Abstract
Certain aspects of the present disclosure provide techniques for a slot format indicator (SFI) and slot aggregation level indication in a group common physical downlink control channel (GC PDCCH) and conflict handling for the SFI. According to certain aspects, a method of wireless communication by a base station (BS) is provided. The BS can determine a slot aggregation level and a format of the aggregated slots and send a downlink control channel including a SFI indicating the format of the aggregated slot and an indication of the slot aggregation level. The UE can receive the downlink control channel including the SFI and the indication of the slot aggregation level and the UE can determine a format of a current slot based on the received SFI and slot aggregation level.
