Solution Overview

Problem

In 5G wireless communications and high-speed backhaul systems, beamforming and beamsteering technologies face challenges during beam adjustment, leading to signal quality issues and potential data transmission interruptions due to the unstable status of components like phase shifters or switches, necessitating suspension of data transmission during beam switching, which increases delay and reduces timeliness.

Innovation Solution

A data transmission method that includes generating data frames with identification information indicating the validity of data in switching intervals, allowing the receive device to determine if the transmit device is performing beam adjustment, thereby avoiding the need for separate requests and reducing interaction delays, and includes a protection interval for data migration to ensure continuous and reliable transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If beam switching is performed using conventional methods with separate requests, then beam adjustment can be made, but transmission delay increases and timeliness deteriorates

Engineering Contradiction:
Improvebeam switching reliabilityVSAvoidtransmission delay
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent merges the beam adjustment request with the data transmission frame by incorporating identification information directly into the data frame structure. This eliminates the need for separate request interactions between transmitter and receiver, allowing beam switching to occur without additional delay from separate signaling exchanges.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The identification information indicating beam adjustment status is embedded in advance within the data frame structure before transmission. This allows the receiver to proactively identify when beam adjustment is needed and prepare accordingly, eliminating waiting time for separate requests and responses.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If data transmission is suspended during beam switching, then data integrity is maintained, but transmission efficiency decreases

Engineering Contradiction:
Improvedata integrityVSAvoidtransmission efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent dynamically adjusts the status of switching intervals based on beam adjustment requirements. The identification information enables the system to selectively mark intervals as valid or invalid during beam switching, allowing continuous transmission while ensuring data integrity through dynamic status management rather than complete suspension.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The data transmission is segmented into switching intervals with identification information indicating validity. This allows the system to process beam switching in specific intervals while maintaining transmission in other intervals, preventing complete suspension and improving overall transmission efficiency while preserving data integrity.

Inventive Principle:
Principle #1Segmentation

3Reliability

If identification information is added to data frames, then beam adjustment status can be tracked, but device complexity increases

Engineering Contradiction:
Improvebeam adjustment trackingVSAvoiddata frame structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The identification information in the data frame serves multiple functions: it indicates beam adjustment status, enables the receiver to proactively manage switching intervals, and maintains data integrity. This multi-functionality reduces the need for separate signaling mechanisms, offsetting the structural complexity with functional consolidation.

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

4Productivity

If switching intervals are allocated on-demand with requests, then transmission efficiency improves, but interaction delay increases

Engineering Contradiction:
Improvetransmission efficiencyVSAvoidinteraction delay
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent converts the potential harm of additional data frame elements into a benefit by using the identification information to enable proactive beam adjustment management. The receiver can identify and respond to beam switching needs immediately upon receiving the frame, eliminating the need for separate request interactions and reducing overall interaction delay.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

AI summary

A data transmission method and an apparatus are disclosed. The method includes: generating, by a first transmit device, a data frame sequence, where the first data frame sequence includes a first data frame, the first data frame includes a switching interval, the switching interval includes first identification information, and the first data frame corresponds to a first data period; detecting, by the first transmit device, whether a beam adjustment request is received within the first data period, and if the beam adjustment request is received, setting the first identification information in the switching interval of the first data frame to invalid; or if no beam adjustment request is received, setting the first identification information to valid; and sending, by the first transmit device, the first data frame.
