18. A method for wireless communication at a base station, comprising:
receiving, from a user equipment (UE), an initial random access request to establish a wireless connection with the base station;
transmitting a control channel order to the UE responsive to the initial random access request;
determining, based at least in part on the control channel order, a set of resources for one or more modified random access requests;
monitoring for the one or more modified random access requests using the determined set of resources; and
transmitting a random access response to the UE using one or more beamforming parameters that are based at least in part on measurements associated with the one or more modified random access requests.
