The present application relates to slot format indicator signaling in wireless communication systems. For example, a network entity may configure a slot format to include one or more symbol partitions and a transmission assignment for each of the one or more symbol partitions, and communicate with to at least one UE according to the configured slot format. In another example, a UE may configure at least one slot format according to at least one of a semi-static configuration via a broadcast or unicast transmission, or a dynamic configuration via a group common physical downlink control channel (GC-PDCCH), and communicate with the network entity according to the slot format.
