PUSCH Muting Pattern Configuration for Cross-Link Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems fail to consider Physical Uplink Shared Channel (PUSCH) resource mapping types when configuring uplink resource muting patterns, leading to improper configuration and degraded system performance.
Innovation Solution
Configure uplink resource muting patterns based on different PUSCH resource mapping types (Type A and Type B) to ensure appropriate muting patterns are applied, allowing muted resources to be used for cross-link interference handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If uplink resource muting patterns are configured without considering PUSCH resource mapping types, then configuration simplicity is maintained, but system performance is degraded
Solution Approach 1:
The patent applies different uplink resource muting patterns specifically tailored to different PUSCH resource mapping types (Type A and Type B). Instead of using a single uniform configuration, the system configures muting patterns that are locally optimized for each mapping type, considering their distinct characteristics in terms of resource allocation and transmission behavior.
Solution Approach 2:
The patent introduces dynamic adaptation by selecting muting patterns based on the specific PUSCH resource mapping type being used. The configuration is not static but adapts to the operational context, allowing the system to switch between different muting patterns depending on which mapping type is active, thereby optimizing performance for each scenario.
2Loss of information
If a single uplink resource muting pattern is used for all PUSCH resource mapping types, then configuration overhead is reduced, but resource utilization efficiency is degraded
Solution Approach 1:
The patent configures distinct uplink resource muting patterns for Type A and Type B PUSCH resource mapping types, where each pattern is optimized for the specific characteristics of its target mapping type. This local optimization ensures that resources are muted in a manner that is appropriate for each mapping type's structure and behavior, thereby improving overall resource utilization efficiency.
Solution Approach 2:
The patent changes the parameters of the muting pattern configuration based on the PUSCH resource mapping type. Different mapping types have different resource allocation parameters, and the muting patterns are adjusted to match these parameters, ensuring optimal resource utilization for each type while maintaining efficient configuration management.
3Ease of manufacture
If uplink resource muting patterns are configured without considering PUSCH resource mapping types, then implementation simplicity is maintained, but cross-link interference handling is degraded
Solution Approach 1:
The patent applies specific uplink resource muting patterns that are tailored to each PUSCH resource mapping type to effectively handle cross-link interference. By considering the distinct characteristics of Type A and Type B mapping types, the system can mute resources in a manner that specifically addresses the interference patterns associated with each type, thereby improving cross-link interference handling.
Solution Approach 2:
The patent converts the potential harm of cross-link interference into a benefit by using the muting patterns to create protected resource elements. These muted resources are specifically designed to prevent interference, and the pattern configuration ensures that resources susceptible to cross-link interference are appropriately muted, thereby transforming the interference problem into a controlled and managed aspect of the system.
