Solution Overview
Problem
In 5G New Radio (NR) systems, there is a need to enhance communication performance regarding the transmission of synchronization signal blocks, which current technologies have not adequately addressed.
Innovation Solution
A wireless communication method where a network device indicates resource positions and/or quantities of synchronization signal blocks to a terminal device, allowing the terminal to receive these signals efficiently, thereby reducing unnecessary detection and improving communication performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal device detects all possible synchronization signal blocks, then the coverage is complete, but the detection delay and power consumption increase
Solution Approach 1:
The network device performs preliminary action by indicating to the terminal device which synchronization signal blocks will be transmitted before the terminal device performs detection. This allows the terminal device to prepare and focus its detection efforts only on the indicated blocks, avoiding unnecessary detection of other blocks, thereby reducing detection delay while ensuring complete coverage of all transmitted blocks.
2Reliability
If the terminal device detects all possible synchronization signal blocks, then the coverage is complete, but the power consumption increases
Solution Approach 1:
The network device provides advance information about which synchronization signal blocks will be transmitted, enabling the terminal device to concentrate its power consumption only on detecting the indicated blocks rather than scanning all possible blocks. This significantly reduces the terminal device's power consumption while maintaining complete detection coverage of all transmitted blocks.
3Device complexity
If the network device transmits synchronization signal blocks without indication information, then the transmission is simple, but the terminal device cannot efficiently locate the blocks
Solution Approach 1:
The patent introduces indication information as an intermediary between the network device's transmission and the terminal device's detection. This indication information acts as a guide that efficiently directs the terminal device to the locations of transmitted synchronization signal blocks, solving the problem of inefficient location without significantly increasing overall system complexity, as the indication can be integrated into existing signaling mechanisms.
