Engineering Contradiction Analysis
1Speed
If a large quantity of MIMO layers, high bandwidth, and plurality of carriers are configured for high-speed data transmission, then data transmission rate is improved, but terminal device overheating and power consumption increase
Solution Approach 1:
The patent implements dynamic adjustment of communication parameters (MIMO layers, bandwidth, carriers) based on real-time terminal device temperature monitoring. When overheating is detected, the system dynamically reduces the configuration scale to lower temperature, and when temperature is normal, it restores high-speed transmission configuration, creating a dynamic balance between transmission rate and thermal management
Solution Approach 2:
The system changes physical parameters (number of MIMO layers, bandwidth width, carrier quantity) based on temperature conditions. By adjusting these parameters according to terminal device thermal state, the system resolves the contradiction between maintaining high transmission rates and preventing overheating
2Speed
If a large quantity of MIMO layers, high bandwidth, and plurality of carriers are configured for high-speed data transmission, then data transmission rate is improved, but power consumption increases
Solution Approach 1:
The system dynamically adjusts communication configuration parameters based on power consumption thresholds and transmission requirements. When power consumption exceeds thresholds, the system reduces MIMO layers, bandwidth, or carrier quantity to lower power usage, and restores high-rate configuration when power levels are acceptable, achieving dynamic optimization between speed and energy efficiency
Solution Approach 2:
By changing communication parameters (MIMO layer count, bandwidth allocation, carrier activation) based on power consumption states, the system resolves the contradiction between maintaining high data transmission rates and controlling terminal device power consumption
3Temperature
If master base station and secondary base station both adjust communication parameters independently, then overheating problem can be resolved, but network coordination complexity increases
Solution Approach 1:
The master base station acts as an intermediary that receives temperature information from the terminal, determines the appropriate temperature threshold, and then instructs the secondary base station on parameter adjustments. This intermediary role centralizes the decision-making process while enabling coordinated action between base stations, reducing overall system complexity
Solution Approach 2:
The patent replaces independent mechanical-style adjustments by multiple base stations with a centralized control mechanism where the master base station directs parameter changes. This substitution of control architecture simplifies coordination by eliminating the need for complex inter-base-station negotiation protocols

AI summary
This application provides example information transmission methods and example apparatuses. One example method includes receiving, by a first network device, an overheating message sent by a terminal device, where the overheating message includes overheating assistance information, and where the overheating assistance information is used to indicate whether the terminal device is overheated. The first network device can then determine a second message based on the overheating assistance information, where the second message is used to indicate a second network device to adjust a communications parameter configured for the terminal device The first network device can then send the second message to the second network device.
