Synchronization Resource Selection for Parameter Conveyance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly in LTE technology, face inefficiencies in conveying parameter information from base stations to user equipment, especially in systems that perform beam sweeping in multiple directions, leading to increased latency and reduced utilization of available OFDM symbols.
Innovation Solution
A method where a base station selects specific resources for transmitting synchronization signals based on parameter information, using techniques such as guard subcarrier lengths, center frequency distances, and transmission orders to convey parameters like duplex configuration and cyclic prefix duration, allowing the user equipment to determine these parameters by detecting the resources used for signal transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beam sweeping in multiple directions is performed to improve coverage, then system reliability is improved, but latency increases and OFDM symbol utilization decreases
Solution Approach 1:
The patent combines multiple functions into the synchronization signal resource selection mechanism. The same resource selection that determines synchronization signal transmission also conveys multiple parameter information (duplex configuration, cyclic prefix duration, etc.), thereby improving resource utilization and reducing latency while maintaining coverage through beam sweeping
Solution Approach 2:
The synchronization signal resources serve multiple purposes: they provide synchronization, convey parameter information, and indicate beam directions. This multi-functionality allows the system to maintain reliable multi-directional coverage while efficiently utilizing OFDM symbols and reducing overall latency
2Adaptability or versatility
If traditional parameter indication methods are used, then system compatibility is maintained, but resource utilization of OFDM symbols is reduced
Solution Approach 1:
The patent merges parameter indication with synchronization signal transmission by selecting specific OFDM symbols and resource elements for synchronization signals based on parameter values. This combination eliminates dedicated parameter indication overhead and improves OFDM symbol utilization while maintaining backward compatibility through standardized resource selection patterns

AI summary
According to an aspect of the disclosure, a base station may convey the parameter information to the UE based on selection of particular resources to be used for transmission of synchronization signals, where the selected resources correspond to the particular parameter information. The UE may blindly detect the synchronization signals on various candidate resources and determine the parameter information based on the resources where the synchronization signals are detected. The apparatus may be a base station. In an aspect, the base station determines parameter information of one or more parameters. The base station selects, based on the parameter information, synchronization resources from a plurality of candidate resources for transmission of one or more synchronization signals, where the selected synchronization resources correspond to the parameter information. The base station transmits the one or more synchronization signals using the selected synchronization resources.
