Abstract
Methods, systems, and devices for wireless communication are described. A base station may identify that data is available to be transmitted to a user equipment (UE) that is operating in a discontinuous reception (DRX) mode. The base station may configure a plurality of UE-specific reference signals for transmission to the UE, each UE-specific reference signal indicating a UE identifier and an availability of data for the UE. The UE may receive the UE-specific reference signal, and identify that data is available for the UE from the base station. The UE may then transmit a beam recovery signal to the base station that includes an identifier for the transmit beam used by the UE to transmit the beam recovery signal. The base station may transmit, using a beam sweeping configuration, the plurality of UE-specific reference signals.
