Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If larger bandwidths are used for communication at high frequencies, then communication capacity is improved, but symbol time interval decreases and control signaling becomes more complex

Engineering Contradiction:
Improvecommunication capacityVSAvoidcontrol signaling complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The transmission timing structure is segmented into multiple signaling blocks, where a subset of M blocks represents control signaling and the remaining N-M blocks represent data signaling. This segmentation allows the system to handle control and data separately, reducing the complexity of control signaling while maintaining large bandwidth capacity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a new dimensional organization of signaling resources by defining a transmission timing structure with N signaling blocks, where control signaling occupies M blocks and data signaling occupies N-M blocks. This dimensional approach separates control and data in the time domain, simplifying control signaling handling while supporting large bandwidths.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

If bandwidth increases to 1 GHz or 2 GHz, then data transmission capability is improved, but cyclic prefix length decreases

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The patent employs dynamic signaling block structures where the transmission timing can be flexibly configured with N signaling blocks, allowing the system to adapt cyclic prefix lengths and symbol durations dynamically based on bandwidth requirements. This enables maintaining adequate cyclic prefix protection even at 1 GHz or 2 GHz bandwidths.

Inventive Principle:

3Productivity

If reference signaling elements are positioned flexibly based on M and control signaling location, then demodulation efficiency is improved, but signaling structure complexity increases

Engineering Contradiction:
Improvedemodulation efficiencyVSAvoidsignaling structure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

Reference signaling elements are positioned locally within the transmission timing structure based on the specific location of control signaling blocks (M blocks). This local positioning ensures that reference signals are optimally placed near their associated control signaling, improving demodulation efficiency without requiring system-wide reconfiguration.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The transmission timing structure is designed to self-organize reference signaling elements based on the configuration of control and data signaling blocks. The structure automatically determines reference signal positions according to the M control blocks and N-M data blocks arrangement, reducing the need for external configuration and minimizing signaling overhead.

Inventive Principle:
Principle #25Self-service

AI summary

There is disclosed a method of operating a transmitting node in a millimeter-wave communication network. The method includes transmitting millimeter-wave signaling in a transmission timing structure, the transmission timing structure including N time interval elements sequentially ordered in time, the millimeter-wave signaling including N separate signaling structures, each signaling structure being transmitted in a different one of the time interval elements. N is an integer multiple of 2. A first subset of the N separate signaling structures corresponds to control signaling, the subset including 2{circumflex over ( )}m signaling structures consecutive in time beginning with the signaling structure of the first time interval element, and m is an integer such that 2{circumflex over ( )}m<=N. A second subset of the N separate signaling structures corresponds to data signaling, the second subset comprising 0 or an integer number of signaling structures. The disclosure also pertains to related devices and methods.
