Uplink sensing with multiple beams in a shared spectrum

An apparatus for wireless communication at a wireless node, comprising:

• a processor,
• memory coupled with the processor, and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• configure a plurality of beams for performing channel access for another wireless node for uplink transmissions;
• transmit a grant of a plurality of sets of resources for uplink transmissions to the other wireless node, each of the plurality of sets of resources associated with one or more beams of the plurality of beams;
• and
• receive an uplink transmission from the other wireless node over at least one beam of the plurality of beams and over at least one set of resources of the plurality of sets of resources.

A method for wireless communication implemented by a wireless node, comprising:

• receiving a grant of a set of resources for an uplink transmission, the grant indicating a plurality of beams for performing channel access for the uplink transmission;
• performing channel access procedures over at least a subset of beams of the plurality of beams;
• and
• transmitting over one or more beams of the subset of beams based at least in part on successful completion of one or more of the channel access procedures.
