RSS Configuration Indication for Wireless Signaling Overhead Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, especially for machine type communications, the overhead of signaling for idle terminals to obtain reference signal received power (RSRP) or reference signal received quality (RSRQ) from neighboring cells is high due to the need to transmit complete re-synchronization signal (RSS) configuration information for each cell, including frequency domain position, time domain offset, and number of cell-specific reference signal (CRS) ports.
Innovation Solution
An information indication method where a base station sends a configuration indication to terminals, allowing them to determine if neighboring cell RSS configuration information is the same as the serving cell's, thereby reducing the need to transmit all configuration information and using cell identifiers to acquire differing configurations, thus minimizing signaling overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If complete RSS configuration information is indicated for each neighboring cell, then measurement precision of RSRP/RSRQ is improved, but signaling overhead becomes excessively large
Solution Approach 1:
The patent segments the RSS configuration information into two parts: common configuration information (shared across multiple cells) and cell-specific configuration information (unique to each cell). This segmentation allows the system to transmit only the cell-specific parts when needed, reducing overall signaling overhead while maintaining measurement precision for cells that differ from the serving cell.
Solution Approach 2:
The patent merges the configuration information of multiple neighboring cells by identifying and transmitting common configuration information once that applies to multiple cells. This combining approach reduces redundancy and minimizes the total amount of signaling required while ensuring all necessary measurement parameters are available.
2Adaptability or versatility
If RSS configuration information of all neighboring cells is transmitted, then adaptability of measurement is improved, but device complexity increases
Solution Approach 1:
The patent applies partial action by transmitting only the necessary cell-specific RSS configuration information rather than all possible configuration information for all cells. The terminal selectively acquires and processes only the configuration data needed for cells that differ from the serving cell, reducing processing complexity while maintaining adaptability for measurements where differences exist.
3Measurement precision
If detailed RSS configuration information is indicated for each cell, then measurement accuracy is improved, but loss of time increases
Solution Approach 1:
The patent implements preliminary action by pre-identifying which neighboring cells have the same RSS configuration as the serving cell and which have different configurations. This preliminary classification allows the terminal to skip acquiring configuration information for cells that are identical to the serving cell, reducing time consumption while maintaining accuracy for cells that require differentiated measurement parameters.
