Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Millimeter wave (mmW) wireless communication systems face challenges in efficiently transmitting data and control information due to increased signal attenuation and limitations in beamforming techniques, which restrict the ability to communicate effectively between wireless nodes without switching transmission beams or consuming additional synchronization blocks.
Innovation Solution
The method involves configuring a synchronization slot with multiple synchronization blocks, assigning data or control regions to specific frequency portions, and transmitting synchronization signals and data/control information using the same transmission beam, allowing for efficient utilization of bandwidth and reduced power consumption by utilizing unused portions of OFDM symbols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beamforming techniques are used to overcome signal attenuation in mmW communication, then signal transmission reliability is improved, but device complexity increases due to the need for multiple beams and beam switching
Solution Approach 1:
The patent combines synchronization signals and data/control information into a single synchronization block transmitted through one beam. This merging approach eliminates the need for separate beams for synchronization and data transmission, thereby reducing device complexity while maintaining signal transmission reliability through the unified structure.
Solution Approach 2:
The synchronization block serves multiple functions simultaneously: it contains synchronization signals for timing and frequency alignment, and also carries data or control information. This multi-functionality allows a single beam to handle both synchronization and data transmission tasks, reducing the need for multiple specialized beams and thereby decreasing device complexity.
2Reliability
If additional synchronization blocks are used to transmit data and control information, then transmission reliability is improved, but loss of time increases due to extended synchronization burst duration
Solution Approach 1:
The patent merges data and control information into the same synchronization block that carries synchronization signals. This combination allows all information to be transmitted within a single synchronization block rather than requiring multiple separate blocks, thereby reducing the overall synchronization burst duration while maintaining transmission reliability.
Solution Approach 2:
The patent utilizes frequency division by allocating different frequency portions within the same synchronization block for different types of information (synchronization signals, data, control information). This dimensional approach allows multiple information streams to coexist in the same time and beam resource, reducing time loss while maintaining reliability through diversified information carrying capacity.
3Adaptability or versatility
If beam switching is performed to transmit data and control information, then transmission versatility is improved, but loss of time increases due to beam switching overhead
Solution Approach 1:
The patent combines multiple information types (synchronization signals, data, control information) into a single synchronization block transmitted through one beam. This eliminates the need for beam switching between different information types, thereby reducing time loss while maintaining transmission versatility through the unified multi-functional block structure.
Solution Approach 2:
The patent employs frequency division within the synchronization block to accommodate different information types. By utilizing the frequency dimension rather than switching beams in the spatial dimension, the system maintains transmission versatility for different information types while avoiding the time loss associated with beam switching operations.
