PUSCH Intra-Slot Frequency Hopping Within BWP Resource Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication technologies lack a scheme for intra-slot frequency hopping (FH) when a Physical Uplink Shared Channel (PUSCH) is transmitted within an uplink subband and a normal bandwidth part (BWP) in the same time slot, leading to potential exceedance of frequency domain resource ranges.
Innovation Solution
A frequency hopping processing method that involves configuring and determining target offsets for adjacent hops based on available frequency domain offsets, ensuring they remain within the uplink BWP or subband resource ranges during intra-slot frequency hopping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If intra-slot frequency hopping is performed when PUSCH is transmitted within uplink subband and normal BWP in the same time slot, then frequency diversity gain and transmission performance are improved, but frequency domain resources may exceed the allocated BWP or subband limits
Solution Approach 1:
The patent dynamically adjusts the frequency domain offset parameter for frequency hopping based on the specific scenario (whether first hop is in subband or BWP). By changing the offset parameter values adaptively, the system ensures that the second hop remains within the appropriate frequency boundaries while still achieving frequency diversity gain.
Solution Approach 2:
The patent applies different frequency domain offset configurations for different local scenarios: when the first hop is in the uplink subband, a specific offset range is used; when the first hop is in the normal BWP, a different offset configuration is applied. This localized parameter adjustment ensures boundary compliance in each specific context.
2Ease of manufacture
If frequency hopping is configured without considering the interaction between uplink subband and normal BWP, then configuration simplicity is maintained, but frequency resource allocation accuracy deteriorates
Solution Approach 1:
The patent segments the frequency hopping configuration into distinct cases based on the location of the first hop (either in uplink subband or in normal BWP). Each segment has its own offset configuration rules, allowing precise control over frequency resource allocation while maintaining clear configuration procedures through case-based differentiation.
Data Source
AI summary
The present disclosure provides a frequency hopping processing method and device. A terminal receives one or more first offsets configured for the terminal by a base station. The first offset is an available frequency domain offset corresponding to two adjacent hops when the terminal transmits a PUSCH in a frequency hopping mode within a frequency domain resource range occupied by an uplink BWP. When the two adjacent hops are located in the same first time unit in the time domain and the occupied frequency domain resource meets a specified condition, the terminal determines a target offset of the two adjacent hops at least based on the first offsets; and based on the target offset, the terminal transmits the PUSCH to the base station in the frequency hopping mode in the first time unit.
