“…In [5], [6], the authors analyzed the signal-tointerference ratio (SIR) meta distribution for UL networks in the AR. In contrast, [7], [8] considered the FBR. [7] studied the average coding rate, rate outage probability, and coding rate meta-distribution for a downlink (DL) large-scale network.…”

With the expected proliferation of delay constrained applications, future communication technologies are pushed towards using short codes. The performance using short codes cannot be inferred through classical channel capacity analysis, which intrinsically assumes long codes and vanishing frame error rate (FER). This paper studies the performance of an uplink large-scale network in the finite blocklength regime. Bounds on the spatially averaged rate outage probability as well as the coding rate meta distribution are derived. The results reveal the exact achievable rate for a given blocklength and FER, and demonstrate the discrepancy between the actual network rate and idealistic classical channel capacity.

“…Many works [10]- [12] in this area are empirically based, aimed at determining what types of codes (e.g., LDPC and polar codes) are most suited for ultrareliable low-latency communications (URLLC). Another group of works analyze the tail behavior of the extreme events in ultrareliable communications, typically by means of the extreme value theory [13], [14] and the stochastic network calculus [2], [15]. For the system level design of ultrareliable communications, resource allocation has attracted considerable research interests, often in conjunction with newly emerging techniques of the next-generation networks, such as network slicing [16], non-orthogonal multiple access (NOMA) [17], [18], and massive multiple-input multiple-output (MIMO) [19].…”

Hybrid automatic repeat request (HARQ) is a key enabler for ultrareliable communications. This paper optimizes transmit power for the initial transmission and the subsequent retransmissions of HARQ with either incremental redundancy or Chase combining, aiming to minimize the expected energy consumption given the target outage probability and the target latency. The main challenge is due to the fact that the outage probability is a complicated function of the power variables which are nested in successive convolutions. The existing works mostly use a classic upper bound to approximate the outage probability by assuming unbounded transmit power, then convert the original problem to a geometric programming (GP) problem. In contrast, we propose a novel and much tighter upper bound by taking the practical power limit into consideration. The new bound and the resulting new GP method are further extended to a broader group of channel models with various fading, multiple antennas, and multiple receivers. As shown in simulations, the GP method based on the new bound significantly outperforms the existing strategies that either fix transmit power or optimize power by the classic bounding technique.Index Terms-Hybrid automatic repeat request (HARQ), incremental redundancy, Chase combining, ultrareliable communications, power control, energy consumption, new upper bound on outage probability, geometric programming (GP). I. INTRODUCTIONU LTRARELIABLE communications refer to transmitting data with a target outage probability lower than 10 −5 , as compared to the traditional cellular systems typically with an outage probability around 10 −2 [2]. This stringent performance standard is driven by a multitude of evolving applications of the Internet of Things (IoT), e.g., ultra highdefinition (UHD) video [3]. This paper seeks an energyefficient implementation of the hybrid automatic repeat request Manuscript accepted in IEEE Transactions on Wireless Communications.
