Provided are a user equipment (UE) supporting multi subscriber identity module (SIM) multi standby (MSMS), and an operating method of the UE. An operating method of a UE includes performing communication associated with a SIM of the UE with a network in a radio resource control (RRC) idle mode, triggering measurement of a neighbor cell based on a neighbor cell measurement rule that considers a measurement value of a serving cell signal and a number of cell reselection ping-pongs that occurred between the serving cell and the neighbor cell, and reselecting the neighbor cell based on at least one cell reselection criterion considering the measurement value and the number of cell reselection ping-pongs.

Provided is a correlation scheme selecting apparatus and method that can acquire initial synchronization efficiently by calculating frequency error criterion threshold between correlation schemes and selecting a correlation scheme for each region when a correlation value is calculated for initial sync in a communication system with carrier frequency errors. The method for selecting a correlation scheme based on a carrier frequency error includes: calculating mis-detection probability values based on a normalized frequency offset for each correlation scheme; determining as a frequency-error criterion threshold a crossing point of graphs of the calculated mis-detection probability values for each correlation scheme; and selecting a correlation scheme based on the determined frequency-error criterion threshold.

Provided is a method for detecting frame sync and frame structure in a satellite broadcasting system. The method for detecting frame sync and frame structure includes the steps of: calculating differential correlation values of reception symbols; generating index sequences of reception symbols whose differential correlation values calculated above exceed a threshold value; calculating positions estimated as frame start points which correspond to a total frame number based on the number of symbols per frame for each frame structure; and detecting frame sync and frame structure based on the umber of positions where the above-calculated frame start point estimated positions and the above-generated index sequences are matched.
