Resource Unit Scheduling for High-Frequency Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-frequency wireless communication systems face low data transmission efficiency due to the use of high subcarrier spacings that result in short slots, making traditional slot-based scheduling inefficient.
Innovation Solution
Introduce a larger scheduling unit called a resource unit (RU) comprising N subcarriers and M consecutive slots, allowing flexible scheduling of data transmission channels without being limited by slot size, and adapt LBT methods to improve efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high subcarrier spacings are used to resist multipath fading, then resistance to multipath fading is improved, but slot duration becomes short resulting in low data transmission efficiency
Solution Approach 1:
The patent divides the traditional slot-based scheduling unit into smaller resource blocks (RBs) that can be flexibly combined. Each RB contains a specific number of subcarriers and symbols, allowing the system to segment resources according to actual transmission needs rather than being constrained by fixed slot boundaries. This segmentation enables efficient utilization of high SCS configurations while maintaining appropriate transmission durations.
Solution Approach 2:
The patent introduces dynamic resource allocation where the number of resource blocks, their positions in frequency and time domains, and their configurations can be adaptively adjusted based on channel conditions, traffic requirements, and SCS settings. This dynamic approach allows the system to optimize the balance between resistance to multipath fading and data transmission efficiency for each transmission scenario.
2Ease of operation
If traditional slot-based scheduling is used, then scheduling simplicity is maintained, but data transmission efficiency becomes very low due to short slot duration
Solution Approach 1:
The patent extends the scheduling dimension from traditional time-domain slot-based allocation to include flexible resource block groupings that span both time and frequency domains. By introducing resource blocks as the basic scheduling unit with configurable numbers of subcarriers and symbols, the system creates an additional degree of freedom in resource allocation, enabling more efficient scheduling without significantly increasing complexity.
Solution Approach 2:
The patent designs a universal resource block structure that can accommodate different SCS configurations, transmission types (uplink, downlink, sidelink), and service requirements. The same RB framework serves multiple functions including data transmission, reference signaling, and flexible adaptation to various numerical configurations, maintaining scheduling simplicity while improving efficiency across diverse scenarios.

AI summary
Provided are a data transmission method, apparatus and system. The data transmission method includes: configuring transmission resource configuration information, where the transmission resource configuration information includes configuration information about k RUs, each RU includes N subcarriers and M consecutive slots, and k, N, and M are integers greater than or equal to 1; and scheduling, through downlink control signaling, a transmission of at least one data transmission channel over the k RUs indicated by the transmission resource configuration information.
