Frequency and Bandwidth DetectionLTE support various different options of channel bandwidth, which are 1.4, 3, 5, 10, 15, 20 Mhz. How can a UE figure out which bandwidth to use when it try to attach to the network ? This is the procedure in which UE figures out the bandwidth. i) ii) Decode PSS (Primary Sync Signal)
iii) Decode SSS (Secondary Sync Signal) iv) with the result of step ii) and iii), UE can detect cell specific Reference Signal
v) Decode BCH which occupies 72 subcarriers (6 RBs) at the center frequency.
vi)
