In a specific embodiment, the number of carriers is 3, and the carriers are configured as one anchor carrier and two non-anchor carriers, and it should be understood by those skilled in the art that in the context of multiple carriers in the present application, each carrier is a Component Carrier (CC) in carrier aggregation, in this example, the method of the present application includes:
the base station sends a low power consumption mode configuration message to the mobile terminal, wherein the low power consumption mode configuration message comprises the configuration of a low power consumption mode on a carrier A, the configuration of a low power consumption mode on a carrier B and the configuration of a low power consumption mode on a carrier C, and the configuration of the low power consumption mode on the carrier A, the configuration of the low power consumption mode on the carrier B and the configuration of the low power consumption mode on the carrier C are different; in one example, the base station sends a low power consumption mode configuration message to the mobile terminal through RRC signaling, as shown in fig. 2;
if the base station is to send downlink data of low priority, the base station determines signal quality on carrier a, signal quality on carrier B, and signal quality on carrier C; in one example, low priority downlink data may refer to data that is not sensitive to latency, e.g., some data is not sensitive to 1s or even 5s transmission latency, which may be defined as low priority data;
if the signal quality on the carrier A is determined to be the highest, the base station sends a combined wake-up signal A to the mobile terminal on the carrier A, wherein the combined wake-up signal A comprises one of the following items: a wake-up command a1 for waking up the mobile terminal to start listening for downlink control information on carrier a, a wake-up command B1 for waking up the mobile terminal to start listening for downlink control information on carrier B, and a wake-up command C1 for waking up the mobile terminal to start listening for downlink control information on carrier C; those skilled in the art will appreciate that if the base station transmits the combined wake-up signal a to the mobile terminal on carrier a, the base station no longer transmits the combined wake-up signal B to the mobile terminal on carrier B and no longer transmits the combined wake-up signal C to the mobile terminal on carrier C; in the prior art similar to the background art, the low power consumption mode in the multi-carrier scenario generally is that a base station requires a UE to execute the low power consumption mode on one carrier, periodically monitor a PDCCH message or a wake-up signal (WUS), and simultaneously require the UE to continuously not monitor the PDCCH message on other component carriers, and only after the UE monitors the PDCCH message or the wake-up signal on a predetermined carrier, the UE determines whether the PDCCH message needs to be monitored on other component carriers according to a scheduling message on the predetermined carrier; in the technology, the base station may schedule a message on a carrier B, but the base station still needs to send a wake-up signal on the carrier A, then sends a scheduling message on the carrier A, and then can send a message to the UE on the carrier B, the operation delay is large, and for a scene of aggregation of three carriers and more carriers, the base station can respectively activate other carriers by sending scheduling information on the carrier A for many times, so that the information transmission redundancy is large and the time delay is large; preferably, the wake-up command a1, the wake-up command B1, and the wake-up command C1 have different sizes, and in one embodiment, the size of the wake-up command may be changed by adding a redundant bit, and the wake-up commands with different sizes help the mobile terminal side to avoid a listening error caused by a decoding error; the wake-up command A1, the wake-up command B1 and the wake-up command C1 are sent simultaneously in one message, so that redundant overhead can be reduced, for example, if the wake-up commands are sent in three times respectively, redundant messages such as three sets of information headers and three sets of CRC are needed, and if the three information are combined into one message to be sent, only one header and one set of CRC are needed for one message, so that the decoding of the whole system is complex, but the transmission efficiency is improved;

wherein the wake command a2, the wake command B2, and the wake command C2 have different sizes;
if the signal quality on the carrier C is determined to be the highest, the base station sends a combined wake-up signal C to the mobile terminal on the carrier C, wherein the combined wake-up signal C comprises one of the following items: a wake-up command a3 for waking up the mobile terminal to start listening for downlink control information on carrier a, a wake-up command B3 for waking up the mobile terminal to start listening for downlink control information on carrier B, and a wake-up command C3 for waking up the mobile terminal to start listening for downlink control information on carrier C;

In this embodiment, the method of the present invention can bring a gain of power consumption reduction, and in terms of probability, the highest probability of the signal quality of the carrier a is 33%, and in the present application, the base station is required to transmit the combined wake-up signal on different carriers in the order of the necessary existence time, and it is assumed that the transmission of the combined wake-up signal a on the carrier a occurs first, and at this time, the mobile terminal has 33% of chances to hear the combined wake-up signal a when monitoring the carrier a first, and if the mobile terminal hears the combined wake-up signal a when monitoring the carrier a first, the mobile terminal does not need to monitor the combined wake-up signals B and C transmitted later, so that the mobile terminal can further save electric energy.
In a preferred embodiment, the method further comprises:
if the base station needs to send the downlink data with high priority, the base station determines the sequence of the sending time of the combined awakening signal on the carrier A, the sending time of the combined awakening signal on the carrier B and the sending time of the combined awakening signal on the carrier C; in one embodiment, the high priority data may be latency sensitive data;
