Fast activation and deactivation for low latency communications

Abstract:

Methods, systems, and devices for wireless communications are described. As described herein, a service type may be configured, activated, and utilized for subsequent communications according to the service type. For example, a user equipment (UE) may monitor a downlink control channel associated with the service type based on configuring the service type and activating the service type, receive downlink messages associated with the service type, or transmit uplink messages associated with the service type. In some cases, the service type may be activated by transmitting a medium access control (MAC) control element (CE) or a downlink control information (DCI) message. When traffic associated with the service type is no longer present, the service type may be deactivated based on a deactivation indication and/or a deactivation timer. In some cases, the service type may include an ultra-reliable low latency communication (URLLC) service or a low latency service.
