Patent drawing
Patent drawing from the official filing.

Apple describes a method for two devices to talk directly without a cell tower. If a signal gets weak, the devices use simple 'yes' or 'no' signals to quickly find a better angle for their antennas.

Why it mattersThis helps phones stay connected in crowded places where cell service is weak, like at concerts or in stadiums.

In the filing’s own words

Methods, systems, apparatuses, and computer programs method for beam recovery is disclosed. In one aspect, a method can include transmitting, by a first UE, a unicast packet to a second UE using a preconfigured set of transmission serving beams, receiving, by the first UE, at least one ACK or NACK from the second UE in a physical sidelink feedback channel (PSFCH), and transmitting, by the first UE, a transmission using a transmission serving beam determined based on the PSFCH used to receive ACK or NACK.
