Methods and devices for reducing temperature for user equipment

A method for reducing temperature for user equipment (UE), comprising:

• receiving first configuration information from a target base station;
• and
• updating radio communication parameter configuration of the UE based on the first configuration information to reduce temperature for the UE,
• wherein the target base station sends the first configuration information to the UE by:
• receiving an X2 interface setup request from a source base station, wherein the X2 interface setup request carries capability information indicating that the source base station is capable of reducing the temperature for the UE by updating configuration information;
• transmitting an X2 interface setup response to the source base station to establish an X2 interface, wherein the X2 interface setup response carries capability information indicating that the target base station is capable of reducing the temperature for the UE by updating the configuration information;
• receiving a handover request from the source base station, wherein the handover request carries at least one of configuration information expected by the UE and indication information indicating that the UE overheats;
• and
• sending the first configuration information to the UE based on the handover request, wherein the first configuration information is configured for the UE to update the radio communication parameter configuration to reduce the temperature of the UE, and the first configuration information is the same as or different from the configuration information expected by the UE.

A first base station, comprising:

• a processor;
• and
• a memory configured to store an instruction executable by the processor,
• wherein the processor is configured to:
• receive an X2 interface setup request from a second base station as a source base station, wherein the X2 interface setup request carries capability information indicating that the source base station is capable of reducing temperature for user equipment (UE) by updating configuration information;
• transmit an X2 interface setup response to the source base station to establish an X2 interface, wherein the X2 interface setup response carries capability information indicating that the first base station is capable of reducing the temperature for the UE by updating the configuration information;
• receive a handover request from the source base station, wherein the handover request carries at least one of configuration information expected by UE and indication information indicating that the UE overheats;
• and
• send first configuration information to the UE based on the handover request, wherein the first configuration information is configured for the UE to update its own radio communication parameter configuration for reducing the temperature of the UE, and the first configuration information is the same as or different from the configuration information expected by the UE.

User equipment (UE), comprising:

• a processor;
• and
• a memory configured to store an instruction executable by the processor,
• wherein the processor is configured to:
• receive first configuration information from a target base station;
• and
• update radio communication parameter configuration of the UE based on the first configuration information to reduce temperature for the UE,
• wherein the target base station sends the first configuration information to the UE by:
• receiving an X2 interface setup request from a source base station, wherein the X2 interface setup request carries capability information indicating that the source base station is capable of reducing the temperature for the UE by updating configuration information;
• transmitting an X2 interface setup response to the source base station to establish an X2 interface, wherein the X2 interface setup response carries capability information indicating that the target base station is capable of reducing the temperature for the UE by updating the configuration information;
• receiving a handover request from the source base station, wherein the handover request carries at least one of configuration information expected by the UE and indication information indicating that the UE overheats;
• and
• sending the first configuration information to the UE based on the handover request, wherein the first configuration information is configured for the UE to update the radio communication parameter configuration to reduce the temperature of the UE, and the first configuration information is the same as or different from the configuration information expected by the UE.
