Query: A Preamble Collision Resolution Scheme via Tagged Preambles for Cellular
  IoT/M2M Communications   In this paper, we propose a preamble (PA) collision resolution (PACR) scheme
based on multiple timing advance (TA) values captured via tagged PAs. In the
proposed PACR scheme, tags are embedded in random access (RA) PAs and multiple
TA values are captured for a single detected PA during a tag detection
procedure. The proposed PACR scheme significantly improves RA success
probability for stationary machine nodes since the nodes using collided PAs can
successfully complete the corresponding RAs using exclusive data resource
blocks.
