Service-Associated Reference Signals for Wireless Device Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, devices often inefficiently process and transmit measurement reports to determine service types supported by other devices, leading to unnecessary resource usage and potential handover inefficiencies due to the lack of initial service type information in reference signals.
Innovation Solution
Transmitting reference signals that indicate the service type supported by the transmitting device, allowing receiving devices to determine if they support the same service type before measuring signal strength and transmitting reports, thereby optimizing resource usage and handover processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the receiving device measures reference signals and transmits measurement reports without prior service type information, then the device can establish connections with potential transmitting devices, but unnecessary processing and transmission occur when service types are incompatible
Solution Approach 1:
The patent applies preliminary action by incorporating service type information directly into the reference signal transmission. The receiving device extracts service type information from the reference signal before performing measurement operations, allowing it to pre-determine compatibility and avoid unnecessary measurement and reporting processes for incompatible devices, thus reducing power consumption while maintaining connection establishment efficiency
2Reliability
If the receiving device processes all reference signals regardless of service type compatibility, then no measurement reports are missed, but system resources are wasted on incompatible device pairs
Solution Approach 1:
The patent enables preliminary filtering by embedding service type information in the reference signal. The receiving device performs preliminary compatibility checking by comparing service types extracted from the reference signal with its own supported service types before proceeding with measurement and reporting, ensuring no compatible measurements are missed while eliminating resource waste on incompatible device pairs
3Productivity
If the reference signal includes service type information, then the receiving device can filter incompatible transmissions early, but the reference signal structure becomes more complex
Solution Approach 1:
The patent applies universality by designing the reference signal to serve multiple functions simultaneously: it maintains its traditional role for channel estimation and measurement while additionally carrying service type information through existing signal structures such as scrambling sequences, resource element patterns, or signal parameters. This multi-functionality approach enhances resource usage efficiency without significantly increasing reference signal structure complexity

AI summary
Methods, systems, and devices for wireless communications are described. In some systems, a transmitting device may transmit a reference signal indicating a first service type supported by the transmitting device and a receiving device may receive the reference and determine whether to measure a signal strength associated with the reference signal based on determining whether the first service type supported by the transmitting device and a second service type supported by the receiving device are a same service type. For example, the receiving device may measure the reference signal if the first service type indicated by the reference signal and the second service type supported by the receiving device are the same service type. Alternatively, the receiving device may refrain from measuring the reference signal if the first service type indicated by the reference signal and the second service type supported by the receiving device are different service types.
