Interrupted transmission indication for new radio (nr)

Abstract

Technology for a user equipment (UE) operable for interrupted transmission indication is disclosed. The UE can be configured to decode, at the UE, control information carried by a physical downlink control channel (PDCCH) in a first active bandwidth part (BWP). The UE can be configured to identify, at the UE, an interrupted transmission (INT) indicator from the control information in the first active BWP. The UE can be configured to determine, at the UE, a location of an INT indicator for a second active BWP from the INT indicator for the first active BWP.
