A carrier management method, comprising: acquiring, by a terminal device, configuration information sent by a network device, wherein the configuration information is used for indicating whether to enable the terminal device to adopt a first processing manner; when the configuration information indicates that the terminal device is not enabled to adopt the first processing manner, controlling, by the terminal device during an active time of discontinuous reception, DRX, to process signal transmitted on a first carrier through a second processing manner different from the first processing manner; and when the configuration information indicates that the terminal device is enabled to adopt the first processing manner, controlling, by the terminal device when entering the active time of DRX, to process the signal transmitted on the first carrier through the first processing manner; wherein in the first processing manner, processing is stopped, within at least part of the active time, for at least part of the signal transmitted on the first carrier; and, in the second processing manner, the processing is maintained for the signal transmitted on the first carrier during the active time, and the maintained processing includes monitoring a configured control channel search space of the first carrier, characterized in that the method further comprises: during the active time of DRX that the terminal device enters, when the first processing manner is adopted for the first carrier to process the signal transmitted on the first carrier, receiving, through a second carrier, first indication information sent via a downlink control channel, wherein the first indication information is used for indicating exiting the first processing manner for the first carrier; and controlling, based on the first indication information, to exit the first processing manner for the first carrier, and processing, on the first carrier, the signal transmitted on the first carrier through the second processing manner, wherein the first carrier is a secondary carrier configured and activated by the terminal device; the second carrier is a primary carrier or another activated secondary carrier in the second processing manner. acquiring, by a terminal device, configuration information sent by a network device, wherein the configuration information is used for indicating whether to enable the terminal device to adopt a first processing manner;
