Analysis of Non-Pilot Interference on Link Adaptation and Latency in Cellular Networks
Published: Apr 1, 2019
Abstract
Modern wireless standards such as Long-Term Evolution (LTE) and 5G New Radio (5G NR) use pilot-aided SINR estimates to adapt the modulation and coding scheme (MCS) and transmission mode of data blocks, to fully utilize the channel capacity. However, when interference is localized exclusively on non-pilot resources, pilot-aided SINR estimates become inaccurate. We show that this leads to congestion due to retransmissions, and in the worst case,...
