Beam indications during random access procedures

A method for wireless communications at a network device, comprising:

• transmitting one or more synchronization signals over a plurality of synchronization signal resources, each synchronization signal resource of the plurality of synchronization signal resources associated with a transmit beam of a set of transmit beams;
• receiving, as part of a random access procedure with a user equipment (UE), a first random access message comprising a preamble via a random access resource in accordance with multiple candidate beams of the set of transmit beams satisfying a channel quality threshold at the UE, wherein reception of the first random access message comprising the preamble via the random access resource indicates that the multiple candidate beams satisfy the channel quality threshold;
• transmitting, based at least in part on receiving the first random access message, an indication of a first beam of the multiple candidate beams;
• and
• establishing a connection with the UE via the first beam.

A user equipment (UE), comprising:

• one or more processors;
• and
• one or more memories coupled with the one or more processors and storing instructions executable by the one or more processors to cause the UE to:
• monitor 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;
• transmit, as part of a random access procedure with a network device, a first random access message comprising a preamble via a random access resource in accordance with multiple candidate beams of the set of beams satisfying a channel quality threshold, wherein transmission of the first random access message comprising the preamble via the random access resource indicates that the multiple candidate beams satisfy the channel quality threshold;
• receive, based at least in part on transmitting the first random access message, an indication of a first beam of the multiple candidate beams;
• and
• establish a connection with the network device via the first beam.
