Reference Signal Resource Configuration for UE Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile communication systems face challenges in reducing power consumption of user equipment (UE) when performing operations using reference signal resources, leading to increased power consumption and reduced processing performance due to discontinuous sending of these signals.
Innovation Solution
A communication method where a network device sends configuration information and bit fields to a terminal device, indicating the availability and usage status of reference signal resources, allowing the terminal device to selectively use existing or newly configured resources for operations like RRM measurement, thereby avoiding unnecessary power consumption and improving accuracy and performance.

Engineering Contradiction Analysis
1Use of energy by moving object
If the network device discontinuously sends reference signal resources, then power consumption of the terminal device is reduced, but operation accuracy deteriorates due to unnecessary operations
Solution Approach 1:
The network device sends indication information in advance to notify the terminal device about the availability status of reference signal resources before the terminal device performs operations. This allows the terminal device to prepare appropriately and avoid unnecessary operations, thereby reducing power consumption while maintaining operation accuracy.
Solution Approach 2:
The network device provides feedback to the terminal device through indication information, telling the terminal device whether reference signal resources are available. This feedback mechanism enables the terminal device to adjust its operations based on actual resource availability, avoiding unnecessary operations and reducing power consumption while ensuring accurate operations when resources are available.
2Productivity
If the terminal device performs operations using reference signal resources, then processing performance is improved, but power consumption increases
Solution Approach 1:
The terminal device performs operations partially or selectively based on the indication information received from the network device. When reference signal resources are available, the terminal device performs necessary operations to maintain processing performance. When resources are unavailable, the terminal device avoids unnecessary operations, thereby reducing power consumption while maintaining adequate processing performance through selective action.
3Measurement precision
If the network device sends indication information about reference signal resource availability, then operation accuracy is improved, but device complexity increases
Solution Approach 1:
The indication information about reference signal resource availability is extracted and sent separately from the main communication protocol. This separate indication mechanism provides accurate operation guidance to the terminal device without significantly complicating the overall communication protocol structure, thereby improving operation accuracy while minimizing the increase in device complexity.

AI summary
The technology of this application relates to communications systems. In one example, a network device sends a first message to a terminal device, where the first message includes configuration information of a reference signal resource. The network device sends a second message to the terminal device, where the second message includes a first bit field and/or a second bit field, the first bit field is used to indicate an availability status of the reference signal resource, and the second bit field is used to indicate that the terminal device uses a synchronization signal/physical broadcast channel resource block signal resource and/or the reference signal resource.
