US 11,606,799 B2 · Preemption indication and permission indication management for mobile broadband and low latency communication multiplexing

Abstract

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.

Dependent claims

A method for wireless communication at a user equipment (UE), comprising:

receiving a preemption monitoring indication in a grant of resources for an uplink transmission, wherein the grant is received on a first downlink control channel, and the preemption monitoring indication indicates whether the uplink transmission is permitted to be preempted by a preemption indication received on a second downlink control channel and wherein the preemption monitoring indication is indicative of a priority associated with the uplink transmission;
monitoring the second downlink control channel for the preemption indication;
and
determining, based at least in part on the preemption monitoring indication and a result of the monitoring, whether to transmit the uplink transmission in accordance with the grant of resources.

1 more element

A method for wireless communication at a base station, comprising:

identifying an uplink transmission from a user equipment (UE) to be scheduled;
determining whether to include a preemption monitoring indication in a grant of resources for the uplink transmission based at least in part on whether the uplink transmission is allowed to be preempted by another transmission;
transmitting radio resource control (RRC) signaling that configures the UE to monitor a first downlink control channel for the preemption monitoring indication, wherein the preemption monitoring indication is indicative of a priority associated with the uplink transmission;
and
transmitting the grant of resources for the uplink transmission on the first downlink control channel, the grant including the preemption monitoring indication indicating whether the uplink transmission is permitted to be preempted by a preemption indication transmitted on a second downlink control channel based at least in part on a result of the determination.

2 more elements

An apparatus for wireless communication at a user equipment (UE), comprising:

a processor, memory in electronic communication with the processor;
and instructions stored in the memory and executable by the processor to cause the apparatus to:
receive a preemption monitoring indication in a grant of resources for an uplink transmission, wherein the grant is received on a first downlink control channel, and the preemption monitoring indication indicates whether the uplink transmission is permitted to be preempted by a preemption indication received on a second downlink control channel and wherein the preemption monitoring indication is indicative of a priority associated with the uplink transmission;
monitor the second downlink control channel for the preemption indication;
and
determine, based at least in part on the preemption monitoring indication and a result of the monitoring, whether to transmit the uplink transmission in accordance with the grant of resources.

3 more elements
