1. An apparatus for wireless communication at a user equipment (UE), comprising:
a memory; and
one or more processors, coupled with the memory, configured to:
receive, from a base station, a configuration message indicating a configured grant—small data transfer (CG-SDT) group for the UE, wherein the CG-SDT group is associated with a downlink beam of the base station and one or more CG-SDT occasions;
validate uplink timing alignment, on an uplink carrier configured with the one or more CG-SDT occasions, before transmitting an uplink communication within the one or more CG-SDT occasions; and
transmit, to the base station and within the one or more CG-SDT occasions, the uplink communication based at least in part on the downlink beam of the base station used for transmitting a reference signal, wherein the uplink communication is transmitted on the uplink carrier with valid uplink timing alignment, using a waveform indicated by radio resource control (RRC) signaling.
