HARQ Buffer Management: An Information-Theoretic View

open access: yes, 2015
A key practical constraint on the design of Hybrid automatic repeat request (HARQ) schemes is the size of the on-chip buffer that is available at the receiver to store previously received packets. In fact, in modern wireless standards such as LTE and LTE-

Minimizing Age of Information in Slotted ALOHA With Short-Packet Communications

open access: yesIEEE Access
Age of information (AoI) has emerged as a novel metric for quantifying the freshness of information at the receiver side. This metric has found numerous applications in real-time monitoring and control systems where stale information may lead to critical

Feedback Capacity of the Compound Channel

open access: yes, 2007
In this work we find the capacity of a compound finite-state channel with time-invariant deterministic feedback. The model we consider involves the use of fixed length block codes. Our achievability result includes a proof of the existence of a universal

On Channel Reciprocity to Activate Uplink Channel Training for Downlink Wireless Transmission in Tactile Internet Applications

open access: yes, 2018
We determine, for the first time, the requirement on channel reciprocity to activate uplink channel training, instead of downlink channel training, to achieve a higher data rate for the downlink transmission from a multi-antenna base station to a single ...

Power Allocation for Finite-Blocklength IR-HARQ

open access: yesIEEE Communications Letters
This letter concerns the power allocation across the multiple transmission rounds under the Incremental Redundancy Hybrid Automatic Repeat reQuest (IR-HARQ) policy, in pursuit of an energy-efficient way of fulfilling the outage probability target in the finite-blocklength regime.
