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.

Techniques for prioritizing non-scheduled data are described. Non-scheduled data to be transmitted on a non-scheduled MAC-d flow having a non-scheduled priority and scheduled data to be transmitted on a scheduled MAC-d flow having a scheduled priority may be identified by a user equipment (UE). The UE may transmit the non-scheduled MAC-d flow and the scheduled MAC-d flow according to a priority condition. In one aspect, the UE may receive a pre-allocation of power associated with a non-empty non-scheduled MAC-d flow. Based on a priority condition that the non-scheduled priority is a highest priority, the UE may apply all of the pre-allocation of power when transmitting the non-scheduled MAC-d flow. In one aspect, based on a priority condition that the non-scheduled priority is a lower priority, the UE may adjust the non-scheduled priority and/or the scheduled priority so that the non-scheduled priority is a higher priority.
