Abstract
Wireless communications systems and methods related to performing random access procedures. A base station (BS) receives, from a user equipment (UE), a plurality of random access preambles from a plurality of beam directions, wherein each of the plurality of random access preambles is received from a different beam direction, and wherein the plurality of random access preambles are associated with multiple random access opportunities of a random access attempt. The BS sends, in response to the plurality of random access preambles, a plurality of random access response (RAR) messages in the plurality of beam directions.
