Abstract
A method is provided. The method includes receiving, by a terminal, N configuration parameters sent by a base station. The method also includes, when 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 at least 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.
Claims20
A method, comprising:
- receiving, by a terminal, one or more configuration parameters sent by a base station, wherein each of the one or more configuration parameters comprises:
- a terminal attribute, wherein the terminal attribute comprises a power class type or a service type;
- and
- a power limit corresponding to the terminal attribute;
- determining, by the terminal, whether at least one terminal attribute comprised by the one or more configuration parameters matches a terminal attribute of the terminal;
- in response to determining that at least one terminal attribute comprised by the one or more configuration parameters matches the terminal attribute of the terminal, determining, by the terminal, a maximum transmit power for the terminal, the maximum transmit power being determined according to at least one power limit corresponding to the at least one terminal attribute, and according to a nominal transmit power 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
- in response to determining that no terminal attribute comprised in the one or more configuration parameters matches the terminal attribute of the terminal, determining, by the terminal, the maximum transmit power for the terminal according to a candidate power limit indicated by a preset policy, and
- the nominal transmit power of the terminal.

A terminal, comprising:
- a bus;
- a processor, coupled to the bus;
- a transceiver, coupled to the bus, and configured to receive N configuration parameters sent by a base station, wherein N is an integer greater than or equal to 1, and wherein each configuration parameter of the N configuration parameters comprises:
- a terminal attribute, wherein the terminal attribute comprises a power class type or a service type;
- and
- a power limit corresponding to the terminal attribute;
- and
- a non-transitory computer-readable storage medium storing a program to be executed by the processor, the program including instructions for:
- determining whether at least one terminal attribute comprised in the N configuration parameters matches a terminal attribute of the terminal;
- in response to determining that at least one terminal attribute comprised in the N configuration parameters matches the terminal attribute of the terminal, determining a maximum transmit power of the terminal, the maximum transmit power being determined according to at least one power limit corresponding to the at least one terminal attribute, and according to a nominal transmit power 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
- in response to determining that no terminal attribute comprised in the N configuration parameters match the terminal attribute of the terminal, determining the maximum transmit power for the terminal according to a candidate power limit indicated by a preset policy, and the nominal transmit power of the terminal.
