Aperiod tracking reference signal

Abstract:

Methods, systems, and devices for wireless communications are described. A base station may determine that a triggering event associated with a user equipment (UE) has occurred. The UE may receive, based at least in part on an occurrence of a triggering event associated with the UE, a trigger signal that identifies resources to be used for transmission of an aperiodic tracking reference signal (TRS). The UE may receive the aperiodic TRS based at least in part on the trigger signal and the identified resources. The UE may perform at least one of a tracking function, or a synchronization function, or an alignment function, or a combination thereof, in response to the occurrence of the triggering event and based at least in part on the aperiodic TRS.
