UE Non-Cellular Receiver Status Reporting for Reliable Measurements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication networks face issues with UEs not performing and reporting non-cellular measurements as requested, leading to problems and difficulties for the cellular network.
Innovation Solution
UEs and network nodes are configured to report the status of their non-cellular receivers and coverage during measurement durations, including enabling specific non-cellular signal measurements and reporting indications of receiver enablement and coverage status.

Engineering Contradiction Analysis
1Reliability
If UEs are configured to perform non-cellular measurements, then measurement information becomes available for network optimization, but UEs may not reliably perform or report these measurements due to receiver status issues
Solution Approach 1:
The patent implements a feedback mechanism where UEs report not only measurement results but also the operational status of their non-cellular receivers. This feedback allows the network to understand why measurements may be missing or incomplete, enabling better decision-making about network optimization actions and UE configuration adjustments.
Solution Approach 2:
The patent requires UEs to report receiver status information in advance or alongside measurement data. This preliminary information about receiver enablement state allows the network to proactively identify potential measurement issues before they affect network optimization decisions, rather than reacting to missing data afterward.
2Reliability
If UEs report detailed measurement status information, then network can take appropriate remedial actions, but reporting complexity and signaling overhead increase
Solution Approach 1:
The patent segments the measurement reporting into distinct components: receiver status information (enabled/disabled state) and measurement results. This segmentation allows the network to process different types of information separately and take appropriate actions based on the combination of status and measurement data, reducing overall system complexity.
Solution Approach 2:
The patent introduces a new parameter (receiver status indication) to the existing measurement reporting framework. By adding this binary parameter rather than creating a completely new complex reporting mechanism, the patent maintains compatibility with existing systems while enabling more sophisticated network optimization decisions.

AI summary
Embodiments include methods for a user equipment (UE) configured to operate in a cellular radio access network (RAN). Such methods include receiving, from the cellular RAN, a measurement reporting configuration comprising identification of non-cellular signals, of one or more types, for which measurements are requested from the UE. Such methods include measuring at least the identified non-cellular signals and transmitting, to the cellular RAN, a measurement report including one or more of the following for each particular type of identified non-cellular signal: a first indication of whether the UE's corresponding non-cellular receiver was enabled during a measurement duration, and a second indication of whether the UE was out-of-coverage during the measurement duration in relation to all identified non-cellular signals of the particular type. Other embodiments include complementary methods for a network node, as well as UEs and network nodes configured to perform such methods.
