SYNCHRONIZATION SIGNAL BLOCK DESIGN USING A SINGLE CARRIER QUADRATURE AMPLITUDE MODULATION WAVEFORM - A simplified explanation of the abstract

This abstract first appeared for US patent application 17443879 titled 'SYNCHRONIZATION SIGNAL BLOCK DESIGN USING A SINGLE CARRIER QUADRATURE AMPLITUDE MODULATION WAVEFORM

Simplified Explanation

The patent application is related to wireless communication and specifically focuses on a user equipment (UE) receiving a synchronization signal block (SSB) transmitted using a single carrier quadrature amplitude modulation (SC-QAM) waveform. The SSB includes a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and physical broadcast channel (PBCH) data. The UE uses the SSB for initial channel access.

• The patent application describes a method for transmitting synchronization signals in wireless communication using a single carrier quadrature amplitude modulation (SC-QAM) waveform.
• The synchronization signal block (SSB) includes a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and physical broadcast channel (PBCH) data.
• The SSB has a uniform bandwidth allocation for each of the PSS, SSS, and PBCH data.
• The user equipment (UE) receives the SSB and performs initial channel access based on the information contained in the SSB.

Original Abstract Submitted

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a synchronization signal block (SSB) transmitted using a single carrier quadrature amplitude modulation (SC-QAM) waveform, wherein the SSB has a uniform bandwidth allocation for each of a primary synchronization signal (PSS) included in the SSB, a secondary synchronization signal (SSS) included in the SSB, and physical broadcast channel (PBCH) data included in the SSB. The UE may perform initial channel access based at least in part on the SSB. Numerous other aspects are described.
