摘要： 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.

摘要： Aspects of the present disclosure generally relate to managing decoding of system information blocks (SIBs) at a user equipment (UE) and managing SIB transmissions at a base station. For example, the described aspects at the UE may include detecting a trigger event for decoding one or more SIBs received from a cell and determining to avoid decoding of at least one SIB received from the cell in response to the detected trigger event and a mobility pattern of the UE. The described aspect at the UE may further include using a stored version of the at least one SIB for communication with the first cell.

摘要： 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.

摘要： 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.

摘要： Aspects described herein relate to throttling packet-switched (PS) call establishment in wireless communications. A circuit-switched (CS) call can be conducted by using a first radio access technology (RAT). A cell update (CU) procedure for a PS call using a second RAT can be detected as due to one or more conditions. A cause for the one or more conditions can be determined based on one or more parameters related to a transmitter or receiver. PS call establishment attempts can accordingly be throttled based at least in part on determining the cause for the one or more conditions

摘要： 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.
