Solution Overview

Problem

Existing wireless communication systems face challenges in mitigating maximum sensitivity degradation (MSD) due to interference, which affects receiver sensitivity and downlink communication performance, as the network lacks information on the terminal's capability to mitigate MSD, leading to ineffective mitigation strategies.

Innovation Solution

A communication method where a terminal determines its capability to mitigate MSD for a specific band combination and sends information to the network, allowing the network to adjust scheduling and configurations to effectively manage MSD.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the network does not have information on terminal's MSD mitigation capability, then the system complexity is low, but the receiver sensitivity deteriorates due to ineffective MSD mitigation

Engineering Contradiction:
Improvereceiver sensitivityVSAvoidMSD mitigation capability information
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The terminal device determines its MSD mitigation capability in advance and sends this capability information to the network device before actual communication occurs. This preliminary action ensures the network has the necessary information to make informed scheduling decisions, thereby maintaining receiver sensitivity without adding complex real-time feedback mechanisms.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If the terminal sends MSD mitigation capability information to the network, then the receiver sensitivity is improved, but the communication protocol complexity increases

Engineering Contradiction:
Improvereceiver sensitivityVSAvoidcommunication protocol complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The capability information is sent once in advance through existing signaling mechanisms (RRC signaling, MAC CE, or uplink data channels) rather than requiring continuous real-time exchange. This approach improves receiver sensitivity while minimizing protocol complexity by reusing established communication pathways.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The MSD mitigation capability information serves as an intermediary parameter that enables the network to adjust scheduling strategies. By introducing this single capability indicator, the system achieves improved receiver sensitivity without requiring complex multi-parameter negotiation protocols.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If the network adjusts scheduling based on terminal capability information, then the MSD is effectively mitigated, but the network operation complexity increases

Engineering Contradiction:
ImproveMSD mitigation effectivenessVSAvoidnetwork operation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The network applies different scheduling strategies tailored to specific terminal capabilities rather than using a uniform approach for all terminals. Terminals with MSD mitigation capability receive different treatment than those without, optimizing performance for each case while keeping the overall system manageable through capability-based differentiation.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

By receiving capability information in advance, the network can pre-configure appropriate scheduling strategies for each terminal type. This preliminary knowledge allows the network to simplify real-time operations by avoiding complex on-the-fly decisions, thereby effectively mitigating MSD without excessive operational complexity.

Inventive Principle:
Principle #10Preliminary action

AI summary

A communication method includes determining a capability of mitigating maximum sensitivity degradation (MSD) for a first band combination. The first band combination includes a first band and a second band. A band number of the first band is different from a band number of the second band. The communication method also includes sending first information. The first information indicates the capability of mitigating the MSD for the first band combination.
