1. A method for wireless communication at a user equipment (UE), comprising:
transmitting, via a sidelink channel, a plurality of beamformed repetitions of a packet in a plurality of directions, wherein the plurality of directions correspond to a plurality of quality of service (QoS) profiles configured for transmission of the packet, and wherein each direction of the plurality of directions is associated with a different hybrid automatic repeat request process of a plurality of hybrid automatic repeat request processes; and
transmitting, via the sidelink channel, at least one beamformed retransmission of the packet in a subset of directions of the plurality of directions based at least in part on a subset of QoS profiles of the plurality of QoS profiles associated with the subset of directions, a negative acknowledgment received for the packet corresponding to the subset of directions, or both, wherein each direction of the subset of directions is associated with a different hybrid automatic repeat request process of a subset of the plurality of hybrid automatic repeat request processes.
