Fast activation and deactivation for low latency communications

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

• receiving, from a base station, a configuration for a service type;
• identifying uplink traffic associated with the service type;
• transmitting, to the base station, a scheduling request (SR) associated with the service type based at least in part on identifying the uplink traffic associated with the service type;
• activating a service type mode for monitoring for a grant for the service type based at least in part on transmission of the SR;
• monitoring a downlink channel based at least in part on the configuration for monitoring the service type;
• receiving, from the base station, an uplink grant for the identified uplink traffic via the downlink channel;
• and
• transmitting, to the base station, the uplink traffic associated with the service type based at least in part on receiving the uplink grant.

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

• a processor,
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive, from a base station, a configuration for a service type;
• receive, from the base station, an activation indicator indicating that the UE is to begin monitoring for the service type;
• monitor a downlink control channel associated with the service type based at least in part on the configuration for the service type and receipt of the activation indicator;
• and
• receive a downlink message associated with the service type in accordance with the configuration for the service type.
