Configurable Data Mapping Sequence for NR Distribution Flexibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing data processing methods in LTE systems are limited to centralized data distribution in the time domain, which is not adaptable to the diverse application scenarios of the new radio (NR) system, failing to accommodate both centralized and decentralized data distribution manners.
Innovation Solution
A data processing method that includes interleaving and mapping processing in specific sequences, such as frequency-domain mapping before time-domain mapping, or time-domain mapping before frequency-domain mapping, to achieve centralized or decentralized data distribution in the time, space, and frequency domains, allowing for multiple application scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If only mapping processing is performed in a fixed mapping sequence (space-domain, then frequency-domain, then time-domain), then the data distribution manner is centralized in time domain which facilitates fast demodulation, but the system cannot adapt to diverse application scenarios requiring both centralized and decentralized data distribution
Solution Approach 1:
The patent applies dynamics by making the mapping sequence configurable and adaptable rather than fixed. The network device can dynamically select different mapping sequences (e.g., space-domain then frequency-domain then time-domain for centralized distribution, or frequency-domain then time-domain for decentralized distribution) based on different application scenarios and service requirements, enabling the system to transition between centralized and decentralized data distribution modes as needed
Solution Approach 2:
The patent changes the parameter of mapping sequence order to achieve different data distribution manners. By adjusting the sequence in which mapping operations are performed (changing the order parameters of space-domain, frequency-domain, and time-domain mapping), the system can transform between centralized and decentralized data distribution to suit different NR application scenarios without hardware modification
2Adaptability or versatility
If interleaving processing is added to achieve decentralized data distribution, then adaptability to diverse scenarios is improved, but the processing complexity and computational overhead increase
Solution Approach 1:
The patent applies universality by designing a unified mapping framework that can perform both centralized and decentralized data distribution through configurable mapping sequences. The same layer mapping module can universally handle different distribution manners by adjusting the mapping sequence parameters, eliminating the need for separate interleaving processing modules and reducing overall system complexity while maintaining data distribution flexibility

AI summary
Embodiments of this application disclose a data processing method and an apparatus thereof. The method includes: processing, by a network device, to-be-transmitted data to obtain a data distribution manner, where the processing includes at least one of interleaving processing and mapping processing that is performed in a mapping sequence; the data distribution manner is used to indicate distribution of data from a same code block; and when the processing includes only mapping processing performed in a mapping sequence, the mapping sequence does not include a mapping sequence in which space-domain mapping is first performed, frequency-domain mapping is then performed, and time-domain mapping is finally performed; sending, the to-be-transmitted data distributed in the data distribution manner; receiving, by a terminal device, processed to-be-transmitted data; and determining, a data distribution manner, and performing de-processing on the processed to-be-transmitted data in the data distribution manner, to obtain the to-be-transmitted data.
