Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If resource muting patterns are applied to improve CLI measurement accuracy, then measurement precision is improved, but device complexity increases due to unclear or undefined muting patterns
Solution Approach 1:
The resource muting pattern is segmented into specific time domain locations (first one or more symbols) within a time interval, allowing precise identification of muting resources. This segmentation enables clear differentiation between muted and non-muted resources, improving CLI measurement accuracy while reducing complexity through structured organization.
Solution Approach 2:
The patent applies resource muting in advance during specific symbols within a time interval before CLI measurements are performed. By pre-defining and applying muting patterns beforehand, the system ensures that interference is eliminated at the source, improving measurement accuracy without requiring complex real-time processing.
2Object-affected harmful factors
If resource muting is applied to reduce interference, then harmful factors are reduced, but loss of time occurs due to increased latency
Solution Approach 1:
The resource muting is applied periodically during specific symbols within time intervals according to a defined pattern. This periodic application ensures that muting occurs only when necessary for CLI measurements, reducing interference impact while minimizing time loss by avoiding continuous muting that would increase latency.
Solution Approach 2:
The patent applies resource muting partially, only during the first one or more symbols within a time interval, rather than continuously. This partial application is sufficient to eliminate interference during critical measurement periods while preserving resource availability for other transmissions, thereby reducing latency.
3Measurement precision
If resource muting pattern is defined to improve CLI measurement, then measurement precision is improved, but productivity decreases due to decreased throughput
Solution Approach 1:
The time interval is segmented into specific symbols for muting and other symbols for normal transmission. This segmentation allows CLI measurements to be performed accurately during muted symbols while maintaining high throughput during non-muted symbols, resolving the contradiction between measurement precision and productivity.
Solution Approach 2:
The resource muting is applied partially during only the first one or more symbols within a time interval, rather than throughout the entire interval. This partial muting provides sufficient interference reduction for accurate CLI measurements while preserving the majority of resources for data transmission, thereby maintaining high throughput.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information indicating a resource muting pattern, wherein the resource muting pattern is associated with a first one or more symbols, within a time interval associated with a set of resources, during which the resource muting pattern is to be applied. The UE may transmit one or more signals in one or more available resources, from the set of resources, in accordance with the resource muting pattern. Numerous other aspects are described.
