Channel raster and synchronization signal raster for nr unlicensed spectrum

An apparatus for determining a plurality of data objects, each data object corresponding to a New Radio (NR) channel using a first subcarrier spacing (SCS) and comprising an NR channel raster position and an Synchronization Signal and Physical Broadcast Channel (SSB) raster position for each NR channel;

• the apparatus comprising:
• a processor;
• and
• a memory storing instructions that, when executed by the processor, configure the apparatus to:
• determine, for each data object, the NR channel raster position, wherein the NR channel raster position comprises a Radio Frequency (RF) reference frequency calculated using an Absolute Radio Frequency Channel Number (NR-ARFCN);
• calculate Global Synchronization Channel Number (GSCN) values for the NR channel corresponding to each data object;
• determine a number of Physical Resource Blocks (PRBs) of the NR channel (NRB) corresponding to each data object based on the first SCS and a bandwidth of the given NR channel;
• determine a placement for the NR channel raster position of each data object;
• compute edges of each NR channel corresponding to each data object based on the center frequency of the given NR channel and the placement of the NR channel raster position of the data object;
• calculate the edges of an SSB of the NR channel corresponding to each data object based on the edges of the given NR channel;
• and
• determine the SSB raster position of each data object based on the edges of the SSB of the NR channel corresponding to the data object.
