## Abstract

The present application relates to devices and components including apparatus, systems, and methods of scheduling transmission of synchronization signal blocks (SSBs) at a subcarrier spacing (SCS) of 480 or 960 kHz.

## Claims

### Claim 1

One or more non-transitory computer-readable media, having instructions that, when executed, cause processing circuitry to:
generate, with a subcarrier spacing (SCS) of S kHz, a first plurality of synchronization signal blocks (SSBs) for transmission on a first set of consecutive symbols and a second plurality of SSBs for transmission on a second set of consecutive symbols, wherein S has a value of 480 or 960; and
processing an uplink data transmission using a 960 kHz SCS, wherein the uplink data transmission is received between a transmission of the first plurality of SSBs and a transmission of the second plurality of SSBs; and
wherein the transmission of the first plurality of SSBs and the transmission of the second plurality of SSBs occur within an ordered time sequence of R consecutive symbols, and wherein:
R has a value of (112×P), where P has a value of (S/480) and each symbol in the ordered time sequence is indexed from 0 to (R−1), and, for each SSB of the first plurality of SSBs, an index Y1 of a starting symbol of the SSB has a value of the following expression: Y1=(16×P)+ (4×m), and, for each SSB of the second plurality of SSBs, an index Y2 of a starting symbol of the SSB has a value of the following expression: Y2=(64×P)+ (4×m), where m is any integer from 0 to [(8×P)−1];
R has a value of (28×P), where P has a value of (S/480) and each symbol in the ordered time sequence is indexed from 0 to (R−1), and, for each SSB of the first plurality of SSBs, an index Y1 of a starting symbol of the SSB has a value of the following expression: Y1=(4×P)+ (4×m), and, for each SSB of the second plurality of SSBs, an index Y2 of a starting symbol of the SSB has a value of the following expression: Y2=(16×P)+ (4×m), where m is any integer from 0 to [(2×P)−1]; or
R has a value of (28×P), where P has a value of (S/480) and each symbol in the ordered time sequence is indexed from 0 to (R−1), and, for each SSB of the first plurality of SSBs, an index Y1 of a starting symbol of the SSB has a value of the following expression: Y1=[(2×P)+ (4×m)] or [(8×P)+ (4×m)], and, for each SSB of the second plurality of SSBs, an index Y2 of a starting symbol of the SSB has a value of the following expression: Y2=[(16×P)+ (4×m)] or [(22×P)+ (4×m)], where m is any integer from 0 to (P−1).
