Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently managing beam connections between resources, particularly in predicting channel state information (CSI) for improved spectral efficiency and mobility in 5G and New Radio (NR) networks.
Innovation Solution
A mobile station and network node exchange indications of resource sets and connections between these sets, enabling the mobile station to measure and predict CSI values, while a network node receives CSI reports to optimize beam management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If beam management uses traditional measurement methods for all resources, then measurement accuracy is maintained, but signaling overhead and processing complexity increase
Solution Approach 1:
The patent segments beam management resources into two distinct sets: a first set of resources for actual CSI measurements and a second set of resources for predicted CSI values. This segmentation allows the system to avoid measuring all beam resources directly, thereby reducing signaling overhead and processing complexity while maintaining measurement accuracy for the most critical beams through selective measurement of the first resource set.
Solution Approach 2:
The patent implements preliminary action by establishing connections between resources in advance. The network node configures the mobile station with indication information that defines relationships between first set resources (to be measured) and second set resources (to be predicted). This pre-established connection framework enables the mobile station to predict CSI for the second resource set based on measurements from the first resource set, reducing the need for extensive direct measurements.
2Loss of energy
If the system reduces the number of measured resources, then signaling overhead decreases, but CSI prediction accuracy may deteriorate
Solution Approach 1:
The patent incorporates feedback mechanisms where the mobile station reports CSI measurements for the first resource set to the network node. The network node uses this feedback information, combined with the pre-established connection relationships, to generate accurate CSI predictions for the second resource set. This feedback loop ensures that even with reduced direct measurements, the predicted CSI maintains high accuracy through iterative refinement based on actual measurement feedback.
Solution Approach 2:
The patent changes the parameter of resource measurement by introducing connection relationship indicators that define how first set resources relate to second set resources. By modifying the resource indication parameters to include these predictive relationships, the system can derive accurate CSI for unmeasured resources through mathematical transformations and predictions based on the connection definitions, thereby maintaining precision with fewer direct measurements.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a mobile station may receive, from a network node, an indication of a first set of resources and a second set of resources and an indication of one or more connections between the first set of resources and the second set of resources. The mobile station may transmit, to the network node, a channel state information report indicating measurement values associated with the first set of resources and the second set of resources, wherein a first one or more measurement values, from the measurement values, associated with the first set of resources are measured by the mobile station, and wherein a second one or more measurement values, from the measurement values, associated with the second set of resources are predicted by the mobile station. Numerous other aspects are described.
