Frequency Hopping Area Segmentation for M-PUSCH and PUSCH Conflict Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing frequency hopping processing methods, a resource conflict can occur when Machine Type Communication (M-PUSCH) frequency hopping of an extended Transmission Time Interval (TTI) and Physical Uplink Shared Channel (PUSCH) frequency hopping of a 1 ms TTI are performed simultaneously, as they often occupy the same resource.
Innovation Solution
A method and apparatus that allow user equipment to receive frequency hopping information for an extended TTI, determining a frequency hopping area that does not overlap with the frequency hopping area of a normal TTI, thereby avoiding resource conflicts by hopping into a corresponding M-PUSCH frequency hopping area according to a preset pattern, ensuring that M-PUSCH frequency hopping of the extended TTI does not overlap with PUSCH frequency hopping.

Engineering Contradiction Analysis
1Productivity
If M-PUSCH frequency hopping of extended TTI and PUSCH frequency hopping of 1 ms TTI are performed simultaneously using existing frequency hopping processing methods, then both channels can transmit data, but resource conflicts occur as they occupy the same frequency resources
Solution Approach 1:
The frequency hopping area is segmented into separate regions for M-PUSCH and PUSCH. The M-PUSCH frequency hopping area is configured to be non-overlapping with the PUSCH frequency hopping area, thereby dividing the frequency resources into distinct segments that prevent resource conflicts while maintaining data transmission for both channels
Solution Approach 2:
Different frequency hopping parameters are assigned to M-PUSCH and PUSCH based on their specific requirements. The M-PUSCH is configured with extended TTI and specific frequency hopping offsets that differ from PUSCH parameters, creating locally optimized frequency hopping behavior for each channel type that avoids resource overlap
2Quantity of substance
If frequency hopping area for extended TTI is not properly configured, then resource utilization is maximized, but resource conflicts occur between M-PUSCH and PUSCH frequency hopping
Solution Approach 1:
The frequency hopping area for M-PUSCH is pre-configured with specific parameters including frequency hopping offsets and resource block allocations that are calculated to be non-overlapping with PUSCH areas. This preliminary configuration of frequency hopping parameters prevents resource conflicts before transmission occurs
Solution Approach 2:
The frequency hopping configuration extends into the time dimension by using extended TTI for M-PUSCH while maintaining 1 ms TTI for PUSCH. This temporal dimension differentiation, combined with frequency domain segmentation, creates a multi-dimensional resource allocation scheme that increases overall resource utilization without causing conflicts

AI summary
A frequency hopping processing method and apparatus are disclosed, where user equipment receives frequency hopping information, which is sent by a network device, of an extended transmission time interval (TTI); and determines a frequency hopping area of the extended TTI according to the frequency hopping information of the extended TTI. The frequency hopping area of the extended TTI and a frequency hopping area of a normal TTI do not overlap in frequency, and during M-PUSCH frequency hopping of each extended TTI, the user equipment can hop into a corresponding M-PUSCH frequency hopping area according to a preset frequency hopping pattern, and does not hop into a PUSCH frequency hopping area, so that a resource conflict does not exist when M-PUSCH frequency hopping of an extended TTI and PUSCH frequency hopping of a 1 ms TTI are performed at the same time.
