Abstract: Methods and systems are provided to perform an adaptive access procedure on a multi-subscriber identity module (SIM) wireless communication device having at least a first SIM and a second SIM associated with a shared radio frequency (RF) resource. The wireless communication device may detect that signaling on a random access channel (RACH) is required in order to establish access to a first network on a modem stack associated with the first SIM, identify a first protection window having a duration based on timing of an expected response by the first network to signaling on the RACH, and determine whether a tune-away period to decode a paging channel in a second network supported by the second SIM is scheduled to occur within the first protection window. If so, the wireless communication device may postpone signaling on the RACH until completion of the scheduled tune-away period.

Abstract: The present disclosure presents a method and apparatus for regaining service at a user equipment. For example, the disclosure presents a method for receiving a neighbor cell list from a serving cell, and scanning to identify target cells by the user equipment, wherein the target cells include neighbor cells included in the neighbor cell list and detected cells not included in the neighbor cell list. In addition, such an example method may include determining that the user equipment cannot successfully camp on any one of the neighbor cells, and attempting to camp on one of the detected cells. As such, an improved method and apparatus for regaining service at a user equipment may be achieved.

Abstract: Methods, systems, and devices for wireless communications are described. In a wireless communications system, a user equipment (UE) may be scheduled to perform a first measurement or paging activity associated with a target cell operating according to a first target cell configuration that is different from a serving cell operating according to a first serving cell configuration of the UE. In some cases, the UE may determine that the UE has performed a previous measurement or paging activity associated with the target cell while being served by the serving cell, the cells operating according to previous cell configurations. The UE may compare at least one of the first and previous target cell configurations or the first and previous serving cell configurations, and may perform the first measurement or paging activity using a script, where the script is either reused or rebuilt based on comparing the cell configurations.
