Network triggered reference signal coverage extension in wireless communication

Abstract:

Aspects of the present disclosure provide various apparatuses and methods for extending a reference signal to facilitate carrier aggregation (CA). In some examples, a network includes a primary cell and one or more secondary cells that use a millimeter wave (mmW) carrier. When a UE is beyond the range of a reference signal from the secondary cell, the primary cell may trigger the secondary cell to increase the range of its reference signal using a higher gain beam and/or reference signal repetition.
