Version AoI Optimization under Power and General Distortion Constraints in Uplink NOMA

Gangadhar Karevvanavar, Rajshekhar V. Bhat, Nikolaos Pappas

The Version Age of Information (VAoI) quantifies information freshness by measuring the number of versions the receiver lags behind. This paper studies VAoI minimization in an -…

Clique-Based Deletion-Correcting Codes via Penalty-Guided Clique Search

Aniruddh Pandav, Rajshekhar V Bhat

We study the construction of -deletion-correcting binary codes by formulating the problem as a Maximum Clique Problem (MCP). In this formulation, vertices represent candidate co…

Non-Linear Precoding via Dirty Paper Coding for Near-Field Downlink MISO Communications

Akash Kulkarni, Rajshekhar V Bhat

In 6G systems, extremely large-scale antenna arrays operating at terahertz frequencies extend the near-field region to typical user distances from the base station, enabling near-f…

Age of Information Minimization in Goal-Oriented Communication with Processing and Cost of Actuation Error Constraints

Rishabh S. Pomaje, Jayanth S., Rajshekhar V. Bhat +1

We study a goal-oriented communication system in which a source monitors an environment that evolves as a discrete-time, two-state Markov chain. At each time slot, a controller dec…

Karush-Kuhn-Tucker Condition-Trained Neural Networks (KKT Nets)

Shreya Arvind, Rishabh Pomaje, Rajshekhar V Bhat

This paper presents a novel approach to solving convex optimization problems by leveraging the fact that, under certain regularity conditions, any set of primal or dual variables s…

Learning Short Codes for Fading Channels with No or Receiver-Only Channel State Information

Rishabh Sharad Pomaje, Rajshekhar V Bhat

In next-generation wireless networks, low latency often necessitates short-length codewords that either do not use channel state information (CSI) or rely solely on CSI at the rece…

Semantic Text Transmission via Prediction with Small Language Models: Cost-Similarity Trade-off

Bhavani A Madhabhavi, Gangadhar Karevvanavar, Rajshekhar V Bhat +1

We consider the communication of natural language text from a source to a destination over noiseless and character-erasure channels. We exploit language's inherent correlations and…

Version Age of Information Minimization over Fading Broadcast Channels

Gangadhar Karevvanavar, Hrishikesh Pable, Om Patil +2

We consider a base station (BS) that receives version update packets from multiple exogenous streams and broadcasts them to corresponding users over a fading broadcast channel usin…

Optimizing Reported Age of Information with Short Error Correction and Detection Codes

Sumanth S Raikar, Rajshekhar V Bhat

Timely sampling and fresh information delivery are important in 6G communications. This is achieved by encoding samples into short packets/codewords for transmission, with potentia…

An Encoder-Decoder Approach for Packing Circles

Akshay Kiran Jose, Gangadhar Karevvanavar, Rajshekhar V Bhat

The problem of packing smaller objects within a larger object has been of interest since decades. In these problems, in addition to the requirement that the smaller objects must li…

Importance-Aware Fresh Delivery of Versions over Energy Harvesting MACs

Gangadhar Karevvanavar, Rajshekhar V Bhat

We consider a scenario where multiple users, powered by energy harvesting, send version updates over a fading multiple access channel (MAC) to an access point (AP). Version updates…

Distortion Minimization with Age of Information and Cost Constraints

Jayanth S, Nikolaos Pappas, Rajshekhar V Bhat

We consider a source monitoring a stochastic process with a transmitter to transmit timely information through a wireless ON/OFF channel to a destination. We assume that once the s…

Maximization of Timely Throughput with Target Wake Time in IEEE 802.11ax

Rishabh Roy, Rajshekhar V Bhat, Preyas Hathi +2

In the IEEE 802.11ax standard, a mode of operation called target wake time (TWT) is introduced towards enabling deterministic scheduling in WLAN networks. In the TWT mode, a group…

Hybrid NOMA-TDMA for Multiple Access Channels with Non-Ideal Batteries and Circuit Cost

Rajshekhar Vishweshwar Bhat, Mehul Motani, Teng Joon Lim

We consider a multiple-access channel where the users are powered from batteries having non-negligible internal resistance. When power is drawn from the battery, a variable fractio…
