Original Abstract Submitted
a random access channel (rach)-less conditional cell switch is provided. a user equipment (ue) receives and stores a candidate cell configuration including an execution condition of a conditional cell switch to the candidate cell. the ue selects the candidate cell as a target cell for the conditional cell switch on determination that the execution condition is met. the ue determines whether a valid timing advance (ta) and a valid uplink (ul) grant for initial ul transmission to the target cell is available. when a valid ta and a valid ul grant are available, ue transmits initial ul transmission to the target cell using the valid ta and the valid ul grant. when a valid ta is unavailable, the ue performs random access procedure to the target cell. when a valid ul grant is unavailable, the ue transmits a scheduling request to the target cell.
