CLI Measurement Reporting with Differential Quantization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cross-link interference (CLI) in wireless communication systems increases power consumption and processing resource use, leading to higher latency and network overhead, particularly in network-side subband full duplex (SBFD) operations.
Innovation Solution
Configuring resources for reporting CLI measurements with a dynamic maximum quantity of measurements and bits, allowing for differential value quantization to conserve power and processing resources at user equipment (UE) and improve measurement accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If CLI measurements are reported with high precision and quantity, then measurement accuracy is improved, but power consumption and processing resource use increase
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the quantity of bits used for quantization based on CLI measurement conditions. When CLI interference is high, more bits are allocated to maintain measurement accuracy; when CLI is low, fewer bits are used to reduce power consumption and processing resources. This adaptive parameter adjustment resolves the contradiction between measurement precision and energy consumption.
Solution Approach 2:
The patent implements dynamics by making the maximum quantity of measurements and bits a dynamic configuration rather than a fixed value. The network can adjust these parameters in real-time based on network conditions, UE capabilities, and CLI characteristics. This dynamic approach allows the system to optimize the balance between measurement accuracy and resource consumption adaptively.
2Measurement precision
If CLI measurements are reported with high precision and quantity, then measurement accuracy is improved, but network overhead increases
Solution Approach 1:
The patent changes the parameter of quantization bits dynamically based on network conditions and CLI measurement requirements. By adjusting the number of bits allocated for CLI reporting, the system can maintain necessary measurement accuracy while minimizing the amount of data transmitted, thus reducing network overhead. This parameter adaptation resolves the contradiction between measurement precision and quantity of transmitted data.
3Reliability
If maximum quantity of measurements is increased, then CLI detection capability is improved, but processing resource use at UE increases
Solution Approach 1:
The patent makes the maximum quantity of measurements a dynamic parameter that can be adjusted based on network conditions and UE capabilities. When CLI interference is severe, the system increases the quantity of measurements to improve detection capability; when conditions are favorable, it reduces the quantity to lower processing resource consumption. This dynamic adjustment resolves the contradiction between reliability and device complexity.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration associated with a set of cross-link interference (CLI) resources. The UE may perform measurements using the set of CLI resources to determine a set of CLI measurements. The UE may transmit a report for a subset, of the set of CLI measurements, based at least in part on a maximum quantity of measurements. The report may include: one or more identifiers of a subset, of the set of CLI resources, corresponding to the subset of CLI measurements; a first measurement in the subset of CLI measurements using an absolute value quantized to a first quantity of bits; and remaining measurements in the subset of CLI measurements using differential values quantized to a second quantity of bits. Numerous other aspects are described.
