Multi-slot slot format indicator (SFI) extensions

An apparatus comprising:

• a transceiver configured to:
• communicate, with a second wireless communication device, a first slot format indicator (SFI) for a first set of slots, via a first DCI message using a DCI format for indicating slot format on group common-physical downlink control channel (GC-PDCCH);
• communicate, with the second wireless communication device, a second SFI for a second set of slots, via a second DCI message using the DCI format, the second set of slots overlapping with the first set of slots in at least one of time or frequency;
• and
• communicate, with the second wireless communication device, a communication signal based on at least one of the first SFI or the second SFI.

A non-transitory computer-readable medium having program code recorded thereon, the program code comprising:

• code for causing a first wireless communication device to communicate, with a second wireless communication device, a first slot format indicator (SFI) for a first set of slots, via a first DCI message using a DCI format for indicating slot format on group common-physical downlink control channel (GC-PDCCH);
• code for causing the first wireless communication device to communicate, with the second wireless communication device, a second SFI for a second set of slots, via a second DCI message using the DCI format, the second set of slots overlapping with the first set of slots in at least one of time or frequency;
• and
• code for causing the first wireless communication device to communicate, with the second wireless communication device, a communication signal based on at least one of the first SFI or the second SFI.
