Engineering Contradiction Analysis
1Productivity
If an STR operation is performed in an MLO terminal to enable simultaneous data transmission and reception using multiple Links, then communication efficiency and throughput are improved, but inter-link interference occurs that degrades signal quality
Solution Approach 1:
The patent applies preliminary action by having the reception unit measure and store interference information from other Links before data reception occurs. The communication control unit then uses this pre-measured interference information to determine appropriate reception parameters (such as modulation and coding scheme) that account for the expected interference, thereby enabling the STR operation to proceed efficiently while compensating for the known interference conditions.
2Object-affected harmful factors
If a hardware configuration is employed to reduce inter-link interference, then signal quality may be improved, but not all MLO terminals can sufficiently remove the interference and the degree of influence varies by implementation
Solution Approach 1:
The patent implements feedback by having the reception unit continuously measure interference information from other Links and feed this information back to the communication control unit. The control unit then adjusts reception parameters based on this real-time feedback, creating a closed-loop system that adapts to varying interference conditions. This software-based feedback mechanism provides a universal solution that can be implemented across different MLO terminal hardware configurations.
3Device complexity
If transmission parameters are not adjusted based on interference information, then device complexity is reduced, but communication quality deteriorates due to unmitigated inter-link interference
Solution Approach 1:
The patent applies self-service by enabling the MLO terminal to automatically measure, evaluate, and adjust its own reception parameters based on internally generated interference information. The communication control unit autonomously determines appropriate reception parameters using the interference measurements taken by the reception unit, without requiring external intervention or complex centralized control, thereby maintaining relatively simple device architecture while improving communication reliability.

AI summary
The present technology relates to a communication apparatus and an information processing method that make it possible to appropriately reduce inter-link interference. The communication apparatus according to the present technology acquires, in a case of simultaneously performing transmission and reception of a data signal with another communication apparatus using a plurality of Links, first interference information concerning interference between Links occurring in the other communication apparatus from the other communication apparatus, and decides a transmission parameter to be used by the other communication apparatus for transmission of a data signal on a basis of the first interference information and second interference information concerning interference between the Links occurring in the communication apparatus. The present technology is applicable to a wireless communication system.
