Carrier Bundling Indication in Wireless DCI
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently managing and combining information across multiple carriers, which can lead to suboptimal user experience and network performance.
Innovation Solution
The proposed solution involves a wireless communication device and method that receive downlink control information (DCI) indicating whether information scheduled for transmission on one carrier is duplicable or combinable with information on another carrier. The device then combines these information streams accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If information is transmitted on multiple carriers without bundling indication, then carrier diversity is utilized, but combining efficiency deteriorates
Solution Approach 1:
The patent introduces downlink control information (DCI) as an intermediary carrier that conveys bundling indication between the network and user equipment. This DCI explicitly indicates whether bundling should be applied across carriers, enabling the receiver to correctly combine information from multiple carriers while maintaining transmission reliability.
Solution Approach 2:
The patent implements dynamic bundling indication through DCI that can adaptively signal whether bundling is applied. This allows the system to dynamically switch between bundled and non-bundled transmission modes based on channel conditions and traffic requirements, optimizing both reliability and combining efficiency in real-time.
2Reliability
If bundling is applied across all carriers, then signal quality improves, but system complexity increases
Solution Approach 1:
The patent enables selective bundling application where bundling can be applied to specific carriers or specific information types based on DCI indication, rather than forcing uniform bundling across all carriers. This localized approach improves signal quality where needed while avoiding unnecessary complexity in other parts of the system.
Solution Approach 2:
The patent segments the bundling decision into carrier-specific or information-type-specific applications through DCI indication. This segmentation allows different bundling strategies to be applied to different carriers independently, improving overall system efficiency without requiring complex unified processing across all carriers.
3Adaptability or versatility
If separate processing is done for each carrier, then carrier independence is maintained, but network efficiency deteriorates
Solution Approach 1:
The patent merges the processing of information across multiple carriers when bundling is indicated through DCI. By combining information from multiple carriers in a coordinated manner rather than processing them completely independently, the system achieves better network efficiency while maintaining the flexibility to process carriers separately when bundling is not applied.

AI summary
Various aspects relate to indicating bundling across carriers (e.g., across cells). In some aspects, bundling may involve sending information sent over multiple carriers (e.g., information sent from or to multiple cells) where the information sent over the carriers is combinable at a receiver. For example, a communication device may send the same set of information (e.g., transport blocks with the same content) via multiple carriers, send different redundancy versions of a set of information via different carriers, send information via different beams on different carriers, or send information using a combination of these techniques. The disclosure relates in some aspects to indicating whether bundling is applied across carriers. For example, downlink control information (DCI) that schedules transmissions on multiple carriers (e.g., multiple component carriers) may include an indication of whether bundling is applied across all or a subset of the scheduled carriers.
