Solution Overview

Problem

Existing wireless communication systems using MIMO technology face increased overhead and packet corruption due to repeated encoding of bandwidth and stream allocation information, which is inefficient and prone to interference, especially in environments with multiple users.

Innovation Solution

Jointly encode bandwidth and stream allocation information in a common portion of a physical layer header, reducing redundant encoding and minimizing overhead while enhancing reliability through separate encoding and CRC masking.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If bandwidth and stream allocation information is encoded separately for each wireless device, then each device can receive its specific allocation information, but the overhead increases and the bandwidth consumption increases

Engineering Contradiction:
Improvedelivery reliabilityVSAvoidbandwidth consumption
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent combines bandwidth allocation information and stream allocation information into a single joint encoding process. Instead of encoding these parameters separately for each wireless device, the base station encodes them together in a unified manner, reducing the total number of encoded packets and minimizing bandwidth overhead while ensuring reliable delivery to multiple devices.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If bandwidth and stream allocation information is encoded multiple times for multiple wireless devices, then each device receives its information, but the packet error rate increases due to more transmission opportunities for corruption

Engineering Contradiction:
Improveinformation delivery reliabilityVSAvoidpacket error rate
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The patent merges the encoding of bandwidth and stream allocation information into a single joint encoding operation that serves multiple wireless devices simultaneously. This reduces the number of separate transmission instances, thereby minimizing the cumulative probability of packet corruption while ensuring all devices receive their required allocation information reliably.

Inventive Principle:
Principle #5Merging (Combining)

3Productivity

If bandwidth and stream allocation information is encoded in a common portion of the physical layer header, then overhead is reduced and bandwidth efficiency improves, but the complexity of the encoding process increases

Engineering Contradiction:
Improvedata transmission efficiencyVSAvoidencoding complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the physical layer header into a common portion and device-specific portions. The common portion contains jointly encoded bandwidth and stream allocation information that applies to multiple devices, while device-specific portions contain individualized information. This segmentation allows efficient reuse of common information across multiple devices while maintaining the ability to address individual device requirements.

Inventive Principle:
Principle #1Segmentation

4Quantity of substance

If bandwidth and stream allocation data are encoded once in a physical layer frame header, then the overhead is minimized, but ensuring accurate delivery to all wireless devices becomes more challenging

Engineering Contradiction:
Improveoverhead bandwidthVSAvoiddelivery reliability
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The patent creates a universal encoding structure in the common portion of the physical layer header that serves multiple wireless devices simultaneously. The jointly encoded bandwidth and stream allocation information is designed to be universally applicable to all devices in the group, reducing overhead while maintaining reliability through the unified encoding approach that minimizes transmission instances.

Inventive Principle:
Principle #6Universality (Multi-functionality)
