1. A system for supporting a non-blind scheduling of a physical downlink control channel (PDCCH) aggregation level (AL) for a search space, the system comprising:
an antenna array comprising one or more antenna elements; and
one or more processors configured to execute operations comprising:
receiving one or more signals corresponding to a device;
receiving a request for a random-access channel response from the device;
determining a radio frequency condition for the device based on the one or more signals; and
upon receiving the request and based on the radio frequency condition, broadcasting an assigned physical random access channel (PRACH) preamble group to the device for scheduling the PDCCH AL, the assigned PRACH preamble group corresponding to the search space.
