1. A method for wireless communication at a user equipment (UE), comprising:
receiving a discontinuous reception (DRX) mode configuration that configures a first transmit beam and a second transmit beam of a first set of transmit beams for reception of a wakeup signal to wake the UE from a sleep state of a DRX mode for a DRX on duration, wherein the wakeup signal for the UE is transmitted by an access network entity using the first transmit beam and the second transmit beam of the first set of transmit beams;
receiving, while operating in the sleep state of the DRX mode, the wakeup signal via one of the first transmit beam or the second transmit beam;
receiving, during the DRX on duration and based at least in part on receiving the wakeup signal, a set of signals transmitted by the access network entity using a second set of transmit beams and in accordance with a beam sweeping configuration, the set of signals comprising reference signals, synchronization signals, or a combination thereof;
selecting a transmit beam from the second set of transmit beams for the UE to use to receive downlink transmissions from the access network entity;
transmitting, during the DRX on duration, an indication of the selected transmit beam to the access network entity; and
receiving, based at least in part on transmitting the indication, a control channel transmission scheduling data channel resources over the selected transmit beam during the DRX on duration.
