Abstract
One disclosure of this specification provides a method for receiving a synchronization signal block (SSB) by a user equipment (UE). The method may include: determining frequency locations of multiple SSBs; and receiving at least one SSB among the multiple SSBs. The multiple SSBs may be configured to be arranged spaced apart from each other by a predetermined offset. The at least one SSB may be located at an interval of 1.2 MHz on a frequency axis.
Claims15
A method performed by a user equipment (UE) in a new radio (NR) system, the method comprising:
- receiving, from a NR cell of a base station, a synchronization signal block (SSB) at a frequency position;
- and
- performing an initial access procedure for the NR cell of the base station based on the received SSB,
- wherein the frequency position of the SSB received from the NR cell exists in a NR band which is re-farmed from a long term evolution (LTE),
- wherein the NR band uses a channel raster of 100 kHz and the SSB uses a subcarrier spacing of 15 kHz,
- wherein the frequency position of the SSB is one of (i) a first plurality of frequency positions that are equally spaced apart by 1.2 MHz, (ii) a second plurality of frequency positions that are equally spaced apart by 1.2 MHz, or (iii) a third plurality of frequency positions that are equally spaced apart by 1.2 MHz, and
- wherein the second plurality of frequency positions is shifted by 100 kHz relative to the first plurality of frequency positions, the third plurality of frequency positions is shifted by 100 kHz relative to the second plurality of frequency positions, and the third plurality of frequency positions is shifted by 200 kHz relative to the first plurality of frequency positions.
