1. A user equipment apparatus, comprising:
at least one processor; and
at least one memory storing instructions which, when executed by the at least one processor, cause the user equipment apparatus at least to:
perform an initial cell search of one or more cells on a network, wherein performing the initial cell search includes scanning through a plurality of SSB entries with a synchronization raster, and
wherein the synchronization raster includes a cluster of three synchronization raster points positioned every 600 kHz, and wherein, in case that the user equipment apparatus supports both a 3 MHz channel bandwidth and a 5 MHz channel bandwidth, the instructions, when executed by the at least one processor, further cause the user equipment apparatus to:
scan through a first range of the plurality of SSB entries, where a first range of synchronization raster points is given by:
(N*1200 kHz)+(M*50 kHz),
scan through a second range of the plurality of SSB entries, where a second range of synchronization raster points is given by:
600 kHz+(N*1200 kHz)+(M*50 kHz), and
scan through a third range of the plurality of SSB entries, where a third range of synchronization raster points is given by:
120 kHz+(N*1200 kHz)+(M*50 kHz),
wherein values of N range from 1 to 2499, and
wherein values of M are 1, 3, and 5.
