Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The existing wireless communication systems face increased signaling overhead due to iterative and periodic signaling of dynamic configuration information between network nodes and repeater devices, leading to reduced data throughput and increased data transfer latencies.

Innovation Solution

A smart repeater device is introduced, which receives a detection configuration from a network node to autonomously detect transmissions associated with user equipment (UE), thereby reducing signaling overhead. The detection configuration indicates parameters such as air interface resources and UE identifiers, enabling the repeater device to detect and relay transmissions efficiently.
