Uplink SRS Time-Domain Bundling for Better Channel Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G NR technologies face inefficiencies in SRS transmissions, particularly in determining optimal frequency regions for channel quality assessment, leading to suboptimal resource allocation and reduced coverage.
Innovation Solution
A method and apparatus for a UE to determine whether to bundle SRS resources based on bundling factors, allowing for time-domain bundling of SRS transmissions to enhance SRS capability and coverage by optimizing resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If SRS transmissions are performed without time-domain bundling, then transmission simplicity is maintained, but channel quality assessment accuracy and coverage are reduced
Solution Approach 1:
The patent combines multiple SRS transmissions in the time domain by bundling them together. The UE determines whether to bundle SRS resources based on bundling factors, merging multiple SRS transmissions into a single bundled transmission to improve channel quality assessment accuracy while managing transmission complexity through standardized bundling procedures
2Productivity
If SRS resources are allocated without optimization, then resource allocation simplicity is maintained, but resource utilization efficiency and coverage are reduced
Solution Approach 1:
The patent introduces dynamic resource allocation for SRS transmissions. The UE dynamically determines whether to bundle SRS resources based on bundling factors such as channel conditions and transmission requirements. This dynamic approach optimizes resource utilization efficiency by adapting resource allocation to current network conditions while maintaining manageable complexity through standardized decision-making procedures

AI summary
In an aspect, the present disclosure includes a method, apparatus, and computer readable medium for wireless communications for determining, by a user equipment (UE), whether to time-domain bundle two sounding reference signal (SRS) transmissions of at least one of a same SRS resource or of two different SRS resources based at least on one or more bundling factors, wherein an SRS resource corresponding to the same SRS resource or the two different SRS resources is a collection of SRS transmissions over one or more slots, and wherein each SRS transmission of the collection of SRS transmissions occupies one or more orthogonal frequency division multiplexing (OFDM) symbols; and transmitting, to the network entity, the time-domain bundled two SRS transmissions of the at least one of same SRS resource or of two different SRS resources based on a determination to time-domain bundle the two SRS transmissions.
