Achievable Rate Analysis of Opportunistic Transmission in Bursty Interference Networks

In this letter, we consider the K-user bursty fading interference channel, where each user transmits data intermittently with a certain probability under the local channel state information assumption. In particular, we consider three different transmission techniques with fixed power: random transmission (RT), opportunistic transmission-based on generating interference (OT-1), and opportunistic transmission based on desired channel gain (OT-2). We mathematically analyze the average achievable rates of the three transmission techniques, which is the first theoretical result to the best our knowledge. The analysis is validated via extensive computer simulations. It is shown that the opportunistic transmission techniques (OT-1 and OT-2) result in better performance in terms of the achievable rate compared with the RT as well as the conventional non-bursty transmission technique.
