Solution Overview

Problem

Current wireless communication systems face challenges in efficiently managing sounding reference signal (SRS) resource sets, particularly in supporting multiple configurations with different parameters, which increases processing complexity for user equipment (UE) and network entities.

Innovation Solution

Implementing a method where user equipment (UE) and network entities can receive and transmit SRS resource set configurations with a subset of parameters being the same and another subset being different, allowing for flexible configuration without increasing processing burden, by using DCI formats like DCI format 0_2 and DCI format 1_2, which support additional SRS resource sets with 'codebook' or 'non-codebook' usage.

1Adaptability or versatility

If multiple SRS resource set configurations with different parameters are supported, then adaptability is improved, but device complexity increases

Engineering Contradiction:

Improveconfiguration flexibilityVSAvoidprocessing complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The SRS resource set configuration is segmented into two distinct subsets: a first subset of parameters that remains common across multiple configurations, and a second subset of parameters that varies between configurations. This segmentation allows the network to configure multiple SRS resource sets with different parameters while the UE only needs to process the varying second subset, significantly reducing processing complexity while maintaining configuration flexibility and adaptability.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If multiple SRS resource set configurations are transmitted, then adaptability is improved, but loss of time increases due to additional processing

Engineering Contradiction:

Improveconfiguration flexibilityVSAvoidprocessing time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

By segmenting configuration parameters into common and variable subsets, the UE can efficiently process multiple SRS resource set configurations by focusing only on the varying second subset parameters, reducing processing time while maintaining adaptability

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The network pre-configures the first subset of common parameters that apply to multiple SRS resource sets. This preliminary configuration allows the UE to avoid re-processing identical parameters for each configuration, significantly reducing processing time when multiple configurations are transmitted while maintaining full adaptability

Inventive Principle:

Principle #10Preliminary action

AI summary

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network entity, a first sounding reference signal (SRS) resource set configuration that indicates a first set of parameters. The UE may receive, from the network entity, a second SRS resource set configuration with a same usage as the first SRS resource set configuration that indicates a second set of parameters, wherein a subset of parameters are different between the first set of parameters and the second set of parameters. Numerous other aspects are described.
