Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G wireless communication systems, effectively indicating the locations of time-domain resources for transmitting synchronization signal blocks is challenging due to the flexibility in beam coverage and resource allocation, leading to increased signaling overhead.
Innovation Solution
A method where a network device determines and transmits information about the number and specific time-domain locations of synchronization signal blocks to a terminal device, using fewer bits to indicate these locations, thereby reducing signaling overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the locations of time-domain resources for synchronization signal blocks are flexibly changed to cover entire cell with multiple beams, then the coverage capability is improved, but the signaling overhead for indicating these locations increases
Solution Approach 1:
The patent segments the time-domain resource indication into two parts: a first indication part that specifies the set of time-domain resource units, and a second indication part that specifies the actual used units within that set. This segmentation allows flexible beam coverage while reducing signaling overhead by avoiding the need to indicate all possible time-domain locations individually.
Solution Approach 2:
The patent introduces a first indication part that provides preliminary information about the time-domain resource unit set before the actual synchronization signal block transmission. This preliminary indication allows the terminal to prepare for receiving multiple SS blocks on different beams without requiring full detailed indication for each possible location, thus reducing overall signaling overhead.
2Adaptability or versatility
If multiple synchronization signal blocks are transmitted on different beams with flexible time-domain locations, then the beam coverage capability is improved, but the complexity of indicating time-domain resource locations increases
Solution Approach 1:
The indication information is segmented into a first indication part (specifying the time-domain resource unit set) and a second indication part (specifying the actual used units). This segmentation simplifies the complexity by breaking down the full indication task into manageable parts, allowing flexible beam coverage while reducing the complexity of indicating all possible time-domain locations.
Solution Approach 2:
The patent uses partial indication by providing a first indication part that describes a set of time-domain resource units, then uses a second indication part to specify only the actual used units within that set. This partial action approach reduces the complexity of indicating all possible locations while maintaining the flexibility to support multiple beams.
3Measurement precision
If detailed indication of all time-domain resource locations is provided for flexible beam transmission, then the location accuracy is improved, but the signaling overhead increases
Solution Approach 1:
The patent segments the location indication into a first indication part (time-domain resource unit set) and a second indication part (actual used units). This segmentation maintains location accuracy by precisely indicating the actual used units while reducing signaling overhead by avoiding the need to indicate all possible time-domain locations in detail.
Solution Approach 2:
The first indication part provides preliminary information about the time-domain resource unit set, establishing the context before the second indication part specifies the actual used units. This preliminary action maintains location accuracy while reducing overhead by avoiding redundant detailed indication for all possible locations.

AI summary
The present application discloses a method for transmitting a signal, a network device, and a terminal device. The method includes: a network device determines transmission information of a synchronization signal block, where the transmission information includes information on the number m of the synchronization signal block, and information on a time-domain resource set over which the m synchronization signal block is transmitted, where the time-domain resource set includes m time-domain resource unit over which the m synchronization signal block is transmitted, and locations of m time-domain resource units in different time-domain resource sets are not completely the same; the network device sending the transmission information to a terminal device, so that the terminal device receives, according to the transmission information, the m synchronization signal block transmitted by the network device. Thereby, the network device is capable of effectively indicating to the terminal device the locations of time-domain resources for transmitting the synchronization signal block.
