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.

Abstract: The present disclosure presents a method and an apparatus for cell reselection during a SRNS relocation at a UE. For example, the disclosure presents a method for stopping signaling radio bearers (SRBs) sending a response message for the first Cell Update Confirm or the URA Update Confirm message and waiting for a layer two acknowledgement (L2 ACK) message from the network entity, triggering a second Cell Update or a URA Update procedure in a newly selected serving cell of the UE when waiting for the L2 ACK message from the network entity and waiting for the second Cell Update Confirm or the URA Update Confirm message, and performing a corrective action at the UE after the triggering of the second Cell Update or the URA Update procedure when the UE is waiting for the L2 ACK message from the network entity. As such, a cell reselection during a serving radio network subsystem (SRNS) relocation at a UE may be achieved.

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: Various aspects of the present disclosure enable a plurality of mobile devices (UEs) within a cell to spread out in time their respective transmissions of signaling messages, such as cell update messages, when the network enables or disables enhanced uplink (EUL, sometimes referred to as high-speed uplink packet access or HSUPA) while the UE is in the CELL_FACH state, by changing SIB5 or SIB5bis. In this way, the network load may be reduced, and a network blockage that otherwise might result from large numbers of UEs simultaneously transmitting the cell update message can be avoided. According to one example, a network node may be configured to distribute CELL_UPDATE messages or procedures to UEs when the network node enables or disables EUL in CELL_FACH by changing SIB5 or SIB5bis over time to reduce the network load. According to another example, a UE may be configured for utilizing a random timer or back-off timer to defer cell updates.

Abstract: This disclosure provides systems, methods and apparatuses for enabling downlink throttling, such as for thermal mitigation. For example, a user equipment (UE) may transmit channel state feedback (CSF) with a report of a first rank that is less than a second rank associated with a channel condition and may communicate with a base station using a configuration associated with the first rank and without a set of sounding reference signals (SRSs). Alternatively, the UE may transmit one or more SRSs using a configuration associated with the first rank. In this way, by refraining from transmission of the SRSs or by adjusting the configuration the SRSs, the UE causes the base station to support downlink throttling.

Abstract: The disclosure provides for a UE handling messages in wireless communication. The disclosure provides for a UE partially exchanging a first signaling-related message associated with a first UE configuration with a network entity and triggering a state transition message that initiates a change to a second UE configuration different from the first UE configuration. In an aspect, the UE determines that the first message has not been successfully received or successfully transmitted. In an aspect, the UE sends an indication message to coordinate discarding of the first message with the network entity and receives, after sending the indication message, a second signaling-related message associated with the second UE configuration. In another aspect, the UE, after partially sending a signaling-related message, receives a reconfiguration request associated with a second UE configuration. In an aspect, the UE determines that the message has not been successfully transmitted and causes a reconfiguration failure.
