Abstract: Various solutions for mobile country code recognition with respect to user equipment in mobile communications are described. An apparatus may measure a received signal strength. The apparatus may determine a mobile country code (MCC) according to the received signal strength. The apparatus may determine a frequency band search order according to the determined MCC. The apparatus may search a suitable cell according to the frequency band search order. The apparatus may camp the suitable cell.

Abstract: Techniques pertaining to a machine-learning assisted environment detection framework for self-adapting inter-radio access technology (inter-RAT) steering strategy in wireless communications are described. A user equipment (UE) extracts one or more feature metrics regarding a wireless network environment based at least partially on sensor information received from one or more sensors of the UE and radio frequency (RF) signal information from a RF circuit of the UE. The UE identifies a scenario with respect to a current status of the wireless network environment according to the one or more feature metrics. In response to identifying the scenario, the UE performs a RAT-related operation.

Abstract: Various pertaining to ultrafast cell selection in a wireless device are described. An apparatus stores information related to at least one of: (a) one or more ever-camped cells having been camped on by the apparatus previously, and (b) one or more ever-detected cells having been detected by the apparatus previously. The apparatus performs a cell selection procedure using the stored information responsive to occurrence of an event, thereby reducing cell search time, master information block (MIB) decoding time and system information block (SIB) decoding time.

Abstract: A user equipment terminal (UE) performs cell search in a wireless network. The UE determines a search pattern based on statistics of search trials performed at one or both of a location and time in a recurrent time cycle. The search pattern includes a sequence of alternating search durations and non-search durations for a configurable number of searches. Furthermore, the search pattern includes the search durations or the non-search durations that increase, decrease, or no-change according to probability derived from the statistics. The UE performs the cell search according to the search pattern.
