Solution Approach 1:

The patent introduces an intermediary adjustment mechanism that manages the interaction between different communication bands. This intermediary system monitors interference levels and dynamically adjusts transmission and radiation paths, isolation degrees, and band allocations to mediate between the need for high data transmission efficiency and the need to maintain communication sensitivity across multiple bands.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent implements dynamic adjustment of communication link parameters including real-time switching between transmission paths, dynamic control of radiation paths, and adaptive modification of isolation degrees. This dynamic approach allows the system to optimize performance for each specific operating condition while maintaining reliability across multiple communication bands.

AI summary

Provided are a communication link adjustment method and apparatus, an electronic device, and a readable medium. The method includes that: interference information of a communication link under a multi-connection scenario is acquired; whether an isolation degree value of the communication link exceeds a range defined by a preset isolation degree threshold is determined according to the interference information; and in a case where the isolation degree value of the communication link exceeds the range defined by the preset isolation degree threshold, the communication link is adaptively adjusted according to the isolation degree value and an isolation degree adjustment mapping table until the isolation degree value meets a requirement for a wireless performance index, wherein the isolation degree adjustment mapping table includes a mapping relationship between isolation degree values and path parameters.
