Solution Overview

Problem

The existing Maximum Sensitivity Degradation (MSD) value in user equipment (UE) for 3GPP LTE is excessively large, leading to inefficient communication performance.

Innovation Solution

A UE and base station method involving transceivers, processors, and memory to transmit and receive signals with lower MSD, including transmitting a random access preamble, receiving a response, and scheduling based on lower MSD information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the previously defined MSD value is used in UE, then device compatibility is maintained, but communication efficiency deteriorates due to excessively large MSD value

Engineering Contradiction:
Improvecommunication efficiencyVSAvoidcommunication performance
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent applies dynamics by making the MSD value adjustable rather than fixed. The UE determines its actual MSD capability and dynamically reports this value to the base station, allowing the system to adapt the MSD parameter based on the specific UE's performance characteristics rather than using a static, overly conservative value for all devices.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements parameter changes by modifying the MSD value from a fixed previously defined parameter to a dynamic parameter that reflects the actual UE capability. The UE calculates its specific MSD value based on its receiver performance and reports this updated parameter to the base station, enabling more accurate resource allocation and scheduling decisions.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If UE performance is improved, then communication capability is enhanced, but the previously defined MSD value becomes too large and causes inefficient communication

Engineering Contradiction:
ImproveUE performanceVSAvoidcommunication efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent implements feedback by having the UE measure and determine its actual MSD capability, then report this value back to the base station. This feedback loop allows the network to recognize the UE's true performance capability and adjust scheduling and resource allocation accordingly, preventing the waste associated with using an overly conservative MSD value.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent applies preliminary action by having the UE determine and report its MSD capability in advance before actual data transmission begins. This allows the base station to pre-configure appropriate scheduling parameters and resource allocation strategies based on the UE's reported capability, optimizing communication efficiency from the outset rather than using default conservative settings.

Inventive Principle:
Principle #10Preliminary action

AI summary

A disclosure of the present specification provides a UE. The UE comprises: one or more transceivers; one or more processors; and one or more memories that store instructions and may be operatively connected to the one or more processors, wherein an operation performed on the basis that the instructions are executed by the one or more processors may comprise the steps of: transmitting a random access preamble to a base station; receiving, from the base station, a response to the random access preamble; transmitting, to the base station, information related to lower MSD; receiving a downlink signal; and transmitting an uplink signal.
