TEMPORARY REFERENCE SIGNAL FOR FAST SECONDARY CELL ACTIVATION

Abstract:

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a secondary cell activation message that indicates a secondary cell is to be activated at the UE in addition to a primary cell. The UE may identify, based at least in part on the secondary cell activation message, a slot location of a first portion of aperiodic reference signals for cell activation measurements and a slot offset between the first portion of the aperiodic reference signals and a second portion of the aperiodic reference signals, the slot offset comprising non-consecutive slots with respect to the slot location. The UE may measure one or more characteristics of the secondary cell based at least in part on the aperiodic reference signals.
