Abstract: Apparatus and methods of wireless communication with a network entity by a user equipment includes identifying, by the user equipment, a change in availability of an enhanced uplink channel. Further, these aspects include waiting for an uplink data indication to trigger a cell update procedure, in response to the identified change in availability of an enhanced uplink channel. Also, these aspects include receiving a reconfiguration message before triggering of the cell update procedure, and receiving the uplink data indication, wherein the uplink data indication corresponds to a Layer 2 Acknowledgement or uplink data. Additionally, these aspects include handling the race condition between the reconfiguration message and the uplink data indication.

Abstract: The present disclosure presents a method and an apparatus for managing radio resource control (RRC) state transitions at a user equipment (UE). For example, the method may include transmitting a reconfiguration complete message to a network entity, starting a reselection delay timer simultaneously with the transmitting of the reconfiguration complete message, identifying initiation of a cell reselection procedure at the UE, delaying the cell reselection procedure at the UE until the UE receives a layer 2 acknowledgement (L2 ACK) message from the network entity, stopping the reselection delay timer in response to receiving the L2 ACK message, and transitioning the UE to a cell_paging channel (cell_PCH) state from a cell_forward access channel (cell_FACH) state after the stopping of the reselection delay timer. As such, managing RRC state transitions at a UE may be achieved.
