摘要

Methods, systems, and devices for wireless communication are described. In one example, a base station may dynamically configure a user equipment (UE) to monitor or avoid monitoring for a preemption indication. Accordingly, the UE may have a lower chance of monitoring for a preemption indication when it is unlikely that an uplink or downlink transmission will be preempted. In another example, a base station may transmit a control message indicating whether future indications received from the base station are to be interpreted as preemption indications or permission indications. Accordingly, the base station may choose to use either preemption indications or permission indications (e.g., based on the probability of collisions between mobile broadband (MBB) and low latency transmissions) to facilitate MBB and low latency communication multiplexing with limited signaling.

說明書

In some examples, the preemption and permission indication manager 1415 may determine to transmit preemption indications pertaining to the uplink transmissions on the carrier. The grant manager 1430 may transmit an uplink grant in a first downlink control channel for an uplink transmission on the carrier from the UE. In some examples, the preemption and permission indication manager 1415 may avoid transmitting a preemption indication indicating that the uplink transmission is to be preempted for another transmission. In some examples, the communications manager 1405 may receive an entirety of the uplink transmission based on the avoiding.

In some examples, the preemption and permission indication manager 1415 may determine to transmit permission indications pertaining to the uplink transmissions on the carrier. The grant manager 1430 may transmit an uplink grant in a first downlink control channel for an uplink transmission on the carrier from the UE. In some examples, the preemption and permission indication manager 1415 may transmit a permission indication indicating that the UE has permission to transmit the uplink transmission. In some examples, the communications manager 1405 may receive the uplink transmission based on transmitting the permission indication.
