Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless LAN standards face challenges in providing high-speed services for new multimedia applications, particularly in managing resource allocation and signaling discontinuous channels to terminals.
Innovation Solution
A method and device for transmitting information on discontinuous channel allocation in a wireless communication system, utilizing a physical protocol data unit (PPDU) with a universal signal (U-SIG) and extremely high throughput (EHT)-SIG field to efficiently signal and allocate resources to multiple terminals, including low density parity check code (LDPC) and space-time block coding (STBC) fields, with repeated transmission and puncturing patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If discontinuous channel allocation is implemented to improve resource utilization, then resource use rate increases, but signaling complexity increases
Solution Approach 1:
The bandwidth is divided into multiple segments, and the resource allocation information is segmented accordingly. Each segment contains resource allocation fields that can be independently decoded, allowing terminals to efficiently process discontinuous channel allocations without overwhelming signaling complexity
Solution Approach 2:
The patent introduces a new dimension to resource allocation by implementing discontinuous channel allocation across multiple segments. This allows resources to be allocated in a multi-dimensional space (across segments) rather than continuously in a single dimension, improving resource utilization while maintaining manageable signaling through structured segmentation
2Productivity
If resource allocation information is transmitted to multiple terminals, then resource allocation efficiency improves, but signaling overhead increases
Solution Approach 1:
The resource allocation fields are designed to be universal and applicable to multiple terminals simultaneously. The same segmented structure and resource allocation fields serve multiple terminals, reducing redundant signaling while maintaining efficient resource allocation across the network
Solution Approach 2:
The patent uses repeated transmission of segmented resource allocation information across different segments. Terminals can decode resource allocation from any segment, effectively creating redundant copies that reduce signaling overhead while ensuring reliable delivery to multiple terminals

AI summary
Disclosed is a method for receiving data by a terminal in a wireless communication system. The terminal may receive a physical protocol data unit (physical layer protocol data unit: PPDU) from an access point (APAP) and decode the received PPDU. The PPDU may include a universal signal (U-SIG) field and an extremely high throughput (EHT)-SIG field including at least one content channel, and the U-SIG field may include a bandwidth field indicating the total bandwidth via which the PPDU is transmitted. The total bandwidth is divided into at least one segment, and at least one of field among same fields includes same information except for a resource unit allocation (RU allocation) field between a first content channel and a second content channel in the same segment among the at least one segment when the at least one content channel is composed of a first content channel and a second content channel.
