Transmission Bundling for Wireless Device Interference Mitigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless devices proximate to antenna systems in cellular networks can interfere with communications, causing reception failures and requiring mitigation to ensure reliable data transmission.
Innovation Solution
Implementing transmission bundling for participant wireless devices, where uplink signals are bundled across multiple transmission time intervals to reduce interference and maintain communication reliability, by instructing devices to transmit redundant data over additional intervals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If transmission bundling is implemented for participant wireless devices, then communication reliability is improved and overhead is reduced, but device complexity increases due to coordinated control between access node and antenna system
Solution Approach 1:
The access node acts as an intermediary that receives interference indication from the antenna system and translates it into transmission bundling configuration for participant wireless devices. This mediator approach allows the antenna system to indirectly control participant device transmissions without direct complex interaction, improving reliability while managing complexity through the access node's coordination role.
Solution Approach 2:
The system implements feedback loops where the antenna system monitors uplink signals from non-participant devices, detects interference conditions, and sends indication messages to the access node. The access node then configures transmission bundling for participant devices based on this feedback, creating a closed-loop control system that adapts to interference conditions and maintains communication reliability.
2Reliability
If transmission bundling is used to mitigate interference from non-participant wireless devices, then reception failure rate decreases, but transmission time increases due to bundled transmission intervals
Solution Approach 1:
Transmission bundling applies partial action by selectively enabling bundled transmissions only for participant wireless devices in interference-prone scenarios, rather than all devices always. The access node configures bundling based on interference indication from the antenna system, applying the time-costly bundling mechanism only when and where needed to achieve reception success while minimizing overall transmission time loss.
Solution Approach 2:
The system dynamically adjusts transmission bundling configuration based on real-time interference conditions. The antenna system continuously monitors uplink signals and provides interference indication to the access node, which then dynamically configures transmission bundling parameters for participant devices. This dynamic adaptation allows the system to switch between bundled and non-bundled transmission modes, optimizing the trade-off between reception success rate and transmission time.

AI summary
Systems and methods are described for triggering transmission bundling for participant wireless devices of an antenna system. An uplink signal may be received at an access node from a wireless device in communication with the access node. It may be detected that the wireless device is proximate to an antenna system in communication with one or more participant wireless devices, wherein the antenna system does not comprise the access node. It may be then determined that transmission bundling should be triggered for the participant wireless device based on the detecting. And the participating wireless devices may be instructed to perform transmission bundling.
