Carrier 1
(50 MHz - 270 RB scs=15 kHz)
offsetToCarrier
Carrier
• Maximum set of consecutive RBs used by a cell for a given numerology
• 1 carrier instance for each numerology actually configured in the cell
Point A
• Absolute reference common to all carriers
• Does not necessarily coincide with CRB #0 of a carrier
• Signaled to UE by absoluteFrequencyPointA (ARFCN)
offsetToCarrier
• Provides position of carrier relative to point A
• Expressed in number of RB using the carrier numerology
Carrier bandwidth
• Constrained by max 3300 tones (275 RB) but in practice
reduced to max 273 RB
• Carriers associated to different numerology do not
necessarily cover the same frequency span
• Necessity to provide a relative positioning of each carrier
