Solution Overview
Problem
Existing wireless communication systems face inefficiencies in processing in-order, out-of-order, and overlapping data transmissions, leading to increased latency, misalignment between base stations and wireless devices, and higher overhead and retransmissions.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a wireless device processes data in the conventional manner without resource group configuration, then the device complexity is low, but the channel processing efficiency deteriorates and latency increases
Solution Approach 1:
The patent segments communication resources into multiple resource groups (first resource group, second resource group, etc.) with distinct characteristics. Each resource group can be independently configured and processed, allowing the wireless device to handle different data types (in-order, out-of-order, overlapping) through appropriate resource groups. This segmentation improves channel processing efficiency by enabling parallel and optimized processing paths while maintaining manageable device complexity through structured organization.
2Productivity
If a wireless device processes out-of-order and overlapping data transmissions, then the system throughput is improved, but the misalignment between base station and wireless device increases
Solution Approach 1:
The patent introduces priority indications as a configurable parameter that can be included or excluded from downlink transmissions based on the data type. For in-order data, no priority indication is needed (simpler processing). For out-of-order and overlapping data, priority indications are included to enable proper ordering and processing. This parameter change approach allows the system to achieve high throughput for complex data types while maintaining alignment and reliability through appropriate use of priority information.
3Measurement precision
If priority indications are included in all data transmissions, then the data processing accuracy is improved, but the overhead increases
Solution Approach 1:
The patent applies priority indications selectively rather than universally. Priority indications are included only in downlink transmissions containing out-of-order or overlapping data where they are needed for accurate processing. For standard in-order data transmissions, priority indications are omitted. This local quality approach ensures data processing accuracy is improved only where necessary, while minimizing overhead in cases where simple sequential processing suffices.
4Adaptability or versatility
If a wireless device is configured with multiple resource groups, then the adaptability to different data types is improved, but the device complexity increases
Solution Approach 1:
The patent designs resource groups with universal characteristics that can handle multiple data types through a unified framework. Each resource group is configured with parameters (such as priority handling, ordering requirements) that can be adjusted to accommodate in-order, out-of-order, and overlapping data. This multi-functionality approach enables the wireless device to adapt to different data types using a standardized resource group structure, avoiding the need for completely separate processing paths for each data type and thus limiting the increase in device complexity.
Data Source
AI summary
A wireless device comprises processor(s) and memory storing instructions that, when executed by the processor(s), cause the wireless device to: receive, via a channel associated with a first control resource set (CORESET) in a first CORESET group, a first message indicating a first scheduled transmission of a first downlink signal, and after receiving the first message, receive, via a channel associated with a second CORESET in a second CORESET group different from the first CORESET group, a second message indicating a second scheduled transmission of a second downlink signal. The wireless device is to receive the second scheduled transmission of the second downlink signal before an end of the first scheduled transmission of the first downlink signal
