Abstract
Various aspects relate to acquisition of system information (SI). In some examples, a UE uses a guard timer to control how long the UE attempts to acquire a particular type of SI. In some examples, a UE that has entered a cell may determine whether there are any remaining paging occasions (e.g., that may indicate an SI update) during a period of time. If there is an insufficient number of paging occasions remaining (e.g., zero or one), the UE may monitor for broadcast SI. In some examples, after sending a request for SI to a base station, a UE may also periodically monitor for SI broadcast by the base station (e.g., to avoid potential delays in obtaining the SI). In some examples, if a UE does not acquire SI, the UE may use default SIB information (e.g., that expedites reselection to another cell).
