Frame based operation for millimeter wave (mmWave) with receiver based contention

An apparatus for wireless communication, comprising:

• at least one processor;
• and
• a memory coupled to the at least one processor,
• wherein the at least one processor is configured to:
• receive 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;
• decode the one or more pre-grant transmissions;
• determine, 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;
• transmit, 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;
• receive one or more grant transmissions responsive to the one or more reference signals;
• and
• receive a data transmission based on the one or more grant transmissions.

A method of wireless communication by a network entity, comprising:

• transmitting two or more pre-grant transmissions during a contention period, wherein each pre-grant transmission of the two or more pre-grant transmissions is sent via a different beam of a plurality of beams, and wherein the plurality of beams are in a millimeter wave (mmWave) frequency range;
• receiving one or more reference signals responsive to the two or more pre-grant transmissions during the contention period using two or more beams of the plurality of beams;
• determining interference for each reference signal of the one or more reference signals;
• determining whether to transmit data for at least one pre-grant transmission of the two or more pre-grant transmissions based on the interference for each reference signal;
• transmitting one or more grant transmissions based on determining that the interference for a particular reference signal of the one or more reference signals satisfied a transmission condition;
• and
• transmitting a data transmission via a particular beam of the plurality of beams based on the one or more grant transmissions.
