Solution Overview

Problem

Existing SRS resource configurations in New Radio (NR) networks are not flexible enough, leading to inefficient energy consumption and user experience issues due to the need to utilize all transmitting channels in terminals.

Innovation Solution

The method involves configuring SRS resources based on the terminal's antenna switching capability, allowing for flexible SRS port allocation, such as N≤X, to support fallback modes like NTYR, reducing power consumption and improving user experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If all transmitting channels are put into use for SRS resources, then the antenna switching capability is fully utilized, but the power consumption increases and energy saving is reduced

Engineering Contradiction:

Improveantenna switching capabilityVSAvoidpower consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent applies dynamics by making the SRS resource configuration flexible and adjustable rather than fixed. The network side can dynamically configure different numbers of SRS ports (N≤X) based on actual communication needs, allowing the terminal to adaptively switch between using all transmitting channels or fewer channels, thus balancing antenna switching capability with power consumption.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of SRS port count from a fixed value to a variable parameter N where N≤X. This parameter change allows the system to adjust the number of active transmitting channels according to different scenarios, enabling the terminal to reduce power consumption by using fewer channels when full antenna switching capability is not required.
