In some examples, the preemption and permission indication manager 1015 may determine that the control message indicates that the UE is to interpret future indications received from the base station and pertaining to the uplink transmissions on the carrier as permission indications. In some examples, the preemption and permission indication manager 1015 may fail to receive a permission indication in accordance with the control message indicating that the UE has permission to transmit the uplink transmission. In some examples, the communications manager 1005 may coordinate with a transmitter to drop the uplink transmission based on failing to receive the permission indication.
In some examples, the monitoring indication manager 1010 may receive a monitoring indication in the uplink grant indicating whether the UE is to monitor the second downlink control channel for the preemption indication or the permission indication, the monitoring indication being based on whether the uplink transmission is allowed to be preempted by another transmission. In some examples, the preemption and permission indication manager 1015 may monitor for the preemption indication or the permission indication in accordance with the monitoring indication.
