摘要

The aspects described herein may enable a base station to repeat a downlink control channel based on one or more indications received from a user equipment (UE). This may allow the base station to efficiently use network resources to enhance coverage of downlink control channels for different steps of a network access procedure as needed by a UE. For example, a UE may determine to activate or deactivate repetition of a downlink control channel associated with a network access procedure. The UE may transmit an indication configured to activate or deactivate repetition of the downlink control channel.
