Method for Determining Maximum Transmit Power,Terminal, and Base Station

A method, comprising:

• receiving, by a terminal, N configuration parameters sent by a base station, wherein each of the configuration parameters indicates a limiting power corresponding to a type of feature information, the feature information comprises a power level or a service type, and N is greater than or equal to 1;
• and
• when the feature information indicated by the N configuration parameters comprises feature information of the terminal, determining, by the terminal, a maximum transmit power of the terminal according to a nominal transmit power corresponding to the feature information of the terminal, and a limiting power indicated by a configuration parameter corresponding to the feature information of the terminal, wherein the maximum transmit power is not less than a lower limit of the maximum transmit power and not greater than an upper limit of the maximum transmit power;
• when the feature information corresponding to the N configuration parameters does not comprise the feature information of the terminal, determining, by the terminal, a candidate limiting power according to a preset policy;
• and
• determining, by the terminal, the maximum transmit power according to the candidate limiting power and the nominal transmit power corresponding to the feature information of the terminal.

A terminal, comprising:

• a bus;
• and
• a processor, a memory, and a transceiver, that are each connected to the bus;
• wherein the memory is configured to store instructions, and the instructions are configured to be executed by the processor;
• wherein the transceiver is configured to receive N configuration parameters sent by a base station, wherein each of the N configuration parameters indicates a limiting power corresponding to a type of feature information, the feature information indicates a power level or a service type, and N is not less than 1;
• and
• wherein the processor is configured to:
• when the feature information indicated by the N configuration parameters comprises feature information of the terminal, determine a maximum transmit power of the terminal according to at least a nominal transmit power corresponding to the feature information of the terminal and a limiting power indicated by the configuration parameter corresponding to the feature information of the terminal, wherein the maximum transmit power is not less than a lower limit of the maximum transmit power and not greater than an upper limit of the maximum transmit power;
• and
• when the feature information corresponding to the N configuration parameters does not comprise the feature information of the terminal, determine a candidate limiting power according to a preset policy, and determine the maximum transmit power according to at least the candidate limiting power and the nominal transmit power corresponding to the feature information of the terminal.
