1. A method wireless communication by a user equipment (UE), comprising:
detecting that the UE is simultaneously connected to a source base station (BS) of a source cell and a target BS of a target cell during a handover of the UE from the source cell to the target cell;
detecting during the handover at least one of a first transmission time of a first uplink transmission scheduled for the source cell at least partially overlaps a second transmission time of a second uplink transmission scheduled for the target cell, or a time interval between the first and second transmission times is below a threshold, wherein the UE is capable of transmitting only one of the first uplink transmission or the second uplink transmission;
transmitting one of the first or second uplink transmissions at the respective first or second transmission time, wherein a decision relating to transmitting which one of the first or second uplink transmissions is based on a priority associated with at least one of the first uplink transmission or the second uplink transmission and wherein the transmitting comprises transmitting the one of the first or second uplink transmissions jointly coded with a remaining one of the first or second uplink transmissions using a first beam assigned to the source cell or the target cell; and
transmitting at a next available slot, the one of the first or second uplink transmissions jointly coded with the remaining one of the first or second uplink transmissions using a second beam assigned to the remaining one of the source cell or the target cell.
