In 2012, he chaired the 2012 Wireless Communications, which was held July 3-5, 2012 in Banff, Canada. Currently, he serves as an Editor for IEEE Communications Letters, IEEE Transactions on Wireless Communications, an Associate Editor for IEEE Access, and a Guest Editor for a special issue of IEEE Journal on Selected Areas in Communications on optical wireless communications. Dr. Cheng is also a Senior Member of IEEE.

Dr. Cheng was the recipient of numerous scholarships during his undergraduate and graduate studies, which included a President Scholarship from the University of Victoria and a postgraduate scholarship from the Natural Sciences and Engineering Research Council of Canada (NSERC). He was also a winner of the 2002 NSERC Postdoctoral Fellowship competition.
