Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transmission technologies have limited bandwidth and space-time stream quantities, resulting in a relatively low data transmission rate.
Innovation Solution
The method involves generating data packets with signaling fields that indicate bandwidths greater than 160 MHz and/or space-time stream quantities exceeding 8, allowing for higher bandwidth and larger stream quantities to enhance data transmission rates.

Engineering Contradiction Analysis
1Productivity
If the bandwidth and space-time stream quantity indicated by the signaling field are kept small, then the signaling field structure remains simple and compatible with existing systems, but the data transmission rate remains relatively low
Solution Approach 1:
The signaling field is segmented into multiple independent parts: bandwidth indication information, space-time stream indication information, and resource allocation information. Each segment can be independently configured and interpreted, allowing the system to indicate larger bandwidths and stream quantities without requiring a complete restructuring of the signaling field. This segmentation enables incremental expansion of capabilities while maintaining compatibility with existing parsers.
Solution Approach 2:
The patent introduces a new dimension for indicating bandwidth and stream quantities by using multi-bit field combinations and hierarchical indication mechanisms. Instead of relying on single fixed-size fields, the solution uses multiple bits that can be combined to represent values beyond the traditional 160 MHz and 8 stream limits, effectively expanding the indication capacity without linearly increasing signaling complexity.
2Productivity
If the bandwidth is increased beyond 160 MHz and space-time stream quantity beyond 8, then the data transmission rate increases significantly, but the indication capability of existing signaling fields becomes insufficient
Solution Approach 1:
The patent changes the parameters of the signaling field by expanding the bit width of bandwidth and space-time stream indication fields. Specifically, it uses additional bits to represent bandwidth values greater than 160 MHz and space-time stream quantities greater than 8. This parameter expansion allows the signaling field to convey larger values without losing information about the actual transmission resource allocation.
Solution Approach 2:
The signaling field structure is designed to be universal and multi-functional, capable of indicating both traditional bandwidth values (up to 160 MHz) and extended values (greater than 160 MHz), as well as traditional stream quantities (up to 8) and extended quantities (greater than 8). This universality is achieved through flexible field definitions that can adapt to different transmission scenarios while maintaining a single unified structure.

AI summary
A data transmission method includes: generating a first data packet, where a signaling field in the first data packet includes bandwidth information and space-time stream information, the bandwidth information is used to indicate first bandwidth, and the space-time stream information is used to indicate k first space-time stream quantities corresponding to k receive ends, where k≥1; and sending the first data packet to the k receive ends, where a maximum value of the first bandwidth is greater than 160 MHz, and/or the k first space-time stream quantities meet a preset condition, where the preset condition includes: when k=1, a maximum value of the first space-time stream quantity indicated by the space-time stream information is greater than 8, and when k>1, a maximum value of a sum of the k first space-time stream quantities is greater than 8.
