1. A method for wireless communications at a user equipment (UE), comprising:
monitoring a plurality of synchronization signal resources, each synchronization signal resource of the plurality of synchronization signal resources associated with a beam of a set of beams;
determining that a number of configured repetitions of a random access message from a network entity satisfies a threshold value;
transmitting, to the network entity using a first beam, an uplink random access message comprising beam information based at least in part on determining that the number of configured repetitions satisfies the threshold value, the beam information comprising one or more channel quality measurement values associated with a second beam, wherein the one or more channel quality measurement values comprise one or more offset values from a first channel quality measurement value associated with the second beam;
receiving, based at least in part on the beam information comprising the one or more channel quality measurement values associated with the second beam, a downlink random access message using the second beam; and
establishing a connection with the network entity based at least in part on the uplink random access message and the downlink random access message.
