Preamble Puncturing Indication for Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies face challenges in efficiently indicating multiple resource units for data transmission, particularly in scenarios with preamble puncturing, leading to high signaling overheads.
Innovation Solution
A data transmission method and device that utilize preamble puncturing indication information to determine the status of preamble puncturing, allowing for reduced signaling overheads by indirectly indicating allocated resource units based on the puncturing information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple resource units are directly indicated for data transmission, then resource allocation accuracy is improved, but signaling overhead increases
Solution Approach 1:
The patent introduces an intermediary mapping relationship between resource unit indicators and actual resource units. Instead of directly indicating multiple resource units, the system uses a first indicator to point to a mapping relationship, which then maps to multiple second indicators, each corresponding to a specific resource unit. This intermediary mapping mechanism reduces signaling overhead while maintaining the ability to accurately indicate multiple resource units.
Solution Approach 2:
The patent segments the indication process into multiple stages: a first indicator indicating a mapping relationship, and multiple second indicators derived from that mapping relationship, each corresponding to a specific resource unit. This segmentation allows the system to efficiently indicate multiple resource units without transmitting excessive signaling information, as the mapping relationship can be reused across multiple indications.
2Adaptability or versatility
If preamble puncturing is used to allocate discrete resources, then resource allocation flexibility is improved, but indication complexity increases
Solution Approach 1:
The patent creates a universal mapping relationship that can serve multiple functions: it can indicate multiple resource units simultaneously, support preamble puncturing scenarios, and work with both OFDMA and non-OFDMA transmission modes. The mapping relationship acts as a multi-functional tool that handles various resource allocation scenarios without requiring separate indication mechanisms for each case, thereby reducing indication complexity while maintaining flexibility.
Data Source
AI summary
This application discloses a data transmission method and device, a chip system, and a computer-readable storage medium. In the method, a station may receive preamble puncturing indication information, where the preamble puncturing indication information includes one or more indicators, and one indicator corresponds to preamble puncturing information of a data packet; and send or receive the data packet based on the preamble puncturing indication information. The preamble puncturing information includes a size and location of preamble puncturing, or there is no preamble puncturing. The preamble puncturing information may be an index indicated by the preamble puncturing indication information, to learn of a status of preamble puncturing in the data packet.
