Abstract: Techniques are described for handling enhanced Mobile Broadband (eMBB) and Ultra Reliable Low Latency Communication (URLLC) simultaneous transmissions. For example, based on received downlink control information (DCI), user equipment (UE) can determine one or more behaviors to perform based on whether the DCI is related an enhanced mobile broadband (eMBB) service and/or an ultra-reliable low-latency communication (URLLC) service. The behaviors performed when the DCI is related to the eMBB service can be different than the behaviors performed when the DCI is related to the URLLC service.
