11. A method for wireless communications at a first wireless device, comprising:
selecting a directional beam from a set of one or more directional beams for transmitting a message to a second wireless device in a shared radio frequency spectrum band; and
transmitting, to the second wireless device and using a quantity of spatial streams, the message in the shared radio frequency spectrum band via the directional beam, wherein the message is transmitted without sensing a channel based at least in part on the quantity of spatial streams and a first metric of one or more metrics associated with the selected directional beam being greater than a first threshold or based at least in part on the quantity of spatial streams and the first metric being less than a second threshold.
