Claim Text:
1. A method for decoding system information comprising: determining, by a processing device, whether a system information block (SIB) Presence Bitmap for a currently selected base station is stored in a memory of a wireless communication device associated with the processing device; controlling, by the processing device, SIB decoding for the currently selected base station according to either a SIB Presence Bitmap of a last serving base station or the SIB Presence Bitmap for the currently selected base station stored in the memory selected as a selected SIB Presence Bitmap, based on a result of the determining whether the SIB Presence Bitmap is in the memory; when the SIB decoding is determined to be successful for an instance of a SIB within a SIB periodicity transmitted by the currently selected base station, updating, by the processing device, the SIB Presence Bitmap for the currently selected base station stored in the memory according to detection and decoding status in radio frames and subframes in which the SIB was transmitted by the currently selected base station; and when (i) the SIB decoding is determined to be unsuccessful for the instance of the SIB and (ii) the SIB decoding is determined to be successful after the SIB decoding is performed for all remaining instances of the SIB within the SIB periodicity, updating, by the processing device, the SIB Presence Bitmap for the currently selected base station stored in the memory according to detection and decoding status in radio frames and subframes in which the SIB was transmitted by the currently selected base station.
