Slot Format Indication Method, Device, and System

A first user equipment (UE), comprising:

• a processor;
• and
• a non-transitory computer-readable storage medium storing a program to be executed by the processor, the program including instructions to:
• obtain first downlink control information (DCI), wherein the first DCI comprises a first slot format indication (SFI) and at least one second SFI, wherein the first SFI is an SFI of at least one of the first UE or a group in which the first UE is disposed, and wherein the second SFI is an SFI of at least one of a group in which the second UE is disposed or a second UE paired with the first UE;
• and
• obtain the first SFI and the at least one second SFI from the first DCI according to first indication information, wherein the first indication information indicates a location of the first SFI in the first DCI and further indicates a location of the at least one second SFI in the first DCI;
• and
• determine, according to the first SFI and the at least one second SFI that are obtained by the obtaining unit, to perform full-duplex communication.

A computer storage medium, storing a computer program for execution by a processor of a first user equipment (UE), the computer program including instructions that, when executed, cause the processor to perform:

• obtaining first downlink control information (DCI), wherein the first DCI comprises first slot format indication (SFI) and at least one second SFI, wherein the first SFI is at least one of an SFI of the first UE or an SFI of a group in which the first UE is disposed, and wherein the second SFI is at least one of an SFI of second UE paired with the first UE or an SFI of a group in which the second UE is disposed;
• obtaining the first SFI and the at least one second SFI from the first DCI according to first indication information, wherein the first indication information indicates a location of the first SFI in the first DCI and further indicates a location of the at least one second SFI in the first DCI;
• and
• determining, according to the first SFI and the at least one second SFI, to perform full-duplex communication.
