Abstract
The described techniques relate to techniques for determining transmission opportunities and utilization of uplink resources by a user equipment (UE) in communication with a base station. In some examples, a base station may transmit a slot configuration to a UE. The slot configuration may indicate the communication link direction (uplink, downlink, or flexible) associated with each symbol in a given slot. A dynamic slot configuration may indicate which of the flexible symbols are uplink symbols and which are downlink symbols and the UE may determine uplink transmission opportunities based on the slot configuration, the dynamic slot configuration, and a grant free uplink type associated with the UE. The UE may transmit an uplink data message to the base station using the determined set of uplink transmission resources.
