Solution Overview

Problem

In wireless communication systems, the Medium Access Control (MAC) layer faces inefficiencies in data transmission due to varying data rates and service qualities across channels, leading to inefficient utilization of wireless resources and excessive use of control information for mapping data blocks, which can clog transmission channels.

Innovation Solution

A method is introduced where a MAC layer data block is configured with a header containing specific fields for mapping information, allowing efficient mapping of higher layer data blocks to lower layer channels, minimizing the use of transport channel resources while ensuring accurate separation of data blocks at the receiving end.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If detailed mapping information is provided for each data block, then the receiving end can accurately identify and separate data blocks, but the control information volume increases and clogs transmission channels

Engineering Contradiction:
Improvedata block identification accuracyVSAvoidcontrol information volume
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The patent combines multiple data blocks from different logical channels into a single MAC layer data block for transmission over one transport channel. By merging data blocks that share the same transport channel mapping, the system eliminates the need for separate mapping information for each block, thereby reducing control information volume while maintaining identification accuracy through the unified structure.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The invention creates a universal MAC layer data block structure that can accommodate multiple higher layer data blocks from different logical channels. This multi-functional structure serves both as a container for diverse data sources and as a unified transmission unit, eliminating the need for channel-specific mapping information and reducing overall control overhead.

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

2Productivity

If multiple data channels are mapped to a single transport channel, then wireless resource utilization improves, but the complexity of data block management and separation increases

Engineering Contradiction:
Improvewireless resource utilizationVSAvoiddata block management complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the MAC layer data block into distinct regions or fields that correspond to different logical channels. Each segment contains metadata or identifiers that enable the receiving end to easily separate and route data blocks to the appropriate logical channel, thereby managing complexity through structured segmentation while maintaining efficient resource utilization.

Inventive Principle:
Principle #1Segmentation

3Reliability

If separate transport channels are used for each data channel, then data transmission accuracy is maintained, but wireless resource waste increases

Engineering Contradiction:
Improvedata transmission accuracyVSAvoidwireless resource waste
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent merges multiple logical channels into a single transport channel by creating a unified MAC layer data block structure. This combination maintains transmission accuracy through the preserved logical channel identifiers within the merged block while eliminating the waste of dedicated transport channel resources, thereby achieving both reliability and resource efficiency.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A method of processing data in a Medium Access Control (MAC) layer through which at least one first channel is mapped to a second channel in a transmitting end of a wireless communication system is disclosed. More specifically, a MAC layer data block is configured by including at least one higher layer data block received through the at least one first channel and adding a header thereto which includes at least one field which indicates at least two types of information. Furthermore, the MAC layer data block is tranferred to a lower layer through the second channel.
