Aspects described herein relate to receiving a timing adjustment (TA) command indicating to adjust timing for an uplink transmission in a time division, adjusting, by the UE and based on the TA command, the timing for the uplink transmission in the time division, and where the uplink transmission includes an overlapping portion that at least partially overlaps in time with a previous uplink transmission scheduled for transmission in a previous time division, due to the TA command, and a non-overlapping portion that does not at least partially overlap in time with the previous uplink transmission, refraining from transmitting the non-overlapping portion of the uplink transmission that is scheduled in the time division. Other aspects relate to transmitting the TA command and not receiving an overlapping uplink transmission.
