- 초록
- For low latency communications, we propose an enhanced random access scheme that avoids random access retrials from the beginning of the random access due to the expiry of a random access response window. The proposed random access scheme exploits multiple transmissions of random access preambles and random access responses. We also provide model and analysis of random access latency with expected delay and the probability of preamble collision. Our numerical results show that the proposed scheme provides lower latency.
