| Research Abstract |
This project researched the channel assignments which lead to the highest possible communication connectivity on he condition that the total number of required channels is constant. Several channel assignment schemes have been roposed depending on repacking approaches; non- repacking, always repacking, and repacking on demand. In this project, these schemes are evaluated primarily with the prospect of attaining the highest communication connectivity. The evaluations quantitatively indicate that repacking on demand may significantly outperform the others under the condition that not only the number of prepared micro-cell channels remains constant, but also the total number prepared of both micro-cell and macro-cell channels remains constant as well.
