Broadcast TRS Configuration via SIB for Connected Mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies due to redundant transmission of Tracking Reference Signal (TRS) configurations to User Equipment (UE) via System Information Block (SIB) and dedicated RRC signaling in connected mode, leading to increased signaling overhead, delay, and power consumption.
Innovation Solution
Implementing a method where a UE receives a TRS configuration via SIB in connected mode and performs TRS measurements, while allowing dynamic reconfiguration of TRS resources based on network or device changes, thereby reducing redundant signaling and improving resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If TRS configuration is transmitted via both SIB and dedicated RRC signaling in connected mode, then TRS measurement accuracy is maintained, but signaling overhead and power consumption increase
Solution Approach 1:
The patent extracts the TRS configuration transmission from dedicated RRC signaling and retains only the SIB transmission path. The network device determines whether to transmit TRS configuration information in SIB based on whether the UE is in connected mode, eliminating redundant dedicated signaling while maintaining measurement accuracy through SIB-based configuration.
Solution Approach 2:
The SIB is made universal by enabling it to carry TRS configuration information for both idle and connected mode UEs. The network device dynamically adapts the SIB transmission to serve multiple UE states, replacing the need for separate dedicated signaling paths for different UE modes.
2Measurement precision
If TRS configuration is transmitted via both SIB and dedicated RRC signaling in connected mode, then TRS measurement accuracy is maintained, but signaling overhead increases
Solution Approach 1:
The patent removes the redundant dedicated RRC signaling path for TRS configuration transmission in connected mode, extracting only the essential SIB transmission path. This elimination of redundant information channels reduces signaling overhead while preserving the necessary TRS measurement capability through SIB-based configuration.
3Measurement precision
If TRS configuration is transmitted via both SIB and dedicated RRC signaling in connected mode, then TRS measurement accuracy is maintained, but system complexity increases
Solution Approach 1:
The patent extracts and removes the redundant dedicated RRC signaling mechanism for TRS configuration, simplifying the system architecture to rely primarily on SIB transmission. This reduction in signaling paths decreases system complexity while maintaining measurement functionality.
Solution Approach 2:
The SIB is enhanced to universally serve both idle and connected mode UEs for TRS configuration, consolidating the signaling function into a single versatile mechanism rather than maintaining separate specialized paths for different UE states.
4Ease of manufacture
If TRS resources are statically configured, then configuration simplicity is maintained, but resource utilization efficiency decreases
Solution Approach 1:
The patent implements dynamic TRS resource configuration where the network device can adaptively adjust TRS resource allocation based on UE state and network conditions. The system transitions from static pre-configuration to dynamic determination, allowing TRS resources to be optimized in real-time while maintaining configuration simplicity through automated network control.

AI summary
Apparatuses and methods for broadcast TRS configurations are described. An apparatus is configured to receive, from a network node, a first TRS configuration via a SIB. The apparatus is also configured to monitor, in a connected mode, a first resource for a TRS based on the first TRS configuration. The apparatus is also configured to perform a first set of TRS measurements for the TRS. Another apparatus is configured to provide, for a UE, a first TRS configuration, associated with a TRS for a connected mode of the UE, via a SIB. The apparatus is also configured to communicate, with the UE, based a first set of TRS measurements for the TRS that is associated with a monitored first resource of the TRS associated with the first TRS configuration.
