1. A method of wireless communication at a user equipment (UE), comprising:
receiving one or more pre-grant transmissions during a contention period, wherein each pre-grant transmission is associated with a beam of a plurality of beams, and wherein the plurality of beams are in a millimeter wave (mmWave) frequency range;
decoding the one or more pre-grant transmissions;
determining, after successfully decoding the one or more pre-grant transmissions, whether the one or more decoded pre-grant transmissions satisfy one or more quality conditions;
transmitting, during the contention period, one or more reference signals based on determining that at least one decoded pre-grant transmissions of the one or more decoded pre-grant transmissions satisfy the one or more quality conditions;
receiving one or more grant transmissions responsive to the one or more reference signals; and
receiving a data transmission based on the one or more grant transmissions.
