Coverage and Rate of Downlink Sequence Transmissions with Reliability Guarantees

Research output: Research - peer-reviewJournal article

Abstract

Real-time distributed control is a promising application of 5G in which communication links should satisfy certain reliability guarantees. In this letter, we derive closed-form maximum average rate when a device (e.g. industrial machine) downloads a sequence of n operational commands through cellular connection, while guaranteeing a certain coverage for all n messages. The result is based on novel closed-form n- successive coverage bounds. The proposed lower bound provides a simple approximation that is increasingly accurate in the high reliability region. For moderate coverage, a linear combination of the proposed bounds enables deriving a tractable approximation. Both techniques can be utilized for calculating the maximum average rate with and without using adaptive modulation and coding (AMC).
