1. A dual Subscriber Identity Module (SIM) communication method for a terminal, wherein dual SIM cards share a main antenna and a diversity antenna, the dual SIM cards comprise a first SIM card and a second SIM card, and the method comprises:
determining whether slots of the dual SIM cards are aligned; and
when the slots of the dual SIM cards are not aligned, controlling the first SIM card and the second SIM card to communicate in a first manner, wherein
the controlling the first SIM card and the second SIM card to communicate in a first manner comprises:
within an uplink slot of the second SIM card, controlling the second SIM card to transmit a signal by using the main antenna;
for an odd-numbered downlink slot of the second SIM card, controlling the second SIM card to receive a signal by using the diversity antenna within the entire odd-numbered downlink slot, and controlling the first SIM card to transmit a signal by using the main antenna in a preceding time period within the odd-numbered downlink slot and to receive a signal by using the main antenna in a later time period within the odd-numbered downlink slot; and
for an even-numbered downlink slot of the second SIM card, in a preceding time period within the even-numbered downlink slot, controlling the second SIM card to receive a signal by using the diversity antenna and controlling the first SIM card to transmit a signal by using the main antenna, and in a later time period within the even-numbered downlink slot, controlling the first SIM card to receive a signal by using the main antenna, wherein
the uplink slot of the second SIM card and a downlink slot of the second SIM card are alternated.
