TRP Synchronization Sequence Grouping for Power Level Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional synchronization sequences in wireless networks do not effectively convey the characteristics of different transmit receive points (TRPs), such as high power or low power, which can lead to inefficient power control and interference management in hypercells with configurable coverage areas.
Innovation Solution
Assigning distinct synchronization sequences to groups of TRPs based on their common characteristics, allowing user equipment (UE) to determine the power level of TRPs and adjust power control accordingly, without additional signaling beyond the synchronization sequences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional synchronization sequences are used for all TRPs, then the system maintains simplicity in sequence assignment, but the ability to convey TRP characteristics (high power/low power) is lost, leading to inefficient power control and interference management
Solution Approach 1:
The patent segments the set of synchronization sequences into multiple groups, where each group is assigned to TRPs with a specific characteristic (e.g., high power or low power). This segmentation allows the system to convey TRP characteristics through sequence group selection without requiring complex additional signaling, thereby resolving the contradiction between information loss and system complexity.
2Reliability
If distinct synchronization sequences are assigned to different TRP groups, then power control and interference management are improved, but the complexity of sequence assignment and management increases
Solution Approach 1:
The patent applies local quality by assigning specific synchronization sequence groups to TRPs based on their local characteristics (high power or low power). Each TRP group uses sequences with properties optimized for its specific power level, improving power control efficiency and interference management while maintaining a manageable level of complexity through structured group assignment.
3Measurement precision
If additional signaling is used to convey TRP characteristics, then the accuracy of power control is improved, but the latency in system access increases
Solution Approach 1:
The patent enables the synchronization sequence itself to carry the TRP characteristic information, allowing the sequence to serve dual purposes: both synchronization and characteristic indication. This self-service approach eliminates the need for separate additional signaling, thereby maintaining high detection accuracy while reducing system access latency.

AI summary
Systems and methods are provided that allow a transmit receive point (TRP) that is a member of a group of TRPs to convey a characteristic of the group through the transmission of a synchronization sequence. A transmit receive point in a first group of TRPs transmits with a first synchronization sequence. A TRP in a second group of TRPs transmits with a second synchronization sequence, the first and second synchronization sequences being different from each other. The TRPs of the first group share a common first characteristic and the TRPs of the second group share a common second characteristic. The transmission of the first synchronization sequence conveys the first common characteristic, and the transmission of the second synchronization sequence conveys the second common characteristic.
