied. We report the charged-particle multiplicity, transverse mass, Bjorken energy density, squared speed of sound, and the kinetic freezeout parameters in O+O collisions at $\sqrt{s_{\rm NN}}$ = 7 TeV using a multiphase transport model.
